    Two versions (modified pre-test and modified post-test) of PIN-micro code were used to analyse the fuel rod behaviour of three FUMEX experiments. The experience of applying PIN-micro code with its simple structure and old conception of the steady-state operation shows significant difficulties in treating the complex processes like those in FUMEX experiments. These difficulties were partially overcame through different model modifications and corrections based on special engineering estimations and the results obtained as a whole do not seem unreasonable. The calculations have been performed by a group from two Bulgarian institutions in collaboration with specialists from the Kurchatov Research Center. 1 tab., 14 figs., 8 refs.

    Web-based modules may facilitate instruction on core topics in allergy and immunology (AI). Pretests (PTs) have been shown to improve learning in Web-based courses, but their effectiveness in comparison with advance organizers (AOs) is unknown. We performed a randomized controlled trial of a Web-based educational intervention for teaching the practical aspects of allergen immunotherapy (AIT). AI Fellows-in-Training were randomly assigned to receive the introduction to the modules in an AO outline (AO group) or as PT questions (PT group). The primary outcome was the difference in posttest scores between groups. The secondary outcome was the difference in PT and posttest scores in the PT group. Thirty participants in the AO group and 35 in the PT group completed the modules and the posttest. The mean (SD) posttest score for the AO group was 74% (14%) compared with 73% (9%) for the PT group, a mean difference of -1% (95% CI, -7%, 5%; p = 0.67). A multivariate analysis controlling for year-in-training and total time spent on the modules revealed virtually identical results. The mean (SD) PT score for the PT group increased from 49 (10%) to 73% (9%), a mean difference of 24% (95% CI, 19%, 28%; p < 0.0001). Introducing Web-based allergy education with PT questions or an AO resulted in similar posttest scores. Posttest scores in the PT group improved significantly compared with PT scores.

    Baseline neurocognitive assessment plays a critical role in return-to-play decision making following sport-related concussions. Prior studies have assessed the effect of a variety of modifying factors on neurocognitive baseline test scores. However, relatively little investigation has been conducted regarding the effect of pretest exercise on baseline testing. The aim of our investigation was to determine the effect of pretest exercise on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) scores in adolescent and young adult athletes. We hypothesized that athletes undergoing self-reported strenuous exercise within 3 hours of baseline testing would perform more poorly on neurocognitive metrics and would report a greater number of symptoms than those who had not completed such exercise. Cross-sectional study; Level of evidence, 3. The ImPACT records of 18,245 adolescent and young adult athletes were retrospectively analyzed. After application of inclusion and exclusion criteria, participants were dichotomized into groups based on a positive (n = 664) or negative (n = 6609) self-reported history of strenuous exercise within 3 hours of the baseline test. Participants with a positive history of exercise were then randomly matched, based on age, sex, education level, concussion history, and hours of sleep prior to testing, on a 1:2 basis with individuals who had reported no pretest exercise. The baseline ImPACT composite scores of the 2 groups were then compared. Significant differences were observed for the ImPACT composite scores of verbal memory, visual memory, reaction time, and impulse control as well as for the total symptom score. No significant between-group difference was detected for the visual motor composite score. Furthermore, pretest exercise was associated with a significant increase in the overall frequency of invalid test results. Our results suggest a statistically significant difference in ImPACT composite scores between

    The effect of visual arts interventions on development of empathy has not been quantitatively investigated. A study was conducted on the effect of a visual arts-based program on the scores of the Jefferson Scale for Physician Empathy (JSPE). A total of 110 clerks (n = 92) and first-year postgraduate residents (PGY1s) (n = 18) participating in the program were recruited into this study. The 4-hr program covered the subjects of learning to interpret paintings, interpreting paintings relating to medicine, illness and human suffering, the related-topics of humanitarianism and the other humanities fields and values and meaning. The JSPE was completed at the beginning (pretest) and the end (posttest) of the program. There was no significant difference between the pretest and posttest JSPE scores. The average of the scores for the pretest was lower in the subgroup of PGY1s than the subgroup of clerks (p = 0.0358). An increased but not significantly mean posttest JESPE score was noted for the subgroup of PGY1s. Neither the females nor the males had higher posttest JSPE scores than the pretest scores. Although using a structured visual arts-based program as an intervention may be useful to enhance medical students' empathy, our results failed to show a positive effect on the JSPE Scores for a group of clerks and PGY1s. This suggests that further experimental studies are needed if quantitative evaluation of the effectiveness of visual-arts based programs on empathy is to be investigated.

    It is generally assumed that learning in context increases performance. This study investigates the relationship between the characteristics of a paper-patient context (relevance and familiarity), the mechanisms through which the cognitive dimension of context could improve learning (activation of prior knowledge, elaboration and increasing retrieval cues), and test performance. A total of 145 medical students completed a pretest of 40 questions, of which half were with a patient vignette. One week later, they studied musculoskeletal anatomy in the dissection room without a paper-patient context (control group) or with (ir)relevant-(un)familiar context (experimental groups), and completed a cognitive load scale. Following a short delay, the students completed a posttest. Surprisingly, our results show that students who studied in context did not perform better than students who studied without context. This finding may be explained by an interaction of the participants' expertise level, the nature of anatomical knowledge and students' approaches to learning. A relevant-familiar context only reduced the negative effect of learning the content in context. Our results suggest discouraging the introduction of an uncommon disease to illustrate a basic science concept. Higher self-perceived learning scores predict higher performance. Interestingly, students performed significantly better on the questions with context in both tests, possibly due to a 'framing effect'. Since studies focusing on the physical and affective dimensions of context have also failed to find a positive influence of learning in a clinically relevant context, further research seems necessary to refine our theories around the role of context in learning.

    Guideline adherence in physical therapy is far from optimal, which has consequences for the effectiveness and efficiency of physical therapy care. Programmes to enhance guideline adherence have, so far, been relatively ineffective. We systematically developed a theory-based Quality Improvement in Physical Therapy (QUIP) programme aimed at the individual performance level (practicing physiotherapists; PTs) and the practice organization level (practice quality manager; PQM). The aim of the study was to pilot test the multilevel QUIP programme's effectiveness and the fidelity, acceptability and feasibility of its implementation. A one-group, pre-test, post-test pilot study (N = 8 practices; N = 32 PTs, 8 of whom were also PQMs) done between September and December 2009. Guideline adherence was measured using clinical vignettes that addressed 12 quality indicators reflecting the guidelines' main recommendations. Determinants of adherence were measured using quantitative methods (questionnaires). Delivery of the programme and management changes were assessed using qualitative methods (observations, group interviews, and document analyses). Changes in adherence and determinants were tested in the paired samples T-tests and expressed in effect sizes (Cohen's d). Overall adherence did not change (3.1%; p = .138). Adherence to three quality indicators improved (8%, 24%, 43%; .000 ≤ p ≤ .023). Adherence to one quality indicator decreased (-15.7%; p = .004). Scores on various determinants of individual performance improved and favourable changes at practice organizational level were observed. Improvements were associated with the programme's multilevel approach, collective goal setting, and the application of self-regulation; unfavourable findings with programme deficits. The one-group pre-test post-test design limits the internal validity of the study, the self-selected sample its external validity. The QUIP programme has the potential to change physical

    The aim of our study was to determine if a fresh cadaver model is a viable method for teaching ultrasound (US)-guided breast biopsy of palpable breast lesions. Third-year medical students were assessed both preinstruction and postinstruction on their ability to perform US-guided needle aspiration or biopsy of artificially created masses using a 10-item checklist. Forty-one third-year medical students completed the cadaver laboratory as part of the surgery clerkship. Eight items on the checklist were found to be significantly different between pre-testing and post-testing. The mean preinstruction score was 2.4, whereas the mean postinstruction score was 7.10 (P cadaver models have been widely used in medical education. However, there are few fresh cadaver models that provide instruction on procedures done in the outpatient setting. Our model was found to be an effective method for the instruction of US-guided breast biopsy among medical students. Copyright © 2016 Elsevier Inc. All rights reserved.

    2016-05-01

    Health care and academic systems are increasingly collaborating with community health advisors (CHAs) to provide culturally relevant health interventions that promote sustained community transformation. Little attention has been placed on CHA training evaluation, including core competency attainment. This study identified common CHA core competencies, generated a theoretically based measure of those competencies, and explored psychometric properties of that measure. A concept synthesis revealed five CHA core competencies (leadership, translation, guidance, advocacy, and caring). The CHA Core Competency Retrospective Pretest/Posttest (CCCRP) resulted from that synthesis, which was administered using multiple approaches to individuals who previously received CHA training (N= 142). Exploratory factor analyses revealed a two-factor structure underlying the posttraining data, and Cronbach's alpha indicated high internal consistency. This study suggested some CHA core competencies might be more interrelated than previously thought, and two major competencies exist rather than five and supported the CCCRP's use to evaluate core competency attainment resulting from training. © The Author(s) 2014.

    Critical care nurses process vast amounts of information and require well developed critical-thinking skills to make clinical decisions. Using a pretest posttest design, the critical-thinking skills of 31 postgraduate nurses were evaluated using the California Critical Thinking Skills Test (CCTST). For the total group, mean critical-thinking scores improved slightly over time. The CCTST revealed a mean pretest score of 18.5 and a mean posttest score of 19.7, both of which were higher than the established norms for the test. Overall, no significant difference was observed between pretest and posttest. However, statistical significance was observed posttest for nurses whose critical-thinking scores improved (p critical-thinking skills during the course of their study.

    Factors previously shown to influence patient care include effective decision making, team work, evidence based practice, staffing and job satisfaction. Clinical rounds have the potential to optimise these factors and impact on patient outcomes, but use of this strategy by intensive care nurses has not been reported. To determine the effect of implementing Nursing Rounds in the intensive care environment on patient care planning and nurses' perceptions of the practice environment and work satisfaction. Pre-test post-test 2 group comparative design. Two intensive care units in tertiary teaching hospitals in Australia. A convenience sample of registered nurses (n=244) working full time or part time in the participating intensive care units. Nurses in participating intensive care units were asked to complete the Practice Environment Scale-Nursing Work Index (PES-NWI) and the Nursing Worklife Satisfaction Scale (NWSS) prior to and after a 12 month period during which regular Nursing Rounds were conducted in the intervention unit. Issues raised during Nursing Rounds were described and categorised. The characteristics of the sample and scale scores were summarised with differences between pre and post scores analysed using t-tests for continuous variables and chi-square tests for categorical variables. Independent predictors of the PES-NWI were determined using multivariate linear regression. Nursing Rounds resulted in 577 changes being initiated for 171 patients reviewed; these changes related to the physical, psychological--individual, psychological--family, or professional practice aspects of care. Total PES-NWI and NWSS scores were similar before and after the study period in both participating units. The NWSS sub-scale of interaction between nurses improved in the intervention unit during the study period (pre--4.85±0.93; post--5.36±0.89, p=0.002) with no significant increase in the control group. Factors independently related to higher PES-NWI included

    Hypertension is known to have high rates among Chinese Americans. Identifying culturally specific interventions to reduce sedentary behavior may be effective in reducing hypertension. This study examines the effects of an 8-week walking program with and without cultural modification. The study used a 2-group, pretest and posttest, quasi-experimental design. A total sample of 128 Chinese American immigrants with hypertension were assigned to walking groups. The results showed that the walking program had no significant effects upon participant blood pressure or walking endurance. The results also revealed that individuals in the maintenance stage walked longer than those in the preparation stage. A comparison of demographic data showed that subjects with a lower level of education walked more minutes per week, which contributed to lower systolic blood pressures among this group as compared with those with a higher level of education. These results suggest that this walking protocol, when translated into Chinese and when accompanied by a weekly telephone reminder and other interactions with a Chinese-speaking nurse, is appropriate to use without additional cultural modification. Future research should examine other components of Chinese culture or should apply this protocol for a longer period of time.

    This quantitative, quasi-experimental research investigated if two instructional approaches, the Emporium Computer-Based (Group 2) versus the hands-on approach (Group 1), resulted any difference in student achievement in science for four-year-old prekindergarten students at a private childcare facility in North Carolina. Three research questions hypothesized these relationships: (a) Group 2 versus Group 1 assessed student achievement as theoretically based on Piaget and Vygotsky's perspectives of child development, (b) the instructional approaches related to gender, and (c) the instructional approaches interrelated to ethnicity. Using a two-factor ANOVA and ANCOVA techniques, involved a convenience sample of 126 four-year-old prekindergarten students of which a convenience sample of 126 participated. The Assessment of Measurements for Pre-K (AMP-K), pretest and posttest scores of each group of 63 students measured student achievement. The t tests determined if a significant difference in student achievement existed (dependent variable) with the Emporium Computer-Based versus hands-on instructional approaches (independent variables). The posttest scores of Group 2 (p = 0.00), indicated a significant difference in student achievement. However, gender and ethnicity variables had no effect on student achievement, male (M = 36.14, SD = 19.61) and female (M = 42.91, SD = 18.99) with (p = 0.49), and ethnicity resulted, F (1,125) = 1.65, (p = 0.20). These results suggested that further research on the Emporium Computer-Based instructional approach could improve students' intellectual abilities through more innovative practices.

    Mental health complaints are quite common in health care employees and can have adverse effects on work functioning. The aim of this study was to evaluate an e-mental health (EMH) approach to workers' health surveillance (WHS) for nurses and allied health professionals. Using the waiting-list group of a previous randomized controlled trial with high dropout and low compliance to the intervention, we studied the pre- and posteffects of the EMH approach in a larger group of participants. We applied a pretest-posttest study design. The WHS consisted of online screening on impaired work functioning and mental health followed by online automatically generated personalized feedback, online tailored advice, and access to self-help EMH interventions. The effects on work functioning, stress, and work-related fatigue after 3 months were analyzed using paired t tests and effect sizes. One hundred and twenty-eight nurses and allied health professionals participated at pretest as well as posttest. Significant improvements were found on work functioning (p = 0.01) and work-related fatigue (p Work functioning had relevantly improved in 30% of participants. A small meaningful effect on stress was found (Cohen d = .23) in the participants who had logged onto an EMH intervention (20%, n = 26). The EMH approach to WHS improves the work functioning and mental health of nurses and allied health professionals. However, because we found small effects and participation in the offered EMH interventions was low, there is ample room for improvement.

    This report presents selected results of posttest RELAP4 modeling of LOFT loss-of-coolant experiment L1-3A, a double-ended isothermal cold leg break with lower plenum emergency core coolant injection. Comparisons are presented between the pretest prediction, the posttest analysis, and the experimental data. It is concluded that pressurizer modeling is important for accurately predicting system behavior during the initial portion of saturated blowdown. Using measured initial conditions rather than nominal specified initial conditions did not influence the system model results significantly. Using finer nodalization in the reactor vessel improved the prediction of the system pressure history by minimizing steam condensation effects. Unequal steam condensation between the downcomer and core volumes appear to cause the manometer oscillations observed in both the pretest and posttest RELAP4 analysis

    Full Text Available When lay jurors are unfamiliar with key evidentiary issues, expert evidence, judicial instructions and group deliberation may enhance their understanding of this evidence. Systematic steps to assess the relationship between juror biases in cases of child sexual abuse are offered as an example to illustrate a programmatic research approach. Using pretest-posttest research designs, the effectiveness of three traditional legal procedural safeguards to reduce common jury misconceptions in the context of simulated trials were tested and compared. By measuring mock-juror knowledge before and after each intervention, knowledge gains attributable to these interventions were distinguished from practice effects. Unexpected increases in acquittals following deliberation underscored the importance of adding adequate control groups and of testing deliberation effects in jury simulation studies. Benefits of this research paradigm to assist courts, legal counsel and policy makers in devising effective methods to enhance jury decisions in complex criminal cases are discussed. Cuando los miembros del jurado popular no están familiarizados con los temas probatorios clave, las pruebas periciales, las instrucciones judiciales y la deliberación de grupo pueden mejorar su comprensión de las evidencias.

    Full Text Available Background: Motherhood is a transformative and pleasing experience in a woman’s life. However, given the physical and psychological changes, it can induce a degree of stress and anxiety in mothers. The aim of the present study was to evaluate the effects of cognitive-behavioral stress management (CBSM on maternal anxiety and depression during pregnancy and newborns’ Apgar scores. Methods: This semi-experimental study was performed by applying a pretest-posttest control-group design. Overall, 30 primiparous mothers were selected among women referring to health clinics of Kerman, Iran, using convenience sampling. Subjects were randomly allocated to experimental and control groups. Data were collected, using Pregnancy-Related Anxiety Questionnaire and Edinburgh Postnatal Depression Questionnaire. After completing the pretest, the experimental group was subjected to 12 sessions of CBSM training; posttest data were collected after the intervention. Multivariate analysis of covariance was performed, using SPSS version 16. P-value < 0.05 was considered statistically significant. Results: The obtained results revealed a significant decrement in the average posttest scores of anxiety and depression in the experimental group, compared to pretest scores and the control group. Moreover, differences in 1- and 5-minute Apgar scores between the two groups were statistically significant. These findings indicated the effectiveness of CBSM during pregnancy in reducing maternal anxiety and depression. Conclusion: Pregnant women can benefit from psychological interventions such as CBSM in medical and health care centers.

    We evaluated feasibility of the Internet-based Relieve Children's Pain (RCP) protocol to improve nurses' management of children's pain. RCP is an interactive, content-focused, and Kolb's experiential learning theory-based intervention. Using a one-group, pretest-posttest design, we evaluated feasibility of RCP and pretest-posttest difference in scores for nurses' beliefs, and simulated and actual pain management practices. Twenty-four RNs completed an Internet-based Pain Beliefs and Practices Questionnaire (PBPQ, alpha=.83) before and after they completed the RCP and an Acceptability Scale afterward. Mean total PBPQ scores significantly improved from pretest to posttest as did simulated practice scores. After RCP in actual hospital practice, nurses administered significantly more ibuprofen and ketorolac and children's pain intensity significantly decreased. Findings showed strong evidence for the feasibility of RCP and study procedures and significant improvement in nurses' beliefs and pain management practices. The 2-hr RCP program is promising and warrants replication with an attention control group and a larger sample.

    Measuring quality of care is essential to improve primary care. Quality of primary care for patients is usually assessed by patient satisfaction questionnaires. However, patients may not be able to judge quality of care without also reflecting their perception of the environment. We determined the effect that redesigning a primary care office had on patient satisfaction. We hypothesized that renovating the interior would make patients more satisfied with the quality of medical care. We performed a Pretest-Posttest analysis in a recently renovated single-practice primary care office in Grenchen, Switzerland. Before and after renovation, we distributed a questionnaire to assess patient satisfaction in four domains. We chose a Likert scale (1 = very poor to 6 = very good), and 12 quality indicators, and included two consecutive samples of patients presenting at the primary care office before (n = 153) and after (n = 153) interior design renovation. Response rate was high (overall 85 %). The sample was similar to the enlisted patient collective, but the sample population was older (60 years) than the collective (52 years). Patient satisfaction was higher for all domains after the office was renovated (p patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care. These biases should be taken into account when quality assessment instruments are designed for patients.

    Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being such as work engagement. This study examined the effectiveness of a newly developed job crafting intervention program on work engagement (as primary outcome), as well as job crafting and psychological distress (as secondary outcomes), using a pretest-posttest study design among Japanese employees. Participants were managers of a private company and a private psychiatric hospital in Japan. The job crafting intervention program consisted of two 120-min sessions with a two-week interval between them. Outcomes were assessed at baseline (Time 1), post-intervention (Time 2), and a one-month follow-up (Time 3). The mixed growth model analyses were conducted using time (Time 1, Time 2, and Time 3) as an indicator of intervention effect. Effect sizes were calculated using Cohen's d. The program showed a significant positive effect on work engagement (t = 2.20, p = 0.03) in the mixed growth model analyses, but with only small effect sizes (Cohen's d = 0.33 at Time 2 and 0.26 at Time 3). The program also significantly improved job crafting (t = 2.36, p = 0.02: Cohen's d = 0.36 at Time 2 and 0.47 at Time 3) and reduced psychological distress (t = -2.06, p = 0.04: Cohen's d = -0.15 at Time 2 and -0.31 at Time 3). The study indicated that the newly developed job crafting intervention program was effective in increasing work engagement, as well as in improving job crafting and decreasing psychological distress, among Japanese managers.

    This study examined the effects of GeoGebra on mathematics performance of students with different spatial visualization. A qusai-experimental, pretest-posttest control group design was conducted. A total of 71 students from two intact groups were involved in the study. They were in two groups and each group was randonly assigned to the experimental group (36 students) and control group (35 students). A spatial visual test to identify students with high or low visualization, and a mathematics performance pre-test were administered at the initial stage of this study. A post-test was administered after 12 weeks of treatment using GeoGebra. Analyses of Covarion (ANCOVA) was used to adjust for the pre-test score. Findings showed that the group with access to GeoGebra achieved significantly better test scores in the posttest as compared to the group which followed the traditional teaching method. A two-way ANCOVA used to analyse the effect of students' spatial visualization on post-test performance showed that there was no effect. The results from this study suggested that using GeoGebra had helped the students to score better in the posttest. However, there is no significance difference on mathematics performances on students with difference types of spatial visualisastion. This study indicates that GeoGebra is useful in enhancing the teaching and learning of mathematics.

    Isik, Hakan

    This study is premised on the fact that student conceptions of optics appear to be unrelated to student characteristics of gender, age, years since high school graduation, or previous academic experiences. This study investigated the relationships between student characteristics and student performance on image formation test items and the changes in student conceptions of optics after an introductory inquiry-based physics course. Data was collected from 39 college students who were involved in an inquiry-based physics course teaching topics of geometrical optics. Student data concerning characteristics and previous experiences with optics and mathematics were collected. Assessment of student understanding of optics knowledge for pinholes, plane mirrors, refraction, and convex lenses was collected with, the Test of Image Formation with Light-Ray Tracing instrument. Total scale and subscale scores representing the optics instrument content were derived from student pretest and posttest responses. The types of knowledge, needed to answer each optics item correctly, were categorized as situational, conceptual, procedural, and strategic knowledge. These types of knowledge were associated with student correct and incorrect responses to each item to explain the existences and changes in student scientific and naive conceptions. Correlation and stepwise multiple regression analyses were conducted to identify the student characteristics and academic experiences that significantly predicted scores on the subscales of the test. The results showed that student experience with calculus was a significant predictor of student performance on the total scale as well as on the refraction subscale of the Test of Image Formation with Light-Ray Tracing. A combination of student age and previous academic experience with precalculus was a significant predictor of student performance on the pretest pinhole subscale.

    The Nuclear Power Engineering Corporation (NUPEC) of Japan and the U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, co-sponsored a Cooperative Containment Research Program at Sandia National Laboratories (SNL) in Albuquerque, New Mexico. As part of the program, a prestressed concrete containment vessel (PCCV) model was subjected to a series of overpressurization tests at SNL beginning in July 2000 and culminating in a functional failure mode or Limit State Test (LST) in September 2000 and a Structural Failure Mode Test (SFMT) in November 2001. The PCCV model, uniformly scaled at 1:4, is representative of the containment structure of an actual Pressurized Water Reactor (PWR) plant (OHI-3) in Japan. The objectives of the pressurization tests were to obtain measurement of the structural response to pressure loading beyond design basis accident in order to validate analytical modeling, to find pressure capacity of the model, and to observe its failure mechanisms. This paper compares results of pretest analytical studies of the PCCV model to the PCCV high pressure test measurements and describes results of post-test analytical studies. These analyses have been performed by ANATECH Corp. under contract with Sandia National Laboratories. The post-test analysis represents the third phase of a comprehensive PCCV analysis effort. The first phase consisted of preliminary analyses to determine what finite element models would be necessary for the pretest prediction analyses, and the second phase consisted of the pretest prediction analyses. The principal objectives of the post-test analyses were: (1) to provide insights to improve the analytical methods for predicting the structural response and failure modes of a prestressed concrete containment, and (2) to evaluate by analysis any phenomena or failure mode observed during the test that had not been explicitly predicted by analysis. In addition to summarizing comparisons between measured

    Science education must be a priority for citizens to function and be productive in a global, technological society. African Americans receive fewer science degrees in proportion to the Caucasian population. The primary purposes of this study were to determine the difference between the pretest and posttest science self-efficacy scores of African-American nonscience majors, the difference between the pretest and posttest science self-efficacy scores of African-American science majors, the relationship between science self-efficacy and course grade, the relationship between gender and science self-efficacy score, and the relationship between science self-efficacy score and course withdrawal. This study utilized a Likert survey instrument. All participants were enrolled in freshman level courses in the physical sciences at a historically black institution: a college or university. Participants completed the pretest survey within two weeks after the 12th class day of the semester. Initially, 458 participants completed the pretest survey. The posttest was administered within two weeks before the final exam. Only 245 participants completed the posttest survey. Results indicate that there is a difference in science self-efficacy of science majors and nonscience majors. There was no significant difference between the pretest and posttest science self-efficacy scores of African-American science majors and nonscience majors. There was no significant relationship between science self-efficacy and course grade, gender and science self-efficacy score, and course withdrawal and science self-efficacy score.

    Context Female sexual pain and dysfunction Objective To evaluate the effectiveness of a new site-specific, manual soft-tissue therapy in increasing orgasm and reducing dyspareunia (painful intercourse) in women with histories indicating abdominopelvic adhesion formation. Design and Intervention A total of 29 new patients presenting with infertility or abdominopelvic pain-related problems, and also indicating sexual pain or dysfunction, received a series of treatments (mean, 19.5 hours) designed to address biomechanical dysfunction and restricted mobility due to adhesions affecting the reproductive organs and adjacent structures. Outcome Measures Primary outcome measures were post-test vs pretest scores on: (1) the Female Sexual Function Index (FSFI) full scale, orgasm domain, and pain domain; and (2) 3 supplemental 10-point rating scales of sexual pain levels. Secondary outcome measures were post-test vs pretest scores in the other 4 FSFI domains (desire, arousal, lubrication, and satisfaction). The Wilcoxon signed-rank test was used for all statistical analyses. Results For the 23 patients available for follow-up, the paired FSFI post-test vs pretest scores were significant (P ≤ .003) on all measures. Of the 17 patients who completed the 3 sexual pain scales, the paired post-test vs pretest scores were significant (P ≤ .002) Conclusions Many cases of inhibited orgasm, dyspareunia, and other aspects of sexual dysfunction seem to be treatable by a distinctive, noninvasive manual therapy with no risks and few, if any, adverse effects. The therapy should be considered a new adjunct to existing gynecologic and medical treatments. PMID:15775874

    This study examined whether an online course would lead to increased knowledge about the medical issues volunteers encounter during a marathon. Health care professionals who volunteered to provide medical coverage for an annual marathon were eligible for the study. Demographic information about medical volunteers including profession, specialty, education level and number of marathons they had volunteered for was collected. A 15-question test about the most commonly encountered medical issues was created by the authors and administered before and after the volunteers took the online educational course and compared to a pilot study the previous year. Seventy-four subjects completed the pre-test. Those who participated in the pilot study last year (N = 15) had pre-test scores that were an average of 2.4 points higher than those who did not (mean ranks: pilot study = 51.6 vs. non-pilot = 33.9, p = 0.004). Of the 74 subjects who completed the pre-test, 54 also completed the post-test. The overall post-pre mean score difference was 3.8 ± 2.7 (t = 10.5 df = 53 p online education demonstrated a long-term (one-year) increase in test scores. Testing also continued to show short-term improvement in post-course test scores, compared to pre-course test scores. In general, marathon medical volunteers who had no volunteer experience demonstrated greater improvement than those who had prior volunteer experience.

    Prior studies have evaluated only the prolonged use of cryotherapy as a nonpharmacologic pain intervention. The purpose of this study was to determine whether a 30-minute application of cryotherapy at the time pain medication was given after a total knee arthroplasty (TKA) provided better pain relief than analgesic drugs alone. A pretest, posttest, randomized controlled trial study design with crossover was used to evaluate the effects of cryotherapy on postoperative pain and satisfaction with pain management. A convenience sample of postoperative knee replacement patients constituted participants in the study. Two sequential episodes of pain requiring analgesic administration were studied in each patient, one with a 30-minute cryotherapy application and the other without cryotherapy. Dependent variables were changes in pain (posttest minus pretest) and level of satisfaction with pain management. Data were analyzed with repeated-measures analysis of variance, with p cryotherapy administration for the other pain episode. No significant difference between the two treatments was found for changes in pain scores after the treatments or patient satisfaction with pain management (p > .05). The order in which the treatments were provided was found to be significant (p = .02) for scores on patient satisfaction with pain management, with cryotherapy as the treatment for the second pain episode having higher scores than when delivered for the first pain episode. Sixty minutes after analgesic administration with or without cryotherapy, average pain scores remained greater than 7. In TKA patients, the short-term application of cryotherapy with analgesic medication administration did not significantly decrease pain or improve patient satisfaction with pain management compared with analgesic medication administration only. Further study is necessary to determine whether short-term cryotherapy shortly after TKA is of benefit to pain relief and patient satisfaction.

    It is unclear whether propensity score analysis (PSA) based on pretest and demographic covariates will meet the ignorability assumption for replicating the results of randomized experiments. This study applies within-study comparisons to assess whether pre-Kindergarten (pre-K) treatment effects on achievement outcomes estimated using PSA based on a pretest and demographic covariates can approximate those found in a randomized experiment. Data-Four studies with samples of pre-K children each provided data on two math achievement outcome measures with baseline pretests and child demographic variables that included race, gender, age, language spoken at home, and mother's highest education. Research Design and Data Analysis-A randomized study of a pre-K math curriculum provided benchmark estimates of effects on achievement measures. Comparison samples from other pre-K studies were then substituted for the original randomized control and the effects were reestimated using PSA. The correspondence was evaluated using multiple criteria. The effect estimates using PSA were in the same direction as the benchmark estimates, had similar but not identical statistical significance, and did not differ from the benchmarks at statistically significant levels. However, the magnitude of the effect sizes differed and displayed both absolute and relative bias larger than required to show statistical equivalence with formal tests, but those results were not definitive because of the limited statistical power. We conclude that treatment effect estimates based on a single pretest and demographic covariates in PSA correspond to those from a randomized experiment on the most general criteria for equivalence.

    This quantitative research study used a pretest/posttest design and reviewed how an educational electronic documentation system helped nursing students to identify the accurate "related to" statement of the nursing diagnosis for the patient in the case study. Students in the sample population were senior nursing students in a bachelor of science nursing program in the northeastern United States. Two distinct groups were used for a control and intervention group. The intervention group used the educational electronic documentation system for three class assignments. Both groups were given a pretest and posttest case study. The Accuracy Tool was used to score the students' responses to the related to statement of a nursing diagnosis given at the end of the case study. The scores of the Accuracy Tool were analyzed, and then the numeric scores were placed in SPSS, and the paired t test scores were analyzed for statistical significance. The intervention group's scores were statistically different from the pretest scores to posttest scores, while the control group's scores remained the same from pretest to posttest. The recommendation to nursing education is to use the educational electronic documentation system as a teaching pedagogy to help nursing students prepare for nursing practice. © 2014 NANDA International, Inc.

    This study offers evidence that computer-based training is an effective tool for teaching nursing facility managers about ergonomics and increasing their awareness of potential problems. Study participants (N = 45) were randomly assigned into a treatment or control group. The treatment group completed the ergonomics training and a pre- and posttest. The control group completed the pre- and posttests without training. Treatment group participants improved significantly from 67% on the pretest to 91% on the posttest, a gain of 24%. Differences between mean scores for the control group were not significant for the total score or for any of the subtests.

    Reactions to contrast material are uncommon in diagnostic radiology, and vary in clinical presentation from urticaria to life-threatening anaphylaxis. Prior studies have demonstrated a high error rate in contrast reaction management, with smaller studies using simulation demonstrating variable data on effectiveness. We sought to assess the effectiveness of high-fidelity simulation in teaching contrast reaction management for residents, fellows, and attendings. A 20-question multiple-choice test assessing contrast reaction knowledge, with Likert-scale questions assessing subjective comfort levels of management of contrast reactions, was created. Three simulation scenarios that represented a moderate reaction, a severe reaction, and a contrast reaction mimic were completed in a one-hour period in a simulation laboratory. All participants completed a pretest and a posttest at one month. A six-month delayed posttest was given, but was optional for all participants. A total of 150 radiologists participated (residents = 52; fellows = 24; faculty = 74) in the pretest and posttest; and 105 participants completed the delayed posttest (residents = 31; fellows = 17; faculty = 57). A statistically significant increase was found in the one-month posttest (P < .00001) and the six-month posttest scores (P < .00001) and Likert scores (P < .001) assessing comfort level in managing all contrast reactions, compared with the pretest. Test scores and comfort level for moderate and severe reactions significantly decreased at six months, compared with the one-month posttest (P < .05). High-fidelity simulation is an effective learning tool, allowing practice of "high-acuity" situation management in a nonthreatening environment; the simulation training resulted in significant improvement in test scores, as well as an increase in subjective comfort in management of reactions, across all levels of training. A six-month refresher course is suggested, to maintain knowledge and comfort level in

    Young, Jerry Wayne

    The purpose of this study was to determine the effects of four instructional methods (direct instruction, computer-aided instruction, video observation, and microcomputer-based lab activities), gender, and time of testing (pretest, immediate posttest for determining the immediate effect of instruction, and a delayed posttest two weeks later to determine the retained effect of the instruction) on the achievement of sixth graders who were learning to interpret graphs of displacement and velocity. The dependent variable of achievement was reflected in the scores earned by students on a testing instrument of established validity and reliability. The 107 students participating in the study were divided by gender and were then randomly assigned to the four treatment groups, each taught by a different teacher. Each group had approximately equal numbers of males and females. The students were pretested and then involved in two class periods of the instructional method which was unique to their group. Immediately following treatment they were posttested and two weeks later they were posttested again. The data in the form of test scores were analyzed with a two-way split-plot analysis of variance to determine if there was significant interaction among technique, gender, and time of testing. When significant interaction was indicated, the Tukey HSD test was used to determine specific mean differences. The results of the analysis indicated no gender effect. Only students in the direct instruction group and the microcomputer-based laboratory group had significantly higher posttest-1 scores than pretest scores. They also had significantly higher posttest-2 scores than pretest scores. This suggests that the learning was retained. The other groups experienced no significant differences among pretest, posttest-1, and posttest-2 scores.

    Full Text Available Abstract Background The coronary artery calcium (CAC score is an independent predictor of coronary heart disease. We sought to combine information from the CAC score with information from conventional cardiac risk factors to produce post-test risk estimates, and to determine whether the score may add clinically useful information. Methods We measured the independent cross-sectional associations between conventional cardiac risk factors and the CAC score among asymptomatic persons referred for non-contrast electron beam computed tomography. Using the resulting multivariable models and published CAC score-specific relative risk estimates, we estimated post-test coronary heart disease risk in a number of different scenarios. Results Among 9341 asymptomatic study participants (age 35–88 years, 40% female, we found that conventional coronary heart disease risk factors including age, male sex, self-reported hypertension, diabetes and high cholesterol were independent predictors of the CAC score, and we used the resulting multivariable models for predicting post-test risk in a variety of scenarios. Our models predicted, for example, that a 60-year-old non-smoking non-diabetic women with hypertension and high cholesterol would have a 47% chance of having a CAC score of zero, reducing her 10-year risk estimate from 15% (per Framingham to 6–9%; if her score were over 100, however (a 17% chance, her risk estimate would be markedly higher (25–51% in 10 years. In low risk scenarios, the CAC score is very likely to be zero or low, and unlikely to change management. Conclusion Combining information from the CAC score with information from conventional risk factors can change assessment of coronary heart disease risk to an extent that may be clinically important, especially when the pre-test 10-year risk estimate is intermediate. The attached spreadsheet makes these calculations easy.

    measured self-reported student behaviours and preferences concerning the online modules. Two focus groups were convened after all posttest surveys were completed to gather qualitative data about student preferences. Main Results – Of the 252 volunteers, 239 students (57.9% of enrolled students completed both the pretest and the posttest, 89 filled out the follow-up survey, and 7 students participated in a focus group. Students used the online module content differently; accordingly those numbers were not reported. Researchers compared pretest and posttest scores to find that the posttest scores were significantly higher than the pretest scores (p < 0.001. Of 239 pretest and posttest pairs evaluated, the mean pretest score was 10.456 and the mean posttest score was 13.843. A t-test survey and focus group data evaluated student perceptions of the module. Students reported a slight preference for online instruction. Conclusion – After completing an online library module, students’ performance on information literacy skills tests improved from the pretest to the posttest. Focus group and survey data indicate a slight student preference for online tutorials over in-person instruction. Although intended as a blended approach to library instruction, the voluntary in-person instruction was not well attended and has subsequently been changed to mandatory in-class instruction. The authors recommend further research to evaluate how the medium and format of instruction impacts student learning outcomes.

    To evaluate the baseline knowledge and knowledge gained of nurses, nursing students, midwives, and nurse practitioners who completed Breastfeeding Basics, an online educational program. This study reports on an anonymous evaluation of an online breastfeeding education program developed and maintained to promote evidence-based breastfeeding practice. Included in the study were 3736 nurses, 728 nurse practitioners/midwives, and 3106 nursing students from the United States who completed ≥ one pretest or posttest on the Breastfeeding Basics website between April 1999 and December 31, 2011. Baseline scores were analyzed to determine if nurses' baseline knowledge varied by selected demographic variables such as age, gender, professional level, personal or partner breastfeeding experience, and whether they were required to complete the website for a job or school requirement and to determine knowledge gaps. Pretest and posttest scores on all modules and in specific questions with low pretest scores were compared as a measure of knowledge gained. Lower median pretest scores were found in student nurses (71%), males (71%), those required to take the course (75%), and those without personal breastfeeding experience (72%). The modules with the lowest median pretest scores were Anatomy/Physiology (67%), Growth and Development of the Breastfed Infant (67%), the Breastfeeding Couple (73%), and the Term Infant with Problems (60%). Posttest scores in all modules increased significantly (p nurses and nursing students. Gaps exist in nurses' breastfeeding knowledge.

    To investigate the effect of the implementation of a patient and family education programme for pressure ulcer prevention in an organisation for home care nursing on guideline adherence and on prevalence and severity of pressure ulcers and to examine the determining factors for the application of measures for pressure ulcer prevention. Quality improvement programmes in pressure ulcer prevention are not always successful. Implementation study using a pretest-post-test design. Data were collected in three probability samples. The first post-test data collection was held after six months, the second after 18 months. Statistical analysis was used, comparing the pretest sample and the second post-test sample. After 18 months, the proportion of subjects with adherent measures had increased from 10·4-13·9%, the proportion of subjects with non-adherent measures decreased from 45·7-36·0%, the proportion of subjects without pressure ulcer prevention increased from 43·9-50·1% (ppressure ulcer prevalence and less severe skin lesions. The nurses' judgement of a patient risk status was the most important factor for applying preventive measures. Furthermore, application of pressure ulcer prevention was determined by higher age (from the age category of 70-79 years), higher dependency for the activities of daily living, higher than baseline mobility score and the presence of a pressure ulcer. Guideline adherence in pressure ulcer prevention changed significantly after implementation of the education programme. There might have been inconsistencies in the nurses' risk judgement. Quality of pressure ulcer prevention improved, but several items for improvement remain. Adaptation of risk assessment procedures is needed. © 2010 Blackwell Publishing Ltd.

    Objective. To examine whether playing a board game can assist PharmD students in learning autonomic nervous system (ANS) pharmacology. Design. Of 72 students enrolled in a required second-year pharmacology course, 22 students volunteered to play the board game, which was followed by an in-class examination consisting of 42 ANS questions (ANSQs) and 8 control questions (CTLQs). Participants were given a pretest and a posttest to assess immediate educational improvement. Participants' scores for pretest, posttest, in-class examination, and ANSQs were compared. Also, scores for examination, ANSQs, and CTLQs were compared between board game participants (PART) and nonparticipating classmates (NPART). Assessment. Board game participants scored progressively higher between the pretest, posttest, examination, and ANSQs. Additionally, PART scores were higher than NPART scores for examination and ANSQs. Difference between PART and NPART CTLQ scores was not significant. Conclusion. A board game can assist PharmD students in learning ANS pharmacology.

  12. Opportunity to learn: Investigating possible predictors for pre-course Test Of Astronomy STandards TOAST scores

    Berryhill, Katie J.

    As astronomy education researchers become more interested in experimentally testing innovative teaching strategies to enhance learning in introductory astronomy survey courses ("ASTRO 101"), scholars are placing increased attention toward better understanding factors impacting student gain scores on the widely used Test Of Astronomy STandards (TOAST). Usually used in a pre-test and post-test research design, one might naturally assume that the pre-course differences observed between high- and low-scoring college students might be due in large part to their pre-existing motivation, interest, experience in science, and attitudes about astronomy. To explore this notion, 11 non-science majoring undergraduates taking ASTRO 101 at west coast community colleges were interviewed in the first few weeks of the course to better understand students' pre-existing affect toward learning astronomy with an eye toward predicting student success. In answering this question, we hope to contribute to our understanding of the incoming knowledge of students taking undergraduate introductory astronomy classes, but also gain insight into how faculty can best meet those students' needs and assist them in achieving success. Perhaps surprisingly, there was only weak correlation between students' motivation toward learning astronomy and their pre-test scores. Instead, the most fruitful predictor of TOAST pre-test scores was the quantity of pre-existing, informal, self-directed astronomy learning experiences.

    Delirium is a common and serious complication of hospitalisation in older adults. It can lead to prolonged hospital stay, institutionalisation, and even death. However, it often remains unrecognised or is not managed adequately. The aim of this study was to evaluate the effects of an educational intervention for nursing staff on three aspects of clinical practice concerning delirium in older hospitalised patients: the frequency and correctness of screening for delirium using the 13-item Delirium Observation Screening score (DOS), and the frequency of geriatric consultations requested for older patients. The a priori expectations were that there would be an increase in all three of these outcomes. We designed an educational intervention and implemented this on two inpatient hospital units. Before providing the educational session, the nursing staff was asked to fill out two questionnaires about delirium in older hospitalised patients. The educational session was then tailored to each unit based on the results of these questionnaires. Additionally, posters and flyers with information on the screening and management of delirium were provided and participants were shown where to find additional information. Relevant data (outcomes, demographics and background patient data) were collected retrospectively from digital medical files. Data was retrospectively collected for four different time points: three pre-test and one post-test. There was a significant increase in frequency of delirium screening (P = 0.001), and both units showed an increase in the correctness of the screening. No significant effect of the educational intervention was found for the proportion of patients who received a geriatric consultation (P = 0.083). The educational intervention was fairly successful in making positive changes in clinical practice: after the educational session an improvement in the frequency and correctness of screening for delirium was observed.

    contrast. Logistic regression models were used to evaluate the association between individual characteristics and contrast use. An 11-point score was derived from the significant characteristics. Results. Variables associated with microbubble use were age, sex, smoking, presence of multiple risk factors, bodymass index (BMI, referral for dobutamine stress echocardiography, history of coronary artery disease, and abnormal baseline electrocardiogram. All variables except BMI were given a score of 1 if present and 0 if absent; BMI was given a score of 0 to 4 according to its value. An increased score was directly proportional to increased likelihood of contrast use. The score cutoff value to optimize sensitivity and specificity was 5. Conclusions. A pretest score can be computed from information available before imaging. It may facilitate contrast agent use through early identification of patients who are likely to benefit from improved endocardial border definition.

    Job stress is a part of nurses' professional life that causes the decrease of the nurses' job satisfaction and quality of work life. This study aimed to determine the effect of positive thinking via social media applications on the nurses' quality of work life. This was a pretest-posttest quasi-experimental study design with a control group. The samples were selected among the nurses in two hospitals in Fasa University of Medical Sciences and divided randomly into two interventional ( n = 50) and control ( n = 50) groups. Positive thinking training through telegrams was sent to the intervention group during a period of 3 months. Data were collected by using Brooks and Anderson's questionnaire of work life quality and analyzed by SPSS 18. The mean total scores of pretest and posttest in the intervention group improved noticeably and there were significant differences between mean scores of quality of work life in pretest and posttest scores in interventional groups ( p work life quality, home life ( p work design ( p work context ( p work world ( p = 0.003). This study concluded that positive thinking training via social media application enhanced nurses' quality of work life. This study is necessary to carry out on a larger sample size for generalizing findings better.

