A major investment in educational television programmes by the federal government led the United States Department of Education to seek ways to extend the audience size for these programmes beyond public television by placing them on commercial broadcast stations in America. This article describes the programmes, the marketing organization and strategies used to promote programming to the commercial marketplace, and the successes achieved in persuading commercial broadcasters to accept educational children's programming, particularly programmes aimed at minority audiences.  相似文献

The aim of this study is to elicit from staff members and from postgraduate students their personal constructs of research effectiveness. Based on Kelly's Personal Construct Theory, the repertory grid technique was used to elicit, analyse, discuss, and negotiate individual and group constructs of research with the result of arriving at a greater group consensus and a clearer picture of shared criteria for research effectiveness.  相似文献

网上的学与教是全球关注的一个教育热点,这种关注大致体现在:(1)课程本身的问题,即我们将要教什么?(2)学习自身的性质。(2)学习以及他们所需要的学习环境,(4)对教育提供的影响。(5)不同的国家为规范远程学习和网上学习所采取的的不同方式。(6)我们一旦选择这种方式所存在的大量的合作机会,其中也存在同样多的健康或不健康的竞争,(7)与那些在网络时代所提供机遇面前落伍的人们有关的。  相似文献

Kindergarten, third-grade, and sixth-grade children were told 2 stories about a group of children who made artwork that was subsequently sold at a craft fair. The characters in one story were described as friends, while the characters in the other story were described as strangers (relationship condition). 1 character in each story was presented as the oldest in the group, 1 as the most productive, and 1 as the poorest. Children were asked to allocate 9 dollars to the 3 characters under each relationship condition, provide rationales for those allocations, and rate the fairness of 4 different patterns of allocation. Older children allocated more money to needy friends than to needy strangers and more to productive strangers than to productive friends. Kindergartners' allocations and fairness ratings did not vary with relationship. Rationales for allocation judgements suggested that equality was the most salient principle for decisions at all ages, but the older children provided rationales based on benevolence more often than younger children when characters were presented as friends.  相似文献

The present study aims at assessing faculty attitudes toward institutional competitive strategies in U.S. research universities and at exploring some of the correlates of these attitudes.

A stratified random sample of 40 U.S. research university departments, 10 each in physics, sociology, electrical engineering, and education was surveyed by means of a questionnaire.

The major findings of this study suggest that faculty members at research universities express non‐receptive attitudes toward university generic strategies, although, more productive,more satisfied and more committed faculty members are relatively more receptive toward university strategies than less productive, less satisfied and less committed faculty members.

The meaning and the implications of these findings are discussed.  相似文献

Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so‐called information‐rich and information‐poor. Such concerns have led to high‐profile information technology policy initiatives in many countries. In Australia, in an attempt to ‘redress the balance between the information rich and poor’ by providing ‘equal access to the World Wide Web’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make ‘technology affordable for all Australians’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]). In this paper, we examine four families, one of which had long‐term Information and Communication Technologies (ICT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with ICT and suggest that previously disadvantaged family members are not particularly advantaged by their access to ICT.  相似文献
