Sample records for science proficiency scores

  1. High school science teacher perceptions of the science proficiency testing as mandated by the State of Ohio Board of Education

    Science.gov (United States)

    Jeffery, Samuel Shird

    There is a correlation between the socioeconomic status of secondary schools and scores on the State of Ohio's mandated secondary science proficiency tests. In low scoring schools many reasons effectively explain the low test scores as a result of the low socioeconomics. For example, one reason may be that many students are working late hours after school to help with family finances; parents may simply be too busy providing family income to realize the consequences of the testing program. There are many other personal issues students face that may cause them to score poorly an the test. The perceptions of their teachers regarding the science proficiency test program may be one significant factor. These teacher perceptions are the topic of this study. Two sample groups ware established for this study. One group was science teachers from secondary schools scoring 85% or higher on the 12th grade proficiency test in the academic year 1998--1999. The other group consisted of science teachers from secondary schools scoring 35% or less in the same academic year. Each group of teachers responded to a survey instrument that listed several items used to determine teachers' perceptions of the secondary science proficiency test. A significant difference in the teacher' perceptions existed between the two groups. Some of the ranked items on the form include teachers' opinions of: (1) Teaching to the tests; (2) School administrators' priority placed on improving average test scores; (3) Teacher incentive for improving average test scores; (4) Teacher teaching style change as a result of the testing mandate; (5) Teacher knowledge of State curriculum model; (6) Student stress as a result of the high-stakes test; (7) Test cultural bias; (8) The tests in general.

    2007-04-01

    Studies have found that Wechsler scale administration and scoring proficiency is not easily attained during graduate training. These findings may be related to methodological issues. Using a single-group repeated measures design, this study documents statistically significant, though modest, error reduction on the WAIS-III and WISC-III during a graduate course in assessment. The study design does not permit the isolation of training factors related to error reduction, or assessment of whether error reduction is a function of mere practice. However, the results do indicate that previous study findings of no or inconsistent improvement in scoring proficiency may have been the result of methodological factors. Implications for teaching individual intelligence testing and further research are discussed.

  6. Students' proficiency scores within multitrait item response theory

    2015-12-01

    In this paper we present a series of item response models of data collected using the Force Concept Inventory. The Force Concept Inventory (FCI) was designed to poll the Newtonian conception of force viewed as a multidimensional concept, that is, as a complex of distinguishable conceptual dimensions. Several previous studies have developed single-trait item response models of FCI data; however, we feel that multidimensional models are also appropriate given the explicitly multidimensional design of the inventory. The models employed in the research reported here vary in both the number of fitting parameters and the number of underlying latent traits assumed. We calculate several model information statistics to ensure adequate model fit and to determine which of the models provides the optimal balance of information and parsimony. Our analysis indicates that all item response models tested, from the single-trait Rasch model through to a model with ten latent traits, satisfy the standard requirements of fit. However, analysis of model information criteria indicates that the five-trait model is optimal. We note that an earlier factor analysis of the same FCI data also led to a five-factor model. Furthermore the factors in our previous study and the traits identified in the current work match each other well. The optimal five-trait model assigns proficiency scores to all respondents for each of the five traits. We construct a correlation matrix between the proficiencies in each of these traits. This correlation matrix shows strong correlations between some proficiencies, and strong anticorrelations between others. We present an interpretation of this correlation matrix.

  7. The English Proficiency Test of the Iranian Ministry of Science, Research, and Technology: A Review

    Full Text Available One of the serious decisions which every administrator may need to make during his/her professional career is to select or reject applicants based on their general language skills or competence. These significant decisions, which may be of serious consequences not only for the individuals but also for the society in general, are occasionally made based on norm-referenced proficiency tests. Out of internationally available proficiency tests such as the TOEFL test, those which fit the specific local cultural and academic contexts seem of greater prominence. One such test, which has been specifically designed for the Iranian EFL context by the Ministry of Science, Research, and Technology, is the MSRT proficiency test. While a few studies have been conducted on the analysis of the reliability and validity of the mentioned test, no study has yet reviewed the test and its component parts. Therefore, the current study aimed at considering the strengths and weaknesses of the test in general and its component items in particular. The results implicated that the MSRT benefits from more efficient general reliability and validity, well planned language items, practicality, ease of administration, objective scoring, ease of accessibility, as well as reasonable fees, while it needs to be more substantiated in terms of the inclusion of the speaking skill assessment, the computerized adaptive assessment procedures, and the correction factor for guessing. In addition, the use of the individual-based listening apparatus for testing listening comprehension as well as the consideration of the integrative communicative tests for its concurrent validity purposes can contribute to more appropriate distinction of proficient and non-proficient applicants.

    Abstract Integrated Science Education Outreach (InSciEd Out) is a collaboration formed between Mayo Clinic, Winona State University, and Rochester Public Schools (MN) with the shared vision of achieving excellence in science education. InSciEd Out employs an equitable partnership model between scientists, teachers, education researchers, and the community. Teams of teachers from all disciplines within a single school experience cutting-edge science using the zebrafish model system, as well as current pedagogical methods, during a summer internship at the Mayo Clinic. Within the internship, the teachers produce new curriculum that directly addresses opportunities for science education improvement at their own school. Zebrafish are introduced within the new curriculum to support a living model of the practice of science. Following partnership with the InSciEd Out program and 2 years of implementation in the classroom, teacher-interns from a K–8 public school reported access to local scientific technology and expertise they had not previously recognized. Teachers also reported improved integration of other disciplines into the scientific curriculum and a flow of concepts vertically from K through 8. Students more than doubled selection of an Honors science track in high school to nearly 90%. 98% of students who took the Minnesota Comprehensive Assessments in their 5th and 8th grade year (a span that includes 2 years of InSciEd Out) showed medium or high growth in science proficiency. These metrics indicate that cooperation between educators and scientists can result in positive change in student science proficiency and demonstrate that a higher expectation in science education can be achieved in US public schools.

    Continuous quality improvement (CQI) collaboration has not eliminated the morbidity variability seen among neonatal intensive care units (NICUs). Factors other than inconstant application of potentially better practices (PBPs) might explain divergent proficiency. Measure a composite morbidity score and determine whether cultural, environmental and cognitive factors distinguish high proficiency from lower proficiency NICUs. Retrospective analysis using a risk-adjusted composite morbidity score (Benefit Metric) and cultural survey focusing on very low birth weight (VLBW) infants from 39 NICUs, years 2000-2014. The Benefit Metric and yearly variance from the group mean was rank-ordered by NICU. A comprehensive survey was completed by each NICU exploring whether morbidity variance correlated with CQI methodology, cultural, environmental and/or cognitive characteristics. 58 272 VLBW infants were included, mean (SD) age 28.2 (3.0) weeks, birth weight 1031 (301) g. The 39 NICU groups' Benefit Metric improved 40%, from 80 in 2000 to 112 in 2014 (Pexpectations of providers, enhanced learning opportunities, knowledge of CQI fundamentals and more generous staffing. Cultural, environmental and cognitive characteristics vary among NICUs perhaps more than traditional CQI methodology and PBPs, possibly explaining the inconstancy of VLBW infant morbidity reduction efforts. High proficiency NICUs foster spirited team work and camaraderie, sustained learning opportunities and support of favourable staffing that allows problem solving and widespread involvement in CQI activities. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The study considers data from 2 UK-based proficiency schemes and includes data from a total of 29 rounds and 43 test materials over a period of 3 years. The results from the 2 schemes are similar and reinforce each other. The amplification process used in quantitative polymerase chain reaction determinations predicts a mixture of normal, binomial, and lognormal distributions dominated by the latter 2. As predicted, the study results consistently follow a positively skewed distribution. Log-transformation prior to calculating z-scores is effective in establishing near-symmetric distributions that are sufficiently close to normal to justify interpretation on the basis of the normal distribution.

    Full Text Available Percutaneous nephrolithotomy (PNL is a complicated procedure for urology trainees. This study was designed to investigate the effect of trainees’ ages and previous experience, as well as the number of operated cases, on proficiency at PNL by using patient outcomes. A cross sectional observational study was designed during a five-year period. Trainees in PNL fellowship programs were included. At the end of the program, the trainees’ performance in PNL was assessed regarding five competencies and scored 1-5. If the overall score was 4 or above, the trainee was considered as proficient. The trainees’ age at the beginning of the program and the years passed from their residency graduation were asked and recorded. Also, the number of PNL cases operated by each trainee was obtained via their logbooks. The age, years passed from graduation, and number of operated cases were compared between two groups of proficient and non-proficient trainees. Univariate and multivariate binary logistic regression analysis was applied to estimate the effect of aforementioned variables on the occurrence of the proficiency. Forty-two trainees were included in the study. The mean and standard deviation for the overall score were 3.40 (out of 5 and 0.67, respectively. Eleven trainees (26.2% recognized as proficient in performing PNL. Univariate regression analysis indicated that each of three variables (age, years passed from graduation and number of operated cases had statistically significant effect on proficiency. However, the multivariate regression analysis revealed that just the number of cases had significant effect on achieving proficiency. Although it might be assumed that trainees’ age negatively correlates with their scores, in fact, it is their amount of practice that makes a difference. A certain number of cases is required to be operated by a trainee in order to reach the desired competency in PNL.

    Computers and the Internet have the potential to enrich the lives of seniors and aid in the performance of important tasks required for independent living. A prerequisite for reaping these benefits is having the skills needed to use these systems, which is highly dependent on proper training. One prerequisite for efficient and effective training is being able to gauge current levels of proficiency. We developed a new measure (the Computer Proficiency Questionnaire, or CPQ) to measure computer proficiency in the domains of computer basics, printing, communication, Internet, calendaring software, and multimedia use. Our aim was to develop a measure appropriate for individuals with a wide range of proficiencies from noncomputer users to extremely skilled users. To assess the reliability and validity of the CPQ, a diverse sample of older adults, including 276 older adults with no or minimal computer experience, was recruited and asked to complete the CPQ. The CPQ demonstrated excellent reliability (Cronbach's α = .98), with subscale reliabilities ranging from .86 to .97. Age, computer use, and general technology use all predicted CPQ scores. Factor analysis revealed three main factors of proficiency related to Internet and e-mail use; communication and calendaring; and computer basics. Based on our findings, we also developed a short-form CPQ (CPQ-12) with similar properties but 21 fewer questions. The CPQ and CPQ-12 are useful tools to gauge computer proficiency for training and research purposes, even among low computer proficient older adults. © The Author 2013.

    2000-11-01

    The purpose of this study was to examine the effects of English language proficiency and levels of scientific reasoning skills of Hispanic English language learners and native English language speaking students on their acquisition of science content knowledge as measured by a state-wide standardized science test. The researcher studied a group of high school Hispanic English language learners and native English language speaking students participating in Grade 10 science classes. The language proficiency of the students was to be measured through the use of the Test of English as a Foreign Language (TOEFL) instrument. A Classroom Test of Scientific Reasoning developed by Lawson (1978) was administered in either English or Spanish to the group of Hispanic English language learners and in English to the group of native English language-speaking students in order to determine their levels of scientific reasoning skills. The students' acquisition of science content knowledge was measured through the use of statewide-standardized science test developed by the State's Department of Education. This study suggests that the levels of English language proficiency appear to influence the acquisition of science content knowledge of Hispanic English language learners in the study. The results of the study also suggest that with regards to scientific reasoning skills, students that showed high levels or reflective reasoning skills for the most part performed better on the statewide-standardized science test than students with intuitive or transitional reasoning skills. This assertion was supported by the studies conducted by Lawson and his colleagues, which showed that high levels of reasoning or reflective reasoning skills are prerequisite for most high school science courses. The findings in this study imply that high order English language proficiency combined with high levels of reasoning skills enhances students' abilities to learn science content subject matter. This

  2. Science as a second language: Analysis of Emergent Bilinguals performance and the impact of English language proficiency and first language characteristics on the Colorado measures of academic success for science

    Science.gov (United States)

    Bruno, Joanna K.

    In an age when communication is highly important and states across the nation, including Colorado, have adopted Common Core State Standards, the need for academic language is even more important than ever. The language of science has been compared to a second language in that it uses specific discourse patterns, semantic rules, and a very specific vocabulary. There is a need for educators to better understand how language impacts academic achievement, specifically concerning Emergent Bilinguals (EBs). Research has identified the need to study the role language plays in content assessments and the impact they have on EBs performance (Abedi, 2008b; Abedi, Hofestter & Lord, 2004; Abedi & Lord, 2001). Since language is the means through which content knowledge is assessed, it is important to analyze this aspect of learning. A review of literature identified the need to create more reliable and valid content assessments for EBs (Abedi, 2008b) and to further study the impact of English proficiency on EBs performance on standardized assessments (Solorzano, 2008; Wolf, & Leon, 2009). This study contributes to the literature by analyzing EBs performance on a state-level science content assessment, taking into consideration English language proficiency, receptive versus productive elements of language, and students' home language. This study further contributes by discussing the relationship between language proficiency, and the different strands of science (physical, life, and earth) on the state science assessment. Finally, this study demonstrates that home language, English language proficiency, and receptive and productive elements of language are predictive of EBs' achievement on the CMAS for science, overall and by strand. It is the blending of the social (listening and speaking) with the academic (reading and writing) that is also important and possibly more important.

    Food intake is the main route of human dioxin exposure, making the determination of dioxins in food indispensable for risk assessment and risk management of dioxins. The uncertainty of analytical results, however, can be very great because of the low concentration of the analytes and complicated cleanup procedures. The risk assessment of dioxins based on analytical results also suffers from a similar degree of uncertainty. The Ministry of Health, Labor and Welfare of Japan has published ''Guideline for the Determination of Dioxins in Food'' to standardize the analytical procedures. The guideline contains the quality assurance procedures to obtain reliable analytical results and recommends participation in the relevant proficiency testing scheme. The proficiency testing provides the fair evaluation of the analytical results. The central science laboratory in England and the food and drug safety center in Japan offer the proficiency testing on food. The National Institute of Health Sciences of Japan (NIHS) also has carried out proficiency testing of dioxins in food since 1998 to assure the quality of analytical results for dioxins. In this presentation we will show the results of 5 rounds of proficiency testing.

    The effect of intellectual impairment on sports performance has received limited attention by researchers. As a contribution to closing this gap, the purpose of the present investigation was to examine the differences in tactical proficiency between table tennis players with and without intellectual disabilities (ID). These groups were matched for training-volume and experience and consisted of 41 male (age = 27±8) and 30 female (age= 28±8) elite players with ID and a reference group of 12 male (age= 24±12) and 5 female (age= 20±9) players without ID. In two different test settings - one a World Championship and the other a training camp - the players in each group performed 60 semi-standardised rallies against the same opponent. Players were told that 12 sets of five identical services would be delivered, and their goal was to return the service with the intention of 'winning the point'. The test results were validated for this study, to compute tactical proficiency scores (maximal score of eight points) for each player. A two-way Analysis of Variance (ANOVA) revealed significantly lower proficiency scores for players with ID than for those without ID. Repeated-measures ANOVA revealed that within each series of five rallies, starting with identical services, all participants were able to significantly improve their tactical proficiency gradually, but players without ID scored 4.3±0.5 from the first ball on, and while athletes with ID only 3.3±0.7 after five balls. The results of this study indicate that ID is associated with decreased tactical proficiency in table tennis.

    Full Text Available In the written texts on foreign language learning, a group of studies has stressed the function of learning context and learning chances for learners’ language input. The present thesis had two main goals: on the one hand, different types of input to which Iranian grade four high school EFL learners’ are exposed were looked at; on the other hand, the possible relationship between types and quantity of input and Iranian EFL learners’ oral proficiency was investigated. It was supposed that EFL learners who have access to more input will show better oral proficiency than those who do not have. Instruments used in the present study for the purpose of data collation included  PET test, researcher- made questionnaire, oral language proficiency test and face- to -face interview. Data were gathered from 50 Iranian female grade four high school foreign language learners who were selected from among 120 students whose score on PET test were +1SD from the mean score. The results of the Spearman rank –order correlation test for the types of input and oral language proficiency scores, showed that the participants’ oral proficiency score significantly correlated with the intended four sources of input including spoken (rho= 0.416, sig=0.003, written (rho= 0.364, sig=0.009, aural (rho= 0.343, sig=0.015 and visual or audio-visual types of input (rho= 0.47, sig=0.00. The findings of Spearman rank –order correlation test for the quantity of input and oral language proficiency scores also showed a significant relationship between quantity of input and oral language proficiency (rho= 0.543, sig= 0.00. The findings showed that EFL learners’ oral proficiency is significantly correlated with efficient and effective input. The findings may also suggest  answers to the question why most Iranian English learners fail to speak English fluently, which might be due to  lack of effective input. This may emphasize the importance of the types and quantity of

The Reference Laboratory for Milk and Dairy Products of the Dairy Science Department, Faculty of Agriculture University of Zagreb, is itself incorporated in the proficiency testing organized by dairy laboratories from Germany, Italy, France, Switzerland and Slovenia. The aim is to find out its own accuracy and reliability in particular milk and dairy products analyses. On the basis of seven years experience of participating in proficiency testing, five years ago the Reference Laboratory started organizing its own proficiency testing for dairy laboratories in Croatia, Bosnia and Herzegovina and Macedonia for milk components such as milk fat, protein, lactose and somatic cells count. The results of the analyses have been statistically analyzed and, on the basis of Z-score, the successful measurements have been estimated. The aim of this paper is to demonstrate the organisation and data processing of proficiency testing for milk fat, protein, lactose and somatic cells count in milk for the involved dairy laboratories.

    The aim of this study is to examine the relationship between motor skill competence and body composition of 6- to 10-year-old children. Seventy girls and 86 boys participated. Body composition was measured by body mass index and skinfold thickness. Motor proficiency was evaluated through the Bruininks-Oseretsky Test of Motor Proficiency-Short Form, which included measures of gross motor skills and fine motor skills. Significant associations were found for both sexes between the percentage of body fat and (i) the performance in each gross motor task, (ii) the composite score for gross motor skills and (iii) the motor proficiency score. The percentage of body fat was not significantly associated with the majority of the fine motor skills items and with the respective composite score. Considering body weigh categories, children with normal weight had significantly higher scores than their peers with overweight or with obesity in gross motor skills and in overall motor proficiency. Children's motor proficiency is negatively associated with body fat, and normal weight children show better motor competence than those who are overweight or obese. The negative impact of excessive body weight is stronger for gross motor skills that involve dynamic body movements than for stationary object control skills; fine motor skills appear to be relatively independent of the constraints imposed by excessive body weight. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    The Association of American Medical Colleges describes 13 core entrustable professional activities (EPAs) that every graduating medical student should be expected to perform proficiently on day 1 of residency, regardless of chosen specialty. Studies have shown wide variability in program director (PD) confidence in interns' abilities to perform these core EPAs. Little is known regarding comparison of United States Medical Licensing Examination (USMLE) scores with proficiency in EPAs. We determined if PDs from a large health system felt confident in their postgraduate year 1 residents' abilities to perform the 13 core EPAs, and compared perceived EPA proficiency with USMLE Step 1 and Step 2 scores. The PDs were asked to rate their residents' proficiency in each EPA and to provide residents' USMLE scores. Timing coincided with the reporting period for resident milestones. Surveys were completed on 204 of 328 residents (62%). PDs reported that 69% of residents (140 of 204) were prepared for EPA 4 (orders/prescriptions), 61% (117 of 192) for EPA 7 (form clinical questions), 68% (135 of 198) for EPA 8 (handovers), 63% (116 of 185) for EPA 11 (consent), and 38% (49 of 129) for EPA 13 (patient safety). EPA ratings and USMLE 1 and 2 were negatively correlated ( r (101) = -0.23, P  = .031). PDs felt that a significant percentage of residents were not adequately prepared in order writing, forming clinical questions, handoffs, informed consent, and promoting a culture of patient safety. We found no positive association between USMLE scores and EPA ratings.

    Full Text Available Background and Aim: Phonological awareness (consisting of phoneme, syllable and intra-syllable awareness is an important part of receptive and expressive language; it facilitates reading and writing skills through phonological re-coding. Multiple studies in several languages have studied the relationship between phonological awareness and dictation. This research is based on a study of the relationship between phonological skill and spelling score in first-grade Persian students.Methods: Four hundred first-grade students participated in the study, including 209 girls and 191 boys. A phonological awareness test was individually administered for each student and then a spelling exam was administered in groups. The correlation between the two tests was studied using a simple regression model. The comparison of mean scores of girls and boys was evaluated employing an independent t-test.Results: A correlation coefficient of 0.82 was obtained between phonological awareness and spelling proficiency (p<0.001. Phonological skill sub-tests also showed a significant correlation with spelling proficiency (highest for phoneme awareness r=0.34 and lowest for rhyme awareness r=0.12. The mean scores of girls and boys differed significantly (p<0.05.Conclusion: There is a strong positive association between phonological awareness and spelling proficiency. Therefore, if phonological skill is improved, spelling score can be enhanced.

    Full Text Available In the Malaysian education system, English has always played an important role. In acknowledging its importance, Malaysian University English Test (MUET has been introduced to enable continued emphasis on this role.  MUET has been made compulsory for those who wish to pursue a first degree programme in local universities. This study aims to examine the relationship between English language proficiency test (as measured by MUET bands to predict the undergraduates academic achievement (as measured by Cumulative Grade Point Average score. It also aims to determine the recommended MUET band as an entry requirement for prospective technical programme undergraduates in Universiti Putra Malaysia (UPM. The study was carried out among 225 final year undergraduates of five different faculties in UPM, namely Faculty of Engineering, Faculty of Forestry, Faculty of Biotechnology and Biomolecular, Faculty of Food Science and Technology, and Faculty of Veterinary Medicine.  The data used were obtained by administering a brief questionnaire and were quantitatively analysed using Statistical Package for Social Science (SPSS version 19.  The study revealed that there is a medium positive correlation between English language proficiency and academic achievement where students who have scored higher bands for MUET are the ones who obtained higher CGPA in their study. Based on the findings, it is recommended that UPM and other local universities make changes towards the minimum MUET entry requirement to help prospective undergraduates excel in their academic study.

    The purpose of this study was to gather additional evidence for the validity and reliability of spoken English proficiency ratings provided by trained standardized patients (SPs) in high-stakes clinical skills examination. Over 2500 candidates who took the Educational Commission for Foreign Medical Graduates' (ECFMG) Clinical Skills Assessment (CSA) were studied. The CSA consists of 10 or 11 timed clinical encounters. Standardized patients evaluate spoken English proficiency and interpersonal skills in every encounter. Generalizability theory was used to estimate the consistency of spoken English ratings. Validity coefficients were calculated by correlating summary English ratings with CSA scores and other external criterion measures. Mean spoken English ratings were also compared by various candidate background variables. The reliability of the spoken English ratings, based on 10 independent evaluations, was high. The magnitudes of the associated variance components indicated that the evaluation of a candidate's spoken English proficiency is unlikely to be affected by the choice of cases or SPs used in a given assessment. Proficiency in spoken English was related to native language (English versus other) and scores from the Test of English as a Foreign Language (TOEFL). The pattern of the relationships, both within assessment components and with external criterion measures, suggests that valid measures of spoken English proficiency are obtained. This result, combined with the high reproducibility of the ratings over encounters and SPs, supports the use of trained SPs to measure spoken English skills in a simulated medical environment.

    Davis, Edward

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

    1999-01-01

    We describe the procedures for constructing an instrument designed to evaluate children's proficiency in American Sign Language (ASL). The American Sign Language Proficiency Assessment (ASL-PA) is a much-needed tool that potentially could be used by researchers, language specialists, and qualified school personnel. A half-hour ASL sample is collected on video from a target child (between ages 6 and 12) across three separate discourse settings and is later analyzed and scored by an assessor who is highly proficient in ASL. After the child's language sample is scored, he or she can be assigned an ASL proficiency rating of Level 1, 2, or 3. At this phase in its development, substantial evidence of reliability and validity has been obtained for the ASL-PA using a sample of 80 profoundly deaf children (ages 6-12) of varying ASL skill levels. The article first explains the item development and administration of the ASL-PA instrument, then describes the empirical item analysis, standard setting procedures, and evidence of reliability and validity. The ASL-PA is a promising instrument for assessing elementary school-age children's ASL proficiency. Plans for further development are also discussed.

    The present study examined Japanese university students' processing time for English subject and object relative clauses in relation to their English listening proficiency. In Analysis 1, the relation between English listening proficiency and reading span test scores was analyzed. The results showed that the high and low listening comprehension groups' reading span test scores do not differ. Analysis 2 investigated English listening proficiency and processing time for sentences with subject and object relative clauses. The results showed that reading the relative clause ending and the main verb section of a sentence with an object relative clause (such as "attacked" and "admitted" in the sentence "The reporter that the senator attacked admitted the error") takes less time for learners with high English listening scores than for learners with low English listening scores. In Analysis 3, English listening proficiency and comprehension accuracy for sentences with subject and object relative clauses were examined. The results showed no significant difference in comprehension accuracy between the high and low listening-comprehension groups. These results indicate that processing time for English relative clauses is related to the cognitive processes involved in listening comprehension, which requires immediate processing of syntactically complex audio information.

    Full Text Available This study aimed to examine motor proficiency in young children, focusing on potential gender differences. For that purpose, the Bruininks-Oseretsky Test of Motor Proficiency–Long Form (BOTMP-LF was administered to 540 children (272 boys, 4½ to 6 years old. First, the 2 (sex × 4 (age groups ANOVA computed on children’s total BOTMP-LF scores showed that age had a statistically significant effect, whereas gender did not. Second, the one-way MANCOVA applied on subtest scores, with age as covariate, revealed statistical significant gender differences; however, η2 values were found to be small or moderate. Finally, the MANCOVA applied on items where significant gender differences have been reported showed a significant effect of gender. Nonetheless, η2 values exceeded the limit of practical significance only on two items (“standing on preferred leg on floor”, “throwing a ball at a target with preferred hand” that are associated with gender-stereotyped activities. It can be concluded that (a besides statistical significance, effect sizes should be examined for the results of a study to be adequately interpreted; (b young boys’ and girls’ motor proficiency is similar rather than different. Gender differences in specific skills should be used for movement programs to be individualized.

    Full Text Available Writing is an essential skill for academic development within any disciplinary area. Despite the rapidly growing body of research on the various aspects of second language writing, research on writing self-efficacy remains scarce. This study investigated the relationship the between writing self-efficacy and writing proficiency in English as a second language. In this cross-sectional study, 304 Malaysian undergraduate students completed a writing self-efficacy questionnaire. The participants’ writing proficiency was assessed using two different writing tasks. The results showed that there was a significant difference in writing self-efficacy among the three writing proficiency groups. It was also found that science students had significantly higher writing self-efficacy than those in social sciences. Limitations of the study and Implications for second language writing instruction are also discussed.

    All medical schools in Saudi Arabia have English as the primary official medium of instruction. Most of the high school education, however, is delivered in Arabic and hence the transition to an English based learning environment tends to be difficult for some students. Our study aims to correlate English language proficiency with academic performance among medical students in their preparatory year. A cross-sectional study design was used. Test scores of 103 preparatory year students (54 female and 49 male) were analyzed after the students completed an English language course and medical introductory course in their preparatory year. The total score obtained in the English course assessment was compared to each component of the medical content assessment. A significantly positive correlation (Spearman's Rho, at 0.01 levels) was seen between the scores of the English exam and the written exam (P English exam score was not obtained for the other components of the medical assessment, namely; student assignments, presentations and portfolios. English language proficiency is an important factor in determining academic proficiency of medical students in our college at the preparatory year level.

    Through the review of creativity research I have found that studies lack certain crucial parts: (a) a theoretical framework for the study of creativity in science, (b) studies considering the unique components related to scientific creativity, and (c) studies of the interactions among key components through simultaneous analyses. The primary purpose of this study is to explore the dynamic interactions among four components (scientific proficiency, intrinsic motivation, creative competence, context supporting creativity) related to scientific creativity under the framework of scientific creativity. A total of 295 Korean middle school students participated. Well-known and commonly used measurements were selected and developed. Two scientific achievement scores and one score measured by performance-based assessment were used to measure student scientific knowledge/inquiry skills. Six items selected from the study of Lederman, Abd-El-Khalick, Bell, and Schwartz (2002) were used to assess how well students understand the nature of science. Five items were selected from the subscale of the scientific attitude inventory version II (Moore & Foy, 1997) to assess student attitude toward science. The Test of Creative Thinking-Drawing Production (Urban & Jellen, 1996) was used to measure creative competence. Eight items chosen from the 15 items of the Work Preference Inventory (1994) were applied to measure students' intrinsic motivation. To assess the level of context supporting creativity, eight items were adapted from measurement of the work environment (Amabile, Conti, Coon, Lazenby, and Herron, 1996). To assess scientific creativity, one open-ended science problem was used and three raters rated the level of scientific creativity through the Consensual Assessment Technique (Amabile, 1996). The results show that scientific proficiency and creative competence correlates with scientific creativity. Intrinsic motivation and context components do not predict scientific

    1990-10-01

    The report lists those individual contractors in the United States who have met the requirements of the Radon Contractor Proficiency (RCP) Program as of August 18, 1990. These requirements are designed to provide minimum proficiency criteria for individuals who design and supervise the installation of radon mitigation systems in buildings. (Some States have more stringent requirements as part of their radon certification programs. The States should be consulted directly for details on their programs; see Section 5 for a list of State radon contacts). The RCP Program measures the proficiency of an individual contractor, not their company. Therefore, users of the report who select a mitigation firm should ensure that the services are provided by the listed contractor. The National RCP Program does not accredit mitigation contractors, nor does it certify, recommend, or endorse participating companies. Only the listed contractor, not their company of affilation, are deemed proficient. The inclusion of a contractor in the report should not be interpreted as a certification or accreditation of the individual or affiliated company

    The primary objective of the U.S. Environmental Protection Agency's (EPA) efforts to address the indoor radon problem is to reduce radon levels in buildings throughout the country. Achieving the objective requires a nationwide supply of capable radon mitigation contractors. In the Indoor Radon Abatement Act of 1988, Congress authorized EPA to establish a program to evaluate radon mitigation contractors and to provide the information to the public in cooperation with the States. The Radon Contractor Proficiency (RCP) Program was developed to assist States, EPA Regions, local government officials, and the public in selecting contractors who have demonstrated their proficiency in reducing indoor radon levels. The program is managed by the EPA Office of Radiation Programs' Radon Division. Under the voluntary program, radon contractors demonstrate their proficiency by meeting specific Program requirements. Individual contractors who meet these requirements are then listed in periodic RCP Proficiency Reports

    Laparoscopic simulator training translates into improved operative performance. Proficiency-based curricula maximize efficiency by tailoring training to meet the needs of each individual; however, because rates of skill acquisition vary widely, such curricula may be difficult to implement. We hypothesized that psychomotor testing would predict baseline performance and training duration in a proficiency-based laparoscopic simulator curriculum. Residents (R1, n = 20) were enrolled in an IRB-approved prospective study at the beginning of the academic year. All completed the following: a background information survey, a battery of 12 innate ability measures (5 motor, and 7 visual-spatial), and baseline testing on 3 validated simulators (5 videotrainer [VT] tasks, 12 virtual reality [minimally invasive surgical trainer-virtual reality, MIST-VR] tasks, and 2 laparoscopic camera navigation [LCN] tasks). Participants trained to proficiency, and training duration and number of repetitions were recorded. Baseline test scores were correlated to skill acquisition rate. Cutoff scores for each predictive test were calculated based on a receiver operator curve, and their sensitivity and specificity were determined in identifying slow learners. Only the Cards Rotation test correlated with baseline simulator ability on VT and LCN. Curriculum implementation required 347 man-hours (6-person team) and 795,000 dollars of capital equipment. With an attendance rate of 75%, 19 of 20 residents (95%) completed the curriculum by the end of the academic year. To complete training, a median of 12 hours (range, 5.5-21), and 325 repetitions (range, 171-782) were required. Simulator score improvement was 50%. Training duration and repetitions correlated with prior video game and billiard exposure, grooved pegboard, finger tap, map planning, Rey Figure Immediate Recall score, and baseline performance on VT and LCN. The map planning cutoff score proved most specific in identifying slow learners

    Full Text Available Laboratory for analysis of mycotoxins in food at the Institute of Public Health of Vojvodina (Novi Sad, Serbia participated in 15 proficiency testing schemes in period 2012-2016, comprising 22 determinations of regulated mycotoxins: aflatoxins B1, B2, G1, G2 and M1, ochratoxin A, deoxynivalenone, zearalenone, fumonisins and patulin, in different food commodities: wheat, corn, barley, breakfast cereals, infant food, milk, wine and fruit juice. Analyses were carried out by high performance liquid chromatography with ultraviolet (patulin, deoxynivalenol or fluorescence detection (aflatoxin M1, ochratoxin A, zearalenone using o-phthalaldehyde precolumn derivatization (fumonisins or UV postcolumn derivatization (aflatoxins B1, B2, G1, G2, following clean-up on immunoaffinity columns with specific antibodies, except in case of patulin when solvent extraction and solid-phase C-18 clean-up were used. Laboratory performance assessed in terms of z scores showed all satisfactory results. In depth evaluation revealed following distribution of z scores (absolute values: 59.1% up to 0.5, 36.4% between 0.5 and 1.0, and 4.5% above 1.0. Analysis of trends performed for multiple determinations of individual mycotoxins showed several changes of z score to better or worse rank. Overall assessment of the performance in proficiency testing demonstrated laboratory competence for analysis of mycotoxins in food.

