  1. Extending positive CLASS results across multiple instructors and multiple classes of Modeling Instruction (United States)

    Brewe, Eric; Traxler, Adrienne; de la Garza, Jorge; Kramer, Laird H.


    We report on a multiyear study of student attitudes measured with the Colorado Learning Attitudes about Science Survey in calculus-based introductory physics taught with the Modeling Instruction curriculum. We find that five of six instructors and eight of nine sections using Modeling Instruction showed significantly improved attitudes from pre- to postcourse. Cohen’s d effect sizes range from 0.08 to 0.95 for individual instructors. The average effect was d=0.45, with a 95% confidence interval of (0.26-0.64). These results build on previously published results showing positive shifts in attitudes from Modeling Instruction classes. We interpret these data in light of other published positive attitudinal shifts and explore mechanistic explanations for similarities and differences with other published positive shifts.

  4. Does overgeneral autobiographical memory result from poor memory for task instructions? (United States)

    Yanes, Paula K; Roberts, John E; Carlos, Erica L


    Considerable previous research has shown that retrieval of overgeneral autobiographical memories (OGM) is elevated among individuals suffering from various emotional disorders and those with a history of trauma. Although previous theories suggest that OGM serves the function of regulating acute negative affect, it is also possible that OGM results from difficulties in keeping the instruction set for the Autobiographical Memory Test (AMT) in working memory, or what has been coined "secondary goal neglect" (Dalgleish, 2004). The present study tested whether OGM is associated with poor memory for the task's instruction set, and whether an instruction set reminder would improve memory specificity over repeated trials. Multilevel modelling data-analytic techniques demonstrated a significant relationship between poor recall of instruction set and probability of retrieving OGMs. Providing an instruction set reminder for the AMT relative to a control task's instruction set improved memory specificity immediately afterward.

  5. Show and Tell: Video Modeling and Instruction Without Feedback Improves Performance but Is Not Sufficient for Retention of a Complex Voice Motor Skill. (United States)

    Look, Clarisse; McCabe, Patricia; Heard, Robert; Madill, Catherine J


    Modeling and instruction are frequent components of both traditional and technology-assisted voice therapy. This study investigated the value of video modeling and instruction in the early acquisition and short-term retention of a complex voice task without external feedback. Thirty participants were randomized to two conditions and trained to produce a vocal siren over 40 trials. One group received a model and verbal instructions, the other group received a model only. Sirens were analyzed for phonation time, vocal intensity, cepstral peak prominence, peak-to-peak time, and root-mean-square error at five time points. The model and instruction group showed significant improvement on more outcome measures than the model-only group. There was an interaction effect for vocal intensity, which showed that instructions facilitated greater improvement when they were first introduced. However, neither group reproduced the model's siren performance across all parameters or retained the skill 1 day later. Providing verbal instruction with a model appears more beneficial than providing a model only in the prepractice phase of acquiring a complex voice skill. Improved performance was observed; however, the higher level of performance was not retained after 40 trials in both conditions. Other prepractice variables may need to be considered. Findings have implications for traditional and technology-assisted voice therapy. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

One such factor is self‐initiated deception; in contrast to perpetrators committing real crimes, research participants are typically instructed to

  7. Classroom-based narrative and vocabulary instruction: results of an early-stage, nonrandomized comparison study. (United States)

    Gillam, Sandra Laing; Olszewski, Abbie; Fargo, Jamison; Gillam, Ronald B


    This nonrandomized feasibility study was designed to provide a preliminary assessment of the impact of a narrative and vocabulary instruction program provided by a speech-language pathologist (SLP) in a regular classroom setting. Forty-three children attending 2 first-grade classrooms participated in the study. Children in each classroom were divided into high- and low-risk subgroups on the basis of their performance on a narrative test. Narrative and vocabulary instruction was provided by an SLP in 1 classroom for three 30-min periods per week for 6 weeks. The children in the experimental classroom made clinically significant improvements on narrative and vocabulary measures; children in the comparison classroom did not. Within the experimental classroom, children in the high-risk subgroup demonstrated greater gains in narration and fewer gains in vocabulary than children in the low-risk subgroup. There were no subgroup differences in the comparison classroom. These preliminary results provide early evidence of the feasibility of implementing a narrative instruction program in a classroom setting. Children at a high risk for language difficulties appeared to profit more from the narrative instruction than from the embedded vocabulary instruction. More extensive research on this instructional program is warranted.

  10. Elementary science teachers' integration of engineering design into science instruction: results from a randomised controlled trial (United States)

    Maeng, Jennifer L.; Whitworth, Brooke A.; Gonczi, Amanda L.; Navy, Shannon L.; Wheeler, Lindsay B.


    This randomised controlled trial used a mixed-methods approach to investigate the frequency and how elementary teachers integrated engineering design (ED) principles into their science instruction following professional development (PD). The ED components of the PD were aligned with Cunningham and Carlsen's [(2014). Teaching engineering practices. Journal of Science Teacher Education, 25, 197-210] guidelines for ED PD and promoted inclusion of ED within science teaching. The treatment group included 219 teachers from 83 schools. Participants in the control group included 145 teachers from 60 schools in a mid-Atlantic state. Data sources, including lesson overviews and videotaped classroom observations, were analysed quantitatively to determine the frequency of ED integration and qualitatively to describe how teachers incorporated ED into instruction after attending the PD. Results indicated more participants who attended the PD (55%) incorporated ED into instruction compared with the control participants (24%), χ2(1, n = 401) = 33.225, p .05) through ED lessons. In ED lessons, students typically conducted research and created and tested initial designs. The results suggest the PD supported teachers in implementing ED into their science instruction and support the efficacy of using Cunningham and Carlsen's (2014) guidelines to inform ED PD design.

  11. Gun Shows and Gun Violence: Fatally Flawed Study Yields Misleading Results (United States)

    Hemenway, David; Webster, Daniel; Pierce, Glenn; Braga, Anthony A.


    A widely publicized but unpublished study of the relationship between gun shows and gun violence is being cited in debates about the regulation of gun shows and gun commerce. We believe the study is fatally flawed. A working paper entitled “The Effect of Gun Shows on Gun-Related Deaths: Evidence from California and Texas” outlined this study, which found no association between gun shows and gun-related deaths. We believe the study reflects a limited understanding of gun shows and gun markets and is not statistically powered to detect even an implausibly large effect of gun shows on gun violence. In addition, the research contains serious ascertainment and classification errors, produces results that are sensitive to minor specification changes in key variables and in some cases have no face validity, and is contradicted by 1 of its own authors’ prior research. The study should not be used as evidence in formulating gun policy. PMID:20724672

  13. Transitivity performance, relational hierarchy knowledge and awareness: results of an instructional framing manipulation. (United States)

    Kumaran, Dharshan; Ludwig, Hans


    The transitive inference (TI) paradigm has been widely used to examine the role of the hippocampus in generalization. Here we consider a surprising feature of experimental findings in this task: the relatively poor transitivity performance and levels of hierarchy knowledge achieved by adult human subjects. We focused on the influence of the task instructions on participants' subsequent performance--a single-word framing manipulation which either specified the relation between items as transitive (i.e., OLD-FRAME: choose which item is "older") or left it ambiguous (i.e., NO-FRAME: choose which item is "correct"). We show a marked but highly specific effect of manipulating prior knowledge through instruction: transitivity performance and levels of relational hierarchy knowledge were enhanced, but premise performance unchanged. Further, we show that hierarchy recall accuracy, but not conventional awareness scores, was a significant predictor of inferential performance across the entire group of participants. The current study has four main implications: first, our findings establish the importance of the task instructions, and prior knowledge, in the TI paradigm--suggesting that they influence the size of the overall hypothesis space (e.g., to favor a linear hierarchical structure over other possibilities in the OLD-FRAME). Second, the dissociable effects of the instructional frame on premise and inference performance provide evidence for the operation of distinct underlying mechanisms (i.e., an associative mechanism vs. relational hierarchy knowledge). Third, our findings suggest that a detailed measurement of hierarchy recall accuracy may be a more sensitive index of relational hierarchy knowledge, than conventional awareness score--and should be used in future studies investigating links between awareness and inferential performance. Finally, our study motivates an experimental setting that ensures robust hierarchy learning across participants

  14. Self-directed learning can outperform direct instruction in the course of a modern German medical curriculum - results of a mixed methods trial. (United States)

    Peine, Arne; Kabino, Klaus; Spreckelsen, Cord


    Modernised medical curricula in Germany (so called "reformed study programs") rely increasingly on alternative self-instructed learning forms such as e-learning and curriculum-guided self-study. However, there is a lack of evidence that these methods can outperform conventional teaching methods such as lectures and seminars. This study was conducted in order to compare extant traditional teaching methods with new instruction forms in terms of learning effect and student satisfaction. In a randomised trial, 244 students of medicine in their third academic year were assigned to one of four study branches representing self-instructed learning forms (e-learning and curriculum-based self-study) and instructed learning forms (lectures and seminars). All groups participated in their respective learning module with standardised materials and instructions. Learning effect was measured with pre-test and post-test multiple-choice questionnaires. Student satisfaction and learning style were examined via self-assessment. Of 244 initial participants, 223 completed the respective module and were included in the study. In the pre-test, the groups showed relatively homogenous scores. All students showed notable improvements compared with the pre-test results. Participants in the non-self-instructed learning groups reached scores of 14.71 (seminar) and 14.37 (lecture), while the groups of self-instructed learners reached higher scores with 17.23 (e-learning) and 15.81 (self-study). All groups improved significantly (p learning group, whose self-assessment improved by 2.36. The study shows that students in modern study curricula learn better through modern self-instructed methods than through conventional methods. These methods should be used more, as they also show good levels of student acceptance and higher scores in personal self-assessment of knowledge.

  15. How Teachers' Beliefs About Climate Change Influence Their Instruction and Resulting Student Outcomes (United States)

    Nation, M.; Feldman, A.; Smith, G.


    The purpose of the study was to understand the relationship between teachers' beliefs and understandings of climate change and their instructional practices to determine if and how they impact student outcomes. Limited research has been done in the area of teacher beliefs on climate change, their instruction, and resulting student outcomes. This study contributes to the greater understanding of teachers' beliefs and impact on climate change curriculum implementation. The study utilized a mixed methods approach to data collection and analysis. Data were collected in the form of classroom observations, surveys, and interviews from teachers and students participating in the study over a four-month period. Qualitative and quantitative findings were analyzed through thematic coding and descriptive analysis and compared in an effort to triangulate findings. The results of the study suggest teachers and students believe climate change is occurring and humans are largely to blame. Personal beliefs are important when teaching controversial topics, such as climate change, but participants maintained neutrality within their instruction of the topic, as not to appear biased or influence students' decisions about climate change, and avoid political controversy in the classroom. Overall, the study found teachers' level of understandings and beliefs about climate change had little impact on their instruction and resulting student outcomes. Based on the findings, simply adding climate change to the existing science curriculum is not sufficient for teachers or students. Teachers need to be better prepared about effective pedagogical practices of the content in order to effectively teach a climate-centered curriculum. The barriers that exist for the inclusion of teachers' personal beliefs need to be removed in order for teachers to assert their own personal beliefs about climate change within their classroom instruction. Administrators and stakeholders need to support science

  17. Response to Instruction in Preschool: Results of Two Randomized Studies with Children At Significant Risk of Reading Difficulties (United States)

    Lonigan, Christopher J.; Phillips, Beth M.


    Although response-to-instruction (RTI) approaches have received increased attention, few studies have evaluated the potential impacts of RTI approaches with preschool populations. This manuscript presents results of two studies examining impacts of Tier II instruction with preschool children. Participating children were identified as substantially delayed in the acquisition of early literacy skills despite exposure to high-quality, evidence-based classroom instruction. Study 1 included 93 children (M age = 58.2 months; SD = 3.62) attending 12 Title I preschools. Study 2 included 184 children (M age = 58.2 months; SD = 3.38) attending 19 Title I preschools. The majority of children were Black/African American, and about 60% were male. In both studies, eligible children were randomized to receive either 11 weeks of need-aligned, small-group instruction or just Tier I. Tier II instruction in Study 1 included variations of activities for code- and language-focused domains with prior evidence of efficacy in non-RTI contexts. Tier II instruction in Study 2 included instructional activities narrower in scope, more intensive, and delivered to smaller groups of children. Impacts of Tier II instruction in Study 1 were minimal; however, there were significant and moderate-to-large impacts in Study 2. These results identify effective Tier II instruction but indicate that the context in which children are identified may alter the nature of Tier II instruction that is required. Children identified as eligible for Tier II in an RTI framework likely require more intensive and more narrowly focused instruction than do children at general risk of later academic difficulties.

    To evaluate the performance of Comb-push Ultrasound Shear Elastography (CUSE) for classification of breast masses. CUSE is an ultrasound-based quantitative two-dimensional shear wave elasticity imaging technique, which utilizes multiple laterally distributed acoustic radiation force (ARF) beams to simultaneously excite the tissue and induce shear waves. Female patients who were categorized as having suspicious breast masses underwent CUSE evaluations prior to biopsy. An elasticity estimate within the breast mass was obtained from the CUSE shear wave speed map. Elasticity estimates of various types of benign and malignant masses were compared with biopsy results. Fifty-four female patients with suspicious breast masses from our ongoing study are presented. Our cohort included 31 malignant and 23 benign breast masses. Our results indicate that the mean shear wave speed was significantly higher in malignant masses (6 ± 1.58 m/s) in comparison to benign masses (3.65 ± 1.36 m/s). Therefore, the stiffness of the mass quantified by the Young's modulus is significantly higher in malignant masses. According to the receiver operating characteristic curve (ROC), the optimal cut-off value of 83 kPa yields 87.10% sensitivity, 82.61% specificity, and 0.88 for the area under the curve (AUC). CUSE has the potential for clinical utility as a quantitative diagnostic imaging tool adjunct to B-mode ultrasound for differentiation of malignant and benign breast masses.

  2. AREVA: Operating performance shows distinct improvement; Results heavily impacted by the cost of remedial measures

    International Nuclear Information System (INIS)


    The 2015 results illustrate the progress AREVA made in 2015 and open up favorable prospects for 2016 and the following years in view of its fundamentals. The group's competitiveness plan had a very positive impact on its costs and cash, despite the heavy net loss situation which continues and in a market environment that remained difficult in 2015. Half of this loss of 2 billion Euro is due to additional provisions for OL3 and half to provisions for restructuring and impairment related to market conditions. Concerning the group's liquidity, 2016 is funded and the capital increase which will be launched in the coming months will enable AREVA to gradually regain the group's positive profile. A new phase awaits the Group in 2016 with clarity and confidence in the implementation of the restructuring announced in 2015 and in particular the autonomy of AREVA NP and the creation of New AREVA

    We examined the effect of an instructional video about the production of diagnostic sputum on case detection of tuberculosis (TB), and evaluated the acceptance of the video. Randomized controlled trial. We prepared a culturally adapted instructional video for sputum submission. We analyzed 200 presumptive TB cases coughing for more than two weeks who attended the outpatient department of the governmental Municipal Hospital in Mwananyamala (Dar es Salaam, Tanzania). They were randomly assigned to either receive instructions on sputum submission using the video before submission (intervention group, n = 100) or standard of care (control group, n = 100). Sputum samples were examined for volume, quality and presence of acid-fast bacilli by experienced laboratory technicians blinded to study groups. Median age was 39.1 years (interquartile range 37.0-50.0); 94 (47%) were females, 106 (53%) were males, and 49 (24.5%) were HIV-infected. We found that the instructional video intervention was associated with detection of a higher proportion of microscopically confirmed cases (56%, 95% confidence interval [95% CI] 45.7-65.9%, sputum smear positive patients in the intervention group versus 23%, 95% CI 15.2-32.5%, in the control group, p sex, modified the effectiveness of the intervention by improving it positively. When asked how well the video instructions were understood, the majority of patients in the intervention group reported to have understood the video instructions well (97%). Most of the patients thought the video would be useful in the cultural setting of Tanzania (92%). Sputum submission instructional videos increased the yield of tuberculosis cases through better quality of sputum samples. If confirmed in larger studies, instructional videos may have a substantial effect on the case yield using sputum microscopy and also molecular tests. This low-cost strategy should be considered as part of the efforts to control TB in resource-limited settings. Pan African

  4. Instructional Practices in Introductory Geoscience Courses: Results of a National Faculty Survey (United States)

    MacDonald, R.; Manduca, C. A.; Mogk, D. W.; Tewksbury, B. J.


    The NAGT professional development program "On the Cutting Edge" recently surveyed 7000 geoscience faculty in the United States to develop a snapshot of current instructional practices in undergraduate geoscience courses, faculty strategies for learning new content and new teaching approaches, and faculty involvement in the geoscience education community. Over 2200 faculty responded to the survey which was conducted by the American Institute of Physics. Results for introductory courses (814 responses) indicate that lecture is the most common teaching strategy used in courses of all sizes. Many faculty incorporate some interactive activities in their courses. Most commonly, they use questioning, demonstrations, discussions, and in-class exercises. Less common, but not rare, are small group discussion or think-pair-share and classroom debates or role-playing. Activities involving problem solving, using quantitative skills, working with data and primarily literature, and structured collaboration are incorporated by many faculty in introductory courses, suggesting efforts to teach the process of science. Activities in which students address a problem of national or local interest, analyze their own data, or address problems of their own design are less common but not rare. Field experiences are common but not ubiquitous for students in introductory courses. A wide variety of assessment strategies are used in introductory courses of all sizes, including exams, quizzes, problem sets, papers, oral presentations, and portfolios. While papers are used for assessment more extensively in small classes, a significant number of faculty use papers in large classes (greater than 81 students). A majority of faculty use rubrics in grading. Faculty report that in the past two years, approximately one-third have made changes in the content of their introductory courses while just under half have changed the teaching methods they use. While faculty learn about both new content and

  7. Sustainability Instruction in High Doses: Results From Incorporation of Multiple InTeGrate Modules Into an Environmental Science Class (United States)

    Rademacher, L. K.


    The Interdisciplinary Teaching about Earth for a Sustainable Future (InTeGrate) community has developed extensive courses and modules designed for broad adoption into geoscience classrooms in diverse environments. I participated in a three-semester research project designed to test the efficacy of incorporating "high doses" (minimum 3 modules or 18 class periods) of InTeGrate materials into a course, in my case, an introductory environmental science class. InTeGrate materials were developed by groups of instructors from a range of institutions across the US. These materials include an emphasis on systems thinking, interdisciplinary approaches, and sustainability, and those themes are woven throughout the modules. The three semesters included a control in which no InTeGrate materials were used, a pilot in which InTeGrate materials were tested, and a treatment semesters in which tested materials were modified as needed and fully implemented into the course. Data were collected each semester on student attitudes using the InTeGrate Attitudinal Instrument (pre and post), a subset of Geoscience Literacy Exam questions (pre and post), and a series of assessments and essay exam questions (post only). Although results suggest that learning gains were mixed, changes in attitudes pre- and post-instruction were substantial. Changes in attitudes regarding the importance of sustainable employers, the frequency of self-reported individual sustainable actions, and motivation level for creating a sustainable society were observed in the control and treatment semesters, with the treatment semester showing the greatest gains. Importantly, one of the biggest differences between the control and treatment semesters is the reported impact that the course had on influencing students' sustainable behaviors. The treatment semester course impacted students' sustainable behaviors far more than the control semester.

  13. Reception of Talent Shows in Denmark: First Results from a Trans-National Audience Study of a Global Format Genre

    DEFF Research Database (Denmark)

    Jensen, Pia Majbritt

    This paper will discuss the methodology and present the preliminary findings of the Danish part of a trans-national, comparative audience study of the musical talent show genre undertaken in Denmark, Finland, Germany and Great Britain in Spring 2013. Within the international business model...... of format adaptation, the musical talent show genre has been particularly successful in crossing cultural borders. Formats such as Idols, X Factor and Voice have sold to a large variety of countries, covering all continents. Such global reach inevitably raises the question of the genre’s audience appeal......; to what degree its reach has to do with a universal appeal inherent in the genre and/or the innovative character of individual formats, and to what degree its global success is due to local broadcasters’ ability to successfully adapt the formats to local audience tastes. A consensus has developed...

  15. Bilateral femoral neck fractures resulting from pregnancy-associated osteoporosis showed bone marrow edema on magnetic resonance imaging. (United States)

    Kasahara, Kyoko; Kita, Nobuyuki; Kawasaki, Taku; Morisaki, Shinsuke; Yomo, Hiroko; Murakami, Takashi


    Femoral neck fractures resulting from pregnancy-associated osteoporosis is a rare condition. Herein, we report an undoubted case of pregnancy-associated osteoporosis in a 38-year-old primiparous patient with pre-existing anorexia nervosa who suffered bilateral femoral neck fractures in the third trimester and early post-partum period. Magnetic resonance imaging revealed femoral neck fractures as well as diffuse marrow edema involving both femoral heads, which are considered under ordinary circumstances as characteristic imaging findings of transient osteoporosis of the hip. Based on our experience, we propose that pregnancy-associated osteoporosis might be present in femoral neck fractures attributed to transient osteoporosis of the hip in pregnancy. Conversely, bone status should be carefully and accurately estimated in cases of potential transient osteoporosis of the hip in pregnancy to reduce future fracture risk. © 2017 The Authors Journal of Obstetrics and Gynaecology Research published by John Wiley & Sons Australia, Ltd on behalf of Japan Society of Obstetrics and Gynecology.

  16. Mars Methane at Gale Crater Shows Strong Seasonal Cycle: Updated Results from TLS-SAM on Curiosity (United States)

    Webster, C. R.; Mahaffy, P. R.; Atreya, S. K.; Flesch, G.; Malespin, C.; McKay, C.; Martinez, G.; Moores, J.; Smith, C. L.; Martin-Torres, F. J.; Gomez-Elvira, J.; Zorzano, M. P.; Wong, M.

T.; Crisp, J. A.; Zurek, R. W.; Vasavada, A. R.


    In situ measurements of atmospheric methane have been made over a 5-year period at Gale Crater on Mars using the Tunable Laser Spectrometer (TLS) instrument in the Sample Analysis at Mars (SAM) suite on the Curiosity rover. We report two important observations: (i) a background level of mean value of 0.41 ±0.11 (2sem) that is about 5 times lower than some model predictions based on generation from UV degradation of micro-meteorites or interplanetary dust delivered to the martian surface; (ii) "spikes" of elevated levels of 7 ppbv attributed to episodic releases from small local sources, probably to the north of Gale crater1. Reports of plumes, patches or episodic releases of methane in the Martian atmosphere have to date eluded explanation in part because of their lack of repeatability in time or location. Our in situ measurements of the background methane levels exhibit a strong, repeatable seasonal variability. The amplitude of the observed seasonal cycle is 3 times greater than both that expected from the annual sublimation and freezing of polar carbon dioxide and that expected from methane production from ultraviolet (UV) degradation of exogenously-delivered surface material. The observed large seasonal variation in the background, and sporadic observations of higher pulses of 7 ppbv appear consistent with localized small sources of methane release from Martian surface reservoirs that may be occurring throughout the planet. We will present our updated data set, correlations of Mars methane with various other measurements from SAM, REMS, RAD and ChemCam instruments on Curiosity, as well as empirical models of UV surface insolation, and provide preliminary interpretation of results. 1 "Mars Methane Detection and Variability at Gale Crater", C.

  17. Comprehensive monitoring system - essential tool to show the results of the energy audit and voluntary agreement programmes

    Energy Technology Data Exchange (ETDEWEB)



    Without visible results political support to an energy efficiency programme will dissolve in a few years. Therefore high-quality monitoring and reporting systems are essential to maintain a long-term commitment. Both in Finnish Energy Audit Programme (EAP), began in 1992, and in Voluntary Agreement Scheme (VA), began in 1997, bottom-up monitoring systems have been in place almost since the beginning. These policy measures and their monitoring systems are integrated. For the EAP monitoring system data is collected in three phases: subsidies granted; the energy auditing volumes in different sectors submitted EA reports; proposed measures and saving potentials. VA annual reporting; status of implementation of the proposed measures in EA reports and implementing rate for saving potentials. In VA scheme the companies and communities report annually on their energy consumption and on energy efficiency measures they have implemented or have decided to implement. Information on energy savings in energy units and energy costs as well as the required investment is reported in connection to the presented measures. The collected data is based on engineering calculations by the energy auditors. Since the companies have no incentives to submit exaggerated savings, the reported savings are equal to those figures the companies have used as criteria when deciding on the implementation of the measures. By 2005 these two policy measures have generated about 7 TWh annual savings, representing over 2 % of Finland's total energy end-use. In relation to the magnitude of savings brought in daylight, the investment on monitoring has really paid back.

  18. Instruction in teaching and teaching opportunities for residents in US dermatology programs: Results of a national survey. (United States)

    Burgin, Susan; Homayounfar, Gelareh; Newman, Lori R; Sullivan, Amy


    Dermatology residents routinely teach junior co-residents and medical students. Despite the importance of teaching skills for a successful academic career, no formal teaching instruction programs for dermatology residents have been described to our knowledge, and the extent of teaching opportunities for dermatology residents is unknown. We sought to describe the range of teaching opportunities and instruction available to dermatology residents and to assess the need for additional teaching training from the perspective of dermatology residency program directors nationwide. A questionnaire was administered to 113 US dermatology residency program directors or their designees. Descriptive statistics were used to analyze questionnaire item responses. The response rate was 55% (62/113). All program directors reported that their residents teach; 59% (33/56) reported offering trainees teaching instruction; 11% (7/62) of programs offered a short-term series of formal sessions on teaching; and 7% (4/62) offered ongoing, longitudinal training. Most program directors (74%, 40/54) believed that their residents would benefit from more teaching instruction. Response rate and responder bias are potential limitations. Dermatology residents teach in a broad range of settings, over half receive some teaching instruction, and most dermatology residency program directors perceive a need for additional training for residents as teachers.

  19. Mathematics beliefs and instructional strategies in achievement of elementary-school students in Japan: results from the TIMSS 2003 assessment. (United States)

    House, J Daniel


    Recent findings concerning mathematics assessment indicate that students in Japan consistently score above international averages. Researchers have examined specific mathematics beliefs and instructional strategies associated with mathematics achievement for students in Japan. This study examined relationships among self-beliefs, classroom instructional strategies, and mathematics achievement for a large national sample of students (N=4,207) from the TIMSS 2003 international sample of fourth graders in Japan. Several significant relationships between mathematics beliefs and test scores were found; a number of classroom teaching strategies were also significantly associated with test scores. However, multiple regression using the complete set of five mathematics beliefs and five instructional strategies explained only 25.1% of the variance in mathematics achievement test scores.

    expressive reading and information reception and comprehension; and C critical and creative reading and creative information processing. The students assigned to the experimental group learnt about and acquired literary theory concepts and special characteristics of literary genres within their 'zones of proximal development,' while the lessons taught to the control group were structured to suit an average or imaginary student. The same requirements were set on all students in the control group, regardless of their individual level of familiarity with literary theory notions and concepts and the degree to which they were capable of comprehending and experiencing a literary text. The results of the experiment carried out with such parallel groups show that the achievement of the students included in the experimental group, who were taught according to individualized instruction plans, was better in a way that was statistically significant, in comparison with both their knowledge of the subject matter before the experiment and the control group, whose members attended classes organized in a predominantly traditional, non-individualistic way.

  2. Dissemination of CPR video self-instruction materials to secondary trainees: results from a hospital-based CPR education trial (United States)

    Ikeda, Daniel J.; Buckler, David G.; Li, Jiaqi; Agarwal, Amit K.; Di Taranti, Laura J.; Kurtz, James; dos Reis, Ryan; Leary, Marion; Abella, Benjamin S.; Blewer, Audrey L.


    Background Cardiopulmonary resuscitation (CPR) video self-instruction (VSI) materials have been promoted as a scalable approach to increase the prevalence of CPR skills among the lay public, in part due to the opportunity for secondary training (i.e., sharing of training materials). However, the motivations for, and barriers to, disseminating VSI materials to secondary trainees is poorly understood. Methods This work represents an ancillary investigation of a prospective hospital-based CPR education trial in which family members of cardiac patients were trained using VSI. Mixed-methods surveys were administered to primary trainees six months after initial enrollment. Surveys were designed to capture motivations for, and barriers to, sharing VSI materials, the number of secondary trainees with whom materials were shared, and the settings, timing, and recipients of trainings. Results Between 07/2012–05/2015, 653 study participants completed a six-month follow-up interview. Of those, 345 reported sharing VSI materials with 1455 secondary trainees. Materials were shared most commonly with family members. In a logistic regression analysis, participants in the oldest quartile (age > 63 years) were less likely to share materials compared to those in the youngest quartile (age ≤ 44 years, OR 0.58, CI 0.37–0.90, p=0.02). Among the 308 participants who did not share their materials, time constraints was the most commonly cited barrier for not sharing. Conclusions VSI materials represent a strategy for secondary dissemination of CPR training, yet older individuals have a lower likelihood of sharing relative to younger individuals. Further work is warranted to remedy perceived barriers to CPR dissemination among the lay public using VSI approaches. PMID:26776900

  6. Influence of verbal instructions on effect-based action control. (United States)

    Eder, Andreas B; Dignath, David


    According to ideomotor theory, people use bidirectional associations between movements and their effects for action selection and initiation. Our experiments examined how verbal instructions of action effects influence response selection without prior experience of action effects in a separate acquisition phase. Instructions for different groups of participants specified whether they should ignore, attend, learn, or intentionally produce acoustic effects produced by button presses. Results showed that explicit instructions of action-effect relations trigger effect-congruent action tendencies in the first trials following the instruction; in contrast, no evidence for effect-based action control was observed in these trials when instructions were to ignore or to attend to the action effects. These findings show that action-effect knowledge acquired through verbal instruction and direct experience is similarly effective for effect-based action control as long as the relation between the movement and the effect is clearly spelled out in the instruction.

  7. The impact of inquiry-based instructional professional development upon instructional practice: An action research study (United States)

    Broom, Frances A.

    This mixed method case study employs action research, conducted over a three month period with 11 elementary math and science practitioners. Inquiry as an instructional practice is a vital component of math and science instruction and STEM teaching. Teachers examined their beliefs and teaching practices with regard to those instructional factors that influence inquiry instruction. Video-taped lessons were compared to a rubric and pre and post questionnaires along with two interviews which informed the study. The results showed that while most beliefs were maintained, teachers implemented inquiry at a more advanced level after examining their teaching and reflecting on ways to increase inquiry practices. Because instructional practices provide only one component of inquiry-based instruction, other components need to be examined in a future study.

