ABSTRACT

American high schools present an extremely difficult, nearly intractable setting for serious educational reform efforts. Yet such efforts can succeed. This article reports results from a survey of 179 urban comprehensive high schools that were successfully implementing change programs based on effective schools principles.

All schools encountered problems of implementation. Larger‐scale, instructionally‐oriented, and longer‐lasting programs induced more problems. Problems were only moderated, not eliminated, by good‐quality planning.

Given the problem‐richness of change efforts, the major determinant of successful implementation was good problem‐coping. It was made more likely by the presence of consensus (shared vision), support of key stakeholders in and out of the school, planning quality, external assistance, and administrative time spent. Case studies showed that the presence of an empowered change management group aided all these critical factors.

Schools with the most impact (defined as student outcomes, teacher improvement, and organizational improvement) had focused on teacher or organizational changes to begin with, coped with the inevitable problems well, had internal and external constituencies supporting the change effort, and sustained the work for a longer period of time (typically 4‐5 years).

The key variables appear to form a coherent causal network. Implications for change management are drawn.  相似文献

This study investigates the preservice teacher learning in the context of conversations about their field-based challenges. First, a review of the literature explores studies that highlight the role of evidence-based conversation as a mechanism to approach the inevitable problems faced by teachers in the classroom. The subsequent case study provides an analysis of how a group of preservice teachers approached a colleague's challenge through a structured conversation and used digital videotapes and artifacts to add specificity to their analysis. The study's implications suggest how constructive and critical conversations between prospective teachers can play an important role in their professional development.  相似文献

The main purpose of this study was to investigate the effects of active learning on preservice teachers' dignity, energy, self-management, community, and awareness (DESCA) abilities, attitudes toward teaching, and attitudes toward science. Third year preservice teachers (n = 77) from two different classes were involved in the study. One intact class was assigned as the experimental group, whereas the other intact class was assigned as the comparison group. The comparison group students received the instruction by traditional teaching, and the experimental group received instruction through an active learning paradigm. DESCA abilities and attitudes were measured before and after instruction. Results revealed that there was a significant difference favoring the active learning instruction on preservice teachers' DESCA scores; however, there was no significant difference on preservice teachers' attitudes toward teaching and science.  相似文献

Notwithstanding an ongoing concern about the low representation of certain groups in higher education, there is reluctance on the part of politicians and policy makers to adopt positive discrimination as an appropriate means of widening participation. This article offers an account of the different objections to positive discrimination and, thereafter, clarifies and criticises the view that universities ought to select those applicants who are expected to be most successful as students. It distinguishes arguments from meritocracy, desert, respect, and productivity and shows how these arguments are compatible with the use of positive discrimination in higher education.  相似文献

The librarians of the Health Sciences Library worked with the director of the Primary Care Clerkship to reinforce the principles of Evidence-Based Medicine (EBM) searching, taught during the first two years of medical school, through an intensive workshop. The purpose of the program was to ensure that students apply EBM principles in a timely and effective manner in clinical situations. Working in teams led by a resident and librarian, students researched real cases and then evaluated the effectiveness of their approach to the problems. This paper outlines the rationale for the team approach, reviews the administration of a computer-based workshop, and discusses the evaluation process. Evaluation focused on both the current workshop and its implications for the informatics program presented to students during years one and two.  相似文献

The aim of our study was to determine if any immediate changes in balance were discernable in college soccer players after a specially designed heading session. Eight male and two female skilled collegiate soccer players had a baseline balance pre-test using the Balance Master, followed by heading 20 balls kicked consecutively by a teammate from the touchline to a point near the goal, which was followed by a post-test using the same testing technique. Paired t-tests were used to compare balance ability between pre- and post-test conditions. There was no difference in balance pre- to post-test (85.3% and 86.2% respectively). No significant difference was noted from pre- to post-test in the mean equilibrium scores for conditions three through six on the Sensory Organization Test, with the exception of condition four, which revealed a significant increase from pre- to post-test. We concluded that an acute session of heading soccer balls may not result in balance changes in collegiate soccer players.  相似文献