    In an effort to improve instruction and student learning, school reform efforts have become prevalent. School reformers have examined many aspects of the school experience, including learning theories such as behaviorism and constructivism, the changing roles of teachers and supervisors, and even the concept of the school itself. The theoretical framework for this study centered around constructivist learning theory. The study itself focused on the application of constructivist learning theory to the supervisory process. The study examined five areas of interest: (a) teachers' perceptions of constructivist supervisory behavior; (b) teachers' perceptions of efficacy and control in the classroom; (c) teachers' perceptions of school climate; (d) teachers' perceptions of job satisfaction, and (e) the influences of each of the aforementioned on student proficiency in mathematics, reading, and science. Data for the study was drawn from the first follow-up survey of the National Educational Longitudinal Study of 1988 (NELS: 88). NELS: 88 investigated a wide variety of factors that influence the educational process. The first follow-up focuses on environmental factors that affect teachers and students. Variables were selected from the NELS:88 data set that represented the areas to be examined. Factor analysis and correlational analysis were applied to ensure that the variables were measuring distinct constructs and to determine ways they could be grouped for analysis. Multiple linear regression analysis was applied to determine relationships among the individual and composite variables, controlling for student and teacher demographic factors. The results of the study suggest that varying relationships do exist between constructivist supervisory practices and the constructs measuring school climate and job satisfaction. The results also suggest that varying relationships exist between each of these factors and student proficiency in mathematics, reading, and science

    Fine motor skill proficiency is an essential component of numerous daily living activities such as dressing, feeding or playing. Poor fine motor skills can lead to difficulties in academic achievement, increased anxiety and poor self-esteem. Recent findings have shown that children's gross motor skill proficiency tends to fall below established developmental norms. A question remains: do fine motor skill proficiency levels also fall below developmental norms? The aim of this study was to examine the current level of fine motor skill in Irish children. Children (N=253) from 2nd, 4th and 6th grades (mean age=7.12, 9.11 and 11.02 respectively) completed the Fine Motor Composite of the Bruininks Oseretsky Test of Motor Proficiency 2nd Edition (BOT-2). Analysis revealed that only 2nd grade children met the expected level of fine motor skill proficiency. It was also found that despite children's raw scores improving with age, children's fine motor skill proficiency was not progressing at the expected rate given by normative data. This leads us to question the role and impact of modern society on fine motor skills development over the past number of decades. Copyright © 2015 Elsevier B.V. All rights reserved.

    Frias, Ramon

    The No Child Left Behind Act (NCLB)'s emphasis of reading, language arts, and mathematics (RLA&M) and its de-emphasis of science has been a source of great concern among educators. Through an objectivist and constructionist framework, this study explored the unforeseen effects of the NCLB on public science education among Title I (TI) and non-Title I (NTI) students. The research questions focused on the effects of NCLB on Criterion Referenced Competency Test (CRCT) scores in the high-stakes subjects of reading, language arts, mathematics and the low stakes subject of science among TI and NTI 3rd, 4th, and 5th grade students in a north Georgia County during the 2010/2011 school year. This study also compared instructional time TI and NTI teachers dedicated to science. A causal-comparative quantitative methodology was used to analyze Georgia's public domain CRCT scores. Three independent-samples t tests showed that TI schools exhibited significantly lower Science CRCT scores than did NTI students at all grade levels (p need students with strong science foundations. Further study is recommended to analyze the factors associated with this science gap between TI and NTI students.

    When nurses who are educated internationally immigrate to the United States, they are expected to have English language proficiency in order to function as a competent nurse. The purpose of this research was to provide sufficient information to the National Council of State Boards of Nursing (NCSBN) to make a defensible recommended passing standard for English proficiency. This standard was based upon the Test of English as a Foreign Language (TOEFL). A large panel of nurses and nurse regulators (N = 25) was convened to determine how much English proficiency is required to be minimally competent as an entry-level nurse. Two standard setting procedures, the Simulated Minimally Competent Candidate (SMCC) procedure and the Examinee Paper Selection Method, were combined to produce recommendations for each panelist. In conjunction with collateral information, these recommendations were reviewed by the NCSBN Examination Committee, which decided upon an NCSBN recommended standard, a TOEFL score of 220. Because the adoption of this standard rests entirely with the individual state, NCSBN has little more to do with implementing the standard, other than answering questions and providing documentation about the standard.

    This study aims to assess fundamental movement skill (FMS) proficiency, physical self-confidence levels, and the relationship between these variables and gender differences among adolescents. Three hundred and ninety five adolescents aged 13.78 years (SD = ±1.2) from 20 schools were involved in this study. The Test of Gross Motor Development-2nd Edition (TGMD), TGMD-2 and Victorian Skills Manual were used to assess 15 FMS. Participants' physical self-confidence was also assessed using a valid skill-specific scale. A significant correlation was observed between FMS proficiency and physical self-confidence for females only (r = 0.305, P < 0.001). Males rated themselves as having significantly higher physical self-confidence levels than females (P = 0.001). Males scored significantly higher than females in FMS proficiency (P < 0.05), and the lowest physical self-confidence group were significantly less proficient at FMS than the medium (P < 0.001) and high physical self-confidence groups (P < 0.05). This information not only highlights those in need of assistance to develop their FMS but will also facilitate in the development of an intervention which aims to improve physical self-confidence and FMS proficiency.

    This work reports the analysis and main results of a recently concluded proficiency testing round with the major electromagnetic compatibility (EMC) laboratories in Brazil. Seven labs conducted radiated emission measurements at their test facilities under the coordination of an independent third party supervised by the Brazilian accreditation body, INMETRO. Six of them are currently the only labs accredited on EMC measurements in Brazil. The guidelines of international standards such as ISO/IEC Guide 43 and ISO 13528 were followed, while the scope of the tests focused on EMC compliance of information technology devices, based on CISPR 22. A multi-tone signal generator was specifically designed and assembled for the present proficiency testing conditions. Statistical metrics such as z-score and normalized error have been adopted to assess global and individual performances of the participant laboratories. The normalized error indicated 10 unacceptable results out of 35 results, while only 3 out of 35 z-scores were out of the acceptance range. Considering that the participant labs are actually only for test measurements (not for calibration), the overall performance may be taken as satisfactory, based on the fact that the z-score should be used in this case

    Universities in Thailand are preparing for Thailand's integration into the ASEAN Economic Community (AEC) by increasing the number of tests in English language. English language is not the native language of Thailand Differences in English language proficiency may affect scores among test-takers, even when subject knowledge among test-takers is comparable and may falsely represent the knowledge level of the test-taker. To study the impact of English language multiple choice test questions on test scores of medical students. The final examination of fourth-year medical students completing internal medicine rotation contains 120 multiple choice questions (MCQ). The languages used on the test are Thai and English at a ratio of 3:1. Individual scores of tests taken in both languages were collected and the effect of English language on MCQ was analyzed Individual MCQ scores were then compared with individual student English language proficiency and student grade point average (GPA). Two hundred ninety five fourth-year medical students were enrolled. The mean percentage of MCQ scores in Thai and English were significantly different (65.0 ± 8.4 and 56.5 ± 12.4, respectively, p English was fair (Spearman's correlation coefficient = 0.41, p English than in Thai language. Students were classified into six grade categories (A, B+, B, C+, C, and D+), which cumulatively measured total internal medicine rotation performance score plus final examination score. MCQ scores from Thai language examination were more closely correlated with total course grades than were the scores from English language examination (Spearman's correlation coefficient = 0.73 (p English proficiency score was very high, at 3.71 ± 0.35 from a total of 4.00. Mean student GPA was 3.40 ± 0.33 from a possible 4.00. English language MCQ examination scores were more highly associated with GPA than with English language proficiency. The use of English language multiple choice question test may decrease scores

    To determine whether childhood fundamental motor skill proficiency predicts subsequent adolescent cardiorespiratory fitness. In 2000, children's proficiency in a battery of skills was assessed as part of an elementary school-based intervention. Participants were followed up during 2006/2007 as part of the Physical Activity and Skills Study, and cardiorespiratory fitness was measured using the Multistage Fitness Test. Linear regression was used to examine the relationship between childhood fundamental motor skill proficiency and adolescent cardiorespiratory fitness controlling for gender. Composite object control (kick, catch, throw) and locomotor skill (hop, side gallop, vertical jump) were constructed for analysis. A separate linear regression examined the ability of the sprint run to predict cardiorespiratory fitness. Of the 928 original intervention participants, 481 were in 28 schools, 276 (57%) of whom were assessed. Two hundred and forty-four students (88.4%) completed the fitness test. One hundred and twenty-seven were females (52.1%), 60.1% of whom were in grade 10 and 39.0% were in grade 11. As children, almost all 244 completed each motor assessments, except for the sprint run (n = 154, 55.8%). The mean composite skill score in 2000 was 17.7 (SD 5.1). In 2006/2007, the mean number of laps on the Multistage Fitness Test was 50.5 (SD 24.4). Object control proficiency in childhood, adjusting for gender (P = 0.000), was associated with adolescent cardiorespiratory fitness (P = 0.012), accounting for 26% of fitness variation. Children with good object control skills are more likely to become fit adolescents. Fundamental motor skill development in childhood may be an important component of interventions aiming to promote long-term fitness.

    Wiggins, Felita

    Student achievement in the Twenty First Century demands a new rigor in student science knowledge, since advances in science and technology require students to think and act like scientists. As a result, students must acquire proficient levels of knowledge and skills to support a knowledge base that is expanding exponentially with new scientific advances. This study examined the effects of hands-on-science instruction on the science achievement of middle school students. More specifically, this study was concerned with the influence of hands-on science instruction versus traditional science instruction on the science test scores of middle school students. The subjects in this study were one hundred and twenty sixth-grade students in six classes. Instruction involved lecture/discussion and hands-on activities carried out for a three week period. Specifically, the study ascertained the influence of the variables gender, ethnicity, and socioeconomic status on the science test scores of middle school students. Additionally, this study assessed the effect of the variables gender, ethnicity, and socioeconomic status on the attitudes of sixth grade students toward science. The two instruments used to collect data for this study were the Prentice Hall unit ecosystem test and the Scientific Work Experience Programs for Teachers Study (SWEPT) student's attitude survey. Moreover, the data for the study was treated using the One-Way Analysis of Covariance and the One-Way Analysis of Variance. The following findings were made based on the results: (1) A statistically significant difference existed in the science performance of middle school students exposed to hands-on science instruction. These students had significantly higher scores than the science performance of middle school students exposed to traditional instruction. (2) A statistically significant difference did not exist between the science scores of male and female middle school students. (3) A statistically

    Mobile device proficiency is increasingly required to participate in society. Unfortunately, there still exists a digital divide between younger and older adults, especially with respect to mobile devices (i.e., tablet computers and smartphones). Training is an important goal to ensure that older adults can reap the benefits of these devices. However, efficient/effective training depends on the ability to gauge current proficiency levels. We developed a new scale to accurately assess the mobile device proficiency of older adults: the Mobile Device Proficiency Questionnaire (MDPQ). We present and validate the MDPQ and a short 16-question version of the MDPQ (MDPQ-16). The MDPQ, its subscales, and the MDPQ-16 were found to be highly reliable and valid measures of mobile device proficiency in a large sample. We conclude that the MDPQ and MDPQ-16 may serve as useful tools for facilitating mobile device training of older adults and measuring mobile device proficiency for research purposes.

    The primary objective of the U.S. Environmental Protection Agency's (EPA) efforts to address the indoor radon problem is to reduce radon levels in buildings throughout the country. Achieving this objective requires a nationwide supply of capable radon mitigation contractors. In the Indoor Radon Abatement Act of 1988, Congress authorized EPA to establish a program to evaluate radon mitigation contractors and to provide this information to the public in cooperation with the States. The Radon Contractor Proficiency (RCP) Program was developed to assist States, EPA Regions, local government officials, and the public in selecting contractors who have demonstrated their proficiency in reducing indoor radon levels. The program is managed by the EPA Office of Radiation Programs' Radon Division. Under this voluntary program, radon contractors demonstrate their proficiency by meeting specific Program requirements. Individual contractors who meet these requirements are then listed in the Report

    The clinical application of robotic surgery is increasing. The skills necessary to perform robotic surgery are unique from those required in open and laparoscopic surgery. A validated laparoscopic surgical skills curriculum (Fundamentals of Laparoscopic Surgery or FLS™) has transformed the way surgeons acquire laparoscopic skills. There is a need for a similar skills training and assessment tool for robotic surgery. Our research group previously developed and validated a robotic training curriculum in a virtual reality (VR) simulator. We hypothesized that novice robotic surgeons could achieve proficiency levels defined by more experienced robotic surgeons on the VR robotic curriculum, and that this would result in improved performance on the actual daVinci Surgical System™. 25 medical students with no prior robotic surgery experience were recruited. Prior to VR training, subjects performed 2 FLS tasks 3 times each (Peg Transfer, Intracorporeal Knot Tying) using the daVinci Surgical System™ docked to a video trainer box. Task performance for the FLS tasks was scored objectively. Subjects then practiced on the VR simulator (daVinci Skills Simulator) until proficiency levels on all 5 tasks were achieved before completing a post-training assessment of the 2 FLS tasks on the daVinci Surgical System™ in the video trainer box. All subjects to complete the study (1 dropped out) reached proficiency levels on all VR tasks in an average of 71 (± 21.7) attempts, accumulating 164.3 (± 55.7) minutes of console training time. There was a significant improvement in performance on the robotic FLS tasks following completion of the VR training curriculum. Novice robotic surgeons are able to attain proficiency levels on a VR simulator. This leads to improved performance in the daVinci surgical platform on simulated tasks. Training to proficiency on a VR robotic surgery simulator is an efficient and viable method for acquiring robotic surgical skills.

    To compare the effectiveness of a core stability program with a task-oriented motor training program in improving motor proficiency in children with developmental coordination disorder (DCD). Randomized controlled pilot trial. Outpatient unit in a hospital. Twenty-two children diagnosed with DCD aged 6-9 years were randomly allocated to the core stability program or the task-oriented motor program. Both groups underwent their respective face-to-face training session once per week for eight consecutive weeks. They were also instructed to carry out home exercises on a daily basis during the intervention period. Short Form of the Bruininks-Oseretsky Test of Motor Proficiency (Second Edition) and Sensory Organization Test at pre- and post-intervention. Intention-to-treat analysis revealed no significant between-group difference in the change of motor proficiency standard score (P=0.717), and composite equilibrium score derived from the Sensory Organization Test (P=0.100). Further analysis showed significant improvement in motor proficiency in both the core stability (mean change (SD)=6.3(5.4); p=0.008) and task-oriented training groups (mean change(SD)=5.1(4.0); P=0.007). The composite equilibrium score was significantly increased in the task-oriented training group (mean change (SD)=6.0(5.5); P=0.009), but not in the core stability group (mean change(SD) =0.0(9.6); P=0.812). In the task-oriented training group, compliance with the home program was positively correlated with change in motor proficiency (ρ=0.680, P=0.030) and composite equilibrium score (ρ=0.638, P=0.047). The core stability exercise program is as effective as task-oriented training in improving motor proficiency among children with DCD. © The Author(s) 2014.

    The number of patients in the United States (US) who speak a language other than English is increasing. We evaluated the impact of English proficiency on self-reported patient-provider communication and shared decision-making. The 2013-2014 Medical Expenditure Panel Survey database was utilized to identify respondents who spoke a language other than English. Patient-provider communication (PPC) and shared decision-making (SDM) scores from 4-12 were categorized as "poor" (4-7), "average" (8-11), and "optimal." The relationship between PPC, SDM, and English proficiency was analyzed. Among 13,880 respondents, most were white (n = 10,281, 75%), age 18-39 (n = 6,677, 48%), male (n = 7,275, 52%), middle income (n = 4,125, 30%), and born outside of the US (n = 9,125, 65%). English proficiency was rated as "very well" (n = 7,221, 52%), "well" (n = 2,378, 17%), "not well" (n = 2,820, 20%), or "not at all" (n = 1,463, 10%). On multivariable analysis, patients who rated their English as "well" (OR 1.73, 95% CI 1.37-2.18) or "not well" (OR 1.53, 95% CI 1.10-2.14) were more likely to report "poor" PPC (both P English proficiency as "not well" (OR 1.31, 95% CI 1.04-1.65, P = .02). Decreased English proficiency was associated with worse self-reported patient-provider communication and shared decision-making.

    Full Text Available Motivation raising strategies are frequently used in English as a Foreign Language (EFL classes; nevertheless, learners’ perceptions of such strategies used by language teachers have not sufficiently been explored. Also, there are not enough studies on differences and similarities between more and less proficient EFL learners regarding this issue. To scrutinize this topic, a groups of more (No=50 and less proficient EFL learners (No=50 participated in this study by completing to a validated, researcher-made questionnaire with a five-point Likert type format. Non-parametric Mann-Whiteny U test was run in the SPSS ver. 23 to check the differences between the two groups. The results of the study verified that, regardless of each individual scale in the utilized questionnaire, overall, the more proficient ones manifested significantly less perceptions on teachers’ motivation raising strategies based on the total estimated mean ranks compared with the less proficient learners.  However, within the surveyed scales, only in the classroom atmosphere scale, the results showed that the less proficient learners were more mindful of teacher strategies for motivation raising. The findings from this study have implications for motivation raising strategy instructions for a language classroom.

  19. Elementary Teachers' Perceptions of Teaching Science to Improve Student Content Knowledge

    Science.gov (United States)

    Stephenson, Robert L.

    The majority of Grade 5 students demonstrate limited science knowledge on state assessments. This trend has been documented since 2010 with no evidence of improvement. Because state accountability formulas include proficiency scores and carry sanctions against districts that fail to meet proficiency thresholds, improved student performance in science is an important issue to school districts. The purpose of this study was to explore elementary teachers' perceptions about their students' science knowledge, the strategies used to teach science, the barriers affecting science teaching, and the self-efficacy beliefs teachers maintain for teaching science. This study, guided by Vygotsky's social constructivist theory and Bandura's concept of self-efficacy, was a bounded instrumental case study in which 15 participants, required to be teaching K-5 elementary science in the county, were interviewed. An analytic technique was used to review the qualitative interview data through open coding, clustering, and analytical coding resulting in identified categorical themes that addressed the research questions. Key findings reflect students' limited content knowledge in earth and physical science. Teachers identified barriers including limited science instructional time, poor curricular resources, few professional learning opportunities, concern about new state standards, and a lack of teaching confidence. To improve student content knowledge, teachers identified the need for professional development. The project is a professional development series provided by a regional education service agency for K-5 teachers to experience science and engineering 3-dimensional learning. Area students will demonstrate deeper science content knowledge and benefit from improved science instructional practice and learning opportunities to become science problem solvers and innovative contributors to society.

  20. Assessment practices of third- and fifth-grade science teachers: A comparison to the style/format, process, and content of Ohio's proficiency tests

    Science.gov (United States)

    Janson, David C.

    This descriptive study is addressed to policy-makers, textbook publisher, teachers, principals, and curriculum directors. It compares the assessment practices of ten elementary teachers over a period of 11 weeks with Ohio's fourth and sixth grade science Proficiency Tests. Results show that the teachers' assessment practices were not aligned with Ohio's Proficiency Test. The tests used in the participants' classroom contained a disproportionate number of items characterized as low-level in terms of their cognitive function. Classroom test items generally fell into three categories---true/false, completion, and matching. The remaining items were predominantly low-level multiple-choice items requiring simple recall of information. The teachers in this study showed a heavy reliance on the packaged assessments that accompanied their adopted textbook series with little use of teacher-designed instruments. This differs from the findings of previous researchers who reported that most teacher assessments were done with teacher-made tests. The lack of alignment between classroom tests and Ohio's Proficiency Test is a concern because previous researchers and the teachers in this study believe that aligning classroom tests with high-stakes assessment improves student performance. Other research shows teachers teach what they test suggesting that the curriculum would be better aligned with State expectations if classroom tests were more in line with the proficiency tests. This study found that textbooks and their assessment packages are not aligned to most state standards and that teachers need help developing better assessments. The results of this study suggest directions school administrators might take to facilitate inservice training for current teachers and could be helpful to textbook publishers as well as educators serving on adoption committees. Since high-stakes testing of students in the nation's public schools and school accountability seem destined to remain a

    The effect of high school study of mathematics on numeracy performance of sports and exercise science (SES) students is not clear. To investigate this further, we tested the numeracy skills of 401 students enrolled in a Bachelor of Health Sciences degree in SES using a multiple-choice survey consisting of four background questions and 39 numeracy test questions. Background questions (5-point scale) focused on highest level of mathematics studied at high school, self-perception of mathematics proficiency, perceived importance of mathematics to SES and likelihood of seeking help with mathematics. Numeracy questions focused on rational number, ratios and rates, basic algebra and graph interpretation. Numeracy performance was based on answers to these questions (1 mark each) and represented by the total score (maximum = 39). Students from first (n = 212), second (n = 78) and third (n = 111) years of the SES degree completed the test. The distribution of numeracy test scores for the entire cohort was negatively skewed with a median (IQR) score of 27(11). We observed statistically significant associations between test scores and the highest level of mathematics studied (P Mathematics (20 (9)), intermediate in students who studied Year 12 General Mathematics (26 (8)) and highest in two groups of students who studied higher-level Year 12 Mathematics (31 (9), 31 (6)). There were statistically significant associations between test scores and level of self-perception of mathematics proficiency and also likelihood of seeking help with mathematics (P mathematics to SES. These findings reveal that the level of mathematics studied in high school is a critical factor determining the level of numeracy performance in SES students.

    Background Proficiency testing (PT) is a means of verifying the reliability of laboratory results, but such programmes are not readily available to laboratories in developing countries. This project provided PT to laboratories in Nigeria. Objectives To assess the proficiency of laboratories in the diagnosis of HIV, tuberculosis and malaria. Methods This was a prospective study carried out between 2009 and 2011. A structured questionnaire was administered to 106 randomly-selected laboratories. Forty-four indicated their interest in participation and were enrolled. Four rounds of pre-characterised plasma panels for HIV, sputum films for tuberculosis and blood films for malaria were distributed quarterly by courier over the course of one year. The results were returned within two weeks and scores of ≥ 80% were reported as satisfactory. Mentoring was offered after the first and second PT rounds. Results Average HIV PT scores increased from 74% to 95% from the first round to the third round, but decreased in the fourth round. For diagnosis of tuberculosis, average scores increased from 42% in the first round to 78% in the second round; but a decrease to 34% was observed in the fourth round. Malaria PT performance was 2% at first, but average scores increased between the second and fourth rounds, culminating in a fourth-round score of 39%. Many participants requested training and mentoring. Conclusions There were gross deficiencies in the quality of laboratory services rendered across Nigeria. In-country PT programmes, implemented in conjunction with mentoring, will improve coverage and diagnosis of HIV, tuberculosis and malaria. PMID:29043176

    Evidence suggests that early proficiency in the language of school instruction is an important predictor of academic success for bilingual children. This study investigated whether English-proficiency at 4-5 years of age predicts academic language and literacy skills among Australian bilingual children at 10-11 years of age, as part of the Longitudinal Study of Australian Children ( LSAC, 2012 ). The LSAC comprises a nationally representative clustered cross-sequential sample of Australian children. Data were analysed from a sub-sample of 129 bilingual children from the LSAC Kindergarten cohort (n = 4983), for whom teachers completed the Australian Early Development Index (AEDI) checklist (a population measure of early childhood development) and the Academic Rating Scale (ARS) language and literacy subscale. Linear regression analyses revealed that bilingual children who commenced school with stronger English proficiency had higher academic language and literacy scores at the end of primary school (β = 0.45). English proficiency remained a significant predictor, even when accounting for gender and socio-economic disadvantage (β = 0.38). The findings indicate that bilingual children who begin school without English proficiency are at risk of difficulties with academic language and literacy, even after 6 years of schooling. Risk factors need to be identified so early support can be targeted towards the most vulnerable children.

    The importance of language in mathematics learning has been widely acknowledged. However, little is known about how to make this insight productive in the design and enactment of language-oriented mathematics education. In a design-based research project, we explored how language-oriented mathematics education can be designed and enacted. We drew on genre pedagogy to promote student proficiency in the language required for interpreting line graphs. In the intervention, the teacher used scaffolding strategies to focus students' attention on the structure and linguistic features of the language involved in this particular domain. The research question addressed in this paper is how student proficiency in this language may be promoted. The study comprised nine lessons involving 22 students in grades 5 and 6 (aged 10-12); of these students, 19 had a migrant background. In light of the research aim, we first describe the rationale behind our design. Next, we illustrate how the design was enacted by means of a case study focusing on one student in the classroom practice of developing proficiency in the language required for interpreting line graphs. On the basis of pre- and posttest scores, we conclude that overall their proficiency has increased. Together, the results indicate that and how genre pedagogy may be used to help students become more proficient in the language required in a mathematical domain.

    Studies of graduate students learning to administer the Wechsler scales have generally shown that training is not associated with the development of scoring proficiency. Many studies report on the reduction of aggregated administration and scoring errors, a strategy that does not highlight the reduction of errors on subtests identified as most prone to error. This study evaluated the development of scoring proficiency specifically on the Wechsler (WISC-IV and WAIS-III) Vocabulary, Comprehension, and Similarities subtests during training by comparing a set of 'early test administrations' to 'later test administrations.' Twelve graduate students enrolled in an intelligence-testing course participated in the study. Scoring errors (e.g., incorrect point assignment) were evaluated on the students' actual practice administration test protocols. Errors on all three subtests declined significantly when scoring errors on 'early' sets of Wechsler scales were compared to those made on 'later' sets. However, correcting these subtest scoring errors did not cause significant changes in subtest scaled scores. Implications for clinical instruction and future research are discussed.

    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.

    Full Text Available By administering Simon, Simon switching, and operation-span working memory tasks to Cantonese-English bilingual children who varied in their first-language (L1, Cantonese and second-language (L2, English proficiencies, as quantified by standardized vocabulary test performance, the current study examined the effects of L1 and L2 proficiency on attentional control performance. Apart from mean performance, we conducted ex-Gaussian analyses to capture the modal and positive-tail components of participants’ reaction time distributions in the Simon task. Bilinguals’ L2 proficiency was associated with higher scores in the operation span task, and a shift of reaction time distributions in incongruent trials, relative to congruent trials (Simon effect in µ, and the tail size of reaction time distributions (τ regardless of trial types. Bilinguals’ L1 proficiency, which was strongly associated with participants’ age, showed similar results, except that it was not associated with the Simon effect in µ. In contrast, neither bilinguals’ L1 nor L2 proficiency modulated the global switch cost or local switch cost in the Simon switching task. After taking into account potential cognitive maturation by partialling out the participants’ age, only (a scores in the working memory task and (b RT in incongruent trials and (c Simon effect in µ in the Simon task could still be predicted by bilinguals’ L2 proficiency. Overall, the current findings suggest that bilingual children’s L2 proficiency was associated with their conflict resolution and working memory capacity, but not goal maintenance or task-set switching, when they performed the cognitive tasks that demanded attentional control. This was not entirely consistent with the findings of college-age bilinguals reported in previous studies.

    Full Text Available This study explored metacognitive awareness level of University of Botswana students in the Faculty of Social Sciences. It also considered the more recent research focusing on the role of metacognitive awareness in reading and how it relates to proficiency. The following questions are addressed: (1 What are the self-reported reading proficiencies of the University of Botswana students? (2 Are the University of Botswana students aware of their metacognitive reading strategies? (3 What kind of metacognitive reading strategies are frequently used? (4 Is there a difference in metacognitive awareness of reading strategies used by high- and low-proficiency students respectively? The Survey of Reading Strategies Questionnaire (SORS developed by Mokhtari and Sheorey (2002, and the semi-structured interview technique were used to collect data for this study. The findings indicate that University of Botswana English as Second Language (ESL students reported high reading proficiency and high use of metacognitive strategies, but there was no vast difference in terms of proficiency. Students who reported their proficiency as high had an edge over low-proficiency ones mainly because their management and monitoring of reading was guided more by the goals they have set themselves than by the tests and assignments they were supposed to write.

    Objectives: To determine the relationship between motor proficiency and physical activity levels in adolescent Senior Phase learners in Potchefstroom, South Africa. No literature exists on the relationship between motor proficiency and physical activity levels among South African adolescents. Method: A total of 239 13- to 14-year-old learners were assessed using the Bruininkse Oseretsky Test of Motor Proficiency 2 (BOT-2 for motor proficiency, and the International Physical Activity Questionnaire (IPAQ for physical activity levels. Data analysis included descriptive statistics, Spearman correlation coefficients and effect sizes. Results: Statistically and practically significant correlations were found between the total BOT-2 score and the physical activity levels of the total group, as well as the boys and the girls respectively. Fine motor coordination correlated with physical activity levels in the girls, while manipulation coordination correlated with the physical activity levels of the total group and the boys. The body coordination skill of jumping in place and the strength test items showed strong correlations with physical activity in all the groups. Conclusion: The motor skills of Senior Phase learners, especially coordination and strength skills, should be developed and maintained in the Physical Education curriculum to enhance physical activity levels.

    Full Text Available The present study investigates, (i English as Foreign Language (EFL learners’ receptive collocational knowledge growth in relation to their linguistic proficiency level; (ii how much receptive collocational knowledge is acquired as proficiency develops; and (iii the extent to which receptive knowledge of collocations of EFL learners varies across word frequency bands. A proficiency measure and a collocation test were administered to English majors at the University of Burundi. Results of the study suggest that receptive collocational competence develops alongside EFL learners’ linguistic proficiency; which lends empirical support to Gyllstad (2007, 2009 and Author (2011 among others, who reported similar findings. Furthermore, EFL learners’ collocations growth seems to be quantifiable wherein both linguistic proficiency level and word frequency occupy a crucial role. While more gains in terms of collocations that EFL learners could potentially add as a result of change in proficiency are found at lower levels of proficiency; collocations of words from more frequent word bands seem to be mastered first, and more gains are found at more frequent word bands. These results confirm earlier findings on the non-linearity nature of vocabulary growth (cf. Meara 1996 and the fundamental role played by frequency in word knowledge for vocabulary in general (Nation 1983, 1990, Nation and Beglar 2007, which are extended here to collocations knowledge.

    To evaluate the effects of hippotherapy on physical capacities of children with cerebral palsy. Thirteen children (4-12 years old) with cerebral palsy classified in Gross Motor Function Classification System Level I or II were included in this prospective quasi-experimental ABA design study. Participants received 10 weeks of hippotherapy (30 min per week). Gross motor function and proficiency were measured with the Bruininks-Oseretski Motor Proficiency short form [BOT2-SF]) and the Gross Motor Function Measure-88 [GMFM-88] (Dimension D and E) twice before the program (T1 and T1'), immediately after (T2), and 10 weeks following the end of the program (T3). Mean scores for dimensions D and E of the GMFM-88 Dimension scores (p = .005) and three out of the eight items of the BOT2-SF (fine motor precision (p = .013), balance (p = .025), and strength (p = .012) improved between baseline and immediately after intervention; mean scores immediately following and 10 weeks following intervention did not differ. Hippotherapy provided by a trained therapist who applies an intense and graded session for 10 weeks can improve body functions and performance of gross motor and fine motor activities in children with cerebral palsy.

    Full Text Available BACKGROUND Physical activity is the greatest contributor to achievement of adequate physical activity. Children performing adequate daily physical activity will get positive benefits from their activity. Several studies indicate a difference in motor skills between boys and girls. To understand the development of motor skill proficiency and physical activity in boys and girls, a study was conducted to determine the role of gender on motor skill proficiency and physical activity in children aged 6-12 years. METHODS A cross-sectional observational study was conducted and a total of 162 children were included at a primary school in the Grogol area, West Jakarta. Data collection was by questionnaire-based interviews, covering age, gender, and physical activity (watching TV, playing games, and outdoor play. Assessment of motor skills was performed using the Bruininks-Oseretsky Test–Second Edition (BOT-2. Data analysis was performed using SPSS for Windows release 17.0 and level of significance was set at 0.05. RESULTS Multiple linear regression results showed that in boys the strength subset was the most influential factor on TV watching activity, with the higher scores for strength indicating a lower TV watching activity (â=-0.125;p=0.021. Age was the most influential factor on outdoor playing activity in girls, with older girls having lower outdoor playing activity (â=-0.375;p=0.016. CONCLUSIONS This study revealed that gender difference impacts on motor skills and physical activity in children. Higher motor proficiency increases outdoor playing activity only in boys. Primary school pupils should be given opportunities for performing outdoor playing activities to improve their motor proficiency.