    Epidemiological data demonstrate the need for lower-extremity injury-prevention training. Neuromuscular-control (NMC) programs are immediately effective at minimizing lower-extremity injury risk and improving sport-related performance measures. Research investigating lasting effects after an injury-prevention program is limited. To determine whether dynamic balance, landing mechanics, and hamstring and quadriceps strength could be improved after a 6-wk NMC intervention and maintained for a season. Prospective case series. Controlled laboratory. 11 Division I women's basketball players (age 19.40 ± 1.35 y, height 178.05 ± 7.52 cm, mass 72.86 ± 10.70 kg). Subjects underwent testing 3 times, completing the Star Excursion Balance Test (SEBT), Landing Error Scoring System (LESS), and isometric strength testing for the hamstrings and quadriceps muscles. Pretest and posttest 1 occurred immediately before and after the intervention, respectively, and posttest 2 at the end of the competitive season, 9 mo after posttest 1. Subjects participated in eighteen 30-min plyometric and NMC-training sessions over a 6-wk period. The normalized SEBT composite score, normalized peak isometric hamstrings:quadriceps (H:Q) ratio, and the LESS total score. The mean composite reach significantly improved over time (F2,10 = 6.96, P = .005) where both posttest scores were significantly higher than pretest (70.41% ± 4.08%) (posttest 1 73.48% ± 4.19%, t10 = -3.11, P = .011) and posttest 2 (74.2% ± 4.77%, t10 = -3.78, P = .004). LESS scores significantly improved over time (F2,10 = 6.29, P = .009). The pretest LESS score (7.30 ± 3.40) was higher than posttest 1 (4.9 ± 1.20, t10 = 2.71, P = .024) and posttest 2 (5.44 ± 1.83, t10 = 2.58, P = .030). There were no statistically significant differences (P > .05) over time for the H:Q ratio when averaging both legs (F2,10 = 0.83, P = .45). A 6-wk NMC program improved landing mechanics and dynamic balance over a 9-mo period in women

    Inherent safety tests were performed during 1986 in the 400-MW (thermal) Fast Flux Test Facility (FFTF) reactor to demonstrate the effectiveness of an inherent shutdown device called the gas expansion module (GEM). The GEM device provided a strong negative reactivity feedback during loss-of-flow conditions by increasing the neutron leakage as a result of an expanding gas bubble. The best-estimate pretest calculations for these tests were performed using the IANUS plant analysis code (Westinghouse Electric Corporation proprietary code) and the MELT/SIEX3 core analysis code. These two codes were also used to perform the required operational safety analyses for the FFTF reactor and plant. Although it was intended to also use the SASSYS systems (core and plant) analysis code, the calibration of the SASSYS code for FFTF core and plant analysis was not completed in time to perform pretest analyses. The purpose of this paper is to present the results of the posttest analysis of the 1986 FFTF inherent safety tests using the SASSYS code

    The purpose of this study was to determine if a computer-aided instruction learning module improves students' knowledge of the neuroanatomy/physiology and clinical examination of the dorsal column-medial lemniscal (DCML) system. Sixty-one physical therapy students enrolled in a clinical neurology course in entry-level PT educational programs at two universities participated in the study. Students from University-1 (U1;) had not had a previous neuroanatomy course, while students from University-2 (U2;) had taken a neuroanatomy course in the previous semester. Before and after working with the learning module, students took a paper-and-pencil test on the neuroanatomy/physiology and clinical examination of the DCML system. Kruskal-Wallis one-way ANOVA and Mann-Whitney tests were used to determine if differences existed between neuroanatomy/physiology examination scores and clinical examination scores before and after taking the learning module, and between student groups based on university attended. For students from U1, neuroanatomy/physiology post-test scores improved significantly over pre-test scores (p Neuroanatomy/physiology pre-test scores from U2 were significantly better than those from U1 (p < 0.001); there was no significant difference in post-test scores (p = 0.062). Clinical examination pre-test and post-test scores from U2 were significantly better than those from U1 (p < 0.001). Clinical examination post-test scores improved significantly from the pre-test scores for both U1 (p < 0.001) and U2 (p < 0.001).

Physicians’ knowledge and confidence on the topic is often low and not suitable for manage this challenge. Tailored educational programs are required to reach a more and more appropriate use of genetic technologies.MethodsA distance learning course has been created by experts from different Italian medical associations with the support of the Italian Ministry of Health. The course was directed to professional figures involved in prescription and interpretation of genetic tests. A pretest-post-test study design was used to assess knowledge improvement. We analyzed the proportion of correct answers for each question pre and post-test, as well as the mean score difference stratified by gender, age, professional status and medical specialty.ResultsWe reported an improvement in the proportion of correct answers for 12 over 15 questions of the test. The overall mean score to the questions significantly increased in the post-test, from 9.44 to 12.49 (p-value < 0.0001. In the stratified analysis we reported an improvement in the knowledge of all the groups except for geneticists; the pre-course mean score of this group was already very high and did not improve significantly.ConclusionDistance learning is effective in improving the level of genetic knowledge. In the future, it will be useful to analyze which specialists have more advantage from genetic education, in order to plan more tailored education for medical professionals.

    Diabetes education and self-care remains the cornerstone of diabetes management. There are many structured diabetes modules available in the United Kingdom, Europe and United States of America. Contrastingly, few structured and validated diabetes modules are available in Malaysia. This pilot study aims to develop and validate diabetes education material suitable and tailored for a multicultural society like Malaysia. The theoretical framework of this module was founded from the Health Belief Model (HBM). The participants were assessed using 6-item pre- and post-test questionnaires that measured some of the known HBM constructs namely cues to action, perceived severity and perceived benefit. Data was analysed using PASW Statistics 18.0. The pre- and post-test questionnaires were administered to 88 participants (31 males). In general, there was a significant increase in the total score in post-test (97.34 ± 6.13%) compared to pre-test (92.80 ± 12.83%) (p 85%) at post-test (84.1%) compared to pre-test (70.5%) (p < 0.05). There was an improvement in post-test score in 4 of 6 items tested. The remaining 2 items which measured the perceived severity and cues to action had poorer post-test score. The preliminary results from this pilot study suggest contextualised content material embedded within MY DEMO maybe suitable for integration with the existing diabetes education programmes. This was the first known validated diabetes education programme available in the Malay language.

    When confronted with various findings on thoracic radiographs, fourth-year veterinary students often have difficulty generating appropriate lists of differential diagnoses. The purpose of this one-group, pretest, posttest experimental study was to determine if a game could be used as an adjunct teaching method to improve students' understanding of connections between imaging findings and differential diagnoses. A novel board game focusing on differential diagnoses in thoracic radiography was developed. One hundred fourth-year veterinary students took a brief pretest, played the board game, and took a brief posttest as a part of their respective clinical radiology rotations. Pretest results were compared to posttest results using a paired t-test to determine if playing the game impacted student understanding. Students' mean scores on the posttest were significantly higher than mean pretest scores (P game resulted in improved short-term understanding of thoracic differential diagnoses by fourth-year students, and use of the board game on a clinical rotation seems to be a beneficial part of the learning process. © 2016 American College of Veterinary Radiology.

    As part of the PSI/HSK STARS project, pre-test calculations have been performed for a KKL turbine trip test at 109% power using the RETRAN-3D code. In this paper, we first present the results of these calculations, together with a description of the test and a comparison of the results with the measured plant data, and then discuss in more detail the differences between the pre-test results and the plant measurements, including the differences in the initial and boundary conditions, and how these differences influenced the calculated results. Finally, we comment on a series of post-test and sensitivity analyses, which were performed to resolve some of the discrepancies. The results of the pre-test (blind) calculations show good overall agreement with the experimental data, particularly for the maximum in the steam-line mass flow rate following the opening of the turbine bypass valves. This is of critical importance, since the steam-line flow has the least margin to the reactor scram limit. The agreement is especially good since the control rod banks used for the selected rod insertion were changed from those given in the test specification. Following a review of the comparison of the pre-test calculations with the measured data, several deficiencies in the RETRAN-3D model for KKL were identified and corrected as part of the post-test analysis. This allowed for both an improvement in the calculated results, and a deeper understanding of the behaviour of the turbine trip transient. (author)

    Full Text Available The “gender gap” on various physics conceptual evaluations has been extensively studied. Men’s average pretest scores on the Force Concept Inventory and Force and Motion Conceptual Evaluation are 13% higher than women’s, and post-test scores are on average 12% higher than women’s. This study analyzed the gender differences within the Conceptual Survey of Electricity and Magnetism (CSEM in which the gender gap has been less well studied and is less consistent. In the current study, data collected from 1407 students (77% men, 23% women in a calculus-based physics course over ten semesters showed that male students outperformed female students on the CSEM pretest (5% and post-test (6%. Separate analyses were conducted for qualitative and quantitative problems on lab quizzes and course exams and showed that male students outperformed female students by 3% on qualitative quiz and exam problems. Male and female students performed equally on the quantitative course exam problems. The gender gaps within CSEM post-test scores, qualitative lab quiz scores, and qualitative exam scores were insignificant for students with a CSEM pretest score of 25% or less but grew as pretest scores increased. Structural equation modeling demonstrated that a latent variable, called Conceptual Physics Performance/Non-Quantitative (CPP/NonQnt, orthogonal to quantitative test performance was useful in explaining the differences observed in qualitative performance; this variable was most strongly related to CSEM post-test scores. The CPP/NonQnt of male students was 0.44 standard deviations higher than female students. The CSEM pretest measured CPP/NonQnt much less accurately for women (R^{2}=4% than for men (R^{2}=17%.

    The "gender gap" on various physics conceptual evaluations has been extensively studied. Men's average pretest scores on the Force Concept Inventory and Force and Motion Conceptual Evaluation are 13% higher than women's, and post-test scores are on average 12% higher than women's. This study analyzed the gender differences within the Conceptual Survey of Electricity and Magnetism (CSEM) in which the gender gap has been less well studied and is less consistent. In the current study, data collected from 1407 students (77% men, 23% women) in a calculus-based physics course over ten semesters showed that male students outperformed female students on the CSEM pretest (5%) and post-test (6%). Separate analyses were conducted for qualitative and quantitative problems on lab quizzes and course exams and showed that male students outperformed female students by 3% on qualitative quiz and exam problems. Male and female students performed equally on the quantitative course exam problems. The gender gaps within CSEM post-test scores, qualitative lab quiz scores, and qualitative exam scores were insignificant for students with a CSEM pretest score of 25% or less but grew as pretest scores increased. Structural equation modeling demonstrated that a latent variable, called Conceptual Physics Performance/Non-Quantitative (CPP/NonQnt), orthogonal to quantitative test performance was useful in explaining the differences observed in qualitative performance; this variable was most strongly related to CSEM post-test scores. The CPP/NonQnt of male students was 0.44 standard deviations higher than female students. The CSEM pretest measured CPP/NonQnt much less accurately for women (R2=4 % ) than for men (R2=17 % ). The failure to detect a gender gap for students scoring 25% or less on the pretest suggests that the CSEM instrument itself is not gender biased.

    During medical education, many students experience psychological distress, including symptoms such as fatigue, stress, and depression. To evaluate the effect of osteopathic manipulative treatment (OMT) on self-perceived fatigue, stress, and depression in first-year osteopathic medical students. This randomized controlled pilot study with repeated measures was conducted at the Lake Erie College of Osteopathic Medicine-Bradenton in Florida during the fall 2012 semester. First-year osteopathic medical students voluntarily enrolled in the study and were randomly assigned to directed OMT (D-OMT), nondirected OMT (ND-OMT), or control groups. The D-OMT and ND-OMT groups received treatment by osteopathic physicians weekly for 4 weeks. The control group received no treatment. All groups completed the Epworth Sleepiness Scale (ESS), the Self-Perceived Stress Scale (SPSS), and the Primary Care Evaluation of Mental Disorders Patient Health Questionnaire 9 (PHQ-9) depression scale before treatment (pretest), after 2 treatments (midtest), and after 4 treatments (posttest). All participants self-reported as white and single, with both sexes equally represented, and had an mean age of 24 years. Analysis of ESS scores revealed a statistically significant decrease in the D-OMT group from pretest and posttest scores and a statistically significant increase in the ND-OMT group from pretest to midtest but not from pretest to posttest scores. No statistically significant differences were noted in the control group scores on this measure. No statistically significant differences were seen in the SPSS or PHQ-9 scores from pretest to midtest or pretest to posttest in any of the 3 groups. The D-OMT regimen used in the current study produced a statistically significant decrease in self-perceived fatigue in first-year osteopathic medical students. Osteopathic manipulative treatment represents a potential modality to reduce self-perceived distress in medical students. Further research is

    Lichon, Kathryn A.

    The purpose of this pre-post quasi-experimental dissertation was to investigate the effects of differentiated writing supports on English Proficient Students' (EPSs) and English Language Learners' (ELLs) science content knowledge and explanatory writing about magnetism and electricity. Eighty-seven fourth-grade students (EPSs = 35; ELLs = 52) were randomly assigned to two groups based on two differentiated writing: guided questions ( n = 43) or targeted writing frames (n = 44). In the guided questions condition, students completed four question sets after a science investigation, and in the targeted writing frames condition, students completed the same four question sets, but with explicit support for vocabulary, transitions, and relational language in the form of if-then statements. Over the course of the four week intervention, students completed a total of nine writing tasks, and were pretested and posttested on six variables: magnetism and electricity content knowledge test, explanatory writing task, total number of words written, total number of sentences written, number of if-then statements, and number of content-based vocabulary words. Results indicate that EPSs and ELLs in both writing conditions improved significantly from pretest to posttest on six content and explanatory writing variables, with statistically significant gain scores occurring for the magnetism and electricity content knowledge test in which the targeted writing frames condition had a larger rate of gain. ANCOVA results indicated that in comparing writing conditions, a statistically significant difference was found for magnetism and electricity content knowledge posttests, when controlling for pretests. No statistically significant effects for language classification on the six variables were found when controlling for pretest scores. Interaction effects between writing condition and language classification were statistically significantly different for the interaction effect found on if

    Jeopardy!, Concentration, quiz bowls, and other gaming formats have been incorporated into health sciences classroom and online education. However, there is limited information about the impact of these strategies on learner engagement and outcomes. To address this gap, we hypothesized that gaming would lead to a significant increase in retained short- and long-term medical knowledge with high learner session satisfaction. Using the Jeopardy! game show model as a primary instructional technique to teach geriatrics, 8 PGY2 General Surgery residents were divided into 2 teams and competed to provide the "question" to each stated "answer" during 5 protected block curriculum units (1-h/U). A surgical faculty facilitator acted as the game host and provided feedback and brief elaboration of quiz answers/questions as necessary. Each quiz session contained two 25-question rounds. Paper-based pretests and posttests contained questions related to all core curriculum unit topics with 5 geriatric gaming questions per test. Residents completed the pretests 3 days before the session and a delayed posttest of geriatric topics on average 9.2 weeks (range, 5-12 weeks) after the instructional session. The cumulative average percent correct was compared between pretests and posttests using the Student t test. The residents completed session evaluation forms using Likert scale ratings after each gaming session and each protected curriculum block to assess educational value. A total of 25 identical geriatric preunit and delayed postunit questions were administered across the instructional sessions. The combined pretest average score across all 8 residents was 51.5% for geriatric topics compared with 59.5% (p = 0.12) for all other unit topics. Delayed posttest geriatric scores demonstrated a statistically significant increase in retained medical knowledge with an average of 82.6% (p = 0.02). The difference between delayed posttest geriatric scores and posttest scores of all other unit

    In an era of evidence based medicine research is an essential part of medical profession whether clinical or academic. A research methodology workshop intends to help participants, those who are newer to research field or those who are already doing empirical research. The present study was conducted to assess the changes in knowledge of the participants of a research methodology workshop through a structured questionnaire. With administrative and ethical approval, a four day research methodology workshop was planned. The participants were subjected to a structured questionnaire (pre-test) containing 20 multiple choice questions (Q1-Q 20) related to the topics to be covered in research methodology workshop before the commencement of the workshop and then subjected to similar posttest questionnaire after the completion of workshop. The mean values of pre and post-test scores were calculated and the results were analyzed and compared. Out of the total 153 delegates, 45(29 %) were males and 108 were (71 %) females. 92 (60%) participants consented to fill the pre-test questionnaire and 68 (44%) filled the post-test questionnaire. The mean Pre-test and post-test scores at 95% Confidence Interval were 07.62 (SD ±3.220) and 09.66 (SD ±2.477) respectively. The differences were found to be significant using Paired Sample T test ( P research methodology workshops. Participatory research methodology workshops are good methods of imparting knowledge, also the long term effects needs to be evaluated.

    Thorough and extensive pretesting is the formative research technique that the Program for the Introduction and Adaptation of Contraceptive Technology (PIACT) and its sister organization, the Program for Appropriate Technology in Health (PATH), rely on to develop well-understood and culturally appropriate print materials. Formative research is defined as evaluation activities that occur during a project to determine if the objectives are being met and, if not, to modify the project's direction to ensure that they are. Before materials are finalized or printed, an interviewer should pretest them with representatives of the target population to determine if the intended message is being conveyed and if it is clear and acceptable to them. Pretesting should be done while the materials are still in an unfinished state so audience-generated alterations can be made easily. Revised materials also should be tested until they communicate the inforamtion as intended. Due to the fact that PIACT/PATH work with countries where large percentages of the population are illiterate, its motivational and instructional materials rely on pictures to convey the message. Often, pictures are augmented by a line or 2 of simple text in the local language. This text also requires careful pretesting. Examples from the field demonstrate the importance of pretesting to assure that print materials are appropriate to the group for whom they are being developed. The examples deal with sympbols, positive messages, the use of common objects, extraneous detail, messages about time, and text. Through pretesting, PIACT/PATH has learned that there can be a large discrepancy between what materials developers intend to convey and what the audience understands. Pretesting is an essential formative technique that builds upon information gathered during the materials development process, ensuring the message designer that the materials will effectively address the needs of the target audience.

    National Tobacco Control Programme was launched in India in year 2007-08. It was realized that community health workers can play an important role of agents for positive change to bring down the tobacco morbidity and mortality in the country. Keeping this in view, a health worker guide was developed by the Government of India, Ministry of Health and Family Welfare (GOI) in collaboration with The Union South-East Asia (The Union) in the year 2010. The guide provides the information needed by the most basic level of health workers to effectively address the problem of tobacco use in the community. A modular training was conducted in two jurisdictions in India (namely, Chandigarh and Hamirpur (Himachal Pradesh)) to assess the usefulness of the guide as training material for community health workers in undertaking tobacco control activities at community and village levels. A total of 271 participants were trained, which included 133 from Chandigarh and 138 from Hamirpur. The pre and post-training assessment of knowledge of health worker was done. There was marked increase in post-test scores as compared to the pretest scores. The health workers scoring more than 60% increased from 40% in the pretest to over 80% in the post-test. Only three workers had a post-test score of less than 30% against 54 workers in the pretest. The understanding on tobacco control had increased significantly after the training in each group. It is strongly recommended that such training should be replicated to all community health workers across all the states in India.

    Less than 20% of the 996 NICUs in the United States routinely practice kangaroo care, due in part to the inadequate knowledge and skills confidence of nurses. Continuing education improves knowledge and skills acquisition, but the effects of a kangaroo care certification course on nurses' knowledge and skills confidence are unknown. A pretest-posttest quasi-experiment was conducted. The Kangaroo Care Knowledge and Skills Confidence Tool was administered to 68 RNs at a 2.5-day course about kangaroo care evidence and skills. Measures of central tendency, dispersion, and paired t tests were conducted on 57 questionnaires. The nurses' characteristics were varied. The mean posttest Knowledge score (M = 88.54, SD = 6.13) was significantly higher than the pretest score (M = 78.7, SD = 8.30), t [54] = -9.1, p = .000), as was the posttest Skills Confidence score (pretest M = 32.06, SD = 3.49; posttest M = 26.80, SD = 5.22), t [53] = -8.459, p = .000). The nurses' knowledge and skills confidence of kangaroo care improved following continuing education, suggesting a need for continuing education in this area. J Contin Educ Nurs. 2016;47(11):518-524.

    ABSTRACT Limited evidence may support the application of electrical stimulation in the subacute and chronic stages of facial palsy, yet some physiotherapists in South Africa have been applying this modality in the acute stage in the absence of published evidence of clinical efficacy. This preliminary study's aim was to determine the safety and potential efficacy of applying electrical stimulation to the facial muscles during the early phase of Bells palsy. A pretest posttest control vs. experimental groups design composed of 16 patients with Bell's palsy of less than 30 days' duration. Adult patients with clinical diagnosis of Bell's palsy were systematically (every second patient) allocated to the control and experimental groups. Each group (n = 8) was pretested and posttested using the House-Brackmann index. Both groups were treated with heat, massage, exercises, and a home program. The experimental group also received electrical stimulation. The House-Brackmann Scale of the control group improved between 17% and 50% with a mean of 30%. The scores of the experimental group ranged between 17% and 75% with a mean of 37%. The difference between the groups was not statistically significant (two-tailed p = 0.36). Electrical stimulation as used in this study during the acute phase of Bell's palsy is safe but may not have added value over spontaneous recovery and multimodal physiotherapy. A larger sample size or longer stimulation time or both should be investigated.

    Full Text Available OBJECTIVE: To investigate if E-learning material improves the basal student knowledge level before attending the presential class of blindness prevention (BP and if helps to fix this information one-month after the class. METHODS: Fourth-year medical students were randomly assigned to have a presential class of BP (Traditional group = TG or to have a presential class of BP plus an additional E-learning material (E-learning group = ELG. This material was e-mailed one week before the presential class. The students were submitted to a multiple-choice test (with three options each with seven questions immediately before the presential class, immediately after the class, and one-month later. The three tests had the same questions; however, the answers options were distributed in different sequences. The primary outcome was immediate pretest score. The secondary outcomes were immediate posttest score and one-month posttest score. RESULTS: Among the 120 fourth-year medical students, a random sample of 34 students was assigned to the TG and 34 students was assigned to the ELG. The two groups showed similar immediate posttest score (TG=6.8 and ELG=6.9; P<.754, but the differences at the immediate pretest score (TG=3.6 and ELG=4.7; P<.001, and at the one-month posttest score, were significant (TG=6.1 and ELG=6.8; P<.001. CONCLUSIONS: The pretest and the one-month posttest results suggested that the E-learning material acts as an effective complementary tool of the presential class of blindness prevention.

    Full Text Available The study was to test the effectiveness of the Web-Based Interactive Blended Learning Model (BLIBW for subjects in the Department of Electrical Engineering, Padang State University. The design that the researcher employed was a quasi-experimental design with one group pretest-posttest, which was conducted on a group of students consisting of 30 people and the test was conducted for two times. The effectiveness of BLIBW Model was tested by comparing the average pretest scores and the average posttest scores both in the first trial and the second trial. The average prestest and posttest scores in the first trial were 14.13 and 33.80. The increase in the average score was significant at alpha 0.05. Then, the average pretest and posttest scores in the second trial were 18.67 and 47.03. The result was also significant at alpha 0.05. The effectiveness of BLIBW Model in the second trial was higher than in the first test. Those result were not entirely satisfactory and it might be caused several weaknesses in both tests such as: the number of sessions were limited, there was only one subject, and the number of students who were subjected too limited. However, the researcher would like to conclude that the BLIBW Model might be implemented as a replacement alternative for the face-to-face instruction.

    This study compared the effects of reading-oriented tasks and writing-oriented tasks on students' reading comprehension of geometry proof (RCGP). The reading-oriented tasks were designed with reading strategies and the idea of problem posing. The writing-oriented tasks were consistent with usual proof instruction for writing a proof and applying it. Twenty-two classes of ninth-grade students ( N = 683), aged 14 to 15 years, and 12 mathematics teachers participated in this quasi-experimental classroom study. While the experimental group was instructed to read and discuss the reading tasks in two 45-minute lessons, the control group was instructed to prove and apply the same propositions. Generalised estimating equation (GEE) method was used to compare the scores of the post-test and the delayed post-test with the pre-test scores as covariates. Results showed that the total scores of the delayed post-test of the experimental group were significantly higher than those of the control group. Furthermore, the scores of the experimental group on all facets of reading comprehension except the application facet were significantly higher than those of the control group for both the post-test and delayed post-test.

    This study was conducted to observe the effect of a structured educational program on drug adherence and self-care management in people with epilepsy in a developing country. A total of 180 consecutive people with epilepsy were enrolled from the epilepsy clinic of a tertiary care hospital in North India. Out of these, 90 were randomized to the epilepsy health education group and received the educational program and 90 were in the control group and received the standard of care but did not receive any structured educational program. The modified Morisky Medication Adherence Scale (MMAS) and Epilepsy Self-Efficacy Scale (ESES) were administered to assess drug adherence and self-care, respectively, on the day of enrollment. The patients enrolled in the epilepsy health education group received 4 sessions of the structured educational program. The MMAS and ESES questionnaires were again administered to both groups after 6months. Continuous and categorical variables were compared between control and epilepsy health education groups using a chi-square test, with p value less than 0.05 considered significant. A comparison between pretest and posttest MMAS scores and ESES scores was done using a paired t-test. In the epilepsy health education group, the pretest mean MMAS score was 6.58 whereas the posttest mean MMAS score was 7.53; the difference was significant (p=0.001). The mean MMAS scores for the control group's pretest and posttest were 6.46 and 6.58, respectively, which were not significantly different (p=0.224). On comparing the ESES scores at the beginning of the study and after 6months, there was no significant change in both groups. The present study proves the efficacy of a structured educational program in improving drug adherence in a cohort of people with epilepsy with low educational background.

    The flexibility of a hospital's nursing-related human resource management policies affects the working willingness and retention of nurses. To explore the effectiveness of a flexible nursing-related human resource management strategy. This quasi-experimental research used a one group pretest-posttest design. Supervisors at participating hospitals attended the "Application of Flexible Nursing Human Resources Management Strategies" workshop, which introduced the related measures and assessed nurses' pretest satisfaction. After these measures were implemented at the participating hospitals, implementation-related problems were investigated and appropriate consultation was provided. The posttest was implemented after the end of the project. Data were collected from nurses at the participating hospitals who had served in their present hospital for more than three months. The participating hospitals were all nationally certified healthcare providers, including 13 medical centers, 17 regional hospitals, and 3 district hospitals. A total of nurses 2,810 nurses took the pretest and 2,437 took the posttest. The research instruments included the "Satisfaction with working conditions and system flexibility" scale and the "Flexible nursing human resource management strategies". The effectiveness of the implemented strategy was assessed using independent samples t-test and variance analysis. The result of implementing the flexible strategies shows that the total mean of pretest satisfaction (Likert 5 scores) was 3.47 (SD = 0.65), and the posttest satisfaction was 3.52 (SD = 0.65), with significant statistical differences in task, numerical, divisional, and leading flexibility. Due to the good implementation effectiveness, the authors strongly suggest that all of the participating hospitals continue to apply this strategic model to move toward a more flexible nursing system and work.

    Objective: To evaluate the effect of simulation-based mastery learning (SBML) on internal medicine residents' lumbar puncture (LP) skills, assess neurology residents' acquired LP skills from traditional clinical education, and compare the results of SBML to traditional clinical education. Methods: This study was a pretest-posttest design with a comparison group. Fifty-eight postgraduate year (PGY) 1 internal medicine residents received an SBML intervention in LP. Residents completed a baseline skill assessment (pretest) using a 21-item LP checklist. After a 3-hour session featuring deliberate practice and feedback, residents completed a posttest and were expected to meet or exceed a minimum passing score (MPS) set by an expert panel. Simulator-trained residents' pretest and posttest scores were compared to assess the impact of the intervention. Thirty-six PGY2, 3, and 4 neurology residents from 3 medical centers completed the same simulated LP assessment without SBML. SBML posttest scores were compared to neurology residents' baseline scores. Results: PGY1 internal medicine residents improved from a mean of 46.3% to 95.7% after SBML (p < 0.001) and all met the MPS at final posttest. The performance of traditionally trained neurology residents was significantly lower than simulator-trained residents (mean 65.4%, p < 0.001) and only 6% met the MPS. Conclusions: Residents who completed SBML showed significant improvement in LP procedural skills. Few neurology residents were competent to perform a simulated LP despite clinical experience with the procedure. PMID:22675080

    Students are relying on technology for learning more than ever, and educators need to adapt to facilitate student learning. High-fidelity patient simulators (HFPS) are usually reserved for the clinical years of medical education and are geared to improve clinical decision skills, teamwork, and patient safety. Finding ways to incorporate HFPS into preclinical medical education represents more of a challenge, and there is limited literature regarding its implementation. The main objective of this study was to implement a HFPS activity into a problem-based curriculum to enhance the learning of basic sciences. More specifically, the focus was to aid in student learning of cardiovascular function curves and help students develop heart failure treatment strategies based on basic cardiovascular physiology concepts. Pretests and posttests, along with student surveys, were used to determine student knowledge and perception of learning in two first-year medical school classes. There was an increase of 21% and 22% in the percentage of students achieving correct answers on a posttest compared with their pretest score. The median number of correct questions increased from pretest scores of 2 and 2.5 to posttest scores of 4 and 5 of a possible total of 6 in each respective year. Student survey data showed agreement that the activity aided in learning. This study suggests that a HFPS activity can be implemented during the preclinical years of medical education to address basic science concepts. Additionally, it suggests that student learning of cardiovascular function curves and heart failure strategies are facilitated.

    Long-term care institutions have become an option for older people who are dependent in daily living. However, insufficient attention has been focused on assessing the life satisfaction of those currently residing in these institutions in Taiwan. Previous research indicates that group reminiscence may improve the life satisfaction of older adults. However, there is currently no consensus regarding the implementation and evaluation of reminiscence interventions. To examine the effect of a structured group reminiscence protocol on the life satisfaction of institutionalized older adults. The study used a quasi-experimental design. A total of 48 older adults were conveniently recruited from two long-term care institutions in southern Taiwan. The experimental group (n = 23) received 8 weeks of structured-group reminiscence for 40 minutes weekly, while the control group (n = 25) received routine care from the institution. Both groups were evaluated using a life-satisfaction questionnaire before and after the intervention and again four weeks later. Life satisfaction scores were statistically similar on the pre-test and significantly different on both post-test questionnaires for the two groups. The scores for the experimental and control groups were pre-test: 24.22 vs 23.36 (p = .063); post-test I: 27.22 vs 23.32 (p < .001); and post-test II: 26.43 vs 23.00 (p < .001). The mean post-test scores for the experimental group were significantly higher than the pre-test score (p < .001). The generalized estimating equation test showed that the overall score of life satisfaction for the experimental group increased by 0.85-points (p = .042) more than the control group, which is a significant difference. The results support that the 8-week structured group reminiscence protocol effectively enhances life satisfaction in older adults. The results of this study may be referenced in the continuing education of nurses working in long-term care institutions in the context of helping

    The purpose of this study was to determine if the use of active-learning activities to teach weak force and strong force to students enrolled in various courses at The University of Southern Mississippi, Hattiesburg campus and Gulf Park campus at different class times would increase their knowledge. There were eighty-six students that took part in this study. The study was conducted in the lab classes of an introductory astronomy survey course (AST 111), an introductory algebra-based physics course (PHY 112), and an introductory calculus-based physics course (PHY 202) during fall semester, 2014. Each class was randomly assigned as active-learning or direct instruction. A pretest followed by lecture was administered to all groups. The active-learning group performed four activities whereas the direct group watched a video irrelevant to the lesson. At the end of the lesson, the same post-test was given to all groups. Various statistical methods were used to analyze the differences in mean pretest and posttest scores. Overall, results show that the mean posttest scores were higher than the mean pretest scores. Findings support the use of active-learning activities work to the small number of students or the equal number of students in a group. The mean posttest scores of the direct instruction classes were higher than those of the active-learning groups.

    Full Text Available This research aimed to find out whether the skimming and scanning techniques (SST can improve EFL students’ English reading comprehension in recount texts, especially on identifying the main ideas and detail information, in a senior high school in Meulaboh, Aceh, Indonesia. A number of 32 eleventh grade students participated in this study, and the one group pre-test and post-test design were used. Data collection was from a pre-test and a post-test. In analyzing the data, statistics was used. The results showed that the mean score of the pre-test was 45 and the post-test was 65, with 20 points of improvement. Furthermore, the result of t-test was 4.7, while the critical value of 0.05 significant level was 2.4, with the degree of freedom at 23. Since t-test>t-score, thus SST improved the students’ reading comprehension in this study. Nevertheless, the paper further discusses some setbacks while implementing SST in the classroom.

    It is expected that nursing education improves abilities of students in solving problems, decision making and critical thinking in different circumstances. This study was performed to analyse the effects of care plans prepared using concept maps on the critical thinking dispositions of students. An experimental group and a control group were made up of a total of 80 freshman and sophomore students from the nursing department of a health school. The study used a pre-test post-test control group design. The critical thinking dispositions of the groups were measured using the California Critical Thinking Disposition Inventory. In addition, the care plans prepared by the experimental group students were evaluated using the criteria for evaluating care plans with concept maps. T-test was used in analysing the data. The results showed that there were no statistically significant differences in the total and sub-scale pre-test scores between the experimental group and control group students. There were also significant differences in the total and sub-scale post-test scores between the experimental group and control group students. There were significant differences between concept map care plan evaluation criteria mean scores of the experimental students. In the light of these findings, it could be argued that the concept mapping strategy improves critical thinking skills of students. © 2012 Blackwell Publishing Asia Pty Ltd.

    The objective of this study was to assess whether a 1-hour didactic session on the DSM-5 Cultural Formulation Interview (CFI) improves the cultural competence of general psychiatry residents. The main hypothesis was that teaching adult psychiatry residents a 1-hour session on the CFI would improve cultural competence. The exploratory hypothesis was that trainees with more experience in cultural diversity would have a greater increase in cultural competency scores. Psychiatry residents at a metropolitan, county hospital completed demographics and preintervention questionnaires, were exposed to a 1-hour session on the CFI, and were given a postintervention questionnaire. The questionnaire was an adapted version of the validated Cultural Competence Assessment Tool . Paired samples t tests compared pre- to posttest change. Hierarchical linear regression assessed whether pretraining characteristics predicted posttest scores. The mean change of total pre- and posttest scores was significant ( p = .002), as was the mean change in subscales Nonverbal Communications ( p < .001) and Cultural Knowledge ( p = .002). Demographic characteristics did not predict higher posttest scores (when covarying for pretest scores). Psychiatry residents' cultural competence scores improved irrespective of previous experience in cultural diversity. More research is needed to further explore the implications of the improved scores in clinical practice.

    Although statistical knowledge and skills are necessary for promoting evidence-based practice, health sciences students have expressed anxiety about statistics courses, which may hinder their learning of statistical concepts. To evaluate the effects of a biostatistics course on nursing students' attitudes toward statistics and to explore the association between these attitudes and their performance in the course examination. One-group quasi-experimental pre-test/post-test design. Undergraduate nursing students of the fifth or higher semester of studies, who attended a biostatistics course. Participants were asked to complete the pre-test and post-test forms of The Survey of Attitudes Toward Statistics (SATS)-36 scale at the beginning and end of the course respectively. Pre-test and post-test scale scores were compared, while correlations between post-test scores and participants' examination performance were estimated. Among 156 participants, post-test scores of the overall SATS-36 scale and of the Affect, Cognitive Competence, Interest and Effort components were significantly higher than pre-test ones, indicating that the course was followed by more positive attitudes toward statistics. Among 104 students who participated in the examination, higher post-test scores of the overall SATS-36 scale and of the Affect, Difficulty, Interest and Effort components were significantly but weakly correlated with higher examination performance. Students' attitudes toward statistics can be improved through appropriate biostatistics courses, while positive attitudes contribute to higher course achievements and possibly to improved statistical skills in later professional life.

    Early adolescent girls' rates of drug use have matched, and in some instances, surpassed boys' rates. Though girls and boys share risk factors for drug use, girls also have gender-specific risks. Tailored interventions to prevent girls' drug use are warranted. This study developed and tested a web-based, drug abuse prevention program for adolescent girls. The nationwide sample of 13- and 14-year-old girls (N = 788) was recruited via Facebook ads. Enrolled girls were randomly assigned to the intervention or control condition. All girls completed pretest measures online. Following pretest, intervention girls interacted with the 9-session, gender-specific prevention program online. The program aimed to reduce girls' drug use and associated risk factors by improving their cognitive and behavioral skills around such areas as coping with stress, managing mood, maintaining a healthy body image, and refusing drug use offers. Girls in both conditions again completed measures at posttest and 1-year follow-up. At posttest, and compared to girls in the control condition, girls who received the intervention smoked fewer cigarettes and reported higher self-esteem, goal setting, media literacy, and self-efficacy. At 1-year follow-up, and compared to girls in the control condition, girls who received the intervention reported engaging in less binge drinking and cigarette smoking; girls assigned to the intervention condition also had higher alcohol, cigarette, and marijuana refusal skills, coping skills, and media literacy and lower rates of peer drug use. This study's findings support the use of tailored, online drug abuse prevention programming for early adolescent girls.

    Introduction Pre-menopause in women presents with diverse symptoms, encompassing the tri-dimensional spheres of physical, social and psychological domains, which requires development of appropriate coping strategies to overcome these problems. Aim To assess level of knowledge about tri-dimensional problems in pre-menopausal women and evaluate effectiveness of self instruction module on coping strategies of these problems by pre-test and post-test analysis. Materials and Methods In a cross-sectional, community based study, in pre-menopausal women aged 40-49years baseline knowledge of tridimensional problems was assessed in 300 pre-menopausal women, selected by convenient sampling after satisfying selection criteria, by a pre-formed questionnaire. This was followed by administration of a pre-tested, Self-Instructional Module (SIM). The SIM dealt with imparting knowledge about coping strategies regarding pre-menopausal problems and the participants were required to read and retain the SIM. Post-test was conducted using same questionnaire after seven days. Statistical Analysis Chi-square test/ Paired t-test was used for comparing ratios. A ‘p-value’ <0.05 was considered statistically significant. Results Baseline knowledge of tridimensional problems was adequate in 10%, moderate in 73% and inadequate in 17% women with a pre-test mean knowledge score of 8.66±2.45. The post-test mean knowledge score was higher (19.11±3.38) compared to the pre-test score. The post-test mean knowledge difference from pre-test was -10.45 with a highly significant paired t-value of -47.45 indicating that the self-instructional module was effective in increasing the knowledge score of pre- menopausal women under study. Conclusion Administration of self instructional module was shown to significantly increase the knowledge scores in all areas of pre-menopausal tri-dimensional problems. Such self-instructional module can be used as an effective educational tool in increasing the knowledge

    Professional values are standards for action and provide a framework for evaluating behavior. This study examined changes in the professional values of nursing students between their entrance to and graduation from an undergraduate nursing program. A pre- and post-test design was employed. A convenience sample of 94 students from a university in Taiwan was surveyed. Data were collected from students during the sophomore and senior years. Total scores obtained for the revised Nurses Professional Values Scale during the senior year of the nursing program were significantly higher than upon program entry. The 'caring' subscale was scored highest at both program entry and graduation, but the pre- and post-test scores were not significantly different from each other. The students scored significantly higher on the 'professionalism' and 'activism' subscales at post-test than they did at pre-test. Professional values changed in a positive direction between the beginning of the student nurses' educational experience and their graduation. The results supported the premise that education had a positive effect on these students' professional values but causality could not be assumed.

    The present study compares the highly interactive cloud-classroom (HIC) system with traditional methods of teaching materials science that utilize crystal structure picture or real crystal structure model, in order to examine its learning effectiveness across three dimensions: knowledge, comprehension and application. The aim of this study was to evaluate the (HIC) system, which incorporates augmented reality, virtual reality and cloud-classroom to teach basic materials science courses. The study followed a pretest-posttest quasi-experimental research design. A total of 92 students (aged 19-20 years), in a second-year undergraduate program, participated in this 18-week-long experiment. The students were divided into an experimental group and a control group. The experimental group (36 males and 10 females) was instructed utilizing the HIC system, while the control group (34 males and 12 females) was led through traditional teaching methods. Pretest, posttest, and delayed posttest scores were evaluated by multivariate analysis of covariance. The results indicated that participants in the experimental group who used the HIC system outperformed the control group, in the both posttest and delayed posttest, across three learning dimensions. Based on these results, the HIC system is recommended to be incorporated in formal materials science learning settings.

    South Asians, the second fastest growing racial/ethnic minority in the United States, have high rates of coronary heart disease. Few coronary heart disease prevention efforts target this population. The authors developed and tested a culture-specific, multimedia coronary heart disease prevention education program in English and Hindi for South Asians. Participants were recruited from community organizations in Chicago, Illinois, between June and October of 2011. Bilingual interviewers used questionnaires to assess participants' knowledge and perceptions before and after the patient education program. The change from pretest score to posttest score was calculated using a paired t test. Linear regression was used to determine the association between posttest scores and education and language. Participants' (N = 112) average age was 41 years, 67% had more than a high school education, and 50% spoke Hindi. Participants' mean pretest score was 15 (SD = 4). After the patient education program, posttest scores increased significantly among all participants (posttest score = 24, SD = 4), including those with limited English proficiency. Lower education was associated with a lower posttest score (β = -2.2, 95% CI [-0.68, -3.83]) in adjusted regression. A culture-specific, multimedia patient education program significantly improved knowledge and perceptions about coronary heart disease prevention among South Asian immigrants. Culturally salient multimedia education may be an effective and engaging way to deliver health information to diverse patient populations.

    This study aimed to evaluate whether using the interRAI Palliative Care instrument (the interRAI PC) in nursing homes is associated with reduced needs and symptoms in residents nearing the end of their lives. A quasi-experimental pretest-posttest study using the Palliative care Outcome Scale (POS) was conducted to compare the needs and symptoms of residents nearing the end of their lives in the control and intervention nursing homes. Care professionals at the intervention nursing homes filled out the interRAI PC over the course of a year for all residents aged 65 years and older who were nearing the end of their lives. This intervention was not implemented in the control nursing homes. At baseline, POS scores in the intervention nursing homes were lower (more favorable) than in the control nursing homes on the items "pain", "other symptoms", "family anxiety", and the total POS score. Posttest POS scores for "wasted time" were higher (less favorable) than pretest scores in the intervention nursing homes. In the intervention nursing homes where care professionals did not have prior experience with the interRAI Long-Term Care Facilities (LTCF) assessment instrument (n = 8/15), total POS scores were lower (more favorable) at posttest. One year after introducing the interRAI PC, no reduction in residents' needs and symptoms were detected in the intervention nursing homes. However, reductions in needs and symptoms were found in the subgroup of intervention nursing homes without prior experience with the interRAI LTCF instrument. This may suggest that the use of an interRAI instrument other than the interRAI PC specifically can improve care. Future research should aim at replicating this research with a long-term design in order to evaluate the effect of integrating the use of the interRAI PC in the day-to-day practices at nursing homes.

    Full Text Available Speaking is an important skill in language learning and EFL learners sometimes face difficulties when they want to speak. This study attempted to measure the effect of Kagan’s cooperative structures on speaking skill of Iranian EFL learners. The participants were selected from EFL learners studying at Ideal Language Institute. The Cambridge English Language Assessment was administered in order to select homogenous participants. Forty eight adult female EFL learners were selected as intermediate learners based on their results of the language proficiency test. They were divided into two groups, 24 as the control group and 24 as the experimental group. A pre-test was administered to both groups at the beginning of the experiment then, the students participated in 90 minute classes two times a week for eight sessions. At the end of the experiment, a post-test was assigned to both groups to determine whether the Kagan’s cooperative structures had positively affected the students’ speaking skills. The normality of data was tested through Skewness, Kurtosis, and K-S. To make sure the participants were homogenous, the parametric statistical technique of independent -samples t-test was calculated between the pre-tests of both groups and they were homogenous. Independent-samples t-test between the posttests of the experimental group and the control group was calculated and it showed that the participants of the experimental group outperformed the subjects of the control group. Moreover, paired-samples ttest between the pre-test and post-test of the experimental group was calculated and it was shown that the experimental participants progressed from the pre-test to the post-test. The study revealed that: (1 Kagan’s cooperative structures had a positive effect on the students’ speaking skills, (2 the experimental group obtained higher scores in the post-test than in the pre-test, making the difference between the pre-test and post-test scores

    This study was conducted to determine whether the addition of high-fidelity patient simulation to new nurse orientation enhanced critical thinking and clinical decision-making skills. A pretest-posttest design was used to assess critical thinking and clinical decision-making skills in two groups of graduate nurses. Compared with the control group, the high-fidelity patient simulation group did not show significant improvement in mean critical thinking or clinical decision-making scores. When mean scores were analyzed, both groups showed an increase in critical thinking scores from pretest to posttest, with the high-fidelity patient simulation group showing greater gains in overall scores. However, neither group showed a statistically significant increase in mean test scores. The effect of high-fidelity patient simulation on critical thinking and clinical decision-making skills remains unclear. Copyright 2012, SLACK Incorporated.

    Objectives To compare how patients with chest pain would be investigated, based on the two guidelines available for UK cardiologists, on the management of patients with stable chest pain. The UK National Institute of Clinical Excellence (NICE) guideline which was published in 2010 and the European society of cardiology (ESC) guideline published in 2013. Both guidelines utilise pre-test probability risk scores, to guide the choice of investigation. Design We undertook a large retrospective study to investigate the outcomes of stress echocardiography. Setting A large tertiary centre in the UK in a contemporary clinical practice. Participants Two thirds of the patients in the cohort were referred from our rapid access chest pain clinics. Results We found that the NICE risk score overestimates risk by 20% compared to the ESC Risk score. We also found that based on the NICE guidelines, 44% of the patients presenting with chest pain, in this cohort, would have been investigated invasively, with diagnostic coronary angiography. Using the ESC guidelines, only 0.3% of the patients would be investigated invasively. Conclusion The large discrepancy between the two guidelines can be easily reduced if NICE adopted the ESC risk score. PMID:26673458

    Unintentional injury is the leading cause of death for those aged 0 years to 19 years. St. Louis Children's Hospital created Safety Land, a comprehensive injury prevention intervention which is provided during summer months. This program uses a life-size board game to teach safety education to children in ages 5 years to 11 years. The purpose of this study was to evaluate the effect of Safety Land on safety knowledge in children that participated in the intervention. St. Louis Children's Hospital identified ZIP codes with the highest use of the emergency room for injury. Daycares and summer camps within these ZIP codes were targeted for the Safety Land intervention. A multiple choice pretest and posttest survey was designed to measure knowledge change within program participants. Students were selected for testing based on site availably. Within these sites, a convenience sample of children was selected for pretesting and posttesting. Safety Land staff conducted the pretest a week before the intervention, and the posttest was administered the week after the intervention. A total knowledge score was calculated to determine overall knowledge change. Descriptive statistics and independent-samples t tests were conducted to determine statistical significance of change in knowledge (p changes in these youth.

