Full WISC-R evaluations of students who are referred to a gifted program, but who do not meet placement criteria, have become a drain on the resources of many school districts. A screening formula for gifted students, utilizing three WISC-R subtests (VO-BD-SI), was evaluated using traditional epidemiologic techniques. The screen was applied to the records of 200 students who had been referred for a gifted program and received complete WISC-R batteries. Screen results were compared to actual placement of the 200 subjects based on a WISC-R Full Scale, Verbal, or Performance IQ of 130 or more. Measures of sensitivity, specificity, and predictive value of the screen were determined. The screen correctly detected the majority of gifted students and could have major implications in terms of cost effectiveness and professional time management. 相似文献

The primary study objective was to identify determinants of short-term recovery from a 161-km ultramarathon. Participants completed 400 m runs at maximum speed before the race and on days 3 and 5 post-race, provided a post-race blood sample for plasma creatine kinase (CK) concentration, and provided lower body muscle pain and soreness ratings (soreness, 10-point scale) and overall muscular fatigue scores (fatigue, 100-point scale) pre-race and for 7 days post-race. Among 72 race finishers, soreness and fatigue had statistically returned to pre-race levels by 5 days post-race; and 400 m times at days 3 and 5 remained 26% (P = 0.001) and 12% (P = 0.01) slower compared with pre-race, respectively. CK best modelled soreness, fatigue and per cent change in post-race 400 m time. Runners with the highest CKs had 1.5 points higher (P < 0.001) soreness and 11.2 points higher (P = 0.006) fatigue than runners with the lowest CKs. For the model of 400 m time, a significant interaction of time with CK (P < 0.001) indicates that higher CKs were linked with a slower rate of return to pre-race 400 m time. Since post-race CK was the main modifiable determinant of recovery following the ultramarathon, appropriate training appears to be the optimal approach to enhance ultramarathon recovery. 相似文献

The first two editions of the Handbook of Human Performance Technology helped define the rapidly growing and vibrant field of human performance technology—a systematic approach to improving individual and organizational performance. Exhaustively researched and edited by Dr. James A. Pershing, CPT, this third edition not only updates key foundational chapters on organizational change, evaluation, instructional design, and motivation, but features breakthrough chapters on “performance technology in action” and addresses many new topics in the field, such as certification, Six Sigma, and communities of practice. In this chapter, reprinted with permission of John Wiley & Sons, Inc. (copyright 2006), Roger Addison and Carol Haig take you on a journey through the key elements of a full performance process with its pitfalls and how to avoid them. 相似文献

This study reports the findings of a 2-year longitudinal study that examines the stance taken by a group of Western Australian teachers to the introduction of compulsory performance management in 1997. It shows that during the first year of implementation (1997), teachers responded to the new programme with significant levels of scepticism, mistrust and anxiety. By the second year (1998), despite continued reservations, the teachers found they could take charge of the process, maintain a sense of autonomy and control over their work, and capitalise on the limited opportunities for professional growth provided by annual appraisal cycles. A concluding theme emerging from the teachers' reported experiences and reflections is that management-inspired programmes of performance review have little impact on authentic teacher learning compared with active teacher participation in strong, accountable professional learning communities developed within and across schools. 相似文献

Organizations today face competitive conditions unlike those experienced in the past. Managers and team leaders must learn ways to get the highest level of performance from a team of people, work with a variety of individuals diverse projects, communicate with a wide audience clearly and effectively, and be able to provide performance feedback and elevate performance levels for people they hardly know. While few will argue that learning in organizations is critical to meeting these challenges, an increasing number of decision-makers are raising questions about the value of classroom training. The questions are especially difficult to address in sales training where results are observable (i.e., sales) but difficult to trace to performance events and interventions. The current study was conducted to address two questions: 1) Is it possible to link sales production to participation in classroom sales training? 2) If so, what are the elements of the training that seem to be most useful in enhancing employee performance and sales performance? 相似文献