  11. Using assessment to individualize early mathematics instruction. (United States)

    Connor, Carol McDonald; Mazzocco, Michèle M M; Kurz, Terri; Crowe, Elizabeth C; Tighe, Elizabeth L; Wood, Taffeta S; Morrison, Frederick J


    Accumulating evidence suggests that assessment-informed personalized instruction, tailored to students' individual skills and abilities, is more effective than more one-size-fits-all approaches. In this study, we evaluate the efficacy of Individualizing Student Instruction in Mathematics (ISI-Math) compared to Reading (ISI-Reading) where classrooms were randomly assigned to ISI-Math or ISI-Reading. The literature on child characteristics X instruction or skill X treatment interaction effects point to the complexities of tailoring instruction for individual students who present with constellations of skills. Second graders received mathematics instruction in small flexible learning groups based on their assessed learning needs. Results of the study (n=32 teachers, 370 students) revealed significant treatment effects on standardized mathematics assessments. With effect sizes (d) of 0.41-0.60, we show that we can significantly improve 2nd graders' mathematics achievement, including for children living in poverty, by using assessment data to individualize the mathematics instruction they receive. The instructional regime, ISI-Math, was implemented by regular classroom teachers and it led to about a 4-month achievement advantage on standardized mathematics tests when compared to students in control classrooms. These results were realized within one school year. Moreover, treatment effects were the same regardless of school-level poverty and students' gender, initial mathematics or vocabulary scores.

  13. Prospects of an alternative treatment against Trypanosoma cruzi based on abietic acid derivatives show promising results in Balb/c mouse model. (United States)

    Olmo, F; Guardia, J J; Marin, C; Messouri, I; Rosales, M J; Urbanová, K; Chayboun, I; Chahboun, R; Alvarez-Manzaneda, E J; Sánchez-Moreno, M


    Chagas disease, caused by the protozoa parasite Trypanosoma cruzi, is an example of extended parasitaemia with unmet medical needs. Current treatments based on old-featured benznidazole (Bz) and nifurtimox are expensive and do not fulfil the criteria of effectiveness, and a lack of toxicity devoid to modern drugs. In this work, a group of abietic acid derivatives that are chemically stable and well characterised were introduced as candidates for the treatment of Chagas disease. In vitro and in vivo assays were performed in order to test the effectiveness of these compounds. Finally, those which showed the best activity underwent additional studies in order to elucidate the possible mechanism of action. In vitro results indicated that some compounds have low toxicity (i.e. >150 μM, against Vero cell) combined with high efficacy (i.e. <20 μM) against some forms of T. cruzi. Further in vivo studies on mice models confirmed the expectations of improvements in infected mice. In vivo tests on the acute phase gave parasitaemia inhibition values higher those of Bz, and a remarkable decrease in the reactivation of parasitaemia was found in the chronic phase after immunosuppression of the mice treated with one of the compounds. The morphological alterations found in treated parasites with our derivatives confirmed extensive damage; energetic metabolism disturbances were also registered by (1)H NMR. The demonstrated in vivo activity and low toxicity, together with the use of affordable starting products and the lack of synthetic complexity, put these abietic acid derivatives in a remarkable position toward the development of an anti-Chagasic agent.

    Full Text Available Mutations in the valosin containing protein (VCP gene cause hereditary Inclusion body myopathy (hIBM associated with Paget disease of bone (PDB, frontotemporal dementia (FTD, more recently termed multisystem proteinopathy (MSP. Affected individuals exhibit scapular winging and die from progressive muscle weakness, and cardiac and respiratory failure, typically in their 40s to 50s. Histologically, patients show the presence of rimmed vacuoles and TAR DNA-binding protein 43 (TDP-43-positive large ubiquitinated inclusion bodies in the muscles. We have generated a VCPR155H/+ mouse model which recapitulates the disease phenotype and impaired autophagy typically observed in patients with VCP disease. Autophagy-modifying agents, such as rapamycin and chloroquine, at pharmacological doses have previously shown to alter the autophagic flux. Herein, we report results of administration of rapamycin, a specific inhibitor of the mechanistic target of rapamycin (mTOR signaling pathway, and chloroquine, a lysosomal inhibitor which reverses autophagy by accumulating in lysosomes, responsible for blocking autophagy in 20-month old VCPR155H/+ mice. Rapamycin-treated mice demonstrated significant improvement in muscle performance, quadriceps histological analysis, and rescue of ubiquitin, and TDP-43 pathology and defective autophagy as indicated by decreased protein expression levels of LC3-I/II, p62/SQSTM1, optineurin and inhibiting the mTORC1 substrates. Conversely, chloroquine-treated VCPR155H/+ mice revealed progressive muscle weakness, cytoplasmic accumulation of TDP-43, ubiquitin-positive inclusion bodies and increased LC3-I/II, p62/SQSTM1, and optineurin expression levels. Our in vitro patient myoblasts studies treated with rapamycin demonstrated an overall improvement in the autophagy markers. Targeting the mTOR pathway ameliorates an increasing list of disorders, and these findings suggest that VCP disease and related neurodegenerative multisystem

  15. Evaluation of a Theory of Instructional Sequences for Physics Instruction (United States)

    Wackermann, Rainer; Trendel, Georg; Fischer, Hans E.


    The background of the study is the theory of basis models of teaching and learning, a comprehensive set of models of learning processes which includes, for example, learning through experience and problem-solving. The combined use of different models of learning processes has not been fully investigated and it is frequently not clear under what circumstances a particular model should be used by teachers. In contrast, the theory under investigation here gives guidelines for choosing a particular model and provides instructional sequences for each model. The aim is to investigate the implementation of the theory applied to physics instruction and to show if possible effects for the students may be attributed to the use of the theory. Therefore, a theory-oriented education programme for 18 physics teachers was developed and implemented in the 2005/06 school year. The main features of the intervention consisted of coaching physics lessons and video analysis according to the theory. The study follows a pre-treatment-post design with non-equivalent control group. Findings of repeated-measures ANOVAs show large effects for teachers' subjective beliefs, large effects for classroom actions, and small to medium effects for student outcomes such as perceived instructional quality and student emotions. The teachers/classes that applied the theory especially well according to video analysis showed the larger effects. The results showed that differentiating between different models of learning processes improves physics instruction. Effects can be followed through to student outcomes. The education programme effect was clearer for classroom actions and students' outcomes than for teachers' beliefs.

  18. The Mere Exposure Instruction Effect. (United States)

    Van Dessel, Pieter; Mertens, Gaëtan; Smith, Colin Tucker; De Houwer, Jan


    The mere exposure effect refers to the well-established finding that people evaluate a stimulus more positively after repeated exposure to that stimulus. We investigated whether a change in stimulus evaluation can occur also when participants are not repeatedly exposed to a stimulus, but are merely instructed that one stimulus will occur frequently and another stimulus will occur infrequently. We report seven experiments showing that (1) mere exposure instructions influence implicit stimulus evaluations as measured with an Implicit Association Test (IAT), personalized Implicit Association Test (pIAT), or Affect Misattribution Procedure (AMP), but not with an Evaluative Priming Task (EPT), (2) mere exposure instructions influence explicit evaluations, and (3) the instruction effect depends on participants' memory of which stimulus will be presented more frequently. We discuss how these findings inform us about the boundary conditions of mere exposure instruction effects, as well as the mental processes that underlie mere exposure and mere exposure instruction effects.

  19. The skeletal trauma resulting from a fatal B.A.S.E jump: A case study showing the impact of landing feet-first under extreme vertical deceleration. (United States)

    Rowbotham, Samantha K; Blau, Soren; Hislop-Jambrich, Jacqueline


    The term 'B.A.S.E jump' refers to jumping from a building, antenna, span (i.e., bridge) or earth (i.e., cliff) structure, and parachuting to the ground. There are numerous hazards associated with B.A.S.E jumps which often result in injury and, occasionally, fatality. This case report details the skeletal trauma resulting from a fatal B.A.S.E jump in Australia. In this case, the jumper impacted the ground from a fall of 439m in a feet-first landing position, as a result of a partially deployed parachute, under extreme vertical deceleration. Skeletal trauma was analyzed using full-body post mortem computed tomography (PMCT) and contextual information related to the circumstances of the jump as reported by the Coroner. Trauma to 61 skeletal elements indicates the primary impact was to the feet (i.e., feet-first landing), followed by an anterior impact to the body (i.e., fall forwards). Details of the individual fracture morphologies indicate the various forces and biomechanics involved in this fall event. This case presents the types of fractures that result from a B.A.S.E jump, and highlights the value of using PMCT and coronial data as tools to augment skeletal trauma interpretations.

  4. Empty polyetheretherketone (PEEK) cages in anterior cervical diskectomy and fusion (ACDF) show slow radiographic fusion that reduces clinical improvement: results from the prospective multicenter "PIERCE-PEEK" study. (United States)

    Suess, Olaf; Schomaker, Martin; Cabraja, Mario; Danne, Marco; Kombos, Theodoros; Hanna, Michael


    Anterior cervical diskectomy and fusion (ACDF) is a well-established surgical treatment for radiculopathy and myelopathy. Previous studies showed that empty PEEK cages have lower radiographic fusion rates, but the clinical relevance remains unclear. This paper's aim is to provide high-quality evidence on the outcomes of ACDF with empty PEEK cages and on the relevance of radiographic fusion for clinical outcomes. This large prospective multicenter clinical trial performed single-level ACDF with empty PEEK cages on patients with cervical radiculopathy or myelopathy. The main clinical outcomes were VAS (0-10) for pain and NDI (0-100) for functioning. Radiographic fusion was evaluated by two investigators for three different aspects. The median (range) improvement of the VAS pain score was: 3 (1-6) at 6 months, 3 (2-8) at 12 months, and 4 (2-8) at 18 months. The median (range) improvement of the NDI score was: 12 (2-34) at 6 months, 18 (4-46) at 12 months, and 22 (2-44) at 18 months. Complete radiographic fusion was reached by 126 patients (43%) at 6 months, 214 patients (73%) at 12 months, and 241 patients (83%) at 18 months. Radiographic fusion was a highly significant ( p  PEEK cages is slow and insufficient. Lack of complete radiographic fusion leads to less improvement of pain and disability. We recommend against using empty uncoated pure PEEK cages in ACDF. ISRCTN42774128. Retrospectively registered 14 April 2009.

  5. Professional development to differentiate kindergarten Tier 1 instruction: Can already effective teachers improve student outcomes by differentiating Tier 1 instruction? (United States)

    Otaiba, Stephanie Al; Folsom, Jessica S; Wanzek, Jeannie; Greulich, Luana; Wasche, Jessica; Schatschneider, Christopher; Connor, Carol

    Two primary purposes guided this quasi-experimental within-teacher study: (1) to examine changes from baseline through two years of professional development (Individualizing Student Instruction) in kindergarten teachers' differentiation of Tier 1 literacy instruction; (2) to examine changes in reading and vocabulary of three cohorts of the teachers' students ( n = 416). Teachers' instruction was observed and students were assessed on standardized measures of vocabulary and word reading. Results suggested that teachers significantly increased their differentiation and students showed significantly greater word reading outcomes relative to baseline. No change was observed for vocabulary. Results have implications for supporting teacher effectiveness through technology-supported professional development.

    Weyerstraß, Jan; Prediger, Barbara; Neugebauer, Edmund; Pieper, Dawid


    Although legally anchored, there are no empirical results from German second opinion programs. In this study, various aspects within a population of a second opinion program are examined. In this study patients were analyzed who sought a second opinion in the period from August 2011 to December 2016. Differences in patient characteristics, differentiated by agreement of first and second opinion, were analyzed using multivariate logistic regression. Patients' satisfaction and quality of life were examined one, three and six months after obtaining the second opinion. In total, 1,414 patients sought a second opinion. Most frequent medical indications were the knee (38.7 %), the back (26.8 %), the hip (11.7 %), and the shoulder (10.2 %). Except for the indication (p=0.035), no patient characteristic had influence on the conformation of the second opinion. Approximately two out of three initial recommendations were not confirmed by the specialists. 89 % of the patients were satisfied or very satisfied with the second opinion and the service offered. The second opinion offers patients the opportunity to seek an additional independent medical opinion and thus provide support for decision making. Further research is needed to examine the reasons for the high discrepancies between the first and second opinions. Copyright © 2018. Published by Elsevier GmbH.

  16. Ethics instruction in the dental hygiene curriculum. (United States)

    Kacerik, Mark G; Prajer, Renee G; Conrad, Cynthia


    Dental hygiene ethics is an essential component of the dental hygiene curriculum. The accreditation standards for dental hygiene education state that graduates must be competent in applying ethical concepts to the provision and/or support of oral health care services. Although the standards for entry into the profession of dental hygiene emphasize the importance of ethical reasoning, there is little published research specific to ethics instruction in dental hygiene programs. The purpose of this study was to assess how ethics is taught in the dental hygiene curriculum. A 17-item survey was designed and distributed to 261 accredited dental hygiene programs in the United States for a response rate of 56% (N=147). The survey requested that participants provide information on teaching and evaluation methodologies, didactic and clinical hours of instruction, individuals responsible for providing instruction, and the degree of emphasis placed on ethics and integration of ethical reasoning within the dental hygiene curriculum. Results of the survey reflect that dental hygiene programs devote a mean of 20. hours to teaching dental hygiene ethics in the didactic component of the curriculum. With regard to the clinical component of the curriculum, 63% of respondents indicated that 10 or less hours are devoted to ethics instruction. These results show an increase in didactic hours of instruction from previous studies where the mean hours of instruction ranged from 7 to 11.7 hours. Results showed 64% of respondents offered a separate course in ethics; however, 82% of programs surveyed indicated that ethics was incorporated into one or more dental hygiene courses with 98% utilizing dental hygiene faculty to provide instruction. Most programs utilized a variety of instructional methods to teach ethics with the majority employing class discussion and lecture (99% and 97% respectively). The type of institution-technical college, community college, four-year university with a

  17. Instructional decision making of high school science teachers (United States)

    Carver, Jeffrey S.

    The instructional decision-making processes of high school science teachers have not been well established in the literature. Several models for decision-making do exist in other teaching disciplines, business, computer game programming, nursing, and some fields of science. A model that incorporates differences in science teaching that is consistent with constructivist theory as opposed to conventional science teaching is useful in the current climate of standards-based instruction that includes an inquiry-based approach to teaching science. This study focuses on three aspects of the decision-making process. First, it defines what factors, both internal and external, influence high school science teacher decision-making. Second, those factors are analyzed further to determine what instructional decision-making processes are articulated or demonstrated by the participants. Third, by analyzing the types of decisions that are made in the classroom, the classroom learning environments established as a result of those instructional decisions are studied for similarities and differences between conventional and constructivist models. While the decision-making process for each of these teachers was not clearly articulated by the teachers themselves, the patterns that establish the process were clearly exhibited by the teachers. It was also clear that the classroom learning environments that were established were, at least in part, established as a result of the instructional decisions that were made in planning and implementation of instruction. Patterns of instructional decision-making were different for each teacher as a result of primary instructional goals that were different for each teacher. There were similarities between teachers who exhibited more constructivist epistemological tendencies as well as similarities between teachers who exhibited a more conventional epistemology. While the decisions that will result from these two camps may be different, the six step

  19. How explicit and implicit test instructions in an implicit learning task affect performance.

    Directory of Open Access Journals (Sweden)

    Arnaud Witt

    Full Text Available Typically developing children aged 5 to 8 years were exposed to artificial grammar learning. Following an implicit exposure phase, half of the participants received neutral instructions at test while the other half received instructions making a direct, explicit reference to the training phase. We first aimed to assess whether implicit learning operated in the two test conditions. We then evaluated the differential impact of age on learning performances as a function of test instructions. The results showed that performance did not vary as a function of age in the implicit instructions condition, while age effects emerged when explicit instructions were employed at test. However, performance was affected differently by age and the instructions given at test, depending on whether the implicit learning of short or long units was assessed. These results suggest that the claim that the implicit learning process is independent of age needs to be revised.

    Vladescu, Jason C; Carroll, Regina; Paden, Amber; Kodak, Tiffany M


    The present study replicates and extends previous research on the use of video modeling (VM) with voiceover instruction to train staff to implement discrete-trial instruction (DTI). After staff trainees reached the mastery criterion when teaching an adult confederate with VM, they taught a child with a developmental disability using DTI. The results showed that the staff trainees' accurate implementation of DTI remained high, and both child participants acquired new skills. These findings provide additional support that VM may be an effective method to train staff members to conduct DTI.

  5. Taxonomy of instructions given to residents in laparoscopic cholecystectomy. (United States)

    Feng, Yuanyuan; Wong, Christopher; Park, Adrian; Mentis, Helena


    Although simulation-based training allows residents to become proficient in surgical skills outside the OR, residents still depend on senior surgeons' guidance in transferring skills accumulated from simulators into the operating room. This study aimed to identify and classify explicit instructions made by attending surgeons to their residents during laparoscopic surgery. Through these instructions, we examined the role gaze guidance plays in OR-based training. A total of ten laparoscopic cholecystectomy cases being performed by PGY4 residents were analyzed. The explicit directional instructions given by the mentoring attending surgeons to their residents were identified and classified into four categories based on their locations in the coordinate system. These categories were further combined into two classes, based on the target of instructions. The frequencies of instructions in the two classes were compared, and effect size was calculated. There were 1984 instructions identified in the ten cases. The instructions were categorized into instrument guidance (38.51%) and gaze guidance (61.49%). The instrument guidance focused on moving the instruments to perform surgical tasks, including directions to targets, instrument manipulation, and instrument interaction. The gaze guidance focused on achieving common ground during the operation, including target identification and target fixation. The frequency of gaze guidance is significantly higher than instrument guidance in a laparoscopic cholecystectomy (p guidance has become the main focus of OR-based training. The results show a tight connection between adopting expert gaze and performing surgical tasks and suggest that gaze training should be integrated into the simulation training.

  10. Effects of different forms of physiology instruction on the development of students' conceptions of and approaches to science learning. (United States)

    Lin, Yi-Hui; Liang, Jyh-Chong; Tsai, Chin-Chung


    The purpose of this study was to investigate students' conceptions of and approaches to learning science in two different forms: internet-assisted instruction and traditional (face-to-face only) instruction. The participants who took part in the study were 79 college students enrolled in a physiology class in north Taiwan. In all, 46 of the participants were from one class and 33 were from another class. Using a quasi-experimental research approach, the class of 46 students was assigned to be the "internet-assisted instruction group," whereas the class of 33 students was assigned to be the "traditional instruction group." The treatment consisted of a series of online inquiry activities. To explore the effects of different forms of instruction on students' conceptions of and approaches to learning science, two questionnaires were administered before and after the instruction: the Conceptions of Learning Science Questionnaire and the Approaches to Learning Science Questionnaire. Analysis of covariance results revealed that the students in the internet-assisted instruction group showed less agreement than the traditional instruction group in the less advanced conceptions of learning science (such as learning as memorizing and testing). In addition, the internet-assisted instruction group displayed significantly more agreement than the traditional instruction group in more sophisticated conceptions (such as learning as seeing in a new way). Moreover, the internet-assisted instruction group expressed more orientation toward the approaches of deep motive and deep strategy than the traditional instruction group. However, the students in the internet-assisted instruction group also showed more surface motive than the traditional instruction group did.

    Full Text Available Utilizing digital technology as a medium for educational instruction has now become one of the 21 century pedagogy trends. Numerous researches suggested that using digital technology provides positive impacts as it gives more access to resources for the learning. In Foreign language pedagogy, using digital technology fosters learners’ autonomy by self-managing the amount of learning inputs outside the classroom. However, many studies emphasize more on the communicative and the vast resources accessible for the learners. Very limited attention given to the impact of the visual aid that focuses on aesthetic values of instructional design. English Grammar is one of many subjects that often received complaints by learners and claimed as a “boring” subject. Many English teachers especially in developing countries still utilize traditional method in teaching grammar. They introduce sentence structure using grammar formulas. Although, this method is still very popular, it often considered monotonous by many learners. This paper discusses about the study of using presentation to deliver grammar instruction materials in an English language classroom. From the study, it was found that the majority of the students involved in the study are fond of the materials and the post-test results showed grammar mastery improvement after receiving a grammar lesson that shows instructional materials using prezi. On the other hand, the control class that uses only writing boards and worksheets showed less improvement. This research provides new technique in developing grammar instruction design using a web tool called Prezi in enhancing the display of the instruction material. The experiment was given to students of English Language Education. The result of the study shows students’ positive perception toward the use of Prezi in English grammar instructional material.

    Directory of Open Access Journals (Sweden)

    Franklin T. Thompson


    Full Text Available The reason why the Trayvon Martin murder trial and similar court cases create a philosophical rift in our nation is due in part to flaws in the delivery of multicultural education. Traditional multicultural instruction does not prepare citizens for the subtleties and complexities of race relations. This study investigates critical strategies and practices that address multicultural missing gaps. I also seek to fill a void in the literature created by a lack of student input regarding teaching strategies that encourage lifelong learning. Students (N = 337 enrolled at a Midwestern university were asked to rate the efficacy of selected instructional strategies. Utilizing a 9-point Likert-type scale, students gave themselves a personal growth rating of 7.15 (SD = 1.47. Variables important to predicting that growth (R2 = .56, p < .0005 were a six-factor variable known as a non-color-blind instructional approach (t = 10.509, p ≤ .0005, allowing students an opportunity to form their own opinions apart from the instructor (t = 4.797, p ≤ .0005, and a state law that mandated multicultural training (t = 3.234, p = .001. Results demonstrated that utilizing a 35% traditional and 65% critical pedagogy mixture when teaching multicultural education helped promote win/win scenarios for education candidates hoping to become difference makers.

  18. Death Penalty Decisions: Instruction Comprehension, Attitudes, and Decision Mediators. (United States)

    Patry, Marc W; Penrod, Steven D


    A primary goal of this research was to empirically evaluate a set of assumptions, advanced in the Supreme Court's ruling in Buchanan v. Angelone (1998), about jury comprehension of death penalty instructions. Further, this research examined the use of evidence in capital punishment decision making by exploring underlying mediating factors upon which death penalty decisions may be based. Manipulated variables included the type of instructions and several variations of evidence. Study 1 was a paper and pencil study of 245 undergraduate mock jurors. The experimental design was an incomplete 4×2×2×2×2 factorial model resulting in 56 possible conditions. Manipulations included four different types of instructions, presence of a list of case-specific mitigators to accompany the instructions, and three variations in the case facts: age of the defendant, bad prior record, and defendant history of emotional abuse. Study 2 was a fully-crossed 2×2×2×2×2 experiment with four deliberating mock juries per cell. Manipulations included jury instructions (original or revised), presence of a list of case-specific mitigators, defendant history of emotional abuse, bad prior record, and heinousness of the crime. The sample of 735 jury-eligible participants included 130 individuals who identified themselves as students. Participants watched one of 32 stimulus videotapes based on a replication of a capital sentencing hearing. The present findings support previous research showing low comprehension of capital penalty instructions. Further, we found that higher instruction comprehension was associated with higher likelihood of issuing life sentence decisions. The importance of instruction comprehension is emphasized in a social cognitive model of jury decision making at the sentencing phase of capital cases.

    Full Text Available The goal of the research was to compare the level of mathematic language acquisition between students of lower grades in special elementary schools for children who are hearing impaired and students of a mainstream elementary school. A total of 239 children attending mainstream and special schools in the territory of Serbia were included in the research. Instruction of mathematics in schools for students who are hearing impaired has a different character as it contains elements of native language instruction. Obtained results show a significant difference in some fields. A conclusion stating that the level of language acquisition is in direct correlation with the level of acquisition of mathematics language imposes itself. What that means is that hearing impaired children have not only to comprehend mathematics relations, but also to learn mathematics terms in a completely different way as compared to children who are hearing.

    A sample of 49 non-psychology majors taking a course integrating library research skills with social science research showed increases in skill level, efficiency, and positive attitudes toward the library after a semester of outcome-focused instruction. The results suggest that co-development between course and library faculty can be an effective…

  1. Verbal-motor attention-focusing instructions influence kinematics and performance on a golf-putting task. (United States)

    Munzert, Jörn; Maurer, Heiko; Reiser, Mathias


    The authors examined how varying the content of verbal-motor instructions and requesting an internal versus external focus influenced the kinematics and outcome of a golf putting task. On Day 1, 30 novices performed 120 trials with the instruction to focus attention either on performing a pendulum-like movement (internal) or on the desired ball path (external). After 20 retention trials on Day 2, they performed 20 transfer trials with the opposite instruction. Group differences for retention and a group by block interaction showed that external instruction enhanced movement outcome. Kinematic data indicated that specific instruction content influenced outcomes by eliciting changes in movement execution. Switching from the external to the internal focus instruction resulted in a more pendulum-like movement.

  2. Spanish Instruction in Head Start and Dual Language Learners' Academic Achievement. (United States)

    Miller, Elizabeth B


    Data from the Head Start Impact Study ( N = 1,141) and the Head Start Family and Child Experiences Survey, 2009 Cohort ( N = 825) were used to investigate whether Spanish instruction in Head Start differentially increased Spanish-speaking Dual Language Learners' (DLLs) academic achievement. Although hypothesized that Spanish instruction would be beneficial for DLLs' early literacy and math skills, results from residualized growth models showed there were no such positive associations. Somewhat surprisingly, DLL children instructed in Spanish had higher English receptive vocabulary skills at the end of the Head Start year than those not instructed, with children randomly assigned to Head Start and instructed in Spanish having the highest scores. Policy implications for Head Start-eligible Spanish-speaking DLLs are discussed.

  3. Does systematic reading instruction impede prediction of reading a shallow orthography?

    Directory of Open Access Journals (Sweden)



    Full Text Available Different methods of reading instructions have been the subject of controversy. This study examined the influence of systematic phonics vs. non-systematic phonics methods of instruction on the prediction of reading. 443 kindergarten children were tested on phonological awareness, naming speed and visual word matching using the Bielefelder Screening (BISC. Children were retested in grades one and four. Results showed that although the prognostic validity of kindergarten measures was generally low, it was considerably higher for grade one children in classes with non-systematic phonics instruction. Children who received systematic phonics instruction scored significantly higher on measures of phonological decoding as compared to their peers who received less systematic instruction. Implications for the prediction of reading and early screenings are discussed.

    Full Text Available This study aims at contributing to the investigation on the instruction of EST (English for Science and Technology vocabulary, in terms of receptive use of the language. It evaluates the effectiveness of two teaching approaches to the acquisition of vocabulary. The first approach consisted of teaching vocabulary through the use of dictionaries, where the words were merely translated into the learners’ L1 or defined in the target language thus promoting superficial level of word processing. The second approach employed activities promoting deep level of word processing. Data were analysed quantitatively. Results indicated that the two approaches seem to have some equipotentiality, as far as EST vocabulary is concerned.

  10. Review of Instructional Approaches in Ethics Education. (United States)

    Mulhearn, Tyler J; Steele, Logan M; Watts, Logan L; Medeiros, Kelsey E; Mumford, Michael D; Connelly, Shane


    Increased investment in ethics education has prompted a variety of instructional objectives and frameworks. Yet, no systematic procedure to classify these varying instructional approaches has been attempted. In the present study, a quantitative clustering procedure was conducted to derive a typology of instruction in ethics education. In total, 330 ethics training programs were included in the cluster analysis. The training programs were appraised with respect to four instructional categories including instructional content, processes, delivery methods, and activities. Eight instructional approaches were identified through this clustering procedure, and these instructional approaches showed different levels of effectiveness. Instructional effectiveness was assessed based on one of nine commonly used ethics criteria. With respect to specific training types, Professional Decision Processes Training (d = 0.50) and Field-Specific Compliance Training (d = 0.46) appear to be viable approaches to ethics training based on Cohen's d effect size estimates. By contrast, two commonly used approaches, General Discussion Training (d = 0.31) and Norm Adherence Training (d = 0.37), were found to be considerably less effective. The implications for instruction in ethics training are discussed.

Evidence-based practice is not about the survival of school librarians, it’s about the survival of our students” (40. In this issue we feature school libraries and their connection to evidence based practice. Former Editor-in-Chief, Lindsay Glynn, began putting the wheels in motion for this feature almost a year ago. She invited Carol Gordon and Ross Todd to act as guest editors of the section, drawing upon their contacts and previous work in this field. The result is an issue with five feature articles exploring different aspects of the connection between school libraries and evidence based practice, from the theoretical to the practical. In addition, there is a thought-provoking Commentary by David Loertscher, asking whether we need the evolutionary model of evidence based practice, or something more revolutionary!In addition to the Feature section, we have a well-rounded issue with articles on the topics of library human resources, and the development of a scholars’ portal. As well, there are a record 10 evidence summaries and our educational EBL101 column. I hope there is something for everyone in this issue of EBLIP – enjoy, and see you soon in Stockholm!

  12. A comparison of automatic and intentional instructions when using the method of vanishing cues in acquired brain injury. (United States)

    Riley, Gerard A; Venn, Paul


    Thirty-four participants with acquired brain injury learned word lists under two forms of vanishing cues - one in which the learning trial instructions encouraged intentional retrieval (i.e., explicit memory) and one in which they encouraged automatic retrieval (which encompasses implicit memory). The automatic instructions represented a novel approach in which the cooperation of participants was actively sought to avoid intentional retrieval. Intentional instructions resulted in fewer errors during the learning trials and better performance on immediate and delayed retrieval tests. The advantage of intentional over automatic instructions was generally less for those who had more severe memory and/or executive impairments. Most participants performed better under intentional instructions on both the immediate and the delayed tests. Although those who were more severely impaired in both memory and executive function also did better with intentional instructions on the immediate retrieval test, they were significantly more likely to show an advantage for automatic instructions on the delayed test. It is suggested that this pattern of results may reflect impairments in the consolidation of intentional memories in this group. When using vanishing cues, automatic instructions may be better for those with severe consolidation impairments, but otherwise intentional instructions may be better.

  17. Ultrasonography-guided core needle biopsy for the thyroid nodule: does the procedure hold any benefit for the diagnosis when fine-needle aspiration cytology analysis shows inconclusive results? (United States)

    Hahn, S Y; Han, B-K; Ko, E Y; Ko, E S


    Objective: We evaluated the diagnostic role of ultrasonography-guided core needle biopsy (CNB) according to ultrasonography features of thyroid nodules that had inconclusive ultrasonography-guided fine-needle aspiration (FNA) results. Methods: A total of 88 thyroid nodules in 88 patients who underwent ultrasonography-guided CNB because of previous inconclusive FNA results were evaluated. The patients were classified into three groups based on ultrasonography findings: Group A, which was suspicious for papillary thyroid carcinoma (PTC); Group B, which was suspicious for follicular (Hurthle cell) neoplasm; and Group C, which was suspicious for lymphoma. The final diagnoses of the thyroid nodules were determined by surgical confirmation or follow-up after ultrasonography-guided CNB. Results: Of the 88 nodules, the malignant rate was 49.1% in Group A, 12.0% in Group B and 90.0% in Group C. The rates of conclusive ultrasonography-guided CNB results after previous incomplete ultrasonography-guided FNA results were 96.2% in Group A, 64.0% in Group B and 90.0% in Group C (p=0.001). 12 cases with inconclusive ultrasonography-guided CNB results were finally diagnosed as 8 benign lesions, 3 PTCs and 1 lymphoma. The number of previous ultrasonography-guided FNA biopsies was not significantly different between the conclusive and the inconclusive result groups of ultrasonography-guided CNB (p=0.205). Conclusion: Ultrasonography-guided CNB has benefit for the diagnosis of thyroid nodules with inconclusive ultrasonography-guided FNA results. However, it is still not helpful for the differential diagnosis in 36% of nodules that are suspicious for follicular neoplasm seen on ultrasonography. Advances in knowledge: This study shows the diagnostic contribution of ultrasonography-guided CNB as an alternative to repeat ultrasonography-guided FNA or surgery. PMID:23564885

  20. Obesity in show cats. (United States)

    Corbee, R J


    Obesity is an important disease with a high prevalence in cats. Because obesity is related to several other diseases, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain cat breeds has been suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, 268 cats of 22 different breeds investigated by determining their body condition score (BCS) on a nine-point scale by inspection and palpation, at two different cat shows. Overall, 45.5% of the show cats had a BCS > 5, and 4.5% of the show cats had a BCS > 7. There were significant differences between breeds, which could be related to the breed standards. Most overweight and obese cats were in the neutered group. It warrants firm discussions with breeders and cat show judges to come to different interpretations of the standards in order to prevent overweight conditions in certain breeds from being the standard of beauty. Neutering predisposes for obesity and requires early nutritional intervention to prevent obese conditions. Journal of Animal Physiology and Animal Nutrition © 2014 Blackwell Verlag GmbH.