    Radiation therapy treatment planning has advanced over the past 2 decades, with increased emphasis on 3-dimensional imaging for target and organ-at-risk (OAR) delineation. Recent studies suggest a need for improved resident instruction in this area. We developed and evaluated an intensive national educational course ("boot camp") designed to provide dedicated instruction in site-specific anatomy, radiology, and contouring using a multidisciplinary (MDT) approach. The anatomy and radiology contouring (ARC) boot camp was modeled after prior single-institution pilot studies and a needs-assessment survey. The boot camp incorporated joint lectures from radiation oncologists, anatomists, radiologists, and surgeons, with hands-on contouring instruction and small group interactive seminars using cadaveric prosections and correlative axial radiographs. Outcomes were evaluated using pretesting and posttesting, including anatomy/radiology multiple-choice questions (MCQ), timed contouring sessions (evaluated relative to a gold standard using Dice similarity metrics), and qualitative questions on satisfaction and perceived effectiveness. Analyses of pretest versus posttest scores were performed using nonparametric paired testing. Twenty-nine radiation oncology residents from 10 Canadian universities participated. As part of their current training, 29%, 75%, and 21% receive anatomy, radiology, and contouring instruction, respectively. On posttest scores, the MCQ knowledge scores improved significantly (pretest mean 60% vs posttest mean 80%, Pradiology in addition to enhancing their confidence and accuracy in contouring.

    interviews pre and post revealed students' mental model or thought process towards chemical equilibrium. Simulations used in the study were developed using the SCRATCH software platform. In order to test the effect of visualization tool on students' conceptual understanding of chemical equilibrium, an ANCOVA analysis was conducted. Results from a one-factor ANCOVA showed posttest scores were significantly higher for the experimental group (Mpostadj. = 7.27 SDpost = 1.387) relative to the control group (Mpostadj. = 2.67, SDpost = 1.371) after adjusting for pretest scores, F (1,24) = 71.82, MSE = 1.497, p = 0.03, eta 2p = 0.75, d = 3.33. Cohen's d was converted to an attenuated effect size d* using the procedure outlined in Thompson (2006). The adjusted (for pretest scores) group mean difference estimate without measure error correction for the posttest scores and the pretest scores was 4.2 with a Cohen's d = 3.04. An alternate approach reported in Cho and Preacher (2015) was used to determine effect size. The adjusted (for pretest scores) group mean difference estimate with measurement error correction only for the posttest scores (but not with measurement error correction for the pretest scores) was 4.99 with a Cohen's d = 3.61. Finally, the adjusted (for pretest scores) group mean difference estimate with measurement error correction for both pretest and posttest scores was 4.23 with a Cohen's d = 3.07. From a quantitative perspective, these effect size indicate a strong relationship between the experimental intervention provided and students' conceptual understanding of chemical equilibrium concepts. That is, those students who received the experimental intervention had exceptionally higher. KEYWORDS: Chemical Equilibrium, Visualization, Alternate Conceptions, Ontological Shift. Simulations.

    Blended learning as a method of learning that includes face to face learning, pure E-learning and didactic learning. This study aims to investigate the efficacy of medical education by this approach. This interventional study was performed in 130 students at different clinical levels participating in class sessions on "congenital adrenal hyperplasia and ambiguous genitalia". Sampling was done gradually during 6 months and all of them filled a pretest questionnaire and received an educational compact disk. One week later, a presence class session was held in a question and answer and problem solving method. Two to four weeks later, they filled a posttest questionnaire. There was a significant correlation between pretest and posttest scores and the posttest scores were significantly more than the pretest ones. Sub-specialized residents had the most and the students had the least attitude towards blended learning approach. There was a significant correlation between the research samples' accessibility to computer and their attitude and satisfaction to blended learning approach. Findings generally showed that the blended learning was an effective approach in making a profound learning of academic subjects.

    This preliminary study developed a digital graphic novella targeting hearing protection beliefs of Spanish-speaking agricultural workers. Researchers used pretest-posttest interview surveys to establish if the novella had an immediate influence on the participants' beliefs about noise-induced hearing loss and usage of hearing protection devices. Researchers developed a digital graphic novella directed to increase knowledge about noise-induced hearing loss and increase the proper use of hearing protection devices. The novella was tailored to meet the specific linguistic and literacy needs of Spanish-speaking agricultural workers. Thirty-one Spanish-speaking farmworkers of Mexican nationality participated. This study included an interview survey with specific questions on noise-induced hearing loss, myths, and hearing protection device usage. A pretest-posttest design was applied to measure the graphic novella's immediate influence on workers. The posttest scores on Hearing Protection Beliefs statements were significantly better than pretest scores, with a large effect size observed. Digital media may be an effective way to overcome language and literacy barriers with Spanish-speaking workers when providing health education and prevention efforts.

    This article is a report of a quasi-experimental study of the effects of blended modules on nursing students' learning of ethics course content. There is yet to be an empirically supported mix of strategies on which a working blended learning model can be built for nursing education. This was a two-group pretest and post-test quasi-experimental study in 2008 involving a total of 233 students. Two of the five clusters were designated the experimental group to experience a blended learning model, and the rest were designated the control group to be given classroom lectures only. The Case Analysis Attitude Scale, Case Analysis Self-Evaluation Scale, Blended Learning Satisfaction Scale, and Metacognition Scale were used in pretests and post-tests for the students to rate their own performance. In this study, the experimental group did not register significantly higher mean scores on the Case Analysis Attitude Scale at post-test and higher mean ranks on the Case Analysis Self-Evaluation Scale, the Blended Learning Satisfaction Scale, and the Metacognition Scale at post-test than the control group. Moreover, the experimental group registered significant progress in the mean ranks on the Case Analysis Self-Evaluation Scale and the Metacognition Scale from pretest to post-test. No between-subjects effects of four scales at post-test were found. Newly developed course modules, be it blended learning or a combination of traditional and innovative components, should be tested repeatedly for effectiveness and popularity for the purpose of facilitating the ultimate creation of a most effective course module for nursing education. © 2011 Blackwell Publishing Ltd.

    In-service education affects the quality of cancer care directly. Using classroom teaching to deliver in-service education is often ineffective due to participants' large workload and shift requirements. This study evaluated the learning effectiveness of different teaching methods in the dimensions of knowledge, attitude, and learning satisfaction. This study used a quasi-experimental study design. Participants were cancer ward nurses working at one medical center in northern Taiwan. Participants were divided into an experimental group and control group. The experimental group took an e-learning course and the control group took a standard classroom course using the same basic course material. Researchers evaluated the learning efficacy of each group using a questionnaire based on the quality of cancer nursing care learning effectiveness scale. All participants answered the questionnaire once before and once after completing the course. (1) Post-test "knowledge" scores for both groups were significantly higher than pre-test scores for both groups. Post-test "attitude" scores were significantly higher for the control group, while the experimental group reported no significant change. (2) after a covariance analysis of the pre-test scores for both groups, the post-test score for the experimental group was significantly lower than the control group in the knowledge dimension. Post-test scores did not differ significantly from pre-test scores for either group in the attitude dimension. (3) Post-test satisfaction scores between the two groups did not differ significantly with regard to teaching methods. The e-learning method, however, was demonstrated as more flexible than the classroom teaching method. Study results demonstrate the importance of employing a variety of teaching methods to instruct clinical nursing staff. We suggest that both classroom teaching and e-learning instruction methods be used to enhance the quality of cancer nursing care education programs. We

    Full Text Available The role of student interactions in learning situations is a foundation of sociocultural learning theory, and social network analysis can be used to quantify student relations. We discuss how self-reported student interactions can be viewed as processes of meaning making and use this to understand how quantitative measures that describe the position in a network, called centrality measures, can be understood in terms of interactions that happen in the context of a university physics course. We apply this discussion to an empirical data set of self-reported student interactions. In a weekly administered survey, first year university students enrolled in an introductory physics course at a Danish university indicated with whom they remembered having communicated within different interaction categories. For three categories pertaining to (1 communication about how to solve physics problems in the course (called the PS category, (2 communications about the nature of physics concepts (called the CD category, and (3 social interactions that are not strictly related to the content of the physics classes (called the ICS category in the introductory mechanics course, we use the survey data to create networks of student interaction. For each of these networks, we calculate centrality measures for each student and correlate these measures with grades from the introductory course, grades from two subsequent courses, and the pretest Force Concept Inventory (FCI scores. We find highly significant correlations (p<0.001 between network centrality measures and grades in all networks. We find the highest correlations between network centrality measures and future grades. In the network composed of interactions regarding problem solving (the PS network, the centrality measures hide and PageRank show the highest correlations (r=-0.32 and r=0.33, respectively with future grades. In the CD network, the network measure target entropy shows the highest correlation

    Full Text Available The effect of using tests in test preparation courses has been subject to debate. While some scholars such as Yang and Badger (2015 believe it is a cause of positive washback effect, others argue that this issue is tentative and context-bound (Green, 2007. Therefore, this study investigated the effect of using Mock tests in International English Language Testing System (IELTS preparation courses on students’ overall IELTS scores. Fifty one IELTS students were selected non-randomly through the quota sampling approach out of 76 students at Mahan Language Institute in Birjand, Iran.  These participants were distributed into Group 1 (n=25 and Group 2 (n=26. A complete IELTS test was administered to ensure that the Groups were homogeneous and to serve as pretest. After 10 sessions of intervention, a different IELTS test was administered as posttest. The results of between subject analysis through independent samples t-test revealed that using Mock tests in the IELTS preparation courses can positively affect the participants scores on IELTS exam. Pedagogical implications are discussed.

    Brylske, Alexander Frederick

    While a number of instructional models focus on the use of analogies, research into their effectiveness in enhancing comprehension and retention of scientific concepts, particularly involving adult learners, has been limited. The purpose of this study was to determine the efficacy of using the common teaching strategy for comparing the function of a coral reef to that of a city by using an analogy-based instructional model termed FAR. The training program entitled "Marine Resource Management for Dive Professionals" (MRMDP) was developed for this study. It was targeted to professionals in the recreational scuba industry to improve their understanding of coal reef ecology, as well as orient them to pertinent marine resource management issues, and promote environmentally-responsible attitudes and diving practices among their clients. A quasi-experimental pre-post-delayed posttest control group design was used to explore five research questions and corresponding hypotheses. A 55-item researcher-developed test of coral reef ecology was administered pre and post instruction. The delayed posttest was self-administered by the subjects three weeks after course completion. Data on seven experiential variables hypothesized as research factors were collected. Ten MRMPD courses were taught in seven nations, involving 194 subjects (85 subjects in four control courses, 109 in six treatment course). The results were analyzed using multiple regression/correlation (MRC) techniques to determine: (1) any significant relationship between pretest performance and experiential variables, (2) treatment versus control group posttest performance, and (3) treatment versus control group delayed posttest performance. Within the treatment group, learning gains and retention were determined by t-test analysis. Results indicated: (1) all research factors except one were significant predictors of pretest scores in the presence of the covariate; (2) no significant difference was found between

    Full Text Available Research on figuring out the ways to teach creative thinking skills via learning processes has been carried out. One of the methods applied to be efficient to teach creative thinking skills is laboratory work. Laboratory work is an important process in learning physics since students tend to find it hard to understand physical concepts if they are only taught verbally. Students will understand better when they are given real life examples and are allowed to learn the concepts through the laboratory work, whenever possible. The research was conducted at SMAN 1 Bringin by employing the quasi-experiment pre-test - post-test control group design. Creative thinking skills were measured based on four indicators: flexibility, fluency, originality, and detail. Results show that laboratory work was suitable to improve students’ fluent thinking ability with 77% students showing improvement, and it was also a fit to improve students’ original thinking with 84% students showing improvement. The experiment class revealed a gain of 0.51, taken from an average pre-test score of 45.64 compared to the average post-test score of 73.5, which is an increase of 27.86. Meanwhile, the control class resulted in a gain of 0.40, taken from an average pre-test score of 39.11 compared to the average post-test score of 83.44, which is an increase of 24.33.

    Failure to recognize and appropriately manage dengue early in the clinical course may result in late initiation of supportive treatment for severe disease. In Florida, travel-related and autochthonous dengue occur and are likely under-recognized. The objective of this study was to evaluate physician knowledge of dengue and its management before and after an educational intervention in Florida. From 2012-13 we conducted 14 grand-rounds style lectures on dengue clinical management attended by 413 physicians, and analyzed data from the pre- and post-tests. Of those attending, 231 and 220 completed the pre-and post-tests, respectively. Overall, the mean pre-test score for knowledge-based questions was 74.3 and average post-test score was 94.2%, indicating a mean increase of 19.9% (P dengue recognition and management also increased. Non-US trained physicians and those who had treated more than ten dengue cases performed significantly better in the pre-test. Post-test scores did not differ by subgroup. The train-the-trainer approach with grand-rounds style presentations appear to be an effective intervention to improve knowledge of dengue among physicians.

    To compare lecture-based learning (LBL) and discussion-based learning (DBL) by assessing immediate and long-term knowledge retention and application of practical knowledge in third- and fourth-year medical students. A prospective, randomized control trial was designed to study the effects of DBL. Medical students were randomly assigned to intervention (DBL) or control (LBL) groups. Both the groups were instructed regarding the management of gastroschisis. The control group received a PowerPoint presentation, whereas the intervention group was guided only by an objectives list and a gastroschisis model. Students were evaluated using a multiple-choice pretest (Pre-Test MC) immediately before the teaching session, a posttest (Post-Test MC) following the session, and a follow-up test (Follow-Up MC) at 3 months. A practical examination (PE), which tested simple skills and management decisions, was administered at the end of the clerkship (Initial PE) and at 3 months after clerkship (Follow-Up PE). Students were also given a self-evaluation immediately following the Post-Test MC to gauge satisfaction and comfort level in the management of gastroschisis. University of Iowa Hospitals and Clinics and the Carver College of Medicine, Iowa City, IA. A total of 49 third- and fourth-year medical students who were enrolled in the general surgery clerkship were eligible for this study. Enrollment into the study was completely voluntary. Of the 49 eligible students, 36 students agreed to participate in the study, and 27 completed the study. Mean scores for the Pre-Test MC, Post-Test MC, and Follow-Up MC were similar between the control and intervention groups.

    The objective was to test for significant differences in subjective and objective pretest probabilities for acute coronary syndrome (ACS) in a large cohort of chest pain patients stratified by race or gender. Secondarily we wanted to test for any differences in rates of ACS, rates of 90-day returns, cost, and chest radiation exposure after these stratifications. This is a secondary analysis of a prospective outcomes study of ED patients with chest pain and shortness of breath. We performed two separate analyses. The data set was divided by gender for analysis 1 while the analysis 2 stratification was made by race (nonwhite vs. white). For each analysis, groups were compared on several variables: provider visual analog scales (VAS) for likelihood of ACS, PREtest Consult ACS probabilities, rates of ACS, total radiation exposure to the chest, total costs at 30 days, and 90-day recidivism (ED, overnight observations, and inpatient admissions). A total of 844 patients were studied. Gender information was present on all 844 subjects, while complete race/ethnicity information was available on 783 (93%) subjects. For the first analysis, female patients made up 57% (478/844) of the population and their mean provider VAS scores for ACS were significantly lower (p = 0.000) at 14% (95% confidence interval [CI] = 13% to 16%) than that of males at 22% (95% CI = 19% to 24%). This was consistent with the objective pretest ACS probabilities subsequently calculated via the validated online tool, PREtest Consult, which were also significantly lower (p = 0.000) at 2.7% (95% CI = 2.4% to 3.1%) for females versus 6.6% (95% CI = 5.9% to 7.3%) for males. However, comparing females to males, there was no significant difference in diagnosis of ACS (3.6% vs. 1.6%), mean chest radiation doses (5.0 mSv vs. 4.9 mSv), total costs at 30 days ($3,451.24 vs. $3,847.68), or return to the ED within 90 days (26% each). For analysis 2 by race, nonwhite patients also comprised 57% (444/783) of

    To improve the clinical reasoning skills of postgraduate students in internal medicine through 2 kinds of extracurricular books: medical nonfiction and nonmedical fiction. Clinical reasoning is difficult to define, understand, observe, teach, and measure. This is an educational innovation under an experimental framework based on a cognitive intervention grounded in constructivist and cognitivist theories. This study was conducted from June 1, 2014, through May 31, 2015. It was a pre-post, randomized, controlled, prospective, mixed-methods, small-group study. The intervention was through medical nonfiction and nonmedical fiction books. The process was structured to ensure that the students would read the material in phases and reflect on them. Clinical reasoning (pretests and posttests) was quantitatively assessed using the Diagnostic Thinking Inventory (DTI) and clinical reasoning exercises (CREs) and their assessment using a rubric. A qualitative design was used, and face-to-face semistructured interviews were conducted. Posttest total scores (DTI=188.92; CREs=53.92) were higher for the study group after the intervention compared with its own pretest scores (DTI=165.25; CREs=41.17) and with the pretest (DTI=159.27; CRE=40.73) and posttest (DTI=166.91; CREs=41.18) scores of the control group. Interviews with the study group confirmed that the intervention was acceptable and useful in daily practice. We introduced, evaluated, and proved an approach to teaching-learning clinical reasoning based on the assumption that the clinical reasoning skills of postgraduate students in internal medicine can be enhanced through 2 kinds of extracurricular books and that fun as well as interest will enhance learning. This study is not only about teaching-learning clinical reasoning but also about the humanities in medical education. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    The effect of a course on self-awareness and communication techniques on nursing students' assertiveness and self-esteem was examined. The Rathus Assertiveness Schedule and Coopersmith Self-Esteem Inventory were used to measure assertiveness and self-esteem in second-year students in an undergraduate nursing school. Seventy-nine students completed the course. The study was designed as a pre-test and post-test study. A significant difference between assertiveness and self-esteem scores of students in pre-test and post-test measurements was found. There was a positive relationship between assertiveness and self-esteem. The course lasted 14 weeks for a total of 3 h per week. The teaching methods focused mostly on active student participation, demonstration, role play, experience and experience sharing, homework, constructive feedback, and watching films. These educational approaches should be evaluated in future studies and adopted in the curriculum. This study provides a basis for the development of learner-centred teaching methods.

    Full Text Available Background Hepatitis C virus (HCV is a major cause of chronic liver disease and cancer. Vietnamese Americans are at high risk of HCV infection, with men having the highest US incidence of liver cancer. This study examines an intervention to improve HCV knowledge among Vietnamese Americans. Study Seven Vietnamese community-based organizations in Pennsylvania and New Jersey recruited a total of 306 Vietnamese participants from 2010 to 2011. Results Average knowledge scores for pretest and posttest were 3.32 and 5.88, respectively (maximum 10. After adjusting for confounding variables, age and higher education were positively associated with higher pretest scores and having a physician who spoke English or Vietnamese was negatively associated with higher pretest scores. Additionally, after adjusting for confounding variables, household income, education, and having an HCV-infected family member significantly increased knowledge scores. Conclusions Promotion and development of HCV educational programs can increase HCV knowledge among race and ethnic groups, such as Vietnamese Americans. Giving timely information to at-risk groups provides the opportunity to correct misconceptions, decrease HCV risk behaviors, and encourage testing that might improve timely HCV diagnosis and treatment.

    A flipped classroom approach has been implemented in an undergraduate fluid mechanics course. Students watch short on-line videos before class, participate in active in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. In-class activities are designed to achieve a trifecta of: 1. developing problem solving skills, 2. learning subject content, and 3. developing inquiry skills. The instructor and assistants provide critical ``just-in-time tutoring'' during the in-class problem solving sessions. Comparisons are made with a simultaneous section offered in a traditional mode by a different instructor. Regression analysis was used to control for differences among students and to quantify the effect of the flipped fluid mechanics course. The dependent variable was the students' combined final examination and post-concept inventory scores and the independent variables were pre-concept inventory score, gender, major, course section, and (incoming) GPA. The R-square equaled 0.45 indicating that the included variables explain 45% of the variation in the dependent variable. The regression results indicated that if the student took the flipped fluid mechanics course, the dependent variable (i.e., combined final exam and post-concept inventory scores) was raised by 7.25 points. Interestingly, the comparison group reported significantly more often that their course emphasized memorization than did the flipped classroom group.

    The Motivated Strategies for Learning Questionnaire (MSLQ) purports to measure motivation using the expectancy-value model. Although it is widely used in other fields, this instrument has received little study in health professions education. The purpose of this study was to evaluate the validity of MSLQ scores. We conducted a validity study evaluating the relationships of MSLQ scores to other variables and their internal structure (reliability and factor analysis). Participants included 210 internal medicine and family medicine residents participating in a web-based course on ambulatory medicine at an academic medical centre. Measurements included pre-course MSLQ scores, pre- and post-module motivation surveys, post-module knowledge test and post-module Instructional Materials Motivation Survey (IMMS) scores. Internal consistency was universally high for all MSLQ items together (Cronbach's α = 0.93) and for each domain (α ≥ 0.67). Total MSLQ scores showed statistically significant positive associations with post-test knowledge scores. For example, a 1-point rise in total MSLQ score was associated with a 4.4% increase in post-test scores (β = 4.4; p motivation and satisfaction. Scores on MSLQ domains demonstrated associations that generally aligned with our hypotheses. Self-efficacy and control of learning belief scores demonstrated the strongest domain-specific relationships with knowledge scores (β = 2.9 for both). Confirmatory factor analysis showed a borderline model fit. Follow-up exploratory factor analysis revealed the scores of five factors (self-efficacy, intrinsic interest, test anxiety, extrinsic goals, attribution) demonstrated psychometric and predictive properties similar to those of the original scales. Scores on the MSLQ are reliable and predict meaningful outcomes. However, the factor structure suggests a simplified model might better fit the empiric data. Future research might consider how assessing and responding to motivation could enhance

    A study was conducted to: (1) evaluate the effect of a slide-tape program on patients' short-term and long-term knowledge about their bronchodilator medications; and (2) determine it any differences exist in learning or retention patterns for different content areas of drug information. The knowledge of 30 patients was measured using a randomized sequence of three comparable 15-question tests. The first test was given before the slide-tape program was presented, the second test within 24 hours, and the last test one to six months (mean = 2.8 months) later. Scores attained on the first posttest were significantly higher (p less than 0.001) than pretest scores. Learning differences among drug-information-content areas were not evidenced on the first posttest. No significant difference was demonstrated between scores on pretest and last posttest (p = 0.100). However, retention patterns among content areas were found to differ significantly (p less than 0.05). Carefully designed audiovisual programs can impart drug information to patients. Medication counseling should be repeated at appropriate opportunities because patients lose drug knowledge over time.

    Smith, Rachel Clara

    The field of physics is heavily male dominated in America. Thus, half of the population of our country is underrepresented and underserved. The identification of factors that contribute to gender disparity in physics is necessary for educators to address the individual needs of students, and, in particular, the separate and specific needs of female students. In an effort to determine if any correlations could be established or strengthened between sex, gender identity, social network, algebra skill, scientific reasoning ability, and/or student attitude, a study was performed on a group of 82 students in an introductory algebra based physics course. The subjects each filled out a survey at the beginning of the semester of their first semester of algebra based physics. They filled out another survey at the end of that same semester. These surveys included physics content pretests and posttests, as well as questions about the students' habits, attitudes, and social networks. Correlates of posttest score were identified, in order of significance, as pretest score, emphasis on conceptual learning, preference for male friends, number of siblings (negatively correlated), motivation in physics, algebra score, and parents' combined education level. Number of siblings was also found to negatively correlate with, in order of significance, gender identity, preference for male friends, emphasis on conceptual learning, and motivation in physics. Preference for male friends was found to correlate with, in order of significance, emphasis on conceptual learning, gender identity, and algebra score. Also, gender identity was found to correlate with emphasis on conceptual learning, the strongest predictor of posttest score other than pretest score.

    First aid is the helping behavior and initial care provided for an acute illness or injury. Students have the potential for changing the health scenario of the society if properly groomed and educated. The objective of the study is to evaluate the effectiveness of educational intervention on the first aid among middle school students of a rural school in West Bengal. A total of 230, 6 th and 7 th standard students were given a self-administered questionnaire for assessing their baseline knowledge about management of common injuries followed by educational intervention with a systematically devised teaching module during February to March 2016. Post intervention evaluation of their knowledge acquisition was done after 2 weeks with same questionnaire. The baseline knowledge on the management of selected injuries was found to be insufficient among the study subjects. Paired t -test was performed to compare the pre- and post-test scores of knowledge and attitude of the students about first aid, and there was a significant change in knowledge from pretest score (mean = 1.50, standard deviation [SD] =0.47) to posttest score (mean = 6.53, SD = 1.30). To quantify the effectiveness of health education, effect size (Cohen's d) was derived. For knowledge score, Cohen's d was 5.14 with large effect size indicating highly effective impact of the training program. Significant change was also noticed regarding attitude regarding first aid as evident from increase in pretest score (mean = 1.19, SD = 0.96) to posttest score (mean = 3.17, SD = 1.03); Cohen's d was 1.88 with medium effect size. Inculcating first-aid training in the school curriculum can be a fruitful investment in ensuring proper and timely management of illnesses and injuries not only for the school children but also for the community at large.

    Purpose: Anatomic considerations are often critical in multidisciplinary cancer care. We developed an anatomy-focused educational program for radiation oncology residents integrating cadaver dissection into the didactic review of diagnostic, surgical, radiologic, and treatment planning, and herein assess its efficacy. Methods and Materials: Monthly, anatomic-site based educational modules were designed and implemented during the 2008-2009 academic year at Duke University Medical Center. Ten radiation oncology residents participated in these modules consisting of a 1-hour didactic introduction followed by a 1-hour session in the gross anatomy lab with cadavers prepared by trained anatomists. Pretests and posttests were given for six modules, and post-module feedback surveys were distributed. Additional review questions testing knowledge from prior sessions were integrated into the later testing to evaluate knowledge retention. Paired analyses of pretests and postests were performed by Wilcoxon signed-rank test. Results: Ninety tests were collected and scored with 35 evaluable pretest and posttest pairs for six site-specific sessions. Posttests had significantly higher scores (median percentage correct 66% vs. 85%, p < 0.001). Of 47 evaluable paired pretest and review questions given 1-3 months after the intervention, correct responses rates were significantly higher for the later (59% vs. 86%, p = 0.008). Resident course satisfaction was high, with a median rating of 9 of 10 (IQR 8-9); with 1 being 'less effective than most educational interventions' and 10 being 'more effective than most educational interventions.' Conclusions: An integrated oncoanatomy course is associated with improved scores on post-intervention tests, sustained knowledge retention, and high resident satisfaction.

    The main goal of this study was the development of a reliable intervention to overcome general procrastination orientated to college students, designed to be used in practical clinical work. The workshops involved six meetings based on behavioral and cognitive techniques, paradox intervention, and psychoeducation. 175 students participated voluntarily. Their procrastination levels were measured in a pretest, post-test, and a 3-month follow-up. After the first interview, the participants were randomly divided into three groups (Intervention A, Intervention B, and a control group with no intervention). There was a significant improvement after the intervention. After 3 months, the average score was still significantly lower than in the pretest, whereas the score of the control group remained unchanged. The participants in Workshop A scored significantly lower in the post-test than the ones in Workshop B. After 3 months, the participants in Workshop B scored significantly lower in the follow up. So both interventions resulted to be effective in reducing procrastination sustainably.

    The Ventriloscope® (Lecat's SimplySim, Tallmadge, OH) is a modified stethoscope used as a simulation training device for auscultation. To test the effectiveness of the Ventriloscope as a training device in teaching heart and lung auscultatory findings to paramedic students. A prospective, single-hospital study conducted in a paramedic-teaching program. The standard teaching group learned heart and lung sounds via audiocassette recordings and lecture, whereas the intervention group utilized the modified stethoscope in conjunction with patient volunteers. Study subjects took a pre-test, post-test, and a follow-up test to measure recognition of heart and lung sounds. The intervention group included 22 paramedic students and the standard group included 18 paramedic students. Pre-test scores did not differ using two-sample t-tests (standard group: t [16]=-1.63, p=0.12) and (intervention group: t [20]=-1.17, p=0.26). Improvement in pre-test to post-test scores was noted within each group (standard: t [17]=2.43, p=0.03; intervention: t [21]=4.81, p<0.0001). Follow-up scores for the standard group were not different from pre-test scores of 16.06 (t [17]=0.94, p=0.36). However, follow-up scores for the intervention group significantly improved from their respective pre-test score of 16.05 (t [21]=2.63, p=0.02). Simulation training using a modified stethoscope in conjunction with standardized patients allows for realistic learning of heart and lung sounds. This technique of simulation training achieved proficiency and better retention of heart and lung sounds in a safe teaching environment. Copyright © 2012 Elsevier Inc. All rights reserved.

    The results of a post-test analysis of the integral system test P4, which has been executed in the PANDA facility at PSI in Switzerland within the framework of Work Package 2 of the TEPSS project are presented. The post-test analysis comprises an evaluation of the PANDA test P4 and a comparison of the test results with the results of simulations using the RELAPS/MOD3.2, TRAC-BF1, and MELCOR 1.8.4 codes. The PANDA test P4 has provided data about how trapped air released from the drywell later in the transient affects PCCS performance in an adequate manner. The well-defined measurements can serve as an important database for the assessment of thermal hydraulic system analysis codes, especially for conditions that could be met in passively operated advanced reactors, i.e. low pressure and small driving forces. Based on the analysis of the test data, the test acceptance criteria have been met. The test P4 has been successfully completed and the instrument readings were with the permitted ranges. The PCCs showed a favorable and robust performance and a wide margin for decay heat removal from the containment. The PANDA P4 test demonstrated that trapped air, released from the drywell later in the transient, only temporarily and only slightly affected the performance of the passive containment cooling system. The analysis of the results of the RELAPS code showed that the overall behaviour of the test has been calculated quite well with regards to pressure, mass flow rates, and pool boil-down. This accounts both for the pre-test and the post-test simulations. However, due to the one-dimensional, stacked-volume modeling of the PANDA DW, WW, and GDCS vessels, 3D-effects such as in-vessel mixing and recirculation could not be calculated. The post-test MELCOR simulation showed an overall behaviour that is comparable to RELAPS. However, MELCOR calculated almost no air trapping in the PCC tubes that could hinder the steam condensation rate. This resulted in lower calculated

    For a successful design and analysis of Sodium cooled Fast Reactor (SFR), it is required to have a reliable and well-proven system analysis code. To achieve this purpose, KAERI is enhancing the modeling capability of MARS code by adding the SFR-specific models such as pressure drop model, heat transfer model and reactivity feedback model. This version of MARS-LMR will be used as a basic tool in the design and analysis of future SFR systems in Korea. Before wide application of MARS-LMR code, it is required to verify and validate the code models through analyses for appropriate experimental data or analytical results. The end-of-life test of Phenix reactor performed by the CEA provided a unique opportunity to have reliable test data which is very valuable in the validation and verification of a SFR system analysis code. The KAERI joined this international program of the analysis of Phenix end-of-life natural circulation test coordinated by the IAEA from 2008. The main test of natural circulation was completed in 2009. Before the test the KAERI performed the pre-test analysis based on the design condition provided by the CEA. Then, the blind post-test analysis was also performed based on the test conditions measured during the test before the CEA provide the final test results. Finally, the final post-test analysis was performed recently to predict the test results as accurate as possible. This paper introduces the modeling approach of the MARS-LMR used in the final post-test analysis and summarizes the major results of the analysis

    The objectives of this study are to assess undergraduate awareness of cancer risk factors, prevention strategies, and warning signs and to evaluate whether an educational intervention increases cancer awareness. This study adopts a nonequivalent control group pretest-posttest design. Of the 386 students who completed the pretest, only 35-39 % identified low fruit and vegetable intake, being overweight, and physical inactivity as cancer risk factors, and cancer warning signs. After the educational intervention, the analysis of variance of changes from baseline (the pretest score) for all four experimental groups were all significantly higher than those of the two control groups (p ≤.001), except for the change of the retention test score from the pretest score for experimental group 3. This study highlights the need to improve undergraduates' cancer awareness and the effectiveness of educational intervention.

    Full Text Available The purpose of this study is to analyze the development of students’ reading comprehension skills about using cognitive strategies in foreign language teaching by means of awareness raising activities. To this end, the research was conducted for 11 weeks with 77 students studying in an English preparatory school program. The experimental group was exposed to a training which is based on awareness raising activities about using cognitive strategies. A pre-test and a post-test were designed for 2 experimental and 2 control groups with random sampling, and then the statistical differences were tested based on the scores of the both groups in terms of significance. Moreover, the study aims to determine the views of the participants about the strategy training. The results show that there was a significant difference between the pre-test and post-test scores of the experimental group in terms of their achievement in reading skill, and the post-test scores of the both experimental group and control group were in favor of the experimental group. Also, it has also found that the experiment had a positive impact on the participants.

    Method: The study used a cluster randomised control trial design. The study included 211 Grade 7 participants from schools in the Cape Town Metropole. The CCR intervention was administered to 97 participants in the experimental group, whilst 114 participants in the control group did not receive the intervention. The Stuttering Resource Outcome Measure(SROM used as the outcome measure during pre- and post-test period. STATISTICA was used for in-depth data analysis. Results: An overall positive direction of change in scores was observed for the experimental group compared with the control group. However, the magnitude of change in the experimental group was not statistically significant (p = 0.2683. Male and female participants did not differ significantly in their scores on the SROM across pre-test and post-test periods. Participants who had exposure to individuals who stutter had significantly more positive scores on the SROM in the pre-test and post-test periods compared to those who had no direct exposure to stuttering. Conclusion: This result indicated the beginning of positive attitude change which may be attributed to the intervention. Further investigation is warranted.

    A quasi-experimental, two-group pretest-post-test design was conducted to examine the effect of problem-based learning on the critical thinking skills of 46 Year 2 undergraduate nursing students in the People's Republic of China. The California Critical Thinking Skills Test Form A, Chinese-Taiwanese version was used as both a pretest and as a post-test for a semester-long nursing course. There was no significant difference in critical thinking skills at pretest, whereas, significant differences in critical thinking skills existed between the problem-based learning and lecture groups at post-test. The problem-based learning students had a significantly greater improvement on the overall California Critical Thinking Skills Test, analysis, and induction subscale scores compared with the lecture students. Problem-based learning fostered nursing students' critical thinking skills.

    This study compared the effectiveness of three approaches to improving visual perception among preschool children 4-6 years old with developmental delays: multimedia visual perceptual group training, multimedia visual perceptual individual training, and paper visual perceptual group training. A control group received no special training. This study employed a pretest-posttest control group of true experimental design. A total of 64 children 4-6 years old with developmental delays were randomized into four groups: (1) multimedia visual perceptual group training (15 subjects); (2) multimedia visual perceptual individual training group (15 subjects); paper visual perceptual group training (19 subjects); and (4) a control group (15 subjects) with no visual perceptual training. Forty minute training sessions were conducted once a week for 14 weeks. The Test of Visual Perception Skills, third edition, was used to evaluate the effectiveness of the intervention. Paired-samples t-test showed significant differences pre- and post-test among the three groups, but no significant difference was found between the pre-test and post-test scores among the control group. ANOVA results showed significant differences in improvement levels among the four study groups. Scheffe post hoc test results showed significant differences between: group 1 and group 2; group 1 and group 3; group 1 and the control group; and group 2 and the control group. No significant differences were reported between group 2 and group 3, and group 3 and the control group. The results showed all three therapeutic programs produced significant differences between pretest and posttest scores. The training effect on the multimedia visual perceptual group program and the individual program was greater than the developmental effect Both the multimedia visual perceptual group training program and the multimedia visual perceptual individual training program produced significant effects on visual perception.

    Caregivers who work in community living arrangements or intermediate care facilities are responsible for the oral hygiene of individuals with intellectual and developmental disabilities. Oral hygiene training programs do not exist in many organizations, despite concerns about the oral care of this population. The purpose of this study was to determine the effectiveness of a caregiver educational program. This study used a quasi-experimental one-group pretest/posttest design with repeated measures to describe the outcomes of an educational program. Program participants demonstrated oral hygiene skills on each other while being scored by a trained observer, after which they completed an oral hygiene compliance survey. After three months, a follow-up included the same posttest, demonstration of oral hygiene skills, and repeat of the compliance survey. Paired-sample t-tests of oral hygiene knowledge showed a statistically significant improvement from pretest to posttest and from pretest to three-month posttest. Oral hygiene skills and compliance improved. Results demonstrate evidence that caregiver education improves knowledge, skill, and compliance in oral hygiene. Further studies are required to demonstrate the value of providing oral hygiene education and training for caregivers of individuals with intellectual and developmental disabilities.

    Full Text Available Designing the perfect survey questionnaire is impossible. However, researchers can still create an effective research. To make your questionnaire effective, it is necessary to pretest it before actually using it. The following paper reveals some general guidelines on pretesting and what to do for a more effective marketing research giving the fact that the existing literature highlights the importance and indispensability of pretesting and on the other hand, does not provide sufficient information in terms of methodology about it. Also, we have tried to explain the importance of questionnaires pretesting before applying them in order to obtain the best results in marketing research and we’ve kept in mind that high quality in this domain means using new tools and improving the existing ones if one searches for efficient results.

    The teaching and learning of games and sport-based activities has historically been the dominant form of the physical education curricula. With an interest in providing to students meaningful and culturally situated sporting experiences, Sport Education is probably the most implemented and researched pedagogical model worldwide. However, although there is considerable evidence that the model as a curriculum approach can benefit the development of social goals and healthy sport behaviors, not a single study as to date examined students' game-play development beyond participation in single and isolated teaching units. Therefore, the purpose of this study was to examine students' development of Game Performance and Game Involvement during participation in three consecutive Sport Education seasons of invasion games. The participants were an experienced physical education teacher and one seventh-grade class totaling 26 students (10 girls and 16 boys). Using the Game Performance Assessment Instrument (Oslin et al., 1998), pre-test to post-tests measures of students' Game Performance and Game Involvement were collected during their participation in basketball (20 lessons), handball (16 lessons), and football (18 lessons) units. Inter-group differences and pre-test to post-test improvements within each season were analyzed through 2 (time) x group (sport) repeated measures ANOVA tests. There were found significant pre-test to post-test improvements in Game Performance and Game Involvement in the second (handball) and third (football) seasons, but not in the first season (basketball). Students' Game Performance and Involvement scores of handball and football were significantly higher than their scores while playing basketball. The opportunity for an extended engagement in game-play activities and prolonged membership of students in the same teams throughout three consecutive seasons of Sport Education were key to the outcomes found. The specific configurations of the game

    To assess the utility of a multiple-encounter in-situ (MEIS) simulation as an orientation tool for multidisciplinary staff prior to opening a new paediatric emergency service. A single-group pretest/post-test study was conducted. During the MEIS simulation, multidisciplinary staff with participant or observer roles managed eight children (mannequins) who attended triage with their parent/guardians (clinical facilitators) for a range of emergency presentations (structured scenarios designed to represent the expected range of presentations plus test various clinical pathways/systems). Participants were debriefed to explore clinical, systems and crisis-resource management issues. Participants also completed a pre-intervention and post-intervention questionnaire comprising statements about role confidence and orientation adequacy. Pre-test and post-test results were analysed using t-test and Wilcoxon signed rank test. Eighty-nine staff participated in the MEIS simulation, with the majority completing the pre-simulation and post-simulation questionnaire. There was a significant improvement in post-intervention versus pre-intervention Likert scores for role confidence and orientation adequacy (p=0.001 and orientation adequacy. Nearly all scenarios resulted in significant increases in participants' confidence levels. The MEIS simulation was of utility in orientation of staff, at least with respect to self-reported role confidence and orientation adequacy. Its effectiveness in practice or compared with other orientation techniques was not assessed, but it did identify several flaws in planned systems allowing remediation prior to opening.

    This study examined the effectiveness of a series of Web-based, multimedia tutorials on methods of human body composition analysis. Tutorials were developed around four body composition topics: hydrodensitometry (underwater weighing), dual-energy X-ray absorptiometry, bioelectrical impedance analysis, and total body electrical conductivity. Thirty-two students enrolled in the course were randomly assigned to learn the material through either the Web-based tutorials only ("Computer"), a traditional lecture format ("Lecture"), or lectures supplemented with Web-based tutorials ("Both"). All students were administered a validated pretest before randomization and an identical posttest at the completion of the course. The reliability of the test was 0.84. The mean score changes from pretest to posttest were not significantly different among the groups (65.4 plus minus 17.31, 78.82 plus minus 21.50, and 76 plus minus 21.22 for the Computer, Both, and Lecture groups, respectively). Additionally, a Likert-type assessment found equally positive attitudes toward all three formats. The results indicate that Web-based tutorials are as effective as the traditional lecture format for teaching these topics.

    Full Text Available One of the most important milestones in the development of theory of mind is the understanding of false beliefs. This study compares children’s understanding of representational change and others’ false beliefs and evaluates the effectiveness of an appearance-reality training for improving children’s false belief understanding. A total of 78 children ranging in age from 41 to 47 months were trained in three sessions and evaluated in a pretest and in a posttest. The results show that for children it is easier to understand representational change than false beliefs in others, and that the improvement after training was greater when starting from a higher score in the pretest. The implications of this for training in false belief understanding are discussed.

    This study examined the efficacy of a Tier 2 kindergarten mathematics intervention program, ROOTS, focused on developing whole number understanding for students at risk in mathematics. A total of 29 classrooms were randomly assigned to treatment (ROOTS) or control (standard district practices) conditions. Measures of mathematics achievement were collected at pretest and posttest. Treatment and control students did not differ on mathematics assessments at pretest. Gain scores of at-risk intervention students were significantly greater than those of control peers, and the gains of at-risk treatment students were greater than the gains of peers not at risk, effectively reducing the achievement gap. Implications for Tier 2 mathematics instruction in a response to intervention (RtI) model are discussed. © Hammill Institute on Disabilities 2014.

    Although the testing effect has received a substantial amount of empirical attention, such research has largely focused on the effects of tests given after study. The present research examines the effect of using tests prior to study (i.e., as pretests), focusing particularly on how pretesting influences the subsequent learning of information that is not itself pretested but that is related to the pretested information. In Experiment 1, we found that multiple-choice pretesting was better for the learning of such related information than was cued-recall pretesting or a pre-fact-study control condition. In Experiment 2, we found that the increased learning of non-pretested related information following multiple-choice testing could not be attributed to increased time allocated to that information during subsequent study. Last, in Experiment 3, we showed that the benefits of multiple-choice pretesting over cued-recall pretesting for the learning of related information persist over 48 hours, thus demonstrating the promise of multiple-choice pretesting to potentiate learning in educational contexts. A possible explanation for the observed benefits of multiple-choice pretesting for enhancing the effectiveness with which related nontested information is learned during subsequent study is discussed.

    We hypothesized that Theory of Planned Behavior (TPB) constructs (behavioral belief, attitude, subjective norm, perceived behavioral control, knowledge and behavioral intention) regarding preventive behaviors for obesity and type 2 diabetes will change favorably after completing the web-based intervention, HOT (Healthy Outcome for Teens) project, grounded in the TPB; and that passive online learning (POL) group will improve more than the active online learning (AOL) group. The secondary hypothesis was to determine to what extent constructs of the TPB predict intentions. 216 adolescents were recruited, 127 randomly allocated to the treatment group (AOL) and 89 to the control group (POL). The subjects completed a TPB questionnaire pre and post intervention. Both POL and AOL groups showed significant improvements from pretest to posttest survey. However, the results indicated no significant difference between POL and AOL for all constructs except behavioral belief. Correlational analysis indicated that all TPB constructs were significantly correlated with intentions for pretest and posttest for both groups. Attitude and behavioral control showed strongest correlations. Regression analysis indicated that TPB constructs were predictive of intentions and the predictive power improved post intervention. Behavioral control consistently predicted intentions for all categories and was the strongest predictor for pretest scores. For posttest scores, knowledge and attitude were the strongest predictors for POL and AOL groups respectively. Thus, HOT project improved knowledge and the TPB constructs scores for targeted behaviors, healthy eating and physical activity, for prevention of obesity and type 2 diabetes.

    The flipped classroom has been proposed as an alternative curricular approach to traditional didactic lectures but has not been previously applied to a surgery clerkship. A 1-year prospective cohort of students (n = 89) enrolled in the surgery clerkship was taught using a flipped classroom approach. A historical cohort of students (n = 92) taught with a traditional lecture curriculum was used for comparison. Pretest and post-test performance, end-of-clerkship surveys, and National Board of Medical Examiners (NBME) scores were analyzed to assess effectiveness. Mean pretest and post-test scores increased across all modules (P flipped classroom contributed to this increase. Implementation of a flipped classroom in the surgery clerkship is feasible and results in high learner satisfaction, effective knowledge acquisition, and increased career interest in surgery with noninferior NBME performance.

    The objective of our study was to assess whether high-fidelity simulation-based training is more effective than traditional didactic lecture to train radiology residents in the management of contrast reactions. This was a prospective study of 44 radiology residents randomized into a simulation group versus a lecture group. All residents attended a contrast reaction didactic lecture. Four months later, baseline knowledge was assessed with a written test, which we refer to as the "pretest." After the pretest, the 21 residents in the lecture group attended a repeat didactic lecture and the 23 residents in the simulation group underwent high-fidelity simulation-based training with five contrast reaction scenarios. Next, all residents took a second written test, which we refer to as the "posttest." Two months after the posttest, both groups took a third written test, which we refer to as the "delayed posttest," and underwent performance testing with a high-fidelity severe contrast reaction scenario graded on predefined critical actions. There was no statistically significant difference between the simulation and lecture group pretest, immediate posttest, or delayed posttest scores. The simulation group performed better than the lecture group on the severe contrast reaction simulation scenario (p = 0.001). The simulation group reported improved comfort in identifying and managing contrast reactions and administering medications after the simulation training (p ≤ 0.04) and was more comfortable than the control group (p = 0.03), which reported no change in comfort level after the repeat didactic lecture. When compared with didactic lecture, high-fidelity simulation-based training of contrast reaction management shows equal results on written test scores but improved performance during a high-fidelity severe contrast reaction simulation scenario.

