In 2004, a professional delegation of multicultural educators visited the People's Republic of China to explore how diversity issues are addressed and how students are prepared for entry into the international workforce. The delegation, sponsored by the People to People Ambassador Programs, observed numerous parallels to the American system of education, including the challenge of providing equity for students of minority cultures, especially those in poor rural areas, and the conflict between modernization and preservation of cultural heritage.  相似文献

Results are reported in this paper from a study aimed at evaluating significant competencies in final-year students of some engineering programmes in Chile. The study was carried out by a group of eight universities that were interested in exploring ways to assess learning outcomes such as those demanded by the recent Chilean accreditation system. The authors actively participated in all stages of the study, contributing directly to the design, application and results evaluation of some tests. A sample of 150 students was tested, under conditions that guaranteed the comparability of results. In this paper the authors present results relating to the evaluation of effective communication. The study was backed up by a conceptual model and some hypotheses that are explained and discussed in this work.  相似文献

The formation of Stanford University's technology transfer program in the life sciences is analyzed from 1968 to 1982. The program evolved from multiple models based on divergent definitions of invention, inventor, rewards, and university-industry boundaries. The eventual program that emerged proved to be widely emulated. The norms of the academy shaped the uses of resources and the conditions of their appropriation. In turn, the currency of industrial science prompted the rethinking of academic norms. The analysis offers insight into the early stages of institutionalization, as the ambiguity of important categories and flexibility of policies were transformed into organizational routines. Today's ‘settled’ outcomes are the product of highly divergent practices.  相似文献
