Abstract

The aim of this study is to examine possible applications of new information technologies (NIT) in special education within different educational, socio‐economic and socio‐cultural contexts and, in particular, the possibilities of transference of these applications from the industrialised nations to the developing countries. The study also contains references to positive and negative results of the use of NIT in the special education of children, youth and adults.  相似文献

Abstract

Students develop robust mental models of teaching and learning during their school years, and as such, often teach as they were taught—possibly perpetuating practices that limit intellectual inquiry in classrooms. This paper reports on an analysis, using a conceptual framework and NUD?1ST software, of a cohort of 3rd‐year teacher education students' reflections on changes in their mental models following their experiences in a problem‐based learning (PBL) topic. Results provide evidence that students do report changing mental models in areas such as (a) the value of case studies for engaging with subject content, motivating learning, and connecting theory with practice; (b) self‐reflection and peer collaboration for cognitive and professional growth; and (c) processes of inquiry for developing self‐regulated learning practices.  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