    To maintain and improve the efficiency and safety of operations in numerous industries, it is necessary to develop programs that enhance teamwork. This can be achieved through empirical investigations that identify influential factors contributing to teamwork. This study focused on technical skill proficiency and leadership as influential factors and examined the relationships among these factors and teamwork behaviors. A series of measurements was performed on 54 operations teams with the cooperation of the training center of thermal power plants. Teamwork behaviors in training under simulated abnormal conditions were evaluated through instructors' observation using a behavior checklist. Technical skill proficiency was measured by conducting a brief survey on instructors. Leadership was measured on the basis of followers' responses on questionnaire scales. Based on the scores of technical skill proficiency and leadership, hierarchical cluster analysis revealed three types of teams: (a) F-type - the technical skills of followers are superior to those of leaders; (b) LF-type - both leaders and followers are proficient in technical skills; and (c) L-type - the technical skills of leaders are superior to those of followers. ANOVAs were conducted to examine differences in teamwork behavior for the three types of teams. The main results revealed that LF-type teams actively engaged in information gathering and that leaders played a central role in these activities. In addition, the followers of F-type teams freely exchanged their ideas and opinions regarding problems and actively discussed how to solve them. These findings suggest that teamwork behaviors can vary depending on technical skill proficiency and leadership in teams. Future research is needed to identify additional factors affecting teamwork that are not measured in this study. (author)

There have been many linguistic studies trying to define, to describe, and to categorise English collocations. It contains grammatical collocations and lexical collocations which include nouns, adjectives, verbs, and adverb. In the context of a foreign language environment such as Iran, collocational proficiency can be useful because it helps the students improve their language proficiency. This paper investigates the possible relationship between verb-noun collocation proficiency among students from one academic year to the next. To reach this goal, a test of verb-noun collocations was administered to Iranian learners. The participants in the study were 212 Iranian students in an Iranian university. They were selected from the second term of freshman, sophomore, junior, and senior years. The students’ age ranged from 18 to 35.The results of ANOVA showed there was variability in the verb-noun collocations proficiency within each academic year and between the four academic years. The results of a post hoc multiple comparison tests demonstrated that the means are significantly different between the first year and the third and fourth years, and between the third and the fourth academic year; however, students require at least two years to show significant development in verb-noun collocation proficiency. These findings provided a vital implication that lexical collocations are learnt and developed through four academic years of university, but requires at least two years showing significant development in the language proficiency.

    The demonstration of competency in endoscopy is required prior to obtaining American Board of Surgery Certification. To demonstrate competency, the resident must pass a national high-stakes cognitive test and a technical skills exam on a virtual reality simulator. The purpose of this preliminary study was to design a proficiency-based endoscopy simulation curriculum to meet this competency requirement. This is a mixed methods prospective cohort study at a single academic medical institution. Prior to taking the national exam, surgery residents were required to participate in a skills lab and demonstrate proficiency on 10 simulation tasks. Proficiency was based on time and percent of objects targeted/mucosa seen. Simulation practice time, number of task repetitions to proficiency, and prior endoscopic experience were recorded. Resident's self-reported confidence scores in endoscopic skills prior to and following simulation lab training were obtained. From January 1, 2016 through August 1, 2017, 20 surgical residents (8 PGY2, 8 PGY3, 4 PGY4) completed both a faculty-supervised endoscopy skills lab and independent learning with train-to-proficiency simulation tasks. Median overall simulator time per resident was 306 min (IQR: 247-405 min). Median overall time to proficiency in all tasks was 235 min (IQR: 208-283 min). The median time to proficiency decreased with increasing PGY status (r = 0.4, P = 0.05). There was no correlation between prior real-time endoscopic experience and time to proficiency. Reported confidence in endoscopic skills increased significantly from mean of 5.75 prior to 7.30 following the faculty-supervised endoscopy skills lab (P = 0.0002). All 20 residents passed the national exam. In this preliminary study, a train-to-proficiency curriculum in endoscopy improved surgical resident's confidence in their endoscopic skills and 100% of residents passed the FES technical skills test on their first attempt. Our findings also indicate

  13. Performance on large-scale science tests: Item attributes that may impact achievement scores

    Significant differences in achievement among ethnic groups persist on the eighth-grade science Washington Assessment of Student Learning (WASL). The WASL measures academic performance in science using both scenario and stand-alone question types. Previous research suggests that presenting target items connected to an authentic context, like scenario question types, can increase science achievement scores especially in underrepresented groups and thus help to close the achievement gap. The purpose of this study was to identify significant differences in performance between gender and ethnic subgroups by question type on the 2005 eighth-grade science WASL. MANOVA and ANOVA were used to examine relationships between gender and ethnic subgroups as independent variables with achievement scores on scenario and stand-alone question types as dependent variables. MANOVA revealed no significant effects for gender, suggesting that the 2005 eighth-grade science WASL was gender neutral. However, there were significant effects for ethnicity. ANOVA revealed significant effects for ethnicity and ethnicity by gender interaction in both question types. Effect sizes were negligible for the ethnicity by gender interaction. Large effect sizes between ethnicities on scenario question types became moderate to small effect sizes on stand-alone question types. This indicates the score advantage the higher performing subgroups had over the lower performing subgroups was not as large on stand-alone question types compared to scenario question types. A further comparison examined performance on multiple-choice items only within both question types. Similar achievement patterns between ethnicities emerged; however, achievement patterns between genders changed in boys' favor. Scenario question types appeared to register differences between ethnic groups to a greater degree than stand-alone question types. These differences may be attributable to individual differences in cognition

    We evaluated the effectiveness of implementing a proficiency-driven, simulation-based knot tying and suturing curriculum for medical students during their 3rd-year surgery clerkship. Medical students on the 3rd-year surgical clerkship completed a proficiency-driven, simulation-based knot tying and suturing curriculum consisting of 6 tasks. The effectiveness was evaluated by comparing the initial presession scores to the final postsession scores on an 8-item self-efficacy scale and evaluating pass rates on end of clerkship skills testing. A paired t test was used to analyze data. Sixty-five students had matched preintervention and postintervention questionnaires for analysis. Pass rates approached 100% by the 3rd attempt on all tasks. Significant gains on all 8 items of the self-efficacy questionnaire from pretraining to post-training were noted. Timing of the general surgery rotation did not impact results. Implementation of a simulation-based training, proficiency-driven knot tying and suturing curriculum for 3rd-year medical students during the surgery clerkship is feasible and effective in improving student self-efficacy and objective proficiency toward performance of the tasks taught.

    Full Text Available Reviewing the literature on self-assessment as an alternative method of assessment we find advocates claiming for the accuracy of the students’ self-assessments in general with little focus on their level of proficiency. With an eye on the students’ level of reading proficiency, the present study aimed at investigating the relationship between students’ reading self-assessment (as a formative and alternative method of assessment on the one hand, and teacher assessment (as a formative type of assessment as well as students’ final examination scores (as a summative and traditional method of assessment on the other. To this end, 65 students of Islamic Azad University- Tehran South Branch were selected to participate in this study. Initially, participants received PET test as pretest for assigning them into different levels of reading proficiency. Based upon the results of the pretest, participants were assigned to elementary and intermediate levels. Throughout the whole semester self-assessment questionnaire was employed for five times. Descriptive statistics and Pearson correlation were the data analysis techniques performed. The results of the study revealed a significant relationship between the intermediate learners’ self-ratings and teacher assessments; however, the results indicated no significant relationship between elementary learners’ self-assessments and teacher assessments. Also, the correlations between students’ self-assessments and their final examination scores were not significant for both levels. Therefore, given the teacher assessment as the yardstick, the accuracy of the intermediate levels and the inaccuracy of the elementary learners’ self-assessments could be concluded. Finally, the low correlation between the learners’ self-assessments and their scores on traditional final examination led the researcher to attribute it to the different nature of these two assessment types.

    Introduction Pediatric brain tumor survivors are at risk for working memory and processing speed impairment. The General Ability Index (GAI) provides an estimate of intellectual functioning that is less influenced by working memory and processing speed than a Full Scale IQ (FSIQ). The Cognitive Proficiency Index (CPI) provides a measure of efficient information processing derived from working memory and processing speed tasks. We examined the utility of the GAI and CPI to quantify neurocognitive outcomes in a sample of pediatric brain tumor survivors. Methods GAI, CPI, and FSIQ scores from the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) were examined for 57 pediatric brain tumor survivors (ages 6–16) treated with cranial radiation therapy (RT). Results GAI scores were higher than FSIQ and CPI scores, both p < .001. Lower CPI scores were associated with history of craniospinal irradiation and time since RT. Lower FSIQ and GAI scores were associated with higher RT dose and time since RT. The rate of clinically significant GAI-FSIQ discrepancies in our sample was greater than observed in the WISC-IV standardization sample, p < .001. Estimated premorbid IQ scores were higher than GAI, p < .01, and FSIQ scores, p < .001. Conclusions Pediatric brain tumor survivors exhibit weaker cognitive proficiency than expected for age, while general reasoning ability remains relatively spared. The GAI may be useful to quantify the intellectual potential of a survivor when appropriate accommodations are in place for relative cognitive proficiency weaknesses. The CPI may be a particularly sensitive outcome measure of treatment-related cognitive change in this population. PMID:27295192

    2016-08-01

    In many countries around the world, there has been an increasing emphasis on improving science education. Recent reform efforts in the USA call for teachers to integrate scientific and engineering practices into science teaching; for example, science teachers are asked to provide learning experiences for students that apply crosscutting concepts (e.g., patterns, scale) and increase understanding of disciplinary core ideas (e.g., physical science, earth science). Engineering practices and engineering design are essential elements of this new vision of science teaching and learning. This paper presents a research study that evaluates the effects of an engineering design-based science curriculum on student learning and attitudes. Three middle school life science teachers and 275 seventh grade students participated in the study. Content assessments and attitude surveys were administered before and after the implementation of the curriculum unit. Statewide mathematics test proficiency scores were included in the data analysis as well. Results provide evidence of the positive effects of implementing the engineering design-based science unit on student attitudes and learning.

    This study examined whether students studying literature in complementary learning clusters would show more improvement in medical humanities literacy, critical thinking skills, and English proficiency compared to those in conventional learning clusters. Ninety-three students participated in the study (M age = 18.2 years, SD = 0.4; 36 men, 57 women). A quasi-experimental design was used over 16 weeks, with the control group (n = 47) working in conventional learning clusters and the experimental group (n = 46) working in complementary learning clusters. Complementary learning clusters were those in which individuals had complementary strengths enabling them to learn from and offer assistance to other cluster members, hypothetically facilitating the learning process. Measures included the Medical Humanities Literacy Scale, Critical Thinking Disposition Assessment, English proficiency tests, and Analytic Critical Thinking Scoring Rubric. The results showed that complementary learning clusters have the potential to improve students' medical humanities literacy, critical thinking skills, and English proficiency. © The Author(s) 2016.

    Narrative comprehension is a perinatal linguistic ability which is more intuitive than reading activity. Whether there are specific shared brain regions for narrative comprehension and reading that are tuned to reading proficiency, even before reading is acquired, is the question of the current study. We acquired fMRI data during a narrative comprehension task at two age points, when children are age 5-7 (K-2nd grade) and later when the same children were age 11 (5th-7th grade). We then examined correlations between this fMRI data and reading and reading comprehension scores from the same children at age 11. We found that greater frontal and supramarginal gyrus (BA 40) activation in narrative comprehension at the age of 5-7 years old was associated with better word reading and reading comprehension scores at the age of 11. A shift towards temporal and occipital activation was found when correlating their narrative comprehension functional data at age 11, with reading scores at the same age point. We suggest that increased reliance on executive functions and auditory-visual networks when listening to stories before reading is acquired, facilitates reading proficiency in older age and may be a biomarker for future reading ability. Children, who rely on use of imagination/visualization as well as auditory processing for narrative comprehension when they reach age 11, also show greater reading abilities. Understanding concordant neural pathways supporting auditory narrative and reading comprehension might be guide for development of effective tools for reading intervention programs.

    Standardized writing assessments such as the Minnesota Handwriting Assessment (MHA) can inform interventions for handwriting difficulties, which are prevalent among school-aged children. However, these tests usually involve the laborious task of subjectively rating the legibility of the written product, precluding their practical use in some clinical and educational settings. This study describes a portable computer-based handwriting assessment tool to objectively measure MHA quality scores and to detect handwriting difficulties in children. Several measures are proposed based on spatial, temporal, and grip force measurements obtained from a custom-built handwriting instrument. Thirty-five first and second grade students participated in the study, nine of whom exhibited handwriting difficulties. Students performed the MHA test and were subjectively scored based on speed and handwriting quality using five primitives: legibility, form, alignment, size, and space. Several spatial parameters are shown to correlate significantly (phandwriting legibility and speed, respectively. Using only size and space parameters, promising discrimination between proficient and non-proficient handwriting can be achieved. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    To assess the association of scores on the Health Sciences Reasoning Test (HSRT) with academic and experiential performance in a doctor of pharmacy (PharmD) curriculum. The HSRT was administered to 329 first-year (P1) PharmD students. Performance on the HSRT and its subscales was compared with academic performance in 29 courses throughout the curriculum and with performance in advanced pharmacy practice experiences (APPEs). Significant positive correlations were found between course grades in 8 courses and HSRT overall scores. All significant correlations were accounted for by pharmaceutical care laboratory courses, therapeutics courses, and a law and ethics course. There was a lack of moderate to strong correlation between HSRT scores and academic and experiential performance. The usefulness of the HSRT as a tool for predicting student success may be limited.

    Two air filters (V-50, P-50) artificially loaded with urban dust were provided from IAEA and trace elements to study inter-laboratory comparison and proficiency test were determined using instrumental neutron activation analysis non-destructively. Standard reference material(Urban Particulate Matter, NIST SRM 1648) of National Institute of Standard and Technology was used for internal analytical quality control. About 20 elements in each loaded filter sample were determined, respectively. Our analytical data were compared with statistical results using neutron activation analysis, particle induced X-ray emission spectrometry, inductively coupled plasma mass spectroscopy, etc., which were collected from 49 laboratories of 40 countries. From the results that were statistically re-treated with reported values, Z-scores of our analytical values are within ±2. In addition, the results of proficiency test are passed and accuracy and precision of the analytical values are reliable. Consequently, it was proved that analytical quality control for the analysis of air dust samples is reasonable

    Hepatobiliary surgery is a highly complex, low-volume specialty with long learning curves necessary to achieve optimal outcomes. This creates significant challenges in both training and measuring surgical proficiency. We hypothesize that a virtual reality curriculum with mastery-based simulation is a valid tool to train fellows toward operative proficiency. This study evaluates the content and predictive validity of robotic simulation curriculum as a first step toward developing a comprehensive, proficiency-based pathway. A mastery-based simulation curriculum was performed in a virtual reality environment. A pretest/posttest experimental design used both virtual reality and inanimate environments to evaluate improvement. Participants self-reported previous robotic experience and assessed the curriculum by rating modules based on difficulty and utility. This study was conducted at the University of Pittsburgh Medical Center (Pittsburgh, PA), a tertiary care academic teaching hospital. A total of 17 surgical oncology fellows enrolled in the curriculum, 16 (94%) completed. Of 16 fellows who completed the curriculum, 4 fellows (25%) achieved mastery on all 24 modules; on average, fellows mastered 86% of the modules. Following curriculum completion, individual test scores improved (p < 0.0001). An average of 2.4 attempts was necessary to master each module (range: 1-17). Median time spent completing the curriculum was 4.2 hours (range: 1.1-6.6). Total 8 (50%) fellows continued practicing modules beyond mastery. Survey results show that "needle driving" and "endowrist 2" modules were perceived as most difficult although "needle driving" modules were most useful. Overall, 15 (94%) fellows perceived improvement in robotic skills after completing the curriculum. In a cohort of board-certified general surgeons who are novices in robotic surgery, a mastery-based simulation curriculum demonstrated internal validity with overall score improvement.

    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.

    Work-hour restrictions and fatigue management strategies in surgical training programs continue to evolve in an effort to improve the learning environment and promote safer patient care. In response, training programs must reevaluate how various teaching modalities such as simulation can augment the development of surgical competence in trainees. For surgical simulators to be most useful, it is important to determine whether surgical proficiency can be reliably differentiated using them. To our knowledge, performance on both virtual and benchtop arthroscopy simulators has not been concurrently assessed in the same subjects. (1) Do global rating scales and procedure time differentiate arthroscopic expertise in virtual and benchtop knee models? (2) Can commercially available built-in motion analysis metrics differentiate arthroscopic expertise? (3) How well are performance measures on virtual and benchtop simulators correlated? (4) Are these metrics sensitive enough to differentiate by year of training? A cross-sectional study of 19 subjects (four medical students, 12 residents, and three staff) were recruited and divided into 11 novice arthroscopists (student to Postgraduate Year [PGY] 3) and eight proficient arthroscopists (PGY 4 to staff) who completed a diagnostic arthroscopy and loose-body retrieval in both virtual and benchtop knee models. Global rating scales (GRS), procedure times, and motion analysis metrics were used to evaluate performance. The proficient group scored higher on virtual (14 ± 6 [95% confidence interval {CI}, 10-18] versus 36 ± 5 [95% CI, 32-40], p virtual scope (579 ±169 [95% CI, 466-692] versus 358 ± 178 [95% CI, 210-507] seconds, p = 0.02) and benchtop knee scope + probe (480 ± 160 [95% CI, 373-588] versus 277 ± 64 [95% CI, 224-330] seconds, p = 0.002). The built-in motion analysis metrics also distinguished novices from proficient arthroscopists using the self-generated virtual loose body retrieval task scores (4 ± 1 [95% CI, 3

    This paper presents an experiment that investigated the effects of L2 proficiency and sentence constraint on semantic processing of unknown L2 words (pseudowords). All participants were Chinese native speakers who learned English as a second language. In the experiment, we used a whole sentence presentation paradigm with a delayed semantic relatedness judgment task. Both higher and lower-proficiency L2 learners could make use of the high-constraint sentence context to judge the meaning of novel pseudowords, and higher-proficiency L2 learners outperformed lower-proficiency L2 learners in all conditions. These results demonstrate that both L2 proficiency and sentence constraint affect subsequent word learning among second language learners. We extended L2 word learning into a sentence context, replicated the sentence constraint effects previously found among native speakers, and found proficiency effects in L2 word learning.

    We compared Hindi-English bilinguals differing in their L2 proficiency on a saccadic countermanding task which taps inhibitory control as well as monitoring. We particularly explored whether response inhibition and performance monitoring within the oculomotor domain are affected by language proficiency in bilinguals. There were two different oculomotor redirect tasks: Visually Guided Redirect (VGR) task (Experiment1) and Memory Guided Redirect (MGR) task (Experiment 2). In the redirect task, typically a target is presented and the subject is required to make a saccade (no-step trials), unless a new target appears on a different location after some delay from the first target onset (step trials). On such trials participants are required to inhibit and cancel the saccade to the first target and programme a saccade to the new target. Using trial switch reaction time (TSRT), the time taken to inhibit the initiated saccade to the first target as a measure of response inhibition and post-step slowing as a measure of performance monitoring. The results showed the high proficient bilinguals displayed more post-step slowing on the no-step trials as compared to the low proficient bilinguals for both VGR and MGR versions of the task. Secondly, both the high and low proficient bilinguals exhibited comparable TSRT in both VGR and MGR task, showing no modulatory effects of language proficiency on the response inhibition. These results suggest that language proficiency may have an effect on performance monitoring, but not the inhibitory control per se. Thus, we infer that higher proficiency may lead to superior cognitive flexibility and an ability to adjust behavior that facilitates the attainment of the cognitive goal. These findings are in consonance with other current studies that suggest a top-down effect of bilingualism on action control systems.

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

  19. Beyond English Proficiency: Rethinking Immigrant Integration

    Akresh, Ilana Redstone; Massey, Douglas S.; Frank, Reanne

    2014-01-01

    We develop and test a conceptual model of English language acquisition and the strength of the latter in predicting social and cultural assimilation. We present evidence that the path to English proficiency begins with exposure to English in the home country and on prior U.S. trips. English proficiency, then, has direct links to the intermediate migration outcomes of occupational status in the U.S., the amount of time in the U.S. since the most recent trip, and the co-ethnic residential context in the U.S. In turn, pre-migration characteristics and the intermediate characteristics work in tandem with English proficiency to determine social assimilation in the U.S., while cultural assimilation is primarily determined by pre-migration habits. A shift in focus to English use is desirable in studies of immigrant integration. PMID:24576636

    2013-01-01

    The proficiency tests are widely used to evaluate the analytical capacity of laboratories and also as part of the accreditation process. For this reason, are important tools for the control of the quality of the analytical results obtained in the laboratories that work directly with seafood companies. In Brazil there are no providers of proficiency testing for metals potentially toxic in fish tissues. In this work will be described all steps used for the production of reference materials to be used in a proficiency testing pilot study for As, Cd, Pb and Hg in fish tissue following the recommendations of the ISO Guide 35. He preparation scheme consisted in selecting the individuals, cleaning, grinding, homogenization and fortification with As, Cd and Pb in two concentration levels. The preparation resulted in 164 sachets of 10 g each. In order to evaluate the effect of gamma irradiation in the samples conservation 52 sachets were irradiated with 60 Co (10.00 ± 1.05 kGy) in a gamma cell. This material with others non irradiated 52 sachets were used for the homogeneity and stability studies. The remaining 60 were used for the proficiency testing. The results demonstrated that both materials were homogeneous and presented good stability (during a period of 45 days). However, the irradiated material present better integrity, concerning biological degradation, when stored in ambient temperature. For this reason they were used to the proficiency testing pilot program. Ten laboratories participated in the proficiency testing pilot study and the results were evaluated using the following tests: z-score, confidence ellipse and En numbers. This work demonstrates the capability of the laboratory to produce reference materials as well as to organize and conduct proficiency testing. (author)

  2. A Case for Improved Reading Instruction for Academic English Reading Proficiency

    Full Text Available This article presents a study of the academic reading proficiency in English of 217 senior level Norwegian upper secondary school students who upon graduation are considered qualified for higher education. Testing with an International English Language Testing System (IELTS Academic Reading Module revealed that two thirds of the 178 respondents with ordinary EFL courses did not achieve the equivalent of the IELTS Band 6 score minimum that is usually required for admission to British and Australian universities. In comparison, two thirds of a sample of 39 respondents with a single, sheltered Content and Language Integrated Learning (CLIL subject achieved a Band 6 score or better. Closer analysis indicates that the poor test scores can be attributed to weaknesses in current English as a Foreign Language (EFL instruction where reading is neglected, where students do not learn to adjust how they read to reading purpose, and where they do not learn how to handle unfamiliar words to avoid disrupting the reading process. The article ends with suggestions on how to improve EFL instruction, in Norway and elsewhere.

    Full Text Available Recently a number of quasi-experimental studies have investigated the potential of a cross-modality transfer of second language competency between real-time, conversational exchange via text and speech (Abrams, 2003; Beauvious, 1998; Kost, 2004; Payne & Whitney, 2002. Payne and Whitney employed Levelt's (1989 model of language production and concepts from working memory as a rationale for a hypothesized connection between synchronous computer-mediated communication (SCMC and second language (L2 speech and as a basis for predicting the differential contributions of SCMC to the L2 oral proficiency development.This study extends the psycholinguistic framework reported in Payne and Whitney (2002 with discourse and corpus analytic techniques to explore how individual differences in working memory capacity may affect the frequency of repetition and other patterns of language use in chatroom discourse. Working memory capacity was measured by a reading span and nonword repetition test. Oral proficiency was measured with a speaking task that solicited a 5-minute speech sample and was scored based on a holistic scale. The data collected from 20 chat sessions were analyzed for occurrences of repetition and relexicalization, as well as language output measures. Findings suggest a connection between working memory and language output as measured in this study.

    Wood, Lara A; Kendal, Rachel L; Flynn, Emma G

    2015-11-01

    The current study investigated whether 4- to 6-year-old children's task solution choice was influenced by the past proficiency of familiar peer models and the children's personal prior task experience. Peer past proficiency was established through behavioral assessments of interactions with novel tasks alongside peer and teacher predictions of each child's proficiency. Based on these assessments, one peer model with high past proficiency and one age-, sex-, dominance-, and popularity-matched peer model with lower past proficiency were trained to remove a capsule using alternative solutions from a three-solution artificial fruit task. Video demonstrations of the models were shown to children after they had either a personal successful interaction or no interaction with the task. In general, there was not a strong bias toward the high past-proficiency model, perhaps due to a motivation to acquire multiple methods and the salience of other transmission biases. However, there was some evidence of a model-based past-proficiency bias; when the high past-proficiency peer matched the participants' original solution, there was increased use of that solution, whereas if the high past-proficiency peer demonstrated an alternative solution, there was increased use of the alternative social solution and novel solutions. Thus, model proficiency influenced innovation. Copyright © 2015 Elsevier Inc. All rights reserved.

    2018-04-17

    Performance on the Mini-Mental State Examination (MMSE), among the most widely used global screens of adult cognitive status, is affected by demographic variables including age, education, and ethnicity. This study extends prior research by examining the specific effects of bilingualism on MMSE performance. Sixty independent community-dwelling monolingual and bilingual adults were recruited from eastern and western regions of the United States in this cross-sectional group study. Independent sample t tests were used to compare 2 bilingual groups (Spanish-English and Asian Indian-English) with matched monolingual speakers on the MMSE, demographically adjusted MMSE scores, MMSE item scores, and a nonverbal cognitive measure. Regression analyses were also performed to determine whether language proficiency predicted MMSE performance in both groups of bilingual speakers. Group differences were evident on the MMSE, on demographically adjusted MMSE scores, and on a small subset of individual MMSE items. Scores on a standardized screen of language proficiency predicted a significant proportion of the variance in the MMSE scores of both bilingual groups. Bilingual speakers demonstrated distinct performance profiles on the MMSE. Results suggest that supplementing the MMSE with a language screen, administering a nonverbal measure, and/or evaluating item-based patterns of performance may assist with test interpretation for this population.

    Full Text Available The aim of this study was to evaluate the utility of a proficiency testing program among limited number of local laboratories as an alternative to the IUPAC/CITAC guide on proficiency testing with a limited number of participants, specially where international schemes are not accessible. As a sample scheme we planned to determine aflatoxins (B1, G1, B2, G2, total in Iranian pistachio matrix. A part of naturally contaminated pistachio sample was tested for sufficient homogeneity by a competent laboratory and then homogenized sub-samples were distributed among participants all across the country. The median of participants’ results was selected as assigned value. Student t-test was applied to show there is no significant difference between assigned and mean values of homogeneity test results obtained by the competent laboratory. Calculated z-scores showed that 6 out of 8 results in aflatoxin B1, 7 out of 8 results in aflatoxin B2, 5 out of 8 results in aflatoxin G1, 7 out of 8 results in aflatoxin G2 and 6 out of 9 results in aflatoxin total were in satisfactory range. Together our studies indicate that the approach described here is highly cost efficient and applicable for quality assurance of test results when there is no access to international proficiency testing providers.

    Lichon, Kathryn A.

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

    2004-01-01

    The written English vocabulary of 72 deaf elementary school students of various proficiency levels in American Sign Language (ASL) was compared with the performance of 60 hearing English-as-a-second-language (ESL) speakers and 61 hearing monolingual speakers of English, all of similar age. Students were asked to retell "The Tortoise and the Hare" story (previously viewed on video) in a writing activity. Writing samples were later scored for total number of words, use of words known to be highly frequent in children's writing, redundancy in writing, and use of English function words. All deaf writers showed significantly lower use of function words as compared to their hearing peers. Low-ASL-proficient students demonstrated a highly formulaic writing style, drawing mostly on high-frequency words and repetitive use of a limited range of function words. The moderate- and high-ASL-proficient deaf students' writing was not formulaic and incorporated novel, low-frequency vocabulary to communicate their thoughts. The moderate- and high-ASL students' performance revealed a departure from findings one might expect based on previous studies with deaf writers and their vocabulary use. The writing of the deaf writers also differed from the writing of hearing ESL speakers. Implications for deaf education and literacy instruction are discussed, with special attention to the fact that ASL-proficient, deaf second-language learners of English may be approaching English vocabulary acquisition in ways that are different from hearing ESL learners.

    2017-10-17

    This study assessed home and community language proficiency in Spanish-English bilingual university students to investigate whether the vocabulary gap reported in studies of bilingual children persists into adulthood. Sixty-five early bilinguals (mean age = 21 years) were assessed in English and Spanish vocabulary and verbal reasoning ability using subtests of the Woodcock-Muñoz Language Survey-Revised (Schrank & Woodcock, 2009). Their English scores were compared to 74 monolinguals matched in age and level of education. Participants also completed a background questionnaire. Bilinguals scored below the monolingual control group on both subtests, and the difference was larger for vocabulary compared to verbal reasoning. However, bilinguals were close to the population mean for verbal reasoning. Spanish scores were on average lower than English scores, but participants differed widely in their degree of balance. Participants with an earlier age of acquisition of English and more current exposure to English tended to be more dominant in English. Vocabulary tests in the home or community language may underestimate bilingual university students' true verbal ability and should be interpreted with caution in high-stakes situations. Verbal reasoning ability may be more indicative of a bilingual's verbal ability.

    This study of deaf college students examined specific relationships between their mathematics performance and their assessed skills in reading, language, and English morphology. Simple regression analyses showed that deaf college students' language proficiency scores, reading grade level, and morphological knowledge regarding word segmentation and meaning were all significantly correlated with both the ACT Mathematics Subtest and National Technical Institute for the Deaf (NTID) Mathematics Placement Test scores. Multiple regression analyses identified the best combination from among these potential independent predictors of students' performance on both the ACT and NTID mathematics tests. Additionally, the participating deaf students' grades in their college mathematics courses were significantly and positively associated with their reading grade level and their knowledge of morphological components of words.

    2009-03-01

    Cross-sectional evidence has demonstrated the importance of motor skill proficiency to physical activity participation, but it is unknown whether skill proficiency predicts subsequent physical activity. In 2000, children's proficiency in object control (kick, catch, throw) and locomotor (hop, side gallop, vertical jump) skills were assessed in a school intervention. In 2006/07, the physical activity of former participants was assessed using the Australian Physical Activity Recall Questionnaire. Linear regressions examined relationships between the reported time adolescents spent participating in moderate-to-vigorous or organized physical activity and their childhood skill proficiency, controlling for gender and school grade. A logistic regression examined the probability of participating in vigorous activity. Of 481 original participants located, 297 (62%) consented and 276 (57%) were surveyed. All were in secondary school with females comprising 52% (144). Adolescent time in moderate-to-vigorous and organized activity was positively associated with childhood object control proficiency. Respective models accounted for 12.7% (p = .001), and 18.2% of the variation (p = .003). Object control proficient children became adolescents with a 10% to 20% higher chance of vigorous activity participation. Object control proficient children were more likely to become active adolescents. Motor skill development should be a key strategy in childhood interventions aiming to promote long-term physical activity.

    Despite decades of research on fundamental memory strategies such as verbal rehearsal, the potential underlying skills associated with the emergence of rehearsal are still not fully understood. Two studies examined the relative roles of language proficiency and metamemory in predicting rehearsal use, as well as the prediction of metamemory performance by language proficiency. In Study 1, 59 children, 5 to 8 years old, were administered a serial recall task, 2 language measures, a nonverbal cognitive measure, and a rapid automatized naming (RAN) task. Language proficiency, RAN, and age were significant individual predictors of rehearsal use. In hierarchical regression analyses, language proficiency mediated almost completely the age → rehearsal use relation. In addition, automatized naming was a strong but partial mediator of the contribution of language proficiency to rehearsal use. In Study 2, 54 children were administered a metamemory test, a language measure, and a serial recall task. Metamemory skills and, again, language proficiency significantly predicted rehearsal use in the task. The predictive strength of metamemory skills was mediated by the children's language proficiency. The mutually supportive roles of automatized naming, language, and metamemory in the emergence of spontaneous cumulative verbal rehearsal are discussed in the context of the resulting model, along with the minimal roles of age and aspects of intelligence.

