Sharon A. Shrock 《Performance Improvement Quarterly》1990,3(4):12-33
There is now widespread agreement that America's schools are in serious trouble. However, there is little consensus regarding what should be done about it. The school reforms currently being suggested are the most radical since the elimination of the one room school. School reforms of the 1980s—personnel selection, job redesign, evaluation/ feedback, incentives, instructional technology, and organization rede-sign—are reviewed from a performance technology perspectivee Reasons for their lack of success are discussed, in particular the schools' lack of interest in instructional design and technology. The most likely future reforms, those that involve the organizational redesign of schools, are discussed along with the impact such changes would have on the potential for applying performance technology in the schools. The paper concludes with actions that performance technologists in both business and academic environments can take to encourage the application of their technologies in the schools. 相似文献

In criterion‐referenced tests (CRTs), the traditional measures of reliability used in norm‐referenced tests (NRTs) have often proved problematic because of NRT assumptions of one underlying ability or competency and of variance in the distribution of scores. CRTs, by contrast, are likely to be created when mastery of the skill or knowledge by all or most all test takers is expected and thus little variation in the scores is expected. A comprehensive CRT often measures a number of discrete tasks that may not represent a single unifying ability or competence. Hence, CRTs theoretically violate the two most essential assumptions of classic NRT re liability theory and they have traditionally required the logistical problems of multiple test administrations to the same test takers to estimate reliability. A review of the literature categorizes approaches to reliability for CRTs into two classes: estimates sensitive to all measures of error and estimates of consistency in test outcome. For single test administration of CRTs Livingston's k2is recommended for estimating all measures of error, Sc is proposed for estimates of consistency in test outcome. Both approaches compared using data from a CRT exam and recommendations for interpretation and use are proposed. 相似文献
