Taking the deliberations of the recent Unesco conference on moral education (Sofia, April 1978) as his basis, the author argues that a radically revised pedagogy of moral education is needed if the potential of present-day youth for solving the increasingly complex problems of the world is to be fully exploited.  相似文献

This study focused on how the design of a national student survey instrument was informed and improved through the combined use of student focus groups, cognitive interviews, and expert survey design advice. We were specifically interested in determining (a) how students interpret the items and response options, (b) the frequency of behaviors or activities associated with the response options, (c) if the items are clearly worded and specific enough to produce reliable and valid results, and (d) if the items and response categories accurately represent students' behaviors and perceptions. We collected focus group data from 8 colleges and universities as part of a nationally funded research project on student engagement. The findings provide additional insight into the importance of using focus groups and cognitive interviews to learn how students interpret various items and what different responses really mean.  相似文献

There is probably no more dramatic an example of a developing country acquiring an industrial capability demanding the highest levels of technological and managerial skills, than that of the Indian nuclear industry. With the detonation of a nuclear device by India, much concern has been expressed that this is a case of nuclear proliferation resulting from an aid programme of a western state (Canada).This study demonstrates that rather than an aid programme, Canadian/Indian nuclear cooperation has been mutually beneficial to both countries' industries. In fact, India was a full risk-sharing partner in the development of the CANDU technology. It is also shown that there were no agreements with Canada broken by the Indian Government and that the detonation of the device was not a consequence of the links between the two programmes. Differences between the structures of the Canadian and Indian nuclear industries and the implications of these differences to broader national policies are discussed.The paper offers a basic criteria for the determination of the ‘appropriateness’ of a technology which, if applied to commercial nuclear power generating reactors, would result in a very gradual proliferation of this technology. In discussing the process of technology transfer, the paper identifies an optimal relative level of development between the industries of the two nations concerned. This relationship suggests that the most likely pattern of transfer in the future will be between LDCs that wish a new technological capability and other LDCs that have already acquired a certain level of competence.  相似文献