    Full Text Available Background and Purpose: Some professors and educators in the field of English language believe that the high grades attained by medical students in their Comprehensive Medical Basic Sciences Exam (CMBSE are mainly a result of the students prior fluency in the language before entering medical colleges; they are of the opinion that these grades are not necessarily a result of the combined effort of the English teachers and students in language courses at the university. This research aimsat determining the correlation between the level of fluency in English of medical students prior to university entrance and the grades obtained by them in their CMBSE after 3 terms of language courses at the university.Methods: Seven of the major and smaller universities of medical sciences were selected. The language scores of 2426 students admitted to these universities during the three academic years of 1999 to 2002 in both the National University Entrance Examination (NUEE and the Comprehensive Medical Basic Sciences Exam (CMBSE were obtained from their related universities and from the secretariat of the Council of Medical Basic Sciences Education respectively. The language scores of each studentobtained in both NUEE and CMBSE were then matched. The related SPSS software was used to assess the level of correlation between these two groups of language scores for the students of each university, for each academic year and semester and also the overall score for the three years.Results: Overall a positive and moderately significant correlation was found between the NUEE language scores and those of the CMBSE of the students of the universities studied (P<0/001; R=443%. The level of correlation for the various universities studied differed (Max. 69%, min.27%.A comparison of the means of these two groups of scores also confirmed this correlation.Conclusion: students’ grades The NUEE language score was not the only factor affecting the student’s CMBSE score

    Wu, Jason S.

    Improving outcomes for English language learners (ELLs) in secondary science remains an area of high need. The purpose of this study is to investigate bilingual knowledge organization in secondary science classrooms. This study involved thirty-nine bilingual students in three biology classes at a public high school in The Bronx, New York City. Methods included an in-class survey on language use, a science content and English proficiency exam, and bilingual free-recalls. Fourteen students participated in bilingual free-recalls which involved a semi-structured process of oral recall of information learned in science class. Free-recall was conducted in both English and Spanish and analyzed using flow-map methods. Novel methods were developed to quantify and visualize the elaboration and mobilization of ideas shared across languages. It was found that bilingual narratives displayed similar levels of organizational complexity across languages, though English recalls tended to be longer. English proficiency was correlated with narrative complexity in English. There was a high degree of elaboration on concepts shared across languages. Finally, higher Spanish proficiency correlated well with greater overlapping elaboration across languages. These findings are discussed in light of current cognitive theory before presenting the study's limitations and future directions of research.

    2004-01-01

    National factor(s) influencing publication output in the highest ranked medical journals are largely unknown. We sought to examine the relationship between national research funding and English proficiency on publication output. We identified all original research articles appearing in the five highest ranked general medical journals between 1997 and 2001. Using the country of the corresponding author as the source nation for each article, we determined a standardized publication rate across developed nations. We used multiple regression techniques to determine the influence of national expenditures on research and scores from the Test of English as a Foreign Language (TOEFL), a surrogate for English proficiency, on publication output. There was a significant relationship of national spending on research and TOEFL scores to publication output of developed countries (p = 0.04; p < 0.01, respectively). These two variables explained approximately 71.5% of the variation in publication rate across developed nations around the world (R = 0.85; p < 0.01). Normalized for population size, English-speaking nations and certain northern European countries such as Denmark, The Netherlands, Switzerland, and Sweden had the highest rate of publication in the five highest ranked general medical journals, while Asian countries had generally low rates of publication. Research spending and English proficiency were strongly associated with publication output in the highest ranked general medical journals. While these data cannot be considered definitive due to their observational nature, they do suggest that for English-language medical journals, research funding and English proficiency may be important determinants of publication.

    Full Text Available The objectives of the present study are four-fold: (1 to identify the types of strategies to maintain proficiency used by teachers of English in Indonesia, (2 to know the intensity of use of the obtained strategy types, (3 to measure the inter-correlation in the use of the obtained strategy types, and (4 to investigate the effect of proficiency level on the use of maintaining strategies. The subjects were 93 teachers applying for S2 degree in 2010/2011 at the postgraduate program of the Islamic University of Malang. They were given two sets of instrument, a Likert-scale questionnaire of English proficiency maintaining strategies and a TOEFL test. Then, a factor analysis identified nine strategy categories, including language focusing, metacognitive and affective developing, reading and writing activating, language resource utilizing, cognitive processing, culture learning, social communicating, text analyzing, and radio listening strategies. These strategy types explained 63.84% of variances of maintaining strategies and they were used at high level of intensity. Moreover, the use of the nine strategy types were found to be inter-correlated with one another. Finally, no significant effect of proficiency level on strategy use was found, indicating that teachers with different level of proficiency reported using the same strategies of maintaining their proficiency.

    This paper uses data from the Program for the International Assessment of Adult Competencies (PIAAC) to analyze the relationship between self-reported health (SRH) and literacy and numeracy proficiency for immigrants compared to U.S.-born respondents and for Hispanic versus Asian immigrants. The research questions were: (1) Are literacy and numeracy scores associated with adults' SRH? (2) Are associations between SRH and literacy and numeracy proficiency moderated by immigrant status? (3) Among immigrants, are literacy and numeracy scores more strongly associated with SRH for Hispanics versus Asians? Immigrants had significantly lower literacy and numeracy scores, yet reported better health than U.S.-born respondents. Ordinal logistic regression analyses showed that literacy and numeracy were both positively related to SRH for immigrants and U.S.-born adults, and should therefore be viewed as part of the growing evidence that literacy is an independent and significant social determinant of health. Second, U.S.-born and immigrant adults accrued similarly positive health benefits from stronger literacy and numeracy skills. Third, although Hispanic immigrants were more disadvantaged than Asian immigrants on almost all socioeconomic characteristics and had significantly lower literacy and numeracy scores and worse SRH than Asian immigrants, both Hispanic and Asian immigrants experienced similar positive health returns from literacy and numeracy proficiency. These findings underscore the potential health benefits of providing adult basic education instruction, particularly for immigrants with the least formal schooling and fewest socioeconomic resources.

    Although we know that family involvement is associated with stronger math performance, little is known about what educators are doing to effectively involve families and community members, and whether this measurably improves math achievement at their schools. This study used data from 39 schools to assess the effects of family and community involvement activities on school levels of math achievement. The study found that better implementation of math-related practices of family and community involvement predicted stronger support from parents for schools’ partnership programs, which, in turn, helped estimate the percentage of students scoring proficient on math achievement tests.

    The authors documented California's tobacco control initiatives for Asian Americans and the current tobacco use status among Asian subgroups and provide a discussion of the challenges ahead. The California Tobacco Control Program has employed a comprehensive approach to decrease tobacco use in Asian Americans, including ethnic-specific media campaigns, culturally competent interventions, and technical assistance and training networks. Surveillance of tobacco use among Asian Americans and the interpretation of the results have always been a challenge. Data from the 2001 The California Health Interview Survey (CHIS) were analyzed to provide smoking prevalence estimates for all Asian Americans and Asian-American subgroups, including Korean, Filipino, Japanese, South Asian, Chinese, and Vietnamese. Current smoking prevalence was analyzed by gender and by English proficiency level. Cigarette smoking prevalence among Asian males in general was almost three times of that among Asian females. Korean and Vietnamese males had higher cigarette smoking prevalence rates than males in other subgroups. Although Asian females in general had low smoking prevalence rates, significant differences were found among Asian subgroups, from 1.1% (Vietnamese) to 12.7% (Japanese). Asian men who had high English proficiency were less likely to be smokers than men with lower English proficiency. Asian women with high English proficiency were more likely to be smokers than women with lower English proficiency. Smoking prevalence rates among Asian Americans in California differed significantly on the basis of ethnicity, gender, and English proficiency. English proficiency seemed to have the effect of reducing smoking prevalence rates among Asian males but had just the opposite effect among Asian females. Cancer 2005.

    Fifty-four students were tested at specific time intervals over 10 years to determine best native language (NL) predictors of oral and written foreign language (FL) proficiency and FL aptitude. All participants completed two years of Spanish, French, or German. Each was administered measures of NL literacy, oral language, and cognitive ability in elementary school. A measure of FL aptitude was administered at the beginning of ninth grade and FL proficiency was evaluated at the end of the 10th grade. Among the variables, NL literacy measures were the best predictors of FL proficiency, and NL achievement and general (verbal) intelligence were strong predictors of FL aptitude. Results suggest that indices of NL literacy as early as first grade are related to FL proficiency and FL aptitude nine and 10 years later. Findings provide strong support for connections between L1 and L2 skills, and for speculation that "lower level" skills in phonological processing are important for written language development and oral proficiency in a FL.

    The College of American Pathologists surveys are the largest laboratory peer comparison programs in the world. These programs allow laboratories to regularly evaluate their performance and improve the accuracy of the patient test results they provide. Proficiency testing is offered twice a year to laboratories performing microsatellite instability testing. These surveys are designed to emulate clinical practice, and some surveys have more challenging cases to encourage the refinement of laboratory practices. This report summarizes the results and trends in microsatellite instability proficiency testing from participating laboratories from the inception of the program in 2005 through 2012. We compiled and analyzed data for 16 surveys of microsatellite instability proficiency testing during 2005 to 2012. The number of laboratories participating in the microsatellite instability survey has more than doubled from 42 to 104 during the 8 years analyzed. An average of 95.4% of the laboratories correctly classified each of the survey test samples from the 2005A through 2012B proficiency challenges. In the 2011B survey, a lower percentage of laboratories (78.4%) correctly classified the specimen, possibly because of overlooking subtle changes of microsatellite instability and/or failing to enrich the tumor content of the specimen to meet the limit of detection of their assay. In general, laboratories performed well in microsatellite instability testing. This testing will continue to be important in screening patients with colorectal and other cancers for Lynch syndrome and guiding the management of patients with sporadic colorectal cancer.

    Full Text Available Computers have taken an important place in the training of science students and in the professional life of scientists. It is often taken for granted that most students have mastered basic Information and Communication Technologies (ICT skills; however, it has been shown that not all students are equally proficient in this regard. Starting from theories of socialization and technology acceptance we report how we constructed a structural equation model (SEM to explore the variance in the basic ICT skill levels of science students. We also present the results of a test of this model with university bachelor’s science students. Basic ICT skills were measured using a new, elaborate instrument allowing students to rate their skills in detail. Our results show that science students score high on basic ICT skills and that our SEM explains a large part of the variation in the ICT skill levels of these students. The most explanatory power is coming from four variables: the perceived ease of use and the perceived usefulness of a personal computer, the anxiety for using a personal computer, and students’ belief that ICT is necessary for scientific research.

    Hilosky, Alexandra Borzillo

    American students are not developing the science inquiry skills needed to solve complex 21st century problems, thus impacting the workforce. In 2009, American high school students ranked 21 out of 26 in the category of problem-solving according to the Program for International Student Assessment. Serious video games have powerful epistemic value and are beneficial with respect to enhancing inquiry, effective problem-solving. The purpose of this correlational, quantitative study was to test Gee's assumption regarding the cycle of thinking (routinization, automatization, and deroutinization) by determining whether players status was a significant predictor of science inquiry scores, controlling for age, gender, and major. The 156 non-random volunteers who participated in this study were enrolled in a 2-year college in the northeastern U.S. Multiple regression analyses revealed that major was the strongest overall (significant) predictor, b = -.84, t(149) = -3.70, p video game play. Recommendations include using serious games as instructional tools and to assess student learning (formative and summative), especially among non-traditional learners.

    The recent Ebola virus disease outbreak emphasized the potential misuse of personal protective equipment (PPE) by health care workers (HCWs) during such an event. We aimed to compare self-perceived proficiency of PPE use and objective performance, and identify predictors of low compliance and PPE misuse. An observational study combined with subjective questionnaires were carried out during a bioterror simulation drill. Forty-two observers evaluated performance under PPE. Mistakes were recorded and graded using a structured observational format and were correlated with the subjective questionnaires and with demographic parameters. One hundred seventy-eight HCWs from community clinics and hospitals were included. The mean self-perceived proficiency was high (6.1 out of 7), mean level of comfort was moderate (4.0 out of 7), and mean objective performance was intermediate (9.5 out of 13). There was no correlation between comfort and objective performance scores. Self-perceived proficiency was in correlation with donning and continuous performance with PPE but not with doffing. Clinic personnel performed better than personnel in hospitals (40.3% vs 67.8% with 3 or more mistakes, respectively; P = .001). Demographic characteristics had no correlation with objective or self-perceived performance. Self-perceived proficiency is a poor predictor of appropriate PPE use. The results suggest poor awareness of the possibility of PPE misuse. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

    How MESSENGER Meshes Simulations and Games with Citizen Science In the film The Last Starfighter, an alien civilization grooms their future champion—a kid on Earth—using a video game. As he gains proficiency in the game, he masters the skills he needs to pilot a starship and save their civilization. The NASA MESSENGER Education and Public Outreach (EPO) Team is using the same tactic to train citizen scientists to help the Science Team explore the planet Mercury. We are building a new series of games that appear to be designed primarily for fun, but that guide players through a knowledge and skill set that they will need for future science missions in support of MESSENGER mission scientists. As players score points, they gain expertise. Once they achieve a sufficiently high score, they will be invited to become participants in Mercury Zoo, a new program being designed by Zooniverse. Zooniverse created Galaxy Zoo and Moon Zoo, programs that allow interested citizens to participate in the exploration and interpretation of galaxy and lunar data. Scientists use the citizen interpretations to further refine their exploration of the same data, thereby narrowing their focus and saving precious time. Mercury Zoo will be designed with input from the MESSENGER Science Team. This project will not only support the MESSENGER mission, but it will also add to the growing cadre of informed members of the public available to help with other citizen science projects—building on the concept that engaged, informed citizens can help scientists make new discoveries. The MESSENGER EPO Team comprises individuals from the American Association for the Advancement of Science (AAAS); Carnegie Academy for Science Education (CASE); Center for Educational Resources (CERES) at Montana State University (MSU) - Bozeman; National Center for Earth and Space Science Education (NCESSE); Johns Hopkins University Applied Physics Laboratory (JHU/APL); National Air and Space Museum (NASM); Science

    An experimental proficiency test program for ability to screen 104 residual pesticides in agricultural products has been conducted. Eight Japanese laboratories joined the program. Items tested in the present study were limit of detection, internal proficiency test (self spike) and external proficiency test (blind spike). All 104 pesticides were well detected and recovered from agricultural foods in the internal proficiency test. However, the results of the external proficiency test did not completely agree with those of the internal proficiency tests. After 5 rounds of the blind spike test, the ratio of the number of correctly detected pesticides to that of actually contained ones (49 total) ranged from 65% to 100% among laboratories. The numbers of mistakenly detected pesticides by a laboratory were 0 to 15. Thus, there was a great difference among the laboratories in the ability to screen multiresidual pesticides.

    Bowers, Sharon W.

    The purpose of this study was to explore the McDaniel College Elementary STEM Instructional Leader (ESIL) pilot cohort's ability to proficiently plan lessons that incorporated the Maryland State STEM Standards of Practice (SOP), targeting integration of STEM content, inquiry learning, students' abilities to collaborate as a STEM team and students' strategic application of technology. Data collection, in the form of reviewing and analyzing study participants' lesson plans and self-reflections, was completed by three independent assessors. The researcher examined the interrater reliability among the three assessors using the Fleiss' kappa statistic. A 0.91 proportion of agreement consensus was documented among the three assessors. A test of hypothetical value was conducted using the nonparametric Wilcoxonsigned- rank Test. Interpretation of the Wilcoxon-signed-rank Test results suggest that the sample population demonstrated proficient planning abilities for the four targeted Maryland State STEM SOP. Findings from this research add to the field's knowledge of elements in the promotion of graduate coursework that leads to elementary in-service teachers' proficiency in planning STEM-centric lessons, however the findings also have broader implications for teacher education at large. The McDaniel College ESIL model could frame K-12 teacher education for both preservice and in-service teachers. The pragmatic, hybrid experience maximizes flexibility, promotes analytical thinking and self-reflection and builds communication skills. The introduction and development of inquiry and design-based learning through the 7E Learning Cycle develops the teachers' understanding of practices promoted not only within the Maryland State STEM SOP, but also within the Next Generation Science Standards. The McDaniel College ESIL model also builds upon the collective efforts of academia, a non-profit STEM research facility, and local school divisions to align efforts that may lead to

    Purpose: Mismatch repair (MMR) proficiency has been reported to either increase or decrease radioenhancement by 24-h incubations with gemcitabine. This study aimed to establish the importance of MMR for radioenhancement by gemcitabine after short-exposure, high-dose treatment and long-exposure, low-dose treatment. Methods and Materials: Survival of MMR-deficient HCT116 and MMR-proficient HCT116 + 3 cells was analyzed by clonogenic assays. Mild, equitoxic gemcitabine treatments (4 h, 0.1 μM vs. 24 h, 6 nM) were combined with γ-irradiation to determine the radioenhancement with or without recovery. Gemcitabine metabolism and cell-cycle effects were evaluated by high-performance liquid chromatography analysis and bivariate flow cytometry. Results: Radioenhancement after 4 h of 0.1 μM of gemcitabine was similar in both cell lines, but the radioenhancement after 24 h of 6 nM of gemcitabine was reduced in MMR-proficient cells. No significant differences between both cell lines were observed in the gemcitabine metabolism or cell-cycle effects after these treatments. Gemcitabine radioenhancement after recovery was also lower in MMR-proficient cells than in MMR-deficient cells. Conclusion: Mismatch repair proficiency decreases radioenhancement by long incubations of gemcitabine but does not affect radioenhancement by short exposures to a clinically relevant gemcitabine dose. Our data suggest that MMR contributes to the recovery from gemcitabine treatment

    2015-08-01

    A huge gap in science literacy is between students who do not show the competencies that are necessary to participate effectively in life situations related to science and technology and students who have the skills which would give them the potential to create new technology. The objective of this paper is to identify, for 25 countries, distinct subgroups of students with characteristics that appear to be associated with this proficiency gap. Data were based on the answers of 46,131 PISA 2006 students with scores classified below level 2 or above level 4, as well as the answers of their principals to school questionnaire and the OECD indicators of the financial and human resources invested in education at the national level for secondary school. The dependent variable of the analysis was a dichotomous variable the values of which represent the two different groups of students. The independent variables were the OECD indicators, and the items and indices derived from the student and school questionnaires. The analysis was based on classification trees and the findings were replicated and extended by the means of a multilevel logistic regression model. The results show that very specific levels of teachers' salaries, parental pressure on schools, school size, awareness of environmental issues, science self-efficacy and socio-economic status have a very important role in predicting whether 15 year olds in OECD countries will belong to the lower or the highest proficiency groups as regards their aptitude in the context of life situations involving problems of a scientific nature.

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

    ISO/TC 212 covering clinical laboratory testing and in vitro diagnostic test systems will issue the international standard for medical laboratory quality and competence requirements, ISO 15189. This standard is based on the ISO/IEC 17025, general requirements for competence of testing and calibration laboratories and ISO 9001, quality management systems-requirements. Clinical laboratory services are essential to patient care and therefore should be available to meet the needs of all patients and clinical personnel responsible for human health care. If a laboratory seeks accreditation, it should select an accreditation body that operates according to this international standard and in a manner which takes into account the particular requirements of clinical laboratories. Proficiency testing should be available to evaluate the calibration laboratories and reference measurement laboratories in clinical medicine. Reference measurement procedures should be of precise and the analytical principle of measurement applied should ensure reliability. We should be prepared to establish a quality management system and proficiency testing in clinical laboratories.

    Little is known about the impacts of health literacy and English proficiency on the health status of Somali refugees. Data came from interviews in 2009-2011 of 411 adult Somali refugees recently resettled in Massachusetts. English proficiency, health literacy, and physical and mental health were measured using the Basic English Skills Test Plus, the Short Test of Health Literacy in Adults, and the Physical and Mental Component Summaries of the Short Form-12. Associations were analyzed using multiple linear regression. In adjusted analyses, higher English proficiency was associated with worse mental health in males. English proficiency was not associated with physical health. Health literacy was associated with neither physical nor mental health. Language proficiency may adversely affect the mental health of male Somali refugees, contrary to findings in other immigrant groups. Research on underlying mechanisms and opportunities to understand this relationship are needed.

  9. The effects of blogs versus dialogue journals on open-response writing scores and attitudes of grade eight science students

    Science.gov (United States)

    Erickson, Diane K.

    Today's students have grown up surrounded by technology. They use cell phones, word processors, and the Internet with ease, talking with peers in their community and around the world through e-mails, chatrooms, instant messaging, online discussions, and weblogs ("blogs"). In the midst of this technological explosion, adolescents face a growing need for strong literacy skills in all subject areas for achievement in school and on mandated state and national high stakes tests. The purpose of this study was to examine the use of blogs as a tool for improving open-response writing in the secondary science classroom in comparison to the use of handwritten dialogue journals. The study used a mixed-method approach, gathering both quantitative and qualitative data from 94 students in four eighth-grade science classes. Two classes participated in online class blogs where they posted ideas about science and responded to the ideas of other classmates. Two classes participated in handwritten dialogue journals, writing ideas about science and exchanging journals to respond to the ideas of classmates. The study explored these research questions: Does the use of blogs, as compared to the use of handwritten dialogue journals, improve the open-response writing scores of eighth grade science students? How do students describe their experience using blogs to study science as compared to students using handwritten dialogue journals? and How do motivation, self-efficacy, and community manifest themselves in students who use blogs as compared to students who use handwritten dialogue journals? The quantitative aspect of the study used data from pre- and post-tests and from a Likert-scale post-survey. The pre- and post-writing on open-response science questions were scored using the Massachusetts Comprehensive Assessment System (MCAS) open-response scoring rubric. The study found no statistically significant difference in the writing scores between the blog group and the dialogue journal

    Following long-duration space travel, pressurized rovers will enhance crew mobility to explore Mars and other planetary surfaces. Adaptive changes in sensorimotor function may limit the crew s proficiency when performing some rover operations shortly after transition to the new gravitoinertial environment. The primary goal of this investigation is to quantify postflight decrements in operational proficiency in a motion-based rover simulation after International Space Station (ISS) expeditions. Given that postflight performance will also be influenced by the level of preflight proficiency attained, a ground-based normative study was conducted to characterize the acquisition of skills over multiple sessions.

  12. Maintenance proficiency evaluation test bank

    The Maintenance Proficiency Evaluation Test Bank (MPETB) is an Electric Power Research Institute- (EPRJ-) operated, utility-sponsored means of developing, maintaining, and disseminating secure, high-quality written and performance maintenance proficiency tests. EPRTs charter is to ensure that all tests and test items that go into the Test Bank have been validated, screened for reliability, and evaluated to high standards of psychometric excellence. Proficiency tests of maintenance personnel.(mechanics, electricians, and instrumentation and control [I and C] technicians) are most often used to determine if an experienced employee is capable of performing maintenance tasks without further training. Such tests provide objective evidence for decisions to exempt an employee from what, for the employee, is unnecessary training. This leads to considerable savings in training costs and increased productivity because supervisors can assign personnel to tasks at which their competence is proven. The ultimate objective of proficiency evaluation is to ensure that qualified maintenance personnel are available to meet the maintenance requirements of the plant Numerous task-specific MPE tests (both written and performance) have been developed and validated using the EPRI MPE methodology by the utilities participating in the MPETB project A task-specific MPE consists of a multiple-choice written examination and a multi-step performance evaluation that can be used to assess an individual's present knowledge and skill level for a given maintenance task. The MPETB contains MPEs and test items for the mechanical, electrical, and I and C classifications that are readily available to participating utilities. Presently, utilities are placing emphasis on developing MPEs to evaluate outage-related maintenance tasks that demonstrate the competency and qualifications of plant and contractor personnel before the start of outage work. Utilities are also using the MPE methodology and process to

    To determine the relationships among traditional and laparoscopic surgical skills, spatial analysis skills, and video gaming proficiency of third-year veterinary students. Prospective, randomized, controlled study. A convenience sample of 29 third-year veterinary students. The students had completed basic surgical skills training with inanimate objects but had no experience with soft tissue, orthopedic, or laparoscopic surgery; the spatial analysis test; or the video games that were used in the study. Scores for traditional surgical, laparoscopic, spatial analysis, and video gaming skills were determined, and associations among these were analyzed by means of Spearman's rank order correlation coefficient (rs). A significant positive association (rs = 0.40) was detected between summary scores for video game performance and laparoscopic skills, but not between video game performance and traditional surgical skills scores. Spatial analysis scores were positively (rs = 0.30) associated with video game performance scores; however, that result was not significant. Spatial analysis scores were not significantly associated with laparoscopic surgical skills scores. Traditional surgical skills scores were not significantly associated with laparoscopic skills or spatial analysis scores. Results of this study indicated video game performance of third-year veterinary students was predictive of laparoscopic but not traditional surgical skills, suggesting that laparoscopic performance may be improved with video gaming experience. Additional studies would be required to identify methods for improvement of traditional surgical skills.

    Robinson-Cimpian, Joseph P; Lubienski, Sarah Theule; Ganley, Colleen M; Copur-Gencturk, Yasemin

    2014-04-01

    A recent wave of research suggests that teachers overrate the performance of girls relative to boys and hold more positive attitudes toward girls' mathematics abilities. However, these prior estimates of teachers' supposed female bias are potentially misleading because these estimates (and teachers themselves) confound achievement with teachers' perceptions of behavior and effort. Using data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K), Study 1 demonstrates that teachers actually rate boys' mathematics proficiency higher than that of girls when conditioning on both teachers' ratings of behavior and approaches to learning as well as past and current test scores. In other words, on average girls are only perceived to be as mathematically competent as similarly achieving boys when the girls are also seen as working harder, behaving better, and being more eager to learn. Study 2 uses mediation analysis with an instrumental-variables approach, as well as a matching strategy, to explore the extent to which this conditional underrating of girls may explain the widening gender gap in mathematics in early elementary school. We find robust evidence suggesting that underrating girls' mathematics proficiency accounts for a substantial portion of the development of the mathematics achievement gap between similarly performing and behaving boys and girls in the early grades.

    2013-07-01

    Full Text Available This paper looked at students’ perceived level of English proficiency among Dodoma secondary schools in Tanzania. Factors like attitude, anxiety, classroom activities, motivation, and learning resources were considered as influencing English learning. The study was guided by three theories: Input Hypothesis, Inter-language and Vygotsky’s theory of value. Correlation design was used to describe the association between the student and teacher-related factors and students’ perceived level of English proficiency. Purposive sampling was used to select 300 form three students. Questionnaires were used to collect data from the participants. Reliability of the research instrument was determined by conducting a pilot study. Pearson Descriptive statistics and Kendall’s Tau-b were used to analyze the data. The study revealed that the students’ perceived level of proficiency in spoken English was average. The findings indicated a significant positive correlation between perceived English proficiency and attitude toward the English language, classroom activities, teacher motivation, and classroom environment. It is suggested that further studies integrate qualitative research methods to the research design in order to get an in-depth understanding of students’ perception on English proficiency.

    Minimal access surgery for gastrointestinal cancer has short-term benefits but is associated with a proficiency-gain curve. The aim of this study was to define national proficiency-gain curves for minimal access colorectal and oesophagogastric surgery, and to determine the impact on clinical outcomes. All adult patients undergoing minimal access oesophageal, colonic and rectal surgery between 2002 and 2012 were identified from the Hospital Episode Statistics database. Proficiency-gain curves were created using risk-adjusted cumulative sum analysis. Change points were identified, and bootstrapping was performed with 1000 iterations to identify a confidence level. The primary outcome was 30-day mortality; secondary outcomes were 90-day mortality, reintervention, conversion and length of hospital stay. Some 1696, 15 008 and 16 701 minimal access oesophageal, rectal and colonic cancer resections were performed during the study period. The change point in the proficiency-gain curve for 30-day mortality for oesophageal, rectal and colonic surgery was 19 (confidence level 98·4 per cent), 20 (99·2 per cent) and three (99·5 per cent) procedures; the mortality rate fell from 4·0 to 2·0 per cent (relative risk reduction (RRR) 0·50, P = 0·033), from 2·1 to 1·2 per cent (RRR 0·43, P curve for reintervention in oesophageal, rectal and colonic resection was 19 (98·1 per cent), 32 (99·5 per cent) and 26 (99·2 per cent) procedures respectively. There were also significant proficiency-gain curves for 90-day mortality, conversion and length of stay. The introduction of minimal access gastrointestinal cancer surgery has been associated with a proficiency-gain curve for mortality and major morbidity at a national level. Unnecessary patient harm should be avoided by appropriate training and monitoring of new surgical techniques. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Full Text Available The aim of this investigation is to verify the difference between children with learning disabilities and children without learning disabilities through motor proficiency test of Bruininks and Ozeretsky (1978. The sample was constituted by 30 children, with 8-year average age, 15 males and 15 females, subdivided into two groups of 15 children from both sexes: children without learning disabilities attending 3rd grade and children with learning disabilities attending 2nd grade having failed a term once. All of them came from a middle class background, according to Grafar scale (adapted by Fonseca, 1991. All children presenting any other disabilities were excluded from the sample. Intelligence factor “G” was controlled by using a percentile, higher or equal to 50 (middle and high level, measured by Raven’s (1974 progressive combinations test. In motor proficiency, children with learning disabilities showed significant differences when compared with normal children of the same age, in all components of global, composed and fine motricity. The tests administered showed a strong correlation between the variables of the motor proficiency components. The results lead to the conclusion that there were significant differences in motor proficiency between normal children and children with learning disabilities, who showed specific motor difficulties evincing a more vulnerable motor profile and not the presence of neurological dysfunction signs.

    Full Text Available The effect of the patternmaker’s proficiency on the creation of clothing was investigated by the observation of the patternmaking process for clothing that satisfies the designer. We asked Japanese and French patternmakers to make a clothing pattern for the same design. The reasons for the differences in resultant clothing patterns and toiles made by the two patternmakers are discussed. Although the patternmaking processes used by the proficient patternmakers were similar, the resultant patterns were different owing to different recognition of the design. In particular, the shape and size of the collar that the designer emphasized in the illustration were different in the resultant patterns. Differences in patternmaking originated from differences in the patternmakers′ levels of expertise in terms of education, experience, and proficiency. However, the designer was satisfied with both patterns.

    2011-01-01

    The development of English language learners (ELLs) was explored from kindergarten through eighth grade within a nationally representative sample of first-time kindergartners (N = 19,890). Growth curve analyses indicated that, compared to native English speakers, ELLs were rated by teachers more favorably on approaches to learning, self control, and externalizing behaviors in kindergarten and generally continued to grow in a positive direction on these social/behavioral outcomes at a steeper rate compared to their native English-speaking peers, holding other factors constant. Differences in reading and math achievement between ELLs and native English speakers varied based on the grade at which English proficiency is attained. Specifically, ELLs who were proficient in English by kindergarten entry kept pace with native English speakers in both reading and math initially and over time; ELLs who were proficient by first grade had modest gaps in reading and math achievement compared to native English speakers that closed narrowly or persisted over time; and ELLs who were not proficient by first grade had the largest initial gaps in reading and math achievement compared to native speakers but the gap narrowed over time in reading and grew over time in math. Among those whose home language is not English, acquiring English proficiency by kindergarten entry was associated with better cognitive and behavioral outcomes through eighth grade compared to taking longer to achieve proficiency. Multinomial regression analyses indicated that child, family, and school characteristics predict achieving English proficiency by kindergarten entry compared to achieving proficiency later. Results are discussed in terms of policies and practices that can support ELL children’s growth and development. PMID:22389551

    1990-01-01

    This paper reports that the Environmental Protection Agency (EPA) has developed a voluntary program to evaluate radon reduction contractors and provide this information to the public, as part of activities mandated by the Indoor Radon Abatement Act (IRAA) of 1988. The Radon Contractor Proficiency Program consists of several elements that collectively help to ensure the proficiency of radon mitigators and give the public greater confidence in their capability. Contractors who participate in the program must pass a written examination, adhere to mitigation guidelines, keep records of work, meet continuing education requirements and pass a re-examination every two years. Upon meeting the program's requirements, mitigators are listed in EPA's National RCP Proficiency Report. The first Report released on May 15, 1990 listed 636 contractors. The second Report, to be release in August, will list 895 contractors, representing an increase of 40 per cent

    2008-01-01

    In the accreditation process of a radioactivity measurements laboratory, according to ISO standard 17025, proficiency tests play a fundamental role. These PTs constitute an irreplaceable tool for the validation of measuring methods. In the case of Spain, ENAC, which is the Spanish accreditation national body, requires that the laboratory has to take part in a PT for each one of the accredited measuring methods in the period of time between two reassessments of the accreditation, what happens every 4-5 years. In specific areas of determination procedures, among which radioactive measurements could be included, the number of methods which can be accredited is very large. The purpose of the present work is to establish a classification into families of the different radioactivity measurement procedures, as well as to establish complementary actions that guarantee that carrying out periodically proficiency-tests on any of the included procedures in each family, every measurement procedure include in that family is controlled, complying with the criteria established by ENAC

    2016-01-01

    The purpose of this study was to (1) examine differences in fundamental movement skills (FMS) proficiency, physical self-concept, and physical activity in children with and without developmental coordination disorder (DCD), and (2) determine the association of FMS proficiency with physical self-concept while considering key confounding factors. Participants included 43 children with DCD and 87 age-matched typically developing (TD) children. FMS proficiency was assessed using the Test of Gross Motor Development - second edition. Physical self-concept and physical activity were assessed using self-report questionnaires. A two-way (group by gender) ANCOVA was used to determine whether between-group differences existed in FMS proficiency, physical self-concept, and physical activity after controlling for age and BMI. Partial correlations and hierarchical multiple regression models were used to examine the relationship between FMS proficiency and physical self-concept. Compared with their TD peers, children with DCD displayed less proficiency in various components of FMS and viewed themselves as being less competent in physical coordination, sporting ability, and physical health. Physical coordination was a significant predictor of ability in object control skills. DCD status and gender were significant predictors of FMS proficiency. Future FMS interventions should target children with DCD and girls, and should emphasize improving object control skills proficiency and physical coordination. Children with DCD tend to have not only lower FMS proficiency than age-matched typically developing children but also lower physical self-concept. Self-perceptions of physical coordination by children with DCD are likely to be valuable contributors to development of object control skills. This may then help to develop their confidence in performing motor skills. Children with DCD need supportive programs that facilitate the development of object control skills. Efficacy of training

    This is a report of a study which evaluated simulation-based learning as a teaching strategy for improving participants' ENP reading proficiency in the senior college program of students whose first language is Chinese, not English. Simulation-based learning is known to be one of most effective teaching strategies in the healthcare professional curricula, which brings a clinical setting into the classroom. However, developing English reading skills for English written nursing journals through simulation-based learning in the nursing curricula, is largely unknown. We used a quasi-experimental approach with nonequivalent control group design to collect the causal connections between intervention and outcomes. 101 students were enrolled in this study (response rate 92.6%) of these 48 students volunteered for the intervention group, and 53 students for the control group. The findings indicated that the intervention group had significantly higher mean scores in ENP reading proficiency with unknown words in the article (p=.004), vocabulary (pdesigned research and a universal method of outcome measurement.

