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

ABSTRACT

This paper considers the examination results of TVEI and non TVEI pupils in the database established at the University of Newcastle in 1985‐87. The pupils took national exams in the summer of 1987, when they were about 16 years old. Their average grades (Exam Means) and their accumulated grades (Exam Totals) were considered separately.

The Exam Mean and Exam Total scores were generally worse for TVEI than non TVEI pupils, even when pupils with the same ability test scores and aspirational scores were compared. However, it is possible that non TVEI factors caused the discrepancy in results and it is these factors which are the subjects of this paper.

The paper considers firstly whether the differences are an artefact of regression analysis. Secondly, the data are considered using various multilevel models. Both analyses suggest that there was no TVEI effect on the Exam Mean score and a negative TVEI effect on the Exam Total. Various explanations for these findings, concerning internal school allocational and curriculum policies, are considered and discussed.  相似文献

Creating opportunities for inclusive participation by older people in local governance is made more complex by their diversity, which can shape who participates, in what ways, and how effectively. The existing research, however, largely focuses on the impact of socio-demographic characteristics or of individual barriers on participation, without considering how interactions between these may shape pathways to participation among older people. This quantitative study explored the relationships between participation by older people, barriers to participation, and socio-demographic characteristics. The results indicate that socio-demographic diversity impacts on the importance attributed to barriers as well as the strength and direction of their relationships with participation. The findings problematize the dominant approaches to understanding barriers to and patterns in participation. A more sophisticated understanding of inclusive governance in ageing communities needs to consider the iterative and interactional nature of pathways to participation in the context of the complexity of the “older population.”  相似文献