  2. Children's Learning in Scientific Thinking: Instructional Approaches and Roles of Variable Identification and Executive Function (United States)

    Blums, Angela

    The present study examines instructional approaches and cognitive factors involved in elementary school children's thinking and learning the Control of Variables Strategy (CVS), a critical aspect of scientific reasoning. Previous research has identified several features related to effective instruction of CVS, including using a guided learning approach, the use of self-reflective questions, and learning in individual and group contexts. The current study examined the roles of procedural and conceptual instruction in learning CVS and investigated the role of executive function in the learning process. Additionally, this study examined how learning to identify variables is a part of the CVS process. In two studies (individual and classroom experiments), 139 third, fourth, and fifth grade students participated in hands-on and paper and pencil CVS learning activities and, in each study, were assigned to either a procedural instruction, conceptual instruction, or control (no instruction) group. Participants also completed a series of executive function tasks. The study was carried out with two parts--Study 1 used an individual context and Study 2 was carried out in a group setting. Results indicated that procedural and conceptual instruction were more effective than no instruction, and the ability to identify variables was identified as a key piece to the CVS process. Executive function predicted ability to identify variables and predicted success on CVS tasks. Developmental differences were present, in that older children outperformed younger children on CVS tasks, and that conceptual instruction was slightly more effective for older children. Some differences between individual and group instruction were found, with those in the individual context showing some advantage over the those in the group setting in learning CVS concepts. Conceptual implications about scientific thinking and practical implications in science education are discussed.

  3. Intelligence moderates the benefits of strategy instructions on memory performance: an adult-lifespan examination. (United States)

    Frankenmolen, Nikita L; Altgassen, Mareike; Kessels, Renée; de Waal, Marleen M; Hindriksen, Julie-Anne; Verhoeven, Barbara; Fasotti, Luciano; Scheres, Anouk; Kessels, Roy P C; Oosterman, Joukje M


    Whether older adults can compensate for their associative memory deficit by using memory strategies efficiently might depend on their general cognitive abilities. This study examined the moderating role of an IQ estimate on the beneficial effects of strategy instructions. A total of 142 participants (aged 18-85 years) received either intentional learning or strategy ("sentence generation") instructions during encoding of word pairs. Whereas young adults with a lower IQ benefited from strategy instructions, those with a higher IQ did not, presumably because they already use strategies spontaneously. Older adults showed the opposite effect: following strategy instructions, older adults with a higher IQ showed a strong increase in memory performance (approximately achieving the level of younger adults), whereas older adults with a lower IQ did not, suggesting that they have difficulties implementing the provided strategies. These results highlight the importance of the role of IQ in compensating for the aging-related memory decline.

  5. Scientific reasoning during adolescence: The influence of instruction in science knowledge and reasoning strategies (United States)

    Linn, M. C.; Clement, C.; Pulos, S.; Sullivan, P.

    The mechanism linking instruction in scientific topics and instruction in logical reasoning strategies is not well understood. This study assesses the role of science topic instruction combined with logical reasoning strategy instruction in teaching adolescent students about blood pressure problems. Logical reasoning instruction for this study emphasizes the controlling-variables strategy. Science topic instruction emphasizes variables affecting blood pressure. Subjects receiving logical reasoning instruction link their knowledge of blood pressure variables to their knowledge of controlling variables more effectively than those receiving science topic instruction alone - their specific responses show how they attempt to integrate their understanding.Received: 15 April 1988

  9. Effective instruction for English learners. (United States)

    Calderón, Margarita; Slavin, Robert; Sánchez, Marta


    The fastest-growing student population in U.S. schools today is children of immigrants, half of whom do not speak English fluently and are thus labeled English learners. Although the federal government requires school districts to provide services to English learners, it offers states no policies to follow in identifying, assessing, placing, or instructing them. Margarita Calderón, Robert Slavin, and Marta Sánchez identify the elements of effective instruction and review a variety of successful program models. During 2007-08, more than 5.3 million English learners made up 10.6 percent of the nation's K-12 public school enrollment. Wide and persistent achievement disparities between these English learners and English-proficient students show clearly, say the authors, that schools must address the language, literacy, and academic needs of English learners more effectively. Researchers have fiercely debated the merits of bilingual and English-only reading instruction. In elementary schools, English learners commonly receive thirty minutes of English as a Second Language (ESL) instruction but attend general education classes for the rest of the day, usually with teachers who are unprepared to teach them. Though English learners have strikingly diverse levels of skills, in high school they are typically lumped together, with one teacher to address their widely varying needs. These in-school factors contribute to the achievement disparities. Based on the studies presented here, Calderón, Slavin, and Sánchez assert that the quality of instruction is what matters most in educating English learners. They highlight comprehensive reform models, as well as individual components of these models: school structures and leadership; language and literacy instruction; integration of language, literacy, and content instruction in secondary schools; cooperative learning; professional development; parent and family support teams; tutoring; and monitoring implementation and outcomes

    Full Text Available Abstract Background Since Fuchs' report in 1999, the reported protective effect of dietary fiber from colorectal carcinogenesis has led many researchers to question its real benefit. The aim of this study is to evaluate the association between diet, especially dietary fiber and fat and colorectal cancer in Japan. Methods A multiple regression analysis (using the stepwise variable selection method was performed using the standardized mortality ratios (SMRs of colon and rectal cancer in 23 Japanese prefectures as objective variables and dietary fiber, nutrients and food groups as explanatory variables. Results As for colon cancer, the standardized partial correlation coefficients were positively significant for fat (1,13, P = 0.000, seaweeds (0.41, P = 0.026 and beans (0.45, P = 0.017 and were negatively significant for vitamin A (-0.63, P = 0.003, vitamin C (-0.42, P = 0.019 and yellow-green vegetables (-0.37, P = 0.046. For rectal cancer, the standardized partial correlation coefficient in fat (0.60, P = 0.002 was positively significant. Dietary fiber was not found to have a significant relationship with either colon or rectal cancers. Conclusions This study failed to show any protective effect of dietary fiber in subjects with a low fat intake (Japanese in this analysis, which supports Fuchs' findings in subjects with a high fat intake (US Americans.

  12. The Value of Supplementing Science Education with Outdoor Instruction for Sixth Grade Students (United States)

    Jackson, Devin Joseph Guilford

    Science education is moving away from memorization of facts to inquiry based learning. Adding outdoor instruction can be an effective way to promote this exploratory method of learning. The limited number of empirical studies available have shown significant increase in attitudes and learning with outdoor science instruction. An eight-week quasi-experimental teacher research study was conducted to further this research and assess the value of schoolyard science instruction on student engagement and learning. Participants were 60 students in two sixth grade middle school Earth Science classes. A crossover study design was used with two classes alternating as experimental and control groups. NASA Global Precipitation Measurement mission curriculum was used (NASA/GPM, 2011). While the results did not show a clear increase in student engagement and content knowledge, the study adds to the body of knowledge on outdoor instruction and identifies limitations to consider in future studies.

  13. Effectiveness of Case-Based Learning Instruction on Epistemological Beliefs and Attitudes Toward Chemistry (United States)

    Çam, Aylin; Geban, Ömer


    The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students' epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students' epistemological beliefs and attitudes toward chemistry.

    Full Text Available The prime purpose of this study was to explore a correlation between bilingual instruction in an ESL class and the class performance of the ESL learners at the secondary level. Quantitative research method was used to evaluate the test performance of 60 ESL learners divided into two groups: One was the controlled group (which was given instructions in L2 only and the other was the treatment group (which was given instructions in both L1 and L2 in Public School settings. Apart from the students, 15 language teachers’ feedback upon their perceptions of L1 usage in L2 classrooms was taken by using the Likert scale feedback forms. The results confirmed that the instructions given bilingually are directly associated to improved learner outcomes and teachers’ responses for the usage of L1 in classrooms showed a strong positive response.

  15. Urban school leadership for elementary science instruction: Identifying and activating resources in an undervalued school subject (United States)

    Spillane, James P.; Diamond, John B.; Walker, Lisa J.; Halverson, Rich; Jita, Loyiso


    This article explores school leadership for elementary school science teaching in an urban setting. We examine how school leaders bring resources together to enhance science instruction when there appear to be relatively few resources available for it. From our study of 13 Chicago elementary (K-8) schools' efforts to lead instructional change in mathematics, language arts, and science education, we show how resources for leading instruction are unequally distributed across subject areas. We also explore how over time leaders in one school successfully identified and activated resources for leading change in science education. The result has been a steady, although not always certain, development of science as an instructional area in the school. We argue that leading change in science education involves the identification and activation of material resources, the development of teachers' and school leaders' human capital, and the development and use of social capital.

  16. Children's learning of tennis skills is facilitated by external focus instructions

    Directory of Open Access Journals (Sweden)

    Ricardo Hadler


    Full Text Available The present study examined the effects of instructions promoting external versus internal foci of attention on the learning of a tennis forehand stroke in 11-year old children. Three groups of participants practiced hitting tennis balls at a target. External focus group participants were instructed to direct their attention to the movement of the racquet, while participants in the internal focus group were asked to direct their attention to the movements of their arm. Participants in a control group did not receive attentional focus instructions. Two days after the practice phase (60 trials, learning was assessed in retention and transfer tests. The results showed that the external focus group demonstrated greater accuracy in hitting a target relative to the two other groups in retention, and relative to the internal focus group in transfer. We conclude that instructions inducing an external focus of attention can enhance children's sport skill learning.

  18. Proportion congruency effects: Instructions may be enough

    Directory of Open Access Journals (Sweden)

    Olga eEntel


    Full Text Available Learning takes time, namely, one needs to be exposed to contingency relations between stimulus dimensions in order to learn, whereas intentional control can be recruited through task demands. Therefore showing that control can be recruited as a function of experimental instructions alone, that is, adapting the processing according to the instructions before the exposure to the task, can be taken as evidence for existence of control recruitment in the absence of learning. This was done by manipulating the information given at the outset of the experiment. In the first experiment, we manipulated list-level congruency proportion. Half of the participants were informed that most of the stimuli would be congruent, whereas the other half were informed that most of the stimuli would be incongruent. This held true for the stimuli in the second part of each experiment. In the first part, however, the proportion of the two stimulus types was equal. A proportion congruent effect was found in both parts of the experiment, but it was larger in the second part. In our second experiment, we manipulated the proportion of the stimuli within participants by applying an item-specific design. This was done by presenting some color words most often in their congruent color, and other color words in incongruent colors. Participants were informed about the exact word-color pairings in advance. Similar to Experiment 1, this held true only for the second experimental part. In contrast to our first experiment, informing participants in advance did not result in an item-specific proportion effect, which was observed only in the second part. Thus our results support the hypothesis that instructions may be enough to trigger list-level control, yet learning does contribute to the proportion congruent effect under such conditions. The item-level proportion effect is apparently caused by learning or at least it is moderated by it.

  20. Learning, awareness, and instruction: subjective contingency awareness does matter in the colour-word contingency learning paradigm. (United States)

    Schmidt, James R; De Houwer, Jan


    In three experiments, each of a set colour-unrelated distracting words was presented most often in a particular target print colour (e.g., "month" most often in red). In Experiment 1, half of the participants were told the word-colour contingencies in advance (instructed) and half were not (control). The instructed group showed a larger learning effect. This instruction effect was fully explained by increases in subjective awareness with instruction. In Experiment 2, contingency instructions were again given, but no contingencies were actually present. Although many participants claimed to be aware of these (non-existent) contingencies, they did not produce an instructed contingency effect. In Experiment 3, half of the participants were given contingency instructions that did not correspond to the correct contingencies. Participants with these false instructions learned the actual contingencies worse than controls. Collectively, our results suggest that conscious contingency knowledge might play a moderating role in the strength of implicit learning. Copyright © 2012 Elsevier Inc. All rights reserved.

    Problem-solving can be facilitated with instructions or hints, which provide information about given problems. The proper amount of instruction that should be provided for learners is controversial. Research shows that tasks with intermediate difficulty induce the largest sense of accomplishment (SA), leading to an intrinsic motivation for learning. To investigate the effect of instructions, we prepared three instruction levels (No hint, Indirect hint, and Direct hint) for the same insight-problem types. We hypothesized that indirect instructions impose intermediate difficulty for each individual, thereby inducing the greatest SA per person. Based on previous neuroimaging studies that showed involvement of the bilateral caudate in learning and motivation, we expected SA to be processed in this reward system. We recruited twenty-one participants, and investigated neural activations during problem solving by functional magnetic resonance imaging (fMRI). We confirmed that the Indirect hint, which imposed intermediate difficulty, induced the largest SA among the three instruction types. Using fMRI, we showed that activations in the bilateral caudate and anterior cingulate cortex (ACC) were significantly modulated by SA. In the bilateral caudate, the indirect hint induced the largest activation, while the ACC seemed to reflect the difference between correct and incorrect trials. Importantly, such activation pattern was independent of notations (number or letter). Our results indicate that SA is represented in the reward system, and that the Indirect instruction effectively induces such sensation.

  4. Collaboration Mechanism for Equipment Instruction of Multiple Energy Systems (United States)

    Wang, Dong; Wang, Tuo; Wang, Qi; Zhang, Zhao; Zhao, Mingyu; Wang, Yinghui


    When multiple energy systems execute optimization instructions simultaneously, and the same equipment is Shared, the instruction conflict may occur. Aiming at the above problems, taking into account the control objectives of each system, the characteristics of different systems, such as comprehensive clean energy, energy efficiency, and peak filling, etc., designed the instruction coordination mechanism for the daemon. This mechanism mainly acts on the main station of the system, and form a final optimization instruction. For some specific scenarios, the collaboration mechanism of unlocking the terminal is supplemented. The mechanism determines the specific execution instructions based on the arrival time of the instruction. Finally, the experiment in Tianjin eco-city shows that this algorithm can meet the instruction and collaboration requirements of multi-energy systems, and ensure the safe operation of the equipment.

  5. Differentiating Science Instruction: Secondary science teachers' practices (United States)

    Maeng, Jennifer L.; Bell, Randy L.


    This descriptive study investigated the implementation practices of secondary science teachers who differentiate instruction. Participants included seven high school science teachers purposefully selected from four different schools located in a mid-Atlantic state. Purposeful selection ensured participants included differentiated instruction (DI) in their lesson implementation. Data included semi-structured interviews and field notes from a minimum of four classroom observations, selected to capture the variety of differentiation strategies employed. These data were analyzed using a constant-comparative approach. Each classroom observation was scored using the validated Differentiated Instruction Implementation Matrix-Modified, which captured both the extent to which critical indicators of DI were present in teachers' instruction and the performance levels at which they engaged in these components of DI. Results indicated participants implemented a variety of differentiation strategies in their classrooms with varying proficiency. Evidence suggested all participants used instructional modifications that required little advance preparation to accommodate differences in students' interests and learning profile. Four of the seven participants implemented more complex instructional strategies that required substantial advance preparation by the teacher. Most significantly, this study provides practical strategies for in-service science teachers beginning to differentiate instruction and recommendations for professional development and preservice science teacher education.

  8. Automatic Retrieval of Newly Instructed Cue-Task Associations Seen in Task-Conflict Effects in the First Trial after Cue-Task Instructions. (United States)

    Meiran, Nachshon; Pereg, Maayan


    Novel stimulus-response associations are retrieved automatically even without prior practice. Is this true for novel cue-task associations? The experiment involved miniblocks comprising three phases and task switching. In the INSTRUCTION phase, two new stimuli (or familiar cues) were arbitrarily assigned as cues for up-down/right-left tasks performed on placeholder locations. In the UNIVALENT phase, there was no task cue since placeholder's location afforded one task but the placeholders were the stimuli that we assigned as task cues for the following BIVALENT phase (involving target locations affording both tasks). Thus, participants held the novel cue-task associations in memory while executing the UNIVALENT phase. Results show poorer performance in the first univalent trial when the placeholder was associated with the opposite task (incompatible) than when it was compatible, an effect that was numerically larger with newly instructed cues than with familiar cues. These results indicate automatic retrieval of newly instructed cue-task associations.

  9. Computer-based instruction system DIDAK and its application

    International Nuclear Information System (INIS)

    Gvozdjak, L.; Hanulova, L.; Jankovicova, A.; Scepanek, L.


    The DIDAK system has been developed for the instruction and training of specialized personnel of nuclear power plants. The structure of the instruction system comprises three processes: the author process, the instruction process and the administration process. Author processes provide the didactic data structure with instruction texts. In the text data base the instruction material is stored in 6 direct access nonformatted files. The instruction system receives information from the text data base and presents it to the student. According to the student's response it creates the preconditions for the further operation of the system which it stores in the data base for administration of instruction. This base contains data on the identification of students, on the instruction process of the individual and the instruction process as a whole. Administrative processes take place in the final stage. They provide information on the general course of instruction and make final evaluations. From the data base of products of the instruction process the said administrative processes produce output information for the teacher. The subject matter of each subject is divided into a finite number of elementary units of subject matter. Each elementary unit provides basic information on the explained subject matter and is followed by a check of the student's knowledge. In dependence on the results of this check the student either advances to a higher level elementary unit or proceeds to an alternative branch of the initial unit. (E.S.)

  10. A re-examination of the effects of biased lineup instructions in eyewitness identification. (United States)

    Clark, Steven E


    A meta-analytic review of research comparing biased and unbiased instructions in eyewitness identification experiments showed an asymmetry; specifically, that biased instructions led to a large and consistent decrease in accuracy in target-absent lineups, but produced inconsistent results for target-present lineups, with an average effect size near zero (Steblay, 1997). The results for target-present lineups are surprising, and are inconsistent with statistical decision theories (i.e., Green & Swets, 1966). A re-examination of the relevant studies and the meta-analysis of those studies shows clear evidence that correct identification rates do increase with biased lineup instructions, and that biased witnesses make correct identifications at a rate considerably above chance. Implications for theory, as well as police procedure and policy, are discussed.

  11. The effect of instructional methodology on high school students natural sciences standardized tests scores (United States)

    Powell, P. E.

    Educators have recently come to consider inquiry based instruction as a more effective method of instruction than didactic instruction. Experience based learning theory suggests that student performance is linked to teaching method. However, research is limited on inquiry teaching and its effectiveness on preparing students to perform well on standardized tests. The purpose of the study to investigate whether one of these two teaching methodologies was more effective in increasing student performance on standardized science tests. The quasi experimental quantitative study was comprised of two stages. Stage 1 used a survey to identify teaching methods of a convenience sample of 57 teacher participants and determined level of inquiry used in instruction to place participants into instructional groups (the independent variable). Stage 2 used analysis of covariance (ANCOVA) to compare posttest scores on a standardized exam by teaching method. Additional analyses were conducted to examine the differences in science achievement by ethnicity, gender, and socioeconomic status by teaching methodology. Results demonstrated a statistically significant gain in test scores when taught using inquiry based instruction. Subpopulation analyses indicated all groups showed improved mean standardized test scores except African American students. The findings benefit teachers and students by presenting data supporting a method of content delivery that increases teacher efficacy and produces students with a greater cognition of science content that meets the school's mission and goals.

    Yuan-Cheng Chang


    Full Text Available Based on creativity component theory, creativity system theory and creative self-efficacy theory, this study aims to explore the influence of college students’ aesthetics experience and creative self-efficacy on their creativity and the role of creativity instruction as a mediator variable. The participants were 338 college design majors in 50 teams who were working on their graduation exhibitions, and 50 advising professors from departments related to design. Hierarchical Linear Models were applied for analysis. The result showed that instruction on enhancing students’ creative intention positively affect students’ aesthetics experience. Students’ aesthetics experience affects their creativity and creative self-efficacy. Creativity instruction with focus on creativity skills by means of promoting aesthetic attitude, aesthetic understanding, and offering complete experiences had a moderating effect on students’ perception toward creative product. However, there was a negative moderating effect of creative instruction on perceived aesthetic pleasure and students’ perception toward creative product. There was no moderating effect of creative instruction on the relationship between students’ creative self-efficacy and creativity. Accordingly, the study concluded that in order to enhance students’ creativity, universities should stress on the development of students’ aesthetics experiences and re-evaluation of approaches to creativity instruction.

    Suzuki, Hidenobu; Hibino, Hiroyuki; Inoue, Yuichi; Matsumoto, Hideo; Mikami, Katsunaka


    Schizophrenia is a chronic disease that requires long-term management with antipsychotics. Antipsychotic drugs are given by tapering their dose, extending the dosing interval, and so on, as part of a treatment strategy to minimize the adverse effects while at the same time maintaining efficacy. We report the case of one patient with schizophrenia in whom the clinical symptoms were alleviated after treatment with 6 mg paliperidone. However, the patient developed extrapyramidal syndrome, for which 3 and 6 mg paliperidone were administered alternately every other day. Extrapyramidal syndrome was assessed using the Drug-Induced Extrapyramidal Symptoms Scale, Abnormal Involuntary Movement Scale, or Barnes Akathisia Scale. There was improvement in Drug-Induced Extrapyramidal Symptoms Scale score and Abnormal Involuntary Movement Scale score. However, there was almost no change in the Positive and Negative Syndrome Scale total score, positive score, negative score, or general score. The results indicate the possibility of lessened adverse effects as a result of an alternative regimen of treatment with paliperidone 3 and 6 mg every other day in the maintenance phase.

  16. Preparing medical students for future learning using basic science instruction. (United States)

    Mylopoulos, Maria; Woods, Nicole


    The construct of 'preparation for future learning' (PFL) is understood as the ability to learn new information from available resources, relate new learning to past experiences and demonstrate innovation and flexibility in problem solving. Preparation for future learning has been proposed as a key competence of adaptive expertise. There is a need for educators to ensure that opportunities are provided for students to develop PFL ability and that assessments accurately measure the development of this form of competence. The objective of this research was to compare the relative impacts of basic science instruction and clinically focused instruction on performance on a PFL assessment (PFLA). This study employed a 'double transfer' design. Fifty-one pre-clerkship students were randomly assigned to either basic science instruction or clinically focused instruction to learn four categories of disease. After completing an initial assessment on the learned material, all participants received clinically focused instruction for four novel diseases and completed a PFLA. The data from the initial assessment and the PFLA were submitted to independent-sample t-tests. Mean ± standard deviation [SD] scores on the diagnostic cases in the initial assessment were similar for participants in the basic science (0.65 ± 0.11) and clinical learning (0.62 ± 0.11) conditions. The difference was not significant (t[42] = 0.90, p = 0.37, d = 0.27). Analysis of the diagnostic cases on the PFLA revealed significantly higher mean ± SD scores for participants in the basic science learning condition (0.72 ± 0.14) compared with those in the clinical learning condition (0.63 ± 0.15) (t[42] = 2.02, p = 0.05, d = 0.62). Our results show that the inclusion of basic science instruction enhanced the learning of novel related content. We discuss this finding within the broader context of research on basic science instruction, development of adaptive expertise and assessment

  18. Evaluation of real-time data obtained from gravimetric preparation of antineoplastic agents shows medication errors with possible critical therapeutic impact: Results of a large-scale, multicentre, multinational, retrospective study. (United States)

    Terkola, R; Czejka, M; Bérubé, J


    Medication errors are a significant cause of morbidity and mortality especially with antineoplastic drugs, owing to their narrow therapeutic index. Gravimetric workflow software systems have the potential to reduce volumetric errors during intravenous antineoplastic drug preparation which may occur when verification is reliant on visual inspection. Our aim was to detect medication errors with possible critical therapeutic impact as determined by the rate of prevented medication errors in chemotherapy compounding after implementation of gravimetric measurement. A large-scale, retrospective analysis of data was carried out, related to medication errors identified during preparation of antineoplastic drugs in 10 pharmacy services ("centres") in five European countries following the introduction of an intravenous workflow software gravimetric system. Errors were defined as errors in dose volumes outside tolerance levels, identified during weighing stages of preparation of chemotherapy solutions which would not otherwise have been detected by conventional visual inspection. The gravimetric system detected that 7.89% of the 759 060 doses of antineoplastic drugs prepared at participating centres between July 2011 and October 2015 had error levels outside the accepted tolerance range set by individual centres, and prevented these doses from reaching patients. The proportion of antineoplastic preparations with deviations >10% ranged from 0.49% to 5.04% across sites, with a mean of 2.25%. The proportion of preparations with deviations >20% ranged from 0.21% to 1.27% across sites, with a mean of 0.71%. There was considerable variation in error levels for different antineoplastic agents. Introduction of a gravimetric preparation system for antineoplastic agents detected and prevented dosing errors which would not have been recognized with traditional methods and could have resulted in toxicity or suboptimal therapeutic outcomes for patients undergoing anticancer treatment.

  19. Construction and reconstruction concept in mathematics instruction (United States)

    Mumu, Jeinne; Charitas Indra Prahmana, Rully; Tanujaya, Benidiktus


    The purpose of this paper is to describe two learning activities undertaken by lecturers, so that students can understand a mathematical concept. The mathematical concept studied in this research is the Vector Space in Linear Algebra instruction. Classroom Action Research used as a research method with pre-service mathematics teacher at University of Papua as the research subject. Student participants are divided into two parallel classes, 24 students in regular class, and remedial class consist of 18 students. Both approaches, construct and reconstruction concept, are implemented on both classes. The result shows that concept construction can only be done in regular class while in remedial class, learning with concept construction approach is not able to increase students' understanding on the concept taught. Understanding the concept of a student in a remedial class can only be carried out using the concept reconstruction approach.

  20. Instructional Interventions and Affective Beliefs as Predictors of Achievement and Retention of Learning

    Directory of Open Access Journals (Sweden)

    Ambrose Hans G. Aggabao


    Full Text Available Path and factor analyses were used in this study to investigate direct and indirect influences of instructional interventions on achievement and retention of learning among freshmen students in Mathematics as mediated by affective beliefs. The varying classroom contexts were hypothesized to influence affective beliefs through the application of varying instructional interventions – traditional teaching, radical constructivist, and social constructivist. The randomized equivalent groups pre-posttest experimental design was used to generate the needed data for analysis. Results showed that constructivist instructional approaches directly and indirectly influenced achievement measures with the indirect effects mediated by control orientation belief of students which was found to be the only one among four affective beliefs considered in this study to influence achievement measures. Social constructivist interventions did not show direct influence on retention of conceptual understanding and procedural fluency while traditional instructional intervention was not found to be a significant predictor of both affective beliefs and achievement measures.These results confirm for the most part the hypothesized relations among instructional interventions, affective beliefs, and achievement measures.

    Morton, M.R.


    The Bechtel Hanford, Inc. facility transition instruction was initiated in response to the need for a common, streamlined process for facility transitions and to capture the knowledge and experience that has accumulated over the last few years. The instruction serves as an educational resource and defines the process for transitioning facilities to long-term surveillance and maintenance (S and M). Generally, these facilities do not have identified operations missions and must be transitioned from operational status to a safe and stable configuration for long-term S and M. The instruction can be applied to a wide range of facilities--from process canyon complexes like the Plutonium Uranium Extraction Facility or B Plant, to stand-alone, lower hazard facilities like the 242B/BL facility. The facility transition process is implemented (under the direction of the US Department of Energy, Richland Operations Office [RL] Assistant Manager-Environmental) by Bechtel Hanford, Inc. management, with input and interaction with the appropriate RL division and Hanford site contractors as noted in the instruction. The application of the steps identified herein and the early participation of all organizations involved are expected to provide a cost-effective, safe, and smooth transition from operational status to deactivation and S and M for a wide range of Hanford Site facilities

  16. Computer assisted instruction on "learning nutrition flags for deaf 5th grade and 6th grad students": effectiveness of instruction. (United States)

    Srisorachatr, Suwat; Huadong, Yotsinee; Hudthagosol, Chatrapa; Danthanavanich, Suksiri


    Deaf students are of a number of under privilege group for whom there are limited resources for their use, related to health including nutrition. The purpose of this research was to create computer-assisted instruction for "nutrition flags" for 5 and 6th grade students. The content of nutrition included the concept of a healthy balance diets and portion sizes of each food group. The content and pictures for computer-assisted instruction came from existing curriculum, and focused on nutritional content. The contents in this instruction were divided into three units according to students' learning capacity. The story boards were developed by staff including nutritionists, Thai sign language interpreters, and deaf students. Then, the contents and nutrition vocabulary were translated into Thai sign language. After recording the sign language on video, this material was merged with the contents and converted into a computer program. The computer assisted instruction was tested with students from Nakon Pathom School for the Deaf The first trial was conducted with three students, the second with five students, and the third with 15 students during the academic year 2009. The computer- assisted instruction was revised until it met the standard criteria of 80/80. Effectiveness testing was carried out with 36 students for five consecutive days. On the first day, the pre-test was completed, and on days 2-4, the students performed self-study and completed the exercises for units 1-3, with 50 minutes spent on each unit. The post-test was completed on the last day. The study was conducted during the 2010 academic year Data analysis was performed using the t-test. The results showed an effectiveness of 81.85/82.22, which was higher than the standard criteria of 80/80. The post-test average score was higher than the pre-test average score with a statistical significance level at p < 0.0001. Suggestions for instruction for the deaf are that the length of the instruction in each

    Granzow, Martin; Hegenbart, Ute; Hinderhofer, Katrin; Hose, Dirk; Seckinger, Anja; Bochtler, Tilmann; Hemminki, Kari; Goldschmidt, Hartmut; Schönland, Stefan O; Jauch, Anna


    Immunoglobulin light chain (AL) amyloidosis is a rare plasma cell dyscrasia characterized by the deposition of abnormal amyloid fibrils in multiple organs, thus impairing their function. In the largest cohort studied up to now of 118 CD138-purified plasma cell samples from previously untreated immunoglobulin light chain amyloidosis patients, we assessed in parallel copy number alterations using high-density copy number arrays and interphase fluorescence in situ hybridization (iFISH). We used fluorescence in situ hybridization probes for the IgH translocations t(11;14), t(4;14), and t(14;16) or any other IgH rearrangement as well as numerical aberrations of the chromosome loci 1q21, 8p21, 5p15/5q35, 11q22.3 or 11q23, 13q14, 15q22, 17p13, and 19q13. Recurrent gains included chromosomes 1q (36%), 9 (24%), 11q (24%), as well as 19 (15%). Recurrent losses affected chromosome 13 (29% monosomy) and partial losses of 14q (19%), 16q (14%) and 13q (12%), respectively. In 88% of patients with translocation t(11;14), the hallmark chromosomal aberration in AL amyloidosis, a concomitant gain of 11q22.3/11q23 detected by iFISH was part of the unbalanced translocation der(14)t(11;14)(q13;q32) with the breakpoint in the CCND1/MYEOV gene region. Partial loss of chromosome regions 14q and 16q were significantly associated to gain 1q. Gain 1q21 detected by iFISH almost always resulted from a gain of the long arm of chromosome 1 and not from trisomy 1, whereas deletions on chromosome 1p were rarely found. Overall and event-free survival analysis found a potential adverse prognostic effect of concomitant gain 1q and deletion 14q as well as of deletion 1p. In conclusion, in the first whole genome report of clonal plasma cells in AL amyloidosis, novel aberrations and hitherto unknown potential adverse prognostic effects were uncovered.