  13. Teaching and Learning the Language of Science: A Case Study of Academic Language Acquisition in a Dual Language Middle School

    Science.gov (United States)

    Gose, Robin Margaretha

    English language learners (EL) are the fastest growing sub-group of the student population in California, yet ELs also score the lowest on the science section of the California Standardized Tests. In the area of bilingual education, California has dramatically changed its approach to English learners since the passage of Proposition 227 in 1998, which called for most EL instruction to be conducted in English (Cummins, 2000; Echevarria, Vogt, & Short, 2008). In reality, this means that EL students are often placed in programs that focus on basic language skills rather than rigorous content, meaning that they are not getting access to grade level science content (Lee & Fradd, 1998). As a result, many EL students exit eighth grade without a strong foundation in science, and they continue to score below their English-speaking peers on standardized achievements. While the usefulness of the academic language construct remains controversial (Bailey, 2012), the language used in science instruction is nevertheless often unfamiliar to both EL and English proficient students. The discourse is frequently specialized for discipline-specific interactions and activities (Bailey, 2007; Lemke, 1990). This qualitative case study examined academic language instruction in three middle school science classrooms at a dual language charter school. The goal was to understand how teachers integrate academic language and content for linguistically diverse students. The findings fom this study indicate that targeting language instruction in isolation from science content instruction prohibits students from engaging in the "doing of science" and scientific discourse, or the ability to think, reason, and communicate about science. The recommendations of this study support authentically embedding language development into rigorous science instruction in order to maximize opportunities for learning in both domains.

    Full Text Available The study investigated the effect of problem-based learning through cognition-based tasks on speaking proficiency of Iranian intermediate EFL learners in comparison to the effect of objective-based tasks. To this end, a true experimental research design was employed. Ninety five (N=95 language learners studying at a language institute in the city of Esfahan, Iran were given an IELTS listening and speaking test as the proficiency test and 75 learners were selected. In the next phase of the study, a second IELTS speaking test was administered as the homogeneity test and the pre-test to seventy five (N=75 learners chosen from the population and forty-eight (N=48 homogeneous intermediate learners were selected for the study (i.e., 24 learners in control group and 24 in experimental one. The results of an independent-sample t-test gained from the study proved that not only does implementation of problem-based learning through cognition-based tasks significantly increased intermediate participants’ speaking proficiency, but also it had more positive effect in comparison to objective-based tasks on participants’ speaking proficiency. Therefore, it is suggested that problem-based learning ought to be taken into account by educational scholars, those in charge of syllabus, material producers, language teachers and language learners.

  15. Singing proficiency in the majority: normality and "phenotypes" of poor singing.

    Science.gov (United States)

    Dalla Bella, Simone; Berkowska, Magdalena

    2009-07-01

    Recent evidence indicates that the majority of occasional singers can carry a tune. For example, when asked to sing a well-known song (e.g., "Happy Birthday"), nonmusicians performing at a slow tempo are as proficient as professional singers. Yet, some occasional singers are poor singers, mostly in the pitch domain, and sometimes despite not having impoverished perception. Poor singing is not a monolithic deficit, but is likely to be characterized by a diversity of singing "phenotypes." Here we systematically examined singing proficiency in a group of occasional singers, with the goal of characterizing the different patterns of poor singing. Participants sang three well-known melodies (e.g., "Jingle Bells") at a natural tempo and at a slow tempo, as indicated by a metronome. For each rendition, we computed objective measures of pitch and time accuracy with an acoustical method. The results confirmed previous observations that the majority of occasional singers can sing in tune and in time. Moreover, singing at a slow tempo after the target melody to be imitated was presented with a metronome improved pitch and time accuracy. In general, poor singers were mostly impaired on the pitch dimension, although various patterns of impairment emerged. Pitch accuracy or time accuracy could be selectively impaired; moreover, absolute measures of singing proficiency (pitch or tempo transposition) dissociated from relative measures of proficiency (pitch intervals, relative duration). These patterns of dissociations point to a multicomponent system underlying proficient singing that fractionates as a result of a developmental anomaly.

    2014-08-01

    This paper present findings from a pre-service teacher development project that prepared novice teachers to promote English language and literacy development with inquiry-based science through a modified elementary science methods course and professional development for cooperating teachers. To study the project's impact on student learning, we administered a pre and post assessment to students (N = 191) of nine first year elementary teachers (grades 3 through 6) who experienced the intervention and who taught a common science unit. Preliminary results indicate that (1) student learning improved across all categories (science concepts, writing, and vocabulary)—although the effect varied by category, and (2) English Language Learner (ELL) learning gains were on par with non-ELLs, with differences across proficiency levels for vocabulary gain scores. These results warrant further analyses to understand the extent to which the intervention improved teacher practice and student learning. This study confirms the findings of previous research that the integration of science language and literacy practices can improve ELL achievement in science concepts, writing and vocabulary. In addition, the study indicates that it is possible to begin to link the practices taught in pre-service teacher preparation to novice teacher practice and student learning outcomes.

    The basic theory of the proficient machine system to be developed was studied. Important proficient techniques in manufacturing industries are becoming extinct because of insufficient succession to next generation. The proficient machine system was proposed to cope with such situation. This machine system includes the mechanism for progress and evolution of techniques and sensibilities to be adaptable to environmental changes by learning and recognizing various motions such as work and process. Consequently, the basic research fields are composed of thought, learning, perception and action. This machine requires not only deigned fixed functions but also introduction of the same proficient concept as human being to be adaptable to changes in situation, purpose, time and machine`s complexity. This report explains in detail the basic concept, system principle, approaching procedure and practical elemental technologies of the proficient machine system, and also describes the future prospect. 133 refs., 110 figs., 7 tabs.

    Recent reports indicate an increasing prevalence of overweight among Filipino children. Considering the known association of physical activity (PA) with obesity, this study reports the findings of an objective monitoring of PA in a sample of Filipino children. The study also explores the relationship of PA with fundamental movement skills (FMS) proficiency. Thirty-two children (6.54 ± 2.45 years old) wore an accelerometer for 7 days of PA monitoring and were assessed on five FMS (throw, catch, kick, run, jump). The children met the World Health Organization's recommendation of 60 min of PA per day, with more active time being accrued during weekdays than weekends. Children with greater FMS proficiency were found to spend more time in PA than those who were less skillful during weekends. Further research is recommended to examine PA and FMS proficiency associations, exploring the role of social interactions on weekends and weekdays. © 2014 Japan Pediatric Society.

A number of studies have reported positive impact of an inquiry-based instruction on student achievement, critical thinking skills, reasoning skills, attitude toward science, etc. So far, studies have focused on exploring how an intervention affects student achievement using teacher/researcher-generated measurement. Only a few studies have attempted to explore the long-term impacts of an intervention on student science achievement measured by standardized tests. The students' science and reading ITBS data was collected from 2000 to 2011 from a school district which had adopted the SWH approach as the main approach in science classrooms since 2002. The data consisted of 12,350 data points from 3,039 students. The multilevel model for change with discontinuity in elevation and slope technique was used to analyze changes in student science achievement growth trajectories prior and after adopting the SWH approach. The results showed that the SWH approach positively impacted students by initially raising science achievement scores. The initial impact was maintained and gradually increased when students were continuously exposed to the SWH approach. Disadvantaged students who were at risk of having low science achievement had bigger benefits from experience with the SWH approach. As a result, existing problematic achievement gaps were narrowed down. Moreover, students who started experience with the SWH approach as early as elementary school seemed to have better science achievement growth compared to students who started experiencing with the SWH approach only in high school. The results found in this study not only confirmed the positive impacts of the SWH approach on student achievement, but also demonstrated additive impacts found when students had longitudinal experiences

    Limited English proficiency can be a barrier to asthma care and is associated with poor outcomes. This study examines whether pediatric patients in Ohio with limited English proficiency experience lower asthma care quality or higher morbidity. We used electronic health records for asthma patients aged 2-17 years from a regional, urban, children's hospital in Ohio during 2011-2015. Community-level demographics were included from U.S. Census data. By using chi-square and t-tests, patients with limited English proficiency and bilingual English-speaking patients were compared with English-only patients. Five asthma outcomes-two quality and three morbidity measures-were modeled using generalized estimating equations. The study included 15 352 (84%) English-only patients, 1744 (10%) patients with limited English proficiency, and 1147 (6%) bilingual patients. Pulmonary function testing (quality measure) and multiple exacerbation visits (morbidity measure) did not differ by language group. Compared with English-only patients, bilingual patients had higher odds of ever having an exacerbation visit (morbidity measure) (adjusted odds ratio [aOR], 1.4; 95% confidence interval [CI], 1.2-1.6) but lower odds of admission to intensive care (morbidity measure) (aOR, 0.3; 95% CI, 0.2-0.7), while patients with limited English proficiency did not differ on either factor. Recommended follow-up after exacerbation (quality measure) was higher for limited English proficiency (aOR, 1.8; 95% CI, 1.4-2.3) and bilingual (aOR, 1.6; 95% CI, 1.3-2.1), compared with English-only patients. In this urban, pediatric population with reliable interpreter services, limited English proficiency was not associated with worse asthma care quality or morbidity.

    Full Text Available Many studies have confirmed the presence of a bilingual advantage which is manifested as enhanced cognitive and attention control. However, very few studies have investigated the role of second language proficiency on the modulation of conflict-monitoring in bilinguals. We investigated this by comparing high and low proficient Hindi-English bilinguals on a modified saccadic arrow Stroop task under different monitoring conditions, and tested the predictions of the bilingual executive control advantage proposal. The task of the participants was to make an eye movement towards the colour patch in the same colour as the central arrow, ignoring the patch to which the arrow was pointing. High-proficient bilinguals had overall faster saccade latency on all types of trials as compared to the low proficient bilinguals. The overall saccadic latency for high proficiency bilinguals was similarly affected by the different types of monitoring conditions, whereas conflict resolution advantage was found only for high monitoring demanding condition. The results support a conflict-monitoring account in a novel oculomotor task and also suggest that language proficiency could modulate executive control in bilinguals.

    This study examined the association between cell phone use, including minutes spent talking and number of text messages sent, and two measures of children’s reading proficiency — tests of word decoding and reading comprehension — in the United States. Data were drawn from the Child Development Supplement to the Panel Study of Income Dynamics, a nationally representative survey of 1,147 children 10–18 in 2009. Children whose parents were better educated, who had higher family incomes, who had fewer siblings, and who lived in urban areas were more likely to own or share a cell phone. Among those with access to a phone, children who spent more time talking on the phone were less proficient at word decoding, whereas children who spent more time sending text messages had greater reading comprehension. Although girls spent more time texting than did boys, there were no gender differences in the association between time spent talking or number of text messages sent with achievement. In spite of racial/ethnic differences in cell phone use levels, there were no racial/ethnic differences in the association between cell phone use and reading proficiency. PMID:27683624

  13. An exploration of elementary science teachers' expertise, creativity skills, and motivation in relation to the use of an innovation and the delivery of high-quality science instruction

    Science.gov (United States)

    Falkenberg, Karen L.

    This two-year study sought to uncover characteristic differences among a purposive sample of 23 elementary teachers who were using an elementary science innovation with various levels of proficiency. Two theoretical frameworks supported the development of the research, the Concerns Based Adoption Model Level of Use (LoU) (Hord, Rutherford, Huling-Austin & Hall, 1987) and Amabile's (1996) Componential Model of Creativity. Both qualitative and quantitative methodologies were employed to gather data on participants' science content knowledge, pedagogical skill, creativity relevant process skills, motivation orientation, self-efficacy, outcome expectancy and workplace environment. Results dispute the common conception among educators that "mechanical use" teachers do not provide high quality lessons. A new method for categorizing teachers' proficiency with an innovation is suggested by this study that incorporates both qualitative data from the LoU interview and classroom observation. Additionally, results show that the quality of the observed science lessons was associated with a teacher's creativity. The data suggest that a teacher's creativity relevant process skills and expertise are indicators of lesson quality. There were important differences among teachers' conceptions of creativity, how they involved students in the reported lessons and in the type of adaptations they made to the innovation. The more creative teachers tended to provide lessons that were more complex, of longer duration, had ties to student home life, and used multiple resources. Following an analysis of these results is a set of suggested professional development strategies and workplace changes to support less proficient teachers in their ability to provide higher quality elementary science lessons.

    Full Text Available This study examines the relationship between actual fundamental motor skill (FMS proficiency, perceived motor confidence and competence, and physical activity (PA among female children (n= 160; mean age = 10.69 ± 1.40 years. The Test of Gross Motor Development-2nd Edition (TGMD-2 was used to assess seven FMSs (locomotor, object-control, and stability. Motor confidence and competence were assessed using a valid skill-specific scale, and a modified version of the Self-Perception Profile for Children. PA levels were assessed using self-report (PA Questionnaire for Older Children (PAQ-C and classified as low, moderate, and high active. One-way and two-way ANOVAs (post-hoc honest significant difference (HSD and correlation coefficients were used to analyse the data. Findings indicate that the majority of youth (71.8% were not meeting the minimum 60 min of daily PA recommended for health, and that 98.1% did not achieve the FMS proficiency expected for their age. While there were high levels of perceived physical self-confidence (PSC reported within FMS skill-specific tasks, there was no significant correlation observed between actual FMS proficiency and perceived PSC among the cohort. Results show that low, moderately, and highly active female participants differ significantly in terms of their overall FMS (p = 0.03 and locomotor (LOC control scores (p = 0.03. Results from a two-way between-groups analysis of variance also revealed no statistically significant interaction effect between PA grouping and physical performance self-concept (PPSC on overall FMS proficiency levels. Results of a multiple linear regression indicate that perceived PSC is a significant predictor (beta = 0.183 of participants’ overall PA levels. Data show a need for targeting low levels of PA, and low FMS proficiency in female youth, and for developing interventions aiming to enhance perceived PSC levels.

    Waller, Samara Susan

    This study addressed a prevalence of low achievement in science courses in an urban school district in Georgia. National leaders and educators have identified the improvement of science proficiency as critical to the future of American industry. The purpose of this study was to examine parent involvement in this school district and its contribution to the academic achievement of successful science students. Social capital theory guided this study by suggesting that students achieve best when investments are made into their academic and social development. A collective case study qualitative research design was used to interview 9 parent participants at 2 elementary schools whose children scored in the exceeds category on the Science CRCT. The research questions focused on what these parents did at home to support their children's academic achievement. Data were collected using a semi-structured interview protocol and analyzed through the categorical aggregation of transcribed interviews. Key findings revealed that the parents invested time and resources in 3 practices: communicating high expectations, supporting and developing key skills, and communicating with teachers. These findings contribute to social change at both the local and community level by creating a starting point for teachers, principals, and district leaders to reexamine the value of parent input in the educational process, and by providing data to support the revision of current parent involvement policies. Possibilities for further study building upon the findings of this study may focus on student perceptions of their parents' parenting as it relates to their science achievement.

    Fundamental movement proficiency (FMS) is most successfully acquired during early school years. This cross-sectional study assessed FMS proficiency in Singaporean children at the start of and following 2.5 years of primary school physical education (PE). Participants were 244 children from Primary 1 and 3 levels. Fundamental movement skills (FMS) were assessed with the Test of Gross Motor Development-Second Edition (TGMD-2) that includes locomotor (LOCO) and object control (OC) subtests. Most children were rated "average" and "below average" for LOCO skills but "poor" and "below average" for OC skills without significant gender differences on either subtest or overall FMS proficiency and without FMS mastery. These young Singaporean children failed to exhibit age-appropriate FMS proficiency despite early PE exposure, and they demonstrated lags in FMS compared with the TGMD-2 U.S. normative sample. We discuss implications for sports competence perception, difficulty in coping with later movement learning expectations and reduced later motivation to participate in PE and play. We also discuss implications for preschool and lower primary school PE curricula with a particular focus on both OC skills and LOCO skills requiring muscular fitness like hopping and jumping.

  2. Training in summarizing notes: Effects of teaching students a self-regulation study strategy in science learning

    Science.gov (United States)

    Nebres, Michelle

    The last two decades of national data assessments reveal that there has been a sharp decline in nationwide standardized test scores. International assessment data show that in 2012 a very low amount of American students were performing at proficiency or above in science literacy. Research in science literacy education suggests that students benefit most when they are self-regulated (SR) learners. Unfortunately, SR poses a challenge for many students because students lack these skills. The effects of having learned few SR strategies at an early age may lead to long term learning difficulties--preventing students from achieving academic success in college and beyond. As a result, some researchers have begun to investigate how to best support students' SR skills. In order for studying to be successful, students need to know which SR study strategies to implement. This can be tricky for struggling students because they need study strategies that are well defined. This needs to be addressed through effective classroom instruction, and should be addressed prior to entering high school in order for students to be prepared for higher level learning. In this study, students underwent a treatment in which they were taught a SR study strategy called summarizing notes. A crossover repeated measures design was employed to understand the effectiveness of the treatment. Results indicated a weak, but positive correlation between how well students summarized notes and how well they performed on science tests. Self-regulation skills are needed because these are the types of skills young adults will use as they enter the workforce. As young adults began working in a professional setting, they will be expected to know how to observe and become proficient on their own. This study is pertinent to the educational field because it is an opportunity for students to increase SR, which affords students with the skills needed to be a lifelong learner.

Information literacy (IL skills were assessed using the Information Literacy Test (ILT developed and validated by researchers at James Madison University. During the spring and fall semesters of 2009 and 2011, the authors administered in a single session the ILT, pre-, and post-test survey instruments to 580 participants. Participants self-selected via sign-up sheet. The first hundred students to sign up per enrollment period were scheduled. Participants received incentives for participation, with an additional incentive offered for scoring in the top 15%. Main Results – The majority of students at both schools (95% at school 1, 80% at school 2 scored in the below-proficient range on the ILT, a few scored in the proficient range (5% at school 1, 20% at school 2, but no students scored in the advanced range. The mean of the few scores in the proficient range was closer to the below-proficient range (≤65% than the advanced range (≥90%. For students at both schools, significant differences were found between their self-estimated and actual test score. While students at both schools adjusted their self-estimated scores downward after completing the ILT, post-test self-estimates remained significantly inflated in relation to their test performance. In particular, students scoring in the below-proficient range demonstrated a large and significant gap. The difference

    Full Text Available Self-efficacy, which is the belief about one’s ability to perform a task successfully, has been widely acknowledged as important in learning. This affective factor, though not explicitly evident, has been said to play an important role in academic performance. However, its role in reading development has not been widely investigated. To determine the relationship between self-efficacy and reading proficiency, a study was conducted with first-year students in a South African tertiary institution. Students’ self-efficacy levels were elicited through a questionnaire and their reading proficiency was obtained through the Test of Academic Literacy levels (TALL, which essentially assesses reading proficiency. An analysis of variance showed a robust relationship between reading self-efficacy and reading proficiency for this cohort of students. Regression analysis conducted with other affective factors showed self-efficacy as the best predictor of students’ reading proficiency. Results are discussed as they relate to previous research and recommendations are made to include the development of self-efficacy in reading instruction.

    2009-03-01

    We analyze handwriting records from several school children with the aim of characterizing the fluctuating behavior of the writing speed. It will be concluded that remarkable differences exist between proficient and dysgraphic handwritings which were unknown so far. It is shown that in the case of proficient handwriting, the variations in handwriting speed are strongly autocorrelated within times corresponding to the completion of a single character or letter, while become uncorrelated at longer times. In the case of dysgraphia, such correlations persist on longer time scales and the autocorrelation function seems to display algebraic time decay, indicating the presence of strong anomalies in the handwriting process. Applications of the results in educational/clinical programs are envisaged.

    This study applies the Commission on Social Determinants of Health model to identify the effect of ethnicity/race and English proficiency on the health of older immigrants. California Health Interview Survey data of foreign-born respondents aged 65 and over were used to examine the four outcomes of health-related quality of life (HRQOL). The study included 1,196 immigrant Latinos, Asians, and non-Hispanic Whites. The results show that ethnicity/race-based differences in HRQOL exist. Furthermore, the results indicate that English proficiency has a significant moderating relationship on racial/ethnic background. The likelihood of reporting more Limited Combined Days increased with lower levels of English proficiency for both Latino and Asian-American old adults as compared to non-Hispanic Whites. In addition to focusing on racial disparities, health promotion efforts with older immigrants need to examine language-based stratification. Social work and gerontological advocates need to develop and employ evidence-based interventions that reach limited-English-proficient older immigrants to address the health, psychosocial, and access to health care challenges they face.

    2009-01-01

    Virtual reality (VR) simulators for laparoscopy and endoscopy may be valuable tools for resident education. However, the cost of such training in terms of trainee and instructor time may vary depending upon whether an independent or proctored approach is employed. We performed a randomized controlled trial to compare independent and proctored methods of proficiency-based VR simulator training. Medical students were randomized to independent or proctored training groups. Groups were compared with respect to the number of training hours and task repetitions required to achieve expert level proficiency on laparoscopic and endoscopic simulators. Cox regression modeling was used to compare time to proficiency between groups, with adjustment for appropriate covariates. Thirty-six medical students (18 independent, 18 proctored) were enrolled. Achievement of overall simulator proficiency required a median of 11 hours of training (range, 6-21 hours). Laparoscopic and endoscopic proficiency were achieved after a median of 11 (range, 6-32) and 10 (range, 5-27) task repetitions, respectively. The number of repetitions required to achieve proficiency was similar between groups. After adjustment for covariates, trainees in the independent group achieved simulator proficiency with significantly fewer hours of training (hazard ratio, 2.62; 95% confidence interval, 1.01-6.85; p = 0.048). Our study quantifies the cost, in instructor and trainee hours, of proficiency-based laparoscopic and endoscopic VR simulator training, and suggests that proctored instruction does not offer any advantages to trainees. The independent approach may be preferable for surgical residency programs desiring to implement VR simulator training.

  15. Choosing Science: A Mixed-Methods Study of Factors Predicting Latino and Latina High School Students' Decisions to Pursue Science Degrees

    Science.gov (United States)

    Stein, Rachel S.

    Latino/as are an increasingly large subset of the United States population; however, they continue to be underrepresented in science careers. Because of this increase, research regarding Latino/as has improved, but there are still many gaps in regards to gender-specific predictors to pursue science careers. To address this lack of literature, the purpose of this study is to extend previous research and to develop a model of variables that significantly contribute to science career choice among Latino and Latina students when they graduate from high school. In particular the study addressed the following research questions: (1) What are the differences in science outcomes for Latino and Latina students? (2) What are the differences in factors involved in science outcomes for Latino and Latina students? (3) For Latino and Latina students what are the differences in the factors that predict students' choice to pursue a science degree and/or high scores on the Future Plans in Science Scale? (4) What are the differences in how Latino and Latina students experience science, which account for high achieving students to choose to pursue a science major? This study utilized an explanatory mixed-method approach to examine how cognitive, institutional, and motivational factors may be interrelated and play a role in Latino/as choice to pursue science. The first phase of the study incorporated the collection of survey and database information from 12th grade students at two Southern California high schools. The second phase of the study utilized follow-up focus group interviews to explore the specific differential experiences and views of Latino and Latina students. The results of the study demonstrated multiple significant predictors. Science self-concept and views towards science outside of school were the most significant predictors of students' choice to pursue science. Male students also had major predictors of Spanish proficiency, teacher encouragement, religious views

  17. Immigration, language proficiency, and autobiographical memories: Lifespan distribution and second-language access.

    Science.gov (United States)

    Esposito, Alena G; Baker-Ward, Lynne

    2016-08-01

    This investigation examined two controversies in the autobiographical literature: how cross-language immigration affects the distribution of autobiographical memories across the lifespan and under what circumstances language-dependent recall is observed. Both Spanish/English bilingual immigrants and English monolingual non-immigrants participated in a cue word study, with the bilingual sample taking part in a within-subject language manipulation. The expected bump in the number of memories from early life was observed for non-immigrants but not immigrants, who reported more memories for events surrounding immigration. Aspects of the methodology addressed possible reasons for past discrepant findings. Language-dependent recall was influenced by second-language proficiency. Results were interpreted as evidence that bilinguals with high second-language proficiency, in contrast to those with lower second-language proficiency, access a single conceptual store through either language. The final multi-level model predicting language-dependent recall, including second-language proficiency, age of immigration, internal language, and cue word language, explained ¾ of the between-person variance and (1)/5 of the within-person variance. We arrive at two conclusions. First, major life transitions influence the distribution of memories. Second, concept representation across multiple languages follows a developmental model. In addition, the results underscore the importance of considering language experience in research involving memory reports.

    The Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) has been well validated as a training device for laparoscopic skills. It has been demonstrated that training to a level of proficiency on the simulator significantly improves operating room performance of laparoscopic cholecystectomy. The purpose of this project was to obtain a national standard of proficiency using the MIST-VR based on the performance of experienced laparoscopic surgeons. Surgeons attending the Society of American Gastrointestinal Endoscopic Surgeons (SAGES) 2004 Annual Scientific Meeting who had performed more than 100 laparoscopic procedures volunteered to participate. All the subjects completed a demographic questionnaire assessing laparoscopic and MIST-VR experience in the learning center of the SAGES 2004 meeting. Each subject performed two consecutive trials of the MIST-VR Core Skills 1 program at the medium setting. Each trial involved six basic tasks of increasing difficulty: acquire place (AP), transfer place (TP), traversal (TV), withdrawal insert (WI), diathermy task (DT), and manipulate diathermy (MD). Trial 1 was considered a "warm-up," and trial 2 functioned as the test trial proper. Subject performance was scored for time, errors, and economy of instrument movement for each task, and a cumulative total score was calculated. Trial 2 data are expressed as mean time in seconds in Table 2. Proficiency levels for laparoscopic skills have now been established on a national scale by experienced laparoscopic surgeons using the MIST-VR simulator. Residency programs, training centers, and practicing surgeons can now use these data as guidelines for performance criterion during MIST-VR skills training.

    Full Text Available ESL learners often experience anxiety and feel uncomfortable when speaking in the target language. This paper examines the anxiety level of polytechnic students when speaking English and the effects of board game on their speaking performance. The participants were selected from two intact classes which were randomly assigned into experimental and control groups comprising 30 students each. Data were obtained from pre- and post-treatment speaking tests and questionnaire. The questionnaire measuring anxiety factors was adapted from Yaikhong and Usaha (2012 and Woodrow (2006. The board game “What Say You” employed during the treatment was a speaking activity which required players to speak on a topic within a given time frame. The experimental group played the board games over six sessions. The results from the experimental and control groups showed significant difference in the pre- and post-treatment speaking test scores. However, the speaking performance of the experimental group revealed significantly higher scores. Students who were initially hesitant and passive were more willing to speak and were able to present and justify their ideas more confidently as compared to the control group after the treatment. The findings reveal that the board game is a useful tool to engage learners’ participation in class and to enhance the speaking ability of low-proficiency ESL learners.

    Minimally invasive surgery requires technical skills distinct from those used in conventional surgery. The aim of this prospective study was to identify personal characteristics that may predict the attainable proficiency level of first-time virtual reality laparoscopy (VRL) trainees. Two hundred and seventy-nine consecutive undergraduate medical students without experience attended a standardized VRL training. Performance data of an abstract and a procedural task were correlated with possible predictive factors providing potential competence in VRL. Median global score requirement status was 86.7% (interquartile range (IQR) 75-93) for the abstract task and 74.4% (IQR 67-88) for the procedural task. Unadjusted analysis showed significant increase in the global score in both tasks for trainees who had a gaming console at home and frequently used it as well as for trainees who felt self-confident to assist in a laparoscopic operation. Multiple logistic regression analysis identified frequency of video gaming (often/frequently vs. rarely/not at all, odds ratio: abstract model 2.1 (95% confidence interval 1.2; 3.6), P = 0.009; virtual reality operation procedure 2.4 (95% confidence interval 1.3; 4.2), P = 0.003) as a predictive factor for VRL performance. Frequency of video gaming is associated with quality of first-time VRL performance. Video game experience may be used as trainee selection criteria for tailored concepts of VRL training programs.

    The US EPA developed the voluntary Radon Measurement Proficiency Program in 1986 in response to a Federal and State need for measurement services firms to demonstrate their proficiency with radon measurement methods and devices. Since that time, the program has set basic standards for the radon measurement industry. The program has grown dramatically since its inception. In 1986, fewer than 50 companies participated in the program. By 1989, more than 5,000 companies were participating. Participants represent firms with an analytical capability as well as firms that rely upon another firm for analysis service. Since the beginning of the RMP Program, the Agency has learned a great deal about radon measurement methods and devices. This paper reviews the measurement devices used in the program and what the EPA has learned about them since the program's inception. Performance data from the RMP Program are used to highlight relevant findings

    Full Text Available Research on training in motivational interviewing (MI has shown eroding skills after workshops not followed by additional training input (supervision/coaching. There is a need for more research evaluating different types and lengths of post-workshop training with follow-up periods extending six months. This study is an extension of a previous evaluation of the level of proficiency in MI after workshop and four sessions of supervision among nurses in Swedish child health services.To explore the level of MI proficiency among nurses participating in an intervention to prevent childhood obesity (n = 33, after receiving five additional sessions of supervision including feedback on observed practice, as well as level of proficiency at follow-up.Level of proficiency was measured 4 and 12 months after completed supervision using recorded practice samples coded according to the Motivational Interviewing Treatment Integrity (MITI Code. Potential predictors of outcome were investigated.Proficiency remained on the same levels after nine sessions of supervision as after four sessions, and was generally low. The percentage of nurses reaching the proficiency level ranged from 18.2 to 54.5% across indicators. MI-spirit had increased significantly at follow-up, and the rest of the indicators remained on the same levels. No predictors of outcome were found.Comprehensive training programs with prolonged post-workshop supervision and feedback on observed practice may help to sustain but not improve participants' proficiency in MI. Potential explanations to the results and suggestions for future research are discussed.

    2013-07-01

    Full Text Available The New Malaysia Education Blueprint (2012 states that the private sector continues to have concerns for Malaysian graduates’ English proficiency. The present study investigates the views and expectations of science students taking English courses in a public university. The findings revealed that learners saw opportunities to communicate and job applications process as important soft skills. They preferred practical learning methods above traditional teaching methods. Learners considered group performance, personal attitudes and online activities as important learning opportunities, while factual knowledge, report writing were least supported despite the fact that the majority viewed both assessments and instructional process as relevant. The data revealed that though they were dissatisfied with their existing level of proficiency, many students continued to expect an A for their course. An assessment of the learner’s’ language ability revealed that language ability was less under the learner’s control and more dependent on learner proficiency level. Taken together, this study suggests that the curriculum for the Professional Writing course should be highly diversified and balanced, with some emphasis on getting less proficient learners to read and improve their grammar skills while better students should be given opportunities to develop creative talents and interpersonal skills.

  12. An exploratory study of proficient undergraduate Chemistry II students' application of Lewis's model

    Lewis, Sumudu R.

