This paper reports the relationship between four English primary teachers’ understanding of the nature of science and their practice. Action research was included as a major part of the research design in order to explore the dialectical interplay between various factors at work in the teachers’ practice. The influences of both tacit and espoused understandings of the nature of science were considered alongside the teachers’ beliefs about education, teaching, and learning. These beliefs were found to be the determining factor in the teachers’ decisions about classroom strategies. In arguing for a dialectical perspective on teachers’ practice, the research suggests that teachers’ espoused understanding of the nature of science may also be at least partially formed by the influence of these beliefs, raising the possibility that influence may run from teaching to theoretical understanding and not the other way round. 相似文献

Action research has become a widely accepted and recommended methodology for teacher research. With the current climate of collaborative planning within primary schools. it has been seen as a process which could exist naturally alongside such activity, with much being made in the rhetoric of its essentially ‘collaborative’ character. But such claims are problematic. They derive importantly from epistemological considerations, but weaknesses may be found in such arguments when they are considered against the reality of the process in action. This article considers the claims for the collaborative nature of action research in the context of the progress of a coordinated inquiry in a primary school, within which the author was involved. Whilst recognising their importance, it challenges the arguments for insisting on collaboration as a prerequisite for the most ‘effective’ action research, suggesting that all action research is fundamentally personal. It also raises the question of whether participation in the process may itself raise conflicts with the need for a collaborative structure to ensure critical reflection and valid knowledge claims, suggesting that action research may at times have effects at a personal level which could produce severe tensions in the maintenance of a collaborative situation. 相似文献

Children come to school with an idea of narrative structure, but their knowledge of persuasive writing is less developed. Results of the National Assessment of Educational Progress indicate that students perform poorly on persuasive writing tasks. To what extent this is a result of a lack of logical thinking skills and to what extent it is a result of problems with instruction are not known. The present experiment was designed to identify the effects of instruction, grade level, and sex on students’ persuasive writing. Children in grades 4, 6, and 8 were instructed in writing with one of four instructional strategies. Their performance was then evaluated through analytic scoring of their efforts with standard writing prompts administered immediately after treatment and again 2 weeks later. The results showed that older children wrote better than younger ones; that girls wrote better than boys immediately after the study but not 2 weeks later; and that treatment effects approached statistical significance. 相似文献

This paper describes a qualitative approach to analysing students' concept maps. The classification highlights three major patterns which are referred to as 'spoke', 'chain' and 'net' structures. Examples are given from Year 8 science classes. The patterns are interpreted as being indicators of progressive levels of understanding. It is proposed that identification of these differences may help the classroom teacher to focus teaching for more effective learning and may be used as a basis for structuring groups in collaborative settings. This approach to analysing concept maps is of value because it suggests teaching approaches that help students integrate new knowledge and build upon their existing naive concepts. We also refer to the teacher's scheme of work and to the National Curriculum for science in order to consider their influence in the construction of understanding. These ideas have been deliberately offered for early publication to encourage debate and generate feedback. Further work is in progress to better understand how students with different conceptual structures can be most appropriately helped to achieve learning development. 相似文献

To academic visionaries the new century appears to have an emerging environment characterized by increased complexity, uncertainty,
unpredictability which, some have argued, render traditional notions of planning and management irrelevant. The expectations
of management and planning scholars carry the implicit assumption that somehow individual capability and organizational capacities
will rise to meet the enormous challenges of this new environment. In the light of this situation the purposes of this paper
are: (1) to briefly examine the limitations and criticisms of traditional educational planning; (2) to outline the emerging
concepts and processes which collectively form a new paradigm for strategic planning; (3) to discuss the new model within
the context of changing national policy and planning environments and increased localization; (4) to review the limited results
of empirical research related to more participatory planning models; and (5) to offer a critique of the assumptions and practicality
of the new model in the process of planning and sustaining educational change in developing countries 相似文献

(I) Evidence has been given that the so-called permanent electrets of Eguchi are not permanent, but that their polarization decays with the time. At room temperatures this decay is too slow to be observed directly; but it is the decay of the polarization that, at least in part, accounts for the presence of the free charges that are always observed. At higher temperatures the results that have been obtained are consistent with the view that the rate of decay of the polarization increases very rapidly with the temperature; so much so that the polarization may be almost completely destroyed at a temperature which is not high enough to cause any appreciable softening of the waxes that form the substance of the electrets.(2) As is to be expected from Lord Kelvin's hypothesis as to the cause of pyro-electricity, these electrets have been shown to possess the pyro-electric property.(3) The piezo-electric effect, which always accompanies the pyro-electric property, has been shown to be exhibited by these electrets. 相似文献