    Objectives First, to evaluate the effect of standard vs pictograph-enhanced discharge instructions on patients’ immediate and delayed recall of and satisfaction with their discharge instructions. Second, to evaluate the effect of automated pictograph enhancement on patient satisfaction with their discharge instructions. Materials and Methods Glyph, an automated healthcare informatics system, was used to automatically enhance patient discharge instructions with pictographs. Glyph was developed at the University of Utah by our research team. Patients in a cardiovascular medical unit were randomized to receive pictograph-enhanced or standard discharge instructions. Measures of immediate and delayed recall and satisfaction with discharge instructions were compared between two randomized groups: pictograph (n = 71) and standard (n = 73). Results Study participants who received pictograph-enhanced discharge instructions recalled 35% more of their instructions at discharge than those who received standard discharge instructions. The ratio of instructions at discharge was: standard = 0.04 ± 0.03 and pictograph-enhanced = 0.06 ± 0.03. The ratio of instructions at 1 week post discharge was: standard = 0.04 ± 0.02 and pictograph-enhanced 0.04 ± 0.02. Additionally, study participants who received pictograph-enhanced discharge instructions were more satisfied with the understandability of their instructions at 1 week post-discharge than those who received standard discharge instructions. Discussion Pictograph-enhanced discharge instructions have the potential to increase patient understanding of and satisfaction with discharge instructions. Conclusion It is feasible to automatically illustrate discharge instructions and provide them to patients in a timely manner without interfering with clinical work. Illustrations in discharge instructions were found to improve patients’ short-term recall of discharge instructions and delayed satisfaction (1-week post hospitalization

    Nonyelum, Stanley Catherine; Nkem, Nwachukwu; Ifeyinwa, Chijoke-Nwauche; Orisakwe, Orish Ebere


    To investigate the adequacy of safety warnings and first aid instructions on the labels of pharmaceutical and consumer products in Nigeria. A market basket method (total collection of all available samples) was used to investigate the adequacy of safety warnings and first aid instructions on the labels of 600 pharmaceutical and consumer products in Nigeria. The results showed that 69.8% of the products had adequate warnings whereas 385 (64.1%) of the products screened had legible product warnings. Only 52 (8.7%) of the total number of products had appropriate first aid instructions while only 25 (4.12%) of the products described symptoms and full treatment of poisoning by the product and 319 (53.2%) products surveyed recommended calling a health professional. A total of 31 (5.2%) products had labels that were considered too technical (non English). Of the 600 products, 386 (64.3%) had dosage instructions that were considered adequate while 538 (89.6%) had adequate storage instructions. About 68% of the products had partially correct warnings while 44 or 7.3% had partially correct first aid instructions. Some products had neither warnings nor first aid instructions. This study suggests a not too impressive improvement in the correctness and appropriateness of label information.

  3. Comprehensive, Mixed-Methods Assessment of a Blended Learning Model for Geospatial Literacy Instruction (United States)

    Brodeur, J. J.; Maclachlan, J. C.; Bagg, J.; Chiappetta-Swanson, C.; Vine, M. M.; Vajoczki, S.


    Geospatial literacy -- the ability to conceptualize, capture, analyze and communicate spatial phenomena -- represents an important competency for 21st Century learners in a period of 'Geospatial Revolution'. Though relevant to in-course learning, these skills are often taught externally, placing time and resource pressures on the service providers - commonly libraries - that are relied upon to provide instruction. The emergence of online and blended modes of instruction has presented a potential means of increasing the cost-effectiveness of such activities, by simultaneously reducing instructional costs, expanding the audience for these resources, and addressing student preferences for asynchronous learning and '24-7' access. During 2011 and 2012, McMaster University Library coordinated the development, implementation and assessment of blended learning modules for geospatial literacy instruction in first-year undergraduate Social Science courses. In this paper, we present the results of a comprehensive mixed-methods approach to assess the efficacy of implementing blended learning modules to replace traditional (face-to-face), library-led, first-year undergraduate geospatial literacy instruction. Focus groups, personal interviews and an online survey were used to assess modules across dimensions of: student use, satisfaction and accessibility requirements (via Universal Instructional Design [UID] principles); instructor and teaching staff perception of pedagogical efficacy and instructional effectiveness; and, administrator cost-benefit assessment of development and implementation. Results showed that both instructors and students identified significant value in using the online modules in a blended-learning setting. Reaffirming assumptions of students' '24/7' learning preferences, over 80% of students reported using the modules on a repeat basis. Students were more likely to use the modules to better understand course content than simply to increase their grade in

  11. Laparoscopy Instructional Videos: The Effect of Preoperative Compared With Intraoperative Use on Learning Curves. (United States)

    Broekema, Theo H; Talsma, Aaldert K; Wevers, Kevin P; Pierie, Jean-Pierre E N

    Previous studies have shown that the use of intraoperative instructional videos has a positive effect on learning laparoscopic procedures. This study investigated the effect of the timing of the instructional videos on learning curves in laparoscopic skills training. After completing a basic skills course on a virtual reality simulator, medical students and residents with less than 1 hour experience using laparoscopic instruments were randomized into 2 groups. Using an instructional video either preoperatively or intraoperatively, both groups then performed 4 repetitions of a standardized task on the TrEndo augmented reality. With the TrEndo, 9 motion analysis parameters (MAPs) were recorded for each session (4 MAPs for each hand and time). These were the primary outcome measurements for performance. The time spent watching the instructional video was also recorded. Improvement in performance was studied within and between groups. Medical Center Leeuwarden, a secondary care hospital located in Leeuwarden, The Netherlands. Right-hand dominant medical student and residents with more than 1 hour experience operating any kind of laparoscopic instruments were participated. A total of 23 persons entered the study, of which 21 completed the study course. In both groups, at least 5 of 9 MAPs showed significant improvements between repetition 1 and 4. When both groups were compared after completion of repetition 4, no significant differences in improvement were detected. The intraoperative group showed significant improvement in 3 MAPs of the left-nondominant-hand, compared with one MAP for the preoperative group. No significant differences in learning curves could be detected between the subjects who used intraoperative instructional videos and those who used preoperative instructional videos. Intraoperative video instruction may result in improved dexterity of the nondominant hand. Copyright © 2016 Association of Program Directors in Surgery. Published by Elsevier Inc

  14. Engaging Pre-Service Teachers to Teach Science Contextually with Scientific Approach Instructional Video (United States)

    Susantini, E.; Kurniasari, I.; Fauziah, A. N. M.; Prastowo, T.; Kholiq, A.; Rosdiana, L.


    Contextual teaching and learning/CTL presents new concepts in real-life experiences and situations where students can find out the meaningful relationship between abstract ideas and practical applications. Implementing contextual teaching by using scientific approach will foster teachers to find the constructive ways of delivering and organizing science content. This research developed an instructional video that represented a modeling of using a scientific approach in CTL. The aim of this research are to engage pre-service teachers in learning how to teach CTL and to show how pre-service teachers’ responses about learning how to teach CTL using an instructional video. The subjects of this research were ten pre-service teachers in Department of Natural Sciences, Universitas Negeri Surabaya, Indonesia. All subjects observed the instructional video which demonstrated contextual teaching and learning combined with the scientific approach as they completed a worksheet to analyze the video content. The results showed that pre-service teachers could learn to teach contextually as well as applying the scientific approach in science classroom through a modeling in the instructional video. They also responded that the instructional video could help them to learn to teach each component contextual teaching as well as scientific approach.

  15. Using Technology and Assessment to Personalize Instruction: Preventing Reading Problems. (United States)

    Connor, Carol McDonald


    Children who fail to learn to read proficiently are at serious risk of referral to special education, grade retention, dropping out of high school, and entering the juvenile justice system. Accumulating research suggests that instruction regimes that rely on assessment to inform instruction are effective in improving the implementation of personalized instruction and, in turn, student learning. However, teachers find it difficult to interpret assessment results in a way that optimizes learning opportunities for all of the students in their classrooms. This article focuses on the use of language, decoding, and comprehension assessments to develop personalized plans of literacy instruction for students from kindergarten through third grade, and A2i technology designed to support teachers' use of assessment to guide instruction. Results of seven randomized controlled trials demonstrate that personalized literacy instruction is more effective than traditional instruction, and that sustained implementation of personalized literacy instruction first through third grade may prevent the development of serious reading problems. We found effect sizes from .2 to .4 per school year, which translates into about a 2-month advantage. These effects accumulated from first through third grade with a large effect size (d = .7) equivalent to a full grade-equivalent advantage on standardize tests of literacy. These results demonstrate the efficacy of technology-supported personalized data-driven literacy instruction to prevent serious reading difficulties. Implications for translational prevention research in education and healthcare are discussed.

    Gwen Nugent


    Full Text Available Learning objects originally developed for use in online learning environments can also be used to enhance face-to-face instruction. This study examined the learning impacts of online learning objects packaged into modules and used in different contexts for undergraduate education offered on campus at three institutions. A multi-case study approach was used, examining learning impacts across a variety of course subjects, course levels (introductory and advanced undergraduate, student levels (undergraduate and graduate, and instructional goals (i.e., replacement for lecture, remediation. A repeated measures design was used, with learning data collected prior to viewing the online module, after completion of the module, and at the end of the semester. The study provided a broad examination of ways that online modules are typically used in a college classroom, as well as measured learning effectiveness based on different instructional purpose and usage contexts. Results showed the effectiveness of the modules in serving as a substitute for classroom lecture, remediation of course prerequisite material, introduction to content with follow-up lab practice, and review for final exams. In each of these cases, the use of the modules resulted in significant learning increases, as well as retention of the learning until the end of the semester.

  17. Instructional immediacy in elearning. (United States)

    Walkem, Kerrie


    Instructor immediacy has been positively associated with many desirable academic outcomes including increased student learning. This study extends existing understanding of instructional immediacy behaviours in elearning by describing postgraduate nursing students' reflections on their own experience. An exploratory, descriptive survey design was used to collect qualitative data. Participants were asked what behaviours or activities help to create rapport or a positive interpersonal connection (immediacy) between students and their online teacher(s). Thematic analysis of the data revealed three main themes: acknowledging and affirming student's personal and professional responsibilities; providing clear and timely information; and utilising rich media. These findings give lecturers insight into instructional strategies they may adopt to increase immediacy in elearning and hence improve student learning outcomes.

  18. Getting to the point: attempting to improve juror comprehension of capital penalty phase instructions. (United States)

    Smith, Amy E; Haney, Craig


    This research examined the effects of several versions of capital penalty phase instructions on juror comprehension. Study One documented the impact of California's recently implemented "plain language" instruction. It showed that although the new instruction has clear advantages over the previous version, significant comprehension problems remain. Study Two evaluated several modified instructions designed to enhance comprehension. Participants heard either a standard patterned instruction or one of two alternatives-a psycholinguistically improved instruction, or a "pinpoint" instruction using case-related facts to illustrate key terms-in a simulated death penalty sentencing phase. Persons who heard modified instructions demonstrated higher levels of comprehension on virtually every measure as compared to those in the standard instruction condition.

    Siew Ean Lye


    Full Text Available This small-scale quasi-experimental study compared the effects of metacognitive strategy instruction using two pedagogical approaches on the metacognitive awareness of Malaysian ESL listeners. Embedded and direct strategy instruction was delivered using the Metacognitive Pedagogical Sequence and Cognitive Academic Language Learning Approach instructional models respectively. 45 tertiary level students were randomly selected and assigned to two treatment groups to receive metacognitive instruction over a training period of five weeks. Paired-samples t-test results on participants‟ metacognitive awareness, as measured using the Metacognitive Awareness Listening Questionnaire (MALQ were inclusive despite significant improvements in their IELTS listening scores. No significant development was recorded in the overall MALQ scores but there were significant changes in three out of the five metacognitive awareness factors. Results further layered according to participants‟ listening proficiency levels (low, intermediate and high to examine if differences existed among the listening levels similarly showed no significant difference. These results suggest that ESL listeners‟ metacognitive awareness may not be easily developed with strategy instruction, regardless of the instructional approaches.

  3. Development of a fresh cadaver model for instruction of ultrasound-guided breast biopsy during the surgery clerkship: pre-test and post-test results among third-year medical students. (United States)

    McCrary, Hilary C; Krate, Jonida; Savilo, Christine E; Tran, Melissa H; Ho, Hang T; Adamas-Rappaport, William J; Viscusi, Rebecca K


    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.

  5. The Effects of Blended Instruction on Oral Reading Performance and their Relationships to a Five-Factor Model of Personality

    Directory of Open Access Journals (Sweden)

    Isao Miyaji


    Full Text Available In recent times, 'Blended Instruction' - an effective method of instructions utilizing e-Learning materials in English education - consists of an individual learning part, a collaborative learning part and a teacher instruction part. In the individual learning, students act out model dialogues in the WBT courseware which incorporated a high quantity of video and sound clips. In the collaborative learning, students perform the dialogues in pairs and assessed each other's performance. Our recent research in a high school showed that the skill of the students' oral reading was improved in most criteria of assessment through blended instruction. However, it is still not clear what kind of relationship exists between the development of the students' oral reading skills and their personalities. With this in mind, the authors have studied the effects of the blended instruction on the junior high school students' oral reading performance and their relationships to the five-factor model of personality. The result of the research shows that the skill of the students' oral reading was improved in most criteria of assessment and the blended instruction was effective for the personality group, 'Introverted unintelligent person' in the most categories of oral reading criteria as well as the personality group, 'Sociable hard-worker'. The important factor for that group in oral reading performance turned out to be 'Sense Reading'.

  6. The effect of high school chemistry instruction on students' academic self-concept (United States)

    Morgan, Peter Wallace

    The purpose of this study was to investigate the effect of extended instruction in high school chemistry on the academic self-concept of students and determine what parts of the learning experience need to be addressed to make the interaction a more positive one. Fifty-seven students from three metropolitan public schools, who were enrolled in college preparatory chemistry classes, were asked to complete a written instrument, before and after extended chemistry instruction, that measures academic self-concept. Twenty-one of the students who took part in the written task volunteered to answer some in-depth interview questions concerning their academic self-concept and its relationship to chemistry instruction. Student responses, instrument scores, and student chemistry grades were analyzed for a variety of chemistry learning--academic self-concept connections and interactions. Results showed that there was a positive interaction for less than half of the students involved in the interview sessions. The results from the written instrument showed similar findings. Comparing chemistry grades and academic self-concept revealed an uncertain connection between the two, especially for students with strong academic self-concepts. Students felt that the laboratory experience was often disconnected from the remainder of chemistry instruction and recommended that the laboratory experience be integrated with classroom work. Students also expressed concerns regarding the volume of algorithmic mathematical calculations associated with college preparatory chemistry instruction. Results of this study suggest that secondary chemistry instruction must become more aware of the affective domain of learning and develop a mindful awareness of its connection to the cognitive domain if chemistry teaching and learning is going to better facilitate the intellectual growth of secondary students.

  7. Ninth Grade Student Responses to Authentic Science Instruction (United States)

    Ellison, Michael Steven

    science classwork was also measured. In addition, direct observation measures of student behavioral engagement showed that behavioral engagement was generally high, but not associated with the authenticity of the pedagogy. Direct observation measures of student self-regulation found evidence that when instruction focused on core science and engineering concepts and made stronger connections to the student's world beyond the classroom, student self-regulated learning was greater, and included evidence of student ownership. In light of the alignment between the model of authenticity used in this study and the Next Generation Science Standards (NGSS), the results suggest that further research on the value beyond school component of the model could improve understanding of student engagement and performance in response to the implementation of the NGSS. In particular, it suggests a unique role environmental education can play in affording student success in K-12 science and a tool to measure that role.

  8. Examining elementary teachers' knowledge and instruction of scientific explanations for fostering children's explanations in science (United States)

    Wiebke, Heidi Lynn

    This study employed an embedded mixed methods multi-case study design (Creswell, 2014) with six early childhood (grades K-2) teachers to examine a) what changes occurred to their subject matter knowledge (SMK) and pedagogical content knowledge (PCK) for teaching scientific explanations while participating in a professional development program, b) how they planned for and implemented scientific explanation instruction within a teacher developed unit on properties of matter, and c) what affordances their instruction of scientific explanations had on fostering their students' abilities to generate explanations in science. Several quantitative and qualitative measures were collected and analyzed in accordance to this studies conceptual framework, which consisted of ten instructional practices teachers should consider assimilating or accommodating into their knowledge base (i.e., SMK & PCK) for teaching scientific explanations. Results of this study indicate there was little to no positive change in the teachers' substantive and syntactic SMK. However, all six teachers did make significant changes to all five components of their PCK for teaching explanations in science. While planning for scientific explanation instruction, all six teachers' contributed some ideas for how to incorporate seven of the ten instructional practices for scientific explanations within the properties of matter unit they co-developed. When enacting the unit, the six teachers' employed seven to nine of the instructional practices to varying levels of effectiveness, as measured by researcher developed rubrics. Given the six teachers' scientific explanation instruction, many students did show improvement in their ability to formulate a scientific explanation, particularly their ability to provide multiple pieces of evidence. Implications for professional developers, teacher educators, researchers, policy makers, and elementary teachers regarding how to prepare teachers for and support students

  9. D4 S4: A Four Dimensions Instructional Strategy for Web-based and Blended Learning

    Directory of Open Access Journals (Sweden)

    Hamdy A. ABDELAZIZ,


    Full Text Available Web-based education is facing a paradigm shift under the rapid development of information and communication technology. The new paradigm of learning requires special techniques of course design, special instructional models, and special methods of evaluation. This paper investigates the effectiveness of an adaptive instructional strategy for teaching and learning through the Web and blended learning environments. The central theme of this strategy is that instructional strategies give instructors and students a conceptual as well as a practical mode of delivery from which to teach and learn. Considering and applying new instructional strategy can help instructors to understand the uses of pedagogical content knowledge, as well as to reflect the role of technological content knowledge that can be adapted and/or adopted in teaching in all educational levels and environments. The main objective of this paper was to develop a holonomic instructional strategy for Web-based and blended learning. This strategy is guided by the non-linear and interactive features of learning environments. The strategy is consisted of four dimensions: designing, developing, delving and distributing. In this new instructional strategy, learning is holonomic and adaptive. Learning occurs in an open learning environment, in which instructors are designing a shared vision, developing a sharable e-learning task, delving students’ learning through scaffolding and salvaging students’ knowledge. The expected outcome of this instructional strategy is that each learner will develop a cognitive schema to be used to organize and construct knowledge and meaning in similar context of learning which may increase the generalizability, trustworthiness and transferability of learning. The results of applying this new strategy showed that this strategy is effective on developing both achievement and deep learning levels among a sample of graduate students.

  14. Emergent literacy activities, instructional adaptations and school absence of children with cerebral palsy in special education. (United States)

    Peeters, Marieke; de Moor, Jan; Verhoeven, Ludo


    The goal of the present study was to get an overview of the emergent literacy activities, instructional adaptations and school absence of children with cerebral palsy (CP) compared to normally developing peers. The results showed that there were differences between the groups regarding the amount of emergent literacy instruction. While time dedicated to storybook reading and independent picture-book reading was comparable, the children with CP received fewer opportunities to work with educational software and more time was dedicated to rhyming games and singing. For the children with CP, the level of speech, intellectual, and physical impairments were all related to the amount of time in emergent literacy instruction.

    Directory of Open Access Journals (Sweden)

    María Andrea Beltrán-Herrera


    based on Lloyd (2007 six types of sections. The participants were 13 students aged 10 to 12 years old from fifth grade; a mixed method was carried out to analyze collected data through the following instruments: 2 tests (pre-post, recordings and artifacts. This analysis was made using randomly 6 chosen students. At first the students did the pre-test with 20 words containing the sounds / i: /, / I /, / / θ / and / ð /. In the second phase, the researchers implemented the stages of Phonics Instruction focusing on making visual, auditory, Kinesthetic and tactile. In the third stage, students did the post-test with 40 words containing / i: /, / I /, / θ / and / ð / sounds, the recordings obtained the pronunciation of students and transcripts of tests; so it could be determined if students improved their pronunciation of sounds with the use of Phonics Instruction. There were also artifacts as evidence of activities did by students. Finally, the results showed that the students had a breakthrough and Phonics Instruction contributed in their pronunciation achieving to identify differences and similarities in word pronunciation based on the minimal pairs.

    Full Text Available This study applied multimedia in a general engineering and technology course in Taiwan and evaluated the effectiveness of multimedia-assisted instruction and learning. The course presented trends in technological development and the achievements of Taiwanese industries and research institutes from a historical perspective, and overviewed the technology industries and industrial transformation development in Taiwan. The course units adopted multimedia to support class teaching and student learning, and a survey was conducted to collect students’ attitudes and perception toward multimedia-assisted instruction and learning in the course. Research data were collected from 45 male and 9 female students with varied academic and cultural backgrounds. Results showed that multimedia videos help raise students’ awareness of learning issues, improve their understanding of content, and increase the depth of their learning. Almost all students liked the approach of using multimedia to assist teaching and learning, preferring this approach over traditional lecture-based instruction. They also would recommend this course to their peers. This study also found that the degree of students’ engagement caused variance in the students’ perception of multimedia helpfulness in assisting their learning. Finally, this study further proposes suggestions in both design and research on applications of multimedia-enhanced learning in engineering and technology education.

  17. The Effectiveness of Web-Based Instruction: An Initial Inquiry

    Directory of Open Access Journals (Sweden)

    Tatana M. Olson


    Full Text Available As the use of Web-based instruction increases in the educational and training domains, many people have recognized the importance of evaluating its effects on student outcomes such as learning, performance, and satisfaction. Often, these results are compared to those of conventional classroom instruction in order to determine which method is “better.” However, major differences in technology and presentation rather than instructional content can obscure the true relationship between Web-based instruction and these outcomes. Computer-based instruction (CBI, with more features similar to Web-based instruction, may be a more appropriate benchmark than conventional classroom instruction. Furthermore, there is little consensus as to what variables should be examined or what measures of learning are the most appropriate, making comparisons between studies difficult and inconclusive. In this article, we review the historical findings of CBI as an appropriate benchmark to Web-based instruction. In addition, we review 47 reports of evaluations of Web-based courses in higher education published between 1996 and 2002. A tabulation of the documented findings into eight characteristics is offered, along with our assessments of the experimental designs, effect sizes, and the degree to which the evaluations incorporated features unique to Web-based instruction.

  18. Effects of multimedia vocabulary instruction on adolescents with learning disabilities. (United States)

    Kennedy, Michael J; Deshler, Donald D; Lloyd, John Wills


    The purpose of this experimental study is to investigate the effects of using content acquisition podcasts (CAPs), an example of instructional technology, to provide vocabulary instruction to adolescents with and without learning disabilities (LD). A total of 279 urban high school students, including 30 with LD in an area related to reading, were randomly assigned to one of four experimental conditions with instruction occurring at individual computer terminals over a 3-week period. Each of the four conditions contained different configurations of multimedia-based instruction and evidence-based vocabulary instruction. Dependent measures of vocabulary knowledge indicated that students with LD who received vocabulary instruction using CAPs through an explicit instructional methodology and the keyword mnemonic strategy significantly outperformed other students with LD who were taught using the same content, but with multimedia instruction that did not adhere to a specific theoretical design framework. Results for general education students mirrored those for students with LD. Students also completed a satisfaction measure following instruction with multimedia and expressed overall agreement that CAPs are useful for learning vocabulary terms. © Hammill Institute on Disabilities 2013.

  19. Tutorial Instruction in Science Education

    Directory of Open Access Journals (Sweden)

    Rhea Miles


    Full Text Available The purpose of the study is to examine the tutorial practices of in-service teachers to address the underachievement in the science education of K-12 students. Method: In-service teachers in Virginia and North Carolina were given a survey questionnaire to examine how they tutored students who were in need of additional instruction. Results: When these teachers were asked, “How do you describe a typical one-on-one science tutorial session?” the majority of their responses were categorized as teacher-directed. Many of the teachers would provide a science tutorial session for a student after school for 16-30 minutes, one to three times a week. Respondents also indicated they would rely on technology, peer tutoring, scientific inquiry, or themselves for one-on-one science instruction. Over half of the in-service teachers that responded to the questionnaire stated that they would never rely on outside assistance, such as a family member or an after school program to provide tutorial services in science. Additionally, very few reported that they incorporated the ethnicity, culture, or the native language of ELL students into their science tutoring sessions.

  20. Shaping instructional communication competence of preservice teachers (United States)

    Tandyonomanu, D.; Mutiah; Setianingrum, V. M.


    This study aims to understand the process of shaping communication competence. Participants were pre-service teachers in the primary school education teacher who conducted teaching program internship program. Observations and interviews found that culture, experience, and education were the components that developed the communication competence within the instructional context. The former two components dominantly shape communication instructional competencies, whereas the latter contributes insignificantly. Education emphasizes on teacher’s pedagogy and professional competences. In the future, educational institutions for pre-service teachers could use this research results to Determine the process of developing communication competence.

  3. The effects of instructions on the sensitivity of negatively reinforced human behavior to extinction. (United States)

    Alessandri, Jérôme; Cançado, Carlos R X


    The effects of instructions on the sensitivity of negatively reinforced (escape) behavior to extinction were studied. Initially, responding produced timeouts from pressing a force cell on a variable-ratio (VR) schedule, which was then discontinued (extinction). Based on extinction data, participants were distributed into two groups. Participants in the Persistence Group (for which response rates were low in extinction) were instructed that the experimenter expected them to continue responding in extinction after a second exposure to the VR schedule. Participants in the Extinction group (for which response rates were high in extinction) were instructed that the experimenter expected them to stop responding in extinction. Relative to the condition in which instructions were absent, extinction-response rates increased and decreased, respectively, for participants in the Persistence and Extinction groups. These results replicate and extend to negatively reinforced responding previous findings that showed behavioral control by instructions formulated as explicit experimenter demands or expectations.

  4. Situation and person attributions under spontaneous and intentional instructions: an fMRI study (United States)

    Kestemont, Jenny; Vandekerckhove, Marie; Ma, Ning; Van Hoeck, Nicole


    This functional magnetic resonance imaging (fMRI) research explores how observers make causal beliefs about an event in terms of the person or situation. Thirty-four participants read various short descriptions of social events that implied either the person or the situation as the cause. Half of them were explicitly instructed to judge whether the event was caused by something about the person or the situation (intentional inferences), whereas the other half was instructed simply to read the material carefully (spontaneous inferences). The results showed common activation in areas related to mentalizing, across all types of causes or instructions (posterior superior temporal sulcus, temporo-parietal junction, precuneus). However, the medial prefrontal cortex was activated only under spontaneous instructions, but not under intentional instruction. This suggests a bias toward person attributions (e.g. fundamental attribution bias). Complementary to this, intentional situation attributions activated a stronger and more extended network compared to intentional person attributions, suggesting that situation attributions require more controlled, extended and broader processing of the information.

  5. Implementation of Socioscientific Issues Instruction to Fostering Students’ Decision Making Based Gender on Environmental Pollution (United States)

    Rizal, H. P.; Siahaan, P.; Yuliani, G.


    The purpose of this study was to investigate the implementation socioscientific issues (SSI) instruction to examine students’ decision making based gender. Selection of environmental problem based on the consideration this issue has potential to evaluate from various scientific disciplines and may initiate to make decision. The participant was students grade VII in South Sulawesi. Pre experiment method was utilized in study with one group pre-test and post-test design. The instrument used in this study comprised of open-ended question, observation sheets for group discussion, sheet for interview and observation sheet of implementation instruction in class. The result indicated that instruction has been implemented successfully. It was found that pre-test and post-test was fostered with N-gain for male and female in medium category. Based on independent t test was found there was no difference improvement of decision making between male and female students. The group showed there was no difference between male group and female group, but a significant difference was noted in mix group. Students and teacher give positive response to the implementation of instruction. It is concluded that science instruction based SSI can be implemented to foster male and female decision making by forming group discussion.

  6. Evaluation of a pictograph enhancement system for patient instruction: a recall study. (United States)

    Zeng-Treitler, Qing; Perri, Seneca; Nakamura, Carlos; Kuang, Jinqiu; Hill, Brent; Bui, Duy Duc An; Stoddard, Gregory J; Bray, Bruce E


    We developed a novel computer application called Glyph that automatically converts text to sets of illustrations using natural language processing and computer graphics techniques to provide high quality pictographs for health communication. In this study, we evaluated the ability of the Glyph system to illustrate a set of actual patient instructions, and tested patient recall of the original and Glyph illustrated instructions. We used Glyph to illustrate 49 patient instructions representing 10 different discharge templates from the University of Utah Cardiology Service. 84 participants were recruited through convenience sampling. To test the recall of illustrated versus non-illustrated instructions, participants were asked to review and then recall a set questionnaires that contained five pictograph-enhanced and five non-pictograph-enhanced items. The mean score without pictographs was 0.47 (SD 0.23), or 47% recall. With pictographs, this mean score increased to 0.52 (SD 0.22), or 52% recall. In a multivariable mixed effects linear regression model, this 0.05 mean increase was statistically significant (95% CI 0.03 to 0.06, pillustration is a novel approach to improve the comprehension and recall of discharge instructions. Our results showed a statistically significant in recall with automated illustrations. Subjects with no-colleague education and younger subjects appeared to benefit more from the illustrations than others. Published by the BMJ Publishing Group Limited.