    This exploratory study was based on the assumption that proficiency in chemistry must not be determined exclusively on students' declarative and procedural knowledge, but it should be also described as the ability to use variety of reasoning strategies that enrich and diversify procedural methods. The study furthermore assumed that the ability to describe the structure of a molecule using Lewis's model and use it to predict its geometry as well as some of its properties is indicative of proficiency in the essential concepts of covalent bonding and molecule structure. The study therefore inquired into the reasoning methods and procedural techniques of proficient undergraduate Chemistry II students when solving problems, which require them to use Lewis's model. The research design included an original survey, designed by the researcher for this study, and two types of interviews, with students and course instructors. The purpose of the survey was two-fold. First and foremost, the survey provided a base for the student interview selection, and second it served as the foundation for the inquiry into the strategies the student use when solving survey problems. Twenty two students were interviewed over the course of the study. The interview with six instructors allowed to identify expected prior knowledge and skills, which the students should have acquired upon completion of the Chemistry I course. The data, including videos, audios, and photographs of the artifacts produced by students during the interviews, were organized and analyzed manually and using QSR NVivo 10. The research found and described the differences between proficient and non-proficient students' reasoning and procedural strategies when using Lewis's model to describe the structure of a molecule. One of the findings clearly showed that the proficient students used a variety of cues to reason, whereas other students used one memorized cue, or an algorithm, which often led to incorrect representations in

    The purpose of this study was to identify science teachers' perceptions concerning the use of technology in science laboratories and identify teachers' concerns and recommendations for improving students' learning. Survey methodology with electronic delivery was used to gather data from 164 science teachers representing Texas public schools. The data confirmed that weaknesses identified in the 1990s still exist. Lack of equipment, classroom space, and technology access, as well as large numbers of students, were reported as major barriers to the implementation of technology in science laboratories. Significant differences were found based on gender, grade level, certification type, years of experience, and technology proficiency. Females, elementary teachers, traditionally trained teachers, and less experienced teachers revealed a more positive attitude toward the use of technology in science laboratories. Participants in this study preferred using science software simulations to support rather than replace traditional science laboratories. Teachers in this study recommended professional development programs that focused on strategies for a technology integrated classroom.

    Bilingual immigrants appear to have a health advantage, and identifying the mechanisms responsible for this is of increasing interest to scholars and policy makers in the United States. Utilizing the National Latino and Asian American Study (NLAAS; n = 3,264), we investigate the associations between English and native-language proficiency and usage and self-rated health for Asian and Latino U.S. immigrants from China, the Philippines, Vietnam, Mexico, Cuba, and Puerto Rico. The findings demonstrate that across immigrant ethnic groups, being bilingual is associated with better self-rated physical and mental health relative to being proficient in only English or only a native language, and moreover, these associations are partially mediated by socioeconomic status and family support but not by acculturation, stress and discrimination, or health access and behaviors.

    The PIANOLIB activity aims to harmonize the calibrations of the measurement equipment in the region and to evaluate the quality of this kind of measurement by means of a proficiency test exercise. In this report the results of the proficiency test are presented. The exercise consisted in determining the activity of a phantom filled with two sets of certified radioactive materials, K-40 and Cs-137, in radioactive rods, uniformly spaced inside of the phantom. Most of the participants were able to quantify correctly the activities of K-40 and Cs-137 and by comparison with the results of a previous exercise of this kind, the overall performance is equally good. The problems experienced by laboratories which submitted non-acceptable results could generally be attributed to the calibration of their systems. It is important to keep the practice of intercomparison and NKS continues to be the best framework for supporting this kind of activity. (Author)

    Full Text Available Background: Limited tools exist to measure handwriting readiness skills of pre-kindergarten students. This study was a preliminary exploration of content validity of the Shore Handwriting Screening (SHS and the newly developed Score Sheet with the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2 in 4- and 5-year-old pre-kindergarten students. Because socioeconomic status (SES is known to impact handwriting skills, data from two different socioeconomic groups were collected. Method: Students from a Lower SES group (n = 36 and a Higher SES group (n = 14 completed the SHS and fine motor composite of the BOT-2. Pearson’s correlation was used to compare scores on the two assessments within the two groups. Results: SHS overall percentage scores were compared to standard scores and composite scores of the BOT-2. SHS scores displayed moderate to high correlation with fine manual control portions of the BOT-2 for the Lower SES group and low to moderate correlation for the same portion in the Higher SES group. Conclusion: SHS and the Score Sheet correlate to fine and visual-motor skill subtests on the fine manual control portions of the BOT-2, which supports the need for further research on the reliability and validity of the Score Sheet for use in practice.

  19. The Effectiveness of Traditional and 21st Century Teaching Tools on Students' Science Learning

    Science.gov (United States)

    Bellflower, Julie V.

    Any student seeking a high school diploma from the public school system in one U.S. state must pass the state's high school graduation test. In 2009, only 88% of students at one high school in the state met the basic proficiency requirements on the science portion of the test. Because improved science education has been identified as an explicit national goal, the purpose of this mixed methods study was to determine whether traditional teaching tools (notes, lecture, and textbook) or 21st century teaching tools (online tutorials, video games, YouTube, and virtual labs) lead to greater gains in students' science learning. Bruner's constructivist and Bandura's social cognitive theories served as the foundations for the study. Quantitative research questions were used to investigate the relationship between the type of teaching tools used and student learning gains. Quantitative data from students' pre and posttests were collected and analyzed using a dependent samples t-test. Qualitative data were collected through a focus group interview and participant journals. Analysis of the qualitative data included coding the data and writing a descriptive narrative to convey the findings. Results showed no statistically significant differences in students' science achievement: both types of teaching tools led to student learning gains. As a result, an action plan was developed to assist science educators in the implementation of traditional and 21st century teaching tools that can be used to improve students' science learning. Implications for positive social change included providing science educators with a specific plan of action that will enhance students' science learning, thereby increasing science scores on the state and other high stakes tests.

    Full Text Available This study sought to determine how the testing of skill proficiency is being conducted in physical education teacher education (PETE programs in the USA and how fitness or skill proficiencies, as attributes of a physical educator, are perceived. Participants were 312 college PETE program coordinators who completed an online survey about skill testing in their program. The eligible respondents yielded a 52.7% total response rate. Most participants believed that skill proficiency for PETE students was important, but only 46% of programs reported testing within their program. Many participants stated it was possible for their students to graduate without demonstrating proficiency in skill technique, yet were confident their students would pass an independent skill test. Only 46.2% of respondents indicated their students needed to demonstrate proper skill technique in order to graduate, and there was no consistent method of assessment. Responses were evenly split regarding the importance of a physical educator being able to demonstrate proper skill technique or be physically fit. The lack of skill testing in programs, combined with the variation in assessment, is concerning, and the development of a standardized skill-based test may provide more rigor to this important area of teacher credibility and effectiveness.

    1991-07-01

    The TOEFL is widely used by colleges and universities in the United States and Canada to measure the English language proficiency levels of hearing international applicants. At the National Technical Institute for the Deaf, a faculty committee recommended that this popular test instrument be used to measure the English reading skills of deaf international applicants to the National Technical Institute for the Deaf. This study examined the merits of using the TOEFL to measure the English reading ability of hearing post-secondary international students seeking admission to English-based colleges and universities. Forty-one hearing foreign students were tested in the fall of 1989 at the English Language Institute at SUNY Buffalo. The instruments chosen were both the TOEFL and the California Achievement Test of reading ability. The majority of the research subjects who scored between 400 and 500 on the TOEFL achieved a grade level of less than 8.0 on the California Achievement Test.

    Lopez-Ferrao, Julio E.

    The purpose of this study is to contribute to the understanding and explanation of the science achievement gap between Spanish-speaking English language learners (ELLs) and their mainstream peers. The sample of purposefully selected participants (N = 23) included students representing eight Spanish-speaking countries who attended three middle schools (grades 6th-8th), 11 boys and 12 girls, with different years of schooling in the United States, English proficiency levels, and science achievement levels. Data gathering strategies included individual interviews with participants, classroom observations, and analysis of secondary data sources on students' English language proficiency and science achievement. Data interpretation strategies using a critical-interpretive perspective consisted of coding and narrative analysis, including analyses of excerpts and case studies. Two major findings emerge from the study: (1) An inverse relation between participants' number of years of exposure to science learning in an English-only learning environment and their science achievement levels; and (2) specific participant-identified problems, such as learning the science vocabulary, writing in science, the use of mathematics in science, and the lack of sense making in the science classroom. Key recommendations comprise: (1) Acknowledging the value of dual language education; (2) supporting the science-literacy connection; (3) ensuring high-quality science through research-informed instructional strategies; and (4) assessing ELLs' science achievement.

    Paolucci, Judith Jean

    This study investigated adolescents' views about the nature of science (NOS) and conceptions of their gender identities, and revealed whether these conceptions and views are related to their science interest. Participants were 566 high school students enrolled in chemistry courses at three high schools in a New England state. A questionnaire was used to assess participants' science interest, gender role perceptions, and views about science, as well as to provide background and math and science achievement data. The study found that while student scores of NOS understanding did not differ by gender, some significant differences were noted on the student responses to statements about science. Students with higher-than-average science interest scores responded to these statements differently than students with lower science interest scores; their responses tended to more closely match statements about NOS taken from current reform documents. The study also found that math and science achievement, masculinity scores, and NOS scores accounted for a greater variance of science interest for girls than for boys, though all three also contributed significantly and positively to the regression equation for boys. These predictor variables predicted membership to the lower or higher science interest groups, but could not predict students' career aspiration groups. Thus, other mediating factors not considered in this study may translate high science interest to science career aspiration. The results of this study coed prior research, which found that science and math achievement and masculinity are positively and significantly related to science interest for boy boys and girls. Moreover, the study found that achievement in math and science courses is a greater predictor of science interest for girls than for boys. The results of this study provide a rationale for incorporating the nature of science into the science curriculum. Moreover, since the science interest of boys was

    This report summarises the results of the IAEA-CU-2006-11 proficiency test on the determination of gamma emitting radionuclides in air filters, organised within the frame of the IAEA Technical Cooperation project RER/8/009 ''Air Pollution Monitoring in the Mediterranean Region''. The proficiency test was conducted by the Reference Materials Group of the Chemistry Unit (Physics, Chemistry and Instrumentation Laboratory) of the IAEA's analytical laboratories located in Seibersdorf (Austria) in cooperation with the Radiological and Environmental Sciences Laboratory, Department of Energy in the United States of America. The objective of TC project RER/8/009 is to contribute to air quality improvement through the establishment of a network for air monitoring and the design of a remedial strategy where the monitoring shows poor air quality. A spiked air filter with known activities of gamma emitting radionuclides prepared by the Department of Energy of the United States of America was used in this proficiency test. 14 spiked filters were distributed to the participating laboratories in April 2006. The deadline for receiving the results from the participants was set at 31 July 2006. The participating laboratories were requested to analyse the samples employing the methods used in their routine work, so that their performance on the test samples could be directly related to the real performance of the laboratory. Each laboratory was given a confidential code to assure the anonymity of the evaluation results. From the 14 initially registered, 11 laboratories reported their results back to the IAEA. The analytical results of the participating laboratories were evaluated against the reference values assigned to the reference air filter, and a rating system was applied

    Setting standards and cutoff scores is essential to any measurement and evaluation practice. Two evaluation frameworks, norm-referenced (NR) and criterion-referenced (CR), have often been used for setting standards. Although setting fitness standards based on the NR evaluation is relatively easy as long as a nationally representative sample can be obtained and regularly updated, it has several limitations-namely, time dependency, population dependence, discouraging low-level performers, and favoring advantaged or punishing disadvantaged individuals. Fortunately, these limitations can be significantly eliminated by employing the CR evaluation, which was introduced to kinesiology by Safrit and colleagues in the 1980s and has been successfully applied to some practical problems (e.g., set health-related fitness standards for FITNESSGRAM). Yet, the CR evaluation has its own challenges, e.g., selecting an appropriate measure for a criterion behavior, when the expected relationship between the criterion behavior and a predictive measure is not clear, and when standards are not consistent among multiple field measures. Some of these challenges can be addressed by employing the latest statistical methods (e.g., test equating). This article provides a comprehensive review of the science and art of setting standards and cutoff scores in kinesiology. After a brief historical overview of the standard-setting practice in kinesiology is presented, a case analysis of a successful CR evaluation, along with related challenges, is described. Lessons learned from past and current practice as well as how to develop a defendable standard are described. Finally, future research needs and directions are outlined.

    One of the central challenges globalization and immigration present to education is how to construct school language policies, procedures, and curricula to support academic success of immigrant youth. This case-study compares and contrasts language experience narratives along Elena's developmental trajectory of becoming an urban science teacher. Elena reflects upon her early language experiences and her more recent experiences as a preservice science teacher in elementary dual language classrooms. The findings from Elena's early schooling experiences provide an analysis of the linkages between Elena's developing English proficiency, her Spanish proficiency, and her autobiographical reasoning. Elena's experiences as a preservice teacher in two elementary dual language classrooms indicates ways in which those experiences helped to reframe her views about the intersections between language learning and science learning. I propose the language experience narrative, as a subset of the life story, as a way to understand how preservice teachers reconstruct past language experiences, connect to the present, and anticipate future language practices.

    Accurate and internationally comparable human papillomavirus (HPV) DNA detection and typing services are essential for HPV vaccine research and surveillance. This study assessed the proficiency of different HPV typing services offered routinely in laboratories worldwide. The HPV Laboratory Network (LabNet) has designed international proficiency panels that can be regularly issued. The HPV genotyping proficiency panels of 2013 and 2014 contained 43 and 41 coded samples, respectively, composed of purified plasmids of sixteen HPV types (HPV 6, 11, 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68a and 68b) and 3 extraction controls. Proficient typing was defined as detection in both single and multiple infections of 50 International Units of HPV 16 and HPV 18 and 500 genome equivalents for the other 14 HPV types, with at least 97% specificity. Ninety-six laboratories submitted 136 datasets in 2013 and 121 laboratories submitted 148 datasets in 2014. Thirty-four different HPV genotyping assays were used, notably Linear Array, HPV Direct Flow-chip, GenoFlow HPV array, Anyplex HPV 28, Inno-LiPa, and PGMY-CHUV assays. A trend towards increased sensitivity and specificity was observed. In 2013, 59 data sets (44%) were 100% proficient compared to 86 data sets (59%) in 2014. This is a definite improvement compared to the first proficiency panel, issued in 2008, when only 19 data sets (26%) were fully proficient. The regularly issued global proficiency program has documented an ongoing worldwide improvement in comparability and reliability of HPV genotyping services. Copyright © 2018 Elsevier B.V.

    2015-03-01

    The course Scientific Inquiry at California State University was developed by faculty in biology, physics and English to meet ``writing proficiency'' requirements for non-science majors. Drawing from previous work in composition studies, the position that we take in this course is that we should be engaging students in writing that replicates the work that writing does in science, rather than replicating the particular structural conventions characteristic of scientific writing. That is, scientists use writing to have, remember, share, vet, challenge, and stabilize ideas, and our course requires students use writing to achieve those aims, rather than produce writing that obeys particular conventions of scientific writing. This talk will describe how we have integrated findings from composition studies with a course on scientific inquiry, and provide examples of how scientific communication has resulted from this dialogue.

    Full Text Available Although the foreign-language profession routinely stresses the importance of technology for the curriculum, many teachers still harbor deep-seated doubts as to whether or not a hybrid course, much less a completely distance-learning class, could provide L2 learners with a way to reach linguistic proficiency, especially with respect to oral language skills. In this study, we examine the case of Spanish Without Walls (SWW, a first-year language course offered at the University of California - Davis in both hybrid and distance-learning formats. The SWW curriculum includes materials delivered via CD-ROM/DVD programs, online content-based web pages, and synchronous bimodal chat that includes sound and text. The contribution of each of these components is evaluated in the context of a successful technologically assisted course. To address the issue of oral proficiency, we compare the results from both classroom and distance-learning students who took the 20-minute Versant for Spanish test, delivered by phone and automatically graded. The data generated by this instrument shows that classroom, hybrid, and distance L2 learners reach comparable levels of oral proficiency during their first year of study. Reference is also made to two other ongoing efforts to provide distance-learning courses in Arabic and Punjabi, two languages where special difficulties in their writing systems have an impact on the design of the distant-learning format. The rationale for offering language courses in either a hybrid or distance-learning format is examined in light of increasing societal pressures to help L2 learners reach advanced proficiency, especially in less commonly taught languages (LCTLs.

    Paul Leslie Gardner pioneered the study of student difficulties with everyday words presented in the science context (Gardner 1971); several similarly designed studies (e.g. Cassels and Johnstone 1985; Tao in Research in Science Education, 24, 322-330, 1994; Farell and Ventura in Language and Education, 12(4), 243-254, 1998; Childs and O'Farell in Chemistry Education: Research and Practice, 4(3), 233-247, 2003) have since been reported in literature. This article draws from an exploratory study of the difficulties South African High School physical science learners encounter with everyday English words when presented in the science context. The participants (1107 learners and 35 respective physical science teachers) were drawn from 35 public secondary schools in Johannesburg area of South Africa. Data were obtained through a word test to participant learners followed by group interviews but face-to-face interviews with each physical science teacher. This study has revealed that in similar ways as have been reported in each of the studies so far, South African learners also face difficulties with meanings of everyday words presented in a science context. The main source of difficulties encountered was learner inability to distinguish between the meanings of familiar everyday words as used in everyday parlance from the `new' meanings of the same everyday words when used in the science context. Interpretations of learner interview responses revealed that fewer difficulties would have been experienced by learners if science teachers generally explained the context meanings of the words as used during science teaching. The findings suggest that focusing on contextual proficiency more than on general proficiency in the language of learning and teaching (LOLT) during teaching perhaps holds more promise for enhanced learning and achievement in science. Steps necessary to raise teacher awareness of the potential impact of context on meanings of everyday words of the LOLT

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

    2014-06-01

    Full Text Available Language clubs have been reported to be effective in learning languages, increasing motivation and independence (Gao, 2009. The present study was an attempt to investigate the effect of a web-based language club on the language proficiency of Iranian EFL learners. A number of pre-intermediate learners form two universities (118 were selected among 154 through a test of proficiency (TOEFL PBL, then they were put into experimental and control groups. The participants in experimental group got on line and acted as a member of a virtual language club for a period of 6 months. They got involved with activities like emailing, chatting, and weblogging. Data were collected through TOEFL PBL. The analyzed data from the test of proficiency indicated the outperformance of those in experimental group. Consequently, it might be proposed that web-based language clubs can make language learning easier and more efficient.

    The purpose of this experiment was to investigate whether classroom reverberation influences second-language (L2) listening comprehension. Moreover, we investigated whether individual differences in baseline L2 proficiency and in working memory capacity (WMC) modulate the effect of reverberation time on L2 listening comprehension. The results showed that L2 listening comprehension decreased as reverberation time increased. Participants with higher baseline L2 proficiency were less susceptible to this effect. WMC was also related to the effect of reverberation (although just barely significant), but the effect of WMC was eliminated when baseline L2 proficiency was statistically controlled. Taken together, the results suggest that top-down cognitive capabilities support listening in adverse conditions. Potential implications for the Swedish national tests in English are discussed. © 2014 The Authors.

    2015-02-01

    The ability to quantify differences in walking balance proficiency is critical to curbing the rising health and financial costs of falls. Current laboratory-based approaches typically focus on successful recovery of balance while clinical instruments often pose little difficulty for all but the most impaired patients. Rarely do they test motor behaviors of sufficient difficulty to evoke failures in balance control limiting their ability to quantify balance proficiency. Our objective was to test whether a simple beam-walking task could quantify differences in walking balance proficiency across a range of sensorimotor abilities. Ten experts, ten novices, and five individuals with transtibial limb loss performed six walking trials across three different width beams. Walking balance proficiency was quantified as the ratio of distance walked to total possible distance. Balance proficiency was not significantly different between cohorts on the wide-beam, but clear differences between cohorts on the mid and narrow-beams were identified. Experts walked a greater distance than novices on the mid-beam (average of 3.63±0.04m verus 2.70±0.21m out of 3.66m; p=0.009), and novices walked further than amputees (1.52±0.20m; p=0.03). Amputees were unable to walk on the narrow-beam, while experts walked further (3.07±0.14m) than novices (1.55±0.26m; p=0.0005). A simple beam-walking task and an easily collected measure of distance traveled detected differences in walking balance proficiency across sensorimotor abilities. This approach provides a means to safely study and evaluate successes and failures in walking balance in the clinic or lab. It may prove useful in identifying mechanisms underlying falls versus fall recoveries. Copyright © 2015 Elsevier B.V. All rights reserved.

    This systematic review examines the proficiency and visual search strategies of individuals with autism spectrum disorders (ASD) while disembedding figures and whether they differ from typical controls and other comparative samples. Five databases, including Proquest, Psychinfo, Medline, CINAHL and Science Direct were used to identify published studies meeting the inclusion and exclusion criteria. Twenty articles were included in the review, the majority of which matched participants by mental age. Outcomes discussed were time taken to identify targets, the number correctly identified, and fixation frequency and duration. Individuals with ASD perform at the same speed or faster than controls and other clinical samples. However, there appear to be no differences between individuals with ASD and controls for number of correctly identified targets. Only one study examined visual search strategies and suggests that individuals with ASD exhibit shorter first and final fixations to targets compared with controls.

  4. Defining English Language Proficiency for Malaysian Tertiary Education: Past, Present and Future Efforts

    Directory of Open Access Journals (Sweden)

    Chan Swee Heng

    2012-07-01

    Full Text Available Any attempt to define English language proficiency can never be divorced from the theories that describe the nature of language, language acquisition and human cognition. By virtue of such theories being socially constructed, the descriptions are necessarily value-laden. Thus, a definition of language proficiency can only, at best, be described as developmental, following changes that are linguistic, pragmatic, cultural and political. In defining English proficiency for tertiary education, the context is naturally also linked to the focus on university education. The argument has been that an ‘acceptable’ level of language competence of a university applicant is anything but constant. Tremendous social changes have seen traditional values of elitism in university education giving way to the ‘massification’ of education. As Kaplan and Baldauf (1997:257 affirms, “The principal problem in tertiary education is not declining literacy standards but rather it is about meeting changed societal, cultural and informational requirements and circumstances”. In the light of these changes, this paper attempts to trace influencing factors that help define an ‘acceptable’ level of English proficiency for Malaysian tertiary education. The paper examines past and present efforts of establishing an English language policy and assessment practice for tertiary education, and concludes with some views on future development that could evolve from the current indicative pursuits of establishing language learning and ability.

    Clarke, William Gordon

    English language learners (ELLs) demonstrate lower academic performance and have lower graduation and higher dropout rates than their non-ELL peers. The primary purpose of this correlational quantitative study was to investigate the relationship between the use of graphic organizer-infused science instruction and science learning of high school ELLs. Another objective was to determine if the method of instruction, socioeconomic status (SES), gender, and English language proficiency (ELP) were predictors of academic achievement of high school ELLs. Data were gathered from a New York City (NYC) high school fall 2012-2013 archival records of 145 ninth-grade ELLs who had received biology instruction in freestanding English as a second language (ESL) classes, followed by a test of their learning of the material. Fifty-four (37.2%) of these records were of students who had learned science by the conventional textbook method, and 91 (62.8%) by using graphic organizers. Data analysis employed the Statistical Package for the Social Sciences (SPSS) software for multiple regression analysis, which found graphic organizer use to be a significant predictor of New York State Regents Living Environment (NYSRLE) test scores (p < .01). One significant regression model was returned whereby, when combined, the four predictor variables (method of instruction, SES, gender, and ELP) explained 36% of the variance of the NYSRLE score. Implications of the study findings noted graphic organizer use as advantageous for ELL science achievement. Recommendations made for practice were for (a) the adoption of graphic organizer infused-instruction, (b) establishment of a protocol for the implementation of graphic organizer-infused instruction, and (c) increased length of graphic organizer instructional time. Recommendations made for future research were (a) a replication quantitative correlational study in two or more high schools, (b) a quantitative quasi-experimental quantitative study to

  10. A National Study of the Relationship between Home Access to a Computer and Academic Performance Scores of Grade 12 U.S. Science Students: An Analysis of the 2009 NAEP Data

    Science.gov (United States)

    Coffman, Mitchell Ward

    The purpose of this dissertation was to examine the relationship between student access to a computer at home and academic achievement. The 2009 National Assessment of Educational Progress (NAEP) dataset was probed using the National Data Explorer (NDE) to investigate correlations in the subsets of SES, Parental Education, Race, and Gender as it relates to access of a home computer and improved performance scores for U.S. public school grade 12 science students. A causal-comparative approach was employed seeking clarity on the relationship between home access and performance scores. The influence of home access cannot overcome the challenges students of lower SES face. The achievement gap, or a second digital divide, for underprivileged classes of students, including minorities does not appear to contract via student access to a home computer. Nonetheless, in tests for significance, statistically significant improvement in science performance scores was reported for those having access to a computer at home compared to those not having access. Additionally, regression models reported evidence of correlations between and among subsets of controls for the demographic factors gender, race, and socioeconomic status. Variability in these correlations was high; suggesting influence from unobserved factors may have more impact upon the dependent variable. Having access to a computer at home increases performance scores for grade 12 general science students of all races, genders and socioeconomic levels. However, the performance gap is roughly equivalent to the existing performance gap of the national average for science scores, suggesting little influence from access to a computer on academic achievement. The variability of scores reported in the regression analysis models reflects a moderate to low effect, suggesting an absence of causation. These statistical results are accurate and confirm the literature review, whereby having access to a computer at home and the

    2015-01-01

    Full Text Available General English (L2 proficiency and reading strategies are believed to be highly effective in successful reading performance. However, available studies rarely investigated the combined effects of these two variables on successful reading. To fill this gap, 78 university students were divided into four groups of different degrees of these two variables in L2 and given a reading test in English and an interview for assessing how much of the problems in L2 reading among the four groups were rooted in linguistic competence and/or strategic competence. Findings evinced that the high general proficiency level coupled with high awareness and use of reading strategies would result in best performance and that the pattern of answers to different components of reading question is different in different groups. It is concluded that both of the variables should be emphasized simultaneously for the best performance in reading comprehension.

    2008-08-08

    The purpose of this paper was to investigate whether perceived sports competence mediates the relationship between childhood motor skill proficiency and subsequent adolescent physical activity and fitness. In 2000, children's motor skill proficiency was assessed as part of a school-based physical activity intervention. In 2006/07, participants were followed up as part of the Physical Activity and Skills Study and completed assessments for perceived sports competence (Physical Self-Perception Profile), physical activity (Adolescent Physical Activity Recall Questionnaire) and cardiorespiratory fitness (Multistage Fitness Test). Structural equation modelling techniques were used to determine whether perceived sports competence mediated between childhood object control skill proficiency (composite score of kick, catch and overhand throw), and subsequent adolescent self-reported time in moderate-to-vigorous physical activity and cardiorespiratory fitness. Of 928 original intervention participants, 481 were located in 28 schools and 276 (57%) were assessed with at least one follow-up measure. Slightly more than half were female (52.4%) with a mean age of 16.4 years (range 14.2 to 18.3 yrs). Relevant assessments were completed by 250 (90.6%) students for the Physical Activity Model and 227 (82.3%) for the Fitness Model. Both hypothesised mediation models had a good fit to the observed data, with the Physical Activity Model accounting for 18% (R2 = 0.18) of physical activity variance and the Fitness Model accounting for 30% (R2 = 0.30) of fitness variance. Sex did not act as a moderator in either model. Developing a high perceived sports competence through object control skill development in childhood is important for both boys and girls in determining adolescent physical activity participation and fitness. Our findings highlight the need for interventions to target and improve the perceived sports competence of youth.

Methods In 2000, children's motor skill proficiency was assessed as part of a school-based physical activity intervention. In 2006/07, participants were followed up as part of the Physical Activity and Skills Study and completed assessments for perceived sports competence (Physical Self-Perception Profile, physical activity (Adolescent Physical Activity Recall Questionnaire and cardiorespiratory fitness (Multistage Fitness Test. Structural equation modelling techniques were used to determine whether perceived sports competence mediated between childhood object control skill proficiency (composite score of kick, catch and overhand throw, and subsequent adolescent self-reported time in moderate-to-vigorous physical activity and cardiorespiratory fitness. Results Of 928 original intervention participants, 481 were located in 28 schools and 276 (57% were assessed with at least one follow-up measure. Slightly more than half were female (52.4% with a mean age of 16.4 years (range 14.2 to 18.3 yrs. Relevant assessments were completed by 250 (90.6% students for the Physical Activity Model and 227 (82.3% for the Fitness Model. Both hypothesised mediation models had a good fit to the observed data, with the Physical Activity Model accounting for 18% (R2 = 0.18 of physical activity variance and the Fitness Model accounting for 30% (R2 = 0.30 of fitness variance. Sex did not act as a moderator in either model. Conclusion Developing a high perceived sports competence through object control skill development in childhood is important for both boys and girls in determining adolescent physical activity participation and fitness. Our findings highlight the need for interventions to target and improve the perceived sports competence of youth.

    Full Text Available Learning second language considers a number of factors that influence the manner in which the language is taught. Understanding of the learners’ goals and motivation for learning is one. Using descriptive-correlational research design, this study determined the influence of student English utility and teacher efficacy on the students’ English proficiency. A total of 101 students from first year to fourth year level served as the respondents of the study. The study quantified the students’ perception towards English utility and their evaluation of English teacher efficacy which employed a researcher-made survey questionnaire. Results revealed high positive perceptions of students towards English utility. Analysis of variance revealed significant differences in the perceptions of high school students on the efficacy of their English teachers. Correlation coefficients indicated a positive linear relationship among the given variables. The p-value revealed significant relationship of teacher efficacy (r = .691, p-value = .000 and English utility (r = .467, p-value = .000 to students’ English proficiency. Results of regression statistics revealed that English utility has no significant influence on the student English proficiency. Therefore, the main factor that must still be considered then should be the teacher. Finally, there is an explicit indication that high level of teachers’ efficacy performing in teaching has much powerful influence on the English proficiency of high school students. Thus improving the methods of teaching English provides a better way of motivating students to achieve higher levels of proficiency in the future.

  20. Proficiency evaluation of maintenance personnel: Training equivalency determination

    Price, W.J.

    1991-01-01

    The nuclear industry has recognized the importance of safe, quality, productive maintenance practices and has taken a number of initiatives that have generally improved maintenance programs. Because proficient maintenance practices are critical to plant safety and reliability, most plants have also recognized the need for reliable, valid testing techniques that demonstrate and assure the competence of their maintenance personnel. Until now, resource demands were too great to develop in-plant testing programs. In the past, maintenance supervisors have exempted personnel from training, using informal judgment of the employees' previous training and experience and informal observation of the employee on the job. While this procedure may have some degree of validity, it fails to provide the documentation for training equivalency that is required to satisfy the US Nuclear Regulatory Commission (NRC) regulations and Institute of Nuclear Power Operations (INPO) guidelines. To assess and demonstrate the proficiency levels of personnel, Calvert Cliffs needed to establish an objective, reliable, time-saving, and valid system to evaluate the competency levels of personnel. This was done in a joint effort with the Electric Power Research Institute

    Childbirth is the most common reason women are hospitalized in the United States. Understanding (1) how expectant mothers gather information to decide where to give birth, and (2) who helps make that decision, provides critical health communication and decision-making insights. Diverse Asian American and Pacific Islander (AA/PI) perspectives on such topics are understudied, particularly among those with limited English proficiency (LEP). LEP is defined as having a limited ability to read, write, speak, or understand English. To address this research gap, we interviewed 400 women (18+ years) with a recent live birth on O'ahu, Hawai'i. Participants completed a 1-hour, in-person interview in English (n=291), Tagalog (n=42), Chinese (n=36), or Marshallese (n=31). Women were asked (1) what information was most important in deciding where to deliver and why; and (2) who participated in the decision-making and why. Responses were compared by LEP (n=71; 18%) vs English-proficient (n=329; 82%) in qualitative and quantitative analyses. Both LEP and English-proficient participants reported their obstetrician as the most important source of health information. Significantly more LEP participants valued advice from family or acquaintances as important sources of information compared to English-proficient participants. The top three health decision-makers for both those with LEP and English-proficient participants were themselves, their obstetrician, and their spouse, which did not differ significantly by language proficiency. These findings provide insights into health information sources and decision-making across diverse AA/PI populations, including those with LEP, and can help direct health interventions such as disseminating patient education and healthcare quality information.

