Abstract

In this article, we describe an investigation in which a teacher taught four students with moderate mental retardation to read sight words using a progressive time‐delay procedure. Definitions of the target words were presented incidentally in the consequent statement. Through the small‐group arrangement, students had the opportunity to learn through observation the other students' target words and incidental information. All students acquired their target words and at least 50% of the incidental and observational words and definitions to which they were exposed. We interpret these data as suggesting that teachers should systematically include related nontargeted information in their instruction and provide opportunities for observational learning to occur.  相似文献

This paper is concerned to demonstrate the usefulness of the theory of Bourdieu, including the concepts of field, logics of practice and habitus, to understanding relationships between media and policy, what Fairclough has called the ‘mediatization’ of policy. Specifically, the paper draws upon Bourdieu’s accessible account of the journalistic field as outlined in On television and journalism. The usefulness of this work is illustrated through a case study of a recent Australian science policy, The chance to change. As this policy went through various iterations and media representations, its naming and structure became more aphoristic. This is the mediatization of contemporary policy, which often results in policy as sound bite. The case study also shows the cross‐field effects of this policy in education, illustrating how today educational policy can be spawned from developments in other public policy fields.  相似文献

The purpose of the study reported here was to analyse the ways in which unversity entrant science students carry out and communicate experimental activities and to identify a model to explain characteristic communication practices. The study was prompted by a need to inform the development of an introductory laboratory course. The students studied shared an educational background characterised by a lack of experience with laboratory work and scientific writing. Seven groups of three students were studied. The investigative strategies of these groups were observed. Laboratory reports were used to identify the ways in which students communicated these strategies. Data are presented that show a discrepancy between the strategies used and those reported. The results suggest that: (i) students' perceptions of the purpose of a laboratory task influence their decisions on what to report; (ii) understandings of laboratory procedures greatly influence their decision on what to report and on how much detail to include in a report and; (iii) knowledge of discourse rules contributes to effective reporting. It is concluded that students' communication of an investigation results from the differential operation of various perceptual filters that determine both the procedural and discourse elements of their reports. It is recommended that the communication of science should be taught explicitly and alongside the procedures and concepts of science. © 2000 John Wiley & Sons, Inc.
