AN ASSESSMENT OF THE CONTENT OF MEDICAL PRACTICE IN THE UNITED STATES: PROFILES OF PHYSICIANS IN FIVE SPECIALITIES     

Roger A. Girard  Stephen E. Radecki  Robert C. Mendenhall  Stephen Abrahamson  John S. Lloyd 《Assessment & Evaluation in Higher Education》1982,7(3):269-288

The University of Southern California has conducted a series of 24 surveys of the professional activities of physicians and surgeons in the United States. The surveys encompass more than 10,000 respondents representing 65.8% of all practising physicians in the United States and its territories. Using a specially‐developed “log‐diary” recording instrument, these physicians reported data on the care they provided during hundreds of thousands of encounters with their patients. This article provides an exposition of the study's unique methodology, presents illustratative data for 5 of the 24 specialities surveyed (cardiology, family practice, general internal medicine, orthopaedic surgery and psychiatry), and discusses the study's relevance and implications for medical education.  相似文献

Racial identity and academic attainment among African American adolescents   总被引：2，自引：0，他引：2  

Chavous TM  Bernat DH  Schmeelk-Cone K  Caldwell CH  Kohn-Wood L  Zimmerman MA 《Child development》2003,74(4):1076-1090

In this study, the relationships between racial identity and academic outcomes for African American adolescents were explored. In examining race beliefs, the study differentiated among (a) importance of race (centrality), (b) group affect (private regard), and (c) perceptions of societal beliefs (public regard) among 606 African American 17-year-old adolescents. Using cluster analysis, profiles of racial identity variables were created, and these profile groups were related to educational beliefs, performance, and later attainment (high school completion and college attendance). Results indicated cluster differences across study outcomes. Also, the relationships between academic attitudes and academic attainment differed across groups. Finally, the paper includes a discussion on the need to consider variation in how minority youth think about group membership in better understanding their academic development.  相似文献

Effects of visual grouping strategies of computer-animated presentations on selective attention in science     

Lloyd P. Rieber 《Educational technology research and development : ETR & D》1991,39(4):5-15

The effects of visual grouping strategies involving animated and static graphic presentations on selective attention were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an animated sequence. A total of 39 fourth-graders participated in an introductory lesson on Newton's laws of motion. Two levels of Visual Presentation (Static Graphic, Animated Graphic) were crossed with two levels of Visual Grouping (Grouped, Ungrouped). A within-subjects factor consisted of two levels of Learning Intent (Intentional, Incidental). Results showed that students given animated presentations of lesson content outperformed students receiving static presentations, but only when the animated lesson frames were presented in groups, or “chunks,” of textual and visual sequences. Results also showed that students were able to successfully extract information pertaining to an application of Newton's second law incidentally presented in animated sequences. These latter results replicate earlier findings.  相似文献   

IQ and neuropsychological predictors of academic achievement     

Susan Dickerson Mayes  Susan L. Calhoun  Edward O. Bixler  Dennis N. Zimmerman 《Learning and individual differences》2009,19(2):238-241

Word reading and math computation scores were predicted from Wechsler Abbreviated Scale of Intelligence Full Scale IQ, 10 neuropsychological tests, and parent attention deficit hyperactivity disorder (ADHD) ratings in 214 general population elementary school children. IQ was the best single predictor of achievement. In addition, Digit Span contributed significantly to reading prediction, and the Developmental Test of Visual-Motor Integration (VMI) and Coding contributed to math prediction. The remaining neuropsychological test scores did not significantly improve achievement prediction. Exploratory factor analysis yielded a general ability factor (comprising the four IQ subtests, Digit Span, VMI, reading, and math), five factors made up solely of subtests from single measures (Wisconsin Card Sorting Test, Stroop Color and Word Test, Gordon Diagnostic System, California Verbal Learning Test, and ADHD ratings), a factor consisting of Grooved Pegboard Test and Coding, and a factor consisting of Symbol Search and Animal Naming Test.  相似文献   

Men’s and Women’s Intentions to Persist in Undergraduate Engineering Degree Programs     

James P. Concannon  Lloyd H. Barrow 《Journal of Science Education and Technology》2010,19(2):133-145

This is a quantitative study of 493 undergraduate engineering majors’ intentions to persist in their engineering program. Using a multiple analysis of variance analysis, men and women had one common predictor for their intentions to persist, engineering career outcome expectations. However, the best sociocognitive predictor for men’s persistence was not the same for women. Men’s persistence in undergraduate engineering was predicted by their abilities to complete the required coursework. Women’s persistence in undergraduate engineering depended upon their beliefs in getting good grades (A or a B). In brief, women’s intentions to persist in undergraduate engineering were dependent upon higher academic standards compared to men.  相似文献   

Injury prevention in male youth soccer: Current practices and perceptions of practitioners working at elite English academies     

Paul J. Read  Pablo Jimenez  Jon L. Oliver  Rhodri S. Lloyd 《Journal of sports sciences》2018,36(12):1423-1431

Forty-one practitioners inclusive of physiotherapists, sports scientists and strength and conditioning coaches from the academies of elite soccer clubs in the United Kingdom completed an on-line questionnaire which examined their: (1) background information; (2) perceptions of injury occurrence and risk factors; (3) screening and return to play; and (4) approach to designing and delivering injury prevention programmes with a response rate of 55% (41/75). Contact injuries were the most common mechanism reported and players between 13–16 years of age were perceived to be at the greatest risk. Pertinent risk factors included: reduced lower limb and eccentric hamstring strength, proprioception, muscle imbalances, and under developed foundational movement skills. Joint range of motion, jump tests, the functional movement screen, overhead and single leg squats were the most utilised screening methods. Training modalities rated in order of importance included: resistance training, flexibility development, agility, plyometrics and balance training. Training frequency was most commonly once or twice per week, during warm-ups, independent sessions or a combination of both. Injury prevention strategies in this cohort appear to be logical; however, the classification of injury occurrence and application of screening tools to identify “at risk” players do not align with existing research. The frequency and type of training used may also be insufficient to elicit an appropriate stimulus to address pertinent risk factors based on current recommendations.  相似文献