    According to the ionizing radiation safety regulation approved by the ROC Atomic Energy Council (AEC), personnel dosimeter processors shall be accredited by the Chinese National Laboratory Accreditation (CNLA) program before offering dosimeter services and shall be accredited every two years (now has been rescheduled to be every three years since 1996). The aim of this program is to secure quality and technical capability of personnel dosimeters, and to provide systematic improvement for the internal calibration and testing laboratory applying for accreditation by means of assessment procedures. The criteria used to evaluate the capability at laboratories are ISO/IEC 25 (1990) and technical guide in different accreditation fields. The Institute of Nuclear Energy Research (INER) was entrusted by CNLA as the central laboratory to perform the proficiency test of personnel dosimeters for laboratory accreditation in December 1990. Such proficiency tests, based on ANSI N13.11 (1983), which is mainly separated to accident categories and protection categories which consists of eight parts of tests including single and mixture radiation of x-ray, gamma, beta and neutron, have been conducted four times, in 1991, 1993, 1995 and 1998. This paper deals with the test procedures and results of proficiency tests of personnel dosimeters from 1991 until 1998. The results of the four proficiency tests showed that, for accident categories, the pass rate is about 91%; for protection categories, the pass rate is about 98%. Meanwhile, the central laboratory will adopt a new version of HPS N13.11 (1993) to replace ANSI N13.11 (1983) as new criteria for the next proficiency test to be conducted in 2001. (author)

    Full Text Available Employability of graduates is a concern in many countries, including Malaysia, and the high unemployment rate among graduates is often attributed to their lack of English proficiency and communication skills. These two distinctive elements are often collated, and it is important to find out which is more important to employers. The study examined the employers’ views on the importance of English proficiency and communication skill for graduates to be employed in the Malaysian private sector. The data were from semi-structured interviews conducted with 10 employers in the private sector who were in the position to recruit staff. The 21,433-word interview transcripts were analyzed. The results revealed that employers in the Malaysian private sector view language proficiency and communication skills as separate qualities. The employers are willing to consider employing candidates with average English proficiency if they have good communication skills, except for jobs which require more communication in English such as customer service and marketing. The results also revealed that good communication skills can increase employability and opportunities for career advancement. The findings highlight the communication skills that universities need to emphasize so that their graduates have the necessary skills to perform well in employment interviews and in their work.

    The proficiency tests are widely used to evaluate the analytical capacity of laboratories and also as part of the accreditation process. For this reason, are important tools for the control of the quality of the analytical results obtained in the laboratories that work directly with seafood companies. In Brazil there are no providers of proficiency testing for metals potentially toxic in fish tissues. In this work will be described all steps used for the production of reference materials to be used in a proficiency testing pilot study for As, Cd, Pb and Hg in fish tissue following the recommendations of the ISO Guide 35. He preparation scheme consisted in selecting the individuals, cleaning, grinding, homogenization and fortification with As, Cd and Pb in two concentration levels. The preparation resulted in 164 sachets of 10 g each. In order to evaluate the effect of gamma irradiation in the samples conservation 52 sachets were irradiated with {sup 60}Co (10.00 {+-} 1.05 kGy) in a gamma cell. This material with others non irradiated 52 sachets were used for the homogeneity and stability studies. The remaining 60 were used for the proficiency testing. The results demonstrated that both materials were homogeneous and presented good stability (during a period of 45 days). However, the irradiated material present better integrity, concerning biological degradation, when stored in ambient temperature. For this reason they were used to the proficiency testing pilot program. Ten laboratories participated in the proficiency testing pilot study and the results were evaluated using the following tests: z-score, confidence ellipse and En numbers. This work demonstrates the capability of the laboratory to produce reference materials as well as to organize and conduct proficiency testing. (author)

    Full Text Available Motor development is influenced by many factors such as practice and appropriate instruction, provided by teachers, even in preschool and elementary school. The goal of this paper was to discuss the misconception that maturation underlies children's motor skill development and to show that physical education, even in early years of our school system, is critical to promote proficiency and enrolment of children's in later motor activities. Motor skill development, as a curricular focus, has been marginalized in many of our physical education proposal and in doing so, we have not promote motor competence in our children who lack proficiency to engage and to participate in later motor activities such as sport-related or recreational.

    To examine the influence of quarter outcome and the margin of the score differential on both the physical activity profile and skill performance of players during professional Australian Football matches. Prospective, longitudinal. Physical activity profiles were assessed via microtechnology (Global Positioning System and accelerometer) from 40 professional AF players from the same team during 15 Australian Football League games. Skill performance measures (involvement and effectiveness) and player rank scores (Champion Data(©) Rank) were provided by a commercial statistical provider. The physical performance variables, skill involvements and individual player performance scores were expressed relative to playing time for each quarter. The influence of the quarter result (i.e. win vs. loss) and score margin (i.e. small: 19 points) on activity profile and skill involvements and skill efficiency performance of players were examined. Skill involvements (total disposals/min, long kicks/min, marks/min, running bounces/min and player rank/min) were greater in quarters won (all p14.5 km h(-1), HSR/min), sprints/min and peak speed were higher in losing quarters (all pProfessional AF players are likely to have an increased physical activity profile and decreased skill involvement and proficiency when their team is less successful.

    Now in its fourth year, "In the Footsteps of Roger Revelle" (IFRR) is a middle school science education program that draws student interest, scientific content and coherence with National Science Standards from real-time research at sea in fields of physical science. As a successful collaboration involving Scripps Institution of Oceanography (SIO), Woods Hole Oceanographic Institution (WHOI), National Oceanic and Atmospheric Administration (NOAA), Office of Naval Research (ONR), National Science Foundation (NSF), San Diego County Office of Education (SDCOE), and San Marcos Middle School (SMMS), IFRR brings physical oceanography and related sciences to students at the San Marcos Middle School in real-time from research vessels at sea using SIO's HiSeasNet satellite communication system. With their science teacher on the ship as an education outreach specialist or ashore guiding students in their interactions with selected scientists at sea, students observe shipboard research being carried out live via videoconference, daily e-mails, interviews, digital whiteboard sessions, and web interaction. Students then research, design, develop, deploy, and field-test their own data-collecting physical oceanography instruments in their classroom. The online interactive curriculum encourages active inquiry with intellectually stimulating problem-solving, enabling students to gain critical insight and skill while investigating some of the most provocative questions of our time, and seeing scientists as role- models. Recent science test scores with IFRR students have shown significant increases in classes where this curriculum has been implemented as compared to other classes where the traditional curriculum has been used. IFRR has provided students in the San Diego area with a unique opportunity for learning about oceanographic research, which could inspire students to become oceanographers or at least scientifically literate citizens - a benefit for a country that depends

    Proficiency tests (PT) are extensively used to evaluate the analytical competence of laboratories, and are also used as a part of accreditation processes. For this reason are important tool for quality control of laboratories including laboratories that act directly with food exporting companies. In Brazil there are no providers of proficiency testing for toxic metals, such as arsenic in fish tissue. This study presents a protocol to produce reference material to be used in proficiency test for arsenic in fish tissue following the recommendations of the ISO Guide 35. The preparation scheme consisted of: selecting of individuals, cleaning of scale and skin, trituration, homogenization, and spiking with arsenic at two levels of concentration. The mixture was then irradiated in a cyclotron Cyclone 30 Applications ion beam with cobalt 60 at 10.00 ± 1.05 KGy, before being packed into sachets. To verify the efficacy of the irradiation procedure, 26 (randomly selected) irradiated sachets and 26 non-irradiated sachets were assessed for homogeneity and stability. The results indicate that irradiation with cobalt 60 is crucial for ensuring the preservation of the integrity of the material, providing stable material at room temperature for 2 months. The samples can therefore be transported at room temperature. (author)

    Full Text Available This paper describes an ongoing project to create an online version of a reading programme, a custom-designed English language proficiency course at a university in Japan. Following an interactionist view of second language acquisition, it was hypothesised that comprehension of a reading passage could be enhanced by online materials promoting interaction between students as they completed a multiple-choice reading comprehension exercise. Interaction was promoted: (a through pair work at a single computer and (b by providing Elaborative feedback in the form of hints about incorrect answers as a means of stimulating discussion about corrections. Students were randomly selected from upper and lower levels of English proficiency, as determined by the Kanda English Proficiency Test (Bonk & Ockey, 2003, to receive either Elaborative feedback or Knowledge of Correct Response feedback (which supplies the correct answers. Within these groups, some students worked in pairs and some alone. Quantitative results show that the interaction between Type of feedback and Manner of study (individual or pair work was statistically significant; students performed best on a follow-up comprehension exercise when in pairs and having been provided with Elaborative feedback. Furthermore, qualitative analysis of transcribed interactions also shows that Elaborative feedback was conducive to quality interaction.

    Black, Alice A. (Jill)

    Research has shown the presence of many Earth science misconceptions and conceptual difficulties that may impede concept understanding, and has also identified a number of categories of spatial ability. Although spatial ability has been linked to high performance in science, some researchers believe it has been overlooked in traditional education. Evidence exists that spatial ability can be improved. This correlational study investigated the relationship among Earth science conceptual understanding, three types of spatial ability, and psychological gender, a self-classification that reflects socially-accepted personality and gender traits. A test of Earth science concept understanding, the Earth Science Concepts (ESC) test, was developed and field tested from 2001 to 2003 in 15 sections of university classes. Criterion validity was .60, significant at the .01 level. Spearman/Brown reliability was .74 and Kuder/Richardson reliability was .63. The Purdue Visualization of Rotations (PVOR) (mental rotation), the Group Embedded Figures Test (GEFT) (spatial perception), the Differential Aptitude Test: Space Relations (DAT) (spatial visualization), and the Bem Inventory (BI) (psychological gender) were administered to 97 non-major university students enrolled in undergraduate science classes. Spearman correlations revealed moderately significant correlations at the .01 level between ESC scores and each of the three spatial ability test scores. Stepwise regression analysis indicated that PVOR scores were the best predictor of ESC scores, and showed that spatial ability scores accounted for 27% of the total variation in ESC scores. Spatial test scores were moderately or weakly correlated with each other. No significant correlations were found among BI scores and other test scores. Scantron difficulty analysis of ESC items produced difficulty ratings ranging from 33.04 to 96.43, indicating the percentage of students who answered incorrectly. Mean score on the ESC was 34

    Changes over the last decade in overt proficiency testing (OPT) regulations have been ostensibly directed at improving laboratory performance on patient samples. However, the overt (unblinded) format of the tests and regulatory penalties associated with incorrect values allow and encourage laboratorians to take extra precautions with OPT analytes. As a result OPT may measure optimal laboratory performance instead of the intended target of typical performance attained during routine patient testing. This study addresses this issue by evaluating medical mycology OPT and comparing its fungal specimen identification error rates to those obtained in a covert (blinded) proficiency testing (CPT) program. Identifications from 188 laboratories participating in the New York State mycology OPT from 1982 to 1994 were compared with the identifications of the same fungi recovered from patient specimens in 1989 and 1994 as part of the routine procedures of 88 of these laboratories. The consistency in the identification of OPT specimens was sufficient to make accurate predictions of OPT error rates. However, while the error rates in OPT and CPT were similar for Candida albicans, significantly higher error rates were found in CPT for Candida tropicalis, Candida glabrata, and other common pathogenic fungi. These differences may, in part, be due to OPT’s use of ideal organism representatives cultured under optimum growth conditions. This difference, as well as the organism-dependent error rate differences, reflects the limitations of OPT as a means of assessing the quality of routine laboratory performance in medical mycology.

    Full Text Available We compared Hindi-English bilinguals differing in their L2 fluency on a saccadic countermanding task which taps inhibitory control as well as monitoring. We particularly explored whether response inhibition and performance monitoring within the oculomotor domain are affected by language proficiency in bilinguals. There were two different oculomotor redirect tasks: Visually Guided Redirect (VGR task (Experiment1 and Memory Guided Redirect (MGR task (Experiment 2. In this task typically a target is presented to which subject must make saccade (No step trials, unless a new target appears on the other location after some delay from the first target onset (Step trials. On such trials participants are required to inhibit and cancel the saccade to the first instead program a saccade to the new target. Using trial switch reaction time (TSRT, which is the time taken to inhibit the initiated saccade to the first target, as a measure of response inhibition, and post-stop slowing as a measure of performance monitoring, we observed two important results. It was found that high proficiency bilinguals showed more post-stop slowing on the no-step trials as compared to the low proficiency bilinguals for both VGR and MGR. Secondly, high and low proficiency bilingual exhibited comparable TSRT in both VGR and MGR, showing no altering effect of language proficiency on the response inhibition in bilinguals. These results suggest that bilingualism impacts performance monitoring which is modulated by language proficiency if not the inhibitory control system. Higher fluency may lead to superior cognitive flexibility, and ability to adjust behaviour that facilitates attainment of cognitive goal. These findings are in consonance with other current studies that suggest a top-down effect of bilingualism on action control systems.

    2006-07-01

    Full Text Available The present study has attempted to determine weather there is any relationship between language learning strategies employed by language learners, and if so what relationship exists between them. Furthermore, it has tried to investigate what effective and useful strategies the learners employ while learning English as a foreign language correspondent with their proficiency levels. A simulated TOEFL (REA, 1993 test was initially administered to classify the learners into three classes of proficiency levels. Oxford‟s Strategy Inventory, SILL, (Oxford, 1990 was used to determine the frequency of the language learning strategies applied by learners. The results of this study provide confirmation of previous research findings concerning the direct relationship between language learning strategies and language proficiency level, and represent the types of the strategies adopted by advanced, intermediate and elementary language learners. The implications of this study are to suggest both the metacognitive compensatory strategies, the most frequent strategies employed by advanced learners be instructed to the language learners in order to upgrade their proficiency level.

  7. Proficiency testing as a basis for estimating uncertainty of measurement: application to forensic alcohol and toxicology quantitations.

    Science.gov (United States)

    Wallace, Jack

    2010-05-01

    While forensic laboratories will soon be required to estimate uncertainties of measurement for those quantitations reported to the end users of the information, the procedures for estimating this have been little discussed in the forensic literature. This article illustrates how proficiency test results provide the basis for estimating uncertainties in three instances: (i) For breath alcohol analyzers the interlaboratory precision is taken as a direct measure of uncertainty. This approach applies when the number of proficiency tests is small. (ii) For blood alcohol, the uncertainty is calculated from the differences between the laboratory's proficiency testing results and the mean quantitations determined by the participants; this approach applies when the laboratory has participated in a large number of tests. (iii) For toxicology, either of these approaches is useful for estimating comparability between laboratories, but not for estimating absolute accuracy. It is seen that data from proficiency tests enable estimates of uncertainty that are empirical, simple, thorough, and applicable to a wide range of concentrations.

    2011-12-01

    This study investigated newly qualified teachers' visions of science learning and teaching. The study also documented their preparation in an elementary science methods course. The research questions were: What educational and professional experiences influenced the instructor's visions of science learning and teaching? What visions of science learning and teaching were promoted in the participants' science methods course? What visions of science learning and teaching did these newly qualified teachers bring with them as they graduated from their teacher preparation program? How did these visions compare with those advocated by reform documents? Data sources included participants' assignments, weekly reflections, and multi-media portfolio finals. Semi-structured interviews provided the emic voice of participants, after graduation but before they had begun to teach. These data were interpreted via a combination of qualitative methodologies. Vignettes described class activities. Assertions supported by excerpts from participants' writings emerged from repeated review of their assignments. A case study of a typical participant characterized weekly reflections and final multi-media portfolio. Four strands of science proficiency articulated in a national reform document provided a framework for interpreting activities, assignments, and interview responses. Prior experiences that influenced design of the methods course included an inquiry-based undergraduate physics course, participation in a reform-based teacher preparation program, undergraduate and graduate inquiry-based science teaching methods courses, participation in a teacher research group, continued connection to the university as a beginning teacher, teaching in diverse Title 1 schools, service as the county and state elementary science specialist, participation in the Carnegie Academy for the Scholarship of Teaching and Learning, service on a National Research Council committee, and experience teaching a

    2015-07-01

    With the introduction of Fundamentals of Endoscopic Surgery, training methods in flexible endoscopy are being augmented with simulation-based curricula. The investment for virtual reality simulators warrants further research into its training advantage. Trainees were randomized into bedside or simulator training groups (BED vs SIM). SIM participated in a proficiency-based virtual reality curriculum. Trainees' endoscopic skills were rated using the Global Assessment of Gastrointestinal Endoscopic Skills (GAGES) in the patient care setting. The number of cases to reach 90 per cent of the maximum GAGES score and calculated costs of training were compared. Nineteen residents participated in the study. There was no difference in the average number of cases required to achieve 90 per cent of the maximum GAGES score for esophagogastroduodenoscopy, 13 (SIM) versus11 (BED) (P = 0.63), or colonoscopy 21 (SIM) versus 4 (BED) (P = 0.34). The average per case cost of training for esophagogastroduodenoscopy was $35.98 (SIM) versus $39.71 (BED) (P = 0.50), not including the depreciation costs associated with the simulator ($715.00 per resident over six years). Use of a simulator appeared to increase the cost of training without accelerating the learning curve or decreasing faculty time spent in instruction. The importance of simulation in endoscopy training will be predicated on more cost-effective simulators.

  4. Observed hierarchy of student proficiency with period, frequency, and angular frequency

    Full Text Available In the context of a generic harmonic oscillator, we investigated students’ accuracy in determining the period, frequency, and angular frequency from mathematical and graphical representations. In a series of studies including interviews, free response tests, and multiple choice tests developed in an iterative process, we assessed students in both algebra-based and calculus-based, traditionally instructed university-level introductory physics courses. Using the results, we categorized nine skills necessary for proficiency in determining period, frequency, and angular frequency. Overall results reveal that, postinstruction, proficiency is quite low: only about 20%–40% of students mastered most of the nine skills. Next, we used a semiquantitative, intuitive method to investigate the hierarchical structure of the nine skills. We also employed the more formal item tree analysis method to verify this structure and found that the skills form a multilevel, nonlinear hierarchy, with mastery of some skills being prerequisite for mastery in other skills. Finally, we implemented a targeted, 30-min group-work activity to improve proficiency in these skills and found a 1 standard deviation gain in accuracy. Overall, the results suggest that many students currently lack these essential skills, targeted practice may lead to required mastery, and that the observed hierarchical structure in the skills suggests that instruction should especially attend to the skills lower in the hierarchy.

    2009-01-01

    The IAEA helps the Member States' laboratories to maintain their readiness by coordination activities, by development of standardized methods for sample collection and analysis, and by conducting interlaboratory comparisons and proficiency tests as a tool for external quality control. The Chemistry Unit of the Physics, Chemistry and Instrumentation Laboratory in the International Atomic Energy Agency's Seibersdorf Laboratories in Austria, has the programmatic responsibility to support global radionuclide measurement systems. To fulfil this obligation and ensure a reliable worldwide, rapid and consistent response, the Chemistry Unit organises interlaboratory studies and proficiency tests. The Po-210 poisoning event which occurred in November 2006 brought into focus a number of issues, including the capacity of laboratories to rapidly and accurately determine this radionuclide in environmental samples. A number of requests were received from Member States to address this issue. Responding to these requests, the Chemistry Unit of the Physics, Chemistry and Instrumentation Laboratory in the Agency's Laboratories, conducted a world wide proficiency test on the determination of Po-210 in water. The aim was to gather information on the current state of practice for Po-210 measurements at various levels in aqueous samples. This report describes the methodology employed and the results obtained in this proficiency test

    2017-05-01

    Children learning English as an additional language (EAL) often experience lower academic attainment than monolingual peers. In this study, teachers provided ratings of English language proficiency and social, emotional, and behavioral functioning for 782 children with EAL and 6,485 monolingual children in reception year (ages 4-5). Academic attainment was assessed in reception and Year 2 (ages 6-7). Relative to monolingual peers with comparable English language proficiency, children with EAL displayed fewer social, emotional, and behavioral difficulties in reception, were equally likely to meet curriculum targets in reception, and were more likely to meet targets in Year 2. Academic attainment and social, emotional, and behavioral functioning in children with EAL are associated with English language proficiency at school entry. © 2016 The Authors.

    2012-01-01

    A large number of studies have demonstrated the bilinguals' advantage in cognitive control, and some researchers have explored the components of cognitive control. However, there are four gaps. ( 1 ) Most studies only examined one or two components of cognitive control. Few studies clearly defined cognitive control and systematically compared these components between non-proficient bilinguals and proficient bilinguals. (2) Compared with non-proficient bilinguals, do proficient bilinguals 'also have advantages in some components of cognitive control? ( 3 ) Is the influence of bilingualism on some components of cognitive control in bilingual children consistent with that in bilingual adults? (4) Are existing results suitable for Chinese-English bilinguals? The present study aims at answering these questions. Thirty non-proficient Chinese-English bilinguals and thirty proficient Chinese-English bilinguals were asked to administer the "faces task". All the participants were adults. Before the task, they finished the Raven Intelligence Test, culture, ethnic background and social economic status (SES) survey to eliminate the influence of some irrelevant variables. In the face task, the colored eyes could be looking either straight ahead or towards one of the two boxes, creating the straight eyes task and the gaze shift task. The participants should press the key on the same side as the box containing the asterisk if the eyes turned green and the opposite side if the eyes turned red. Inhibitory control was assessed by the difference in RT between trials in which the eyes looked towards the target and those in which the eyes looked away from the target in the gaze shift task. The results showed that the non-proficient Chinese-English bilinguals produced a larger cost than the proficient Chinese-English bilinguals, t(57) = 2. 107, p = . 040. Cognitive flexibility was assessed by the difference between mixed and single block presentations. The results showed that the non

    Prince, Joan Marie

    1999-12-01

    Over the past years, progress in Black academic achievement, particularly in the area of science, has generally slowed or ceased. According to the 1994 NAEP assessment, twelfth-grade Black students are performing at the level of White eighth-grade students in the discipline of science (Department of Education, 1996). These students, in their last year of required schooling, are about to graduate, yet they lag at least four years behind their white counterparts in science achievement. Despite the establishment and implementation of numerous science intervention programs, Black students still suffer from a disparate gap in standardized test score achievement. The purpose of this research is to investigate teachers' perceptions of the effectiveness of an urban sciences intervention tool that was designed to assist in narrowing the Black-White science academic achievement gap. Specifically, what factors affect teachers' personal sense of instructional efficacy, and how does this translate into their outcome expectancy for student academic success? A multiple-case, replicative design, grounded in descriptive theory, was selected for the study. Multiple sources of evidence were queried to provide robust findings. These sources included a validated health sciences self-efficacy instrument, an interview protocol, a classroom observation, and a review of archival material that included case study participants' personnel files and meeting minutes. A cross-comparative analytic approach was selected for interpretation (Yin, 1994). Findings indicate that teachers attribute the success or failure of educational intervention tools in closing the Black-White test score gap to a variety of internal and external factors. These factors included a perceived lack of both monetary and personal support by the school leadership, as well as a perceived lack of parental involvement which impacted negatively on student achievement patterns. The case study participants displayed a depressed

    Little is known about 2nd language development among young, low-income, language-minority children. This article examined the longitudinal English development of low-income, dual language learners (DLLs) in Miami (n = 18,532) from kindergarten through 5th grade. Growth curve modeling indicated that social skills, good behavior, Spanish (L1) competence in preschool, having a mother born in the United States, and attending larger schools with fewer DLLs were associated with higher initial levels of English proficiency in kindergarten and/or steeper growth over time. Survival analyses indicated that it took about 2 years for half of the sample to become proficient in English according to the school district's criterion. Higher initial proficiency in kindergarten, not receiving free/reduced lunch, not being Hispanic or Black, strong cognitive, language, and socioemotional skills at age 4, and maternal education were associated with faster attainment of English proficiency. It is important for teachers, parents, researchers, and policy makers to understand that DLL students come from diverse backgrounds and that poverty and other factors influence the speed of English language development for DLLs.

    Kim, Mi Ye; Lim, Ji Young; Chung, Grace H

    2012-12-01

    There is evidence that parent-child cohesion is a potentially influential factor in children's self-esteem and acculturation. However, no research to date has examined cohesion with parents as a potential pathway between Korean proficiency and self-esteem or acculturation among children from multicultural families. This study was done to address these limitations by examining whether and to what extent cohesion with parents mediated the effect of Korean proficiency on self-esteem and acculturation among children from multicultural families. Data were collected from a sample of 138 mothers and their children living in Seoul, Daegu, Kyungi province, and Kyungpook province. Multiple regression analysis was used to examine the relationships between the variables of interest. Mediation effects of cohesion with parents were tested by following the procedure recommended by Baron and Kenny (1986). Cohesion with parents partially mediated the relationship between Korean proficiency and self-esteem. For children's acculturation, the effect of Korean proficiency was partially mediated through father-child cohesion. Mother-child cohesion completely mediated the relationship between Korean proficiency and acculturation. These findings suggest that to help children from multicultural families experiencing difficulties with self-esteem or acculturation, it might be useful to develop programs that are aimed at strengthen cohesion with parents.

  14. The organizational effects of pubertal testosterone on sexual proficiency in adult male Syrian hamsters.

    De Lorme, Kayla C; Sisk, Cheryl L

    2016-10-15

    Social proficiency requires making appropriate behavioral adaptations as a result of social experience. For example, male rodents become sexually proficient with experience as demonstrated by a reduction in ectopic (misdirected) mounts, mount-to-intromission ratio, and latency to ejaculation. We previously found that over a series of timed tests with a receptive female, male hamsters deprived of testosterone specifically during puberty (NoT@P) have overall lower levels of sexual behavior and continue to display high levels of ectopic mounts, compared with males that experienced endogenous testosterone during puberty (T@P). These results suggested that pubertal testosterone programs sexual proficiency in adulthood, but because NoT@P males engaged in less sexual behavior than T@P males in these tests, the amount of sexual experience may have been insufficient to improve sexual proficiency. To more rigorously test the hypothesis that pubertal testosterone is necessary for social proficiency in adulthood, the present study compared the behavior of NoT@P and T@P males in a series of 4 trials with a 48-h interval between each trial. Sexual experience was equated by limiting each trial to 5 intromissions. Sexually-naïve males were either gonadectomized prepubertally (NoT@P) or in adulthood (T@P) and received subcutaneous testosterone capsules four weeks later. Two weeks after testosterone replacement, these groups and a group of adult gonad-intact controls began sexual behavior testing. We found that NoT@P males had more ectopic mounts/min across all four tests compared to gonad-intact and T@P males. Moreover, both gonad-intact and T@P males, but not NoT@P males, showed an increase in the number of mounts and intromissions/min between trials 1 and 3. Unexpectedly, both gonad-intact and T@P, but not NoT@P, males showed a decrease in sexual behaviors during trial 4. Thus, T@P males display multiple behavioral adaptations to sexual experience that are not observed in No

    Most medical schools in the United States use the National Board of Medical Examiners Subject Examinations as a method of at least partial assessment of student performance, yet there is still uncertainty of how well these examination scores correlate with clinical proficiency. Thus, we investigated which factors in a surgery clerkship curriculum have a positive effect on academic achievement on the National Board of Medical Examiners Subject Examination in Surgery. A retrospective analysis of 83 third-year medical students at our institution with 4 unique clinical experiences on the general surgery clerkship for the 2007-2008 academic year was conducted. Records of the United States Medical Licensing Examination Step 1 scores, National Board of Medical Examiners Subject Examination in Surgery scores, and essay examination scores for the groups were compared using 1-way analysis of variance testing. Rush University Medical Center, Chicago IL, an academic institution and tertiary care center. Our data demonstrated National Board of Medical Examiners Subject Examination in Surgery scores from the group with the heavier clinical loads and least time for self-study were statistically higher than the group with lighter clinical services and higher rated self-study time (p = 0.036). However, there was no statistical difference of National Board of Medical Examiners Subject Examination in Surgery scores between the groups with equal clinical loads (p = 0.751). Students experiencing higher clinical volumes on surgical services, but less self-study time demonstrated statistically higher academic performance on objective evaluation, suggesting clinical experience may be of higher value than self-study and reading.

    2016-06-01

    Understanding attitudes toward science and measuring them remain two major challenges for science teaching. This article reviews the concept of attitudes toward science and their measurement. It subsequently analyzes the psychometric properties of the Test of Science-Related Attitudes (TOSRA), such as its construct validity, its discriminant and concurrent validity, and its reliability. The evidence presented suggests that TOSRA, in its Spanish-adapted version, has adequate construct validity regarding its theoretical referents, as well as good indexes of reliability. In addition, it determines the attitudes toward science of secondary school students in Santiago de Chile (n = 664) and analyzes the sex variable as a differentiating factor in such attitudes. The analysis by sex revealed low-relevance gender difference. The results are contrasted with those obtained in English-speaking countries. This TOSRA sample showed good psychometric parameters for measuring and evaluating attitudes toward science, which can be used in classrooms of Spanish-speaking countries or with immigrant populations with limited English proficiency.

    Sargeant, Marcel Andre Almont

    Problem. Science education has long been a great concern in the United States, where less than one-third of the students perform at or above the proficient level. The purpose of this study was to investigate the status of the science program in a selected Union Conference of the Seventh-day Adventist school system. Specifically, this study investigated the perceptions of teachers and students regarding the extent to which the science program meets the criteria of the National Commission on Mathematics and Science Teaching for the 21st century and to what extent these criteria are related to academic performance as indicated by Iowa Test of Basic Skills (ITBS) science scores. Method. Two questionnaires designed by the researcher were used to get responses from 424 students in seventh and eighth grades and 68 teachers to see how this school system compares to the criteria of National Commission on Mathematics and Science Teaching for the 21 st century. Three classroom configurations were investigated in this study, namely: (a) multigrade, (b) two-grade, and (c) single-grade. Crosstabulation, one-way analysis of variance, Kruskal-Wallis test, and linear regression were used to analyze the four research questions of this study. Results. The single-grade classroom configuration received a better rating for the science criteria (p century. Conclusions. The differences in teaching practices explained the discrepancies in the three classroom configurations. Schools can therefore develop policies and strategies to improve the practices in the teaching and learning process in science education that were identified as being deficient by the criteria of National Commission on Mathematics and Science Teaching for the 21st century.

    2015-06-01

    The increase in nursing students for whom English is an additional language requires clinical facilitators to assess students' performance regarding clinical skills, nursing communication and English language. However, assessing language proficiency is a complex process that is often conflated with cultural norms and clinical skills, and facilitators may lack confidence in assessing English language. This paper discusses an evaluation of a set of guidelines developed in a large metropolitan Australian university to help clinical facilitators make decisions about students' English language proficiency. The study found that the guidelines were useful in helping facilitators assess English language. However, strategies to address identified language problems needed to be incorporated to enable the guidelines to also be used as a teaching tool. The study concludes that to be effective, such guidelines need embedding within a systematic approach that identifies and responds to students who may be underperforming due to a low level of English language proficiency.

  13. Functional activity and white matter microstructure reveal the independent effects of age of acquisition and proficiency on second-language learning.

    Nichols, Emily S; Joanisse, Marc F

    2016-12-01

    Two key factors govern how bilingual speakers neurally maintain two languages: the speakers' second language age of acquisition (AoA) and their subsequent proficiency. However, the relative roles of these two factors have been difficult to disentangle given that the two can be closely correlated, and most prior studies have examined the two factors in isolation. Here, we combine functional magnetic resonance imaging with diffusion tensor imaging to identify specific brain areas that are independently modulated by AoA and proficiency in second language speakers. First-language Mandarin Chinese speakers who are second language speakers of English were scanned as they performed a picture-word matching task in either language. In the same session we also acquired diffusion-weighted scans to assess white matter microstructure, along with behavioural measures of language proficiency prior to entering the scanner. Results reveal gray- and white-matter networks involving both the left and right hemisphere that independently vary as a function of a second-language speaker's AoA and proficiency, focused on the superior temporal gyrus, middle and inferior frontal gyrus, parahippocampal gyrus, and the basal ganglia. These results indicate that proficiency and AoA explain separate functional and structural networks in the bilingual brain, which we interpret as suggesting distinct types of plasticity for age-dependent effects (i.e., AoA) versus experience and/or predisposition (i.e., proficiency).

    Formal telestroke training for neurovascular fellows (NVFs) is necessary because of growing use of telestroke technologies in the management of acute ischemic stroke; yet, educational approaches and training benchmarks are not formalized. Time between telestroke consultant page and tissue-type plasminogen activator administration (page-to-needle time, PTNT) can provide an objective measure of proficiency. We compared PTNT between NVFs and neurovascular attendings (NVAs) and evaluated changes in PTNT with experience. We identified suspected acute ischemic stroke patients in our telestroke registry from July 2013 to December 2015 who received tissue-type plasminogen activator. Using multivariable quantile regression, we estimated the difference and 95% confidence interval in median PTNT between NVFs and NVAs. We also report the coefficient of change in PTNT over increasing number of telestroke consults. NVFs evaluated 53.7% of 618 tissue-type plasminogen activator cases over telestroke. NVAs had significantly shorter PTNT compared with NVFs, with a difference in median PTNT of -9 minutes (95% confidence interval, -12.3 to -5.7). This difference persisted when adjusted for relative tissue-type plasminogen activator contraindications. For each additional telestroke consult, PTNT decreased by 0.07 minutes for NVFs or NVAs ( P =0.02 and importance of integrating telestroke training into supervised neurovascular fellowships to increase proficiency prior to independent practice and suggest that PTNT can be a benchmark for tracking proficiency. © 2017 American Heart Association, Inc.

