In recent years, many U.S. states have introduced growth models as part of their educational accountability systems. Although the validity of growth‐based accountability models has been evaluated for the general population, the impact of those models for English language learner (ELL) students, a growing segment of the student population, has not received sufficient attention. We evaluated three commonly used growth models: value tables or transition matrices, projection models, and student growth percentiles (SGP). The value table model identified more ELL students as on track to proficiency, but with lower accuracy for ELL students. The projection and SGP models were more accurate overall, but classified the fewest ELL students as on track and were less likely to identify ELL students who would later be proficient. We found that each model had significant trade‐offs in terms of the decisions made for ELL students. These findings should be replicated in additional state contexts and considered in the development of future growth‐based accountability policies. 相似文献

Stanley B. Baker Herbert A. Exum Richard E. Tyler 《Counselor Education & Supervision》2002,42(1):15-30
The authors investigated C. E. Watkins's (1994) supervisor complexity model (SCM). The Psychotherapy Supervisor Development Scale (PSDS; C. E. Watkins, L. J. Schneider, J. Haynes, & R. Nieberding, 1995) was used to ascertain development over a 15‐week supervision practicum for 12 doctoral students and to compare their development with 7 doctoral students who had not yet begun their practicums. A set of retrospective interview questions produced responses that were used to investigate the viability of the 4 proposed discrete developmental stages in the SCM. The PSDS findings are congruent with theory. The retrospective interview findings, although interesting, are less definitive. Recommendations for research and training are presented. 相似文献

Attitudes and approaches toward the collection, use, and care of color photographs have evolved enormously since the official arrival of commercially viable color photographic processes in the early twentieth century. This article traces the evolution of collection, exhibition, and preservation practices for works of art in color photography over the last few decades, as represented by one institution, The Metropolitan Museum of Art. 相似文献