    Full Text Available Abstract Background Simulation training has potential in developing clinical skills in pre-clinical medical students, but there is little evidence on its effectiveness. Methods Twenty four first year graduate entry preclinical medical students participated in this crossover study. They were divided into two groups, one performed chest examination on each other and the other used SimMan. The groups then crossed over. A pretest, midtest and post-test was conducted in which the students answered the same questionnaire with ten questions on knowledge, and confidence levels rated using a 5 point Likert scale. They were assessed formatively using the OSCE marking scheme. At the end of the session, 23 students completed a feedback questionnaire. Data was analyzed using one-way ANOVA and independent t-test. Results When the two groups were compared, there was no significant difference in the pretest and the post-test scores on knowledge questions whereas the midtest scores increased significantly (P Mean confidence ratings increased from the pretest to midtest and then further in the post-test for both groups. Their confidence ratings increased significantly in differentiating between normal and abnormal signs [Group starting with SimMan, between pretest and midtest (P= 0.01 and group starting with peer examination, between midtest and post-test (P=0.02]. When the students’ ability to perform examination on each other for both groups was compared, there was a significant increase in the scores of the group starting with SimMan (P=0.007. Conclusions This pilot study demonstrated a significant improvement in the students’ knowledge and competence to perform chest examination after simulation with an increase in the student’s perceived levels of confidence. Feedback from the students was extremely positive. SimMan acts as a useful adjunct to teach clinical skills to preclinical medical students by providing a simulated safe environment and thus aids

    Geriatric depression is a major public health problem in China. The study compared the intervention and follow-up effects of aromatherapy massage and inhalation on symptoms of depression in community-dwelling older adults after an 8-week intervention. A prospective, randomized controlled trial was conducted on community-dwelling adults ≥60 years old, with symptoms of depression. Participants were randomly assigned, by Latin Square, to aromatherapy massage, inhalation, or control groups (each n = 20). The aromatherapy massage group received 30 min of aromatherapy massage with 5 mL oil, twice weekly for 8 weeks. The oil contained 50 μL (one drop) of compound essential oils (lavender [Lavandula angustifolia], sweet orange [Citrus sinensis], and bergamot (Citrus bergamia in a 2:1:1 ratio)], diluted in sweet almond oil to a concentration of 1%. The aromatherapy inhalation group received 30 min of nasal inhalation of 50 μL of the compound essential oils blended in 10 mL of purified water, twice weekly for 8 weeks. The control group received no intervention. The Geriatric Depression Scale Short Form (GDS-SF) and Patient Health Questionnaire-9 (PHQ-9) were used for assessment at pretest, posttest, and 6- and 10-week follow-ups in all groups. 5-Hydroxytryptamine (5-HT) concentration was assessed pretest and posttest. Postintervention, the aromatherapy massage and inhalation groups demonstrated significantly lower GDS-SF and PHQ-9 scores than control participants. Compared with the pretest, the GDS-SF and PHQ-9 scores for depressive symptoms in both experimental groups remained lower at posttest (8 weeks), 6-week (14 weeks), and 10-week (18 weeks) follow-ups. However, the GDS-SF and PHQ-9 scores did not differ among the four time points in the control group. The posttest 5-HT concentrations in the aromatherapy massage and inhalation groups were increased over pretest values. Both aromatherapy massage and aromatherapy inhalation may have important

    Davis, Edward

    This study investigated the relationship between an after-school tutorial program for African American high school students at a Title I school and scores on the science portion of the High School Graduation Examination (HSGE). Passing the examination was required for graduation. The target high school is 99% African American and the passing rate of the target high school was 42%---lower than the state average of 76%. The purpose of the study was to identify (a) the relationship between a science tutorial program and scores on the science portion of the HSGE, (b) the predictors of tutoring need by analyzing the relationship between biology grades and scores on the science portion of the HSGE, and (c) the findings between biology grades and scores on the science portion of the HSGE by analyzing the relationship between tutorial attendance and HSGE scores. The study was based on Piaget's cognitive constructivism, which implied the potential benefits of tutorials on high-stakes testing. This study used a 1-group pretest-posttest, quantitative methodology. Results showed a significant relationship between tutoring and scores on the biology portion of the HSGE. Results found no significant relationship between the tutorial attendance and the scores on the biology portion of the HSGE or between the biology grades and scores on the biology portion of the HSGE before tutoring. It has implications for positive social change by providing educational stakeholders with empirically-based guidance in determining the potential benefit of tutorial intervention strategies on high school graduation examination scores.

    Full Text Available Abstract Background Two trials were conducted to compare emergency department patient comprehension of rapid HIV pre-test information using different methods to deliver this information. Methods Patients were enrolled for these two trials at a US emergency department between February 2005 and January 2006. In Trial One, patients were randomized to a no pre-test information or an in-person discussion arm. In Trial Two, a separate group of patients were randomized to an in-person discussion arm or a Tablet PC-based video arm. The video, "Do you know about rapid HIV testing?", and the in-person discussion contained identical Centers for Disease Control and Prevention-suggested pre-test information components as well as information on rapid HIV testing with OraQuick®. Participants were compared by information arm on their comprehension of the pre-test information by their score on a 26-item questionnaire using the Wilcoxon rank-sum test. Results In Trial One, 38 patients completed the no-information arm and 31 completed the in-person discussion arm. Of these 69 patients, 63.8% had twelve years or fewer of formal education and 66.7% had previously been tested for HIV. The mean score on the questionnaire for the in-person discussion arm was higher than for the no information arm (18.7 vs. 13.3, p ≤ 0.0001. In Trial Two, 59 patients completed the in-person discussion and 55 completed the video arms. Of these 114 patients, 50.9% had twelve years or fewer of formal education and 68.4% had previously been tested for HIV. The mean score on the questionnaire for the video arm was similar to the in-person discussion arm (20.0 vs. 19.2; p ≤ 0.33. Conclusion The video "Do you know about rapid HIV testing?" appears to be an acceptable substitute for an in-person pre-test discussion on rapid HIV testing with OraQuick®. In terms of adequately informing ED patients about rapid HIV testing, either form of pre-test information is preferable than for patients

    Successful implementation of non-small cell lung cancer (NSCLC) evidence-based guideline recommendations requires effective educational programs that target all clinicians from interdisciplinary teams. This study describes and evaluates the Engaging an Interdisciplinary Team for NSCLC (GAIN 3.0) experiential learning-based educational curriculum. GAIN 3.0 was designed to enhance interdisciplinary collaboration for effective NSCLC diagnosis, assessment, and treatment. The program used a flipped classroom model that included an e-learning component prior to a live 6-hour interactive program. The interactive program included hands-on simulations, small group workshops, gamification, and case discussions. Participants included academic and community members of multidisciplinary lung cancer teams. Assessments included an online baseline survey, a pretest and posttest, a program evaluation, a long-term survey (LTS), and on-site faculty evaluation of participants. Of 416 attendees to 13 live GAIN 3.0 programs (nine in the United States and four in Europe), 304 (73%) completed the pretest and 187 (45%) completed the posttest. Out of a perfect score of 12 points, program participants had a mean test score of 6.3 ± 2.1 on the pretest (52%) and 7.8 ± 2.1 on the posttest (65%) (P = .03). There was an overall knowledge increase of 13% from pretest to posttest. Most LTS respondents (65%) rated the GAIN 3.0 live programs as "high impact." On the LTS, the areas with the greatest gains in participants who had very high confidence were communication across disciplines, use of a team-based approach, and personalized treatment. GAIN 3.0 was a highly successful interdisciplinary activity that improved participants' knowledge, competence, and likely the clinical care provided to patients with NSCLC.

    People with sickle cell disease (SCD) or sickle cell trait (SCT) may not have information about genetic inheritance needed for making informed reproductive health decisions. CHOICES is a Web-based, multimedia educational intervention that provides information about reproductive options and consequences to help those with SCD or SCT identify and implement an informed parenting plan. Efficacy of CHOICES compared with usual care must be evaluated. The purpose was to compare immediate posttest effects of CHOICES versus an attention-control usual care intervention (e-Book) on SCD-/SCT-related reproductive health knowledge, intention, and behavior. In a randomized controlled study, we recruited subjects with SCD/SCT from clinics, community settings, and online networks with data collected at sites convenient to the 234 subjects with SCD (n = 136) or SCT (n = 98). Their ages ranged from 18 to 35 years; 65% were women, and 94% were African American. Subjects completed a measure of sickle cell reproductive knowledge, intention, and behavior before and immediately after the intervention. Compared with the e-Book group, the CHOICES group had significantly higher average knowledge scores and probability of reporting a parenting plan to avoid SCD or SCD and SCT when pretest scores were controlled. Effects on intention and planned behavior were not significant. The CHOICES group showed significant change in their intention and planned behavior, whereas the e-Book group did not show significant change in their intention, but their planned behavior differed significantly. Initial efficacy findings are encouraging but warrant planned booster sessions and outcome follow-ups to determine sustained intervention efficacy on reproductive health knowledge, intention, and actual behavior of persons with SCD/SCT.

    Full Text Available As a stressful profession, nursing deals with different aspects of human health and illness, and stress can threaten nurses’ health and performance. As a result, using preventive stress management programs seems necessary. The present study aimed to evaluate the effectiveness of cognitive–behavioral stress management training in improving psychological symptoms (stress, anxiety, and depression and quality of life in nurses. The design of this study was quasi-experimental with pretest-posttest and a control group. The statistical population comprised all nurses working in Bandar Abbas Shari'ati Hospital. The study sample included all 30 nurses selected through convenience sampling method. They equally and randomly were divided into experiment and control groups. Depression, anxiety, and stress scale and the Farsi version of WHOQOL-BREF were used to collect data. The results showed there was a significant difference between pretest and posttest of experimental group in the mean scores of stress, anxiety, and quality of life; however, there was no significant difference in depression. Control group mean scores did not show a significant difference between pretest and posttest. There was no significant difference between the control and experimental groups before intervention in stress, anxiety, depression, and quality of life. The findings of this study suggest that, as a useful clinical intervention, stress management skill training is an effective way to improve mental distress and quality of life.

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards

      In team handball, an anterior cruciate ligament injury often occurs during landing after a jump shot. Many intervention programs try to reduce the injury rate by instructing athletes to land more safely. Video is an effective way to provide feedback, but little is known about its influence on landing technique in sport-specific situations.   To test the effectiveness of a video-overlay feedback method on landing technique in elite handball players.   Controlled laboratory study.   Laboratory.   A total of 16 elite female handball players assigned to a control group (n = 8; age = 17.61 ± 1.34 years, height = 1.73 ± 0.06 m, mass = 69.55 ± 4.29 kg) or video group (n = 8; age = 17.81 ± 0.86 years, height = 1.71 ± 0.03 m, mass = 64.28 ± 6.29 kg).   Both groups performed jump shots in a pretest, 2 training sessions, and a posttest. The video group received video feedback of an expert model with an overlay of their own jump shots in training sessions 1 and 2, whereas the control group did not.   We measured ankle, knee, and hip angles in the sagittal plane at initial contact and peak flexion; range of motion; and Landing Error Scoring System (LESS) scores. One 2 × 4 repeated-measures analysis of variance was conducted to analyze the group, time, and interaction effects of all kinematic outcome measures and the LESS score.   The video group improved knee and hip flexion at initial contact and peak flexion and range of motion. In addition, the group's average peak ankle flexion (12.0° at pretest to 21.8° at posttest) and LESS score (8.1 pretest to 4.0 posttest) improved. When we considered performance variables, no differences between groups were found in shot accuracy or vertical jump height, whereas horizontal jump distance in the video group increased over time.   Overlay visual feedback is an effective method for improving landing kinematics during a sport-specific jump shot. Further research is warranted to determine the long-term effects

  7. Characterizing the gender gap in introductory physics

    Previous research [S. J. Pollock , Phys. Rev. ST Phys. Educ. Res. 3, 1 (2007)] showed that despite the use of interactive engagement techniques, the gap in performance between males and females on a conceptual learning survey persisted from pretest to post-test at the University of Colorado at Boulder. Such findings were counter to previously published work [M. Lorenzo , Am. J. Phys. 74, 118 (2006)]. This study begins by identifying a variety of other gender differences. There is a small but significant difference in the course grades of males and females. Males and females have significantly different prior understandings of physics and mathematics. Females are less likely to take high school physics than males, although they are equally likely to take high school calculus. Males and females also differ in their incoming attitudes and beliefs about physics. This collection of background factors is analyzed to determine the extent to which each factor correlates with performance on a conceptual post-test and with gender. Binned by quintiles, we observe that males and females with similar pretest scores do not have significantly different post-test scores (p>0.2) . The post-test data are then modeled using two regression models (multiple regression and logistic regression) to estimate the gender gap in post-test scores after controlling for these important prior factors. These prior factors account for about 70% of the observed gender gap. The results indicate that the gender gap exists in interactive physics classes at our institution but is largely associated with differences in previous physics and math knowledge and incoming attitudes and beliefs.

    There is some consensus on the value of cognitive-behaviourally informed interventions in the criminal justice system, but uncertainty about which components are of critical value. To test the hypothesis that change in prisoners - criminal thinking and institutional misconduct - will both follow completion of a brief cognitive behavioural intervention. A one-group pre-test-post-test quasi-experimental design was used to assess change on the General Criminal Thinking (GCT) scale of the Psychological Inventory of Criminal Thinking Styles among 219 male prisoners completing a 10-week cognitive behavioural intervention, referred to as 'Lifestyle Issues'. Institutional misconduct was measured for 1 year prior to completion of the course and 2 years subsequently. Using variable-oriented analysis, post-test GCT scores were compared with change in prison conduct, controlling for the pre-test thinking scores. Calculations were repeated by using person-oriented analysis. Prisoners who displayed a drop in GCT scores between pre-test and post-test levels were significantly more likely to show a reduction in prison misconduct, whereas prison misconduct was likely to escalate among those who displayed a rise in criminal thinking scores from pre-test to post-test. These findings must still be regarded as preliminary, but taken together with other work and with cognitive behavioural theory, they suggest that development of more prosocial thinking and abilities may have an early beneficial effect on institutional behaviour. Their measurement may offer a practical way in which men could be assessed for readiness to return to the community. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called "SARMAD" to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD) during 6 weeks and discussed. Then, students participated in a post-test. Students' perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001); but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128). In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

    Full Text Available Background and purpose: Residents across the world spend several hours every week teaching medical students and junior residents. Workshops developed with the aim of improving resident teaching skills are becoming increasingly common in the various fields of medicine. The objectives of this study were to evaluate the effect of a resident-as-teacher educational intervention on the resident’s knowledge of medical education.Methods: The study was performed in SUMS, Iran, in 2010-2011 on all the junior residents from the different fields, including 104 men and 66 women. For data collection, a questionnaire (pre-test, post-test was used with 40 questions on medical education. The data were analyzed using descriptive statistics, tables and t test employing the SPSS software.Results: In total, 120 participants completed the questionnaires. According to the pre-test and post-test results, residents received extremely low scores in different subjects before the course implementation, whereas after it was implemented their scores had significantly increased fairly well. The comparison between the participants, average scores before and after the program indicates that the "resident-as-a-teacher, researcher and role model" course has been meaningful and significantly effective in improving their knowledge in this area.Conclusions: A few residency programs had instituted the resident teacher training curricula. A resident teacher training workshop was perceived as beneficial by the residents, and they reported improvement in their teaching skills.Keywords: EFFECTIVENSS, RESIDENTS AS TEACHERS, NOVEL PROGRAM

    2014-04-01

    Four groups of postsecondary students, 25 who were deaf/hard of hearing (D/HH), 25 with a learning disability, 25 who were English language learners (ELLs), and 25 without an identified disability studied notes that included text and graphical information based on a physics or a marine biology lecture. The latter 3 groups were normally hearing. All groups had higher scores on post- than on pretests for each lecture, with each group showing generally similar gains in amount of material learned from the pretest to the posttest. For each lecture, the D/HH students scored lower on the pre- and posttests than the other 3 groups of participants. Results indicated that students acquired measurable amounts of information from studying these types of notes for relatively short periods and that the notes have equal potential to support the acquisition of information by each of these groups of students.

    Best practice strategies for helping students learn the reasoning skills of problem solving and critical thinking (CT) remain a source of conjecture, particularly with regard to CT. The dental education literature is fundamentally devoid of research on the cognitive components of clinical decision-making. This study was aimed to develop and evaluate the impact of blended learning module on clinical decision-making skills of dental graduates for planning prosthodontics rehabilitation. An interactive teaching module consisting of didactic lectures on clinical decision-making and a computer-assisted case-based treatment planning software was developed Its impact on cognitive knowledge gain in clinical decision-making was evaluated using an assessment involving problem-based multiple choice questions and paper-based case scenarios. Mean test scores were: Pretest (17 ± 1), posttest 1 (21 ± 2) and posttest 2 (43 ± 3). Comparison of mean scores was done with one-way ANOVA test. There was overall significant difference in between mean scores at all the three points (P posttest 1 > pretest. Blended teaching methods employing didactic lectures on the clinical decision-making as well as computer assisted case-based learning can be used to improve quality of clinical decision-making in prosthodontic rehabilitation for dental graduates.

    Improvement of the interaction between forensic mental health nurses and patients may lead to a reduction of inpatient violence. The concept under study is detached concern, which refers to nurses' skills to neutralize the emotional appeal of patients by a balanced attitude between objectivity and emotional involvement. The Patient Contact Questionnaire (PCQ) aims at measuring the degree of concern of nurses for their patients. The PCQ was applied in a pretest-posttest design, evaluating the effects of the Early Recognition Method (ERM). This method aims at the prevention of inpatient violence in forensic psychiatry. Subjects were 116 forensic mental heath nurses working on 16 wards of a large Dutch forensic hospital. First, the baseline scores were compared to scores reported in an earlier study conducted in general psychiatry. Second, pretest-posttest comparisons were carried out for all nurses, and for subgroups of nurses with regard to gender, educational level, years of working experience, and patient population. Third, pretest-posttest comparisons were made on the PCQ item level. The baseline scores of male nurses indicated significantly higher levels of concern than those of female nurses. In addition, more experienced nurses scored significantly higher with regard to concern than less experienced nurses. When comparing the scores before and after applying ERM, no significant differences were found. However, the sores of female nurses showed a tendency toward more concern after implementation of ERM. Detached concern may be a meaningful concept in forensic mental health nursing in measuring nurses' concern for their patients. Levels of detached concern did not change significantly after application of ERM. However, the application of the PCQ could contribute to a better understanding of the interaction between nurses and their patients. 2010 Elsevier Inc. All rights reserved.

    2016-04-01

    Currently, many undergraduate nursing courses use blended-learning course formats with success; however, little evidence exists that supports the use of blended formats in introductory pathophysiology courses. The purpose of this study was to compare the scores on pre- and posttests and course satisfaction between traditional and blended course formats in an introductory nursing pathophysiology course. This study used a quantitative, quasi-experimental, nonrandomized control group, pretest-posttest design. Analysis of covariance compared pre- and posttest scores, and a t test for independent samples compared students' reported course satisfaction of the traditional and blended course formats. Results indicated that the differences in posttest scores were not statistically significant between groups. Students in the traditional group reported statistically significantly higher satisfaction ratings than students in the blended group. The results of this study support the need for further research of using blended learning in introductory pathophysiology courses in undergraduate baccalaureate nursing programs. Further investigation into how satisfaction is affected by course formats is needed. Copyright 2016, SLACK Incorporated.

    Background: Radiation therapy treatment planning has advanced over the past 2 decades, with increased emphasis on 3-dimensional imaging for target and organ-at-risk (OAR) delineation. Recent studies suggest a need for improved resident instruction in this area. We developed and evaluated an intensive national educational course (“boot camp”) designed to provide dedicated instruction in site-specific anatomy, radiology, and contouring using a multidisciplinary (MDT) approach. Methods: The anatomy and radiology contouring (ARC) boot camp was modeled after prior single-institution pilot studies and a needs-assessment survey. The boot camp incorporated joint lectures from radiation oncologists, anatomists, radiologists, and surgeons, with hands-on contouring instruction and small group interactive seminars using cadaveric prosections and correlative axial radiographs. Outcomes were evaluated using pretesting and posttesting, including anatomy/radiology multiple-choice questions (MCQ), timed contouring sessions (evaluated relative to a gold standard using Dice similarity metrics), and qualitative questions on satisfaction and perceived effectiveness. Analyses of pretest versus posttest scores were performed using nonparametric paired testing. Results: Twenty-nine radiation oncology residents from 10 Canadian universities participated. As part of their current training, 29%, 75%, and 21% receive anatomy, radiology, and contouring instruction, respectively. On posttest scores, the MCQ knowledge scores improved significantly (pretest mean 60% vs posttest mean 80%, P<.001). Across all contoured structures, there was a 0.20 median improvement in students' average Dice score (P<.001). For individual structures, significant Dice improvements occurred in 10 structures. Residents self-reported an improved ability to contour OARs and interpret radiographs in all anatomic sites, 92% of students found the MDT format effective for their learning, and 93% found the boot camp

    To measure academic achievement of the multiple intelligence-based learning medium via a tablet device. This is a quasi-experimental research study (non-randomized control group pretest-posttest design) in 62 grade 1 elementary students (33 males and 29 females). Thirty-one students were included in an experimental group using purposive sampling by choosing a student who had highest multiple intelligence test scores in logical-mathematic. Then, this group learned by the new learning medium via a tablet which the application matched to logical-mathematic multiple intelligence. Another 31 students were included in a control group using simple random sampling and then learning by recitation. Both groups did pre-test and post-test vocabulary. Thirty students in the experimental group and 24 students in the control group increased post-test scores (odds ratio = 8.75). Both groups made significant increasing in post-test scores. The experimental group increased 9.07 marks (95% CI 8.20-9.93) significantly higher than the control group which increased 4.39 marks (95% CI 3.06-5.72) (t = -6.032, df = 51.481, p learning from either multiple intelligence-based learning medium via a tablet or recitation can contribute academic achievement, learningfrom the new medium contributed more achievement than recitation. The new learning medium group had higher post-test scores 8.75 times than the recitation group. Therefore, the new learning medium is more effective than the traditional recitation in terms of academic achievement. This study has limitations because samples came from the same school. However, the previous study in Thailand did notfind a logical-mathematical multiple intelligence difference among schools. In the future, long-term research to find how the new learning medium affects knowledge retention will support the advantage for life-long learning.

    Medical simulation has been used to teach critical illness in a variety of settings. This study examined the effect of didactic lectures compared with simulated case scenario in a medical simulation course on the early management of severe sepsis. A prospective multicentre randomised study was performed enrolling resident physicians in emergency medicine from four hospitals in Asia. Participants were randomly assigned to a course that included didactic lectures followed by a skills workshop and simulated case scenario (lecture-first) or to a course that included a skills workshop and simulated case scenario followed by didactic lectures (simulation-first). A pre-test was given to the participants at the beginning of the course, post-test 1 was given after the didactic lectures or simulated case scenario depending on the study group assignment, then a final post-test 2 was given at the end of the course. Performance on the simulated case scenario was evaluated with a performance task checklist. 98 participants were enrolled in the study. Post-test 2 scores were significantly higher than pre-test scores in all participants (80.8 ± 12.0% vs 65.4 ± 12.2%, pdidactic lectures followed by simulation experience.

    Improving actionable stroke knowledge of a witness or bystander, which in some cases are children, may improve response to an acute stroke event. We used a quasiexperimental pre-test post-test design to evaluate actionable stroke knowledge of 210 children aged 9 to 10 years in response to a single, 15-minute exposure to a stroke education video game conducted in the school computer laboratory. After immediate post-test, we provided remote password-protected online video game access and encouraged children to play at their leisure from home. An unannounced delayed post-test occurred 7 weeks later. Two hundred ten children completed pretest, 205 completed immediate post-test, whereas 198 completed delayed post-test. One hundred fifty-six (74%) children had Internet access at home, and 41 (26%), mostly girls, played the video game remotely. There was significant improvement in stroke symptom composite scores, calling 911, and all individual stroke knowledge items, including a distractor across the testing sequence (PChildren who played the video game remotely demonstrated significant improvement in knowledge of 1 symptom (sudden imbalance) compared with children who did not (Pgames may represent novel means for improving and sustaining actionable stroke knowledge of children.

    This study aimed to assess the Parent-Adolescent Communication Toolkit, an online intervention designed to help improve parent communication with their adolescents. Participant preferences for two module delivery systems (sequential and unrestricted module access) were identified. Usability assessment of the PACT intervention was completed using pre-test and posttest comparisons. Usability data, including participant completion and satisfaction ratings were examined. Parents ( N  =   18) of adolescents were randomized to a sequential or unrestricted chapter access group. Parent participants completed pre-test measures, the PACT intervention and posttest measures. Participants provided feedback for the intervention to improve modules and provided usability ratings. Adolescent pre- and posttest ratings were evaluated. Usability ratings were high and parent feedback was positive. The sequential module access groups rated the intervention content higher and completed more content than the unrestricted chapter access group, indicating support for the sequential access design. Parent mean posttest communication scores were significantly higher ( p  Communication Toolkit has potential to improve parent-adolescent communication but further effectiveness assessment is required.

    Full Text Available Innovative teaching methods to address emerging practice needs are critical components of effective occupational therapy education. Experiential learning strategies can enhance skill development and translation of knowledge into OT clinical practice. In addition, skills such as coaching may provide important links to health promotion practices. Thirty-two occupational therapy students took part in an experiential project to connect occupational engagement and health for a community of older adults. A pretest/posttest design was used to evaluate program outcomes in student perceived abilities, and narrative reflection papers provided postexperience qualitative information. The students improved in all 10 areas of abilities selfassessment with mean total scores from pretest (M = 42 improving significantly at posttest (M = 58. Themes from reflection papers indicated a positive response to experiential learning and a desire for more opportunities to prepare for clinical practice, including the use of interprofessional training. The students improved in their abilities to use coaching and health promotion strategies through the use of experiential learning methods. Outcomes suggest that experiential learning opportunities are an effective way to enhance student competencies in coaching, improve readiness for wellness programming, and increase student confidence in application of skills in future clinical practice.

    The perception of rhythm cues plays an important role in recognizing spoken language, especially in adverse listening conditions. Indeed, this has been shown to hold true even when the rhythm cues themselves are dysrhythmic. This study investigates whether expertise in rhythm perception provides a processing advantage for perception (initial intelligibility) and learning (intelligibility improvement) of naturally dysrhythmic speech, dysarthria. Fifty young adults with typical hearing participated in 3 key tests, including a rhythm perception test, a receptive vocabulary test, and a speech perception and learning test, with standard pretest, familiarization, and posttest phases. Initial intelligibility scores were calculated as the proportion of correct pretest words, while intelligibility improvement scores were calculated by subtracting this proportion from the proportion of correct posttest words. Rhythm perception scores predicted intelligibility improvement scores but not initial intelligibility. On the other hand, receptive vocabulary scores predicted initial intelligibility scores but not intelligibility improvement. Expertise in rhythm perception appears to provide an advantage for processing dysrhythmic speech, but a familiarization experience is required for the advantage to be realized. Findings are discussed in relation to the role of rhythm in speech processing and shed light on processing models that consider the consequence of rhythm abnormalities in dysarthria.

    The current study evaluated adolescent patients' enjoyment of and knowledge gained from game-based learning compared with an interactive lecture format on the topic of mood disorders. It was hypothesized that game-based learning would be statistically more effective than a lecture in knowledge acquisition and satisfaction scores. A pre-post design was implemented in which a convenience sample of 160 adolescent patients were randomized to either a lecture (n = 80) or game-based (n = 80) group. Both groups completed a pretest/posttest and satisfaction survey. Results showed that both groups had significant improvement in knowledge from pretest compared to posttest. Game-based learning was statistically more effective than the interactive lecture in knowledge achievement and satisfaction scores. This finding supports the contention that game-based learning is an active technique that may be used with patient education.

    Because inguinal hernia repair is difficult for third-year students to comprehend, a 2-dimensional paper-cut was developed to teach the concepts of inguinal hernia in a time-effective manner before students' observation of herniorrhaphy in the operating room. Using Adobe Illustrator 5.5 for MacIntosh, a 2-dimensional inexpensively printed paper-cut was created to allow students to perform their own simulated hernia repair before observing surgery. The exercise was performed using a no.15 scalpel or an iris scissors and was evaluated by comparing 10-question pre-tests and post-tests. Seventy-five students performed the exercise, most completing it within 15 minutes. The mean pre-test score was 7.4/10 and the mean post-test score was 9.1/10. Students performing the paper-cut reported better understanding when observing actual herniorrhaphy. A 2-dimensional paper-cut ("surgical origami") may be a time-effective method to prepare students for the observation of hernia repair.

    The purpose of the study was to determine the effect of a support program on the resilience of female family caregivers of stroke patients. This is a randomized controlled trial. The sample consisted 70 female family caregivers (34 experimental, 36 control group). Data were collected three times (pretest-posttest, follow-up test). Data were collected using the demographical data form, the Family Index of Regenerativity and Adaptation-General. A significant difference was determined between the experimental and control group's follow-up test scores for relative and friend support, social support and family-coping coherence. A significant difference was determined between the experimental group's mean pretest, posttest and follow-up test scores in terms of family strain, relative and friend support, social support, family coping-coherence, family hardiness and family distress. These results suggest that the Support Program contributes to the improvement of the components of resilience of family caregivers of stroke patients. Copyright © 2016 Elsevier Inc.

    Full Text Available Previous research [S. J. Pollock et al., Phys. Rev. ST Phys. Educ. Res. 3, 1 (2007] showed that despite the use of interactive engagement techniques, the gap in performance between males and females on a conceptual learning survey persisted from pretest to post-test at the University of Colorado at Boulder. Such findings were counter to previously published work [M. Lorenzo et al., Am. J. Phys. 74, 118 (2006]. This study begins by identifying a variety of other gender differences. There is a small but significant difference in the course grades of males and females. Males and females have significantly different prior understandings of physics and mathematics. Females are less likely to take high school physics than males, although they are equally likely to take high school calculus. Males and females also differ in their incoming attitudes and beliefs about physics. This collection of background factors is analyzed to determine the extent to which each factor correlates with performance on a conceptual post-test and with gender. Binned by quintiles, we observe that males and females with similar pretest scores do not have significantly different post-test scores (p>0.2. The post-test data are then modeled using two regression models (multiple regression and logistic regression to estimate the gender gap in post-test scores after controlling for these important prior factors. These prior factors account for about 70% of the observed gender gap. The results indicate that the gender gap exists in interactive physics classes at our institution but is largely associated with differences in previous physics and math knowledge and incoming attitudes and beliefs.

    Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B). Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post-) were analyzed by two pediatric pulmonologists. Of the 66 professionals, 87.9% were females.

    Full Text Available The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called “SARMAD” to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD during 6 weeks and discussed. Then, students participated in a post-test. Students’ perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001; but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128. In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

    Faculty calibration studies for calculus detection use two different standards for examiner evaluation, yet the only therapeutic modality that can be used for nonsurgical periodontal treatment is scaling/root debridement or planing. In this study, a pretest-posttest design was used to assess the feasibility of faculty calibration for calculus detection using two accepted standards: that established by the Central Regional Dental Testing Service, Inc. (CRDTS; readily detectible calculus) and the gold standard for scaling/root debridement (root roughness). Four clinical dental hygiene faculty members out of five possible participants at Halifax Community College agreed to participate. The participants explored calculus on the 16 assigned teeth (64 surfaces) of four patients. Calculus detection scores were calculated before and after training. Kappa averages using CRDTS criteria were 0.561 at pretest and 0.631 at posttest. Kappa scores using the scaling/root debridement or planing standard were 0.152 at pretest and 0.271 at posttest. The scores indicated improvement from moderate (Kappa=0.41-0.60) to substantial agreement (Kappa=0.61-0.80) following training using the CRDTS standard. Although this result differed qualitatively and Kappas were significantly different from 0, the differences for pre- to post-Kappas for patient-rater dyads using CRDTS were not statistically significant (p=0.778). There was no difference (p=0.913) in Kappa scores pre- to post-training using the scaling/root debridement standard. Despite the small number of participants in this study, the results indicated that training to improve interrater reliability to substantial agreement was feasible using the CRDTS standard but not using the gold standard. The difference may have been due to greater difficulty in attaining agreement regarding root roughness. Future studies should include multiple training sessions with patients using the same standard for scaling/root debridement used for

    The Light-Water-Reactor (LWR) Aerosol Containment Experiments (LACE) are being performed in Richland, Washington, at the Hanford Engineering Development Laboratory (HEDL) under the leadership of an international project board and the Electric Power Research Institute. These tests have two objectives: (1) to investigate, at large scale, the inherent aerosol retention behavior in LWR containments under simulated severe accident conditions, and (2) to provide an experimental data base for validating aerosol behavior and thermal-hydraulic computer codes. Aerosol computer-code comparison activities are being coordinated at the Oak Ridge National Laboratory. For each of the six LACE tests, ''pretest'' calculations (for code-to-code comparisons) and ''posttest'' calculations (for code-to-test data comparisons) are being performed. The overall goals of the comparison effort are (1) to provide code users with experience in applying their codes to LWR accident-sequence conditions and (2) to evaluate and improve the code models

    Thousands of patients seek health services every day with complaints of pain. However, adequate pain assessment is still flawed, a fact that is partly related to gaps in professional learning on this topic. Innovative strategies such as the use of a virtual learning object mediated by persuasive technology in the learning of undergraduate nursing students can help to fill these gaps and to provide different ways of learning to learn. To evaluate the results in learning among undergraduate nursing students about assessment of acute pain in adults and newborns, before and after an online educational intervention. This is a quasi-experimental, non-equivalent study using pre-and post-testing. Federal University of Santa Catarina, Brazil. 75 undergraduate nursing students. Our study was conducted in three steps (pre-test, education intervention, post-test). Data were collected from November 2013 to February 2014. The educational intervention was performed using online access to virtual learning object about acute pain assessment, which students accessed on their mobile devices. A significant difference was seen in student learning (ptechnology and method applied. The use of persuasive technology such as small mobile devices as mediators of online educational interventions broadens learning spaces in an innovative, flexible, motivational, and promising manner.

    To cross-culturally adapt the Achilles tendon Total Rupture Score (ATRS) to Persian language and to preliminary evaluate the reliability and validity of a Persian ATRS. A cross-sectional and prospective cohort study was conducted to translate and cross-culturally adapt the ATRS to Persian language (ATRS-Persian) following steps described in guidelines. Thirty patients with total Achilles tendon rupture and 30 healthy subjects participated in this study. Psychometric properties of floor/ceiling effects (responsiveness), internal consistency reliability, test-retest reliability, standard error of measurement (SEM), smallest detectable change (SDC), construct validity, and discriminant validity were tested. Factor analysis was performed to determine the ATRS-Persian structure. There were no floor or ceiling effects that indicate the content and responsiveness of ATRS-Persian. Internal consistency was high (Cronbach's α 0.95). Item-total correlations exceeded acceptable standard of 0.3 for the all items (0.58-0.95). The test-retest reliability was excellent [(ICC)agreement 0.98]. SEM and SDC were 3.57 and 9.9, respectively. Construct validity was supported by a significant correlation between the ATRS-Persian total score and the Persian Foot and Ankle Outcome Score (PFAOS) total score and PFAOS subscales (r = 0.55-0.83). The ATRS-Persian significantly discriminated between patients and healthy subjects. Explanatory factor analysis revealed 1 component. The ATRS was cross-culturally adapted to Persian and demonstrated to be a reliable and valid instrument to measure functional outcomes in Persian patients with Achilles tendon rupture. II.

    Poor balance has been associated with increased injury risk among athletes. Neuromuscular-training programs have been advocated as a means of injury prevention, but little is known about the benefits of these programs on balance in high school athletes. To determine whether there are balance gains after participation in a neuromuscular-training program in high school athletes. Nonrandomized controlled trial. All data were collected at each participating high school before and after a 6-wk intervention or control period. 62 female high school basketball players recruited from the local high school community and assigned to a training (n = 37) or control (n = 25) group. Training-group subjects participated in a 6-wk neuromuscular-training program that included plyometric, functional-strengthening, balance, and stability-ball exercises. Data were collected for the Balance Error Scoring System (BESS) and Star Excursion Balance Test (SEBT) before and after the 6-wk intervention or control period. The authors found a significant decrease in total BESS errors in the trained group at the posttest compared with their pretest and the control group (P = .003). Trained subjects also scored significantly fewer BESS errors on the single-foam and tandem-foam conditions at the posttest than the control group and demonstrated improvements on the single-foam compared with their pretest (P = .033). The authors found improvements in reach in the lateral, anteromedial, medial, and posterior directions in the trained group at the posttest compared with the control group (P training program can increase the balance and proprioceptive capabilities of female high school basketball players and that clinical balance measures are sensitive to detect these differences.

    The realistic and practical environment that simulation provides is an extremely useful part of the teaching process. Simulation is widely used in health and nursing education today. This study aims to evaluate the effect of simulation-based teaching on the acquisition and retention of arrhythmia-related knowledge among nursing students. A randomized controlled design involving a pretest-posttest was used. Nursing students were allocated randomly either to the experimental group (n = 47), who attended simulation scenarios on cardiac arrhythmia, or to the control group (n = 44) who received a traditional lecture on the same topic. A paired t test showed that the mean knowledge score at the posttest was significantly higher than at the pretest for both groups. However, participants in the experimental group demonstrated significantly increased knowledge of cardiac arrhythmia in the first and the second posttest compared with those in the control group. Thus, simulation is superior and significantly improves students' arrhythmia knowledge. © The Author(s) 2014.

    1985-01-01

    Sixty-six community-residing elderly (mean age = 72.5) were categorized as depressed (mean = 11.3) or nondepressed (mean = 3.9) based on Beck Depression Inventory scores. After a pre-test battery measuring short-term memory and crystallized/fluid intelligence, the subjects responded to a word association task, disguised as a test of interpersonal empathy, under response dependent or response independent reinforcement conditions, or were assigned to a no treatment control. A post-test battery of alternate forms followed. Four of seven measures showed significant pre- to post-test declines in performance. For two of these four, response dependent reinforcement prevented otherwise significant declines. With pre-test differences statistically controlled, depression produced significant post-test deficits in three measures. Response dependent reinforcement eliminated this depression deficit in one measure. The results indicate that depression may exacerbate fatigue effects for the elderly and response dependent reinforcement may prevent fatigue-caused deficits in short-term memory.

    Burn prevention education for Amish children is warranted as there are unique risks associated with the Amish lifestyle. Specific educational opportunities are related to scalds, ignition of clothing, and ignition of highly flammable materials. A culturally sensitive burn prevention teaching tool, consisting of a magnetic storyboard, burn safety curriculum, and tests, was developed with the cooperation of one Old Order Amish community. The purpose of this study was to test the effectiveness of the tool in an Amish school. The teacher obtained parental permission and informed assent for the participation of the children. Pretesting was completed before the lessons began. The teacher told stories and arranged the magnets on the storyboard to show burn hazards involving lighters, stoves, kerosene heaters, gasoline-powered engines, and hot liquids used for canning, butchering, mopping, washing clothes, and making lye soap. The children were challenged to rearrange the pieces for a safer situation. Posttesting was performed 2 months after the pretest. Twenty-seven students (grades 1-8) participated. Tests were scored as a percentage of the 33 items answered correctly. The mean pretest score was 62 and the mean posttest score was 83. Statistical analysis using paired t-test demonstrated a highly significant improvement in test scores (P < .0001), with a power of more than 99%. This pilot study demonstrated that the burn prevention teaching tool was effective for improving knowledge in one classroom of Amish children. These results support expanded use and testing of this tool in other Amish schools.

    Gender differences on the Conceptual Survey in Electricity and Magnetism (CSEM) have been extensively studied. Ten semesters (N=1621) of CSEM data is presented showing male students outperform female students on the CSEM posttest by 5 % (p qualitative in-semester test questions by 3 % (p = . 004), but no significant difference between male and female students was found on quantitative test questions. Male students enter the class with superior prior preparation in the subject and score 4 % higher on the CSEM pretest (p questions correctly (N=822), male and female differences on the CSEM and qualitative test questions cease to be significant. This suggests no intrinsic gender bias exists in the CSEM itself and that gender differences are the result of prior preparation measured by CSEM pretest score. Gender differences between male and female students increase with pretest score. Regression analyses are presented to further explore interactions between preparation, gender, and achievement.

    Full Text Available Background: Our teaching hospitals have different grades of doctors with varied exposure to cardiac arrest settings and their resuscitation skills are often inadequate. Objectives: We investigated whether the grade of a doctor influenced acquisition of knowledge and skill during cardiopulmonary resuscitation (CPR training in Nigeria. Materials and Methods: Doctors who attended a two-day resuscitation training program between December 2007 and April 2009 were scored on their knowledge of Basic Life Support, Advanced Life Support, and performance at five skill stations. A pass mark was awarded for a post-test score ≥ 75% and a pass in all skill stations. Results: A total of 130 doctors were studied with a mean of 10.99 ± 6.51 years since medical qualification (range, 2-28 years. The mean pre-test score was 54.43 ± 16.10% (range 30.5-91.8% while the mean post-test score was 88.48 ± 6.8% (range, 54.6-94%, (P < 0.001. Mean post-test scores were not significantly different between grades. Mean scores for questions on Basic Life Support, defibrillator use, and drug therapy and in performance at skill stations were not significantly different between grades. A significant difference however existed in questions on cardiac arrest rhythms (P = 0.031. Sixty-five participants (50% passed the post-test at first attempt. Consultants, senior registrars, and registrars had pass rates of 59.2%, 53.6%, and 43.5% respectively (P = 0.336. After re-training at performance stations, 124 doctors (95.4% passed the test with no significant difference in overall pass in the various grades (P = 0.605. Conclusion : Grade of doctor did not affect the acquisition of knowledge and skill during resuscitation training.

    Full Text Available A web-based learning portal offering individualized learning was developed by utilizing rule-based knowledge representation and artificial intelligence techniques of expert systems in order to reduce the uncertainties of learning to minimum and to construct an intelligent tutoring system. This portal offers individualized learning content based on the individual’s level of cognitive knowledge. In order to determine the effects of the developed system on the student achievement, the system was tested in an 8-week-long study on the students of Software Engineering Department of Technology Faculty. The pretest-posttest control group experimental design was used in the study. The experimental group received education with Individualized Instruction Portal while the control group received education in traditional learning environment. Academic achievement test was used as the data collection tool. In order to test the research hypotheses, data obtained from the data collection tools were analysed in terms of frequency, percentages, and dependent-independent t-test with statistical software program. Based on the results, no significant differences were found between the groups in terms of the pretest. On the other hand, significant differences were found between experimental and control group in terms of the posttest. It was concluded that individualized learning portal had positive effect on the students’ learning when used in combination with traditional learning environment.

    Studies of physicians at all levels of training demonstrate significant deficiencies in cardiac auscultation skills. The best instructional methods to augment these skills are not known. This study was a randomized, controlled trial of 83 noncardiologist volunteers exposed to a 12-week lower cognitive load self-study group using MP3 players containing heart sound audio files compared to a group receiving a 1-time 1-hour higher cognitive load multimedia lecture using the same audio files. The primary outcome measure was change in 15-question posttest score at 4 and 12 weeks as compared to pretest on recognition of identical audio files introduced during training. In the self-study group, the association of total exposure and deliberate practice effort (estimated by standard deviation of files played/mean) to improvement in test score was measured as a secondary end point. Self-study group participants improved as compared to pretest by 4.42 ± 3.41 answers correct at 12 weeks (5.09-9.51 correct, p < .001), while those exposed to the multimedia lecture improved by an average of 1.13 ± 3.2 answers correct (4.48-5.61 correct, p = .03). In the self-study arm, improvement in the posttest was positively associated with both total exposure (β = 0.55, p < .001) and deliberate practice score (β = 0.31, p = .02). A lower cognitive load self-study of audio files improved recognition of cardiac sounds, as compared to multimedia lecture, and deliberate practice strategies improved study efficiency. More investigation is needed to assess transfer of learning to a wider range of cardiac sounds in both simulated and clinical environments. © 2014 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

    Full Text Available This paper examines how student effort, consistency, motivation, and marginal learning, influence student grades in an online course. We use data from eleven Microeconomics courses taught online for a total of 212 students. Our findings show that consistency, or less time variation, is a statistically significant explanatory variable, whereas effort, or total minutes spent online, is not. Other independent variables include GPA and the difference between a pre-test and a post-test. The GPA is used as a measure of motivation, and the difference between a post-test and pre-test as marginal learning. As expected, the level of motivation is found statistically significant at a 99% confidence level, and marginal learning is also significant at a 95% level.

    The aging of society is a global trend, and care of older adults with dementia is an urgent challenge. As dementia progresses, patients exhibit negative emotions, memory disorders, sleep disorders, and agitated behavior. Agitated behavior is one of the most difficult problems for family caregivers and healthcare providers to handle when caring for older adults with dementia. The aim of this study was to investigate the effectiveness of white noise in improving agitated behavior, mental status, and activities of daily living in older adults with dementia. An experimental research design was used to study elderly participants two times (pretest and posttest). Six dementia care centers in central and southern Taiwan were targeted to recruit participants. There were 63 participants: 28 were in the experimental group, and 35 were in the comparison group. Experimental group participants received 20 minutes of white noise consisting of ocean, rain, wind, and running water sounds between 4 and 5 P.M. daily over a period of 4 weeks. The comparison group received routine care. Questionnaires were completed, and observations of agitated behaviors were collected before and after the intervention. Agitated behavior in the experimental group improved significantly between pretest and posttest. Furthermore, posttest scores on the Mini-Mental Status Examination and Barthel Index were slightly better for this group than at pretest. However, the experimental group registered no significant difference in mental status or activities of daily living at posttest. For the comparison group, agitated behavior was unchanged between pretest and posttest. The results of this study support white noise as a simple, convenient, and noninvasive intervention that improves agitated behavior in older adults with dementia. These results may provide a reference for related healthcare providers, educators, and administrators who care for older adults with dementia.

    The aim of the present study was to determine the effect of imparting planned health education to climacteric women on their beliefs related to hot flushes and on their quality of life. The research was conducted using pretest and post-test semi-experimental models along with a control group. Of 450 women, 255 were randomly selected and invited to participate in the study. Five people did not agree to participate in the study. Three people were also excluded from the study because they did not complete training. The research sample was comprised of 247 climacteric women (121 women in the experimental group and 126 women in the control group) who were Life Questionnaire. Three educational sessions at 2-week intervals were given to the women in the experimental group. The research was supported with an educational booklet prepared by the researchers. Training was not given to the women in the control group. After the education of the experimental group (after about 6 months), women in both groups recompleted the data collection forms, and post-test data were collected. On all the subscales, the total of the Hot Flush Beliefs Scale, and the average post-test score, the women in the experimental group scored lower than the women in the control group (the average post-test total score in the experimental group was 26.22 ± 10.09 and in control group it was 52.25 ± 15.04; p Life Questionnaire for the women in the experimental group was lower than that for the women in the control group (p life of the women in the experimental group showed an upward trend, that of the women in the control group remained the same. It was found that planned health education about the climacteric period reduced women's negative beliefs about hot flushes and enhanced their quality of life.