  7. Factors moderating blocking in human place learning: the role of task instructions. (United States)

    Hardt, Oliver; Hupbach, Almut; Nadel, Lynn


    Cognitive map theory assumes that novel environmental information is automatically incorporated into existing cognitive maps as a function of exploration. Reports of blocking in place learning cast doubt on this claim. In these studies, subjects were first trained to find a place, using a set of landmarks (Set A). Then novel landmarks (Set B) were added for additional trials. Subsequent removal of the Set A landmarks showed that the novel landmarks alone were insufficient for successful navigation. We investigated whether instructing human subjects to explore the environment can moderate blocking. First, we demonstrated that blocking is absent in a computer implementation of the Morris water maze (MWM) in which subjects are instructed to explore. We then studied why others found blocking in a different MWM implementation, in which the task instructions did not suggest exploration. In experiments that faithfully replicated this MWM variant, we found that subjects did not acquire cognitive maps and that blocking was attenuated when instructions were provided that encouraged exploration. Together, these findings indicate that blocking in human place learning may reflect a performance deficit, not a learning deficit, and that instructions can moderate blocking. Our results thus support the automatic update assumption of cognitive map theory.

    Kevin YEE

    Full Text Available Introduced in July, 2011 in a beta test of invited users only, the new social media service Google+ (or G+ quickly spread by word of mouth, and Google leader Larry Page (2011 blogged that within sixteen days it had 10 million users. By August, it had 25 million users (Cashmore, 2011. Even with slower growth ahead (still with no marketing budget, the service looks likely to crest 100 million users perhaps as early as ten months, a feat that took Facebook three years. Other social networks, most notably Facebook and Twitter, have been used increasingly as instructional tools, since they are platforms with which students are already familiar (Maloney, 2007; McLoughlin & Lee, 2007. Selwyn (2009 found that students often eschew official channels for communication in favor of less formal community-based formats such as Facebook, implying a growing need for instructional communication tools that will be used willingly by students. The question is whether Google+ can be used like Twitter or Facebook to augment instruction, or even, perhaps, to improve upon those predecessors for academic purposes. Google+ is like Twitter in that anyone can follow a given user’s posts. There is no direct “friend” relationship required to read the posts written by others. However, it also approximates some features of Facebook. Rather than friends sorted into “lists” like in Facebook, Google+ allows users to place feeds into one or more “circles,” the better to monitor (or control the flow of information to and from different audiences. Circles are more intuitive, and more central to the experience, than the Facebook lists. They provide an explicit organizational structure, compared to the less-obvious listing functionality, which feels like an afterthought, found in Facebook.

  12. Kinaesthetic activities in physics instruction

    DEFF Research Database (Denmark)

    Bruun, Jesper; Christiansen, Frederik V


    One of the major difficulties in learning physics is for students to develop a conceptual understanding of the core concepts of physics. Many authors argue that students’ conceptions of basic physical phenomena are rooted in basic schemas, originating in fundamental kinaesthetic experiences...... of being. We argue that this idea should be utilized in physics instruction, that kinaesthetic activities will provide useful entry point for students’ acquisition of the basic conceptions of physics, and that they can overcome the phenomenological gap between experiential and conceptual understanding. We...... discuss the nature of image schemas and focus particularly on one: effort-resistance-flow. This schema is fundamental not only in our everyday experience, but also in most of school physics. We show how enactment of a particular kinaesthetic model can support student understanding and intuition...

  18. Effects of explicit instruction on the acquisition of students' science inquiry skills in grades 5 and 6 of primary education (United States)

    Kruit, P. M.; Oostdam, R. J.; van den Berg, E.; Schuitema, J. A.


    In most primary science classes, students are taught science inquiry skills by way of learning by doing. Research shows that explicit instruction may be more effective. The aim of this study was to investigate the effects of explicit instruction on the acquisition of inquiry skills. Participants included 705 Dutch fifth and sixth graders. Students in an explicit instruction condition received an eight-week intervention of explicit instruction on inquiry skills. In the lessons of the implicit condition, all aspects of explicit instruction were absent. Students in the baseline condition followed their regular science curriculum. In a quasi-experimental pre-test-post-test design, two paper-and-pencil tests and three performance assessments were used to examine the acquisition and transfer of inquiry skills. Additionally, questionnaires were used to measure metacognitive skills. The results of a multilevel analysis controlling for pre-tests, general cognitive ability, age, gender and grade level indicated that explicit instruction facilitates the acquisition of science inquiry skills. Specifically on the performance assessment with an unfamiliar topic, students in the explicit condition outperformed students of both the implicit and baseline condition. Therefore, this study provides a strong argument for including an explicit teaching method for developing inquiry skills in primary science education.

  1. Effective Beginning Handwriting Instruction: Multi-modal, Consistent Format for 2 Years, and Linked to Spelling and Composing. (United States)

    Wolf, Beverly; Abbott, Robert D; Berninger, Virginia W


    In Study 1, the treatment group ( N = 33 first graders, M = 6 years 10 months, 16 girls) received Slingerland multi-modal (auditory, visual, tactile, motor through hand, and motor through mouth) manuscript (unjoined) handwriting instruction embedded in systematic spelling, reading, and composing lessons; and the control group ( N =16 first graders, M = 7 years 1 month, 7 girls) received manuscript handwriting instruction not systematically related to the other literacy activities. ANOVA showed both groups improved on automatic alphabet writing from memory; but ANCOVA with the automatic alphabet writing task as covariate showed that the treatment group improved significantly more than control group from the second to ninth month of first grade on dictated spelling and recognition of word-specific spellings among phonological foils. In Study 2 new groups received either a second year of manuscript ( N = 29, M = 7 years 8 months, 16 girls) or introduction to cursive (joined) instruction in second grade ( N = 24, M = 8 years 0 months, 11 girls) embedded in the Slingerland literacy program. ANCOVA with automatic alphabet writing as covariate showed that those who received a second year of manuscript handwriting instruction improved more on sustained handwriting over 30, 60, and 90 seconds than those who had had only one year of manuscript instruction; both groups improved in spelling and composing from the second to ninth month of second grade. Results are discussed in reference to mastering one handwriting format before introducing another format at a higher grade level and always embedding handwriting instruction in writing and reading instruction aimed at all levels of language.

    Receiving informative, well-structured, and well-designed instructions supports performance and memory in assembly tasks. We describe IBES, a tool with which users can quickly and easily create multimedia, step-by-step instructions by segmenting a video of a task into segments. In a validation study we demonstrate that the step-by-step structure of the visual instructions created by the tool corresponds to the natural event boundaries, which are assessed by event segmentation and are known to play an important role in memory processes. In one part of the study, 20 participants created instructions based on videos of two different scenarios by using the proposed tool. In the other part of the study, 10 and 12 participants respectively segmented videos of the same scenarios yielding event boundaries for coarse and fine events. We found that the visual steps chosen by the participants for creating the instruction manual had corresponding events in the event segmentation. The number of instructional steps was a compromise between the number of fine and coarse events.

  4. The effects of divided attention on encoding processes under incidental and intentional learning instructions: underlying mechanisms? (United States)

    Naveh-Benjamin, Moshe; Guez, Jonathan; Hara, Yoko; Brubaker, Matthew S; Lowenschuss-Erlich, Iris


    Divided attention (DA) at encoding has been shown to significantly disrupt later memory for the studied information. However, what type of processing gets disrupted during DA remains unresolved. In this study, we assessed the degree to which strategic effortful processes are affected under DA by comparing the effects of DA at encoding under intentional and pure incidental learning instructions. In three experiments, participants studied list of words or word pairs under either full or divided attention. Results of three experiments, which used different methodologies, converged to show that the effects of DA at encoding reduce memory performance to the same degree under incidental and intentional learning. Secondary task performance indicated that encoding under intentional learning instructions was more effortful than under incidental learning instructions. In addition, the results indicated enhanced attention to the initial appearance of the words under both types of learning instructions. Results are interpreted to imply that other processes, rather than only strategic effortful ones, might be affected by DA at encoding.

The hybrid electric-powered vehicles or those equipped with fuel cells have been highlighted by the Japanese manufacturers which allow considerable budgets in the research of less polluting vehicles. The exposed models, although being all different according to the manufacturer, use always a hybrid system: fuel cell/battery. The manufacturers have stressed too on the intelligent systems for navigation and safety as well as on the design and comfort. (O.M.)

  6. A National Study Assessing the Teaching and Learning of Introductory Astronomy; Part I: The Effect of Interactive Instruction (United States)

    Prather, E. E.; Rudolph, A. L.; Brissenden, G.; Schlingman, W. M.


    We present the results of a national study on the teaching and learning of astronomy taught in general education, non-science major, introductory astronomy courses (Astro 101). Nearly 4000 students enrolled in 69 sections of Astro 101 taught at 31 institutions completed (pre- and post- instruction) the Light and Spectroscopy Concept Inventory (LSCI) from Fall 2006 to Fall 2007. The classes varied in size from very small (N 4-year colleges and universities. To study how the instruction in different classrooms affected student learning, we developed and administered an Interactivity Assessment Instrument (IAI). This short survey, completed by instructors, allowed us to estimate the fraction of classroom time spent on learner- centered, active-engagement instruction such as Peer Instruction and collaborative tutorials. Pre-instruction LSCI scores were clustered around ˜25% (24 ± 2%), independent of class size and institution type; however, the gains measured varied from about (-)0.07-0.50. The distribution of gain scores indicates that differences were due to instruction in the classroom, not the type of class or institution. Interactivity Assessment Scores (IAS's) ranged from 0%-50%, showing that our IAI was able to distinguish between classes with higher and lower levels of interactivity. A comparison of class-averaged gain score to IAS showed that higher interactivity classes (IAS > 25%) were the only instructional environments capable of reaching the highest gains ( > 0.30). However, the range of gains seen for both groups of classes was quite wide, suggesting that the use of interactive learning strategies is not sufficient by itself to achieve high student gain.

  7. Reality show: um paradoxo nietzschiano

    Directory of Open Access Journals (Sweden)

    Ilana Feldman


    Full Text Available

    O fenômeno dos reality shows - e a subseqüente relação entre imagem e verdade - assenta-se sobre uma série de paradoxos. Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

  8. The equivalence of learning paths in early science instruction: effect of direct instruction and discovery learning. (United States)

    Klahr, David; Nigam, Milena


    In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.

  10. Using embedded computer-assisted instruction to teach science to students with Autism Spectrum Disorders (United States)

    Smith, Bethany

    The need for promoting scientific literacy for all students has been the focus of recent education reform resulting in the rise of the Science Technology, Engineering, and Mathematics movement. For students with Autism Spectrum Disorders and intellectual disability, this need for scientific literacy is further complicated by the need for individualized instruction that is often required to teach new skills, especially when those skills are academic in nature. In order to address this need for specialized instruction, as well as scientific literacy, this study investigated the effects of embedded computer-assisted instruction to teach science terms and application of those terms to three middle school students with autism and intellectual disability. This study was implemented within an inclusive science classroom setting. A multiple probe across participants research design was used to examine the effectiveness of the intervention. Results of this study showed a functional relationship between the number of correct responses made during probe sessions and introduction of the intervention. Additionally, all three participants maintained the acquired science terms and applications over time and generalized these skills across materials and settings. The findings of this study suggest several implications for practice within inclusive settings and provide suggestions for future research investigating the effectiveness of computer-assisted instruction to teach academic skills to students with Autism Spectrum Disorders and intellectual disability.

  11. Safe from harm: learned, instructed, and symbolic generalization pathways of human threat-avoidance.

    Directory of Open Access Journals (Sweden)

    Simon Dymond

    Full Text Available Avoidance of threatening or unpleasant events is usually an adaptive behavioural strategy. Sometimes, however, avoidance can become chronic and lead to impaired daily functioning. Excessive threat-avoidance is a central diagnostic feature of anxiety disorders, yet little is known about whether avoidance acquired in the absence of a direct history of conditioning with a fearful event differs from directly learned avoidance. In the present study, we tested whether avoidance acquired indirectly via verbal instructions and symbolic generalization result in similar levels of avoidance behaviour and threat-beliefs to avoidance acquired after direct learning. Following fear conditioning in which one conditioned stimulus was paired with shock (CS+ and another was not (CS-, participants either learned or were instructed to make a response that cancelled impending shock. Three groups were then tested with a learned CS+ and CS- (learned group, instructed CS+ (instructed group, and generalized CS+ (derived group presentations. Results showed similar levels of avoidance behaviour and threat-belief ratings about the likelihood of shock across each of the three pathways despite the different mechanisms by which they were acquired. Findings have implications for understanding the aetiology of clinical avoidance in anxiety.

  13. Heuristic guidelines and experimental evaluation of effective augmented-reality based instructions for maintenance in nuclear power plants

    International Nuclear Information System (INIS)

    Yim, Ho Bin; Seong, Poong Hyun


    Research highlights: → Augmented reality (AR) instructions were built for NPPs maintenance personnel. → 4-5 pieces of information at a time were optimum for AR instructions in this study. → A large variance in mode no. 5 implies these were also found to be critical amount. → Heuristic guidelines were suggested to make AR instructions more effective. - Abstract: As industrial plants and factories age, their maintenance requirements increase. Because maintenance mistakes directly increase the operating costs of a power plant, maintenance quality is significant concern to plant management. By law, all personnel working with nuclear technology must be re-trained every three years in Korea; however, as the statistical data show, the number of shutdown accidents at nuclear power plants (NPPs) due to maintenance failure is still high and needs to be reduced. Industries have started to adopt various technologies to increase the speed and accuracy of maintenance. Among those technologies, augmented reality (AR) is the latest multimedia presentation technology to be applied to plant maintenance, and it offers superior intuitiveness and user interactivity over other conventional multimedia. This empirical study aims to measure the optimum amounts of information to be delivered at a time and to identify what types of information enhance the learning ability of novices and to suggest heuristic guidelines by which to make effective AR training instructions. In the first experiment, the optimum amount of information in an AR learning environment for novices was found to be 4-5 pieces of information in a chunk by comparing results between a pre-test and an after-test. This result implies that intentionally made chunks help novices learn more effectively. In the second experiment, the AR training instruction based on the suggested heuristic guidelines was slightly more effective than other AR training instructions. Maintenance in nuclear power plants can be more reliable

    Saga Pohjola-Ahlin


    Full Text Available In May 2016, 48 third semester undergraduate students enrolled in the physiotherapy program at Karolinska Institutet in Sweden were given three sets of questionnaires; before the information literacy instruction (ILI started, at the end of the first session, and a week after, at the end of the second and last session. The aim of this small-scale pilot study was to shed some light on students’ motivation to attend ILI, how they value the sessions afterwards and how they assess their learning outcome. Furthermore, it was an attempt to do a "students’ user experience study” in a pedagogical setting, with the intention to evaluate and improve teaching in ILI to meet student expectations. The average response rate for the three questionnaires was 92%. The results show that students’ expectations were similar to the actual content of ILI, and that the students were satisfied with their own learning outcome. Both motivation and the sense of relevance got higher scores after students attended ILI. Motivation rose from 7,4 to 8,12 out of 10. This is positive because a high level of motivation often improves the learning outcome (Schunk, 2012. When asked which areas most needed improvement in order to further enhance their learning outcome, the most common responses were “the pedagogy” and “my own achievement”. It would be interesting to start collaborating with a group of students in order to explore new methods and learning activities.

  17. The Impact of a Strategies-Based Instruction on Iranian EAP Students’ Reading Strategy Use: Developing Strategic EAP Readers

    Directory of Open Access Journals (Sweden)

    Seyyed Hossein Kashef


    Full Text Available Underperformance of students in EAP reading comprehension has been an issue of concern for teachers, syllabus designers, and curriculum developers in general and for EAP practitioners in particular. In spite of the fact that considerable efforts have been made to improve reading comprehension of students through strategies instruction over past decades, EAP students however have not benefited much from learning strategies. Thus, this study intended to investigate the impact of a Strategies-Based Instruction (SBI on undergraduate students’ reading strategy use in an EAP context. Taking an instructional model from strategies taxonomy of Oxford (1990; 2001, it was assumed that in contrast to conventional EAP reading methods, SBI would be more effective in encouraging reading strategy use and as a result developing reading comprehension of EAP students through encouraging the use of effective strategies and skills. To do so, 80 freshman undergraduate students were chosen as the participants of this study who were in two intact classes. After administration of a pre-test, treatment (22 sessions, 2 sessions per week, and a post-test, the collected data was analyzed using t-test to examine the effect of the proposed method of instruction. The results of the analysis showed that the teaching intervention had a significant effect on students’ reading strategy use. The findings have implications for teachers encouraging effective reading comprehension instruction through the use of strategies in EAP teaching contexts.

  18. Employing Augmented-Reality-Embedded Instruction to Disperse the Imparities of Individual Differences in Earth Science Learning (United States)

    Chen, Cheng-ping; Wang, Chang-Hwa


    Studies have proven that merging hands-on and online learning can result in an enhanced experience in learning science. In contrast to traditional online learning, multiple in-classroom activities may be involved in an augmented-reality (AR)-embedded e-learning process and thus could reduce the effects of individual differences. Using a three-stage AR-embedded instructional process, we conducted an experiment to investigate the influences of individual differences on learning earth science phenomena of "day, night, and seasons" for junior highs. The mixed-methods sequential explanatory design was employed. In the quantitative phase, factors of learning styles and ICT competences were examined alongside with the overall learning achievement. Independent t tests and ANCOVAs were employed to achieve inferential statistics. The results showed that overall learning achievement was significant for the AR-embedded instruction. Nevertheless, neither of the two learner factors exhibited significant effect on learning achievement. In the qualitative phase, we analyzed student interview records, and a wide variation on student's preferred instructional stages were revealed. These findings could provide an alternative rationale for developing ICT-supported instruction, as our three-stage AR-embedded comprehensive e-learning scheme could enhance instruction adaptiveness to disperse the imparities of individual differences between learners.

    Lutfi, A.; Hidayah, R.


    The aim of this study is to know the effect of Internet-assisted Chemmy Card 6-1 game as an instructional medium in IUPAC Nomenclature of Inorganic Compounds material for X grade of senior high school on students’ activity, learning motivation, and learning outcome. The study was conducted at SMA Negeri Sidoarjo, Indonesia, in two different classes. The instruction was done based on the lesson plan made. The observation on students’ activity was conducted during the instruction with the game while test and questionnaire were given after the instruction. The result showed positive activities, which students listened to the teacher’s explanation, actively delivered questions, and enabled to solve problems in naming compounds. It was also effective to avoid the drowsiness. The result of students’ motivation of X MIPA 6 was 74.78% (good) while X MIPA 7 was 83.80% (very good). The pretest results of two classes showed that no students mastered but 100% students mastered and the increase of N-gain scores in two classes was categorized as high, ≥0,7, after the instruction. The result of this study showed that the use of Internet-assisted Chemmy Card 6-1 game in IUPAC nomenclature of inorganic compounds for X grade of senior high school could be pleasant for students to learn and effective in achieving the learning objective.

  6. Generalization of socially transmitted and instructed avoidance

    Directory of Open Access Journals (Sweden)

    Gemma eCameron


    Full Text Available Excessive avoidance behavior, in which an instrumental action prevents an upcoming aversive event, is a defining feature of anxiety disorders. Left unchecked, both fear and avoidance of potentially threatening stimuli may generalize to perceptually related stimuli and situations. The behavioral consequences of generalization mean that aversive learning experiences with specific threats may lead people to infer that classes of related stimuli are threatening, potentially dangerous, and need to be avoided, despite differences in physical form. Little is known about avoidance generalization in humans and the learning pathways by which it may be transmitted. In the present study, we compared two pathways to avoidance, instructions and social observation, on subsequent generalization of avoidance behavior, fear expectancy and physiological arousal. Participants first learned that one cue was a danger cue (conditioned stimulus, CS+ and another was a safety cue (CS-. Groups then were either instructed that a simple avoidance response in the presence of the CS+ cancelled upcoming shock presentations (instructed-learning group or observed a short movie showing a demonstrator performing the avoidance response to prevent shock (observational-learning group. During generalization testing, danger and safety cues were presented along with generalization stimuli that parametrically varied in perceptual similarity to the CS+. Reinstatement of fear and avoidance was also tested. Findings demonstrate, for the first time, generalization of socially transmitted and instructed avoidance: both groups showed comparable generalization gradients in fear expectancy, avoidance behavior and arousal. Return of fear was evident, suggesting that generalized avoidance remains persistent following extinction testing. The utility of the present paradigm for research on avoidance generalization is discussed.

    Taffe, P


    There has been much discussion concerning the economics of using biomass for the production of substitute fuels and it has been argued that the net energy gain could be small or even negative. The development of the ATPAL process is described and it is claimed that only one quarter of the energy equivalent contained in the alcohol will be consumed in the total process. Both the pilot plant and a commercial scale plant with some modifications are described. The most significant advantage claimed for the ATPAL process is in its low process energy savings resulting from mechanical vapour recompression, recycling the heat and production of a low volume of effluent.

    Full Text Available Objectification refers to the way in which everything (including human beings is treated as an object, raw material, or resource to be manipulated and used. In this article, objectification refers to the way that education is often reduced to the packaging and delivery of information. A critique of objectification in instructional technology is presented. In the context of Heidegger’s critique of technology, the authors claim that objectification in education is metaphysical in the sense that the intelligibility (being of education is equated with ready-to-use packages, and thus is reduced to delivery and transmission of objects. The embodiment dimension of teaching and learning can help us in resisting this reduction. The authors argue that objectification increases bureaucratic control over the teaching process and deskills teachers; and by which teachers are proletarianized. The authors conclude that instructional designers should create structures in which a care relation and dialogue between students and teachers can take place. Résumé: L’objectification réfère à la façon dont tout (incluant les être humains est traité comme un objet, une matière première ou une ressource qui peut être manipulée et utilisée. Dans cet article, l’objectification réfère à la façon dont l’éducation est souvent réduite à la mise en boîte et à la livraison de l’information. Une critique de l’objectification en technologie éducative est présentée. Dans le contexte de la critique de la technologie par Heidegger, les auteurs prétendent que l’objectification en éducation est métaphysique dans le sens que l’intelligibilité (être de l’éducation équivaut à la mise en boîte prêt-à –utiliser, et se résume donc à la livraison et à la transmission d’objets.

  14. Internet-based instruction in college teaching (United States)

    Flickinger, Kathleen Anne

    Distance education and Internet instruction are increasingly being used in college science teaching. In an effort to reach more students, Iowa State University's Human Anatomy and Physiology course was offered via Internet as well as via traditional lecture format. To assess the educational ramifications of this offering, three studies were conducted. In the first study, a collective case study approach was utilized to describe the learning environment created by an Internet-based college science course. In this study, three students were followed as they worked their way through the course. Collective case study methodologies were used to provide a rich description of the learning environment experienced by these students. Motivation, computer savvy, and academic and personal self-confidence appeared to impact the satisfaction level of the students enrolled in the class. To evaluate the effectiveness of the learning environment offered through the Internet-based science course, a quantitative comparison study was undertaken. In this study a comparison of achievement scores and study habits between students enrolled in the Internet-based class and those enrolled in the traditional section was made. Results from this study indicated that content understanding and retention did not appear to be effected by the type of instruction. Desirable study habits were reportedly used more frequently in the Internet section of the class than in the traditional class. To complete the description of the Internet course experience, a qualitative examination of Internet instructors' time commitment and level of teaching satisfaction was conducted. Data for this study consisted of interviews and researcher observations. Instructor time-on-task was initially quite high, and remained above the average spent on average face-to-face instruction in subsequent semesters. Additionally the role of the faculty member changed dramatically, causing some lessening of job satisfaction. Taken as

    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.

  17. Elementary Students' Learning of Materials Science Practices Through Instruction Based on Engineering Design Tasks (United States)

    Wendell, Kristen Bethke; Lee, Hee-Sun


    Materials science, which entails the practices of selecting, testing, and characterizing materials, is an important discipline within the study of matter. This paper examines how third grade students' materials science performance changes over the course of instruction based on an engineering design challenge. We conducted a case study of nine students who participated in engineering design-based science instruction with the goal of constructing a stable, quiet, thermally comfortable model house. The learning outcome of materials science practices was assessed by clinical interviews conducted before and after the instruction, and the learning process was assessed by students' workbooks completed during the instruction. The interviews included two materials selection tasks for designing a sturdy stepstool and an insulated pet habitat. Results indicate that: (1) students significantly improved on both materials selection tasks, (2) their gains were significantly positively associated with the degree of completion of their workbooks, and (3) students who were highly engaged with the workbook's reflective record-keeping tasks showed the greatest improvement on the interviews. These findings suggest the important role workbooks can play in facilitating elementary students' learning of science through authentic activity such as engineering design.

  18. Profile of elementary school science teacher instruction in disaster risk reduction: case study of volcano disaster (United States)

    Pujianto; Prabowo; Wasis


    This study examined the profile of science' teacher instruction in Disaster Risk Reduction (DRR), as a feature of instructional quality, on students’ learning experiences. A qualitative study was done to observe teacher activities in teaching of disaster preparedness. Science teacher and 14 students at grade 4 of SDN (elementary school) Kiyaran 2 are involved as the subject of this study. Teacher’ instruction was coded with regard to preparation, action, and evaluation using observation sheets and documentation. Data analysis results showed a positive significant effect of the readiness during preparation on learning process of disaster risk reduction and an indirect effect of teacher’ action on students’ learning experiences. There is a lack of teaching materials about volcano disaster in the elementary school. Teacher found difficulties on evaluation of student achievement in disaster preparedness. These findings highlight the importance of DRR in uphold science teachers’ education. Items of teachers’ skill in preparing of DRR may be used to offer model of concrete instruction situation during university workshop for maintain teacher education.

  19. [A qualitative analysis of spelling mistakes and a systematic supportive learning instruction of spelling disorder]. (United States)

    Corvacho Del Toro, Irene M


    This paper explains how a qualitative analysis of spelling mistakes (Oldenburger Fehleranalyse, Thomé & Thomé, 2014) may be used to select learning materials according to individual needs. The pre-post design with control group serves to evaluate the effects of an intervention that is systematic and learning supportive for pupils with a diagnosed spelling disorder (ages 12 to 14; 6th-8th grade). Therapists of the experimental group were instructed to apply a series of linguistic and psycholinguistic criteria when creating the material for instruction and when carrying out the therapy. Therapists of the control group carried out the intervention without attending to these criteria, although they did have knowledge about the pupil’s profile in spelling mistakes. The intervention included 20 sessions. The ANOVA shows improvement for both groups (HSP, May 2012): (F(1, 14) = 15,05, p = .002, η2 = .518). For the experimental group it is stronger, and the difference in achievement gain is significant (F(1, 14) = 4,70, p = .048; η2 = .25). These results support a combination of qualitative analysis and a high qualification for therapists that relates specifically to orthography and its instruction. For some pupils the changes in the qualitative profiles reveal persistent support requirements in phonology or grammar instruction.

  20. Instruction, Feedback and Biometrics: The User Interface for Fingerprint Authentication Systems (United States)

    Riley, Chris; Johnson, Graham; McCracken, Heather; Al-Saffar, Ahmed

    Biometric authentication is the process of establishing an individual’s identity through measurable characteristics of their behaviour, anatomy or physiology. Biometric technologies, such as fingerprint systems, are increasingly being used in a diverse range of contexts from immigration control, to banking and personal computing. As is often the case with emerging technologies, the usability aspects of system design have received less attention than technical aspects. Fingerprint systems pose a number of challenges for users and past research has identified issues with correct finger placement, system feedback and instruction. This paper describes the development of an interface for fingerprint systems using an iterative, participative design approach. During this process, several different methods for the presentation of instruction and feedback were identified. The different types of instruction and feedback were tested in a study involving 82 participants. The results showed that feedback had a statistically significant effect on overall system performance, but instruction did not. The design recommendations emerging from this study, and the use of participatory design in this context, are discussed.

  1. The Effects of Inquiry-Based Integrated Information Literacy Instruction: Four-Year Trends

    Lin Ching Chen


    Full Text Available The purpose of this study was to examine the effects of four-year integrated information literacy instruction via a framework of inquiry-based learning on elementary students’ memory and comprehension. Moderating factors of students’ academic achievement was another focus of this study. The subjects were 72 students who have participated in this study since they entered an elementary school in Chiayi district. This elementary school adopted the integrated information literacy instruction, designed by the researchers and elementary school teachers, and integrated it into various subject matters via a framework of inquiry-based learning, such as Super 3 and Big6 models. A series of inquiry-based integrated information literacy instruction has been implemented since the second semester of the subjects’ first grade. A total of seven inquiry learning projects has been implemented from grade one through grade four. Fourteen instruments were used as pretests and posttests to assess students’ factual recall and conceptual understanding of subject contents in different projects. The results showed that inquiry-based integrated information literacy instruction couldhelp students memorize facts and comprehend concepts of subject contents. Regardless ofacademic achievements, if students would like to devote their efforts to inquiry processes, their memory and comprehension of subject contents improvedeffectively. However, students of low-academic achievement might need more time to be familiar with the inquiry-based learning strategy.

  2. Validity of "Hi_Science" as instructional media based-android refer to experiential learning model (United States)

    Qamariah, Jumadi, Senam, Wilujeng, Insih


    Hi_Science is instructional media based-android in learning science on material environmental pollution and global warming. This study is aimed: (a) to show the display of Hi_Science that will be applied in Junior High School, and (b) to describe the validity of Hi_Science. Hi_Science as instructional media created with colaboration of innovative learning model and development of technology at the current time. Learning media selected is based-android and collaborated with experiential learning model as an innovative learning model. Hi_Science had adapted student worksheet by Taufiq (2015). Student worksheet had very good category by two expert lecturers and two science teachers (Taufik, 2015). This student worksheet is refined and redeveloped in android as an instructional media which can be used by students for learning science not only in the classroom, but also at home. Therefore, student worksheet which has become instructional media based-android must be validated again. Hi_Science has been validated by two experts. The validation is based on assessment of meterials aspects and media aspects. The data collection was done by media assessment instrument. The result showed the assessment of material aspects has obtained the average value 4,72 with percentage of agreement 96,47%, that means Hi_Science on the material aspects is in excellent category or very valid category. The assessment of media aspects has obtained the average value 4,53 with percentage of agreement 98,70%, that means Hi_Science on the media aspects is in excellent category or very valid category. It was concluded that Hi_Science as instructional media can be applied in the junior high school.

  3. Embedding Affective Learning Outcomes in Library Instruction

    Ellysa Stern Cahoy


    Full Text Available While information literacy in higher education has long been focused on cognitive learning outcomes, attention must be paid to students’ affective, emotional needs throughout the research process. This article identifies models for embedding affective learning outcomes within information literacy instruction, and provides strategies to help librarians discover, articulate, and address students’ self-efficacy, motivation, emotions and attitudes. Worksheets to assist in creating affective learning outcomes are included to bring structure to an area of learning that is often challenging to articulate and measure. Also included in the article are the results of a recent survey of instruction librarians’ familiarity and inclusion of affective learning outcomes within teaching and learning initiatives.

