This article considers a secondary science department that has, since 2000, developed distributed leadership as a form of human capacity building. Using a longitudinal ethnographic case study allowed us to consider how distributed leadership can be nurtured and developed in a department. Our analysis centres on two key issues: the nature and pattern of distributed leadership practices and the continuity that provides coherence to those practices. From our analysis, there appear to be two major conclusions. The first of these is the need for administrators to be purposeful in the appointments that they make to formal leadership positions. To enact distributed leadership practices requires leaders who can exercise both formal power and influence. The second conclusion relates to the time required for continuity of leadership practices to give rise to changes that lead to teachers managing the teaching and learning programme. 相似文献

The authors present the feasibility and acceptability of a parent sexuality education program led by peer educators in community settings. They also report the results of an outcome evaluation with 71 parents who were randomized to the intervention or a control group and surveyed one month prior to and six months after the four-week intervention. The program was highly feasible and acceptable to participants, and the curriculum was implemented with a high level of fidelity and facilitator quality. Pilot data show promising outcomes for increasing parental knowledge, communication, and monitoring of their adolescent children. 相似文献

The Vanderbilt Assessment of Leadership in Education (VAL-ED) provides educators with a tool for principal evaluation based on principal, teacher, and supervisor reports of principals’ learning-centered leadership. In this study, we conduct a known group analysis as part of a larger argument for the validity of the VAL-ED in US elementary and secondary schools. We asked superintendents to select the principals in their district who they believe in performance of their duties are in the top 20 % and the bottom 20 %. We ask how accurately VAL-ED scores can identify membership of the two known groups. Using a discriminant analysis, the VAL-ED places principals in the superintendent groups, on average, 70 % of the time for both elementary and secondary schools. Placement accuracy is greater for the top group than the bottom group. 相似文献

This paper investigates the number of expansion terms to use in automatic query expansion by examining the behavior of eight
retrieval systems participating in the NRRC Reliable Information Access Workshop. The results demonstrate that current systems
are able to obtain nearly all of the benefit of using a fixed number of expansion terms per topic, but significant additional
improvement is possible if systems were able to accurately select the best number of expansion terms on a per topic basis.
When optimizing average effectiveness as measured by mean average precision, using a fixed number of terms increases the score
a large amount for a small number of topics but has little effect for most topics. The analysis further suggests that when
a topic is helped by automatic feedback, the increase is from a set of terms that reinforce each other rather than from the
system finding a single excellent term. 相似文献