    Full Text Available Objectives: To assess the baseline knowledge of fourth year student pharmacists on their ability to properly identify and categorize medication related problems (MRP during their Advanced Pharmacy Practice Experience (APPE in the ambulatory care setting, and to assess the efficacy of a written resource designed to educate and train users on identification and documentation of MRP's and used for this purpose with participating students on their ambulatory care APPE. Methods: A pretest consisting of ten multiple-choice questions was administered electronically to fourth year student pharmacists (N=18 at the start of their ambulatory care APPE. The test was designed to assess both the students' baseline knowledge regarding MRP's, and their ability to identify a wide variety of medication-related problems. Students then received a written copy of The Medication Therapy Intervention & Safety Documentation Program training manual and were asked to read it in its entirety in the first week of their APPE. Finally, students were given a posttest survey (identical to the pretest to complete to assess if their knowledge had increased from baseline. Results: The average score for the 18 students taking the baseline knowledge pre-test was 63.33%, indicating limited baseline knowledge regarding the identification and classification of MRP's. In assessing the effectiveness of the written training document, the overall posttest results compared to pretest results did not indicate improvement in students' knowledge or ability to properly identify and classify medication related problems (MRP after reviewing the training manual. The average scores declined from 63.33% on the pretest to 62.78% on the posttest, although this was not found to be statistically significant (p = 0.884. However, a statistically significant decline in students' knowledge occurred on one specific question, which tested their ability to classify MRP's (p = 0.029. Conclusions: Based on the

    The purpose of this research was to investigate the relationship between the learning style perceptual preferences of fourth grade urban students and the attainment of selected physical science concepts for three simple machines as taught using learning cycle methodology. The sample included all fourth grade children from one urban elementary school (N = 91). The research design followed a quasi-experimental format with a single group, equivalent teacher demonstration and student investigation materials, and identical learning cycle instructional treatment. All subjects completed the Understanding Simple Machines Test (USMT) prior to instructional treatment, and at the conclusion of treatment to measure student concept attainment related to the pendulum, the lever and fulcrum, and the inclined plane. USMT pre and post-test scores, California Achievement Test (CAT-5) percentile scores, and Learning Style Inventory (LSI) standard scores for four perceptual elements for each subject were held in a double blind until completion of the USMT post-test. The hypothesis tested in this study was: Learning style perceptual preferences of fourth grade students as measured by the Dunn, Dunn, and Price Learning Style Inventory (LSI) are significant predictors of success in the acquisition of physical science concepts taught through use of the learning cycle. Analysis of pre and post USMT scores, 18.18 and 30.20 respectively, yielded a significant mean gain of +12.02. A controlled stepwise regression was employed to identify significant predictors of success on the USMT post-test from among USMT pre-test, four CAT-5 percentile scores, and four LSI perceptual standard scores. The CAT -5 Total Math and Total Reading accounted for 64.06% of the variance in the USMT post-test score. The only perceptual element to act as a significant predictor was the Kinesthetic standard score, accounting for 1.72% of the variance. The study revealed that learning cycle instruction does not appear

    Asthma 1-2-3 is a newly-developed low-literacy multimedia education tool designed to promote asthma self-care concepts among African American adults. An expert panel (n = 10) informed content development for the tool. The video script and storyboard imagery were shown to 30 African Americans recruited from the American Lung Association, whose reactions and comments guided further revisions. The final version was pilot tested in three diverse community settings in Chicago to determine the efficacy of Asthma 1-2-3 at improving patient understanding of asthma and its symptoms. In all, 130 adults participated in the pilot test. Knowledge scores significantly improved from pretest to posttest following presentation of the developed tool for subjects across all literacy levels (Pretest: Mean = 4.2 [SD = 1.6]; Posttest: M = 6.8 [SD = 2.0], P < 0.001). Symptom pathophysiology concepts were the least understood. Individuals with low literacy had less total knowledge score gains compared to those with marginal and adequate literacy (1.8, 2.6, and 3.2 respectively; P = 0.002). The multimedia tool significantly improved understanding of asthma. Individuals with limited literacy may require additional instruction, repeated viewing, or added tangible cues (i.e. supplementary print materials) to support knowledge retention. In general, feedback from the target population was particularly helpful in the development of the tool and its initial evaluation, and should be considered as a necessary step in the creation of other patient education materials.

    This study implemented two pedagogical strategies, the Thinking Aloud Pair Problem Solving and Pólya’s Problem Solving, to support students’ learning of fractions. The participants were 51 students (ages 11-13) from two Year 7 classes in a government secondary school in Brunei Darussalam. A mixed method design was employed in the present study, with data collected from the pre- and post-tests, problem solving behaviour questionnaire and interviews. The study aimed to explore if there were differences in the students’ problem solving behaviour before and after the implementation of the problem solving strategies. Results from the Wilcoxon Signed Rank Test revealed a significant difference in the test results regarding student problem solving behaviour, z = -3.68, p = .000, with a higher mean score for the post-test (M = 95.5, SD = 13.8) than for the pre-test (M = 88.9, SD = 15.2). This implied that there was improvement in the students’ problem solving performance from the pre-test to the post-test. Results from the questionnaire showed that more than half of the students increased scores in all four stages of the Pólya’s problem solving strategy, which provided further evidence of the students’ improvement in problem solving.

    Mathues, Patricia Kelly

    Although the social constructivist theory proposed by Vygotsky states the value of discourse as a contribution to the ability of the learner to create meaning, student-led discussions have often been relegated to the language arts classroom. The standards created by the National Council of Teachers of English and the International Reading Association have long recognized that learners create meaning in a social context. The National Science Education Standards have also challenged science teachers to facilitate discourse. However, the science standards document provides no specific structure through which such discourse should be taught. This study investigated the effectiveness of a discussion strategy provided by Shoop and Wright for teaching and conducting student-centered discussions (SCD). Fifth graders in one school were randomly selected and randomly assigned to one of two science classes; 22 students in one class learned and applied the SCD strategies while a second class with 19 students learned the same science concepts from a teacher using traditional methods as described by Cazden. This study used a pretest-posttest design to test the hypothesis that participation in SCD's would effect a difference in fifth-graders' abilities to comprehend science concepts. Results of independent-samples t-tests showed that while there was no significant difference between the mean ability scores of the two groups of subjects as measured by a standardized mental abilities test, the mean pretest score of the traditional group was significantly higher than the SCD group's mean pretest score. ANCOVA procedures demonstrated that the SCD group's mean posttest score was significantly higher than the mean posttest score of the traditional group. Data analysis supported the rejection of the null hypothesis. The investigator concluded that the SCD methodology contributed to students' understanding of the science concepts. Results of this study challenge content area teachers to

    Mendonca, Flavio A. C.

    Analysis of bird strikes to aviation in the U.S. from 1990 to 2015 indicate that the successful mitigation efforts at airports, which must be sustained, have reduced incidents with damage and a negative effect-on-flight since 2000. However, such efforts have done little to reduce strikes outside the airport jurisdiction, such as occurred with US Airways Flight 1549 in 2009. There are basically three strategies to mitigate the risk of bird strikes: standards set by aviation authorities, technology, and actions by crewmembers. Pilots play an important role as stakeholders in the prevention of bird strikes, especially outside the airport environment. Thus, safety efforts require enhanced risk management and aeronautical decision-making training for flight crews. The purpose of this study was to determine if a safety training protocol could effectively enhance CFR Part 141 general aviation pilots' knowledge and skills to reduce the risk of bird strikes to aviation. Participants were recruited from the Purdue University professional flight program and from Purdue Aviation. The researcher of this study used a pretest posttest experimental design. Additionally, qualitative data were collected through open-ended questions in the pretest, posttest, and a follow-up survey questionnaire. The participants' pretest and posttest scores were analyzed using parametric and nonparametric tests. Results indicated a significant increase in the posttest scores of the experimental group. An investigation of qualitative data showed that the topic "safety management of bird hazards by pilots" is barely covered during the ground and flight training of pilots. Furthermore, qualitative data suggest a misperception of the safety culture tenets and a poor familiarity with the safety risk management process regarding bird hazards. Finally, the researcher presented recommendations for practice and future research.

    Ultrasound has been integrated into a gross anatomy course taught during the first year at an osteopathic medical school. A clinical ultrasound elective course was developed to continue ultrasound training during the second year of medical school. The purpose of this study was to evaluate the impact of this elective course on the understanding of normal anatomy by second-year students. An anatomy exam was administered to students enrolled in the clinical ultrasound elective course before the start of the course and after its conclusion. Wilcoxon signed ranks tests were used to determine whether exam scores changed from the pre-test to the post-test. Scores from two classes of second-year students were analyzed. Students who took the elective course showed significant improvement in the overall anatomy exam score between the pre-test and post-test (P students with an important review of key anatomical concepts while preparing them for board exams. Our results suggested that more emphasis should be placed on head and neck ultrasound to improve student performance in those areas. Musculoskeletal, abdominal, and heart ultrasound labs were more successful for retaining relevant anatomical information. © 2014 Wiley Periodicals, Inc.

    Novel methods for teaching are needed to enhance the efficiency of academic anesthesia departments as well as provide approaches to learning that are aligned with current trends and advances in technology. A video was produced that taught the key elements of anesthesia machine checkout and room set up. Novice learners were randomly assigned to receive either the new video format or traditional lecture-based format for this topic during their regularly scheduled lecture series. Primary outcome was the difference in written examination score before and after teaching between the two groups. Secondary outcome was the satisfaction score of the trainees in the two groups. Forty-two students assigned to the video group and 36 students assigned to the lecture group completed the study. Students in each group similar interest in anesthesia, pre-test scores, post-test scores, and final exam scores. The median posttest to pretest difference was greater in the video groups (3.5 (3.0-5.0) vs 2.5 (2.0-3.0), for video and lecture groups respectively, p 0.002). Despite improved test scores, students reported higher satisfaction the traditional, lecture-based format (22.0 (18.0-24.0) vs 24.0 (20.0-28.0), for video and lecture groups respectively, p students in the video-based teaching group, however students rated traditional, live lectures higher than newer video-based teaching.

    The Mini-Mental State Examination (MMSE) is considered a useful supplementary method to diagnose dementia and evaluate the severity of cognitive disturbance. However, the region of the cerebrum that correlates with the MMSE score is not clear. Recently, a new method was developed to analyze regional cerebral blood flow (rCBF) using a Z score imaging system (eZIS). This system shows changes of rCBF when compared with a normal database. In addition, a three-dimensional stereotaxic region of interest (ROI) template (3DSRT), fully automated ROI analysis software was developed. The objective of this study was to investigate the correlation between rCBF changes and total MMSE score using these new methods. The association between total MMSE score and rCBF changes was investigated in 24 patients (mean age±standard deviation (SD) 71.5±9.2 years; 6 men and 18 women) with memory impairment using eZIS and 3DSRT. Step-wise multiple regression analysis was used for multivariate analysis, with the total MMSE score as the dependent variable and rCBF change in 24 areas as the independent variable. Total MMSE score was significantly correlated only with the reduction of left hippocampal perfusion but not with right (P<0.01). Total MMSE score is an important indicator of left hippocampal function. (author)

    To describe the sensitivity and specificity of Coma Recovery Scale-Revised (CRS-R) total scores in detecting conscious awareness. Data were retrospectively extracted from the medical records of patients enrolled in a specialized disorders of consciousness (DOC) program. Sensitivity and specificity analyses were completed using CRS-R-derived diagnoses of minimally conscious state (MCS) or emerged from minimally conscious state (EMCS) as the reference standard for conscious awareness and the total CRS-R score as the test criterion. A receiver operating characteristic curve was constructed to demonstrate the optimal CRS-R total cutoff score for maximizing sensitivity and specificity. Specialized DOC program. Patients enrolled in the DOC program (N=252, 157 men; mean age, 49y; mean time from injury, 48d; traumatic etiology, n=127; nontraumatic etiology, n=125; diagnosis of coma or vegetative state, n=70; diagnosis of MCS or EMCS, n=182). Not applicable. Sensitivity and specificity of CRS-R total scores in detecting conscious awareness. A CRS-R total score of 10 or higher yielded a sensitivity of .78 for correct identification of patients in MCS or EMCS, and a specificity of 1.00 for correct identification of patients who did not meet criteria for either of these diagnoses (ie, were diagnosed with vegetative state or coma). The area under the curve in the receiver operating characteristic curve analysis is .98. A total CRS-R score of 10 or higher provides strong evidence of conscious awareness but resulted in a false-negative diagnostic error in 22% of patients who demonstrated conscious awareness based on CRS-R diagnostic criteria. A cutoff score of 8 provides the best balance between sensitivity and specificity, accurately classifying 93% of cases. The optimal total score cutoff will vary depending on the user's objective.

    Several models and theories have been proposed to help registered dietitians (RD) counsel and communicate nutrition information to patients. However, there is little time for students or interns to observe and/or participate in counseling sessions. Computer-assisted instruction (CAI) can be used to give students more opportunity to observe the various methods and theories of counseling. This study used CAI simulations of RD-client communications to examine whether students who worked through the CAI modules would choose more appropriate counseling methods. Modules were created based on information from experienced RD. They contained videos of RD-patient interactions and demonstrated helpful and less helpful methods of communication. Students in didactic programs in dietetics accessed the modules via the Internet. The intervention group of students received a pretest module, two tutorial modules, and a posttest module. The control group only received the pretest and posttest modules. Data were collected during three semesters in 2006 and 2007. Two sample t tests were used to compare pretest and posttest scores. The influence of other factors was measured using factorial analysis of variance. Statistical significance was set at Pcommunication and counseling methods for dietetics students. 2010 American Dietetic Association. Published by Elsevier Inc. All rights reserved.

    Full Text Available The current study is an attempt to investigate the explicit or the implicit instruction of metadiscourse markers and the writing skill improvement. The participants of the study (N = 90 were female Iranian students at Kish Institute of Science and Technology. Two experimental groups were defined in this study: experimental group “A” which received the explicit instruction of metadiscourse markers and experimental group “B” which were taught implicitly based on Hyland’s (2005 classification of metadiscourse markers. Two instruments were employed in the study: a pretest and a posttest. To elicit the pertinent data, the participants were given a pretest of writing ability to investigate if the learners had knowledge regarding the correct application of ‎metadiscourse markers in their writing. After 8-session treatment, a posttest was administered to compare the participants’ performance in use of matediscourse markers. The findings of the present study indicated that there was a significant difference in the participants’ pretest and posttest writing scores with regard to the application of metadiscourse markers. The findings revealed that metadiscourse instruction had a positive effect on the learners’ writing. In addition, the results showed that both the explicit and the implicit instruction of metadiscourse markers significantly improved participants’ writing ability.

    Background Nurses are usually the first to identify the need for and initiate cardiopulmonary resuscitation (CPR) on patients with cardiopulmonary arrest in the hospital setting. Cardiopulmonary resuscitation has been shown to reduce in-hospital deaths when received from adequately trained health care professionals. Aim We aimed to investigate nurses’ retention of CPR knowledge and skills at district hospitals in Botswana. Methods A quantitative, quasi-experimental study was conducted at three hospitals in Botswana. A pre-test, intervention, post-test, and a re-test after 6 months were utilised to determine the retention of CPR knowledge and skills. Non-probability, convenience sampling technique was used to select 154 nurses. The sequences of the test were consistent with the American Heart Association’s 2010 basic life support (BLS) guidelines for health care providers. Data were analysed to compare performance over time. Results This study showed markedly deficient CPR knowledge and skills among registered nurses in the three district hospitals. The pre-test knowledge average score (48%) indicated that the nurses did not know the majority of the BLS steps. Only 85 nurses participated in the re-evaluation test at 6 months. While a 26.4% increase was observed in the immediate post-test score compared with the pre-test, the performance of the available participants dropped by 14.5% in the re-test 6 months after the post-test. Conclusion Poor CPR knowledge and skills among registered nurses may impede the survival and management of cardiac arrest victims. Employers and nursing professional bodies in Botswana should encourage and monitor regular CPR refresher courses. PMID:29781687

While a 26.4% increase was observed in the immediate post-test score compared with the pre-test, the performance of the available participants dropped by 14.5% in the re-test 6 months after the post-test.  Poor CPR knowledge and skills among registered nurses may impede the survival and management of cardiac arrest victims. Employers and nursing professional bodies in Botswana should encourage and monitor regular CPR refresher courses.

    Background Analysis of variance (ANOVA), change-score analysis (CSA) and analysis of covariance (ANCOVA) respond differently to baseline imbalance in randomized controlled trials. However, no empirical studies appear to have quantified the differential bias and precision of estimates derived from these methods of analysis, and their relative statistical power, in relation to combinations of levels of key trial characteristics. This simulation study therefore examined the relative bias, precision and statistical power of these three analyses using simulated trial data. Methods 126 hypothetical trial scenarios were evaluated (126 000 datasets), each with continuous data simulated by using a combination of levels of: treatment effect; pretest-posttest correlation; direction and magnitude of baseline imbalance. The bias, precision and power of each method of analysis were calculated for each scenario. Results Compared to the unbiased estimates produced by ANCOVA, both ANOVA and CSA are subject to bias, in relation to pretest-posttest correlation and the direction of baseline imbalance. Additionally, ANOVA and CSA are less precise than ANCOVA, especially when pretest-posttest correlation ≥ 0.3. When groups are balanced at baseline, ANCOVA is at least as powerful as the other analyses. Apparently greater power of ANOVA and CSA at certain imbalances is achieved in respect of a biased treatment effect. Conclusions Across a range of correlations between pre- and post-treatment scores and at varying levels and direction of baseline imbalance, ANCOVA remains the optimum statistical method for the analysis of continuous outcomes in RCTs, in terms of bias, precision and statistical power.

    Relationships between sixth grade students' moon journaling and students' spatial-scientific reasoning after implementation of an Earth/Space unit were examined. Teachers used the project-based Realistic Explorations in Astronomical Learning curriculum. We used a regression model to analyze the relationship between the students' Lunar Phases Concept Inventory (LPCI) post-test score variables and several predictors, including moon journal score, number of moon journal entries, student gender, teacher experience, and pre-test score. The model shows that students who performed better on moon journals, both in terms of overall score and number of entries, tended to score higher on the LPCI. For every 1 point increase in the overall moon journal score, participants scored 0.18 points (out of 20) or nearly 1% point higher on the LPCI post-test when holding constant the effects of the other two predictors. Similarly, students who increased their scores by 1 point in the overall moon journal score scored approximately 1% higher in the Periodic Patterns (PP) and Geometric Spatial Visualization (GSV) domains of the LPCI. Also, student gender and teacher experience were shown to be significant predictors of post-GSV scores on the LPCI in addition to the pre-test scores, overall moon journal score, and number of entries that were also significant predictors on the LPCI overall score and the PP domain. This study is unique in the purposeful link created between student moon observations and spatial skills. The use of moon journals distinguishes this study further by fostering scientific observation along with skills from across science, technology, engineering, and mathematics disciplines.

    Clinically depressed persons suffer from impaired mood and distortion of cognition. This study assessed changes in depression severity and perceived attentional capacity of clinically depressed adults (N=18) during a 12-week therapeutic horticulture program. The Beck Depression Inventory (BDI) and Attentional Function Index (AFI) were administered at baseline, twice during (4 and 8 weeks), and immediately after the intervention (12 weeks), and at a 3-month follow-up. Experiences of being away and fascination related to the intervention were measured at 4, 8, and 12 weeks. The mean BDI score declined 9.7 points from pretest (27.3) to posttest (p or =6) for 72% of the cases. The mean AFI score increased 10.2 points from pretest (68.8) to posttest (p = .06). The greatest change in BDI and AFI scores occurred in the initial weeks of the intervention. The reduction in BDI scores remained significant and clinically relevant at the 3-month follow-up (N=16). The decline in depression severity during the intervention correlated strongly with the degree to which the participants found that it captured their attention. Therapeutic horticulture may decrease depression severity and improve perceived attentional capacity by engaging effortless attention and interrupting rumination.

    This prospective study compares the use of interactive multimedia eBooks (IME) with traditional PowerPoint (TPP) for teaching cell morphology of blood and bone marrow. Fifty-one interns from three Taiwan medical schools training by a single teacher in the pediatric hematology department of Kaohsiung Chang Gung Memorial Hospital, Taiwan, participated in this study. 25 interns were allocated for training with a traditional PowerPoint atlas and 26 interns for training with an interactive multimedia eBook atlas. Learning outcomes were examined by pre-test and post-test using the CellQuiz of CellAtlas App. Attitudes and perceptions were collected by survey questions regarding interest, motivation and effectiveness. There was no difference in the pre-test scores between TPP and IME groups (mean score 27.0 versus 27.9, p = 0.807). However, the interns in the interactive multimedia eBook group achieved significantly better scores in the post-test than the ones in the PowerPoint group (mean score 103.2 versus 70.6; p < 0.001). Overall results of interest, motivation and effectiveness were strongly positive in the multimedia eBook group. Our data supports that interactive multimedia eBooks are more effective than PowerPoint to facilitate learning of cell morphology of blood and bone marrow.

    The use of standardized patients is not very common in psychiatric nursing education and there has been no study conducted in Turkey. This study evaluated the impact of using standardized patients in psychiatric cases on the levels of motivation and perceived learning of the nursing students. This manuscript addressed the quantitative aspect of a doctoral thesis study in which both quantitative and qualitative methods were used. A pre-test and post-test were employed in the quantitative analysis in a randomized and controlled study design. The motivation scores, and interim and post-test scores for perceived learning were higher in the experimental group compared to pre-test scores and the scores of the control group. The students in the experimental group reported that they felt more competent about practical training in clinical psychiatry, as well as in performing interviews with patients having mental problems, and reported less anxiety about performing an interview when compared to students in the control group. It is considered that the inclusion of standardized patient methodology in the nursing education curriculum in order to improve the knowledge level and skills of students would be beneficial in the training of mental health nurses.

    Full Text Available The goal of this study was to verify whether association of aromatherapy with essential oils of Satureja brevicalyx or Satureja boliviana and mindfulness meditation can reduce anxiety levels in humans. A randomized experimental trial was carried out with 108 participants who were divided into 6 groups, comprising a waiting list control group and five experimental groups. Aromatherapy was carried out by inhalation of essential oils while mindfulness intervention program was focused on “flow meditation”. The anxiety index was evaluated by State-Trait Anxiety Inventory (STAI. Measures were taken two times: pretest and posttest. State and Trait anxiety scores showed a decrease in posttest study phase in comparison with pretest in all experimental groups (p < 0.005, especially in those where aromatherapy and mindfulness meditation were used together. All Cohen's d scores were over to 1 that means a large size effect in anxiety variable. Percentages of change showed reductions of anxiety variable ranging between 20% and 47%. All treatments used isolated or associated, may be considered alternative treatment options for anxiety.

    The purpose of this research was to determine if there were differences in academic performance between students who participated in traditional versus collaborative problem-based learning (PBL) instructional design approaches to physics curricula. This study utilized a quantitative quasi-experimental design methodology to determine the significance of differences in pre- and posttest introductory physics exam performance between students who participated in traditional (i.e., control group) versus collaborative problem solving (PBL) instructional design (i.e., experimental group) approaches to physics curricula over a college semester in 2008. There were 42 student participants (N = 42) enrolled in an introductory physics course at the research site in the Spring 2008 semester who agreed to participate in this study after reading and signing informed consent documents. A total of 22 participants were assigned to the experimental group (n = 22) who participated in a PBL based teaching methodology along with traditional lecture methods. The other 20 students were assigned to the control group (n = 20) who participated in the traditional lecture teaching methodology. Both the courses were taught by experienced professors who have qualifications at the doctoral level. The results indicated statistically significant differences (p traditional (i.e., lower physics posttest scores and lower differences between pre- and posttest scores) versus collaborative (i.e., higher physics posttest scores, and higher differences between pre- and posttest scores) instructional design approaches to physics curricula. Despite some slight differences in control group and experimental group demographic characteristics (gender, ethnicity, and age) there were statistically significant (p = .04) differences between female average academic improvement which was much higher than male average academic improvement (˜63%) in the control group which may indicate that traditional teaching methods

    Physicians require extensive training to achieve proficiency in mechanical ventilator (MV) management of the critically ill patients. Guided self-directed learning (GSDL) is usually the method used to learn. However, it is unclear if this is the most proficient approach to teaching mechanical ventilation to critical care fellows. We, therefore, investigated whether critical care fellows achieve higher scores on standardized testing and report higher satisfaction after participating in a hands-on tutorial combined with GSDL compared to self-directed learning alone. First-year Pulmonary and Critical Care Medicine (PCCM) fellows ( n =6) and Critical Care Internal Medicine (CCIM) ( n =8) fellows participated. Satisfaction was assessed using the Likert scale. MV knowledge assessment was performed by administering a standardized 25-question multiple choice pre- and posttest. For 2 weeks the CCIM fellows were exposed to GSDL, while the PCCM fellows received hands-on tutoring combined with GSDL. Ninety-three percentage (6 PCCM and 7 CCIM fellows, total of 13 fellows) completed all evaluations and were included in the final analysis. CCIM and PCCM fellows scored similarly in the pretest (64% vs. 52%, p =0.13). Following interventions, the posttest scores increased in both groups. However, no significant difference was observed based on the interventions (74% vs. 77%, p =0.39). The absolute improvement with the hands-on-tutoring and GSDL group was higher than GSDL alone (25% vs. 10%, p =0.07). Improved satisfaction scores were noted with hands-on tutoring. Hands-on tutoring combined with GSDL and GSDL alone were both associated with an improvement in posttest scores. Absolute improvement in test and satisfaction scores both trended higher in the hands-on tutorial group combined with GSDL group.

    Dental hygiene students must embody effective critical thinking skills in order to provide evidence-based comprehensive patient care. The problem addressed in this study it was not known if and to what extent concept mapping and reflective journaling activities embedded in a curriculum over a 4-week period, impacted the critical thinking skills of 22 first and second-year dental hygiene students attending a community college in the Midwest. The overarching research questions were: what is the effect of concept mapping, and what is the effect of reflective journaling on the level of critical thinking skills of first and second year dental hygiene students? This quantitative study employed a quasi-experimental, pretest-posttest design. Analysis of Covariance (ANCOVA) assessed students' mean scores of critical thinking on the California Critical Thinking Skills Test (CCTST) pretest and posttest for the concept mapping and reflective journaling treatment groups. The results of the study found an increase in CCTST posttest scores with the use of both concept mapping and reflective journaling. However, the increase in scores was not found to be statistically significant. Hence, this study identified concept mapping using Ausubel's assimilation theory and reflective journaling incorporating Johns's revision of Carper's patterns of knowing as potential instructional strategies and theoretical models to enhance undergraduate students' critical thinking skills. More research is required in this area to draw further conclusions. Keywords: Critical thinking, critical thinking development, critical thinking skills, instructional strategies, concept mapping, reflective journaling, dental hygiene, college students.

    2016-03-01

    Several authors have tested the accuracy of the Total Body Score (TBS) method for quantifying decomposition, but none have examined the reliability of the method as a scoring system by testing interobserver error rates. Sixteen participants used the TBS system to score 59 observation packets including photographs and written descriptions of 13 human cadavers in different stages of decomposition (postmortem interval: 2-186 days). Data analysis used a two-way random model intraclass correlation in SPSS (v. 17.0). The TBS method showed "almost perfect" agreement between observers, with average absolute correlation coefficients of 0.990 and average consistency correlation coefficients of 0.991. While the TBS method may have sources of error, scoring reliability is not one of them. Individual component scores were examined, and the influences of education and experience levels were investigated. Overall, the trunk component scores were the least concordant. Suggestions are made to improve the reliability of the TBS method. © 2016 American Academy of Forensic Sciences.

In the discordant groups, the pretest averaged 51.9%, the immediate posttest was 67.1% and the delayed by 68.8%. In the concordant groups, the immediate post-test scores improved by 21.4%, compared with 15.2% in the discordant groups (p = 0.655. In the delayed post-test the concordant scores improved by 10.5% and discordant scores by 16.9 percent (p=0.609. Sixty-two percent of students surveyed preferred the format of online videos with in-class case discussion to a traditional lecture format. Conclusion Immediate post-tests and delayed post-tests improved but priming was not demonstrated to be a statistically superior educational method in this study. Medical student completion of the preparatory materials for the EM rotation session increased when the students were EM-bound. Participation rates were not significantly different when given at two weeks versus three days.

    According to the 36-Item Short Form Health Survey questionnaire developers, a global measure of health-related quality of life such as the "SF-36 Total/Global/Overall Score" cannot be generated from the questionnaire. However, studies keep on reporting such measure. This study aimed to evaluate the frequency and to describe some characteristics of articles reporting the SF-36 Total/Global/Overall Score in the scientific literature. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was adapted to a scoping review. We performed searches in PubMed, Web of Science, SCOPUS, BVS, and Cochrane Library databases for articles using such scores. We found 172 articles published between 1997 and 2015; 110 (64.0%) of them were published from 2010 onwards; 30.0% appeared in journals with Impact Factor 3.00 or greater. Overall, 129 (75.0%) out of the 172 studies did not specify the method for calculating the "SF-36 Total Score"; 13 studies did not specify their methods but referred to the SF-36 developers' studies or others; and 30 articles used different strategies for calculating such score, the most frequent being arithmetic averaging of the eight SF-36 domains scores. We concluded that the "SF-36 Total/Global/Overall Score" has been increasingly reported in the scientific literature. Researchers should be aware of this procedure and of its possible impacts upon human health.

    Full Text Available This study investigates the effect of homogeneous and heterogeneous peer interaction on the development of Iranian EFL learners’ writing skill. Sixty female students of TEFL participated in the study. The participants were divided into two groups based on their English proficiency test scores. The homogeneous group consisted of 14 participants paired with partners with similar English proficiency test scores, while the heterogeneous group consisted of 16 participants who were paired with partners who had higher test scores. The pairs had interaction and peer collaboration before carrying out three types of writing tasks. The Repeated Measures ANOVA was used to compare the student writers’ pretest writing scores with their three post-test scores. The results showed that both groups, very similarly, had significantly higher post-test scores in all three writing tasks. The findings are explained based on the sociocultural theory and Vygotsky’s notion of the zone of proximal development (ZPD. The study offers several important pedagogical implications and suggestions for further research.

    The main objective of the study was to enhance knowledge construction activities on its design particularly the objectives, support materials, student activities and assessment tools. Activities from the 2nd Quarter of Science Learners Material were the basis in the adaptation of activities. The adapted activities were evaluated by the In-service Science teachers and undergone modification by the researchers based on the teacher's comments and suggestions. It was then evaluated, revised, and validated, tried-out using the 21st CLD Rubric. Subjects of the study were 110 students from Grade 7-B, Grade 7-D, Grade 7-F in Geronima Cabrera National High School, Kolambugan, Lanao del Norte during the academic year 2016-2017, the study to determine their learning capabilities investigated by the use of Knowledge Construction Activities in the 21st Century Classroom, to investigate how the lessons were understood and appreciated by students, to stimulate interpretation, analysis, synthesizing, or evaluating ideas and develop critical thinking. Both quantitative and qualitative data were obtained from the students' scores in three activities. Results showed that there was a significant difference between the pretest and posttest scores of students. Mean scores between the pretest and posttest showed a mean difference of 3.35, thus the null hypothesis was rejected. It could be concluded with sufficient evidence to show that the students had basically low prior knowledge about the topic ecosystem. A significant difference was seen in the pretest and posttest, scores of the activities and Ecosystem model results after the implementation phase that a knowledge construction type of activity was better than the traditional one for it promoted meaningful learning and active engagement of students. Based on the results, it was clear that the use of knowledge construction activities had an effect on student's achievement in comparison to traditional teaching method. Thus, it was

    Werth, Arman Karl

    Cooperative learning has been one of the most widely used instructional practices around the world since the early 1980's. Small learning groups have been in existence since the beginning of the human race. These groups have grown in their variance and complexity overtime. Classrooms are getting more diverse every year and instructors need a way to take advantage of this diversity to improve learning. The purpose of this study was to see if heterogeneous cooperative learning groups based on student achievement can be used as a differentiated instructional strategy to increase students' ability to demonstrate knowledge of science concepts and ability to do engineering design. This study includes two different groups made up of two different middle school science classrooms of 25-30 students. These students were given an engineering design problem to solve within cooperative learning groups. One class was put into heterogeneous cooperative learning groups based on student's pre-test scores. The other class was grouped based on random assignment. The study measured the difference between each class's pre-post gains, student's responses to a group interaction form and interview questions addressing their perceptions of the makeup of their groups. The findings of the study were that there was no significant difference between learning gains for the treatment and comparison groups. There was a significant difference between the treatment and comparison groups in student perceptions of their group's ability to stay on task and manage their time efficiently. Both the comparison and treatment groups had a positive perception of the composition of their cooperative learning groups.

    This study examined dynamic assessment as a lessbiased evaluation procedure for assessing the languagelearning ability of Native American children. Twenty-three Arapahoe/Shoshone kindergartners were identified as stronger (n = 15) or weaker (n = 8) language learners through teacher report and examiner classroom observation. Through a test-teach-test protocol, participants were briefly taught the principles of categorization. Participant responses to learning were measured in terms of an index of modifiability and post-test categorization scores. The modifiability index, determined during the teaching phase, was a combined score reflecting the child's learning strategies, such as ability to attend, plan, and self-regulate, and the child's responses to the learning situation. Post-test scores consisted of performance on expressive and receptive subtests from a standardized categorization test after partialling out pretest score differences. Effect sizes and confidence intervals were also determined. Group and individual results indicated that modifiability and post-test scores were significantly greater for stronger than for weaker language learners. The response to modifiability components was a better discriminator than was the learner strategies components. These results provide support for the further development of dynamic assessment as a valid measure of language learning ability in minority children.

    Our objective is to characterize and assess upper division and graduate student thinking by developing and testing an assessment tool for a physical hydrology class. The class' learning goals are: (1) Quantitative process-based understanding of hydrologic processes, (2) Experience with different methods in hydrology, (3) Learning, problem solving, communication skills. These goals were translated into two measurable tasks asked of students in a questionnaire: (1) Describe the significant processes in the hydrological cycle and (2) Describe laws governing these processes. A third question below assessed the students' ability to apply their knowledge: You have been hired as a consultant by __ to (1) assess how urbanization and the current drought have affected a local spring and (2) predict what the effects will be in the future if the drought continues. What information would you need to gather? What measurements would you make? What analyses would you perform? Student and expert responses to the questions were then used to develop a rubric to score responses. Using the rubric, 3 researchers independently blind-coded the full set of pre and post artifacts, resulting in 89% inter-rater agreement on the pre-tests and 83% agreement on the post-tests. We present student scores to illustrate the use of the rubric and to characterize student thinking prior to and following a traditional course. Most students interpreted Q1 in terms of physical processes affecting the water cycle, the primary organizing framework for hydrology, as intended. On the pre-test, one student scored 0, indicating no response, on this question. Twenty students scored 1, indicating rudimentary understanding, 2 students scored a 2, indicating a basic understanding, and no student scored a 3. Student scores on this question improved on the post-test. On the 22 post-tests that were blind scored, 11 students demonstrated some recognition of concepts, 9 students showed a basic understanding, and 2

    A retrospective multi-centre study was carried out in order to compare outcomes between cemented and uncemented total hip arthoplasties (THA). A quantitative orthopaedic outcome assessment scoring system was devised in order to relate functional outcome to a numerical score, to allow comparison between treatments and amongst centres. The system combined a radiographic score and a clinical score. Lower scores reflect better outcomes than higher scores. Consecutive cases of THA were included from two specialist practices between July 2002 and December 2005. The study included 46 THA patients (22 uncemented THA followed for 8.3 +/- 4.7M and 24 cemented THA for 26.0 +/- 15.7M) with a mean age of 4.4 +/- 3.3 years at surgery. Multi-variable linear and logistical regression analyses were performed with adjustments for age at surgery, surgeon, follow-up time, uni- versus bilateral disease, gender and body weight. The differences between treatment groups in terms of functional scores or total scores were not significant (p > 0.05). Radiographic scores were different between treatment groups. However, these scores were usually assessed within two months of surgery and proved unreliable predictors of functional outcome (p > 0.05). The findings reflect relatively short-term follow-up, especially for the uncemented group, and do not include clinician-derived measures, such as goniometry and thigh circumference. Longer-term follow-up for the radiographic assessments is essential. A prospective study including the clinician-derived outcomes needs to be performed in order to validate the outcome instrument in its modified form.

    We assessed the usefulness of gated stress/rest 99mTc-tetrofosmin myocardial perfusion single photon emission computed tomography (SPECT) to predict ischemic cardiac events in Japanese patients with various estimated pretest probabilities of coronary artery disease (CAD). Of the 4031 consecutively registered patients for a J-ACCESS (Japanese Assessment of Cardiac Events and Survival Study by Quantitative Gated SPECT) study, 1904 patients without prior cardiac events were selected. Gated stress/rest myocardial perfusion SPECT was performed and segmental perfusion scores and quantitative gated SPECT results were derived. The pretest probability for having CAD was estimated using the American College of Cardiology/American Heart Association/American College of Physicians- American Society of Internal Medicine guideline data for the management of patients with chronic stable angina, which includes age, gender, and type of chest discomfort. The patients were followed up for three years. During the three-year follow-up period, 96 developed ischemic cardiac events: 17 cardiac deaths, 8 nonfatal myocardial infarction, and 71 clinically driven revascularization. The summed stress score (SSS) was the most powerful independent predictor of all ischemic cardiac events (hazard ratio 1.077, confidence interval (CI) 1.045-1.110). Abnormal SSS (>3) was associated with a significantly higher cardiac event rate in patients with an intermediate to high pretest probability of CAD. Normal SSS (≤3) was associated with a low event rate in patients with any pretest probability of CAD. Myocardial perfusion SPECT is useful for further risk-stratification of patients with suspected CAD. The abnormal scan result (SSS>3) is discriminative for subsequent cardiac events only in the groups with an intermediate to high pretest probability of CAD. The salient result is that normal scan results portend a benign prognosis independent from the pretest probability of CAD. (author)

    Manual perturbation training improves dynamic knee stability and functional performance after anterior cruciate ligament rupture (ACL-rupture). However, it is limited to static standing position and does not allow time-specific perturbations at different phase of functional activities. The purpose of this study was to investigate whether administering mechanical perturbation training including compliant surface provides effects similar to manual perturbation training on knee functional measures after an acute ACL-rupture. Sixteen level I/II athletes with ACL-ruptures participated in this preliminary study. Eight patients received mechanical (Mechanical) and eight subjects received manual perturbation training (Manual). All patients completed a functional testing (isometric quadriceps strength, single-legged hop tests) and patient-reported measures (Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS), Global Rating Score (GRS), International Knee Documentation Committee 2000 (IKDC 2000) at pre- and post-training. 2 × 2 ANOVA was used for data analysis. No significant group-by-time interactions were found for all measures (p > 0.18). Main effects of time were found for single hop (Pre-testing: 85.14% ± 21.07; Post-testing: 92.49% ± 17.55), triple hop (Pre-testing: 84.64% ± 14.17; Post-testing: 96.64% ± 11.14), KOS-ADLS (Pre-testing: 81.13% ± 11.12; Post-testing: 88.63% ± 12.63), GRS (Pre-testing: 68.63% ± 15.73; Post-testing: 78.81% ± 13.85), and IKDC 2000 (Pre-testing: 66.66% ± 9.85; Post-testing: 76.05% ± 14.62) (p training using compliant surfaces induce effects similar to manual perturbation training on knee functional performance after acute ACL-rupture.

    Purpose: Radiation oncologists are faced with the challenge of irradiating tumors to a curative dose while limiting toxicity to healthy surrounding tissues. This can be achieved only with superior knowledge of radiologic anatomy and treatment planning. Educational resources designed to meet these specific needs are lacking. A web-based interactive module designed to improve residents' knowledge and application of key anatomy concepts pertinent to radiotherapy treatment planning was developed, and its effectiveness was assessed. Methods and Materials: The module, based on gynecologic malignancies, was developed in collaboration with a multidisciplinary team of subject matter experts. Subsequently, a multi-centre randomized controlled study was conducted to test the module's effectiveness. Thirty-six radiation oncology residents participated in the study; 1920 were granted access to the module (intervention group), and 17 in the control group relied on traditional methods to acquire their knowledge. Pretests and posttests were administered to all participants. Statistical analysis was carried out using paired t test, analysis of variance, and post hoc tests. Results: The randomized control study revealed that the intervention group's pretest and posttest mean scores were 35% and 52%, respectively, and those of the control group were 37% and 42%, respectively. The mean improvement in test scores was 17% (p < 0.05) for the intervention group and 5% (p = not significant) for the control group. Retrospective pretest and posttest surveys showed a statistically significant change on all measured module objectives. Conclusions: The use of an interactive e-learning teaching module for radiation oncology is an effective method to improve the radiologic anatomy knowledge and treatment planning skills of radiation oncology residents.

    Nurses can have an influence on primary and secondary prevention of skin cancer. Therefore, it is important to help them acquire knowledge and skills necessary to modify behavior in relation to skin cancers. The aim of this study was to examine effects of creating awareness through photographs and posters on knowledge and skills of skin self-examination in nursing students. The study had a quasi-experimental design with a pretest and a posttest in a single group. The study population included 249 last-year nursing students in Turkey. Non-probability sampling was used to reach the population. The study sample was composed of 201 students volunteering to participate in the study, and the response rate was 81 %. Of the students, 85.1 % (n = 171) were female and the mean age of the students was 22.18 ± 0.78 years. Of the students, 94.5 % did not know the asymmetry, border, color, diameter, evolution (ABCDE) criteria on the pretest, but this rate decreased to 20.9 % on the posttest. The mean score for knowledge of symptoms of skin cancer was 10.95 ± 1.37 on the pretest and 11.48 ± 0.90 on the posttest. There was a significant linear increase in the scores for knowledge of the symptoms (F = 7.874, p < 0.001) after the intervention with photographs and posters. The students were observed to learn the ABCDE criteria and had increased knowledge of skin cancer symptoms after the intervention using photographs and posters. Photographs and posters are effective tools which can be used to increase awareness of skin self-examination.

    Athletic training educators often anecdotally suggest that athletic training students enhance their learning by teaching their peers. However, peer-assisted learning (PAL) has not been examined within athletic training education to provide evidence for PAL's current use or for its use as a pedagogic tool. To assess the effectiveness of intentional, formal PAL on the performance of psychomotor skills and to identify students' perceptions of PAL. Randomized, pretest-posttest experimental design. Athletic Training Research and Education Laboratory. Fifty-one undergraduate students (27 athletic training majors, 24 nonmajors). Review sessions led by either an Approved Clinical Instructor or peer tutor. We assessed pretest and posttest performance scores (number of correct skills) and the amount of time to complete the psychomotor skills in 3 categories of orthopaedic evaluation of the hand and wrist for subjects assigned to either a peer tutor or an Approved Clinical Instructor review group. Using the Athletic Training Peer-Assisted Learning Assessment Survey, we evaluated the perceptions of students assigned to the peer-tutor group regarding the benefits of, and preferences for, PAL. Differences in the pretest-posttest skill scores were noted in both groups (P psychomotor skills with peer tutors than with the laboratory instructor, and many students (n = 12, 44.4%) felt more self-confident when practicing psychomotor skills with a peer tutor. Peer-assisted learning appears to be a valid method for improving athletic training psychomotor skills. Peers can be resources for practicing clinical skills and report benefiting from the collaboration. Peer-assisted learning should be deliberately integrated into athletic training education programs to enhance student learning and collaboration.

    Training in intercultural competency for health care professionals is necessary to bring greater balance to the disparity currently found among those needing health care. The purpose of this study was to determine what, if any, improvements in cultural competency were measurable in physician assistant (PA) students as they matriculated, using the Multicultural Awareness, Knowledge and Skills Survey-Revised as a pretest upon program entry and again as a posttest on the final day of the program. Ninety-three PA students from four successive classes graduating from a private midwest college between 2003 and 2007 participated in the pre and post measurements. All students were enrolled in specific didactic studies and clinical experiences in cultural sensitivity and competency. The results demonstrated significant improvement in knowledge (pretest 2.63, posttest 2.76, p=0.001) and skills (pretest 2.63, posttest 2.93, pIntercultural Development Inventory was administered to the most recent graduating class to further explore these results. This cohort showed the highest scores (group mean 3.58 on scale of 1-5) in the Minimization developmental stage, which emphasizes cultural commonality over cultural distinctions. Enhanced curricular instruction such as exploring cultural assessment methods and controversies in health care differences, combined with increased clinical experiences with diverse cultures, are recommended to help move students past the minimization stage to gain greater cultural competency.

    Working memory (WM) capacity is highly correlated with general cognitive ability and has proven to be an excellent predictor for academic success. Given that WM can be improved by training, our aim was to test whether WM training benefited academic abilities in elementary-school children. We examined 28 participants (mean age = 8.3 years, SD = 0.4) in a pretest-training-posttest-follow-up design. Over 14 training sessions, children either performed adaptive WM training (training group, n = 14) or nonadaptive low-level training (active control group, n = 14) on the same tasks. Pretest, posttest, and follow-up at 3 months after posttest included a neurocognitive test battery (WM, task switching, inhibition) and standardized tests for math and reading abilities. Adaptive WM training resulted in larger training gains than nonadaptive low-level training. The benefits induced by the adaptive training transferred to an untrained WM task and a standardized test for reading ability, but not to task switching, inhibition, or performance on a standardized math test. Transfer to the untrained WM task was maintained over 3 months. The analysis of individual differences revealed compensatory effects with larger gains in children with lower WM and reading scores at pretest. These training and transfer effects are discussed against the background of cognitive processing resulting from WM span training and the nature of the intervention.