    Proficiency-based virtual reality (VR) training curricula improve intraoperative performance, but have not been developed for laparoscopic appendicectomy (LA). This study aimed to develop an evidence-based training curriculum for LA. A total of 10 experienced (>50 LAs), eight intermediate (10-30 LAs) and 20 inexperienced (<10 LAs) operators performed guided and unguided LA tasks on a high-fidelity VR simulator using internationally relevant techniques. The ability to differentiate levels of experience (construct validity) was measured using simulator-derived metrics. Learning curves were analysed. Proficiency benchmarks were defined by the performance of the experienced group. Intermediate and experienced participants completed a questionnaire to evaluate the realism (face validity) and relevance (content validity). Of 18 surgeons, 16 (89%) considered the VR model to be visually realistic and 17 (95%) believed that it was representative of actual practice. All 'guided' modules demonstrated construct validity (P < 0.05), with learning curves that plateaued between sessions 6 and 9 (P < 0.01). When comparing inexperienced to intermediates to experienced, the 'unguided' LA module demonstrated construct validity for economy of motion (5.00 versus 7.17 versus 7.84, respectively; P < 0.01) and task time (864.5 s versus 477.2 s versus 352.1 s, respectively, P < 0.01). Construct validity was also confirmed for number of movements, path length and idle time. Validated modules were used for curriculum construction, with proficiency benchmarks used as performance goals. A VR LA model was realistic and representative of actual practice and was validated as a training and assessment tool. Consequently, the first evidence-based internationally applicable training curriculum for LA was constructed, which facilitates skill acquisition to proficiency. © 2017 Royal Australasian College of Surgeons.

    2013-02-01

    The number of households in the United States that are not proficient in the English language is growing and presenting a challenge to the health care system. Over nineteen percent of the US population speak a language other than English in the home. This increase in language discordance generates a greater need to find and implement accommodations in the clinical setting to insure accurate and efficient diagnosis and treatment as well as provide for patient safety. The purpose of this study is to determine the percentage of patients accessing the chiropractic college teaching clinics who are not proficient in the English language and to what extent the colleges provide accommodations for that language disparity. The clinic directors and deans of the Association of Chiropractic Colleges were surveyed via an on-line survey engine. The survey queried the percentage of the patient population that is not English language proficient, the accommodations the college currently has in place, if the college has a language specific consent to treat document and if the college has a written policy concerning patients without English proficiency. Fifty percent of the contacted chiropractic colleges responded to the survey. In the respondent college clinics 16.5% of the patient population is not proficient in English, with over 75% speaking Spanish. All but one of the respondents provide some level of accommodation for the language non-concordance. Forty five percent of the responding colleges employ a language specific consent to treat form. The implementation of accommodations and the use of a language specific consent to treat form is more prevalent at colleges with a higher percentage of non-English speaking patients. The percentage of patients with limited English proficiency accessing services at the teaching clinics of the chiropractic colleges mirrors the numbers in the general population. There is a wide disparity in the accommodations that the individual colleges make

    The Faculty of Medicine and Health Sciences (FMHS), United Arab Emirates (UAE) University is in a unique position to explore issues related to English language proficiency and medical student performance. All students entering the FMHS have English as a second language. This study focused on the issues of students' proficiency in English as measured by the TOEFL test, student background factors and interaction in problem-based learning (PBL) groups. Using a modification of Bales Interaction Process Analysis, four problem-based learning groups were observed over four thematic units, to measure the degree of student interaction within PBL groups and to compare this to individual TOEFL scores and key background variables. The students' contributions correlated highly with TOEFL test results in the giving of information (range r = 0.67-0.74). The female students adhered to interacting in English during group sessions, whereas the male students were more likely to revert to using Arabic in elaborating unclear phenomena (p TOEFL scores for the male students, but not for female students. Multivariate analysis was undertaken to analyse the relative contribution of the TOEFL, parental education and years of studying in English. The best predictor of students' contributions in PBL groups was identified as TOEFL scores. The study demonstrates the importance of facilitating a locally acceptable level of English proficiency prior to admission to the FMHS. However, it also highlights the importance of not focusing only on English proficiency but paying attention to additional factors in facilitating medical students in maximizing benefits from interactions in PBL settings.

    The study objective was to examine the effects of two conceptually related constructs, self-compassion and dispositional mindfulness, on executive function (EF) proficiency among early adolescents. Executive function refers to a set of psychological processes governing emotional regulation, organization, and planning. While the benefits of positive psychology appear evident for mental health and wellness, little is known about the etiological relationship between dispositional mindfulness and self-compassion in their associations with EF. Two hundred and ten early adolescents attending middle school (age M=12.5 years; SD=0.5; 21% Hispanic, 18% Mixed/bi-racial, 47% White, and 9% Other/Missing; 37.1% on free lunch program) self-reported levels of dispositional mindfulness (Mindful Attention Awareness Scale; MAAS), self-compassion (Self-Compassion Scale; SCS; self-judgment and self-kindness domains), and EF proficiency (Behavior Rating Inventory of Executive Function; BRIEF-SR). A sequential linear regression stepwise approach was taken entering the independent variables as separate models in the following order: self-kindness, self-judgement, and dispositional mindfulness. All models controlled for participant age and sex. SCS self-kindness was not associated with EF proficiency, but SCS self-judgment (reverse-coded) contributed to the variance in EF (β=0.40, p mindfulness appears to outweigh that of specific self-compassion domains, when independent of contemplative training.

  12. Effects of random study checks and guided notes study cards on middle school special education students' notetaking accuracy and science vocabulary quiz scores

    Wood, Charles L.

    Federal legislation mandates that all students with disabilities have meaningful access to the general education curriculum and that students with and without disabilities be held equally accountable to the same academic standards (IDEIA, 2004; NCLB, 2001). Many students with disabilities, however, perform poorly in academic content courses, especially at the middle and secondary school levels. Previous research has reported increased notetaking accuracy and quiz scores over lecture content when students completed guided notes compared to taking their own notes. This study evaluated the effects of a pre-quiz review procedure and specially formatted guided notes on middle school special education students' learning of science vocabulary. This study compared the effects of three experimental conditions. (a) Own Notes (ON), (b) Own Notes+Random Study Checks (ON+RSC), and (c) Guided Notes Study Cards+Random Study Checks (GNSC+RSC) on each student's accuracy of notes, next-day quiz scores, and review quiz scores. Each session, the teacher presented 12 science vocabulary terms and definitions during a lecture and students took notes. The students were given 5 minutes to study their notes at the end of each session and were reminded to study their notes at home and in study hall period. In the ON condition students took notes on a sheet of paper with numbered lines from 1 to 12. Just before each next-day quiz in the ON+RSC condition students used write-on response cards to answer two teacher-posed questions over randomly selected vocabulary terms from the previous day's lecture. If the answer on a randomly selected student's response card was correct, that student earned a lottery ticket for inexpensive prizes and a quiz bonus point for herself and each classmate. In the GNSC+RSC condition students took notes on specially formatted guided notes that after the lecture they cut into a set of flashcards that could used for study. The students' mean notetaking accuracy was 75

    The promise of PARP-inhibitors(PARPis) in the management of epithelial ovarian cancer(EOC) is tempered by the fact that approximately 50% of patients with homologous recombination (HR)-proficient tumors do not respond well to these agents. Combination of PARPis with agents that inhibit HR may represent an effective strategy to enhance their activity in HR-proficient tumors. Using a bioinformatics approach, we identified that heat shock protein 90 inhibitors(HSP90i) may suppress HR and thus revert HR-proficient to HR-deficient tumors. Analysis of publicly available gene expression data showed that exposure of HR-proficient breast cancer cell lines to HSP90i 17-AAG(17-allylamino-17-demethoxygeldanamycin) downregulated HR, ATM and Fanconi Anemia pathways. In HR-proficient EOC cells, 17-AAG suppressed HR as assessed using the RAD51 foci formation assay and this was further confirmed using the Direct Repeat-GFP reporter assay. Furthermore, 17-AAG downregulated BRCA1 and/or RAD51 protein levels, and induced significantly more γH2AX activation in combination with olaparib compared to olaparib alone. Finally, sublethal concentrations of 17-AAG sensitized HR-proficient EOC lines to olaparib and carboplatin but did not affect sensitivity of the HR-deficient OVCAR8 line arguing that the 17-AAG mediated sensitization is dependent on suppression of HR. These results provide a preclinical rationale for using a combination of olaparib/17-AAG in HR-proficient EOC.

    Increasing the retention of STEM (science, technology, engineering, and mathematics) majors has recently emerged as a national priority in undergraduate education. Since poor performance in large introductory science and math courses is one significant factor in STEM dropout, early detection of struggling students is needed. Technology-supported "early warning systems" (EWSs) are being developed to meet these needs. Our study explores the utility of two commonly collected data sources—pre-course concept inventory scores and longitudinal clicker scores—for use in EWS, specifically, in determining the time points at which robust predictions of student success can first be established. The pre-course diagnostic assessments, administered to 287 students, included two concept inventories and one attitude assessment. Clicker question scores were also obtained for each of the 37 class sessions. Additionally, student characteristics (sex, ethnicity, and English facility) were gathered in a survey. Our analyses revealed that all variables were predictive of final grades. The correlation of the first 3 weeks of clicker scores with final grades was 0.53, suggesting that this set of variables could be used in an EWS starting at the third week. We also used group-based trajectory models to assess whether trajectory patterns were homogeneous in the class. The trajectory analysis identified three distinct clicker performance patterns that were also significant predictors of final grade. Trajectory analyses of clicker scores, student characteristics, and pre-course diagnostic assessment appear to be valuable data sources for EWS, although further studies in a diversity of instructional contexts are warranted.

    Proficiency assessments are important elements in quality control for diagnostic laboratories. Traditionally, proficiency testing for polymerase chain reaction (PCR)-based assays has involved the use of clinical samples, samples "spiked" with live agents or DNA plasmids. Because of government regulations and biosecurity concerns, distribution of live high-consequence pathogens of livestock and poultry, such as avian influenza, is not possible, and DNA plasmids are not technically suitable for evaluating RNA virus detection. Therefore, a proficiency testing panel using whole avian influenza in a diluent containing a phenolic disinfectant that inactivates the virus while preserving the RNA for at least 8 weeks at -70 C was developed and used in a multicenter proficiency assessment for a type A influenza real-time reverse transcriptase (RT)-PCR test. The test, which was highly standardized, except for variation in the real-time RT-PCR equipment used, was shown to be highly reproducible by proficiency testing in 12 laboratories in the United States, Canada, and Hong Kong. Variation in cycle threshold values among 35 data sets and 490 samples was minimal (CV = 5.19%), and sample identifications were highly accurate (96.7% correct identifications) regardless of real-time PCR instrumentation.

    2002-01-01

    Full Text Available Several states have recently faced ballot initiatives that propose to functionally eliminate bilingual education in favor of English-only approaches. Proponents of these initiatives have argued an overall rise in standardized achievement scores of California's limited English proficient (LEP students is largely due to the implementation of English immersion programs mandated by Proposition 227 in 1998, hence, they claim Exito en California (Success in California. However, many such arguments presented in the media were based on flawed summaries of these data. We first discuss the background, media coverage, and previous research associated with California's Proposition 227. We then present a series of validity concerns regarding use of Stanford-9 achievement data to address policy for educating LEP students; these concerns include the language of the test, alternative explanations, sample selection, and data analysis decisions. Finally, we present a comprehensive summary of scaled-score achievement means and trajectories for California's LEP and non-LEP students for 1998-2000. Our analyses indicate that although scores have risen overall, the achievement gap between LEP and EP students does not appear to be narrowing.

    Full Text Available This study aimed at investigating the relationship between types of dictionaries used and lexical proficiency in writing. Eighty TOEFL students took part in responding to two Questionnaires collecting information about their dictionary type preferences and habits of dictionary use, along with an interview for further in-depth responses. They were also asked to write a composition to be evaluated on their lexical proficiency. According to the results, the most frequently used dictionary type was Bilingual (E-P Desk Dictionary (BDD and the least favored dictionaries were Bilingual (P-E Desk Dictionary (BDD2 and Bilingual (P-E Mobile Dictionary (BMD. Referring to dictionaries in search of meaning during reading-writing, and after speaking-listening were the most common habits of students. Additionally, a significant relationship between the type of dictionary and lexical proficiency in participant’s writing was found. There was also a correlation between skill in dictionary use and lexical proficiency in writing. These finding entail some pedagogical benefits to enhance learners’ lexical competence by modifying the type of learners’ preferred dictionary and their habits in dictionary use.

  7. Cultural politics: Linguistic identity and its role as gatekeeper in the science classroom

    Science.gov (United States)

    Hilton-Brown, Bryan Anthony

    This dissertation investigated how participation in the cultural practices of science classrooms creates intrapersonal conflict for ethnic minority students. Grounded in research perspectives of cultural anthropology, sociocultural studies of science education, and critical pedagogy, this study examined the cultural tensions encountered by minority students as they assimilate into the culture of the science classroom. Classroom interaction was viewed from the perspective of instructional congruence---the active incorporation of students' culture into science pedagogy. Ogbu's notion of "oppositional identity", Fordham's "fictive kinship", Bahktin's "antidialogics", and Freire's "critical consciousness" were brought together to examine how members of marginalized cultures develop non-normative behaviors as a means of cultural resistance. Choice of genre for public discourse was seen as a political act, representing students' own cultural affiliations. Conducted in a diverse Southern Californian high school with an annual population of over 3,900 students, this study merged ethnographic research, action research, and sociolinguistic discourse analysis. Post hoc analysis of videotaped classroom activities, focus group interviews, and samples of student work revealed students' discursive behavior to shift as a product of the context of their discursive exchanges. In whole class discussions students explained their understanding of complex phenomena to classmates, while in small group discussions they favored brief exchanges of group data. Four domains of discursive identities were identified: Opposition Status, Maintenance Status, Incorporation Status, and Proficiency Status. Students demonstrating Opposition Status avoided use of science discourse. Those students who demonstrated Maintenance Status were committed to maintaining their own discursive behavior. Incorporation Status students were characterized by an active attempt to incorporate science discourse into

    Course-based undergraduate research is known to improve science, technology, engineering, and mathematics student achievement. We tested "The Small World Initiative, a Citizen-Science Project to Crowdsource Novel Antibiotic Discovery" to see if it also improved student performance and the critical thinking of non-science majors in Introductory Biology at Florida Atlantic University (a large, public, minority-dominant institution) in academic year 2014-15. California Critical Thinking Skills Test pre- and posttests were offered to both Small World Initiative (SWI) and control lab students for formative amounts of extra credit. SWI lab students earned significantly higher lecture grades than control lab students, had significantly fewer lecture grades of D+ or lower, and had significantly higher critical thinking posttest total scores than control students. Lastly, more SWI students were engaged while taking critical thinking tests. These results support the hypothesis that utilizing independent course-based undergraduate science research improves student achievement even in nonscience students.

  9. Analysis of English language learner performance on the biology Massachusetts comprehensive assessment system: The impact of english proficiency, first language characteristics, and late-entry ELL status

    Mitchell, Mary A.

    This study analyzed English language learner (ELL) performance on the June 2012 Biology MCAS, namely on item attributes of domain, cognitive skill, and linguistic complexity. It examined the impact of English proficiency, Latinate first language, first language orthography, and late-entry ELL status. The results indicated that English proficiency was a strong predictor of performance and that ELLs at higher levels of English proficiency overwhelmingly passed. The results further indicated that English proficiency introduced a construct-irrelevant variance on the Biology MCAS and raised validity issues for using this assessment at lower levels of English proficiency. This study also found that ELLs with a Latinate first language consistently had statistically significant lower performance. Late-entry ELL status did not predict Biology MCAS performance.

    A proficiency test (PT) exercise was offered by the International Atomic Energy Agency (IAEA) for major, minor and trace elements in Chinese ceramic reference material (IAEA-CU-2006-06). Neutron activation analysis (NAA) laboratory at PINSTECH, Pakistan participated in the exercise and submitted the results for 28 elements. The aim of participation was to develop a suitable methodology for accurate measurement of as many elements as possible in ceramic material using a low power reactor (PARR-2) as this would help future investigation in a project on the authenticity of art objects, for provenance, conservation and management of ancient cultural heritage of the country. After receiving the final report of the PT exercise, a critical review of our data and final scoring of each element is made to check the suitability of our methodology and reliability of the acquired data. Most of the reported results passed different statistical evaluation criterion such as relative bias, z-score and u-scores and ratio of our results and IAEA target values. One element (Yb) falls in the unacceptable range of relative bias and z-scores. Hf and Tb showed slightly high z-scores within the questionable range. Ho, Mo and Sn were determined during this study but their results were not submitted to the IAEA. The confidence of accuracy observed for most of the elements in ceramic material has made it mandatory to report their results as information values. (author)

    Fonzi, C E; Clausen, J L; Mahoney, J

    1993-03-01

    We prospectively determined the frequency of aberrant vials of fluorocarbon/buffer used for proficiency testing of measurements of pH, PCO2, and PO2, using 20 duplicate vials from 12 lots of fluorocarbon/buffer and two arterial blood gas analyzers in eight reference laboratories. We defined aberrant vials as vials for which both duplicate measurements differed from the mean value of repeated measurements for the specific instrument (for each lot of testing materials) by > 0.04 for pH, > 10% of the mean or 3.0 mm Hg, whichever was greater, for PCO2; or > 10% of the mean or 6 mm Hg, whichever was greater, for PO2. Four of 1620 vials (0.25%) were aberrant, all based on PO2 measurements (range of mean values: pH, 7.181-7.631; PCO2, 12.7-65.9; PO2, 32.5-150.1) were 0.0055 for pH, 0.67 mm Hg for PCO2, and 1.65 mm Hg for PO2. Deliberate contamination of the fluorocarbon emulsion with room air, as might occur during sampling from the vial, indicated that only minor increases in PO2 (e.g., 1.0 mm Hg at PO2 of 56 mm Hg) occur when samples are aspirated. Larger increases in PO2 (mean 7.1 mm Hg at a PO2 of 66 mm Hg) occurred when the syringe samples were contaminated with room air. We conclude that isolated aberrant measurements of PO2 in blood gas proficiency testing attributable to vial contents can occur, but the frequency is very low.

    Ebrahim Azimi Mohammad Abadi

    2013-05-01

    Full Text Available Vocabulary learning is incredibly noteworthy to English language acquisition. It is unfeasible for a learner to communicate without the required vocabulary. In high education levels, learners are habitually forced to become autonomous and make conscious effort to learn vocabulary outside of the classroom. Consequently, the autonomy of the learners plays an important role in developing and enhancing their vocabulary. Learner autonomy is a huge assistance for learners in vocabulary learning since it provides the learners with numerous diverse privileges such as independency from teacher. The researcher investigated whether there is any statistically significant relationship between learner autonomy and vocabulary learning strategies use in Iranian EFL learners with different language proficiency levels. To meet the above purpose, a total number of 190 male and female EFL learners participated in this study. The methodology underlying this study was quantitative (thorough the administration of two questionnaires and two language proficiency test – TOEFL for advanced group, and Nelson for intermediate level. The quantitative data was analyzed using a set of correlational analysis revealing a significant positive correlation between learner autonomy and vocabulary learning strategies use in high proficient group, and a significant positive relationship between these two constructs in low proficient group, however not as strong as in the advanced group.

    Routine diagnosis of animal trichinellosis for food safety and trade relies on a method of artificial digestion to free Trichinella muscle larvae from meat for subsequent identification by microscopy. As part of a quality control system, the French National Reference Laboratory (NRL) initiated ring trials to determine the sensitivity of the test performed in the 72 routine diagnostic laboratories in France. A method was devised to obtain calibrated meat samples containing known numbers of capsules with Trichinella spiralis muscle larvae. This method was based on an incomplete artificial digestion of Trichinella-infected mice carcasses to allow the collection of intact Trichinella capsules. Capsules were placed into a meatball of 100 +/- 2 g of pork and horsemeat to produce proficiency samples. Three categories of samples were prepared: small (3 to 5 capsules), medium (7 to 10), and large (12 to 15). The sensitivity was expressed as the percentage of muscle larvae recovered from each proficiency sample. Reproducibility was tested with ring trials organized between two NRLs (France and Canada), and a reference sensitivity of 84.9% was established. National ring trials were then organized in France, with the 72 routine diagnostic laboratories each receiving four proficiency samples per session. After five sessions, an improvement in the digest test sensitivity was observed. Results at the fifth session indicated sensitivities of 78.60% +/- 23.70%, 81.19% +/- 19.59%, and 80.52% +/- 14.71% muscle larvae for small, medium, and large samples, respectively. This study supports the use of proficiency samples to accurately evaluate the performance of routine diagnostic laboratories that conduct digestion tests for animal trichinellosis diagnosis.

    This study aims to construct a mathematical model of the relationship between a student's Language Learning Strategy usage and English Language proficiency. Fifty-six pre-university students of University Malaysia Sabah participated in this study. A self-report questionnaire called the Strategy Inventory for Language Learning was administered to them to measure their language learning strategy preferences before they sat for the Malaysian University English Test (MUET), the results of which were utilised to measure their English language proficiency. We attempted the model assessment specific to Multiple Linear Regression Analysis subject to variable selection using Stepwise regression. We conducted various assessments to the model obtained, including the Global F-test, Root Mean Square Error and R-squared. The model obtained suggests that not all language learning strategies should be included in the model in an attempt to predict Language Proficiency.

  3. Worldwide Open Proficiency Test: Determination of Natural and Artificial Radionuclides in Moss-Soil and Water IAEA-CU-2009-03

    International Nuclear Information System (INIS)

    2012-01-01

    Reliable determination of natural and artificial radionuclides in environmental samples is necessary to comply with radiation protection and environmental regulations. The IAEA assists Member State laboratories in maintaining and improving their readiness by producing reference materials, by developing standardized analytical methods, and by conducting interlaboratory comparisons and proficiency tests as tools for quality control. To fulfil this obligation and ensure a reliable, worldwide, rapid and consistent response, the IAEA Terrestrial Environment Laboratory in Seibersdorf, Austria, organizes interlaboratory comparisons and proficiency tests. This summary report presents the results of the worldwide proficiency test IAEA-CU-2009- 03 on the determination of natural and artificial radionuclides in moss-soil and spiked water. The methodologies, data evaluation approach, summary evaluation of each nuclide and individual evaluation reports for each laboratory are also described. This proficiency test was designed to identify analytical problems, to support Member State laboratories to improve the quality of their analytical results and maintain their accreditation, and to provide a regular forum for discussion and technology transfer in this area. The number of samples, their matrix interferences and the concentration levels of the analytes were designed in a way that enables identification of potential analytical problems.

    Full Text Available This retrospective study was carried out to assess the correlation between admi-ssion criteria to health science colleges, namely, final high school grade and Saudi National Apti-tude and Achievement exams, and early academic performance in these colleges. The study inclu-ded 91 male students studying in the two-year pre-professional program at the King Saud bin Abdulaziz University for Health Sciences (KSAU-HS, Riyadh, Saudi Arabia. Records of these students were used to extract relevant information and their academic performance (based on the grade point average achieved at the end of the first semester of the pre-professional program, which were analytically studied. Pearson correlation coefficient was used to assess the associa-tions between the different scores. SPSS statistical program (version 12.0 was used for data ana-lyses. We found a strong correlation between the academic performance and the Achievement Exam, Aptitude Exam and high school final grade, with Pearson Correlation Coefficients of 0.96, 0.93, 0.87, respectively. The Saudi National Achievement Exam showed the most significant correla-tion. Our results indicate that academic performance showed good correlation with the admission criteria used, namely final high school grade, Saudi National Aptitude and Achievement Exams.

  5. Differential Item Functioning (DIF) among Spanish-Speaking English Language Learners (ELLs) in State Science Tests

    Science.gov (United States)

    Ilich, Maria O.

    Psychometricians and test developers evaluate standardized tests for potential bias against groups of test-takers by using differential item functioning (DIF). English language learners (ELLs) are a diverse group of students whose native language is not English. While they are still learning the English language, they must take their standardized tests for their school subjects, including science, in English. In this study, linguistic complexity was examined as a possible source of DIF that may result in test scores that confound science knowledge with a lack of English proficiency among ELLs. Two years of fifth-grade state science tests were analyzed for evidence of DIF using two DIF methods, Simultaneous Item Bias Test (SIBTest) and logistic regression. The tests presented a unique challenge in that the test items were grouped together into testlets---groups of items referring to a scientific scenario to measure knowledge of different science content or skills. Very large samples of 10, 256 students in 2006 and 13,571 students in 2007 were examined. Half of each sample was composed of Spanish-speaking ELLs; the balance was comprised of native English speakers. The two DIF methods were in agreement about the items that favored non-ELLs and the items that favored ELLs. Logistic regression effect sizes were all negligible, while SIBTest flagged items with low to high DIF. A decrease in socioeconomic status and Spanish-speaking ELL diversity may have led to inconsistent SIBTest effect sizes for items used in both testing years. The DIF results for the testlets suggested that ELLs lacked sufficient opportunity to learn science content. The DIF results further suggest that those constructed response test items requiring the student to draw a conclusion about a scientific investigation or to plan a new investigation tended to favor ELLs.

    Reciprocity (total applied fluence produces the same response, regardless of the fluence rate) for the lethal effects caused by 365 and 254 nm ultraviolet light (UV) was studied for repair-proficient and -deficient Escherichia coli strains. In the repair-proficient strain, E. coli WP2 uvr A + recA + , reciprocity after 365 nm UV was only observed at fluence rates of about 750 Wm -2 and above. Below this rate, the cells became increasingly sensitive as the fluence rate was decreased. Similar lack of reciprocity was obtained whether the cells were exposed at 0 or 25 0 C. The double repair-defective mutant, E. coli WP100 uvr A recA, showed complete reciprocity after 365 nm UV over the same range of fluence rates measured for the repair-proficient strain. For 254 nm UV, complete reciprocity occurred in both strains over a range of fluence rates differing by an order of magnitude. (author)

    High caseworker turnover has been identified as a factor in the poor outcomes of child welfare services. However, almost no empirical research has examined the relationship between caseworker turnover and youth outcomes in child welfare systems and there is an important knowledge gap regarding whether, and how, caseworker turnover relates to outcomes for youth. We hypothesized that the effects of caseworker turnover are moderated by organizational culture such that reduced caseworker turnover is only associated with improved youth outcomes in organizations with proficient cultures. The study applied hierarchical linear models (HLM) analysis to the second National Survey of Child and Adolescent Well-being (NSCAW II) with a U.S. nationwide sample of 2,346 youth aged 1.5- to 18-years-old and 1,544 caseworkers in 73 child welfare agencies. Proficient organizational culture was measured by caseworkers' responses to the Organizational Social Context (OSC) measure; staff turnover was reported by the agencies' directors; and youth outcomes were measured as total problems in psychosocial functioning with the Child Behavior Checklist (CBCL) completed by the youths' caregivers at intake and at 18 month follow-up. The association between caseworker turnover and youth outcomes was moderated by organizational culture. Youth outcomes were improved with lower staff turnover in proficient organizational cultures and the best outcomes occurred in organizations with low turnover and high proficiency. To be successful, efforts to improve child welfare services by lowering staff turnover must also create proficient cultures that expect caseworkers to be competent and responsive to the needs of the youth and families they serve.

    Thus, key computational medicinal chemistry methods like molecular dynamics can be used to decipher protein flexibility and to obtain stable models for docking and scoring in food-related studies, and virtual screening is increasingly being applied to identify molecules with potential to act as endocrine disruptors, food mycotoxins, and new nutraceuticals [3,4,5]. All of these methods and simulations are based on protein-ligand interaction phenomena, and represent the basis for any subsequent modification of the targeted receptor's or enzyme's physiological activity. We describe here the energetics of binding of biological complexes, providing a survey of the most common and successful algorithms used in evaluating these energetics, and we report case studies in which computational techniques have been applied to food science issues. In particular, we explore a handful of studies involving the estrogen receptors for which we have a long-term interest.

    Full Text Available Effective implementation of Information and Communication Technologies (ICT plays an important role in school education, especially in a developing country like India, to improve the quality of education. School teachers’ lack of confidence and motivation for using ICT is one of the major barriers of its implementation in schools. These barriers can be either non-manipulative (i.e. which cannot be changed or manipulative (i.e. which can be changed with the help of school/government policies. This paper studies the impact of non-manipulative and manipulative teachers’ factors on their perceived proficiency in using ICT in the classrooms. It uses the primary data of 515 school teachers from the Maharashtra region of India teaching at high-school level (8th grade to 12th grade. The study concludes that both non-manipulative as well as manipulative teachers’ factors are important in affecting teachers’ perception regarding their own proficiency in using ICT in the classrooms. The study also provides some suggestions to improve the perception by changing some manipulative factors.

    The INPO task analysis process, as well as that of many utilities, is based on the approach used by the US Navy. This is undoubtedly due to the Navy nuclear background of many of those involved in introducing the systems approach to training to the nuclear power industry. This report outlines an approach, used by a major North-Central utility, which includes a process developed by the Air Force. Air Force task analysis and instructional system development includes the use of a proficiency code. The code includes consideration of three types of learning - task performance, task knowledge, and subject knowledge - and four levels of competence for each. The use of this classification system facilitates the identification of desired competency levels at the completion of formal training in the classroom and lab, and of informal training on the job. By using the Air Force's proficiency code. The utility's program developers were able to develop generic training for its main training facility and site-specific training at its nuclear plants, using the most efficiency and cost-effective training methods

    2017-10-01

    Full Text Available The study tends to explore the possible reforms to raise the proficiency level of the adult English as Foreign Language (EFL learners. With this end in view, it investigates non-native EFL teachers’ beliefs in relation to adult learners’ beliefs in teaching grammar to university students in the Saudi Arabian EFL context. It finds out the harmony and disharmony between the teachers at the giving end and the taught at the receiving end to create a culture of awareness and to build a better teaching-learning environment. The study tries to fill the existing research gap as no previous research has tried to find out the solution to the problem from this angle. The main data collection tools are two five-point Likert-scale questionnaires, administered to 70 non-native EFL teachers and their 80 adult students. Teachers and learners have been selected based on stratified random sampling. Quantitative data have been analyzed using the statistical package for social sciences (SPSS. The major findings of the study are that there is discrepancy in the grammar teaching beliefs of the EFL teachers and the taught and there is a communication gap between them which result into low English proficiency level of the EFL adult learners.  Eventually, pedagogical implications of the lack of harmony between the teachers’ teaching creeds and the learners’ learning demands/expectations are provided for effective grammar teaching and better EFL classroom environment. The study recommends a better communicative harmony in both the stakeholders to bring reforms in adult education in EFL context.

    Background: In recent research, affective learning environments and affective support have been receiving increasing attention for their roles in stimulating students' learning outcomes. Despite its raising importance, little is known about affective support in educational contexts in developing countries. Moreover, international student assessment programmes (e.g. PISA and TIMSS) reveal poor science proficiency of students in most of those countries, which provokes the question of how to make positive changes in students' perspectives and attitudes in science.

    Although brachytherapy increases the local control rate for cervical cancer, there has been a progressive decline in its use. Furthermore, the training among residency programs for gynecologic brachytherapy varies considerably, with some residents receiving little to no training. This trend is especially concerning given the association between poor applicator placement and decline in local control. Considering the success of proficiency-based training in other procedural specialties, we developed and implemented a proficiency-based cervical brachytherapy training curriculum for our residents. Each resident placed tandem and ovoid applicators with attending guidance and again alone 2 weeks later using a pelvic model that was modified to allow for cervical brachytherapy. Plain films were taken of the pelvic model, and applicator placement quality was evaluated. Other evaluated metrics included retention of key procedural details, the time taken for each procedure and presession and postsession surveys to assess confidence. During the initial session, residents on average met 4.5 of 5 placement criteria, which improved to 5 the second session. On average, residents were able to remember 7.6 of the 8 key procedural steps. Execution time decreased by an average of 10.5%. Resident confidence with the procedure improved dramatically, from 2.6 to 4.6 of 5. Residents who had previously never performed a tandem and ovoid procedure showed greater improvements in these criteria than those who had. All residents strongly agreed that the training was helpful and wanted to participate again the following year. Residents participating in this simulation training had measurable improvements in the time to perform the procedure, applicator placement quality, and confidence. This curriculum is easy to implement and is of great value for training residents, and would be particularly beneficial in programs with low volume of cervical brachytherapy cases. Simulation programs could
