The Education and Training of Teachers and Professionals in the Face of the Microcomputer Revolution
I Meidan 《Educational Media International》2013,50(1)
Mr Meidan started his presentation by highlighting the difficulty of defining the needs of a training system for the microcomputer age. He identified three dimensions to this problem: first, that it is a comparatively new innovation and one which is still evolving; second, that we are behind in understanding its precise influence in the educational field; and third, the psychological aspect, the possible resistance to change. All these presented a challenge and suggested the need to identify carefully population segments most likely to be affected by change in order to define possible training programme requirements. He saw three main groups requiring training: the professionals, the users and the instructors. 相似文献

A variety of important life consequences for literacy are widely assumed in the contemporary discourse on adult literacy with little, if any empirical research to support them. As a result, they have been variously labelled as ‘myths’ (Coombs 1985), ‘doubtful promises’ (Hinzen 1983), proclamations of ‘faith’ (Winchester 1990) and ‘claims in search of reality’ (Wagner 1992). Part of the problem here is that the effects of literacy are often identified without first defining what literacy is. Naturally, if literacy is ambiguously or broadly defined, virtually any consequence can be attributed to it. Thus, the first task of any researcher, educator or policymaker involved with issues of adult literacy is to make his or her definitions of literacy and the scope of each definition's applicationsexplicit. Within the field of adult literacy education, Lytle and Wolfe (1989) provide a useful conceptual categorization for literacy in terms of four metaphors: literacy as skills, tasks, practices and critical reflection. This paper extends Lytle and Wolfe's framework to identify what consequences are attributed to literacy within each of the four metaphors, focusing on adults in the developing world. 相似文献

A silver nitrate test is described for the quantitative determination of residual hypo in photographic prints. The hypo is converted in situ to silver sulfide, the transmission density of the sulfide determined, and the hypo content obtained by reference to a standard curve.The method used to establish the standard curve is outlined, the data being verified by quantitative analyses.A simplified procedure is suggested involving the application of a drop of silver nitrate to the back of the print and then matching the spot visually with a set of standards. 相似文献