    This study evaluated whether critical thinking ability can be improved through participation in occupational therapy (OT) and physical therapy (PT) curricula. The researchers compared levels of the critical thinking skills of OT and PT students at the beginning and end of their programs to determine whether changes occurred and to examine facets of the curricula that may have caused the differences. The curricula include teaching strategies of problem-based learning modules, small group discussion and problem-solving, case studies, clinical observation, and evidence-based practice assignments, as well as teaching about critical thinking as a process in itself. Fifty OT and PT students completed the Watson-Glaser Critical Thinking Appraisal at the beginning and end of 20 mos of the academic phase of their master's degree programs. Researchers analyzed the data using a one-way repeated-measures ANOVA. Results showed no differences between OT and PT students on the pretest or post-test and no differences for PT students between the pretest and post-test. OT students' scores increased significantly from pretest to post-test. The influence of the timing of teaching critical thinking skills in the resulting differences between the two curricula, as well as the validity of the Watson-Glaser Critical Thinking Appraisal is a valid measure of critical thinking changes in allied health students are discussed.

    Child sexual abuse and exploitation are an increasing public health problem. In spite of the fact that nurses are in a unique position to identify and intervene in the lives of children suffering from abuse due to their role in providing health care in a variety of settings, nursing curricula does not routinely include this focus. The goal was to document the effectiveness of the Stewards of Children child sexual abuse training as an effective educational intervention to increase the knowledge level of undergraduate nursing students on how to prevent, recognize, and react responsibly to child sexual abuse and trafficking. Undergraduate nursing students were required to take the Stewards of Children training in their last semester prior to graduation. Students in the study were given a pre-test prior to the class and a post-test following the class. Pre- and post-tests were graded and the results were compared along with an item indicating the participants' perception of the educational intervention in improving their confidence and competence in this area. Data analysis revealed that post-test scores following training were significantly improved: pre-test mean=45.5%; post-test mean score=91.9%. The statistical significance of the improvement was marked, pChildren training. Students also reported a high level of confidence in how to prevent abuse and react skillfully when child sexual abuse had occurred. The authors concluded that Stewards of Children is an effective option to educate nursing students on this topic. Copyright © 2017. Published by Elsevier Ltd.

    Rotating residents represent a significant proportion of housestaff in academic emergency departments (EDs), yet they rarely receive targeted didactic education during their emergency medicine (EM) rotations. The goals of this study were: 1) to determine the effectiveness of an online didactic curriculum in improving EM knowledge among rotating residents and 2) to assess rotating resident satisfaction with this curriculum. The authors created an online lecture series of six EM subject areas targeted to rotating residents called the Northwestern University Rotating Resident Curriculum (NURRC). All rotating residents at the study site were eligible, written consent was obtained, and the study was approved by the institutional review board. Consenting participants were pretested with a 42-question multiple-choice examination and then randomized to two groups: one with access to the NURRC during the first 2 weeks of the rotation (experimental) and one without (control). Halfway through the rotation, all participants were post-tested with a different multiple-choice examination, and the controls were then granted NURRC access. The primary outcome was the difference between pretest and posttest scores (score delta). The t-test was used to compare mean scores, and a linear regression model was used to determine the association of NURRC access on score delta after adjustment for pretest type and resident type. A postintervention survey was administered at the end of the rotation to assess satisfaction with the NURRC and collect suggestions for improvement. Fifty-four rotating residents were enrolled: 29 in the experimental group and 25 in the control group. There was no significant difference in pretest scores between the two groups. Mean score delta was 17.3% in the experimental group and 1.6% in the control group, an absolute difference of 15.7% (95% confidence interval [CI]=10% to 22%). After adjustment for resident type and pretest type, the only variable positively

    Discriminating incipient Alzheimer's disease (AD) from major depression (MD) and age related memory decline is a challenge in clinical practice. Since AD is characterized by an early loss of neuronal and functional plasticity, a dynamic test strategy, such as the testing-the-limits (TtL) approach, that measures learning capacity can be a helpful diagnostic tool. To evaluate this, a short recognition paradigm consisting of a pre-test (baseline) and two post-test conditions with an interposed encoding instruction was developed and administered to individuals with incipient AD (n = 19; Mini Mental Status Examination (MMSE) 26.5), patients with depressive disorders (n = 11; MMSE 30), and healthy controls (n = 11; MMSE 30). In addition, participants completed a set of traditional neuropsychological tests that focused on the subjects' cognitive baseline performance. Intergroup comparisons (Kruskal-Wallis, U test) revealed significantly higher post-test failure rates in AD patients. Pre-test performance of MD and AD patients did not differ. Intra-group comparisons (Friedman, Wilcoxon test) showed that all three subject samples benefit from intervention in post-test 1. In contrast to MD and healthy individuals, who revealed significantly lower failure rates in post-test 2 compared to the pre-test, AD patients did not improve. Out of the 15 traditional test scores obtained, only two discriminated simultaneously between AD and each of the other groups. Our data confirm the finding of an impaired cognitive plasticity already present in very early stages of AD and illustrate the efficiency of a dynamic test approach in identifying incipient dementia.

    This meta-analysis examined the effects of process-based executive-function and working memory training (49 articles, 61 independent samples) in older adults (> 60 years). The interventions resulted in significant effects on performance on the trained task and near-transfer tasks; significant results were obtained for the net pretest-to-posttest gain relative to active and passive control groups and for the net effect at posttest relative to active and passive control groups. Far-transfer effects were smaller than near-transfer effects but were significant for the net pretest-to-posttest gain relative to passive control groups and for the net gain at posttest relative to both active and passive control groups. We detected marginally significant differences in training-induced improvements between working memory and executive-function training, but no differences between the training-induced improvements observed in older adults and younger adults, between the benefits associated with adaptive and nonadaptive training, or between the effects in active and passive control conditions. Gains did not vary with total training time. © The Author(s) 2014.

    Malaria is endemic in Nigeria, with significant records of mortality and morbidity. Adequate community involvement is central to a successful implementation of malaria control programs. This study assessed the effects of a training programme on knowledge of malaria prevention and control among community role model care givers. A descriptive cross sectional study of a pre-and post-test design method was conducted among 400 eligible community members in Osun State. Training was given in the form of organized lectures, health education and practical demonstration sessions. Scores of pre-test and post-test conducted after four months interval were compared. Multistage sampling method was adopted in selecting study participants, while data was analyzed using the SPSS software version 17.0. Mean age was 43.8 (±1.4) years. Average knowledge score of cause, transmission, risk factors and consequences, awareness of common symptoms and preventive practices improved during post-training test when compared with pr-training test. The overall descriptive mean knowledge score in pre-test and post-test were 2.1 and 3.5 respectively out of an average maximum score of 5.0, giving an increment of 66.7%. Role model care givers with formal education were twice and three times more likely to know about disease 'transmission' (OR 1.9, 95%CI 0.11-0.19, p=0.002) and 'consequences' (OR 2.9, 95%CI 0.25-0.65, p=0.040) respectively compared to those without formal education. Training on malaria improved the knowledge of malaria prevention and control among role model community care givers towards a successful implementation of malaria control programmes.

    Full Text Available Abstract Background This prospective study compares the use of interactive multimedia eBooks (IME with traditional PowerPoint (TPP for teaching cell morphology of blood and bone marrow. Methods Fifty-one interns from three Taiwan medical schools training by a single teacher in the pediatric hematology department of Kaohsiung Chang Gung Memorial Hospital, Taiwan, participated in this study. 25 interns were allocated for training with a traditional PowerPoint atlas and 26 interns for training with an interactive multimedia eBook atlas. Learning outcomes were examined by pre-test and post-test using the CellQuiz of CellAtlas App. Attitudes and perceptions were collected by survey questions regarding interest, motivation and effectiveness. Results There was no difference in the pre-test scores between TPP and IME groups (mean score 27.0 versus 27.9, p = 0.807. However, the interns in the interactive multimedia eBook group achieved significantly better scores in the post-test than the ones in the PowerPoint group (mean score 103.2 versus 70.6; p < 0.001. Overall results of interest, motivation and effectiveness were strongly positive in the multimedia eBook group. Conclusions Our data supports that interactive multimedia eBooks are more effective than PowerPoint to facilitate learning of cell morphology of blood and bone marrow.

    Full Text Available This research is aimed at: (1 producing an appropriate e-learning for English language studies in vocational high school, (2 evaluating the suitability of the developed e-learning in terms of appropriateness, accuracy and clarity, screen presentation and design, and appropriateness of the team builder module aspect, and (3 evaluating the effectiveness of the e-learning in practical application. This research and development (R&D study used Alessi and Trollip’s model rearranged following ADDIE model, where the development of instruction followed Dick and Carey’s model and the need assessment procedures were adapted from Lee & Owens. Overall appropriateness and quality of the e-learning from alpha testing is ‘very appropriate’ and from beta testing is ‘excellent’. Alpha testing reveals that, the Team Builder Module is ‘very appropriate’ and beta testing reveals that, its overall quality is ‘excellent’. The e-learning is highly effective. The average score of the students raises 3.82 points (or 42.44% in the post-test from pre-test score. The minimum score of the post-test (i.e. 8 is more than the maximum score of the pre-test (i.e. 7, so it is concluded that the use of e-learning does not deteriorate the performance of the students, but improves their performance.

    We investigated the effectiveness of a freely available agent based, modeling program as a learning tool for seventh and eighth grade students to explore the greenhouse effect without added curriculum. The investigation was conducted at two Maine middle-schools with 136 seventh-grade students and 11 eighth-grade students in eight classes. Students were given a pre-test that consisted of a concept map, a free-response question, and multiple-choice questions about how the greenhouse effect influences the Earth's temperature. The computer model simulates the greenhouse effect and allows students to manipulate atmospheric and surface conditions to observe the effects on the Earth’s temperature. Students explored the Greenhouse Effect model for approximately twenty minutes with only two focus questions for guidance. After the exploration period, students were given a post-test that was identical to the pre-test. Parametric post-test analysis of the assessments indicated middle-school students gained in their understanding about how the greenhouse effect influences the Earth's temperature after exploring the computer model for approximately twenty minutes. The magnitude of the changes in pre- and post-test concept map and free-response scores were small (average free-response post-test score of 7.0) compared to an expert's score (48), indicating that students understood only a few of the system relationships. While students gained in their understanding about the greenhouse effect, there was evidence that students held onto their misconceptions that (1) carbon dioxide in the atmosphere deteriorates the ozone layer, (2) the greenhouse effect is a result of humans burning fossil fuels, and (3) infrared and visible light have similar behaviors with greenhouse gases. We recommend using the Greenhouse Effect computer model with guided inquiry to focus students’ investigations on the system relationships in the model.

    Multiple training modalities for laparoscopy have different advantages, but little research has been conducted on the benefit of a training program that includes multiple different training methods compared to one method only. This study aimed to evaluate benefits of a combined multi-modality training program for surgical residents. Laparoscopic cholecystectomy (LC) was performed on a porcine liver as the pre-test. Randomization was stratified for experience to the multi-modality Training group (12 h of training on Virtual Reality (VR) and box trainer) or Control group (no training). The post-test consisted of a VR LC and porcine LC. Performance was rated with the Global Operative Assessment of Laparoscopic Skills (GOALS) score by blinded experts. Training (n = 33) and Control (n = 31) were similar in the pre-test (GOALS: 13.7 ± 3.4 vs. 14.7 ± 2.6; p = 0.198; operation time 57.0 ± 18.1 vs. 63.4 ± 17.5 min; p = 0.191). In the post-test porcine LC, Training had improved GOALS scores (+ 2.84 ± 2.85 points, p < 0.001), while Control did not (+ 0.55 ± 2.34 points, p = 0.154). Operation time in the post-test was shorter for Training vs. Control (40.0 ± 17.0 vs. 55.0 ± 22.2 min; p = 0.012). Junior residents improved GOALS scores to the level of senior residents (pre-test: 13.7 ± 2.7 vs. 18.3 ± 2.9; p = 0.010; post-test: 15.5 ± 3.4 vs. 18.8 ± 3.8; p = 0.120) but senior residents remained faster (50.1 ± 20.6 vs. 25.0 ± 1.9 min; p < 0.001). No differences were found between groups on the post-test VR trainer. Structured multi-modality training is beneficial for novices to improve basics and overcome the initial learning curve in laparoscopy as well as to decrease operation time for LCs in different stages of experience. Future studies should evaluate multi-modality training in comparison with single modalities. German Clinical Trials Register DRKS00011040.

    Full Text Available Learning plays an important role in developing nursing skills and right care-taking. The Present study aims to evaluate two learning methods based on team –based learning and lecture-based learning in learning care-taking of patients with diabetes in nursing students. In this quasi-experimental study, 64 students in term 4 in nursing college of Bukan and Miandoab were included in the study based on knowledge and performance questionnaire including 15 questions based on knowledge and 5 questions based on performance on care-taking in patients with diabetes were used as data collection tool whose reliability was confirmed by cronbach alpha (r=0.83 by the researcher. To compare the mean score of knowledge and performance in each group in pre-test step and post-test step, pair –t test and to compare mean of scores in two groups of control and intervention, the independent t- test was used. There was not significant statistical difference between two groups in pre terms of knowledge and performance score (p=0.784. There was significant difference between the mean of knowledge scores and diabetes performance in the post-test in the team-based learning group and lecture-based learning group (p=0.001. There was significant difference between the mean score of knowledge of diabetes care in pre-test and post-test in base learning groups (p=0.001. In both methods team-based and lecture-based learning approaches resulted in improvement in learning in students, but the rate of learning in the team-based learning approach is greater compared to that of lecturebased learning and it is recommended that this method be used as a higher education method in the education of students.

    Skin care is an important responsibility of nurse aides in long-term care facilities, and the nursing knowledge, attitudes, and skills of these aides significantly affects quality of care. However, the work schedule of nurse aides often limits their ability to obtain further education and training. Therefore, developing appropriate and effective training programs for nurse aides is critical to maintaining and improving quality of care in long-term care facilities. This study investigates the effects of multimedia assisted instruction on the skin care learning of nurse aides working in long-term care facilities. A quasi-experimental design and convenient sampling were adopted in this study. Participants included 96 nurse aides recruited from 5 long-term care facilities in Taoyuan County, Taiwan. The experimental group received 3 weeks of multimedia assisted instruction. The control group did not receive this instruction. The Skin Care Questionnaire for Nurse Aides in Long-term Care Facilities and the Skin Care Behavior Checklist were used for assessment before and after the intervention. (1) Posttest scores for skin care knowledge, attitudes, behavior, and the skin care checklist were significantly higher than pretest scores for the intervention group. There was no significant difference between pretest and posttest scores for the control group. (2) A covariance analysis of pretest scores for the two groups showed that the experimental group earned significantly higher average scores than their control group peers for skin care knowledge, attitudes, behavior, and the skin care checklist. The multimedia assisted instruction demonstrated significant and positive effects on the skin care leaning of nurse aides in long-term care facilities. This finding supports the use of multimedia assisted instruction in the education and training of nurse aides in long-term care facilities in the future.

    Full Text Available Background: Physicians require extensive training to achieve proficiency in mechanical ventilator (MV management of the critically ill patients. Guided self-directed learning (GSDL is usually the method used to learn. However, it is unclear if this is the most proficient approach to teaching mechanical ventilation to critical care fellows. We, therefore, investigated whether critical care fellows achieve higher scores on standardized testing and report higher satisfaction after participating in a hands-on tutorial combined with GSDL compared to self-directed learning alone. Methods: First-year Pulmonary and Critical Care Medicine (PCCM fellows (n=6 and Critical Care Internal Medicine (CCIM (n=8 fellows participated. Satisfaction was assessed using the Likert scale. MV knowledge assessment was performed by administering a standardized 25-question multiple choice pre- and posttest. For 2 weeks the CCIM fellows were exposed to GSDL, while the PCCM fellows received hands-on tutoring combined with GSDL. Results: Ninety-three percentage (6 PCCM and 7 CCIM fellows, total of 13 fellows completed all evaluations and were included in the final analysis. CCIM and PCCM fellows scored similarly in the pretest (64% vs. 52%, p=0.13. Following interventions, the posttest scores increased in both groups. However, no significant difference was observed based on the interventions (74% vs. 77%, p=0.39. The absolute improvement with the hands-on-tutoring and GSDL group was higher than GSDL alone (25% vs. 10%, p=0.07. Improved satisfaction scores were noted with hands-on tutoring. Conclusions: Hands-on tutoring combined with GSDL and GSDL alone were both associated with an improvement in posttest scores. Absolute improvement in test and satisfaction scores both trended higher in the hands-on tutorial group combined with GSDL group.

    Background Little empirical data are available on the extent to which capacity-building programs in research ethics prepare trainees to apply ethical reasoning skills to the design, conduct, or review of research. A randomized controlled trial was conducted in Botswana in 2010 to assess the effectiveness of a case-based intervention using email to augment in-person seminars. Methods University faculty and current and prospective IRB/REC members took part in a semester-long training program in research ethics. Participants attended two 2-day seminars and were assigned at random to one of two on-line arms of the trial. Participants in both arms completed on-line international modules from the Collaborative Institutional Training Initiative. Between seminars, intervention-arm participants were also emailed a weekly case to analyze in response to set questions; responses and individualized faculty feedback were exchanged via email. Tests assessing ethics knowledge were administered at the start of each seminar. The post-test included an additional section in which participants were asked to identify the ethical issues highlighted in five case studies from a list of multiple-choice responses. Results were analyzed using regression and ANOVA. Results Of the 71 participants (36 control, 35 intervention) enrolled at the first seminar, 41 (57.7%) attended the second seminar (19 control, 22 intervention). In the intervention arm, 19 (54.3%) participants fully completed and 8 (22.9%) partially completed all six weekly cases. The mean score was higher on the post-test (30.3/40) than on the pre-test (28.0/40), and individual post- and pre-test scores were highly correlated (r = 0.65, p  0.84), but intervention-arm subjects who completed all assigned cases answered an average of 3.2 more questions correctly on the post-test than others, controlling for pre-test scores (p = 0.003). Conclusions Completion of the case-based intervention improved respondents’ test

    This article reports on a pre- and post-test experimental study with 4504 refugees in 38 camps across nine destination countries. The aim was to examine the role of spirituality and a specially designed spiritual education programme in promoting mental health of refugees. A pre- and post-test experimental design has been used with three scales to examine the outcome measures: (1) the trauma screening questionnaire (2) life orientation test-revised and (3) mental health inventory-38. Results showed that compared with pre-test scores, the average post-test scores of the refugees on the trauma questionnaire were lower, and higher on optimism measure, and mental health inventory. Voluntary participation, full attendance and self-practice willingness were favourable predictors of refugee mental health. Hierarchical regression model showed that self-practice willingness was the most important predictor of positive mental health of refugees. Findings make a case for interventions for refugees grounded in cultural competency and spirituality.

    Full Text Available Background: Humans are hard-wired to pay attention to violent and sexual cues. Because humans have limited attention capacity, attention allocated to violent and sexual cues decreases attention that can be allocated to encoding important information in school. This study examined the effects of exposure to violent and sexual media on general school performance and Test of English as a Foreign Language (TOEFL scores in Turkish youth. Methods: The relationship between exposure to violent and sexual media on school performance was assessed in a sample of 1545 Turkish adolescents. Then, we compared the TOEFL scores of 143 Turkish boys aged 14 to 18 divided in 71 living in dormitories in which consumption of media was strictly regulated and 72 living at home. Results: A significant negative relationship was found between exposure to violent/sexual media and school success. The effects remained significant even after controlling for the total amount of media exposure. In addition, boys living in the dormitory in which consumption of media was strictly regulated outscored those living at home on the TOEFL post-test immediately after the end of the study, and on a delayed post-test one week later. Conclusions: Because there was no difference between boys living at home and those living in a dormitory on the pre-test, the post-test and delayed post-test differences cannot be attributed to initial differences in English language proficiency. These results suggest that exposure to violent and sexual media impairs adolescent school performance and foreign language memory.

    This study focuses on clinically assigned prospective estimated pretest probability and pretest perception of legal risk as independent variables in the ordering of multidetector computed tomographic (MDCT) head scans. Our primary aim is to measure the association between pretest probability of a significant finding and pretest perception of legal risk. Secondarily, we measure the percentage of MDCT scans that physicians would not order if there was no legal risk. This study is a prospective, cross-sectional, descriptive analysis of patients 18 years and older for whom emergency medicine physicians ordered a head MDCT. We collected a sample of 138 patients subjected to head MDCT scans. The prevalence of a significant finding in our population was 6%, yet the pretest probability expectation of a significant finding was 33%. The legal risk presumed was even more dramatic at 54%. These data support the hypothesis that physicians presume the legal risk to be significantly higher than the risk of a significant finding. A total of 21% or 15% patients (95% confidence interval, ±5.9%) would not have been subjected to MDCT if there was no legal risk. Physicians overestimated the probability that the computed tomographic scan would yield a significant result and indicated an even greater perceived medicolegal risk if the scan was not obtained. Physician test-ordering behavior is complex, and our study queries pertinent aspects of MDCT testing. The magnification of legal risk vs the pretest probability of a significant finding is demonstrated. Physicians significantly overestimated pretest probability of a significant finding on head MDCT scans and presumed legal risk. Copyright © 2012 Elsevier Inc. All rights reserved.

    Recognizing facial expressions is an important social skill. In some psychological disorders such as schizophrenia, loss of this skill may complicate the patient's daily life. Prior research has shown that information technology may help to develop facial expression recognition skills through educational software and games. To examine if a computer game designed for teaching facial expressions would improve facial expression recognition skills of patients with schizophrenia. We developed a website composed of eight serious games. Thirty-two patients were given a pre-test composed of 21 facial expression photographs. Eighteen patients were in the study group while 14 were in the control group. Patients in the study group were asked to play the games on the website. After a period of one month, we performed a post-test for all patients. The median score of the correct answers was 17.5 in the control group whereas it was 16.5 in the study group (of 21) in pretest. The median post-test score was 18 in the control group (p=0.052) whereas it was 20 in the study group (pgames may be used for the purpose of educating people who have difficulty in recognizing facial expressions.

    Full Text Available This research was done to analyze the effects of Coping with Burnout Program, developed on the basis of Solution-Focused Brief Therapy on the burnout levels of university students. To select the subjects that would participate in the research, Maslach Burnout Inventory­­–Student Survey was applied on 461 university students from the University of Sakarya. As a result of pre-interviews, 24 students who had experienced student burnout voluntarily participated in a Coping with Burnout Program. The students were randomly appointed to one of the experimental and control groups. At this stage, a six-session Coping with Burnout Program developed by the researcher was applied on the students from the experimental group. No application was performed on the students from the control group. A 2x3 design (experimental/ control groups X pretest/ posttest/ follow up was used in the research. The scores from the Maslach Burnout Inventory–Student Survey formed the dependent variable of the research, and the application of Coping with Burnout Program formed the independent variable of the research. The scale used in the research was applied on the groups as pretest two weeks before the sessions started, and as posttest two weeks after the sessions ended, and as follow-up two months after the posttest in order to determine the resistance of the experimental process. In the analysis of the data obtained through these processes, two-way analysis of variance (ANOVA was used to determine whether or not there was a significant difference between groups and the survey. The data obtained through the research proved that the Coping with Burnout Program decreased the burnout levels of the students in the experimental group as were determined with the Maslach Burnout Inventory–Student Survey, and follow up tests showed that the situation remained the same. It was seen that there was no significant difference between the scores of the participants of the control

    Full Text Available Abstract Background Team-based learning (TBL, a new active learning method, has not been reported for neurology education. We aimed to determine if TBL was more effective than passive learning (PL in improving knowledge outcomes in two key neurology topics - neurological localization and neurological emergencies. Methods We conducted a modified crossover study during a nine-week internal medicine posting involving 49 third-year medical undergraduates, using TBL as the active intervention, compared against self-reading as a PL control, for teaching the two topics. Primary outcome was the mean percentage change in test scores immediately after (post-test 1 and 48 hours after TBL (post-test 2, compared to a baseline pre-test. Student engagement was the secondary outcome. Results Mean percentage change in scores was greater in the TBL versus the PL group in post-test 1 (8.8% vs 4.3%, p = 0.023 and post-test 2 (11.4% vs 3.4%, p = 0.001. After adjustment for gender and second year examination grades, mean percentage change in scores remained greater in the TBL versus the PL group for post-test 1 (10.3% vs 5.8%, mean difference 4.5%,95% CI 0.7 - 8.3%, p = 0.021 and post-test 2 (13.0% vs 4.9%, mean difference 8.1%,95% CI 3.7 - 12.5%, p = 0.001, indicating further score improvement 48 hours post-TBL. Academically weaker students, identified by poorer examination grades, showed a greater increase in scores with TBL versus strong students (p Conclusions Compared to PL, TBL showed greater improvement in knowledge scores, with continued improvement up to 48 hours later. This effect is larger in academically weaker students. TBL is an effective method for improving knowledge in neurological localization and neurological emergencies in undergraduates.

    Caregivers in long-term care (LTC) facilities have to uphold a positive attitude toward the elderly, so they will be more willing to provide the elderly with care of higher quality. Theory of Gerotranscendence is a theory which can assist the elderly in developing more mature and intellectual state of mind. It is hoped that the caregivers who receive gerotranscendence education may apply its concept to the care for the elderly. To evaluate the effects of the gerotranscendence educational program on caregivers' gerotranscendence recognition, attitude towards aging, and behavioral intention towards caring for the elderly. A quasi-experimental design with repeated measures was conducted. A total of 41 caregivers in LTC facilities participated and completed the study. Participants were invited to participate in a 2-day gerotranscendence educational program, and measurement took place at baseline, the end of the program (post-test) and three months after the program (follow-up test). The research tools included Gerotranscendence Recognition Scale-Chinese version, Aging Attitude scale, and Caregivers' Behavioral Intention Scale. This study used GLM repeated measures to perform analysis. There was a statistically significant difference in three repeated measures of participants' gerotranscendence recognition and behavior intention toward caring for the elderly (p=.002, .002, respectively) but not in the aging attitude score (p=.21). The post hoc comparison showed that the scores of these two outcomes in the post-test were significantly higher than those in the pre-test (p=.000; .024). However, the scores in the follow-up test were almost the same as those in the pre-test. The gerotranscendence educational program had timely effects on caregivers' gerotranscendence recognition and behavioral intention towards aging, and so caregivers working in LTC facilities may require ongoing training in the gerotranscendence educational program to ensure that these positive effects

    Suicide ranks as the third leading cause of death among youth aged 15-24 years. Schools provide ideal opportunities for suicide prevention efforts. However, research is needed to identify programs that effectively impact youth suicidal ideation and behavior. This study examined the immediate and 3-month effect of Surviving the Teens® Suicide Prevention and Depression Awareness Program on students' suicidality and perceived self-efficacy in performing help-seeking behaviors. High school students in Greater Cincinnati schools were administered a 3-page survey at pretest, immediate posttest, and 3-month follow-up. A total of 1030 students participated in the program, with 919 completing matched pretests and posttests (89.2%) and 416 completing matched pretests and 3-month follow-ups (40.4%). Students were significantly less likely at 3-month follow-up than at pretest to be currently considering suicide, to have made a suicidal plan or attempted suicide during the past 3 months, and to have stopped performing usual activities due to feeling sad and hopeless. Students' self-efficacy and behavioral intentions toward help-seeking behaviors increased from pretest to posttest and were maintained at 3-month follow-up. Students were also more likely at 3-month follow-up than at pretest to know an adult in school with whom they felt comfortable discussing their problems. Nine in 10 (87.3%) felt the program should be offered to all high school students. The findings of this study lend support for suicide prevention education in schools. The results may be useful to school professionals interested in implementing effective suicide prevention programming to their students. © 2011, American School Health Association.

    With the increasing costs of physics experiments and simultaneous increase in availability and maturity of computational tools it is not surprising that computational fluid dynamics (CFD) is playing an increasingly important role, not only in post-test investigations, but also in the early stages of experimental planning. This paper describes a CFD-based effort executed in close collaboration between computational fluid dynamicists and experimentalists to develop a virtual experiment during the early planning stages of the Enhanced Injection and Mixing project at NASA Langley Research Center. This projects aims to investigate supersonic combustion ramjet (scramjet) fuel injection and mixing physics, improve the understanding of underlying physical processes, and develop enhancement strategies and functional relationships relevant to flight Mach numbers greater than 8. The purpose of the virtual experiment was to provide flow field data to aid in the design of the experimental apparatus and the in-stream rake probes, to verify the nonintrusive measurements based on NO-PLIF, and to perform pre-test analysis of quantities obtainable from the experiment and CFD. The approach also allowed for the joint team to develop common data processing and analysis tools, and to test research ideas. The virtual experiment consisted of a series of Reynolds-averaged simulations (RAS). These simulations included the facility nozzle, the experimental apparatus with a baseline strut injector, and the test cabin. Pure helium and helium-air mixtures were used to determine the efficacy of different inert gases to model hydrogen injection. The results of the simulations were analyzed by computing mixing efficiency, total pressure recovery, and stream thrust potential. As the experimental effort progresses, the simulation results will be compared with the experimental data to calibrate the modeling constants present in the CFD and validate simulation fidelity. CFD will also be used to

    Full Text Available Breaking bad news is one of the most burdensome tasks physicians face in their everyday practice. It becomes even more challenging in the context of HIV+ patients because of stigma and discrimination. The aim of the current study is to evaluate the quality of giving HIV seroconversion news according to SPIKES protocol. Numbers of 154 consecutive HIV+ patients from Imam Khomeini Hospital testing and counseling center were enrolled in this study. Patients were inquired about how they were given the HIV news and whether or not they received pre- and post-test counseling sessions. Around 51% of them were men, 80% had high school education, and 56% were employed. Regarding marital status, 32% were single, and 52% were married at the time of the interview. Among them, 31% had received the HIV news in a counseling center, and only 29% had pre-test counseling. SPIKES criteria were significantly met when the HIV news was given in an HIV counseling and testing center (P.value<0.05. Low coverage of HIV counseling services was observed in the study. SPIKES criteria were significantly met when the HIV seroconversion news was given in a counseling center. The need to further train staff to deliver HIV news seems a priority in the field of HIV care and treatment.

    Moral sensitivity is a life-long cognitive ability. It is expected that nurses who work in a professional purpose at "curing human beings" should have a highly developed moral sensitivity. The general opinion is that ethics education plays a significant role in this sense to enhance the moral sensitivity in terms of nurses' professional behaviors and distinguish ethical violations. This study was conducted as intervention research for the purpose of determining the effect of the ethics training on fourth-year students of the nursing department recognizing ethical violations experienced in the hospital and developing ethical sensitivity. The study was conducted with 50 students, with 25 students each in the experiment and control groups. Students in the experiment group were provided ethics training and consultancy services. The data were collected through the data collection form, which consists of questions on the socio-demographic characteristics and ethical sensitivity of the students, Moral Sensitivity Questionnaire, and the observation form on ethical principle violations/protection in the clinic environment. The data were digitized on the computer with the SPSS for Windows 13.0 program. The data were evaluated utilizing number, percentile calculation, paired samples t-test, Wilcoxon test, and the McNemar test. The total Moral Sensitivity Questionnaire pre-test score averages of students in the experiment group were determined to be 93.88 ± 13.57, and their total post-test score averages were determined to be 89.24 ± 15.90. The total pre-test score averages of students in the control group were determined to be 91.48 ± 17.59, and their total post-test score averages were determined to be 97.72 ± 19.91. In the study, it was determined that the post-training ethical sensitivity of students in the experiment group increased; however, this was statistically not significant. Furthermore, it was determined that the number of ethical principle protection

    In a previous study, we reported that the distribution of total depressive symptoms scores according to the Center for Epidemiologic Studies Depression Scale (CES-D) in a general population is stable throughout middle adulthood and follows an exponential pattern except for at the lowest end of the symptom score. Furthermore, the individual distributions of 16 negative symptom items of the CES-D exhibit a common mathematical pattern. To confirm the reproducibility of these findings, we investigated the distribution of total depressive symptoms scores and 16 negative symptom items in a sample of Japanese employees. We analyzed 7624 employees aged 20-59 years who had participated in the Northern Japan Occupational Health Promotion Centers Collaboration Study for Mental Health. Depressive symptoms were assessed using the CES-D. The CES-D contains 20 items, each of which is scored in four grades: "rarely," "some," "much," and "most of the time." The descriptive statistics and frequency curves of the distributions were then compared according to age group. The distribution of total depressive symptoms scores appeared to be stable from 30-59 years. The right tail of the distribution for ages 30-59 years exhibited a linear pattern with a log-normal scale. The distributions of the 16 individual negative symptom items of the CES-D exhibited a common mathematical pattern which displayed different distributions with a boundary at "some." The distributions of the 16 negative symptom items from "some" to "most" followed a linear pattern with a log-normal scale. The distributions of the total depressive symptoms scores and individual negative symptom items in a Japanese occupational setting show the same patterns as those observed in a general population. These results show that the specific mathematical patterns of the distributions of total depressive symptoms scores and individual negative symptom items can be reproduced in an occupational population.

    The present document deals with Relap5/Mod3.2 analysis of the International Standard Problem (ISP-42) exercise performed in PANDA facility on April 21-22, 1998. PANDA is installed at PSI (Paul Scherrer Institute). PANDA is a large-scale thermal-hydraulic test facility suitable for the simulation of passive containment for Advanced Light Water Reactors (ALWR). The work focuses phase A of the ISP-42 experiment, including the break in the main steam line, and the Passive Containment Cooling System Start-Up. The objective is to investigate the start-up phenomenology of passive cooling system when steam is injected into cold vessel filled with air and to observe the resulting system behavior. A detailed nodalization was set-up at the University of Pisa, in order to model 3-D flow paths with a 1-D code. The comparison between pre-test predictions and experimental data is discussed. Overall time behavior is reasonably well predicted, showing a rather good and robust overall code behavior in the simulation of the global test scenario. The results of a preliminary post-test analysis are discussed, including the comparison with the experimental data. (authors)

    Recent studies reveal deficiencies in stroke awareness and knowledge of risk factors among women. Existing stroke education interventions may not address common and sex-specific risk factors in the population with the highest stroke-related rate of mortality. This pilot study assessed the efficacy of a technology-enhanced, sex-specific educational program ("SISTERS") for women's knowledge of stroke. This was an experimental pretest-posttest design. The sample consisted of 150 women (mean age, 55 years) with at least 1 stroke risk factor. Participants were randomized to either the intervention (n = 75) or control (n = 75) group. Data were collected at baseline and at a 2-week posttest. There was no statistically significant difference in mean knowledge score (P = .67), mean confidence score (P = .77), or mean accuracy score (P = .75) between the intervention and control groups at posttest. Regression analysis revealed that older age was associated with lower knowledge scores (P < .001) and lower confidence scores (P < .001). After controlling for age, the SISTERS program was associated with a statistically significant difference in knowledge (P < .001) and confidence (P < .001). Although no change occurred overall, after controlling for age, there was a statistically significant benefit. Older women may have less comfort with technology and require consideration for cognitive differences.

    Full Text Available This research is an evaluation of the effectiveness of task-based syllabus on EFL learners’ language competence at a private university in Vietnam educational context. This research resorts to questionnaire survey, semi-structured interview, and pretest and posttest as instruments for data collection. The research findings revealed that a strength of the current task-based syllabus is the match between lesson topics and students’ expectations. However, the syllabus still created difficulties for students including insufficient vocabulary, unfamiliar structures, and lack of life knowledge. The effect of teaching with task-based syllabus on students’ language performance is also reflected through a significant difference in mean scores between the pretest and the posttest. This research provides an insight into the effectiveness of English teaching through task-based syllabus at a private university in Vietnam setting. It implies to teachers that they need to be sustainable change catalysts for more interesting syllabus for learners

    We evaluated the effects of a parenting program, Baby and You, on parenting knowledge, parenting morale, and social support using a single-group, pre-test, and post-test design with 159 Canadian mothers of infants aged 2 to 9 months old. Baby and You is a prevention-focused parenting program (PFPP) to improve maternal and infant health through education and social support. The 4-week curriculum focuses on infant development and safety, parent-child relationships, maternal self-care, and community resources. We computed repeated-measures ANOVAs separately for scores on Parenting Knowledge Scale, Parenting Moral Index, and Family Support Scale. We found a significant increase between pre-test and post-test on parenting knowledge, but not parenting morale or social support. Parenting morale may be a stable construct that shows little change over time. It may take more than 4 weeks of programming for mothers to identify and integrate new sources of social support. © The Author(s) 2014.

    The objective of the study was to demonstrate the effectiveness of a college course in preconception health and prenatal development at improving reproductive health awareness in college students. Students enrolled in the course completed pretest and posttest assessments and a course evaluation. Students' self-perception of awareness of the positive and negative factors that can affect pregnancy increased from 13% at the beginning of the course to 89 and 93% at the end of the course, respectively. Correspondingly, students' knowledge of course-related information improved across nearly all areas assessed. The average score among students increased from 67 to 90% correct from pretest to posttest. Course evaluation results indicated that over 94% of students found the course to be beneficial and informative. College courses are a practical way to disseminate reproductive and prenatal health information. Educating college students in these areas has clear benefits to both individual students and society and, as such, merits increased attention in college curricula.

    Full Text Available The aim of this study is to examine the effect of mind mapping activities on the maths and science skills of children 48 to 60 months of age. The study was designed using an experimental model with a pre-test post-test and a control group. Accordingly, the hypotheses of the study was that there would be meaningful differences in the values obtained from the pre-test and post-test scores in favor of the children working with mind maps compared to the ones who did not work with mind maps. In the examination of the development of mind maps, it was observed that as the children engaged in preparing mind maps, they used skills requiring high-level mind organization. Mind maps, which can be used in all areas of life, are believed to be supportive of children's development areas and to be an important strategy for children to adopt and experience during the time of childhood.

    Full Text Available Background According to the available evidence and experiments, problem-based learning is one of the most successful methods to achieve higher educational objectives. In this method, the discussion about the medical subjects to be learned by the students is based on a real clinical case and participation of the students. Various advantages and disadvantages of this method have been addressed in different studies. Purpose In order to evaluate the effect of this method in our educational framework, we compare two educational methods, problem-based learning and lecture-based learning, in terms of students• education and recall. Methods It is an experimental study. Two topics of basic immunology were chosen after holding discussion meetings. The students were divided randomly into two groups. Each topic was taught to the two groups of students using both methods alternately. Students' educational achievement was evaluated with pre-test and post-test exams. Four weeks after these sessions, short-assay exams were used to evaluate the students' recall. Results The difference of pre-test results between the two groups was not statistically significant, whereas the difference of post-test scores was statistically significant. There was no statistically significant difference in the students' recall between the two groups. Conclusion Considering the exchange of two methods between the two groups, the effect of personal differences was eliminated in this study, and since there is no significant difference in the pre-test scores, the difference of post-test results could be related to the effect of PBL. According to the results of this study and with conducting additional experiments, the problem-based learning could be adjusted with the specific educational framework in our country.

    Knowles, J. Geoff

    This research analyzed the effects of teacher professional development and lesson implementation in integrated Science, Technology, Engineering, and Math (STEM) on: 1.) Teacher self-efficacy and their confidence to teach specific STEM subjects; 2.) Teaching outcome expectancy beliefs concerning the impact of actions by teachers on student learning; and 3.) Teacher awareness of STEM careers. High school science and technology education teachers participating in the Teachers and Researchers Advancing Integrated Lessons in STEM (TRAILS) project experimental group attended a ten-day summer professional development institute designed to educate teachers in using an integrated STEM education model to implement integrated STEM lessons. The research design utilized a quasi-experimental nonequivalent comparison group design that incorporated an experimental group and an untreated comparison group with both pretest, posttest, and delayed posttest assessments on non-randomized participants. Teacher self-efficacy has been identified as a key factor in effective teaching and student learning, and teacher awareness of STEM careers impacts students as they consider career choices. The T-STEM Survey for teachers was given for the pretest and posttest assessments to measure attitudes and beliefs toward the specific constructs of this study. Significant effects of the TRAILS professional development were found in the teacher group (experimental or comparison) and teacher subject (technology or science) in pretest and posttest scores using cumulative link models for the constructs of teacher self-efficacy and beliefs to teach STEM subjects, teacher outcome expectancy beliefs, and teacher awareness of STEM careers. Effect sizes ranged from small to large varying by construct and assessment time. Highly significant p-values and effect sizes revealed impacts on science teachers were greater when teacher subject groups were analyzed separately.

    Didactic lectures are frequently used to improve compliance with practice guidelines. This study assessed the knowledge of health-care providers (HCPs) at a tertiary-care hospital of its evidence-based thromboprophylaxis guidelines and the impact of didactic lectures on their knowledge. The hospital launched a multifaceted approach to improve thromboprophylaxis practices, which included posters, a pocket-size guidelines summary and didactic lectures during the annual thromboprophylaxis awareness days. A self-administered questionnaire was distributed to HCPs before and after lectures on thromboprophylaxis guidelines (June 2010). The questionnaire, formulated and validated by two physicians, two nurses and a clinical pharmacist, covered various subjects such as risk stratification, anticoagulant dosing and the choice of anticoagulants in specific clinical situations. Seventy-two and 63 HCPs submitted the pre- and post-test, respectively (62% physicians, 28% nurses, from different clinical disciplines). The mean scores were 7.8 ± 2.1 (median = 8.0, range = 2-12, maximum possible score = 15) for the pre-test and 8.4 ± 1.8 for the post-test, P = 0.053. There was no significant difference in the pre-test scores of nurses and physicians (7.9 ± 1.7 and 8.2 ± 2.4, respectively, P = 0.67). For the 35 HCPs who completed the pre- and post-tests, their scores were 7.7 ± 1.7 and 8.8 ± 1.6, respectively, P = 0.003. Knowledge of appropriate anticoagulant administration in specific clinical situations was frequently inadequate, with approximately two-thirds of participants failing to adjust low-molecular-weight heparin doses in patients with renal failure. Education via didactic lectures resulted in a modest improvement of HCPs' knowledge of thromboprophylaxis guidelines. This supports the need for a multifaceted approach to improve the awareness and implementation of thromboprophylaxis guidelines.

    Providing efficient basic life support (BLS) training is crucial for practicing nurses who provide direct patient care. Nevertheless, data addressing the impact of BLS courses on the skills and performance of Jordanian nurses are scarce. This study aimed to assess the effectiveness of a BLS simulation training on Jordanian nurses' skill improvement in cardiopulmonary resuscitation. A prospective quasi-experimental, single group pretest-posttest design was used to study the effect of BLS simulation; using a 9-item checklist; on the spot training; American Heart Association, on a group of Jordanian nurses. A pre-test was conducted following a CPR scenario to test the skills using 9-item checklist extrapolated from the American Heart Association guidelines. After debriefing, an interactive on spot training was provided. Later, participants undertook an unscheduled post-test after four weeks that included the same nine items. Thirty registered nurses with a mean clinical experience of 6.1years participated in the study. Comparing pre-test (M=4.6, SD=2.9, range=0 to 9) with post-test results (M=7.5, SD=1.7, range=4 to 9) showed an overall improvement in skills and BLS scores after the simulation training program (t=7.4, df=29, pskills and performance among Jordanian nurses. A refreshment BLS training session for nurses is highly recommended to guarantee nurses' preparedness in actual CPR scenarios. Copyright © 2015 Elsevier Ltd. All rights reserved.

    We compared the cost effectiveness of recent approaches [coronary angiography and calcium scoring using computed tomography (CT) and stress magnetic resonance imaging (MRI)] to the diagnosis of coronary artery disease (CAD) with those of the traditional diagnostic modalities [conventional angiography (CATH), exercise ECG, and stress echocardiography] using a decision tree model. For patients with a 10% to 50% pretest likelihood of coronary artery disease, non-invasive coronary angiography using CT was the most cost effective approach, with costs per correctly identified CAD patient of EUR4,435 (10% likelihood) to EUR1,469 (50% likelihood). Only for a pretest likelihood of 30% to 40% was calcium scoring using CT more cost effective than any of the traditional diagnostic modalities, while MRI was not cost effective for any pretest likelihood. At a pretest likelihood of 60%, CT coronary angiography and CATH were equally effective, while CATH was most cost effective for a pretest likelihood of at least 70%. In conclusion, up to a pretest likelihood for coronary artery disease of 50%, CT coronary angiography is the most cost-effective procedure, being superior to the other new modalities and the most commonly used traditional diagnostic modalities. With a very high likelihood for disease (above 60%), CATH is the most effective procedure from the perspective of society. (orig.)

    Abstract Objective: To describe the development and testing of a module to improve consent administrators’ skills when obtaining research consent from culturally and linguistically diverse and low literacy populations. Design: Development and psychometric testing of video module including community vignettes. Methods: Following initial content, face, and construct validity testing by experts, a field trial was conducted with pre‐ and postknowledge tests and satisfaction surveys completed by 112 consent administrators. Results: Mean score out of a possible 10 on pretest was 8.6 (±standard deviation [SD], 1.55) and on posttest was 9.1 (±SD, 1.2; paired t‐test 95% confidence interval of difference: –0.18 to –0.88; two‐tailed p = 0.003). The average years of experience with obtaining consent was 6.42 years (range: 0–35), but years of experience was not significantly associated with either pre‐ or posttest scores (p = 0.82 and 0.44, respectively). Most user evaluations were positive, although suggestions for improvements were made. Conclusion: Although pretest scores were relatively high, training needs of research consent administrators for consenting diverse and low literacy populations may be unmet. We urge that institutional review boards, researchers, policymakers, educators, and bioethicists address the training needs of research consent administrators and we offer this training module as one potential resource and adjunct to such training.