  4. Inspiring Instructional Change in Elementary School Science: The Relationship Between Enhanced Self-efficacy and Teacher Practices (United States)

    Sandholtz, Judith Haymore; Ringstaff, Cathy


    This longitudinal study examined the extent to which teachers' participation in a 3-year professional development program enhanced their self-efficacy and prompted changes in science instruction in the early elementary grades. The study used a mixed-methods design, and included 39 teachers who taught in kindergarten, first grade, or second grade classrooms in rural school districts. Data sources, administered pre-program and at the end of each year, included a self-efficacy assessment and teacher survey. Interviews and classroom observations provided corroborating data about teachers' beliefs and science instruction. Results showed significant increases in teachers' overall self-efficacy in teaching science, personal efficacy, and outcome expectancy efficacy during the 3 years. Gains in self-efficacy were correlated with changes in reported instructional practices, particularly student participation activities. However, changes in self-efficacy tended not to be correlated with changes in instructional time. Contextual factors beyond teachers' direct control, such as curricular and testing requirements in mathematics and language arts influenced time allotted to science instruction.

  6. A multimedia adult literacy program: Combining NASA technology, instructional design theory, and authentic literacy concepts (United States)

    Willis, Jerry W.


    For a number of years, the Software Technology Branch of the Information Systems Directorate has been involved in the application of cutting edge hardware and software technologies to instructional tasks related to NASA projects. The branch has developed intelligent computer aided training shells, instructional applications of virtual reality and multimedia, and computer-based instructional packages that use fuzzy logic for both instructional and diagnostic decision making. One outcome of the work on space-related technology-supported instruction has been the creation of a significant pool of human talent in the branch with current expertise on the cutting edges of instructional technologies. When the human talent is combined with advanced technologies for graphics, sound, video, CD-ROM, and high speed computing, the result is a powerful research and development group that both contributes to the applied foundations of instructional technology and creates effective instructional packages that take advantage of a range of advanced technologies. Several branch projects are currently underway that combine NASA-developed expertise to significant instructional problems in public education. The branch, for example, has developed intelligent computer aided software to help high school students learn physics and staff are currently working on a project to produce educational software for young children with language deficits. This report deals with another project, the adult literacy tutor. Unfortunately, while there are a number of computer-based instructional packages available for adult literacy instruction, most of them are based on the same instructional models that failed these students when they were in school. The teacher-centered, discrete skill and drill-oriented, instructional strategies, even when they are supported by color computer graphics and animation, that form the foundation for most of the computer-based literacy packages currently on the market may not

  7. The effect of instruction on knowledge and attitude of couples attending pre-marriage counseling classes. (United States)

    Moodi, Mitra; Miri, Mohammad-Reza; Reza Sharifirad, Gholam


    Marriages and establishing a family is one of the most important events in the life of each person. It has significant effects on personal and social health, if it occurs with sufficient knowledge in the proper conditions. The aim of this study is to determine the effect of pre-marriage instruction on the knowledge and health attitudes of the couples attending the pre-marriage counseling classes. This pre and post quasi-experimental study was conducted on 250 couples attending the pre-marriage counseling classes. The required information was collected using an autonomous questionnaire designed based on the research objectives. The questionnaire included three parts: Demographic information, knowledge (27 questions) and attitude (18 questions. The questionnaire was filled out before and after the pre-marriage counseling program, which was presented as lectures. The effect of the instructional program was analyzed using a statistical test. The results showed that 83.2% of the couples had poor knowledge, 16% average, and 0.8% had good knowledge before the intervention. After the intervention, 60.4% of couples had poor knowledge, 31.6% average and 8% had good knowledge. The results also revealed that that the difference in mean scores of knowledge and attitudes regarding reproductive health, family planning, genetic diseases and disabilities was statistically significant (P < 0.001). Despite the mean scores of knowledge and attitude of the couples had increased after the instructional intervention, the increase in knowledge level was not very high. So the knowledge score of the couples increased just 4.3%, and only 8% of the couples had good knowledge after the instructional intervention. Therefore, to achieve a relatively stable behavior change in individuals and improving the health level of the young couples, it is recommended that more attention pay to the quality of the instructional classes.

  8. Effect of lecture instruction on student performance on qualitative questions (United States)

    Heron, Paula R. L.


    The impact of lecture instruction on student conceptual understanding in physics has been the subject of research for several decades. Most studies have reported disappointingly small improvements in student performance on conceptual questions despite direct instruction on the relevant topics. These results have spurred a number of attempts to improve learning in physics courses through new curricula and instructional techniques. This paper contributes to the research base through a retrospective analysis of 20 randomly selected qualitative questions on topics in kinematics, dynamics, electrostatics, waves, and physical optics that have been given in introductory calculus-based physics at the University of Washington over a period of 15 years. In some classes, questions were administered after relevant lecture instruction had been completed; in others, it had yet to begin. Simple statistical tests indicate that the average performance of the "after lecture" classes was significantly better than that of the "before lecture" classes for 11 questions, significantly worse for two questions, and indistinguishable for the remaining seven. However, the classes had not been randomly assigned to be tested before or after lecture instruction. Multiple linear regression was therefore conducted with variables (such as class size) that could plausibly lead to systematic differences in performance and thus obscure (or artificially enhance) the effect of lecture instruction. The regression models support the results of the simple tests for all but four questions. In those cases, the effect of lecture instruction was reduced to a nonsignificant level, or increased to a significant, negative level when other variables were considered. Thus the results provide robust evidence that instruction in lecture can increase student ability to give correct answers to conceptual questions but does not necessarily do so; in some cases it can even lead to a decrease.

    Training of rehearsal strategy and instruction about its value for serial recall were given to preschool children. For non-spontaneous rehearsers, the rehearsal training resulted in good recall performance. Instruction about its value helped maintain the effects of training. These results confirmed the results of Kennedy & Miller (1976) Spontaneously rehearsing preschoolers continued to perform well with or without such instruction. The possibility that even preschoolers, once they acquire sp...

  10. A Comprehensive Evaluation Rubric for Assessing Instructional Apps

    Directory of Open Access Journals (Sweden)

    Cheng-Yuan Lee


    Full Text Available There is a pressing need for an evaluation rubric that examines all aspects of educational apps designed for instructional purposes. In past decades, many rubrics have been developed for evaluating educational computer-based programs; however, rubrics designed for evaluating the instructional implications of educational apps are scarce. When an Internet search for existing rubrics was conducted, only two such rubrics were found, and the evaluation criteria used in those rubrics was not clearly linked to previously conducted research nor were their evaluative dimensions clearly defined. These shortcomings result in reviewers being unable to use those rubrics to provide teachers with a precise analysis of an educational app’s instructional potential. In response, this paper presents a comprehensive rubric with 24-evaluative dimensions tailored specifically to analyze the educational potential of instructional apps.

    Seyed Jalal Abdolmanafi (Rokni


    Full Text Available Problem Statement: Relativization is an important grammatical sub-system for second language learners. This study intended to explore the effects of different types of L2 instruction on the learning of English relative clauses by Persian learners.Purpose: The differential effects of the three types of treatment (i.e., Focus on FormS, Focus on Meaning, Focus on Form on the learning of English relativization was investigated.Methods: Intact university classes of English learners were divided into three groups receiving different forms of instruction. Accuracy of the target form was measured by two distinct tasks of sentence combining test and grammaticality judgment test.Findings and Results: The results of the two tests show improvement of all three groups, the focus on form treatment group outperformed the other two on both tests, however. This study also suggests that learners’ attention to detailed analysis of form facilitates the learning of relative clauses in this context.

  12. Evaluation of Computer-Assisted Instruction in Principles of Economics

    Directory of Open Access Journals (Sweden)

    Dennis Coates


    Full Text Available Despite increasing use, little is known about the effectiveness of web-based instructional material. This study assesses the effectiveness of supplementary web-based materials and activities in introductory economics courses. We have collected data on 66 students from three principles sections that describe demographic characteristics, use of web-based instructional resources, and performance on graded quizzes and examinations. We use this data to statistically assess the effectiveness of the web-based material. Student utilization of web-based material was extensive. Students frequently used on-line practice quizzes and accessed the web-based material often. A sizable fraction of the students actively posted and read threaded discussions on the course bulletin board. The statistical analysis shows that both on-line computer graded practice quizzes and posting to the class bulletin board are positively correlated with student performance on the quizzes and exams, but use of web-based content and passive reading of bulletin board posts ("lurking" is not. These results suggest that faculty should focus more on developing self-test quizzes and effective bulletin board discussion projects and less on generating on-line content.

  13. TEACHING IN ONLINE COURSES: Experiences of Instructional Technology Faculty Members

    Directory of Open Access Journals (Sweden)

    Omur AKDEMIR


    Full Text Available The Internet and computer technology have altered the education landscape. Online courses are offered throughout the world. Learning about the experiences of faculty members is important to guide practitioners and administrators. Using qualitative research methodology, this study investigated the experiences of faculty members teaching online courses. A convenience sampling was used to select the instructional technology faculty members to investigate their experiences in online courses. Semi-structured interviews with faculty members teaching online courses were used as the primary source to collect data about the experiences of faculty members in online courses. Results of the study showed that faculty members' interest in using technology and the amount of time available to them for online course design affected the quality of online courses. The findings of this study also indicated that design quality of online courses is affected by the interest of faculty members to use the technology and the time that they can devote to planning, designing, and developing online courses. The poor design of existing online courses, high learning expectations of ndividuals from these courses, and the future of online courses are the concerns of faculty members. Higher education institutions should support workshops and trainings to increase the skills and interests of non-instructional design faculty members to design and develop online courses.

  15. Intelligibility of clear speech: effect of instruction. (United States)

    Lam, Jennifer; Tjaden, Kris


    The authors investigated how clear speech instructions influence sentence intelligibility. Twelve speakers produced sentences in habitual, clear, hearing impaired, and overenunciate conditions. Stimuli were amplitude normalized and mixed with multitalker babble for orthographic transcription by 40 listeners. The main analysis investigated percentage-correct intelligibility scores as a function of the 4 conditions and speaker sex. Additional analyses included listener response variability, individual speaker trends, and an alternate intelligibility measure: proportion of content words correct. Relative to the habitual condition, the overenunciate condition was associated with the greatest intelligibility benefit, followed by the hearing impaired and clear conditions. Ten speakers followed this trend. The results indicated different patterns of clear speech benefit for male and female speakers. Greater listener variability was observed for speakers with inherently low habitual intelligibility compared to speakers with inherently high habitual intelligibility. Stable proportions of content words were observed across conditions. Clear speech instructions affected the magnitude of the intelligibility benefit. The instruction to overenunciate may be most effective in clear speech training programs. The findings may help explain the range of clear speech intelligibility benefit previously reported. Listener variability analyses suggested the importance of obtaining multiple listener judgments of intelligibility, especially for speakers with inherently low habitual intelligibility.

  16. Traditional microscopy instruction versus process-oriented virtual microscopy instruction: a naturalistic experiment with control group. (United States)

    Helle, Laura; Nivala, Markus; Kronqvist, Pauliina; Gegenfurtner, Andreas; Björk, Pasi; Säljö, Roger


    Virtual microscopy is being introduced in medical education as an approach for learning how to interpret information in microscopic specimens. It is, however, far from evident how to incorporate its use into existing teaching practice. The aim of the study was to explore the consequences of introducing virtual microscopy tasks into an undergraduate pathology course in an attempt to render the instruction more process-oriented. The research questions were: 1) How is virtual microscopy perceived by students? 2) Does work on virtual microscopy tasks contribute to improvement in performance in microscopic pathology in comparison with attending assistant-led demonstrations only? During a one-week period, an experimental group completed three sets of virtual microscopy homework assignments in addition to attending demonstrations. A control group attended the demonstrations only. Performance in microscopic pathology was measured by a pre-test and a post-test. Student perceptions of regular instruction and virtual microscopy were collected one month later by administering the Inventory of Intrinsic Motivation and open-ended questions. The students voiced an appreciation for virtual microscopy for the purposes of the course and for self-study. As for learning gains, the results indicated that learning was speeded up in a subgroup of students consisting of conscientious high achievers. The enriched instruction model may be suited as such for elective courses following the basic course. However, the instructional model needs further development to be suited for basic courses.

  17. Identifying Keys to Success in Innovative Teaching: Student Engagement and Instructional Practices as Predictors of Student Learning in a Course Using a Team-Based Learning Approach

    Directory of Open Access Journals (Sweden)

    Rosa M. Alvarez-Bell


    Full Text Available When implementing innovative teaching techniques, instructors often seek to gauge the success of their methods. Proposing one approach to assessing classroom innovation, this study examines the ability of students’ ratings of engagement and instructional practices to predict their learning in a cooperative (team-based framework. After identifying the factor structures underlying measures of student engagement and instructional practices, these factors were used as predictors of self-reported student learning in a general chemistry course delivered using a team-based learning approach. Exploratory factor analyses showed a four-factor structure of engagement: teamwork involvement, investment in the learning process, feelings about team-based learning, level of academic challenge; and a three-factor structure of instructional practices: instructional guidance, fostering self-directed learning skills, and cognitive level. Multiple linear regression revealed that feelings about team-based learning and perceptions of instructional guidance had significant effects on learning, beyond other predictors, while controlling gender, GPA, class level, number of credit hours, whether students began college at their current institution, expected highest level of education, racial or ethnic identification, and parental level of education. These results yield insight into student perceptions about team-based learning, and how to measure learning in a team-based learning framework, with implications for how to evaluate innovative instructional methods.

  18. Benefits of Instructed Responding in Manual Assembly Tasks: An ERP Approach

    Directory of Open Access Journals (Sweden)

    Pavle eMijović


    Full Text Available The majority of neuroergonomics studies are focused mainly on investigating the interaction between operators and automated systems. Far less attention has been dedicated to the investigation of brain processes in more traditional workplaces, such as manual assembly, which are still ubiquitous in industry. The present study investigates whether assembly workers’ attention can be enhanced if they are instructed with which hand to initiate the assembly operation, as opposed to the case when they can commence the operation with whichever hand they prefer. For this aim, we replicated a specific workplace, where seventeen participants in the study simulated a manual assembly operation of the rubber hoses that are used in vehicle hydraulic brake systems, while wearing wireless electroencephalography (EEG. The specific EEG feature of interest for this study was the P300 components’ amplitude of the event-related potential (ERP, as it has previously been shown that it is positively related to human attention. The behavioral attention-related modality of reaction times (RTs was also recorded. Participants were presented with two distinct tasks during the simulated operation, which were counterbalanced across participants. In the first task, digits were used as indicators for the operation initiation (Numbers task, where participants could freely choose with which hand they would commence the action upon seeing the digit. In the second task, participants were presented with arrows, which served as instructed operation initiators (Arrows task, and they were instructed to start each operation with the hand that corresponded to the arrow direction. The results of this study showed that the P300 amplitude was significantly higher in the instructed condition. Interestingly, the RTs did not differ across any task conditions. This, together with the other findings of this study, suggests that attention levels can be increased using instructed responses

  19. Instructional strategies for online introductory college physics based on learning styles (United States)

    Ekwue, Eleazer U.

    The practical nature of physics and its reliance on mathematical presentations and problem solving pose a challenge toward presentation of the course in an online environment for effective learning experience. Most first-time introductory college physics students fail to grasp the basic concepts of the course and the problem solving skills if the instructional strategy used to deliver the course is not compatible with the learners' preferred learning styles. This study investigates the effect of four instructional strategies based on four learning styles (listening, reading, iconic, and direct-experience) to improve learning for introductory college physics in an online environment. Learning styles of 146 participants were determined with Canfield Learning Style inventory. Of the 85 learners who completed the study, research results showed a statistically significant increase in learning performance following the online instruction in all four learning style groups. No statistically significant differences in learning were found among the four groups. However, greater significant academic improvement was found among learners with iconic and direct-experience modes of learning. Learners in all four groups expressed that the design of the unit presentation to match their individual learning styles contributed most to their learning experience. They were satisfied with learning a new physics concept online that, in their opinion, is either comparable or better than an instructor-led classroom experience. Findings from this study suggest that learners' performance and satisfaction in an online introductory physics course could be improved by using instructional designs that are tailored to learners' preferred ways of learning. It could contribute toward the challenge of providing viable online physics instruction in colleges and universities.

  1. Computer Instruction in Handwriting, Spelling, and Composing for Students with Specific Learning Disabilities in Grades 4 to 9. (United States)

    Berninger, Virginia W; Nagy, William; Tanimoto, Steve; Thompson, Rob; Abbott, Robert D


    Effectiveness of iPad computerized writing instruction was evaluated for 4 th to 9 th graders ( n =35) with diagnosed specific learning disabilities (SLDs) affecting writing: dysgraphia (impaired handwriting), dyslexia (impaired spelling), and oral and written language learning disability (OWL LD) (impaired syntax composing). Each of the 18 two-hour lessons had multiple learning activities aimed at improving subword - (handwriting), word - (spelling), and syntax - (sentence composing) level language skills by engaging all four language systems (listening, speaking, reading, and writing) to create a functional writing system. To evaluate treatment effectiveness, normed measures of handwriting, spelling, and composing were used with the exception of one non-normed alphabet writing task. Results showed that the sample as a whole improved significantly from pretest to posttest in three handwriting measures, four spelling measures, and both written and oral syntax construction measures. All but oral syntax was evaluated with pen and paper tasks, showing that the computer writing instruction transferred to better writing with pen and paper. Performance on learning activities during instruction correlated with writing outcomes; and individual students tended to improve in the impaired skill associated with their diagnosis. Thus, although computers are often used in upper elementary school and middle school in the United States (US) for accommodations (alternatives to pen and paper) for students with persisting SLDs affecting writing, this study shows computers can also be used for Tier 3 instruction to improve the writing skills of students in grades 4 to 9 with history of persisting writing disabilities.

  2. Computer Instruction in Handwriting, Spelling, and Composing for Students with Specific Learning Disabilities in Grades 4 to 9 (United States)

    Berninger, Virginia W.; Nagy, William; Tanimoto, Steve; Thompson, Rob; Abbott, Robert D.


    Effectiveness of iPad computerized writing instruction was evaluated for 4th to 9th graders (n=35) with diagnosed specific learning disabilities (SLDs) affecting writing: dysgraphia (impaired handwriting), dyslexia (impaired spelling), and oral and written language learning disability (OWL LD) (impaired syntax composing). Each of the 18 two-hour lessons had multiple learning activities aimed at improving subword- (handwriting), word- (spelling), and syntax- (sentence composing) level language skills by engaging all four language systems (listening, speaking, reading, and writing) to create a functional writing system. To evaluate treatment effectiveness, normed measures of handwriting, spelling, and composing were used with the exception of one non-normed alphabet writing task. Results showed that the sample as a whole improved significantly from pretest to posttest in three handwriting measures, four spelling measures, and both written and oral syntax construction measures.

  4. Effects of instructions and cue subjectiveness on specificity of autobiographical memory recall

    Directory of Open Access Journals (Sweden)

    Jorge J. Ricarte-Trives


    Full Text Available The first aim of this study was to determine the power of instructions on the specificity of autobiographical memory as obtained with the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986 and the efficacy of cue word criteria selection based on subjective parameters obtained with a standardized lexical program. Results showed a high power of specific instructions in its written version in contrast to non-directed memory recall to the same list of words three weeks later in a counterbalanced repeated measures within-subjects design. This effect was stronger when subjects previously were faced to the non-specific recovery task. Matched word lists using the "Buscapalabras" program (Davis & Perea, 2005 showed a very similar behaviour. These results point out that the same stimuli can be used repeatedly to obtain voluntary and involuntary retrieval with changes at instructional level. Additionally, standardized lexical programs can be employed to adapt cue-words of memory recall systems controlling for subjective differences related to language parameters (frequency, imageability and familiarity.

  5. Cooperative learning as applied to resident instruction in radiology reporting. (United States)

    Mueller, Donald; Georges, Alexandra; Vaslow, Dale


    The study is designed to evaluate the effectiveness of an active form of resident instruction, cooperative learning, and the residents' response to that form of instruction. The residents dictated three sets of reports both before and after instruction in radiology reporting using the cooperative learning method. The reports were evaluated for word count, Flesch-Kincaid grade level, advancement on clinical spectrum, clarity, and comparison to prior reports. The reports were evaluated for changes in performance characteristics between the pre- and postinstruction dictations. The residents' response to this form of instruction was evaluated by means of a questionnaire. The instruction was effective in changing the resident dictations. The results became shorter (Pcooperative learning activities. The least positive responses related to the amount of time devoted to the project. Sixty-three percent of respondents stated that the time devoted to the project was appropriate. Cooperative learning can be an effective tool in the setting of the radiology residency. Instructional time requirements must be strongly considered in designing a cooperative learning program.

  6. Invention Versus Direct Instruction: For Some Content, It's a Tie (United States)

    Chase, Catherine C.; Klahr, David


    An important, but as yet unresolved pedagogical question is whether discovery-oriented or direct instruction methods lead to greater learning and transfer. We address this issue in a study with 101 fourth and fifth grade students that contrasts two distinct instructional methods. One is a blend of discovery and direct instruction called Invent-then-Tell (IT), and the other is a version of direct instruction called Tell-then-Practice (TP). The relative effectiveness of these methods is compared in the context of learning a critical inquiry skill—the control-of-variables strategy. Previous research has demonstrated the success of IT over TP for teaching deep domain structures, while other research has demonstrated the superiority of direct instruction for teaching simple experimental design, a domain-general inquiry skill. In the present study, students in both conditions made equally large gains on an immediate assessment of their application and conceptual understanding of experimental design, and they also performed similarly on a test of far transfer. These results were fairly consistent across school populations with various levels of prior achievement and socioeconomic status. Findings suggest that broad claims about the relative effectiveness of these two distinct methods should be conditionalized by particular instructional contexts, such as the type of knowledge being taught.

  7. Biased lineup instructions and face identification from video images. (United States)

    Thompson, W Burt; Johnson, Jaime


    Previous eyewitness memory research has shown that biased lineup instructions reduce identification accuracy, primarily by increasing false-positive identifications in target-absent lineups. Because some attempts at identification do not rely on a witness's memory of the perpetrator but instead involve matching photos to images on surveillance video, the authors investigated the effects of biased instructions on identification accuracy in a matching task. In Experiment 1, biased instructions did not affect the overall accuracy of participants who used video images as an identification aid, but nearly all correct decisions occurred with target-present photo spreads. Both biased and unbiased instructions resulted in high false-positive rates. In Experiment 2, which focused on video-photo matching accuracy with target-absent photo spreads, unbiased instructions led to more correct responses (i.e., fewer false positives). These findings suggest that investigators should not relax precautions against biased instructions when people attempt to match photos to an unfamiliar person recorded on video.

During four weeks, university learners of French received MI on the distinctive use of the perfective and the imperfective past in one of the four following conditions: learners with low L2 proficiency level exposed to MI with (n=17 or without language awareness tasks (n=17, and learners with intermediate L2 proficiency level exposed to MI with (n=14 or without language awareness tasks (n=28. Before and after the experiment, participants completed the Attitude/Motivation Test Battery (AMTB. Non-parametric analyses revealed a positive enhancement of classroom-related attitudes only among intermediate learners exposed to MI without Language Awareness Tasks. Nevertheless, the results showed similar as well as stable attitudes towards language learning in all the experimental conditions.

  9. Expanding Library Services and Instruction Through LibGuides. (United States)

    Ream, Tim; Parker-Kelly, Darlene


    Beginning in 2012, the Charles R. Drew University (CDU) Health Sciences Library used LibGuides in a number of innovative ways. Librarians constructed e-book databases, in-depth tutorials on technology-related topics, and web pages highlighting special events. To assess similar LibGuides innovation, CDU librarians developed an eight-question survey distributed to health sciences and hospital libraries throughout Southern California and Arizona. Results showed that libraries used LibGuides primarily to deliver access to online resources and to provide supplementary materials supporting instruction. Responses also revealed that many libraries had not yet adopted LibGuides. These findings were analyzed and compared to past and current LibGuides design at CDU.

  15. Unconscious learning processes: mental integration of verbal and pictorial instructional materials. (United States)

    Kuldas, Seffetullah; Ismail, Hairul Nizam; Hashim, Shahabuddin; Bakar, Zainudin Abu


    This review aims to provide an insight into human learning processes by examining the role of cognitive and emotional unconscious processing in mentally integrating visual and verbal instructional materials. Reviewed literature shows that conscious mental integration does not happen all the time, nor does it necessarily result in optimal learning. Students of all ages and levels of experience cannot always have conscious awareness, control, and the intention to learn or promptly and continually organize perceptual, cognitive, and emotional processes of learning. This review suggests considering the role of unconscious learning processes to enhance the understanding of how students form or activate mental associations between verbal and pictorial information. The understanding would assist in presenting students with spatially-integrated verbal and pictorial instructional materials as a way of facilitating mental integration and improving teaching and learning performance.

  16. A Review of What Instructional Designers Do: Questions Answered and Questions Not Asked

    Directory of Open Access Journals (Sweden)

    Richard Kenny


    Full Text Available The purpose of this literature review was to determine what evidence there is that instructional designers apply ID Models, as well as to establish what other activities and processes they might use in their professional activities. Only ten articles were located that directly pertained to this topic: seven reporting on empirical research and three case descriptions recounting development experiences. All ten papers pertained to process-based ID models. Results showed that, while instructional designers apparently do make use of process-based ID models, they do not spend the majority of their time working with them nor do they follow them in a rigid fashion. They also engage in a wide variety of other tasks that are not reflected in ID models.

  17. Instructional climates in preschool children who are at-risk. Part II: perceived physical competence. (United States)

    Robinson, Leah E; Rudisill, Mary E; Goodway, Jacqueline D


    In Part II of this study, we examined the effect of two 9-week instructional climates (low-autonomy [LA] and mastery motivational climate [MMC]) on perceived physical competence (PPC) in preschoolers (N = 117). Participants were randomly assigned to an LA, MMC, or comparison group. PPC was assessed by a pretest, posttest, and retention test with the Pictorial Scale of Perceived Competence and Social Acceptance. A significant Treatment x Time interaction (p < .001) was present, supporting that MMC participants reported significantly higher PPC scores over time, while no positive changes were present in LA and comparison participants. The results show that an MMC leads to psychological benefits related to achievement motivation. These findings should encourage early childhood educators to consider the effect of instructional climates on children's self-perception.

  18. The impact of whole-plant instruction of preservice teachers' understanding of plant science principles (United States)

    Hypolite, Christine Collins

    The purpose of this research was to determine how an inquiry-based, whole-plant instructional strategy would affect preservice elementary teachers' understanding of plant science principles. This study probed: what preservice teachers know about plant biology concepts before and after instruction, their views of the interrelatedness of plant parts and the environment, how growing a plant affects preservice teachers' understanding, and which types of activity-rich plant themes studies, if any, affect preservice elementary teachers' understandings. The participants in the study were enrolled in two elementary science methods class sections at a state university. Each group was administered a preinstructional test at the beginning of the study. The treatment group participated in inquiry-based activities related to the Principles of Plant Biology (American Society of Plant Biologists, 2001), while the comparison group studied those same concepts through traditional instructional methods. A focus group was formed from the treatment group to participate in co-concept mapping sessions. The participants' understandings were assessed through artifacts from activities, a comparison of pre- and postinstructional tests, and the concept maps generated by the focus group. Results of the research indicated that the whole-plant, inquiry-based instructional strategy can be applied to teach preservice elementary teachers plant biology while modeling the human constructivist approach. The results further indicated that this approach enhanced their understanding of plant science content knowledge, as well as pedagogical knowledge. The results also showed that a whole-plant approach to teaching plant science concepts is an instructional strategy that is feasible for the elementary school. The theoretical framework for this study was Human Constructivist learning theory (Mintzes & Wandersee, 1998). The content knowledge and instructional strategy was informed by the Principles of Plant

  19. Documenting Instructional Practices in Large Introductory STEM Lecture Courses (United States)

    Vu, Viet Quoc

    STEM education reform in higher education is framed around the need to improve student learning outcomes, increase student retention, and increase the number of underrepresented minorities and female students in STEM fields, all of which would ultimately contribute to America's competitiveness and prosperity. To achieve these goals, education reformers call for an increase in the adoption of research-based "promising practices" in classrooms. Despite efforts to increase the adoption of more promising practices in classrooms, postsecondary instructors are still likely to lecture and use traditional teaching approaches. To shed light on this adoption dilemma, a mix-methods study was conducted. First, instructional practices in large introductory STEM courses were identified, followed by an analysis of factors that inhibit or contribute to the use of promising practices. Data were obtained from classroom observations (N = 259) of large gateway courses across STEM departments and from instructor interviews (N = 67). Results show that instructors are already aware of promising practices and that change strategies could move from focusing on the development and dissemination of promising practices to focusing on improving adoption rates. Teaching-track instructors such as lecturers with potential for security of employment (LPSOE) and lecturers with security of employment (LSOE) have adopted promising practices more than other instructors. Interview data show that LPSOEs are also effective at disseminating promising practices to their peers, but opinion leaders (influential faculty in a department) are necessary to promote adoption of promising practices by higher ranking instructors. However, hiring more LPSOEs or opinion leaders will not be enough to shift instructional practices. Variations in the adoption of promising practices by instructors and across departments show that any reform strategy needs to be systematic and take into consideration how information is

  4. An Evaluation of Instructive Feedback to Teach Play Behavior to a Child with Autism Spectrum Disorder. (United States)

    Grow, Laura L; Kodak, Tiffany; Clements, Andrea


    Instructive feedback is used to expose learners to secondary targets during skill acquisition programs (Reichow & Wolery, in Journal of Applied Behavior Analysis, 44 , 327-340, 2011; Werts, Wolery, Gast, & Holcombe, in Journal of Behavioral Education, 5 , 55-75, 1995). Although unrelated feedback may have clinical utility in practice, very little research has evaluated unrelated instructive feedback, particularly for promoting play behavior (Colozzi, Ward, & Crotty, in Education and Training in Developmental Disabilities, 43 , 226-248, 2008). The purpose of the study was to determine if play emerged after embedding instructive feedback during the consequence portion of discrete trial training to teach tacts. An adapted alternating treatments design was used to compare tact training with and without instructive feedback for play behaviors. Instructive feedback resulted in the emergence of play behaviors during tabletop instruction and a play area of a classroom. We discuss the results in terms of clinical practice and future research.

  1. The double-edged sword of pedagogy: Instruction limits spontaneous exploration and discovery. (United States)

    Bonawitz, Elizabeth; Shafto, Patrick; Gweon, Hyowon; Goodman, Noah D; Spelke, Elizabeth; Schulz, Laura


    Motivated by computational analyses, we look at how teaching affects exploration and discovery. In Experiment 1, we investigated children's exploratory play after an adult pedagogically demonstrated a function of a toy, after an interrupted pedagogical demonstration, after a naïve adult demonstrated the function, and at baseline. Preschoolers in the pedagogical condition focused almost exclusively on the target function; by contrast, children in the other conditions explored broadly. In Experiment 2, we show that children restrict their exploration both after direct instruction to themselves and after overhearing direct instruction given to another child; they do not show this constraint after observing direct instruction given to an adult or after observing a non-pedagogical intentional action. We discuss these findings as the result of rational inductive biases. In pedagogical contexts, a teacher's failure to provide evidence for additional functions provides evidence for their absence; such contexts generalize from child to child (because children are likely to have comparable states of knowledge) but not from adult to child. Thus, pedagogy promotes efficient learning but at a cost: children are less likely to perform potentially irrelevant actions but also less likely to discover novel information. Copyright © 2010.

