Educational leadership can be defined as the ability of a principal to initiate school improvement, to create a learning-oriented educational climate, and to stimulate and supervise teachers in such a way that the latter may execute their tasks as effectively as possible. In 1989, 1993, and 1998, teacher perceptions of educational leadership of principals in Dutch elementary education were evaluated by means of a Rasch-scale. It turned out that the educational leadership of Dutch principals has grown considerably. In both 1989 and 1993 the effect of educational leadership on pupil achievement was investigated. While in 1989 no significant relationship was found, the results of 1993 show a significant relationship between educational leadership and average pupil achievement over 3 successive years corrected for school environment.  相似文献

Abstract

An empirical examination of accredited American higher education institutions was conducted to obtain baseline data regarding distance education copyright, intellectual property, and antitrust concerns. Additionally, a multiple‐case study involving ten of the top thirty accredited distance education institutions in America was conducted. Policy approaches were examined for all institutions, and differences were discussed between public and private institutions as well as between the following Carnegie Classification institutions: Research I and II, Doctorate I and II, and Master's I and II. Data indicated that, out of the schools surveyed, 22% of the institutions in these Carnegie Classification categories published copyright and intellectual property policies on their institution's Web site. In the case study, it was found that 90% of the institutions centrally controlled their distance education program administration as well as the copyright and intellectual property policies related to it.  相似文献

This paper addresses the parallel between the changes in students' and teachers' learning advocated by constructivist science educators. It begins with a summary of the epistemology of constructivism and uses a vignette drawn from a set of case studies to explore the impact of a constructivist science in‐service programme on an experienced and formal elementary science teacher. Judged by constructivist standards, the teacher described in the vignette makes very little progress. The irony of applying a constructivist critique to his work, however, is that it fails to treat the teachers' imperfect knowledge of teaching with the same respect as constructivists treat students' imperfect learning of science. The remainder of the paper explores this constructivist paradox, and suggests that‐like students' knowledge of science‐teachers' knowledge of constructivist science teaching is likely to grow through slow and gradual re‐formation of their established understanding of classroom theory and practice.  相似文献

This paper reports a small‐scale longitudinal enquiry into the development of children's ideas on light and vision. It followed the same class from Year 4 (age 9) through to Year 6 (age 11), but the greater part of the information came from Year 5. The data were derived from the children's drawings and written responses, and from small group interviews. Care was taken to ensure that the ideas elicited were the true beliefs of the children. No formal instruction in the subject had been given, nor was any attempted. In the analysis, the children's views have been classified according to a hierarchical set of models, which reflect the strong adherence to an active vision interpretation held by the majority. The extent of progression towards the more scientific view is reported. In the introduction and discussion comparison is made between contemporary non‐scientific conceptions of vision, and the speculations of pre‐scientific philosophers. A final section presents some implications of these findings for teaching the topic.  相似文献

The purpose of this study was to intervene in the process of the Halliwick Method (swimming), in order to improve the method, or some of its aspects, for a sample of 14 individuals with Downs syndrome (aged six to 21 years), using both an individualized educational setting approach and a differentiation of the elements of the Halliwick Method. The pre-intervention phase included medical examination, IQ, measurement of the behaviour according to the Rutter Scale and a Test of Physical Performance for each subject. Next, the subjects were assigned to seven pairs of case studies, where each individual following a Halliwick Methods swimming programme was paired with an individual following a modified swimming programme based on the same method, on physical health variables, IQ, behaviour and motor abilities. The duration of each swimming programme was 24 weeks for each individual, at a frequency of once per week, for 40 minutes. In the light of the findings of this study, further recommendations for the improvement of Halliwick Method procedures were made, common factors that affected the performance of each individual were identified and their relation with performance was explored.  相似文献

Abstract

Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable.  相似文献