    Renner, Jonathan Christopher

    Some teens may prefer using a self-directed, constructivist, and technologic approach to learning rather than traditional classroom instruction. If it can be demonstrated, educators may adjust their teaching methodology. The guiding research question for this study focused on how augmented reality affects high school students' learning outcomes in chemistry, as measured by a pretest and posttest methodology when ensuring that the individual outcomes were not the result of group collaboration. This study employed a quantitative, quasi-experimental study design that used a comparison and experimental group. Inferential statistical analysis was employed. The study was conducted at a high school in southwest Colorado. Eighty-nine respondents returned completed and signed consent forms, and 78 participants completed the study. Results demonstrated that augmented reality instruction caused posttest scores to significantly increase, as compared to pretest scores, but it was not as effective as traditional classroom instruction. Scores did improve under both types of instruction; therefore, more research is needed in this area. The present study was the first quantitative experiment controlling for individual learning to validate augmented reality using mobile handheld digital devices that affected individual students' learning outcomes without group collaboration. This topic was important to the field of education as it may help educators understand how students learn and it may also change the way students are taught.

    Clay modeling is increasingly used as a teaching method other than dissection. The haptic experience during clay modeling is supposed to correspond to the learning effect of manipulations during exercises in the dissection room involving tissues and organs. We questioned this assumption in two pretest-post-test experiments. In these experiments, the learning effects of clay modeling were compared to either live observations (Experiment I) or video observations (Experiment II) of the clay-modeling exercise. The effects of learning were measured with multiple choice questions, extended matching questions, and recognition of structures on illustrations of cross-sections. Analysis of covariance with pretest scores as the covariate was used to elaborate the results. Experiment I showed a significantly higher post-test score for the observers, whereas Experiment II showed a significantly higher post-test score for the clay modelers. This study shows that (1) students who perform clay-modeling exercises show less gain in anatomical knowledge than students who attentively observe the same exercise being carried out and (2) performing a clay-modeling exercise is better in anatomical knowledge gain compared to the study of a video of the recorded exercise. The most important learning effect seems to be the engagement in the exercise, focusing attention and stimulating time on task. © 2014 American Association of Anatomists.

    Full Text Available Objectives: Substance abuse is one of the most outstanding socio-psychological hazards that can easily wreck one’s personal, family and social life. Reality Therapy is a type of Cognitive rehabilitation (known as psychosocial rehabilitation, and the application of this method in the treatment of different disorders has recently been the topic of research. The objective of this study was to examine the effectiveness of group reality therapy on the reduction of stress, anxiety and depression in addicts. Methods: A quasi-experimental study of pretest-posttest design, with a control group was conducted. The study population consisted of all addicts attending Tehran’s ‘Neda’ Rehab Clinic. First, the DASS-21 questionnaire was administered and then 40 people were selected from those who had scored average and higher. They were then randomly assigned to two test and control groups of 20 each. Analysis of co-variance was used to analyze the data, with which pretest scores were controlled, and the effect of the independent variable on posttest scores was evaluated. Results: Following the intervention, there were significant decreases in the mean scores of all three variables, i.e. stress, anxiety and depression in the test group (P<0.05. Discussion: Psychosocial rehabilitation based on reality therapy can be considered as an effective method for reducing stress, anxiety and depression in addicts and also as an adjunctive therapy in treating other ailments.

    The aim of this study was to evaluate an infant oral health education programme, using a pre-post test design, for parents attending a paediatric clinic. The subjects were parents attending the well baby appointments at 3, 6, and 9 months of age. The study participants were men and women, all with an infant between 3 and 12 months of age. A 16 question assessment in the form of a questionnaire was completed immediately before and after the introduction of a 30 min educational intervention in the form of a PowerPoint presentation and a video of infant oral hygiene for parents. The parents completed the questionnaire twice (pre-post test design) in the same visit. Recruited parents attended only one presentation. The presentation educated parents about infant oral health and provided anticipatory guidance. Forty-seven parents or caretakers participated in the study. On the pre-test 28% had a score of 70% or less, and on the post-test 87% got a score of 88% or better. On the pre-test, 72% had a score of 70% or higher, and on the post-test 87% got a score of 88% or higher. Most parents (80%) reported that the presentation was helpful and indicated that the information would change the way they care for their baby's teeth at home. This study demonstrated the effectiveness of a 30 min PowerPoint and Video presentation in improving the oral health knowledge of parents caring for an infant.

    Full Text Available This study aimed to show whether administering a battery of time-series diagnostic tests (screening has any impact on Iranian EFL learners’ writing ability. The study was conducted on the intermediate EFL learners at Islamic Azad University North Tehran branch.  The researcher administered a homogenizing test in order to exclude the exceptional scores, among all the testers, only those whose scores were nearly within one standard deviation above or below the mean were selected as the participants of this study. After the assignment of the participants to the control and experimental groups- 30 students in each group- they were asked to write five-paragraph-essays on two topics. Such a pretest was given to both groups to test their initial writing ability. Once scoring of the students’ writings (five- paragraph essay was finished the two means of the groups were calculated and compared with each other through the t-test analysis. The result demonstrated that there was no statistically significant difference between those two groups regarding the variable under investigation. Four sets of diagnostic tests were given to the experimental group every two weeks and after each test both the result of the exam and suitable feedback regarding students’ errors were given to them by the teacher, while the Current-Traditional Rhetoric method was administered in the control group. In the posttest which was run after giving the treatment and placebo to experimental group and control group respectively, students took another writing test with the same characteristics in administration, topics and scoring as the one in pretest. Thereafter, the significance of the difference between the obtained means of experimental and control groups in the posttest was determined through the t-test.  The result of the t-test analysis indicated a significant difference between the two groups which consequently rejected the null hypothesis of the study.

MESA students also scored significantly lower than ATDP students on pre-test measures but both populations scored equally well on the post-tests. This dissertation has therefore shown the SIMALE to support a collaborative, reflective, and generative learning environment. Furthermore, the SIMALE clearly contributes to students' mechanical reasoning and understanding of simple machines concepts for a diverse population of students.

    Previously, we proposed a model for ordinal scale scoring in which individual thresholds for each item constitute a distribution by each item. This lead us to hypothesize that the boundary curves of each depressive symptom score in the distribution of total depressive symptom scores follow a common mathematical model, which is expressed as the product of the frequency of the total depressive symptom scores and the probability of the cumulative distribution function of each item threshold. To verify this hypothesis, we investigated the boundary curves of the distribution of total depressive symptom scores in a general population. Data collected from 21,040 subjects who had completed the Center for Epidemiologic Studies Depression Scale (CES-D) questionnaire as part of a national Japanese survey were analyzed. The CES-D consists of 20 items (16 negative items and four positive items). The boundary curves of adjacent item scores in the distribution of total depressive symptom scores for the 16 negative items were analyzed using log-normal scales and curve fitting. The boundary curves of adjacent item scores for a given symptom approximated a common linear pattern on a log normal scale. Curve fitting showed that an exponential fit had a markedly higher coefficient of determination than either linear or quadratic fits. With negative affect items, the gap between the total score curve and boundary curve continuously increased with increasing total depressive symptom scores on a log-normal scale, whereas the boundary curves of positive affect items, which are not considered manifest variables of the latent trait, did not exhibit such increases in this gap. The results of the present study support the hypothesis that the boundary curves of each depressive symptom score in the distribution of total depressive symptom scores commonly follow the predicted mathematical model, which was verified to approximate an exponential mathematical pattern.

    Full Text Available This research aims to find out whether Herringbone Technique can developEFL students’ reading comprehension or not, especially in finding the main idea and supporting details in a recount text. The literature notes that Herringbone is known to be one of the techniques that can helpstudents to find important information and main idea in a text by seeking for answers on six comprehension questions on a diagram, viewed such as a fish’s skeleton. The sample of this research was 30 second grade junior high school students. The researchers employed simple random sampling to choose the sample. It further used the quantitative experimental approach with the pre-experimental design in the form of one group pre-test-post-test design.Pre-test was given before treatments, while post-test was given after the students were taught reading by using the Herringbone Technique. Each pre-test and post-test consisted of ten questions. The statistical formulas were used to analyze the data from the students tests’ scores. The mean score of pre-test was 59 and the post-test was 76. Futhermore, the result of t-test was 10.15, while the critical value of 0.05 significant level was 2.045, with the degree of freedom of 29. Since t-test (10.15 was higher than t-table (2.045, this study concludes that this technique could increase the EFL students’ reading comprehension.Despite in practice the researchers found that this technique decreased the students’ efforts in note-taking, however it did not inhibited them in obtaining improved scores in their reading tests.

    Faculty development programs, studied both home and abroad, have been shown to be helpful for enhancing the scholarly and academic work of nonacademic clinicians. Interprofessional education and faculty development efforts have been less well studied. This project investigated the effect of a well-studied faculty development program applied in an interprofessional fashion across health profession educators in medicine and nursing. A faculty cohort of nurse and physician educators at The University of Tokyo underwent training in the Stanford Faculty Development Center (SFDC) model of clinical teaching through a sequence of 7 workshops. The workshops were performed in English with all materials translated into Japanese. A validated, retrospective pretest and posttest instrument was used to measure study outcomes on global assessment of teaching abilities and specific teaching behaviors (STBs) at 1 and 12 months after intervention. Successful completion of Commitment to Change statements were also assessed at 12 months. In total, 19 faculty participants completed the study. All participants found the workshops valuable. For global assessment, significant improvement in self-reported teaching abilities was seen comparing the mean pretest scores of 27.26 (maximum score = 55, standard deviation [SD] = 8.61) with mean scores at both 1 month (36.81, SD = 7.48, P Japan.

    We previously developed a comprehensive proficiency-based robotic training curriculum demonstrating construct, content, and face validity. This study aimed to assess reliability, feasibility, and educational benefit associated with curricular implementation. Over an 11-month period, 55 residents, fellows, and faculty (robotic novices) from general surgery, urology, and gynecology were enrolled in a 2-month curriculum: online didactics, half-day hands-on tutorial, and self-practice using nine inanimate exercises. Each trainee completed a questionnaire and performed a single proctored repetition of each task before (pretest) and after (post-test) training. Tasks were scored for time and errors using modified FLS metrics. For inter-rater reliability (IRR), three trainees were scored by two raters and analyzed using intraclass correlation coefficients (ICC). Data from eight experts were analyzed using ICC and Cronbach's α to determine test-retest reliability and internal consistency, respectively. Educational benefit was assessed by comparing baseline (pretest) and final (post-test) trainee performance; comparisons used Wilcoxon signed-rank test. Of the 55 trainees that pretested, 53 (96 %) completed all curricular components in 9-17 h and reached proficiency after completing an average of 72 ± 28 repetitions over 5 ± 1 h. Trainees indicated minimal prior robotic experience and "poor comfort" with robotic skills at baseline (1.8 ± 0.9) compared to final testing (3.1 ± 0.8, p reliability was 0.91 (p training for all nine tasks and according to composite scores (548 ± 176 vs. 914 ± 81, p reliability measures, demonstrated feasibility for a large cohort of trainees, and yielded significant educational benefit. Further studies and adoption of this curriculum are encouraged.

    About 10% of patients admitted to a chest pain unit (CPU) exhibit atrial fibrillation (AF). To determine whether calcium scores (CS) are superior over common risk scores for coronary artery disease (CAD) in patients presenting with atypical chest pain, newly diagnosed AF, and intermediate pretest probability for CAD within the CPU. In 73 subjects, CS was related to the following risk scores: Global Registry of Acute Coronary Events (GRACE) score, including a new model of a frequency-normalized approach; Thrombolysis In Myocardial Infarction score; European Society of Cardiology Systematic Coronary Risk Evaluation (SCORE); Framingham risk score; and Prospective Cardiovascular Münster Study score. Revascularization rates during index stay were assessed. Median CS was 77 (interquartile range, 1-270), with higher values in men and the left anterior descending artery. Only the modified GRACE (ρ = 0.27; P = 0.02) and the SCORE (ρ = 0.39; P risk scores and calcium burden, as well as revascularization rates during index stay, were low. By contrast, the determination of CS may be used as an additional surrogate marker in risk stratification in AF patients with intermediate pretest likelihood for CAD admitted to a CPU. © 2016 Wiley Periodicals, Inc.

    Objective. To design and evaluate the integration of a virtual patient activity in a required therapeutics course already using a flipped-classroom teaching format. Design. A narrative-branched, dynamic virtual-patient case was designed to replace the static written cases that students worked through during the class, which was dedicated to teaching the complications of liver disease. Students completed pre- and posttests before and after completing the virtual patient case. Examination scores were compared to those in the previous year. Assessment. Students’ posttest scores were higher compared to pretest scores (33% vs 50%). Overall median examination scores were higher compared to the historical control group (70% vs 80%), as well as scores on questions assessing higher-level learning (67% vs 83%). A majority of students (68%) felt the virtual patient helped them apply knowledge gained in the pre-class video lecture. Students preferred this strategy to usual in-class activities (33%) or indicated it was of equal value (37%). Conclusion. The combination of a pre-class video lecture with an in-class virtual patient case is an effective active-learning strategy. PMID:28179724

    Shapiro, Marina

    A quasi-experimental design pre-test/post-test intervention study utilizing a within group analysis was conducted with 45 undergraduate college chemistry students that investigated the effect of implementing a game-based learning environment into an undergraduate college chemistry course in order to learn if serious educational games (SEGs) can be used to achieve knowledge gains of complex chemistry concepts and to achieve increase in students' positive attitude toward chemistry. To evaluate if students learn chemistry concepts by participating in a chemistry game-based learning environment, a one-way repeated measures analysis of variance (ANOVA) was conducted across three time points (pre-test, post-test, delayed post-test which were chemistry content exams). Results showed that there was an increase in exam scores over time. The results of the ANOVA indicated a statistically significant time effect. To evaluate if students' attitude towards chemistry increased as a result of participating in a chemistry game-based learning environment a paired samples t-test was conducted using a chemistry attitudinal survey by Mahdi (2014) as the pre- and post-test. Results of the paired-samples t-test indicated that there was no significant difference in pre-attitudinal scores and post-attitudinal scores.

    This study sought to create a contemporary scoring tool to predict technical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) from patients treated by hybrid operators with differing experience levels. Current scoring systems need regular updating to cope with the positive evolutions regarding materials, techniques, and outcomes, while at the same time being applicable for a broad range of operators. Clinical and angiographic characteristics from 880 CTO-PCIs included in the REgistry of CrossBoss and Hybrid procedures in FrAnce, the NetheRlands, BelGium and UnitEd Kingdom (RECHARGE) were analyzed by using a derivation and validation set (2:1 ratio). Variables significantly associated with technical failure in the multivariable analysis were incorporated in the score. Subsequently, the discriminatory capacity was assessed and the validation set was used to compare with the J-CTO score and PROGRESS scores. Technical success in the derivation and validation sets was 83% and 85%, respectively. Multivariate analysis identified six parameters associated with technical failure: blunt stump (beta coefficient (b) = 1.014); calcification (b = 0.908); tortuosity ≥45° (b = 0.964); lesion length 20 mm (b = 0.556); diseased distal landing zone (b = 0.794), and previous bypass graft on CTO vessel (b = 0.833). Score variables remained significant after bootstrapping. The RECHARGE score showed better discriminatory capacity in both sets (area-under-the-curve (AUC) = 0.783 and 0.711), compared to the J-CTO (AUC = 0.676) and PROGRESS (AUC = 0.608) scores. The RECHARGE score is a novel, easy-to-use tool for assessing the risk for technical failure in hybrid CTO-PCI and has the potential to perform well for a broad community of operators. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Interprofessional education is intended to train practitioners to collaboratively address challenges in healthcare delivery, and interprofessional simulation-based education (IPSE) provides realistic, contextual learning experiences in which roles, responsibilities, and professional identity can be learned, developed, and assessed. Reducing negative stereotypes within interprofessional relationships is a prime target for IPSE. We sought to understand whether perceptions of interprofessional education and provider stereotypes change among nursing and medical students after participating in IPSE. We also sought to determine whether changes differed based on the student's discipline. This was a quasi-experimental pretest-posttest study. The study took place at a large mid-Atlantic public university with a comprehensive health science campus. 147 senior Bachelors of Science in Nursing students and 163 fourth-year medical students participated. Students were grouped into interprofessional teams for a two-week period and participated in three two-hour simulations focused on collaboration around acutely ill patients. At the beginning of the first session, they completed a pretest survey with demographic items and measures of their perceptions of interprofessional clinical education, stereotypes about doctors, and stereotypes about nurses. They completed a posttest with the same measures after the third session. 251 students completed both the pretest and posttest surveys. On all three measures, students showed an overall increase in scores after the IPSE experience. In comparing the change by student discipline, medical students showed little change from pretest to posttest on stereotypes of doctors, while nursing students had a significant increase in positive perceptions about doctors. No differences were noted between disciplines on changes in stereotypes of nurses. This study demonstrated that a short series of IPSE experiences resulted in improved perceptions of

    The study examined the influence of training on first-year nursing department students' attitudes on death and caring for dying patients. Utilizing the experimental model, the study sample consisted of 81 first-year students attending the nursing department of a university. Death Attitude Profile-Revised and Frommelt Attitude toward Care of the Dying Scale were used for data collection. Data analysis included means, standard deviation, and t test for related samples. Student attitudes toward death were measured as 146.43 (16.741) and 152.75 (15.132) for pre- and posttraining, respectively. Student attitudes toward caring for dying patients were established to be 103.02 (7.655) during pretraining period and 111.02 (10.359) at posttraining period. The difference between pre- and posttests for mean attitudes toward death and caring for the dying patient was statistically significant. Study results determined that training was effective in forming positive student attitudes toward death and caring for dying patients.

    Full Text Available OBJECTIVES: Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS: A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B. Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post- were analyzed by two pediatric pulmonologists. RESULTS: Of the 66 professionals, 87.9% were females. Of a total possible score of ten, the mean score obtained in the pre-test was 5.3 ± 3, and in the second test, 7.5 ± 2 (p < 0.000. There were no significant differences when comparing the two groups (p = 0.726. The nurses had the lowest mean scores in the initial test (2.3 ± 2; however, they were the group that learned the most with the intervention, showing similar means to those of other groups in the second test (6.1 ± 3. CONCLUSION: There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods, demonstrating that education, when available to professionals, positively modifies medical practice.

    The aim of this study was to determine the effectiveness of an assertive training for school-aged children on peer bullying and assertiveness. A quasi-experimental design using pre- and post-testing was conducted. Data were collected using a demographic questionnaire, an assertiveness scale, and the peer victimization scale. The training program was comprised of eight sessions which were implemented to intervention group. Descriptive characteristics were not statistically different between the groups (p>0.05). The peer victimization victim dimension results show that post-test mean scores of the students in the intervention group were lower than the pre-test mean scores (p0.05). A comparison of the mean pre-test/post-test scores of peer-victimization bully dimension of the students' intervention and control groups revealed that the mean post-test scores of the students in the each group decreased (p>0.05). An assertiveness training program increased the assertiveness level and reduced the state of being victims, but did not affect the state of being bullies. The results of this study can help children acquire assertive behaviors instead of negative behaviors such as aggression and shyness, and help them to build effective social communication.

    Full Text Available Recovery following facial nerve palsy is variable. Physiotherapists try  to restore  function  in  patients  with  Bell’s  palsy.  The  choice  of treatment modality  depends  on  the  stage  of  the  condition.  Although limited  evidence  exists  for  the  use  of  electrical  stimulation  in  the acute  stage  of  Bell’s  palsy, some physiotherapists in South Africa have been applying this modality. This study examined the effects of electrical stimulation on functional recovery from  Bell’s palsy using the Facial Disability Index, a tool that documents recovery from the patients’ perspective. A two group pre-test post-test experimental design comprising of 16 patients with Bell’s Palsy of less than 30 days duration was utilized. Patients with a clinical diagnosis of Bell’s Palsy were systematically allocated to the control and experimental groups. Patients (n=16 were pre-tested and post-tested using the Facial Disability Index. Both groups were treated with heat, massage, exercises and given a home program. The experimental group also received electrical stimulation. The FDI of the control group improved between 17, 8% and 95, 4% with a mean of 52, 8%. The improvement in the experimental group ranged between 14, 8% and 126% with a mean of 49, 8%. Certain clinical residuals persisted in a mild form in both groups on discharge from the study.  The effects of electrical stimulation as used in this study during the acute phase of Bell’s palsy, quantified as the FDI was clinically but not statistically significant. A larger sample size, longer stimulation time or both should be investigated.

    Bystander cardiopulmonary resuscitation improves survival after out-of-hospital cardiac arrest. This study aimed to assess the effectiveness of a basic life support (BLS) educational course given to 110 middle school children, using a pretest posttest design. In the pretest, students were asked to demonstrate BLS on a manikin to simulate a real-life scenario. After the pretest, a BLS training course of two sessions was provided, followed by posttest on the same manikin. Students were assessed using an observational sheet based on the American Heart Association's BLS guidelines. In the pretest, students showed significant weakness in the majority of guidelines. In the posttest, they demonstrated significant improvement in their BLS skills. BLS training in the middle school was effective, considering the lack of previous skills. It is recommended that BLS education be compulsory in the school setting.

    In nursing education, the inclusion of pedagogical tools is necessary to transform Millennial classrooms. One such pedagogical tool currently offered is classroom response systems (CRS). The purpose of this study was to evaluate the effectiveness of CRS as a pedagogical tool in improving nursing students' examination performance within an active learning environment. A pretest-posttest design was used to determine whether there was a relationship between the use of CRS (independent variable) and nursing students' examination performance in a first-year Professional Practice course (dependent variable). Paired t tests revealed no greater improvement in posttest scores. Therefore, the use of CRS technology was not effective in increasing nursing students' examination scores in the Professional Practice course. Additional research is needed to provide adequate understanding of the effectiveness of CRS within the nursing education classroom. Copyright 2013, SLACK Incorporated.

    Guatemala's Maternal Mortality Rate is 65th highest in the world at 120 deaths per 100,000 births. Contributing to the problem is traditional birth attendants (TBAs) attend most births yet lack knowledge about obstetrical emergencies. Government trainings in existence since 1955 have not changed TBA knowledge. Government trainings are culturally insensitive because they are taught in Spanish with written material, even though most TBAs are illiterate and speak Mayan dialects. The purpose of the observational study was to evaluate the effect of an oral training, that was designed to be culturally sensitive in TBAs' native language, on TBAs' knowledge of obstetrical emergencies. one hundred ninety-one TBAs participated. The study employed a pretest-posttest design. A checklist was used to compare TBAs' knowledge of obstetrical emergencies before and after the training. the mean pretest score was 5.006±SD 0.291 compared to the mean posttest score of 8.549±SD 0.201. Change in knowledge was a P value of 0.00. results suggest an oral training that was designed to be culturally sensitive in the native language improved TBAs' knowledge of obstetrical emergencies. Future trainings should follow a similar format to meet the needs of illiterate audiences in remote settings. Copyright © 2018 Elsevier Ltd. All rights reserved.

Quasi-experimental control group interrupted time series design was employed. Data pertaining to these variables were collected from 369 students and 18 biology teachers in three schools. A series of biological tests and semistructured questionnaire were used to collect data. Multivariate analysis (two-way ANOVA was used to analyze the test scores exposed by teaching methods, and semistructured questionnaire was administered to comprehend factors that hamper the successive execution of CL. Hence, multivariate analysis revealed that there was no significant (P>0.05 difference in the pretest score of the learner academic performance; however, there were significant differences (P<0.01 in the posttest results by teaching methods, but not by schools. Correspondingly, there were significant differences in the pretest P<0.05 and posttest (P<0.01 results of the students’ laboratory proficiency by teaching methods. The results exemplify that there was significant learning gain obtained via CLAD followed by cooperative discussion group (CDG. The result from the questionnaire survey showed that the number of students, lack of laboratory equipment, and so on hamper consecutive execution of CL.

    The teaching and learning of games and sport-based activities has historically been the dominant form of the physical education curricula. With an interest in providing to students meaningful and culturally situated sporting experiences, Sport Education is probably the most implemented and researched pedagogical model worldwide. However, although there is considerable evidence that the model as a curriculum approach can benefit the development of social goals and healthy sport behaviors, not a single study as to date examined students’ game-play development beyond participation in single and isolated teaching units. Therefore, the purpose of this study was to examine students’ development of Game Performance and Game Involvement during participation in three consecutive Sport Education seasons of invasion games. The participants were an experienced physical education teacher and one seventh-grade class totaling 26 students (10 girls and 16 boys). Using the Game Performance Assessment Instrument (Oslin et al., 1998), pre-test to post-tests measures of students’ Game Performance and Game Involvement were collected during their participation in basketball (20 lessons), handball (16 lessons), and football (18 lessons) units. Inter-group differences and pre-test to post-test improvements within each season were analyzed through 2 (time) x group (sport) repeated measures ANOVA tests. There were found significant pre-test to post-test improvements in Game Performance and Game Involvement in the second (handball) and third (football) seasons, but not in the first season (basketball). Students’ Game Performance and Involvement scores of handball and football were significantly higher than their scores while playing basketball. The opportunity for an extended engagement in game-play activities and prolonged membership of students in the same teams throughout three consecutive seasons of Sport Education were key to the outcomes found.

    To evaluate a tele-education system developed to improve diagnostic competency in retinopathy of prematurity (ROP) by ophthalmologists-in-training in Mexico. Prospective, randomized cohort study. Fifty-eight ophthalmology residents and fellows from a training program in Mexico consented to participate. Twenty-nine of 58 trainees (50%) were randomized to the educational intervention (pretest, ROP tutorial, ROP educational chapters, and posttest), and 29 of 58 trainees (50%) were randomized to a control group (pretest and posttest only). A secure web-based educational system was created using clinical cases (20 pretest, 20 posttest, and 25 training chapter-based) developed from a repository of over 2500 unique image sets of ROP. For each image set used, a reference standard ROP diagnosis was established by combining the clinical diagnosis by indirect ophthalmoscope examination and image-based diagnosis by multiple experts. Trainees were presented with image-based clinical cases of ROP during a pretest, posttest, and training chapters. The accuracy of ROP diagnosis (e.g., plus disease, zone, stage, category) was determined using sensitivity and specificity calculations from the pretest and posttest results of the educational intervention group versus control group. The unweighted kappa statistic was used to analyze the intragrader agreement for ROP diagnosis by the ophthalmologists-in-training during the pretest and posttest for both groups. Trainees completing the tele-education system had statistically significant improvements (P education system performed better on the posttest for accurately diagnosing plus disease (67% vs. 48%; P = 0.04) and the presence of ROP (96% vs. 91%; P education system compared with the control group. Intragrader agreement improved for identification of plus disease, zone, stage, and category of ROP after completion of the educational intervention. A tele-education system for ROP education was effective in improving the diagnostic

    To investigate whether a comprehensive exercise program was effective in improving physical function among institutionalized older adults and whether adding whole-body vibration to the program conferred additional therapeutic benefits. A single-blinded randomized controlled trial was conducted. This study was carried out in residential care units. In total, 73 older adults (40 women, mean age: 82.3 ± 7.3 years) were enrolled into this study. Participants were randomly allocated to one of the three groups: strength and balance program combined with whole-body vibration, strength and balance program without whole-body vibration, and social and recreational activities consisting of upper limb exercises only. All participants completed three training sessions per week for eight weeks. Assessment of mobility, balance, lower limb strength, walking endurance, and self-perceived balance confidence were conducted at baseline and immediately after the eight-week intervention. Incidences of falls requiring medical attention were recorded for one year after the end of the training period. A significant time × group interaction was found for lower limb strength (five-times-sit-to-stand test; P = 0.048), with the exercise-only group showing improvement (pretest: 35.8 ± 16.1 seconds; posttest: 29.0 ± 9.8 seconds), compared with a decline in strength among controls (pretest: 27.1 ± 10.4 seconds; posttest: 28.7 ± 12.3 seconds; P = 0.030). The exercise with whole-body vibration group had a significantly better outcome in balance confidence (pretest: 39.2 ± 29.0; posttest: 48.4 ± 30.6) than the exercise-only group (pretest: 35.9 ± 24.8; posttest: 38.2 ± 26.5; P = 0.033). The exercise program was effective in improving lower limb strength among institutionalized older adults but adding whole-body vibration did not enhance its effect. Whole-body vibration may improve balance confidence without enhancing actual balance performance.

    Full Text Available Objectives: Hypertension is a major risk factor for white matter hyperintensities, lacunes, cerebral microbleeds and perivascular spaces, which are MRI markers of cerebral small vessel disease (SVD. Studies have shown associations between these individual MRI markers and cognitive functioning and decline. Recently, a total SVD score was proposed in which the different MRI markers were combined into one measure of SVD, to capture total SVD-related brain damage. We investigated if this SVD score was associated with cognitive decline over 4 years in patients with hypertension. Methods: In this longitudinal cohort study, 130 hypertensive patients (91 patients with uncomplicated hypertension and 39 hypertensive patients with a lacunar stroke were included. They underwent a neuropsychological assessment at baseline and after 4 years. The presence of white matter hyperintensities, lacunes, cerebral microbleeds, and perivascular spaces were rated on baseline MRI. Presence of each individual marker was added to calculate the total SVD score (range 0-4 in each patient. Results: Uncorrected linear regression analyses showed associations between SVD score and decline in overall cognition (p=0.017, executive functioning (p<0.001 and information processing speed (p=0.037, but not with memory (p=0.911. The association between SVD score and decline in overall cognition and executive function remained significant after adjustment for age, sex, education, anxiety and depression score, potential vascular risk factors, patient group and baseline cognitive performance.Conclusions: Our study shows that a total SVD score can predict cognitive decline, specifically in executive function, over 4 years in hypertensive patients. This emphasizes the importance of considering total brain damage due to SVD.

    In this study, we assessed whether an intervention designed to improve children's sibling relationships, the More Fun with Sisters and Brothers program (MFWSB), may also help parents manage their emotions more effectively. Families with at least 2 children between the ages of 4 and 8 years were randomly assigned to an intervention (n = 50) or wait-list control (n = 34) group. Parents completed pre- and posttest questionnaires on sibling warmth and agonism, their emotion regulation during sibling conflict, and their global emotion regulation styles. Program participation had a direct effect on 3 of the 4 emotion regulation outcomes for mothers. Mothers in the intervention versus control group reported lower levels of dysregulation and suppression and higher levels of reappraisal at posttest, controlling for pretest regulation scores. Additionally, path models examining posttest responses showed that participation in MFWSB led to lower levels of maternal and paternal negative reactivity in the sibling context via lower levels of sibling agonism, controlling for pretest levels of negative reactivity. Alternate path models, with parents' emotion regulation as mechanisms linking MFWSB and sibling relationship quality, were tested but not supported. Results highlight the value of a sibling-focused intervention for promoting parents' abilities to regulate their emotions. (c) 2015 APA, all rights reserved).

    A training program for apheresis nurses in leukocyte collection and therapeutic apheresis was developed by the Joint Task Force for Apheresis Education and Certification. This is a modular program with theoretical and practical information and knowledge. On request of the Indonesian authorities, in the capital of Indonesia Jakarta, a certification course for apheresis nurses/operators based on the training program described above was organized in December 2013. The course existed of themes related to apheresis, such as hematology, anatomy, physiology, calculations, adverse events, basics of apheresis, nursing aspects, quality, collection of cells for cellular therapies, pediatrics, and therapeutic collections (cell reductions and exchange procedures). A pretest and post-test regarding the knowledge and judgment in the themes described was taken in Bahasa Indonesia or in English. In total, 38 apheresis nurses and 32 physicians participated in the course. In the post-test, the nurses scored in a mean 72/100 and the physicians 77/100 (nurses vs. physicians: P = 0.005), which was significantly better than the results of the pretest (54/100 and 53/100, respectively (P nurses/operators proved a significant increase of knowledge in the theory behind apheresis. This educational program provides an approach to educate and certificate apheresis nurses. It is also shown that also for physicians working in the field of apheresis, this course is of use increasing their knowledge regarding apheresis. © 2014 Wiley Periodicals, Inc.

    Dental hygiene educators must determine which educational practices best promote critical thinking, a quality necessary to translate knowledge into sound clinical decision making. The aim of this small pilot study was to determine whether virtual patient simulation had an effect on the critical thinking of dental hygiene students. A pretest-posttest design using the Health Science Reasoning Test was used to evaluate the critical thinking skills of senior dental hygiene students at The University of Texas School of Dentistry at Houston Dental Hygiene Program before and after their experience with computer-based patient simulation cases. Additional survey questions sought to identify the students' perceptions of whether the experience had helped develop their critical thinking skills and improved their ability to provide competent patient care. A convenience sample of 31 senior dental hygiene students completed both the pretest and posttest (81.5% of total students in that class); 30 senior dental hygiene students completed the survey on perceptions of the simulation (78.9% response rate). Although the results did not show a significant increase in mean scores, the students reported feeling that the use of virtual patients was an effective teaching method to promote critical thinking, problem-solving, and confidence in the clinical realm. The results of this pilot study may have implications to support the use of virtual patient simulations in dental hygiene education. Future research could include a larger controlled study to validate findings from this study.

  15. Using Robots to Motivate At-Risk Learners in Science over the Ninth Grade Hurdle

    Cerge, Dora

    The ninth grade is a pivotal year in an adolescent's academic career; however, educators have failed to find a remedy for the high failure and dropout rates at this grade level. Students who lack basic skills and support as they enter high school can experience repeated failures, which often lead to a decrease in motivation and dropping out of school. Up to 15% of all ninth graders repeat ninth grade and 36% of all U. S. dropouts are ninth graders. It is imperative that researchers and educators find new ways to motivate at-risk students and augment basic skills in order to mitigate the dropout problem at this grade level. Robot teachers could be a viable solution to increase student motivation and achievement. However, before such strategies could be recommended for implementation, information about their efficacy in a high school setting is needed. The purpose of this quantitative, two-group experimental, pretest-posttest study was to determine the effects of a robot teacher/instructor on science motivation and science achievement in ninth grade at-risk learners. Approximately 40 at-risk, repeating ninth graders, ranging in age from 13 to 17 years old from one high school in the United States Virgin Islands, participated in the study. Half of the students received a robot teacher/instructor manipulation whereby a robot taught a science lesson for physical science assessments (experimental group), and the other half received the same instruction from a human teacher (control group). An analysis of covariance (ANCOVA) was used to compare the science achievement posttest scores, as measured by test scores, and science motivation posttest scores, as measured by the SMTSL, between the experimental and the control groups, while controlling for the pretest scores (covariate). The results demonstrated that posttest motivation and achievement scores in the human teacher condition were not significantly different than posttest motivation scores in the robot teacher

    The astronomy lab at the University of Maine consists of discrete weekly lessons in which students work in small groups. Individual pretests and post-tests accompany each lesson. The lesson studied here covers the topic of time, including sidereal time, Apparent Solar Time, and time zones. The pretest consists of four multiple-choice questions, which are also administered after instruction as a post-test. In the fall 2004 semester, the pretest was rewritten to focus on some major conceptual components of the lab, while the lesson materials were not modified from previous years. Examination of class performance (n = 96) revealed no significant improvements in score from pre- to post-lesson. In the spring 2005 semester, the lesson was altered to incorporate the Starry Night software for simulating the sky instead of the celestial sphere models previously used. The goal of the change was to give students a more interactive environment for completing the laboratory exercise, which was otherwise altered as little as possible. Data from the spring semester show some gains on the pre/post-test questions covering sidereal time and Daylight Savings Time. Results to date have informed planned modifications to the lesson. A. L. T. was supported during this research by the University of Maine through a Provost Fellowship.

    Quantitative and qualitative methodologies were combined to explore the relationships between an understanding of evolution and 4 epistemology factors: (a) control of learning, (b) speed of learning , (c) stability of knowledge, and (d) belief in evolution/creationism. A 17-item instrument was developed that reliably measured a belief in creationism and subtle differences between this belief and an acceptance of evolution. The subjects were 45 students enrolled in a biology course at a 2-year community college. Evolution was taught in a traditional format, and common descent was taught in an inquiry-based laboratory session consisting of: (a) a comparison of hemoglobin DNA sequences of the human, chimpanzee, and gorilla; and (b) a comparison of 8 primate skull casts, including the modern human, chimpanzee, gorilla, and five prehistoric fossils. Prior to instruction the students completed an epistemology questionnaire and a knowledge test about evolution. Five weeks after instruction, the students completed a posttest. A t-test revealed no differences between the pretest and the posttest. However, the group of students that scored higher on the posttest than on the pretest was found to have a stronger belief in the uncertainty of knowledge. Pearson r was computed to check for relationships between the 4 epistemological factors and the understanding of evolution. There was a significant relationship between a belief in creationism and a lessor understanding of evolution as measured on both the pretest and the posttest (ps humans evolved from the chimpanzee. Additionally, students grouped the 8 primate skulls into just 2 categories: human and animals. Other misconceptions included a nonevolutionary use of the term, related, and the use of naive organizers leading to incorrect conclusions about the relatedness of certain organisms, such as a connection between fish and whales. These organizers included: (a) similarity of traits, (b) environment, (c) relative size, (d

    The profound impact of empathy training on quality nursing care has been recognized. Studies have shown that there has been little improvement in nurses' communication skills, and that they should work to enhance this area. Relevant training will lead to an improvement in nurses' empathic skills, which in turn, will enable them to understand their patients better, establish positive interpersonal relationships with them, and boost their professional satisfaction. To reveal the effect of empathy training on the empathic skills of nurses. This study was conducted as an experimental design. The research sample consisted of 48 nurses working at the pediatric clinics of Farabi hospital of Karadeniz Technical University in Turkey (N = 83). Two groups, an experimental group (group 1) and a control group (group 2) were determined after questionnaires were supplied to all nurses in the study sample. At first, it was intended to select these groups using a random method. However, since this may have meant that the experimental and control groups were formed from nurses working in the same service, the two groups were selected from different services to avoid possible interaction between them. The nurses in the Group 1 were provided with empathy training through group and creative drama techniques. Pre-tests and post-tests were conducted on both groups. Data was collected via a questionnaire designed around the topic "empathic skill scale-ESS", developed by Dokmen. The Kolmogorov Smirnov test was employed to assess whether the measurable data was suitable for normal distribution. Data was presented as numbers and percentage distributions, as mean ± standard deviation and Chi-square, and as student t tests and paired t tests. The level of significance was accepted as P nurses in the experimental group had a mean score of 146.7 ± 38.8 and 169.5 ± 22.1 in the ESS pre-test and post-test, respectively. Although the nurses in the control group had a pre-test mean score of 133

    To evaluate the effects of 10 weeks of aerobic exercise on depressive and anxiety symptoms and self-esteem of breast cancer survivors. Experimental, crossover. Midwestern university town. Twenty-four breast cancer survivors (mean time following surgery 41.8 months; ranging from 1 to 99 months) recruited via mail and cancer support groups. The mean age of the sample was 48.9 years. Subjects were assigned randomly into exercise (EX), exercise-plus-behavior modification (EX + BM), and control groups. EX and EX + BM groups exercised aerobically four days/week at > or = 60% of age-predicted maximum heart rate for 10 weeks. Data were collected pretest, post-test, and crossover (12 weeks following post-test). Because pretest or post-test scores showed no statistical differences between EX and EX + BM groups, data were combined to form one group. Aerobic exercise (four days/ week; 30-40 minutes/session), depression, (Beck Depression inventory), anxiety (Speilberger State-Trait Anxiety Inventory), and self-esteem (Rosenberg Self-Esteem Inventory). Pre- to post-test analyses revealed that women who exercised had significantly less depression and state and trait anxiety over time compared to controls. After the crossover, the control group demonstrated comparable improvements in both depressive and state anxiety scores. Self-esteem did not change significantly. Subjects who received exercise recommendations from their physicians exercised significantly more than subjects who received no recommendation. Mild to moderate aerobic exercise may be of therapeutic value to breast cancer survivors with respect to depressive and anxiety symptoms but not to self-esteem. A physician's recommendation to exercise appears to be an important factor in a patient's exercise adherence. To Improve depressive and anxiety symptoms following breast cancer surgery, healthcare professionals should consider recommending mild to moderate exercise.

    Full Text Available We review the literature on the gender gap on concept inventories in physics. Across studies of the most commonly used mechanics concept inventories, the Force Concept Inventory and Force and Motion Conceptual Evaluation, men’s average pretest scores are always higher than women’s, and in most cases men’s posttest scores are higher as well. The weighted average gender difference on these tests is 13% for pretest scores, 12% for posttest scores, and 6% for normalized gain. This difference is much smaller than the average difference in normalized gain between traditional lecture and interactive engagement (25%, but it is large enough that it could impact the results of studies comparing the effectiveness of different teaching methods. There is sometimes a gender gap on commonly used electricity and magnetism concept inventories, the Brief Electricity and Magnetism Assessment and Conceptual Survey of Electricity and Magnetism, but it is usually much smaller and sometimes is zero or favors women. The weighted average gender difference on these tests is 3.7% for pretest scores, 8.5% for posttest scores, and 6% for normalized gain. There are far fewer studies of the gender gap on electricity and magnetism concept inventories and much more variation in the existing studies. Based on our analysis of 26 published articles comparing the impact of 30 factors that could potentially influence the gender gap, no single factor is sufficient to explain the gap. Several high-profile studies that have claimed to account for or reduce the gender gap have failed to be replicated in subsequent studies, suggesting that isolated claims of explanations of the gender gap should be interpreted with caution. For example, claims that the gender gap could be eliminated through interactive engagement teaching methods or through a “values affirmation writing exercise” were not supported by subsequent studies.

    Full Text Available Recent studies suggest that practice with approximate and non-symbolic arithmetic problems improves the math performance of adults, school aged children, and preschoolers. However, the relative effectiveness of approximate arithmetic training compared to available educational games, and the type of math skills that approximate arithmetic targets are unknown. The present study was designed to (1 compare the effectiveness of approximate arithmetic training to two commercially available numeral and letter identification tablet applications and (2 to examine the specific type of math skills that benefit from approximate arithmetic training. Preschool children (n = 158 were pseudo-randomly assigned to one of three conditions: approximate arithmetic, letter identification, or numeral identification. All children were trained for 10 short sessions and given pre and post tests of informal and formal math, executive function, short term memory, vocabulary, alphabet knowledge, and number word knowledge. We found a significant interaction between initial math performance and training condition, such that children with low pretest math performance benefited from approximate arithmetic training, and children with high pretest math performance benefited from symbol identification training. This effect was restricted to informal, and not formal, math problems. There were also effects of gender, socio-economic status, and age on post-test informal math score after intervention. A median split on pretest math ability indicated that children in the low half of math scores in the approximate arithmetic training condition performed significantly better than children in the letter identification training condition on post-test informal math problems when controlling for pretest, age, gender, and socio-economic status. Our results support the conclusion that approximate arithmetic training may be especially effective for children with low math skills, and that

We found a significant interaction between initial math performance and training condition, such that children with low pretest math performance benefited from approximate arithmetic training, and children with high pretest math performance benefited from symbol identification training. This effect was restricted to informal, and not formal, math problems. There were also effects of gender, socio-economic status, and age on post-test informal math score after intervention. A median split on pretest math ability indicated that children in the low half of math scores in the approximate arithmetic training condition performed significantly better than children in the letter identification training condition on post-test informal math problems when controlling for pretest, age, gender, and socio-economic status. Our results support the conclusion that approximate arithmetic training may be especially effective for children with low math skills, and that approximate arithmetic

    The main aim of the present study is to investigate the short-term cognitive effects of computer games in children with different psychiatric disorders and normal controls. One hundred one children are recruited for the study (aged between 9 and 12 years). All participants played a motor-racing game on the computer for 1 hour. The TBAG form of the Stroop task was administered to all participants twice, before playing and immediately after playing the game. Participants with improved posttest scores, compared to their pretest scores, used the computer on average 0.67 +/- 1.1 hr/day, while the average administered was measured at 1.6 +/- 1.4 hr/day and 1.3 +/- 0.9 hr/day computer use for participants with worse or unaltered scores, respectively. According to the regression model, male gender, younger ages, duration of daily computer use, and ADHD inattention type were found to be independent risk factors for worsened posttest scores. Time spent playing computer games can exert a short-term effect on attention as measured by the Stroop test.

    This study aimed to examine the efficacy and maintenance of short-term (one-session) gated audiovisual speech training for improving auditory sentence identification in noise in experienced elderly hearing-aid users. Twenty-five hearing aid users (16 men and 9 women), with an average age of 70.8 years, were randomly divided into an experimental (audiovisual training, n = 14) and a control (auditory training, n = 11) group. Participants underwent gated speech identification tasks comprising Swedish consonants and words presented at 65 dB sound pressure level with a 0 dB signal-to-noise ratio (steady-state broadband noise), in audiovisual or auditory-only training conditions. The Hearing-in-Noise Test was employed to measure participants’ auditory sentence identification in noise before the training (pre-test), promptly after training (post-test), and 1 month after training (one-month follow-up). The results showed that audiovisual training improved auditory sentence identification in noise promptly after the training (post-test vs. pre-test scores); furthermore, this improvement was maintained 1 month after the training (one-month follow-up vs. pre-test scores). Such improvement was not observed in the control group, neither promptly after the training nor at the one-month follow-up. However, no significant between-groups difference nor an interaction between groups and session was observed. Conclusion: Audiovisual training may be considered in aural rehabilitation of hearing aid users to improve listening capabilities in noisy conditions. However, the lack of a significant between-groups effect (audiovisual vs. auditory) or an interaction between group and session calls for further research. PMID:28348542

    Patient-reported outcome measures (PROMs) have become a cornerstone for the evaluation of the effectiveness of treatment. The Achilles tendon Total Rupture Score (ATRS) is a PROM for outcome and assessment of an Achilles tendon rupture. The aim of this study was to translate the ATRS to Dutch and evaluate its reliability and validity in the Dutch population. A forward-backward translation procedure was performed according to the guidelines of cross-cultural adaptation process. The Dutch ATRS was evaluated for reliability and validity in patients treated for a total Achilles tendon rupture from 1 January 2012 to 31 December 2014 in one teaching hospital and one academic hospital. Reliability was assessed by the intraclass correlation coefficients (ICC), Cronbach's alpha and minimal detectable change (MDC). We assessed construct validity by calculation of Spearman's rho correlation coefficient with domains of the Foot and Ankle Outcome Score (FAOS), Victorian Institute of Sports Assessment-Achilles questionnaire (VISA-A) and Numeric Rating Scale (NRS) for pain in rest and during running. The Dutch ATRS had a good test-retest reliability (ICC = 0.852) and a high internal consistency (Cronbach's alpha = 0.96). MDC was 30.2 at individual level and 3.5 at group level. Construct validity was supported by 75 % of the hypothesized correlations. The Dutch ATRS had a strong correlation with NRS for pain during running (r = -0.746) and all the five subscales of the Dutch FAOS (r = 0.724-0.867). There was a moderate correlation with the VISA-A-NL (r = 0.691) and NRS for pain in rest (r = -0.580). The Dutch ATRS shows an adequate reliability and validity and can be used in the Dutch population for measuring the outcome of treatment of a total Achilles tendon rupture and for research purposes.