  3. The impact of high-stakes, state-mandated student performance assessment on 10th grade English, mathematics, and science teachers' instructional practices (United States)

    Vogler, Kenneth E.

    The purpose of this study was to determine if the public release of student results on high-stakes, state-mandated performance assessments influence instructional practices, and if so in what manner. The research focused on changes in teachers' instructional practices and factors that may have influenced such changes since the public release of high-stakes, state-mandated student performance assessment scores. The data for this study were obtained from a 54-question survey instrument given to a stratified random sample of teachers teaching at least one section of 10th grade English, mathematics, or science in an academic public high school within Massachusetts. Two hundred and fifty-seven (257) teachers, or 62% of the total sample, completed the survey instrument. An analysis of the data found that teachers are making changes in their instructional practices. The data show notable increases in the use of open-response questions, creative/critical thinking questions, problem-solving activities, use of rubrics or scoring guides, writing assignments, and inquiry/investigation. Teachers also have decreased the use of multiple-choice and true-false questions, textbook-based assignments, and lecturing. Also, the data show that teachers felt that changes made in their instructional practices were most influenced by an "interest in helping my students attain MCAS assessment scores that will allow them to graduate high school" and by an "interest in helping my school improve student (MCAS) assessment scores," Finally, mathematics teachers and teachers with 13--19 years of experience report making significantly more changes than did others. It may be interpreted from the data that the use of state-mandated student performance assessments and the high-stakes attached to this type of testing program contributed to changes in teachers' instructional practices. The changes in teachers' instructional practices have included increases in the use of instructional practices deemed

  4. Inquiry-Based Instruction and High Stakes Testing (United States)

    Cothern, Rebecca L.

    Science education is a key to economic success for a country in terms of promoting advances in national industry and technology and maximizing competitive advantage in a global marketplace. The December 2010 Program for International Student Assessment (PISA) ranked the United States 23rd of 65 countries in science. That dismal standing in science proficiency impedes the ability of American school graduates to compete in the global market place. Furthermore, the implementation of high stakes testing in science mandated by the 2007 No Child Left Behind (NCLB) Act has created an additional need for educators to find effective science pedagogy. Research has shown that inquiry-based science instruction is one of the predominant science instructional methods. Inquiry-based instruction is a multifaceted teaching method with its theoretical foundation in constructivism. A correlational survey research design was used to determine the relationship between levels of inquiry-based science instruction and student performance on a standardized state science test. A self-report survey, using a Likert-type scale, was completed by 26 fifth grade teachers. Participants' responses were analyzed and grouped as high, medium, or low level inquiry instruction. The unit of analysis for the achievement variable was the student scale score average from the state science test. Spearman's Rho correlation data showed a positive relationship between the level of inquiry-based instruction and student achievement on the state assessment. The findings can assist teachers and administrators by providing additional research on the benefits of the inquiry-based instructional method. Implications for positive social change include increases in student proficiency and decision-making skills related to science policy issues which can help make them more competitive in the global marketplace.

  5. Student performance on conceptual questions: Does instruction matter? (United States)

    Heron, Paula R. L.


    As part of the tutorial component of introductory calculus-based physics at the University of Washington, students take weekly pretests that consist of conceptual questions. Pretests are so named because they precede each tutorial, but they are frequently administered after lecture instruction. Many variables associated with class composition and prior instruction (if any) could, in principle, affect student performance on these questions. Nonetheless, the results are often found to be "essentially the same" in all classes. With data available from a large number of classes, it is possible to characterize the typical variation quantitatively. In this paper three questions for which we have accumulated thousands of responses, from dozens of classes representing different conditions with respect to the textbook in use, the amount of prior instruction, etc., serve as examples. For each question, we examine the variation in student performance across all classes. We also compare subsets categorized according to the amount of relevant prior instruction each class had received. A preliminary analysis suggests that the variation in performance is essentially random. No statistically significant difference is observed between results obtained before relevant instruction begins and after it has been completed. The results provide evidence that exposure to concepts in lecture and textbook is not sufficient to ensure an improvement in performance on questions that require qualitative reasoning.

    OBJECTIVE To develop a typology of after-hours care (AHC) instructions and to examine physician and practice characteristics associated with each type of instruction. DESIGN Cross-sectional telephone survey. Physicians’ offices were called during evenings and weekends to listen to their messages regarding AHC. All messages were categorized. Thematic analysis of a subset of messages was conducted to develop a typology of AHC instructions. Logistic regression analysis was used to identify associations between physician and practice characteristics and the instructions left for patients. SETTING Family practices in the greater Toronto area. PARTICIPANTS Stratified random sample of family physicians providing office-based primary care. MAIN OUTCOME MEASURES Form of response (eg, answering machine), content of message, and physician and practice characteristics. RESULTS Of 514 after-hours messages from family physicians’ offices, 421 were obtained from answering machines, 58 were obtained from answering services, 23 had no answer, 2 gave pager numbers, and 10 had other responses. Message content ranged from no AHC instructions to detailed advice; 54% of messages provided a single instruction, and the rest provided a combination of instructions. Content analysis identified 815 discrete instructions or types of response that were classified into 7 categories: 302 instructed patients to go to an emergency department; 122 provided direct contact with a physician; 115 told patients to go to a clinic; 94 left no directions; 76 suggested calling a housecall service; 45 suggested calling Telehealth; and 61 suggested other things. About 22% of messages only advised attending an emergency department, and 18% gave no advice at all. Physicians who were female, had Canadian certification in family medicine, held hospital privileges, or had attended a Canadian medical school were more likely to be directly available to their patients. CONCLUSION Important issues identified

    International Nuclear Information System (INIS)

    Yim, Ho Bin


    As industrial plants and factories age, their maintenance requirements increase. Because maintenance mistakes directly increase the operating costs of a power plant, maintenance quality is of significant concern to plant management. By law, all personnel working with nuclear technology must be re-trained every three years; however, as the statistical data show, the number of shutdown accidents at nuclear power plants (NPPs) due to maintenance failure is still high and needs to be reduced. Industries have started to adopt various technologies to increase the speed and accuracy of maintenance. Among those technologies, augmented reality (AR) is the latest multimedia presentation technology to be applied to plant maintenance, and it offers superior intuitiveness and user interactivity over other conventional multimedia. The objectives of this empirical study are to measure the optimum amounts of information to be delivered at a time and to identify what types of information enhance the learning ability of novices and to suggest heuristic guidelines by which to make effective AR training instructions. In addition, AR training instructions will be composed based on the suggested heuristic guidelines and on the Cognitive Theory of Multimedia Learning, which provides guidelines for multimedia instructions, and the efficiency of those guidelines will be compared with that of other AR instructions. Cognitive Load Theory addresses how working memory is structured. Intrinsic cognitive load refers to the cognitive load that is inherent in information to be learned. It depends on the basic amount of processing required for understanding a presentation. Intrinsic cognitive load is determined by the complexity of the learning material. Extraneous cognitive load refers to the cognitive load created through the presentation, format and delivery of the instruction. Germane cognitive load is the remaining part of the cognitive load, and it helps the learner transfer information from

    Full Text Available This study was designed to investigate the effects of age of onset and type of instruction on ultimate EFL attainment at the end of the period of normal schooling in Switzerland, measured in terms of written fluency, complexity, morphosyntactic accuracy, vocabulary size, and listening skills. Data were gathered from four groups of 18-year-old Swiss German learners of English: 50 were early starters who had attended an immersion (CLIL program in elementary school and who continued CLIL in secondary school (EARLY CLIL, 50 had followed the same elementary school program but then received traditional EFL instruction after elementary school (EARLY MIX, 50 were late starters who began learning English immersively in secondary school, (LATE CLIL, while the other 50 attended a traditional EFL program in secondary school (LATE NON-CLIL. Results show that age of onset alone does not seem to be the distinguishing variable since early introduction of English in elementary school did not result in a higher level of roficiency when exposure to the language was limited to a few hours of class per week. The performance of the EARLY MIX participants was equaled and in certain areas significantly surpassed by the other groups, despite the additional five years of English study they had had in elementary school. The best results were found when early CLIL instruction was followed up by the use of English as an additional language of instruction in secondary school (EARLY CLIL group, which confirms the link between young starting age, implicit learning and long and massive exposure.

  12. Instructional design in mathematics for undergraduate students based on learning by mistakes approach utilizing scilab assistance (United States)

    Kartika, H.


    The issue related to making mistake while learning such as negative emotion is found while students learn mathematics with the aid of a computer. When the computer output showed a mistake message, the students considered it as a computer software malfunction. Based on this issue, the writer designs an instructional model based on learning by mistake approach and which is Scilab assisted. The method used in this research is research design involving undergraduate students in matrix algebra courses. The data collected throught survey with questionnaire to gain feedback about the approach implemented. The data analyzed using quantitative descriptive. The instructional design proposed is the student act as a mistake corrector while the teacher acts as a mistake maker. Teacher deliberately makes mistakes with the help of Scilab software. On the other hand, students correct, analyze and explain errors resulting from Scilab software. The result of this research is an ICT based instructional design which is expected to be applicable as an alternative learning in directing students to think positively about mistakes in learning. Furthermore, students are also expected to improve their ability in understanding and thinking critically while solving problems and improving themselves in learning mathematics.

A combination of the two methods is clearly the ideal solution when teaching astronomy to middle school students in a Starlab setting.

  15. Constructivist Instructional Practices and Teacher Beliefs Related to Secondary Science Teaching and Learning (United States)

    Nelson, Adrienne Fleurette

    The purpose of this mixed method research study was to examine the constructivist beliefs and instructional practices of secondary science teachers. The research also explored situations that impacted whether or not student centered instruction occurred. The study revealed science teachers held constructive beliefs pertaining to student questioning of the learning process and student autonomy in interacting with other learners. Teachers held the least constructivist beliefs pertaining to student teacher collaboration on lesson design. Additionally, teacher beliefs and practice were not congruent due to instructional practices being deemed less constructivist than reported. The study found that curricular demands, teacher perceptions about students, inadequate laboratory resources, and the lack of teacher understanding about the components of constructivist instruction inhibited student centered instruction. The results of this study led to six recommendations that can be implemented by school districts in collaboration with science teachers to promote constructivist instruction.

  16. Instructional Leadership and Schools Effectiveness (United States)

    Hung, Daisy Kee Mui; Ponnusamy, Premavathy

    With the influx of information technology through the Internet and the use of ICT in our daily lives, our future generation has traversed from a mere change of era to a dynamic era of change. Thus, the role of school leaders is becoming more challenging than ever. They need to make greater strides to ensure that they are able to make adjustments and readjustments in instructional practices to cater for the changing elements in their organization. In brief, the school leaders have to be creative, innovative with entrepreneurial drive in order to steer their subordinates (teachers) towards school excellence. Leadership of principal is therefore considered as a main criterion to create successful schools in country's educational advancement. Besides, the school effectiveness plays a crucial role in country's academic advancement. This paper focuses on a comprehensive review of literature on the relationship between instructional leadership and school effectiveness.

  17. Collaboration systems for classroom instruction (United States)

    Chen, C. Y. Roger; Meliksetian, Dikran S.; Chang, Martin C.


    In this paper we discuss how classroom instruction can benefit from state-of-the-art technologies in networks, worldwide web access through Internet, multimedia, databases, and computing. Functional requirements for establishing such a high-tech classroom are identified, followed by descriptions of our current experimental implementations. The focus of the paper is on the capabilities of distributed collaboration, which supports both synchronous multimedia information sharing as well as a shared work environment for distributed teamwork and group decision making. Our ultimate goal is to achieve the concept of 'living world in a classroom' such that live and dynamic up-to-date information and material from all over the world can be integrated into classroom instruction on a real-time basis. We describe how we incorporate application developments in a geography study tool, worldwide web information retrievals, databases, and programming environments into the collaborative system.

  18. Sport Education and Direct Instruction Units: Comparison of Student Knowledge Development in Athletics (United States)

    Pereira, José; Araújo, Rui; Farias, Cláudio; Bessa, Cristiana; Mesquita, Isabel


    This study conducted a comparative analysis of students’ knowledge development on athletics in Sport Education and in a Direct Instruction unit taking into account sex and initial skill level. The participants were an experienced Physical Education teacher and two sixth-grade classes totaling 47 students (25 boys and 22 girls). Each class was randomly placed in either Sport Education or Direct Instruction classes and participated in 20, 45-minutes lessons focused on shot put, hurdles and triple jump. Knowledge on athletics was assessed through a 25-items written and video-based test. The inter-group differences and improvements across time in the knowledge test were analyzed through the Mann-Whitney and Wilcoxon tests, respectively. There were significant knowledge improvements in both instructional approaches irrespective of students’ gender and skill level. In Direct Instruction, the type of task organization, the high rates of repetition of movement patterns and feedback by the teacher were beneficial to student learning. In Sport Education, the autonomy granted to students in the control of the pace of task transitions by making on-going judgments on achievement of performance criteria, implicated students affectively and cognitively with the learning content. It was further supported that several models and teaching strategies should be taken into consideration when teaching Physical Education. Different approaches should be perceived as alternatives and teachers should retain the best in each according with the moment in the unit, student developmental stage, and the specific learning objectives in the task. Key points The results in this study showed that regardless of students’ sex, both DI and SE were efficient in the promotion of improvements in students’ content knowledge of athletics. Both boys and girls improved from the pre-test to the post-test in SE and DI. SE was particularly beneficial to lower skill-level. On the contrary, in the DI unit

  20. Using Technology to Facilitate Differentiated High School Science Instruction (United States)

    Maeng, Jennifer L.


    This qualitative investigation explored the beliefs and practices of one secondary science teacher, Diane, who differentiated instruction and studied how technology facilitated her differentiation. Diane was selected based on the results of a previous study, in which data indicated that Diane understood how to design and implement proactively planned, flexible, engaging instructional activities in response to students' learning needs better than the other study participants. Data for the present study included 3 h of semi-structured interview responses, 37.5 h of observations of science instruction, and other artifacts such as instructional materials. This variety of data allowed for triangulation of the evidence. Data were analyzed using a constant comparative approach. Results indicated that technology played an integral role in Diane's planning and implementation of differentiated science lessons. The technology-enhanced differentiated lessons employed by Diane typically attended to students' different learning profiles or interest through modification of process or product. This study provides practical strategies for science teachers beginning to differentiate instruction, and recommendations for science teacher educators and school and district administrators. Future research should explore student outcomes, supports for effective formative assessment, and technology-enhanced readiness differentiation among secondary science teachers.

  1. Instructional skills evaluation in nuclear industry training

    International Nuclear Information System (INIS)

    Mazour, T.J.; Ball, F.M.


    This report provides information to nuclear power plant training managers and their staffs concerning the job performance requirements of instructional personnel to implement prformance-based training programs (also referred to as the Systems Approach Training). The information presented in this report is a compilation of information and lessons learned in the nuclear power industry and in other industries using performance-based training programs. The job performance requirements in this report are presented as instructional skills objectives. The process used to develop the instructional skills objectives is described. Each objective includes an Instructional Skills Statement describing the behavior that is expected and an Instructional Skills Standard describing the skills/knowledge that the individual should possess in order to have achieved mastery. The instructional skills objectives are organized according to the essential elements of the Systems Approach to Training and are cross-referenced to three categories of instructional personnel: developers of instruction, instructors, and instructional managers/supervisors. Use of the instructional skills objectives is demonstrated for reviewing instructional staff training and qualification programs, developing criterion-tests, and reviewing the performance and work products of individual staff members. 22 refs

  2. Laboratory instruction and subjectivity

    Elisabeth Barolli


    Full Text Available The specific aspects which determined the way some groups of students conducted their work in a university laboratory, made us understand the articulation of these groups´s dynamics, from elements that were beyond the reach of cognition. In more specific terms the conduction and the maintenance of the groups student´s dynamics were explicited based on a intergame between the non conscious strategies, shared anonymously, and the efforts of the individuals in working based on their most objective task. The results and issues we have reached so far, using a reference the work developed by W.R.Bion, with therapeutical groups, gave us the possibility for understanding the dynamics of the student´s experimental work through a new approach that approximates the fields of cognition and subjectivity. This approximation led us to a deeper reflection about the issues which may be involved in the teaching process, particularly in situations which the teacher deals with the class, organised in groups.

  3. A Methodological Alternative to Media Comparison Studies: Linking Information Utilization Strategies and Instructional Approach in Hypermedia Learning


    Catrambone, Richard; Gerjets, Peter; Scheiter, Katharina; Vollmann, Brigitte


    Literature reviews on hypermedia learning have yet failed to show consistent positive effects of learner-controlled nonlinear information access. We argue that a possible reason for this lack of evidence in favor of hypermedia learning results from the fact that not sufficient attention is paid to the strategies of information utilization learners deploy. The few studies that do analyze these strategies fail to link them to an instructional approach, which hampers a deeper interpretation of s...

  4. Online Italian fandoms of American TV shows

    Directory of Open Access Journals (Sweden)

    Eleonora Benecchi


    Full Text Available The Internet has changed media fandom in two main ways: it helps fans connect with each other despite physical distance, leading to the formation of international fan communities; and it helps fans connect with the creators of the TV show, deepening the relationship between TV producers and international fandoms. To assess whether Italian fan communities active online are indeed part of transnational online communities and whether the Internet has actually altered their relationship with the creators of the original text they are devoted to, qualitative analysis and narrative interviews of 26 Italian fans of American TV shows were conducted to explore the fan-producer relationship. Results indicated that the online Italian fans surveyed preferred to stay local, rather than using geography-leveling online tools. Further, the sampled Italian fans' relationships with the show runners were mediated or even absent.

  5. Contrasting two models of academic self-efficacy--domain-specific versus cross-domain--in children receiving and not receiving special instruction in mathematics. (United States)

    Jungert, Tomas; Hesser, Hugo; Träff, Ulf


    In social cognitive theory, self-efficacy is domain-specific. An alternative model, the cross-domain influence model, would predict that self-efficacy beliefs in one domain might influence performance in other domains. Research has also found that children who receive special instruction are not good at estimating their performance. The aim was to test two models of how self-efficacy beliefs influence achievement, and to contrast children receiving special instruction in mathematics with normally-achieving children. The participants were 73 fifth-grade children who receive special instruction and 70 children who do not receive any special instruction. In year four and five, the children's skills in mathematics and reading were assessed by national curriculum tests, and in their fifth year, self-efficacy in mathematics and reading were measured. Structural equation modeling showed that in domains where children do not receive special instruction in mathematics, self-efficacy is a mediating variable between earlier and later achievement in the same domain. Achievement in mathematics was not mediated by self-efficacy in mathematics for children who receive special instruction. For normal achieving children, earlier achievement in the language domain had an influence on later self-efficacy in the mathematics domain, and self-efficacy beliefs in different domains were correlated. Self-efficacy is mostly domain specific, but may play a different role in academic performance depending on whether children receive special instruction. The results of the present study provided some support of the Cross-Domain Influence Model for normal achieving children. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  6. Learning and performance under alternative instructional manifestations of experimental practice (United States)

    Ford, Michael J.

    Before we can understand how students learn "to do" science, we must make explicit our assumptions about what scientific practice is. This study compares the learning outcomes of two sixth-grade instructional units on experimentation, each based on a particular characterization of practice. In one unit, instruction focused on acquisition and application of the control of variables strategy (CVS; Chen & Klahr, 1999), which is consistent with a popular conception of science education, stemming from Piaget, as the mastery of logical forms. In the other unit, students designed experimental apparatus to answer a target question, and instruction emphasized practices of rendering and transforming the material world in ways that support scientific understanding. Students in both groups were assessed for CVS acquisition and subsequent experimental performance on a novel task, and group performances on these assessments different across instructional conditions. I will argue that student understandings of goals, norms of instructional expectation, and strategies explain these differences, in some cases by supporting performance and in other cases by hindering it. I will also argue that the results question the role typically attributed to logical method in learning to design experiments.

    Data Systems Engineering Organization (DSEO) personnel developed a prototype computer aided instruction CAI system for the Naval Aviation Logistics Data Analysis (NALDA) system. The objective of this project was to provide a CAI prototype that could be used as an enhancement to existing NALDA training. The CAI prototype project was performed in phases. The task undertaken in Phase I was to analyze the problem and the alternative solutions and to develop a set of recommendations on how best to proceed. The findings from Phase I are documented in Recommended CAI Approach for the NALDA System (Duncan et al., 1987). In Phase II, a structured design and specifications were developed, and a prototype CAI system was created. A report, NALDA CAI Prototype: Phase II Final Report, was written to record the findings and results of Phase II. NALDA CAI: Recommendations for an Advanced Instructional Model, is comprised of related papers encompassing research on computer aided instruction CAI, newly developing training technologies, instructional systems development, and an Advanced Instructional Model. These topics were selected because of their relevancy to the CAI needs of NALDA. These papers provide general background information on various aspects of CAI and give a broad overview of new technologies and their impact on the future design and development of training programs.

    As a first step to realize an autonomous mobile robot for plant maintenance, where the robot is capable to understand instructions written in natural languages, we have developed a prototype of instruction understanding system which makes the robot construct its motion sequences to approach instrumentations and inspect them from input sentences written in Japanese. In the prototype system, the instruction understanding and planning capabilities are integrated by an inference engine which consists of a cyclic operation of three processings, i.e., sensing, decision, and execution. Based on environmental data and current states of the robot, a proper process such as natural language processing is triggered by the decision part of the inference engine to accomplish the input instructions. The multiple- and dynamic-planning capabilities, which are necessary to cope with dynamic changes of environments surrounding the robot, are achieved by utilizing the cyclic inference engine together with a set of the inference packets which keep intermediate results of natural language processing and planning for respective input instructions.

  9. Librarian instruction-delivery modality preferences for professional continuing education. (United States)

    Lynn, Valerie A; Bose, Arpita; Boehmer, Susan J


    Attending professional continuing education (CE) is an important component of librarianship. This research study identified librarians' preferences in delivery modalities of instruction for professional CE. The study also identified influential factors associated with attending CE classes. Five instruction-delivery modalities and six influential factors were identified for inclusion in an online survey. The survey completed by members of the American Library Association (ALA), Special Libraries Association (SLA), and Medical Library Association (MLA) provided the data for analysis of librarian preferences and influential factors. The majority of respondents were MLA members, followed by ALA and SLA members. Librarians from all three library associations preferred the face-to-face instructional modality. The most influential factor associated with the decision to attend a professional CE class was cost. All five instruction-delivery modalities present useful structures for imparting professional CE. As librarians' experience with different modalities increases and as technology improves, preferences in instruction delivery may shift. But at present, face-to-face remains the most preferred modality. Based on the results of this study, cost was the most influential factor associated with attending a CE class. This may change as additional influential factors are identified and analyzed in future studies.

  10. Appearance-change instruction effects on eyewitness lineup identification accuracy are not moderated by amount of appearance change. (United States)

    Molinaro, Peter F; Arndorfer, Andrea; Charman, Steve D


    Instructing witnesses that a criminal may have changed appearance prior to showing them a lineup has been shown to increase false identifications without increasing correct identifications (S. D. Charman & G. L. Wells, 2007, Is the appearance-change instruction a good idea? Law and Human Behavior, Vol. 31, pp. 3-22). However, the generalizability of the effects of this appearance-change instruction (ACI) is unknown, and there are reasons to believe that the instruction's effects may be moderated by the amount of appearance change the criminal has actually undergone. The current study tested this hypothesis. Undergraduate students (N = 315) were exposed to a series of target faces and lineups, some of which contained the target and some of which did not, and made identification decisions. Half of the participants received a standard ACI prior to each lineup; the other half did not. The targets varied with respect to the amount to which their appearance had changed. Results indicated that the ACI inflated false identifications without inflating correct identifications, and that these effects did not depend on the amount of appearance change the target had undergone. Current recommendations to administer the ACI seem to be unfounded and may be harmful to the reliability of identification evidence. (c) 2013 APA, all rights reserved

  11. Educating Jurors about Forensic Evidence: Using an Expert Witness and Judicial Instructions to Mitigate the Impact of Invalid Forensic Science Testimony. (United States)

    Eastwood, Joseph; Caldwell, Jiana


    Invalid expert witness testimony that overstated the precision and accuracy of forensic science procedures has been highlighted as a common factor in many wrongful conviction cases. This study assessed the ability of an opposing expert witness and judicial instructions to mitigate the impact of invalid forensic science testimony. Participants (N = 155) acted as mock jurors in a sexual assault trial that contained both invalid forensic testimony regarding hair comparison evidence, and countering testimony from either a defense expert witness or judicial instructions. Results showed that the defense expert witness was successful in educating jurors regarding limitations in the initial expert's conclusions, leading to a greater number of not-guilty verdicts. The judicial instructions were shown to have no impact on verdict decisions. These findings suggest that providing opposing expert witnesses may be an effective safeguard against invalid forensic testimony in criminal trials. © 2015 American Academy of Forensic Sciences.

  12. Instructional Quality Features in Videotaped Biology Lessons: Content-Independent Description of Characteristics (United States)

    Dorfner, Tobias; Förtsch, Christian; Boone, William; Neuhaus, Birgit J.


    A number of studies on single instructional quality features have been reported for mathematics and science instruction. For summarizing single instructional quality features, researchers have created a model of three basic dimensions (classroom management, supportive climate, and cognitive activation) of instructional quality mainly through observing mathematics instruction. Considering this model as valid for all subjects and as usable for describing instruction, we used it in this study which aimed to analyze characteristics of instructional quality in biology lessons of high-achieving and low-achieving classes, independently of content. Therefore, we used the data of three different previous video studies of biology instruction conducted in Germany. From each video study, we selected three high-achieving and three low-achieving classes (N = 18 teachers; 35 videos) for our multiple-case study, in which conspicuous characteristics of instructional quality features were qualitatively identified and qualitatively analyzed. The amount of these characteristics was counted in a quantitative way in all the videos. The characteristics we found could be categorized using the model of three basic dimensions of instructional quality despite some subject-specific differences for biology instruction. Our results revealed that many more characteristics were observable in high-achieving classes than in low-achieving classes. Thus, we believe that this model could be used to describe biology instruction independently of the content. We also make the claims about the qualities for biology instruction—working with concentration in a content-structured environment, getting challenged in higher order thinking, and getting praised for performance—that could have positive influence on students' achievement.

    Full Text Available The main goal of this study was to analyze whether primary teachers use evidence-based reading instruction for primary-grade readers. The study sample consisted of six teachers whose teaching was recorded. The observation instrument used was developed ad hoc for this study. The recording instrument used was Match Vision Studio. The data analysis was performed using SAS, GT version 2.0 E, and THEME. The results indicated that the teaching practices used most frequently and for the longest duration were: feedback (i.e., correcting the student when reading; fluency (i.e., individual and group reading, both out loud and silently, with and without intonation; literal or inference comprehension exercises (i.e., summarizing, asking questions; and use of educational resources (i.e., stories, songs, poems. Later, we conducted analyses of T-Patterns that showed the sequence of instruction in detail. We can conclude that <50% of the teaching practices used by the majority of teachers were based on the recommendations of the National Reading Panel (NRP. Only one teacher followed best practices. The same was the case for instructional time spent on the five essential components of reading, with the exception of teacher E., who dedicated 70.31% of class time implementing best practices. Teaching practices (i.e., learners' activities designed and implemented to exercise and master alphabetic knowledge and phonological awareness skills were used less frequently in the classroom.

  15. Word Decoding Development during Phonics Instruction in Children at Risk for Dyslexia. (United States)

    Schaars, Moniek M H; Segers, Eliane; Verhoeven, Ludo


    In the present study, we examined the early word decoding development of 73 children at genetic risk of dyslexia and 73 matched controls. We conducted monthly curriculum-embedded word decoding measures during the first 5 months of phonics-based reading instruction followed by standardized word decoding measures halfway and by the end of first grade. In kindergarten, vocabulary, phonological awareness, lexical retrieval, and verbal and visual short-term memory were assessed. The results showed that the children at risk were less skilled in phonemic awareness in kindergarten. During the first 5 months of reading instruction, children at risk were less efficient in word decoding and the discrepancy increased over the months. In subsequent months, the discrepancy prevailed for simple words but increased for more complex words. Phonemic awareness and lexical retrieval predicted the reading development in children at risk and controls to the same extent. It is concluded that children at risk are behind their typical peers in word decoding development starting from the very beginning. Furthermore, it is concluded that the disadvantage increased during phonics instruction and that the same predictors underlie the development of word decoding in the two groups of children.

  16. Political Bildung in the Context of Discipline, Instruction, and Moral Guidance

    Directory of Open Access Journals (Sweden)

    Thomas Rucker


    Full Text Available Johann Friedrich Herbart (1776-1841 is considered the founding father of the science of education. In this article, I will try to show that Herbart sees the promotion of political Bildung as the task of discipline, instruction, and moral guidance, and that his work presents important components of a theory of political Bildung within an educational setting. According to Herbart, the political relationship to self and the world relates to issues that not only affect the lives of some but of a majority of people. But it is not people’s collective life as such that is the point of orientation for the political relationship to self and the world, but only the collective life where problems have arisen. According to Herbart, politics results from a conflict about the question as to how to regulate people’s collective life. While discipline, by providing the basic preconditions for instruction and moral guidance, makes merely an indirect contribution to political Bildung, the two latter forms of education – instruction and moral guidance – serve as the actual means by which political Bildung is achieved.

    Full Text Available Zoltán Dörnyei (2005 proposed a new form of motivation which is aiming at equipping the learners with a lifelong approach to motivation which is self-induced by the learner and it is not needed for any extrinsic mediation, having understood how to keep yourself motivated. This study was an attempt to find out the effect of self-motivation strategies instruction on the learners belief on learner autonomy in L2 learning. To find out the possible effect of our independent variable we selected one intermediate level class in grade 2 (25 male in high school out of the whole population of high school students in west Azerbaijan, Iran via availability sampling. Having ensured for the homogeneity of the class members’ English proficiency through Nelson test, we gave them a questionnaire on the learner’s belief on autonomy in learning L2 to answer. Then within two months, in a separate class the students were given instructions on how to employ self-motivation strategies while learning English. After two months of instruction, they were given the same questionnaire again to get to know the possible effect of our independent variable. Having analyzed the obtained data in SPSS software, the results showed that our hypothesis was rejected and our null hypothesis was verified.