    Stimulus equivalence procedures have been used to teach course material in higher education in the laboratory and in the classroom. The current study was a systematic replication of Walker, Rehfeldt, and Ninness (2010), who used a stimulus equivalence procedure to train information pertaining to 12 disorders. Specifically, we conducted (a) a written posttest immediately after each training unit and (b) booster training sessions for poor performers. Results showed immediate improvement from pretest to posttest scores after training, but problems with maintenance were noted in the final examination. Implications of poor maintenance are discussed in the context of the current study and stimulus equivalence research in higher education generally. © Society for the Experimental Analysis of Behavior.

  11. The effects of using screencasting as a multimedia pre-training tool to manage the intrinsic cognitive load of chemical equilibrium instruction for advanced high school chemistry students

    Chemistry is a complex knowledge domain. Specifically, research notes that Chemical Equilibrium presents greater cognitive challenges than other topics in chemistry. Cognitive Load Theory describes the impact a subject, and the learning environment, have on working memory. Intrinsic load is the facet of Cognitive Load Theory that explains the complexity innate to complex subjects. The purpose of this study was to build on the limited research into intrinsic cognitive load, by examining the effects of using multimedia screencasts as a pre-training technique to manage the intrinsic cognitive load of chemical equilibrium instruction for advanced high school chemistry students. A convenience sample of 62 fourth-year high school students enrolled in an advanced chemistry course from a co-ed high school in urban San Francisco were given a chemical equilibrium concept pre-test. Upon conclusion of the pre-test, students were randomly assigned to two groups: pre-training and no pre-training. The pre-training group received a 10 minute and 52 second pre-training screencast that provided definitions, concepts and an overview of chemical equilibrium. After pre-training both group received the same 50-minute instructional lecture. After instruction, all students were given a chemical equilibrium concept post-test. Independent sample t-tests were conducted to examine differences in performance and intrinsic load. No significant differences in performance or intrinsic load, as measured by ratings of mental effort, were observed on the pre-test. Significant differences in performance, t(60)=3.70, p=.0005, and intrinsic load, t(60)=5.34, p=.0001, were observed on the post-test. A significant correlation between total performance scores and total mental effort ratings was also observed, r(60)=-0.44, p=.0003. Because no significant differences in prior knowledge were observed, it can be concluded that pre-training was successful at reducing intrinsic load. Moreover, a significant

    Total occlusion of a coronary artery for more than 3 months is defined as chronic total occlusion (CTO). The goal of this study was to develop a risk score in predicting failure or success during attempted percutaneous coronary intervention (PCI) of CTO lesions using antegrade approach. This study was based on retrospective analyses of clinical and angiographic characteristics of CTO lesions that were assessed between February 2012 and February 2014. Success rate was defined as passing through occlusion with successful stent deployment using an antegrade approach. A total of 188 patients were studied. Mean ± SD age was 59 ± 9 years. Failure rate was 33%. In a stepwise multivariate regression analysis, bridging collaterals (OR = 6.7, CI = 1.97-23.17, score = 2), absence of stump (OR = 5.8, CI = 1.95-17.9, score = 2), presence of calcification (OR = 3.21, CI = 1.46-7.07, score = 1), presence of bending (OR = 2.8, CI = 1.28-6.10, score = 1), presence of near side branch (OR = 2.7, CI = 1.08-6.57, score = 1), and absence of retrograde filling (OR = 2.5, CI = 1.03-6.17, score = 1) were independent predictors of PCI failure. A score of 7 or more was associated with 100% failure rate whereas a score of 2 or less was associated with over 80% success rate. Most factors associated with failure of CTO-PCI are related to lesion characteristics. A new risk score (range 0-8) is developed to predict CTO-PCI success or failure rate during antegrade approach as a guide before attempting PCI of CTO lesions.

    The purpose of the present study was to determine the effect of composition (art or music) on the self-concept of hospitalized children. The music composition was created using the program Making More Music. The art composition was a drawing using standard medium. The Piers-Harris Children's Self-Concept Scale was used to measure self-concept. When examining subjects as one group, a significant difference from pre- to posttest for the Total score indicated an improved self-concept. Further analyses on each of the 6 categories indicated no significant differences. The art composition group had a significant difference from pre- to posttest for the Total score and for Popularity (POP). Although not significant, scores increased from pre- to posttest for Behavioral Adjustment (BEH), Physical Appearance (PHY), Freedom from Anxiety (FRE), and Happiness and Satisfaction (HAP). The music composition group had no significant difference from pre- to posttest for the Total score but a significant difference from pre- to posttest on Intellectual and School Status (INT) and Physical Appearance (PRY). Although not significant, scores increased from pre- to posttest for TOT, BEH, and HAP. There was a significant difference between the groups on 2 categories that indicated an improved self-concept for the music group under Intellectual and School Status and for the art group under Popularity.

    Full Text Available The central purpose of this study was to determine whether a single interpersonal communication event could influence perceptions of physical attractiveness in a dating environment. A total of 104 undergraduate students at a large United States university engaged in speed-dating in order to examine the effects of both positive communication and negative communication. Speed-dating was incorporated into the present research because this round-robin method of dating offered an efficient means for investigating attraction and analyzing the effects of a single conversation. It was upon arrival at the event that participants completed a pre-test measure, engaged in a series of three minute speed-dates, and then completed a post-test measure. Results produced evidence of an interaction. Perceptions of physical attractiveness increased from pre-test to post-test in the positive communication condition while perceptions of physical attractiveness decreased from pre-test to post-test in the negative communication condition. Additional findings illustrated that three minutes of non-neutral social interaction had differing effects on women and men. One of the central conclusions from the present research was that females can strategically use interpersonal communication as a tool for enhancing their physical appearance. The results from this study also yielded practical implications that are relevant to casual dating as well as theoretical implications that are germane to communication theory.

    Full Text Available BACKGROUND AND OBJECTIVE: Cancers are a broad group of diseases, each having their own etiology, treatment, and prognosis. The majority of cancer patients experience a period of mental stress during their disease. Given the effective role of life expectancy in dealing with chronic diseases, such as stomach cancer, this study aimed to evaluate the effects of cognitive-behavioral group therapy on increased life expectancy of male patients with gastric cancer. METHODS: This quasi-experiment was conducted on 92 male patients with gastric cancer referring to Tuba Medical Center, Sari, Iran in 2014. Patients were randomly divided into two groups of test (n=46 and control (n=46. The two groups completed the Adult Hope Scale (AHS by Snyder in pretest stage. At the next stage, samples of the test group were exposed to 10 sessions of cognitive-behavioral group therapy (each session: 90 min, while the control group did not receive any special treatment. Both study groups completed the questionnaire again at the posttest stage, followed by the comparison of results. FINDINGS: In terms of life expectancy, mean scores of the test and control groups at the pretest stage were 37.21±4.7 and 36.26±4.73, respectively. Meanwhile, mean scores of the mentioned groups at the posttest stage were 40.02±3.87 and 36.23±4.8, respectively. A significant increase was observed in the mean scores of test and control groups at the posttest stage compared to before the intervention. Moreover, a significant difference was found between the study groups regarding life expectancy and its components (p<0.01. CONCLUSION: According to the results, cognitive-behavioral group therapy could increase life expectancy in patients with gastric cancer.

    Many nurses have difficulty learning to use the complex, non-traditional, and regularly-updated critical care equipment. Failure to use such equipment properly can seriously compromise treatment and endanger patient health and lives. New self-learning materials for novice nurses are necessary to provide essential and effective guidance as a part of formal nursing training. Such materials can enhance the capabilities of critical care nurses and, thus, improve the general quality of critical care. The purpose of this research was to develop a continuous renal replacement therapy (CRRT)-themed self-learning manual that would provide easily absorbed and understood knowledge in an easy-to-carry format for ICU nursing staff. This study also investigated CCRT skill learning efficacy. This study adopted a quasi-experimental design with pretests and posttests. Purposive sampling generated a sample of 66 critical care nurses currently working at one hospital in Taipei City. Participants submitted a completed self-assessment survey that rated their command of continuous renal replacement therapy before and after the self-learning manual intervention. Survey data were analyzed using SPSS Version 17.0 for Windows. The two major findings derived from the study included: (1) The mean response score from the self-assessment survey filled out after the intervention was 91.06 and 79.75 (SD = 9.49 and 11.65), respectively, for experimental and control groups. Such demonstrated significant difference. (2) The mean posttest score after the intervention for the experimental group was 91.06 ± 9.49. This represents a significant increase of 10.35 ± 10.35 over their mean pretest score (80.71 ± 11.82). The experimental group showed other significant differences in terms of the CRRT self-assessment survey posttest. Self-learning manuals may be introduced in nursing education as useful aids and catalysts to achieve more effective and satisfying learning experiences.

    The research was conducted by a pretest and post-test conducted in a quasi-experimental design which aimed to determine effectiveness of Aggression Replacement Training (ART) on problem solving, anger and aggressive behaviour among adolescents with criminal attempts in Turkey. The study included 65 adolescents with criminal attempts (32 intervention, 33 control). There was no difference between the groups in terms of average age (16.13±1.10 in the experimental group and 16.21±0.89 in the control group). After the intervention, the experimental group showed significantly decreased Trait Anger levels (t=1.906; P=0.033), increased Anger Control scores (t=2.522; P=0.008), decreased Physical Aggression scores (t=1.925; P=0.031), decreased Hostility scores (t=2.496; P=0.009), increased Social Problem Solving total scores (t=2.937; P=0.005). Increased Anger Control scores were found to be significant when compared with the control group (t=2.273, P=0.026). These results showed that ART was effective on problem solving, anger and aggressive behaviour and can be used to develop positive behaviours among adolescents with criminal attempts.

    Physiology is a requisite course for many professional allied health programs and is a foundational science for learning pathophysiology, health assessment, and pharmacology. Given the demand for online learning in the health sciences, it is important to evaluate the efficacy of online and in-class teaching methods, especially as they are combined to form hybrid courses. The purpose of this study was to compare two hybrid physiology sections in which one section was offered mostly in-class (85% in-class), and the other section was offered mostly online (85% online). The two sections in 2 yr ( year 1 and year 2 ) were compared in terms of knowledge of physiology measured in exam scores and pretest-posttest improvement, and in measures of student satisfaction with teaching. In year 1 , there were some differences on individual exam scores between the two sections, but no significant differences in mean exam scores or in pretest-posttest improvements. However, in terms of student satisfaction, the mostly in-class students in year 1 rated the instructor significantly higher than did the mostly online students. Comparisons between in-class and online students in the year 2 cohort yielded data that showed that mean exam scores were not statistically different, but pre-post changes were significantly greater in the mostly online section; student satisfaction among mostly online students also improved significantly. Education researchers must investigate effective combinations of in-class and online methods for student learning outcomes, while maintaining the flexibility and convenience that online methods provide.

    Full Text Available Background: Early in the postpartum period, mothers are often nervous and tired from the delivery, breast-feeding and caring for a new-born. The aim of this study was to evaluate the process and outcome of using aromatherapy treatments to increase relaxation and decrease fatigue for mothers during the first to the seventh day of the postpartum period. Methods: This non-randomized controlled study with a quasi-experimental one-group pretest-posttest design was used to evaluate scores in relaxation and fatigue before and after the intervention. Aromatherapy hand treatments were performed on a purposive sample of 34 postpartum mothers in Tokyo, Japan, from May to July 2016. The single treatment included a choice of one of five essential aroma oils through hand and forearm massage. Relaxation and fatigue were measured by self-administered valid and reliable questionnaires. Wilcoxon signed-rank test was conducted to analyze the data before and after the intervention. The software programs SPSS, v. 23.0 (SPSS, Tokyo, was used to analyze the data, with the significance level set at 5%. Results: Valid responses were obtained from 29 participants. A comparison of the scores before and after aroma treatment intervention indicated that the participants’ relaxation scores increased significantly (P<0.001 and fatigue scores were significantly reduced (P<0.001. The majority of participants (77.8% were satisfied with the treatment. Conclusion: The aroma treatments significantly improved relaxation and reduced fatigue for mothers in the early puerperal period and were well received. Therefore, a larger study using a pretest-posttest random control trial is recommended.

    Point-of-care ultrasound is an effective tool for clinical decision making in low- and middle-income countries, but lack of trained providers is a barrier to its utility in these settings. In Liberia, given that midwives provide most prenatal care, it is hypothesized that training them in prenatal ultrasound through an intensive condensed training course is both feasible and practical. This quantitative prospective study of preobservational and postobservational assessment evaluated a 1-week ultrasound curriculum consisting of 4 modules, each comprising a didactic component, a practical session, and supervised patient encounters. A knowledge-based pretest and presurvey addressing prior use and comfort were administered. At the intervention conclusion, identical posttests and postsurveys were administered with an objective structured clinical examination (OSCE). The test, survey, and OSCE were repeated after 1 year. All scores and responses were tabulated, and qualitative analysis with paired t tests was performed. Thirty-one midwives underwent intervention and written evaluation, with 14 followed up at 1 year. Seventeen underwent the OSCE, with 8 retained at 1 year. There was a significant increase between pretest and immediate and 1-year posttest scores (36.6% versus 90% and 66%; P .05). Average overall comfort using ultrasound increased from presurvey to immediate postsurvey scores (from 1.8 to 3.8; P .05). Midwives in Liberia had very low baseline knowledge and comfort using ultrasound. A 1-week curriculum increased both short- and long-term knowledge and comfort and led to adequate overall OSCE scores that were retained at 1 year. © 2015 by the American Institute of Ultrasound in Medicine.

    The purpose of this study was to develop an integrated internet addiction prevention program and test its effects on the self-regulation and internet addiction of elementary students who are at risk for internet addiction. A quasi-experimental study with a nonequivalent control group pretest-posttest design was used. Participants were assigned to the experimental group (n=28) or control group (n=28). Contents of the program developed in this study included provision of information about internet addiction, interventions for empowerment and methods of behavioral modification. A pre-test and two post-tests were done to identify the effects of the program and their continuity. Effects were testified using Repeated measures ANOVA, simple effect analysis, and Time Contrast. The self-regulation of the experimental group after the program was significantly higher than the control group. The score for internet addiction self-diagnosis and the internet use time in the experimental group were significantly lower than the control group. The effects of the integrated internet addiction prevention program for preventing internet addiction in elementary students at risk for internet addiction were validated.

    Nurses need to be well prepared to address the needs of a diverse population and facilitate positive experiences in an equitable and inclusive approach to care. The aim of the study was to determine whether the integration of consumer lived experience interviews into the content of a first-year course influenced empathy in nursing students. A one group pre-test, post-test design was used. A convenience sample of first-year undergraduate nursing students (N = 32) from a regional Australian university was recruited for the study. The pre and post tests were conducted using the Kiersma Chen Empathy Scale and t-tests performed to analyse the data. Results showed overall that nursing students demonstrated moderate levels of empathy; pre-test score of (M = 75.53; SD = 5.76). After the intervention the post-test results showed that there was a statistically significant increase in students' empathy towards vulnerable, disadvantaged and stigmatised population groups. The healthcare consumer voice has the potential to strengthen current teaching practices that promote caring behaviours in nursing students. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The aim of this study was to investigate that listening to music reduces the anxiety and distress of the patients who underwent ultrasound guided core biopsy in a clinic. One hundred patients underwent Ultrasound Guided Core Biopsy of the Breast. Each patients was allocated to one of two groups with different methods whether they listened to music or not. The experimental group listening to music are 50 patients and the control group are 50 patients. The difference of VAS anxiety score of pre-test and post-test was signifcant (p<0.001). Compared by the control group, the subjective distress of the patients listening to music such as pain and tension was significant (p<0.001) but nausea and dyspnea was not significant. The objective distress of the patients listening to music was statistically significant (p<0.001). The Differances of systolic blood pressure, diastolic blood pressure, pulse between pre-test and post-test were not signifcant. The results suggest that listening to music reduces the anxiety and distress of the patients who underwent ultrasound guided core biopsy in a clinic.

    SAGES FUSE curriculum provides didactic knowledge on OR fire prevention. The objective of this study is to evaluate the impact of an immersive virtual reality (VR)-based OR fire training simulation system in combination with FUSE didactics. The study compared a control with a simulation group. After a pre-test questionnaire that assessed the baseline knowledge, both groups were given didactic material that consists of a 10-min presentation and reading materials about precautions and stopping an OR fire from the FUSE manual. The simulation group practiced on the OR fire simulation for one session that consisted of five trials within a week from the pre-test. One week later, both groups were reassessed using a questionnaire. A week after the post-test both groups also participated in a simulated OR fire scenario while their performance was videotaped for assessment. A total of 20 subjects (ten per group) participated in this IRB approved study. Median test scores for the control group increased from 5.5 to 9.00 (p = 0.011) and for the simulation group it increased from 5.0 to 8.5 (p = 0.005). Both groups started at the same baseline (pre-test, p = 0.529) and reached similar level in cognitive knowledge (post-test, p = 0.853). However, when tested in the mock OR fire scenario, 70% of the simulation group subjects were able to perform the correct sequence of steps in extinguishing the simulated fire whereas only 20% subjects in the control group were able to do so (p = 0.003). The simulation group was better than control group in correctly identifying the oxidizer (p = 0.03) and ignition source (p = 0.014). Interactive VR-based hands-on training was found to be a relatively inexpensive and effective mode for teaching OR fire prevention and management scenarios.

    Asynchronous e-learning allows for targeted teaching, particularly advantageous when bedside and didactic education is insufficient. An asynchronous e-learning curriculum has not been studied across multiple centers in the context of a clinical rotation. We hypothesize that an asynchronous e-learning curriculum during the pediatric emergency medicine (EM) rotation improves medical knowledge among residents and students across multiple participating centers. Trainees on pediatric EM rotations at four large pediatric centers from 2012 to 2013 were randomized in a Solomon four-group design. The experimental arms received an asynchronous e-learning curriculum consisting of nine Web-based, interactive, peer-reviewed Flash/HTML5 modules. Postrotation testing and in-training examination (ITE) scores quantified improvements in knowledge. A 2 × 2 analysis of covariance (ANCOVA) tested interaction and main effects, and Pearson's correlation tested associations between module usage, scores, and ITE scores. A total of 256 of 458 participants completed all study elements; 104 had access to asynchronous e-learning modules, and 152 were controls who used the current education standards. No pretest sensitization was found (p = 0.75). Use of asynchronous e-learning modules was associated with an improvement in posttest scores (p effect (partial η(2) = 0.19). Posttest scores correlated with ITE scores (r(2) = 0.14, p e-learning is an effective educational tool to improve knowledge in a clinical rotation. Web-based asynchronous e-learning is a promising modality to standardize education among multiple institutions with common curricula, particularly in clinical rotations where scheduling difficulties, seasonality, and variable experiences limit in-hospital learning. © 2014 by the Society for Academic Emergency Medicine.

    This article discusses the development and pretesting of key visual imagery in a promotional campaign developed in Quebec, Canada. This campaign is the media-based component of a broader prevention strategy involving the use of the Triple P program (Sanders, 1999). The purpose was to pretest with parents the preliminary version of a poster that uses the campaign's key visual imagery prior to final production. In total, 26 parents from the regions of Quebec City and Montreal participated in four focus groups. Two general themes emerged from the focus groups: (i) emotions and reactions arising from the key visual imagery; and (ii) comprehension of the message being conveyed. Based on this information, recommendations were made to the marketing agency, which then modified the campaign's key visual imagery and proposed a final layout.

    There is a push to use classroom technology and active teaching methods to replace didactic lectures as the most prevalent format for resident education. This multisite collaborative cohort study involving nine residency programs across the United States compared a standard slide-based didactic lecture, a facilitated group discussion via an engaged classroom, and a high-fidelity, hands-on simulation scenario for teaching the topic of acute dyspnea. The primary outcome was knowledge retention at 2 to 4 weeks. Each teaching method was assigned to three different residency programs in the collaborative according to local resources. Learning objectives were determined by faculty. Pre- and posttest questions were validated and utilized as a measurement of knowledge retention. Each site administered the pretest, taught the topic of acute dyspnea utilizing their assigned method, and administered a posttest 2 to 4 weeks later. Differences between the groups were compared using paired t-tests. A total of 146 residents completed the posttest, and scores increased from baseline across all groups. The average score increased 6% in the standard lecture group (n=47), 11% in the engaged classroom (n=53), and 9% in the simulation group (n=56). The differences in improvement between engaged classroom and simulation were not statistically significant. Compared to standard lecture, both engaged classroom and high-fidelity simulation were associated with a statistically significant improvement in knowledge retention. Knowledge retention after engaged classroom and high-fidelity simulation did not significantly differ. More research is necessary to determine if different teaching methods result in different levels of comfort and skill with actual patient care.

    Full Text Available The present study aimed to investigate the effectiveness of group cognitive behavioral therapy in reducing anxiety and depression and glycemic control in children with type I diabetes. The study was quasi- experimental with a pre-test, post-test design with control group. For this purpose, 30 children with diabetes were selected from Imam Reza Hospital in Mashhad. The children were randomly assigned into two experimental group (15 and control group (15. The experimental group was undergone eight 2-hour sessions of cognitive-behavioral training. Before and after the intervention, the Multidimensional Anxiety Scale for Children, which included four components of social anxiety, physical symptoms, harm avoidance, and separation anxiety, and Children Depression Inventory was administrated in both groups. The findings from the covariance analysis test revealed that depression and anxiety and glycemic control in experimental group was controlled at post-test and depression score in experimental group compared to the control group at post-test was decreased. The findings from the multivariate covariance analysis test between components of, physical symptoms, harm avoidance, separation anxiety, and social anxiety revealed meaningful differences between the two groups in social anxiety post-test score. Thus, cognitive behavior therapy can be effective for depression, anxiety, and blood sugar control in children.

    Purpose: We developed a computer-based interactive simulation program for teaching contrast reaction management to radiology trainees and compared its effectiveness to high-fidelity hands-on simulation training. Materials and methods: IRB approved HIPAA compliant prospective study of 44 radiology residents, fellows and faculty who were randomized into either the high-fidelity hands-on simulation group or computer-based simulation group. All participants took separate written tests prior to and immediately after their intervention. Four months later participants took a delayed written test and a hands-on high-fidelity severe contrast reaction scenario performance test graded on predefined critical actions. Results: There was no statistically significant difference between the computer and hands-on groups’ written pretest, immediate post-test, or delayed post-test scores (p > 0.6 for all). Both groups’ scores improved immediately following the intervention (p < 0.001). The delayed test scores 4 months later were still significantly higher than the pre-test scores (p ≤ 0.02). The computer group's performance was similar to the hands-on group on the severe contrast reaction simulation scenario test (p = 0.7). There were also no significant differences between the computer and hands-on groups in performance on the individual core competencies of contrast reaction management during the contrast reaction scenario. Conclusion: It is feasible to develop a computer-based interactive simulation program to teach contrast reaction management. Trainees that underwent computer-based simulation training scored similarly on written tests and on a hands-on high-fidelity severe contrast reaction scenario performance test as those trained with hands-on high-fidelity simulation.

    Many clinicians use a global visual interpretation of patient appearance to decide if a patient looks sick or not. For patients with suspected acute pulmonary embolism (PE), we tested the relationship between visual appearance of a happy patient facial affect and probability of PE+ on CT pulmonary angiography (CTPA). Eligible patients were selected by usual care to undergo CTPA, the criterion standard for PE+ or PE-. Prior to CTPA result, trained study personnel obtained physician pretest probability using the gestalt method (visual analogue scale, 0%-100%), the Wells score (0-12) and physicians' impression of whether the patient smiled during the initial examination (smile+). Patients' faces were also video recorded and analysed with an automated neural network-based algorithm (Noldus FaceReader) for happy affect. Of the 208 patients enrolled, 27 were PE+ and smile+ was more frequent in patients with PE+ than PE-, a finding confirmed by the Noldus. The diagnostic sensitivity and specificity of smile was low, and physicians overestimated presence of an alternative diagnosis more likely to PE with smile+ than smile- patients in patients with true PE. As a result, the area under the receiver operating characteristic curve (AUROC) was lower for the Wells score in smile+ patients. However, the physicians' mean gestalt estimate of PE did not differ with smile status, nor did smile status affect the AUROC for gestalt. In patients with suspected PE, physician recollection of patients' smile+ was more common in PE+ patients, and was associated with a less accurate Wells score, primarily because physicians overestimated probability of alternative diagnosis. However, the overall diagnostic accuracy of physicians' gestalt did not differ with perceived smile status. These data suggest that the patients' smile had less effect on the numeric gestalt pretest probability assessment than on the binary decision about an alternative diagnosis.

    The formulation and implementation of national ethical regulations to protect research participants is fundamental to ethical conduct of research. Ethics education and capacity are inadequate in developing African countries. This study was designed to develop a module for online training in research ethics based on the Nigerian National Code of Health Research Ethics and assess its ease of use and reliability among biomedical researchers in Nigeria. This was a three-phased evaluation study. Phase one involved development of an online training module based on the Nigerian Code of Health Research Ethics (NCHRE) and uploading it to the Collaborative Institutional Training Initiative (CITI) website while the second phase entailed the evaluation of the module for comprehensibility, readability and ease of use by 45 Nigerian biomedical researchers. The third phase involved modification and re-evaluation of the module by 30 Nigerian biomedical researchers and determination of test-retest reliability of the module using Cronbach's alpha. The online module was easily accessible and comprehensible to 95% of study participants. There were significant differences in the pretest and posttest scores of study participants during the evaluation of the online module (p = 0.001) with correlation coefficients of 0.9 and 0.8 for the pretest and posttest scores respectively. The module also demonstrated excellent test-retest reliability and internal consistency as shown by Cronbach's alpha coefficients of 0.92 and 0.84 for the pretest and posttest respectively. The module based on the Nigerian Code was developed, tested and made available online as a valuable tool for training in cultural and societal relevant ethical principles to orient national and international biomedical researchers working in Nigeria. It would complement other general research ethics and Good Clinical Practice modules. Participants suggested that awareness of the online module should be increased through seminars

    , students completed a pretest, the assigned modules, and a posttest. Success in remediation was measured using normalized gain scores, which measures the change in score divided by the maximum possible increase: (posttest-pretest)/(1-pretest). To compare across courses, normalized gain scores were standardized. Additional analysis included disaggregating normalized gain scores by quartiles based on pretest scores. The results were supplemented by qualitative data from faculty interviews and information provided by faculty on a web form upon completion of the course. Results suggest TMYN modules remediate mathematical skills effectively, and that normalized gains tend to be higher for students in the lower quartiles on the pretest. Students indicate finding the modules helpful, though sometimes difficult. Faculty interview data triangulate these findings and provide further evidence that online, modularized remediation is an effective alternative to assigning prerequisite mathematical courses to remediate mathematical skills.

    This study was designed to determine whether an interactive three-dimensional presentation depicting liver and biliary anatomy is more effective for teaching medical students than a traditional textbook format presentation of the same material. Forty-six medical students volunteered for participation in this study. Baseline demographic information, spatial ability, and knowledge of relevant anatomy were measured. Participants were randomized into two groups and presented with a computer-based interactive learning module comprised of animations and still images to highlight various anatomical structures (3D group), or a computer-based text document containing the same images and text without animation or interactive features (2D group). Following each teaching module, students completed a satisfaction survey and nine-item anatomic knowledge post-test. The 3D group scored higher on the post-test than the 2D group, with a mean score of 74% and 64%, respectively; however, when baseline differences in pretest scores were accounted for, this difference was not statistically significant (P = 0.33). Spatial ability did not statistically significantly correlate with post-test scores for the 3D group or the 2D group. In the post-test satisfaction survey the 3D group expressed a statistically significantly higher overall satisfaction rating compared to students in the 2D control group (4.5 versus 3.7 out of 5, P = 0.02). While the interactive 3D multimedia module received higher satisfaction ratings from students, it neither enhanced nor inhibited learning of complex hepatobiliary anatomy compared to an informationally equivalent traditional textbook style approach. .

Community & Junior College Libraries, 21(1-2, 27-36. http://dx.doi.org/10.1080/02763915.2015.1120623 Abstract Objective – To evaluate the impact of providing multiple information literacy (IL sessions, instead of a single “one-shot” session, to students in face-to-face and online English courses. Design – Non-experimental, using pre-test and post-test surveys for one group, and only a post-test survey for the other group. Setting – A small community college in North Carolina, United States of America. Subjects – 352 students enrolled in 2 successive 3-credit English courses, excluding those under the age of 18, for a total of 244 participants. Methods – The researchers selected two English courses, ENG 111 and ENG 112, of which most students were required to take at least one to earn a degree or certification. After consulting with faculty, the researchers designed two workshops for each course that integrated active and group learning techniques. The ENG 111 workshops covered pre-searching (e.g., mind mapping and selecting search terms and database searching in the first session, and website analysis and research (e.g., URLs, Google’s advanced search, and the evaluative CRAAP test in the second session. The ENG 112 workshops covered subject database searching in the first session and evaluative analysis of magazine and scholarly journal articles in the second session. Instructors provided web-based tutorials to online course sections as a substitute for the face-to-face sessions. Course assignments were the same for both online and face-to-face classes. The researchers used anonymous online surveys. ENG 111 students completed pre-test and post-test surveys for their two workshops during the fall 2014 semester. The surveys consisted of seven fill-in-the-blank and multiple-choice questions measuring pre

    Full Text Available Background/Objective: The purpose of this study is to investigate the effect of liquid losses occurring in training sessions during the competition period on some biochemical values of the male Judokas competing in the U18 category. Methods:  The values of the 17 male athletes, who were included in the national team at least once, were checked in our study which compares the values of athletes before the competition and immediately after the competition. Urine Density, Urine pH, BUN, Creatine and Potassium values from the biochemistry values were measured besides the age, height and weight of the athletes participating in the study. Results: As a result of the measurements made; it was found that the kg pre-test averages of the participant athletes were 67,82 ±17,87, post-test averages were 64,88±16,89, Urine Density pre-test averages were 1.017,94 ±7,08, post-test averages were 1.025±8,48, Urine pH pre-test averages were 6,15±0,70, post-test averages were 5,82±0,50, BUN pre-test averages were 15,65±3,14, post-test averages were 24,35±3,60, Creatine pre-test averages were 0,48±0,20, post-test averages were 0,93±0,41,  K Potassium pre-test averages were 4,16±0,35,  post-test averages were 4,95 ±0,64. As a result of the statistical analysis, although there was no significant difference in urine pH pre-test and post-test values, statistically significant difference was found between pre-test and post-test values in other selected parameters (p <0,05. Conclusions: As a result; it is thought that in our country in which the adjustment of the weight class is made unconsciously and unplanned, this will lead to the health problems of the athletes in many ways, especially in the later ages. Particularly in the professional sense, the health problems, which athletes who enter weight competitions and who enter at least 10 international competitions in the Olympic sense for the Judo branch a year can experience in the later ages as a result

    In-training evaluations in graduate medical education have typically been challenging. Although the majority of standardized examination delivery methods have become computer-based, in-training examinations generally remain pencil-paper-based, if they are performed at all. Audience response systems present a novel way to stimulate and evaluate the resident-learner. The purpose of this study was to assess the outcomes of audience response systems testing as compared with traditional testing in a plastic surgery residency program. A prospective 1-year pilot study of 10 plastic surgery residents was performed using audience response systems-delivered testing for the first half of the academic year and traditional pencil-paper testing for the second half. Examination content was based on monthly "Core Quest" curriculum conferences. Quantitative outcome measures included comparison of pretest and posttest and cumulative test scores of both formats. Qualitative outcomes from the individual participants were obtained by questionnaire. When using the audience response systems format, pretest and posttest mean scores were 67.5 and 82.5 percent, respectively; using traditional pencil-paper format, scores were 56.5 percent and 79.5 percent. A comparison of the cumulative mean audience response systems score (85.0 percent) and traditional pencil-paper score (75.0 percent) revealed statistically significantly higher scores with audience response systems (p = 0.01). Qualitative outcomes revealed increased conference enthusiasm, greater enjoyment of testing, and no user difficulties with the audience response systems technology. The audience response systems modality of in-training evaluation captures participant interest and reinforces material more effectively than traditional pencil-paper testing does. The advantages include a more interactive learning environment, stimulation of class participation, immediate feedback to residents, and immediate tabulation of results for the

    Full Text Available Background: Falls are a major problem in the elderly leading to increased morbidity and mortality in this population. Scores from objective clinical measures of balance have frequently been associated with falls in older adults. The Berg Balance Score (BBS which is a frequently used scale to test balance impairments in the elderly ,takes time to perform and has been found to have scoring inconsistencies. The purpose was to determine if individual items or a group of BBS items would have better accuracy than the total BBS in classifying community dwelling elderly individuals according to fall history. Method: 60 community dwelling elderly individuals were chosen based on a history of falls in this cross sectional study. Each BBS item was dichotomized at three points along the scoring scale of 0 – 4: between scores of 1 and 2, 2 and 3, and 3 and 4. Sensitivity (Sn, specificity (Sp, and positive (+LR and negative (-LR likelihood ratios were calculated for all items for each scoring dichotomy based on their accuracy in classifying subjects with a history of multiple falls. These findings were compared with the total BBS score where the cut-off score was derived from receiver operating characteristic curve analysis. Results: On analysing a combination of BBS items, B9 and B11 were found to have the best sensitivity and specificity when considered together. However the area under the curve of these items was 0.799 which did not match that of the total score (AUC= 0.837. A, combination of 4 BBS items - B9 B11 B12 and B13 also had good Sn and Sp but the AUC was 0.815. The combination with the AUC closest to that of the total score was a combination items B11 and B13. (AUC= 0.824. hence these two items can be used as the best predictor of falls with a cut off of 6.5 The ROC curve of the Total Berg balance Scale scores revealed a cut off score of 48.5. Conclusion: This study showed that combination of items B11 and B13 may be best predictors of falls in

    A consistent line of investigation proposes that fibromyalgia is a sympathetically maintained neuropathic pain syndrome. Dorsal root ganglia sodium channels may play a major role in fibromyalgia pain transmission. Ambroxol is a secretolytic agent used in the treatment of various airway disorders. Recently, it was discovered that this compound is also an efficient sodium channel blocker with potent anti-neuropathic pain properties. We evaluated the add-on effect of ambroxol to the treatment of fibromyalgia. We studied 25 patients with fibromyalgia. Ambroxol was prescribed at the usual clinical dose of 30 mg PO 3 times a day × 1 month. At the beginning and at the end of the study, all participants filled out the Revised Fibromyalgia Impact Questionnaire (FIQ-R) and the 2010 ACR diagnostic criteria including the widespread pain index (WPI). At the end of the study, FIQ-R decreased from a baseline value of 62 ± 15 to 51 ± 19 (p = 0.013). Pain visual analogue scale decreased from 77 ± 14 to 56 ± 30 (p = 0.018). WPI diminished from 14.6 ± 3.1 to 10.4 ± 5.3 (p = 0.001). Side effects were minor. In this pilot study, the use of ambroxol was associated to decreased fibromyalgia pain and improved fibromyalgia symptoms. The open nature of our study does not allow extracting the placebo effect from the positive results. The drug was well tolerated. Ambroxol newly recognized pharmacological properties could theoretically interfere with fibromyalgia pain pathways. Dose escalating-controlled studies seem warranted.

    Hanna, Tania Tamara

    Effects of nonfiction guided interactive read-alouds and think-alouds as a supplement to basal science textbooks on three vocabulary measures, definitions, examples, and characteristics, and one multiple-choice comprehension measure were assessed for 127 fourth graders over three time periods: pretest, posttest, and a 2-week delayed posttest. Two of three fourth-grade elementary science teachers implemented a series of 12 content-enhanced guided interactive scripted lessons. Two of these teachers implemented two treatments each. The first condition employed basal science textbooks as the text for guided interactive read-alouds and think-alouds while the second treatment employed basal science textbooks in conjunction with nonfiction text sets as the texts for guided interactive read-alouds and think-alouds. The third teacher, guided by traditional lesson plans, provided students with silent independent reading instruction using basal science textbooks. Multivariate analyses of variance and analyses of variance tests showed that mean scores for both treatment groups significantly improved on definitions and characteristics measures at posttest and either stabilized or slightly declined at delayed posttest. The treatment-plus group lost considerably on the examples posttest measure. The treatment group improved mean scores on the examples posttest measure, outperforming the treatment-plus group and the control group. Alternately, the control group significantly improved on the delayed posttest examples measure. Additionally, the two groups implementing guided interactive read-alouds and think-alouds performed better than the independent reading group on multiple-choice comprehension measures at posttest and sustained those gains 2 weeks later on delayed posttests. Findings maintain the incremental nature of vocabulary acquisition and development research and emphasize the roles of listening and speaking as critical features for integrating vocabulary into long

    Full Text Available Virtual Reality is fast becoming a breakthrough in education technology and is headed towards a path where learning has become immersive. Virtual reality (VR offers both learners and educators a great opportunity to bridge gaps in the pedagogical sense. With the emergence of the Google Cardboard (GCB platform, a low-cost, virtual reality gadget comes a wide range of opportunities for educators and institutions to bring about an immersive type of learning environment for the 21st-century learner. Using Grade 6 Middle school students, this research explores the learning outcomes and student reactions using the GCB and Google Expeditions application. The study showed no significant difference in pre-test scores of the control and experimental group. There is however, a significant difference in the scores of the experimental group compared to the control group after post-test. Utilizing t-test in comparing the two groups, it was found that the mean of the post-test scores for Group A (experimental was significantly higher than Group B(control. The result of the independent samples t-test was significant, t(18 = 2.33, p = .032, suggesting that the mean of posttest score was significantly different between Groups A and B. This difference in score performance gives light to how VR can be used as a tool that enhances the learning experience. By using VR technology that is low cost and effective, more institutions will be able to help students learn better.

    This study aims to evaluate the effect of light therapy on depression and sleep disruption in older adults residing in a long-term care facility. Psychological morbidity is a problem commonly seen in older adults residing in long-term care facilities. Limited research has addressed the effect of light therapy on depression in this population. A quasi-experimental pretest and posttest design was used. Thirty-four participants in the experimental group received light therapy by sitting in front of a 10000-lux light box 30 min in the morning, three times a week for 4 weeks. Thirty-one participants in the control group received routine care without light therapy. Depression was measured by Geriatric Depression Scale-Short Form at baseline and week 4. After receiving 4 weeks of light therapy, the mean depression score in the experimental group decreased from 7.24 (SD3.42) at pretest to 5.91 (SD 3.40) at posttest, and had a significant reduction (t = 2.22, P = 0.03). However, there was no significant difference in depression score and sleep disruption between the experimental group and control group. Light therapy might have the potential to reduce depressive symptoms and sleep disruption and may be a viable intervention to improve mental health of older adults in the long-term care facilities. © 2014 Wiley Publishing Asia Pty Ltd.

    The enormity of modern medical knowledge and the rapidity of change have created increased need for ongoing or continuing medical education (CME) for physicians. Online CME is attractive for its availability at any time and any place, low cost and potentially increased effectiveness compared with traditional face-to-face delivery. To determine whether online CME modules are an effective method for delivering plastic surgery CME to primary care physicians. A needs assessment survey was conducted among all emergency and family physicians in Nova Scotia. Results indicated that this type of program was appealing, and that hand trauma related topics were most desired for CME. 7 Lesson Builder (SoftChalk LLC, www.softchalk.com) was used to construct a multimedia e-learning module that was distributed along with a pretest, post-test and feedback questionnaire. Quantitative (pre- and post-test scores) and qualitative (feedback responses) data were analyzed. The 32 participants who completed the study indicated that it was a positive and enjoyable experience, and that there was a need for more resources like this. Compared with pretest scores, there was a significant gain in knowledge following completion of the module (P=0.001). The present study demonstrated that an e-learning format is attractive for this population and effective in increasing knowledge. This positive outcome will lead to development of additional modules.

    Purpose The purpose of this study was to assess the impact of Diabetes HealthSense on knowledge, attitudes, and behavior changes that prevent, delay, or manage diabetes among people at risk (PAR) for diabetes and people with diabetes (PWD). Methods Using a 2-group pretest-posttest design, 15 community sites were randomly assigned to either an intervention or comparison group. Intervention participants attended a group education session with a diabetes educator, followed by 4 weeks of independent use of the Diabetes HealthSense website. The comparison group received no intervention. A total of 311 adults (n = 135 intervention, n = 176 comparison) completed both a pretest and posttest. Outcome measures examined changes in self-reported knowledge, self-efficacy, and behaviors that support diabetes prevention or management. Results Statistically significant within-group pretest to posttest changes were found for almost all outcome measures in the intervention group, with no significant changes in the comparison group. Significant between-group differences were also found for almost all outcome measures at posttest, with the intervention group having more positive outcomes than the comparison group. Conclusions Patient referral to online tools is considered one key component of initial and ongoing diabetes self-management education and support (DSME/S) and is recommended as a way to enhance and extend the reach of in-person diabetes education. Positive outcomes were found for PWD/PAR who used Diabetes HealthSense following a guided education session. Study results suggested that with guided exploration, Diabetes HealthSense provided a valuable tool for educators to use with patients to support and extend the reach of DSME/S.

    Full Text Available Background: Medical students are expected to master the ability to interpret histopathologic images, a difficult and time-consuming process. A major problem is the issue of transferring information learned from one example of a particular pathology to a new example. Recent advances in cognitive science have identified new approaches to address this problem. Methods: We adapted a new approach for enhancing pattern recognition of basic pathologic processes in skin histopathology images that utilizes perceptual learning techniques, allowing learners to see relevant structure in novel cases along with adaptive learning algorithms that space and sequence different categories (e.g. diagnoses that appear during a learning session based on each learner′s accuracy and response time (RT. We developed a perceptual and adaptive learning module (PALM that utilized 261 unique images of cell injury, inflammation, neoplasia, or normal histology at low and high magnification. Accuracy and RT were tracked and integrated into a "Score" that reflected students rapid recognition of the pathologies and pre- and post-tests were given to assess the effectiveness. Results: Accuracy, RT and Scores significantly improved from the pre- to post-test with Scores showing much greater improvement than accuracy alone. Delayed post-tests with previously unseen cases, given after 6-7 weeks, showed a decline in accuracy relative to the post-test for 1 st -year students, but not significantly so for 2 nd -year students. However, the delayed post-test scores maintained a significant and large improvement relative to those of the pre-test for both 1 st and 2 nd year students suggesting good retention of pattern recognition. Student evaluations were very favorable. Conclusion: A web-based learning module based on the principles of cognitive science showed an evidence for improved recognition of histopathology patterns by medical students.

    Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups. First, the locus of control was measured in both groups through a pretest, and cognitive-behavioral techniques were then taught to the intervention group during eight 45 to 90-minute sessions. The locus of control in patients of both groups was finally re-measured through a posttest. Data were collected using Rotter's Locus of Control Inventory. The Wilcoxon test and Mann-Whitney U test were respectively used in SPSS18 for data analysis. In the pretest and posttest stages respectively, 4.8% and 14.3% of samples in the control group as well as 14.3% and 33.3% of samples in the intervention group enjoyed internal locus of control. The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive

    The present state of physics teaching and learning is a reflection of the difficulty of the subject matter which has resulted in students' low motivation toward physics as well as lack of meaningful and deeper learning experiences. In light of an overall decline in interest in physics, an investigation of alternate teaching and learning methods and tools was appropriate. The research posed the following question: To what extent do online games about kinematics and two-dimensional motion impact student performance in undergraduate general physics as measured by a unit posttest? Two intact classes of 20 students each were randomly assigned to either the experimental group or the control group. Only the experimental group received the treatment of using online games. The duration of topics covered in the game content was identical to the lecture on kinematics and two-dimensional motion. Instructors for the experimental group incorporated online games in their regular classroom teaching, whereas those in the control group continued with their previously used curriculum without games. This study was conducted in three weekly sessions. Although students were not selected using random sampling, existing classes were randomly assigned to either the experimental group or the control group. There were 20 students in the experimental group and 20 students in the control group. The independent samples t test was conducted to compare the means of two independently sampled experimental and control groups. Analysis of covariance (ANCOVA) was used to determine if the two groups were significantly different with regard to their general physics performance on the posttest while controlling for the pretest scores. Analysis of posttest and pretest scores revealed that game-based learning did not significantly impact student performance.

    Previous reports have suggested that action observation training (AOT) is beneficial in enhancing the early learning of new motor tasks; however, EEG-based investigation has received little attention for AOT. The purpose of this study was to illustrate the effects of AOT on hand dexterity and cortical activation in patients with post-stroke hemiparesis. Twenty patients with post-stroke hemiparesis were randomly divided into either the experimental group (EG) or control group (CG), with 10 patients in each group. Prior to the execution of motor tasks (carrying wooden blocks from one box to another), subjects in the EG and CG observed a video clip displaying the execution of the same motor task and pictures showing landscapes, respectively. Outcome measures included the box and block test (BBT) to evaluate hand dexterity and EEG-based brain mapping to detect changes in cortical activation. The BBT scores (EG: 20.50 ± 6.62 at pre-test and 24.40 ± 5.42 at post-test; CG: 20.20 ± 6.12 at pre-test and 20.60 ± 7.17 at post-test) revealed significant main effects for the time and group and significant time-by-group interactions (p < 0.05). For the subjects in the EG, topographical representations obtained with the EEG-based brain mapping system were different in each session of the AOT and remarkable changes occurred from the 2nd session of AOT. Furthermore, the middle frontal gyrus was less active at post-test than at pre-test. These findings support that AOT may be beneficial in altering cortical activation patterns and hand dexterity.