  20. Better together: Simultaneous presentation of speech and gesture in math instruction supports generalization and retention. (United States)

    Congdon, Eliza L; Novack, Miriam A; Brooks, Neon; Hemani-Lopez, Naureen; O'Keefe, Lucy; Goldin-Meadow, Susan


    When teachers gesture during instruction, children retain and generalize what they are taught (Goldin-Meadow, 2014). But why does gesture have such a powerful effect on learning? Previous research shows that children learn most from a math lesson when teachers present one problem-solving strategy in speech while simultaneously presenting a different, but complementary, strategy in gesture (Singer & Goldin-Meadow, 2005). One possibility is that gesture is powerful in this context because it presents information simultaneously with speech. Alternatively, gesture may be effective simply because it involves the body, in which case the timing of information presented in speech and gesture may be less important for learning. Here we find evidence for the importance of simultaneity: 3 rd grade children retain and generalize what they learn from a math lesson better when given instruction containing simultaneous speech and gesture than when given instruction containing sequential speech and gesture. Interpreting these results in the context of theories of multimodal learning, we find that gesture capitalizes on its synchrony with speech to promote learning that lasts and can be generalized.

    Full Text Available The Language teaching is a complex process influenced by many psychological factors such as personality traits (Tonelson, 1981 and socio-communicative styles (Thomas. Et al. 1994. This research sets out to investigate the effect of Teachers' Introvert and Extrovert personality on their instructional Immediacy. In order to address this issue, a study was conducted on 14 PhD holder university EFL lecturers from Guilan province. Instruments for this research included preliminary Myers-Briggs Personality Type Indicator (MBTI Test, non-verbal immediacy scale, along with verbal immediacy scale observation inventory. After determining the lecturers' Introvert/Extrovert personality, at the next stage, six sessions of direct observation of each lecturer's classroom instructional immediacy were conducted. Statistical analysis of Fisher's exact test between data along with Pearson's correlation was run to determine the relationship between teacher's extrovert personality and their use of verbal immediacy; the results indicate strong, positive correlation (r=.7, p<. 03. Similarly, a strong, positive correlation was found between extrovert personality and use of non-verbal immediacy (r=.75, p<. 01. The other finding of the study was that instructors’ gender showed no significant relation with their verbal and nonverbal instructional immediacy.

  2. A Hundred Years of Physics on Show

    CERN Multimedia


    The New Yorker Richard Feynman, well known to all physicists for his diagrams. Eleven vivid posters have recently been hung along the Theoretical Physics corridor on the first floor of Building 53. They tell the story of a century of physics, between 1900 and the end of the nineteen-nineties, the century that gave us atomic and quantum physics and the great breakthroughs that have rocked our understanding of the world and the universe. The posters are a gift from the American Physical Society to the CERN Library. As they were designed for high school and university book collections in the US, they necessarily have a somewhat American view of the history of science. But it is still instructive to revisit contemporary physics through its great figures, such as Marie Curie, Stephen Hawking, and Richard Feynman, not to mention Albert Einstein and many others. Why not take the time for a little trip down this particular stretch of Memory Lane?

  4. Brief, cooperative peer-instruction sessions during lectures enhance student recall and comprehension* (United States)

    Zhang, Niu; Henderson, Charles N.R.


    Objective: The objective of this study was to evaluate the academic impact of cooperative peer instruction during lecture pauses in an immunology/endocrinology course. Methods: Third-quarter students participated across iterations of the course. Each class offered 20 lectures of 50 minutes each. Classes were divided into a peer-instruction group incorporating cooperative peer instruction and a control group receiving traditional lectures. Peer-instruction group lectures were divided into 2–3 short presentations followed by a multiple-choice question (MCQ). Students recorded an initial answer and then had 1 minute to discuss answers with group peers. Following this, students could submit a revised answer. The control group received the same lecture material, but without MCQs or peer discussions. Final-exam scores were compared across study groups. A mixed-design analysis of covariance was used to analyze the data. Results: There was a statistically significant main effect for the peer-instruction activity (F(1, 93) = 6.573, p = .012, r = .257), with recall scores higher for MCQs asked after peer-instruction activities than for those asked before peer instruction. Final-exam scores at the end of term were greater in the peer-instruction group than the control group (F(1, 193) = 9.264, p = .003, r = .214; question type, F(1, 193) = 26.671, p = .000, r = .348). Conclusion: Lectures with peer-instruction pauses increase student recall and comprehension compared with traditional lectures. PMID:26967766

    Full Text Available A key shift of thinking for effective learning and teaching of listening input has been seen and organized in education locally and globally. This study has probed whether metacognitive instruction through a pedagogical cycle shifts high-intermediate students' English language learning and English as a second language (ESL teacher's teaching focus on listening input. Twenty male Iranian students with an age range of 18 to 24 received a guided methodology including metacognitive strategies (planning, monitoring, and evaluation for a period of three months. This study has used the strategies and probed the importance of metacognitive instruction through interviewing both the teacher and the students. The results have shown that metacognitive instruction helped both the ESL teacher's and the students' shift of thinking about teaching and learning listening input. This key shift of thinking has implications globally and locally for classroom practices of listening input.

  6. Understanding the variable effect of instructional innovations on student learning (United States)

    Iverson, Heidi L.


    As a result of dissatisfaction with the traditional lecture-based model of education a large number of reform-oriented instructional innovations have been developed, enacted, and studied in undergraduate physics courses. While previous work has shown that the impact of instructional innovations on student learning has been overwhelmingly positive, it has also been highly variable. The purpose of this analysis is to investigate this variability. For this analysis, 79 published studies on undergraduate physics instructional innovations were analyzed with respect to the types of innovations used and the methodological characteristics of the studies themselves. The findings of this analysis have indicated that nearly half of the variability in effect size can be accounted for by study design characteristics rather than by the characteristics of the innovations used. However, a subsequent analysis illustrated that one specific innovation, Workshop/Studio Physics, appears to be particularly effective within the observed sample of studies.

  7. Using Technology-Nested Instructional Strategies to Enhance Student Learning

    Directory of Open Access Journals (Sweden)

    Angela Lumpkin, PhD


    Full Text Available Students today expect the use of technology in their classes, rather than have to listen to less-than-engaging lectures. College students are connected electronically and incessant technology consumers. As a result, they may prefer the infusion of technologies to help them learn and enjoy the process of learning, rather than having to listen exclusively to lectures. To investigate this, the authors solicited student perceptions to assess the importance of learning through technology-nested instructional strategies. Student perceptions give direction to and affirm the benefits of instructional strategies that increase student motivation to engage more actively in their learning. Based on quantitative and qualitative responses through action research in multiple courses, students perceive their learning as more engaging and enjoyable when technology-nested instructional strategies are infused into their classes.

  8. The role of translation in undergraduate medical English instruction

    Directory of Open Access Journals (Sweden)

    Sofija Micic


    Full Text Available For most of its history of undergraduate medical English instruction at Belgrade University, translation was a major part of teaching and assessment. Educational reforms in the early 21st century resulted in a shift towards content-based instruction with the focus on reading comprehension and less translation. The paper analyses the new role of translation in the reformed Serbian curriculum. A brief history of Medical English instruction is outlined. The role of lexicon and the level of discourse within the teaching of English translation in the Serbian curriculum are explored. Some suggestions for the improvement of medical English translation in the Serbian curriculum are offered. It has been shown that translation is a valuable skill to be mastered. Translation exercises allow instructors to recognize language-related comprehension problems. Furthermore, teaching translation is important in that future medical professionals are able to recognize different medical genres and structural differences between English and Serbian.

    Full Text Available Objective – The objective of this study was twofold: 1 to assess the effectiveness of curriculum changes made from the 2009 freshman English library instruction curriculum to the 2010 curriculum at Loyola Marymount University (LMU; and 2 to evaluate the effectiveness of library instruction delivered via a “blended” combination of face-to-face and online instruction versus online instruction alone.Methods – An experimental design compared random samples of student scores from 2009 and 2010 worksheets to determine the effects of a new curriculum on student learning. A second experiment examined the effect of delivery method on student learning by comparing scores from a group of students receiving only online instruction against a group receiving blended instruction.Results – The first component of the study, which compared scores between 2009 and 2010 to examine the effects of the curriculum revisions, had mixed results. Students scored a significantly higher mean in 2010 on completing and correctly listing book citation components than in 2009, but a significantly lower mean on constructing a research question. There was a significant difference in the distribution of scores for understanding differences between information found on the Internet versus through the Library that was better in 2010 than 2009, but worse for narrowing a broad research topic. For the study that examined computer aided instruction, the group of students receiving only computer-assisted instruction did significantly better overall than the group receiving blended instruction. When separate tests were run for each skill, two particular skills, generating keywords and completing book citation and location elements, resulted in a significantly higher mean.Conclusions – The comparison of scores between 2009 and 2010 were mixed, but the evaluation process helped us identify continued problems in the teaching materials to address in the next cycle of revisions

    The aim of this study was to investigate the impact of three instructional styles (traditional teaching, problem-based instruction, and teaching by demonstration) of teaching physics on students' attitudes and achievement. The sample consisted of 106 Saudi students in three physics classes in the second semester of the academic year 1998--1999. Three instruments were used in collecting the data for both quantitative and qualitative parts of the study. For the quantitative part, the researcher developed and pilot tested a 35-item questionnaire with versions to measure students' attitudes before the start of the experiment and then to measure students' attitudes toward the method of teaching. In addition, the researcher developed a 12-item achievement test to measure students gain scores which was administered at the beginning and the end of the treatment. For the qualitative part, the researcher constructed an interview guide consisting of five-open ended questions. The questions were geared to discover students' attitudes toward the implemented instructional style, and if this instructional style assisted them to acquire a good understanding of the studied unit. In the quantitative part, the results showed a significant correlation between students' attitudes toward the method of teaching and their achievement on the posttests. Furthermore, the findings from the one-way ANOVA indicated that there was a significant difference among the three groups in terms of achievement. The mean of achievement gain scores was highest for the problem-based group, followed by the group that was taught by demonstration, and then the traditional teaching group. The findings from the ANOVA indicated that there was also no significant difference between the three groups in terms of attitudes. In the qualitative part, the answers of the five questions revealed four themes: attitudes toward the method of teaching, reasons for liking or disliking the method of teaching, methods of

  4. An instructional intervention to encourage effective deep collaborative learning in undergraduate veterinary students. (United States)

    Khosa, Deep K; Volet, Simone E; Bolton, John R


    In recent years, veterinary education has received an increased amount of attention directed at the value and application of collaborative case-based learning. The benefit of instilling deep learning practices in undergraduate veterinary students has also emerged as a powerful tool in encouraging continued professional education. However, research into the design and application of instructional strategies to encourage deep, collaborative case-based learning in veterinary undergraduates has been limited. This study focused on delivering an instructional intervention (via a 20-minute presentation and student handout) to foster productive, collaborative case-based learning in veterinary education. The aim was to instigate and encourage deep learning practices in a collaborative case-based assignment and to assess the impact of the intervention on students' group learning. Two cohorts of veterinary students were involved in the study. One cohort was exposed to an instructional intervention, and the other provided the control for the study. The instructional strategy was grounded in the collaborative learning literature and prior empirical studies with veterinary students. Results showed that the intervention cohort spent proportionally more time on understanding case content material than did the control cohort and rated their face-to-face discussions as more useful in achieving their learning outcomes than did their control counterparts. In addition, the perceived difficulty of the assignment evolved differently for the control and intervention students from start to end of the assignment. This study provides encouraging evidence that veterinary students can change and enhance the way they interact in a group setting to effectively engage in collaborative learning practices.

  5. Predictors of job satisfaction among Academic Faculty: Do instructional and clinical faculty differ? (United States)

    Chung, Kevin C.; Song, Jae W.; Kim, H. Myra; Woolliscroft, James O.; Quint, Elisabeth H.; Lukacs, Nicholas W.; Gyetko, Margaret R.


    Objectives To identify and compare predictors of job satisfaction between the instructional and clinical faculty tracks. Method A 61-item faculty job satisfaction survey was distributed to 1,898 academic faculty at the University of Michigan Medical School. The anonymous survey was web-based. Questions covered topics on departmental organization, research, clinical and teaching support, compensation, mentorship, and promotion. Levels of satisfaction were contrasted between the two tracks, and predictors of job satisfaction were identified using linear regression models. Results The response rates for the instructional and clinical tracks were 43.1% and 41.3%, respectively. Clinical faculty reported being less satisfied with how they are mentored, and fewer reported understanding the process for promotion. There was no significant difference in overall job satisfaction between faculty tracks. Surprisingly, clinical faculty with mentors were significantly less satisfied with how they were being mentored, with career advancement and overall job satisfaction, compared to instructional faculty mentees. Additionally, senior-level clinical faculty were significantly less satisfied with their opportunities to mentor junior faculty compared to senior-level instructional faculty. Significant predictors of job satisfaction for both tracks included areas of autonomy, meeting career expectations, work-life balance, and departmental leadership. Unique to the clinical track, compensation and career advancement variables also emerged as significant predictors. Conclusion Greater effort must be placed in the continued attention to faculty well-being both at the institutional level and at the level of departmental leadership. Success in enhancing job satisfaction is more likely if directed by locally designed assessments involving department chairs, specifically in fostering more effective mentoring relationships focused on making available career advancement activities such as

    Full Text Available Abstract Background Teaching of motor skills is fundamental to physical therapy practice. In order to optimize the benefits of these teaching and training efforts, various forms of patient education material are developed and handed out to patients. One very important fact has been overlooked. While comparative effectiveness of various modes of instruction has been studied in adults, attention has not been paid to the fact that learning capabilities of children are different from that of adults. The intent of the present study is to compare the effectiveness of video and handout mode of instructions specifically on children. Methods A total of 115 normal elementary-age children aged 10 to 12 years of age were studied. The children were randomized into two groups: A the video group, and B the handout group. The video group viewed the video for physical therapy exercises while the handout group was provided with paper handouts especially designed according to the readability of their age group. Results Statistical analysis using the student's't' test showed that subjects of both the video and handout groups exhibited equal overall performance accuracy. There was no significant difference between the groups both in acquisition and retention accuracy tests. Conclusion The findings of the present study suggest that if the readability and instructional principles applicable to different target age groups are strictly adhered to, then both video as well as handout modes of instructions result in similar feedback and memory recall in ten to twelve year-old children. Principles of readability related to the patient age are of utmost importance when designing the patient education material. These findings suggest that the less expensive handouts can be an effective instructional aid for teaching exercises to children with various neuromuscular, rheumatic, and orthopedics conditions and the most costly videotape techniques are not necessarily better.

  2. Learning from Narrated Instruction Videos. (United States)

    Alayrac, Jean-Baptiste; Bojanowski, Piotr; Agrawal, Nishant; Sivic, Josef; Laptev, Ivan; Lacoste-Julien, Simon


    Automatic assistants could guide a person or a robot in performing new tasks, such as changing a car tire or repotting a plant. Creating such assistants, however, is non-trivial and requires understanding of visual and verbal content of a video. Towards this goal, we here address the problem of automatically learning the main steps of a task from a set of narrated instruction videos. We develop a new unsupervised learning approach that takes advantage of the complementary nature of the input video and the associated narration. The method sequentially clusters textual and visual representations of a task, where the two clustering problems are linked by joint constraints to obtain a single coherent sequence of steps in both modalities. To evaluate our method, we collect and annotate a new challenging dataset of real-world instruction videos from the Internet. The dataset contains videos for five different tasks with complex interactions between people and objects, captured in a variety of indoor and outdoor settings. We experimentally demonstrate that the proposed method can automatically discover, learn and localize the main steps of a task input videos.

  3. Teacher change in beliefs and practices in science and literacy instruction with English language learners (United States)

    Lee, Okhee


    This study examined patterns of change in beliefs and practices as elementary teachers learned to establish instructional congruence, a process of mediating academic disciplines with linguistic and cultural experiences of diverse student groups. The study focused on six bilingual Hispanic teachers working with fourth-grade, mostly Hispanic students. The results indicated that teacher learning and change occurred in different ways in the areas of science instruction, students' language and culture, English language and literacy instruction, and integration of these areas in establishing instructional congruence. The results also indicated that establishing instructional congruence was a gradual and demanding process requiring teacher reflection and insight, formal training, and extensive support and sharing. Implications for further research in promoting achievement for all students are discussed.

  4. The Effect of Performance-Contingent Incentives when Task Complexity is Manipulated through Instruction

    Directory of Open Access Journals (Sweden)

    Monte Wynder


    Full Text Available When, and how, performance-contingent incentives improve performance is an important question fororganisations. Empirical results have been mixed – performance-contingent incentives sometimes increaseperformance, sometimes decrease performance, and sometimes have no effect. Theorists have called forfurther research to identify the effect of various moderating variables, including knowledge and taskcomplexity. This study responds by considering the role of instruction in providing the necessary knowledgeto reduce task complexity. The results suggest that a performance-contingent penalty can be a particularlyeffective means of directing effort for a simple task. For a complex task, performance can be improvedthrough instruction. The type of instruction is important – with rule-based instruction effectively directingeffort – however principle-based instruction is necessary to facilitate problem investigation and problemsolving.

  5. Revisiting cognitive and learning styles in computer-assisted instruction: not so useful after all. (United States)

    Cook, David A


    In a previous systematic review, the author proposed that adaptation to learners' cognitive and learning styles (CLSs) could improve the efficiency of computer-assisted instruction (CAI). In the present article, he questions that proposition, arguing that CLSs do not make a substantive difference in CAI. To support this argument, the author performed an updated systematic literature search, pooled new findings with those from the previous review, and reinterpreted this evidence with a focus on aptitude-treatment interactions. (An aptitude-treatment interaction occurs when a student with attribute 1 learns better with instructional approach A than with approach B, whereas a student with attribute 2 learns better with instructional approach B).Of 65 analyses reported in 48 studies, only 9 analyses (14%) showed significant interactions between CLS and instructional approach. It seems that aptitude-treatment interactions with CLSs are at best infrequent and small in magnitude. There are several possible explanations for this lack of effect. First, the influence of strong instructional methods likely dominates the impact of CLSs. Second, current methods for assessing CLSs lack validity evidence and are inadequate to accurately characterize the individual learner. Third, theories are vague, and empiric evidence is virtually nonexistent to guide the planning of style-targeted instructional designs. Adaptation to learners' CLSs thus seems unlikely to enhance CAI. The author recommends that educators focus on employing strong instructional methods. Educators might also consider assessing and adapting to learners' prior knowledge or allowing learners to select among alternate instructional approaches.

  7. The Effect of Multiple Intelligence-Based Instruction on Critical Thinking of Full Day Islamic Elementary Schools Students

    Directory of Open Access Journals (Sweden)

    Alhamuddin Alhamuddin


    Full Text Available Lack of critical thinking skills of elementary schools’ students was influenced by teachers’ domination in instructional activities; meanwhile students did not play independently as the learners. Theoretically, multiple intelligences based instruction is an appropriate solution. For that reason, this research aims to know the impact of multiple intelligences based instruction on students' critical thinking skills. The research was conducted at Al-Amanah and Buahati Islamic Elementary Schools by using a quantitative approach with case study method. Data collected through critical thinking tests was analyzed by using independent sample t-test to examine the impact of instruction on students' critical thinking skills. The results showed that the implementation of multiple intelligences based intruction had significant effect on students’ critical thinking skills. From the finding, some recommendations are given as follows: 1 The teacher’s role is not only for transferring knowledge based on his/her competencies but also students’ characteristics reflecting their instruction styles; and 2 for further researcher, it is suggested to investigate this issues more specifically and comprehensively.   Kurangnya keterampilan berpikir kritis dari siswa sekolah dasar dipengaruhi oleh dominasi guru dalam kegiatan pembelajaran; Sementara itu siswa tidak bermain secara independen sebagai peserta didik.

  8. Effects of socioscientific issues-based instruction on argumentation ability and biology concepts of upper secondary school students (United States)

    Faelt, Surasak; Samiphak, Sara; Pattaradilokrat, Sittiporn


    Argumentation skill is an essential skill needed in students, and one of the competencies in scientific literacy. Through arguing on socioscientific issues, students may gain deeper conceptual understanding. The purpose of this research is to examine the efficacy of a socioscientific issues-based instruction compared with an inquirybased instruction. This is to determine which one is better in promoting 10th grade students' argumentation ability and biology concepts of digestive system and cellular respiration. The forty 10th grade students included in this study were from two mathematics-science program classes in a medium-sized secondary school located in a suburb of Buriram province, Thailand. The research utilizes a quasi-experimental design; pre-test post-test control group design. We developed and implemented 4 lesson plans for both socioscientific issues-based instruction and inquiry-based instruction. Ten weeks were used to collect the data. A paper-based questionnaire and informal interviews were designed to test students' argumentation ability, and the two-tier multiple-choice test was designed to test their biology concepts. This research explore qualitatively and quantitatively students' argumentation abilities and biology concepts, using arithmetic mean, mean of percentage, standard deviation and t-test. Results show that there is no significant difference between the two group regarding mean scores of the argumentation ability. However, there is significant difference between the two groups regarding mean scores of the biology concepts. This suggests that socioscientific issues-based instruction could be used to improve students' biology concepts.

  9. Pre-Service Teachers: An Analysis of Reading Instruction in High Needs Districts Dual Language Classrooms

    Directory of Open Access Journals (Sweden)

    Michael Whitacre


    Full Text Available Pre-service teachers need opportunities to apply theory and connect to best practices as they teach in classroom settings be it, whole or small group. For many pre-service teachers often times their experience is limited to simply watching instruction or working with small groups of students (Pryor & Kuhn, 2004. The student teaching experience is a critical component of the teacher preparation program. Through the use of the English Language Learner Classroom Observation Instrument (ELLCOI, and researcher observation the hope is that these will aid in bringing to light the instructional activities used by pre-service teachers during reading instruction with ELLs. This study explores how pre-service bilingual teachers connect theory into practice by examining their instruction in the following categories: Instructional Practices, Interactive Teaching, English-Language Development, and Content Specific to Reading as listed in The English Language Learner Classroom Observation Instrument (ELLCOI developed by Haager, Gersten, Baker, and Graves (2003. To capture these instructional events video tape recordings of eight South Texas pre-service teachers were taken during a reading language arts lesson in order to observe instruction in high need districts’ dual language/bilingual classrooms. Data were compiled to capture the nature and quality of instruction on key essential elements, as well as reading instructional practices specific to the teaching/learning process in the dual language classroom. The findings portray the results of the ELLCOI with bilingual/ESL pre- service teachers and how they make sense of their instructional practices as a means to instruction in one-way dual language public school classrooms.

  11. Instructable autonomous agents. Ph.D. Thesis (United States)

    Huffman, Scott Bradley


    In contrast to current intelligent systems, which must be laboriously programmed for each task they are meant to perform, instructable agents can be taught new tasks and associated knowledge. This thesis presents a general theory of learning from tutorial instruction and its use to produce an instructable agent. Tutorial instruction is a particularly powerful form of instruction, because it allows the instructor to communicate whatever kind of knowledge a student needs at whatever point it is needed. To exploit this broad flexibility, however, a tutorable agent must support a full range of interaction with its instructor to learn a full range of knowledge. Thus, unlike most machine learning tasks, which target deep learning of a single kind of knowledge from a single kind of input, tutorability requires a breadth of learning from a broad range of instructional interactions. The theory of learning from tutorial instruction presented here has two parts. First, a computational model of an intelligent agent, the problem space computational model, indicates the types of knowledge that determine an agent's performance, and thus, that should be acquirable via instruction. Second, a learning technique, called situated explanation specifies how the agent learns general knowledge from instruction. The theory is embodied by an implemented agent, Instructo-Soar, built within the Soar architecture. Instructo-Soar is able to learn hierarchies of completely new tasks, to extend task knowledge to apply in new situations, and in fact to acquire every type of knowledge it uses during task performance - control knowledge, knowledge of operators' effects, state inferences, etc. - from interactive natural language instructions. This variety of learning occurs by applying the situated explanation technique to a variety of instructional interactions involving a variety of types of instructions (commands, statements, conditionals, etc.). By taking seriously the requirements of flexible

  13. Instructional changes based on cogenerative physics reform (United States)

    Samuels, Natan; Brewe, Eric; Kramer, Laird


    We describe changes in a physics teacher's pedagogy and cultural awareness that resulted from her students' involvement in reforming their classroom. For this case study, we examined a veteran high school teacher's semester-long use of CMPLE (the Cogenerative Mediation Process for Learning Environments) in her Modeling Instruction classroom. CMPLE is a formative intervention designed to help students and instructors collaborate to change classroom dynamics, based on how closely the environment matches their learning preferences. Analysis of classroom videos, interviews, and other artifacts indicates that adapting the environment to align with the preferences of that shared culture affected the instructor in complex ways. We will trace her teaching practices and her self-described awareness of the culture of learning, to highlight notable changes. The teacher espoused deeper understanding of her students' physics learning experience, which she gained from including students in responding to their own individual and collective learning preferences.

  15. Teacher spatial skills are linked to differences in geometry instruction. (United States)

    Otumfuor, Beryl Ann; Carr, Martha


    Spatial skills have been linked to better performance in mathematics. The purpose of this study was to examine the relationship between teacher spatial skills and their instruction, including teacher content and pedagogical knowledge, use of pictorial representations, and use of gestures during geometry instruction. Fifty-six middle school teachers participated in the study. The teachers were administered spatial measures of mental rotations and spatial visualization. Next, a single geometry class was videotaped. Correlational analyses revealed that spatial skills significantly correlate with teacher's use of representational gestures and content and pedagogical knowledge during instruction of geometry. Spatial skills did not independently correlate with the use of pointing gestures or the use of pictorial representations. However, an interaction term between spatial skills and content and pedagogical knowledge did correlate significantly with the use of pictorial representations. Teacher experience as measured by the number of years of teaching and highest degree did not appear to affect the relationships among the variables with the exception of the relationship between spatial skills and teacher content and pedagogical knowledge. Teachers with better spatial skills are also likely to use representational gestures and to show better content and pedagogical knowledge during instruction. Spatial skills predict pictorial representation use only as a function of content and pedagogical knowledge. © 2017 The British Psychological Society.

  16. An impoverished machine: challenges to human learning and instructional technology. (United States)

    Taraban, Roman


    Many of the limitations to human learning and processing identified by cognitive psychologists over the last 50 years still hold true, including computational constraints, low learning rates, and unreliable processing. Instructional technology can be used in classrooms and in other learning contexts to address these limitations to learning. However, creating technological innovations is not enough. As part of psychological science, the development and assessment of instructional systems should be guided by theories and practices within the discipline. The technology we develop should become an object of research like other phenomena that are studied. In the present article, I present an informal account of my own work in assessing instructional technology for engineering thermodynamics to show not only the benefits, but also the limitations, in studying the technology we create. I conclude by considering several ways of advancing the development of instructional technology within the SCiP community, including interdisciplinary research and envisioning learning contexts that differ radically from traditional learning focused on lectures and testing.

  17. Single instruction computer architecture and its application in image processing (United States)

    Laplante, Phillip A.


    A single processing computer system using only half-adder circuits is described. In addition, it is shown that only a single hard-wired instruction is needed in the control unit to obtain a complete instruction set for this general purpose computer. Such a system has several advantages. First it is intrinsically a RISC machine--in fact the 'ultimate RISC' machine. Second, because only a single type of logic element is employed the entire computer system can be easily realized on a single, highly integrated chip. Finally, due to the homogeneous nature of the computer's logic elements, the computer has possible implementations as an optical or chemical machine. This in turn suggests possible paradigms for neural computing and artificial intelligence. After showing how we can implement a full-adder, min, max and other operations using the half-adder, we use an array of such full-adders to implement the dilation operation for two black and white images. Next we implement the erosion operation of two black and white images using a relative complement function and the properties of erosion and dilation. This approach was inspired by papers by van der Poel in which a single instruction is used to furnish a complete set of general purpose instructions and by Bohm- Jacopini where it is shown that any problem can be solved using a Turing machine with one entry and one exit.

  19. Myopes show increased susceptibility to nearwork aftereffects. (United States)

    Ciuffreda, K J; Wallis, D M


    Some aspects of accommodation may be slightly abnormal (or different) in myopes, compared with accommodation in emmetropes and hyperopes. For example, the initial magnitude of accommodative adaptation in the dark after nearwork is greatest in myopes. However, the critical test is to assess this initial accommodative aftereffect and its subsequent decay in the light under more natural viewing conditions with blur-related visual feedback present, if a possible link between this phenomenon and clinical myopia is to be considered. Subjects consisted of adult late- (n = 11) and early-onset (n = 13) myopes, emmetropes (n = 11), and hyperopes (n = 9). The distance-refractive state was assessed objectively using an autorefractor immediately before and after a 10-minute binocular near task at 20 cm (5 diopters [D]). Group results showed that myopes were most susceptible to the nearwork aftereffect. It averaged 0.35 D in initial magnitude, with considerably faster posttask decay to baseline in the early-onset (35 seconds) versus late-onset (63 seconds) myopes. There was no myopic aftereffect in the remaining two refractive groups. The myopes showed particularly striking accommodatively related nearwork aftereffect susceptibility. As has been speculated and found by many others, transient pseudomyopia may cause or be a precursor to permanent myopia or myopic progression. Time-integrated increased retinal defocus causing axial elongation is proposed as a possible mechanism.

  20. Information literacy instruction in special libraries: the situation in the year 2010 in comparison with the year 2002

    Directory of Open Access Journals (Sweden)

    Uršula Tarfila


    Full Text Available Purpose: The aim of the research was to explore if information literacy instruction of Slovenian special library users has been improved since the last study in the year 2002,and if so, in which directions.Methodology/approach: Web-based survey was used to collect data from special libraries;the results were then compared with the findings of the survey carried out in 2002.Results: The results show that information literacy instruction of special library users has remained more or less unchanged. In the 2010 survey included special librarians are aware of the importance of developing information literacy but they are restricted by work overload, lack of resources and time, or are unskilled to perform this activity.As compared to the year 2002, a noticeable change has been observed only in the higher level of co-operation between special libraries and departments of their parent organizations.Research limitation: The sample size of both studies was not even, for advanced understanding of some results additional research methods should be used.Originality/practical implications: The study should stimulate special libraries to make a step forward in developing user instruction. However, information literacy is a core skill of the active working population and the driving force of innovation and competitiveness of the parent organization.

  1. The implementation and evaluation of teacher training in gaming instruction for secondary science: An action research project (United States)

    Sanders, Veronica

    This study implemented and evaluated gaming instruction as a professional development for science teachers at a Georgia high school. It was guided by four research questions that (a) assessed the impact of training in gaming instruction and evaluation of that training on science teachers' ability to use games; (b) examined evidence showing that science teachers used games; (c) assessed the impact of the implementation and subsequent evaluation of games-based training on how science teachers instruct their students; and (d) explored the use of change management principles to help teachers transition from traditional to gaming instruction. The study included a purposive sampling of 10 volunteer science teachers who received the professional development of training in gaming instruction and were observed as they used games to instruct their students. Quantitative data were collected from interviews, observations, and reviews of student assignments and teacher plans, and were statistically analyzed to answer the research questions. These same methods were used to obtain qualitative data, which were also analyzed to answer the research questions as well as to understand the meaning, beliefs and experience behind the numbers. Ultimately, data analysis revealed that the science teachers not only used gaming instruction but also that the training helped them to use gaming instruction and that they considered gaming instruction a viable instruction methodology. Finally, data analysis revealed that change management was successfully used in the study.
