Constructivism claims to be a postepistemology that replaces 'traditional' concepts of knowledge. Supporters of constructivism have argued that progress requires that pre-service teachers be weaned off traditional approaches and that they should adopt constructivist views of knowledge. Constructivism appears to be gaining ground rapidly and should no longer be viewed as an exercise in radical thinking primarily aimed at generating innovative teaching. It has become an integral part of the pedagogic mainstream. Close examination of the theoretical foundations of constructivism, however, reveals that the basic assumptions of constructivism are flawed. Far from being a postepistemology, constructivism simply regresses to a pre-Renaissance mindset with theology replaced with a psychologism. Constructivists should be aware that the implications of constructivism for future generations may be both profound and non-benign. 相似文献

This paper presents a content analysis of the manner in whichworld opinion is used in stories and editorialsof two nations' major newspapers. The authors studied the InternationalHerald Tribune and the Frankfurter Allgemeine Zeitung for themonths of February, March, and April 1986 for articles whichcontained implicit or explicit references to world opinion.These refernces were studied using a pre-designed survey instrument,which analyzed several features of the term's usage. Topicsfor discussion included: (1) the various syonyms for world opinion;(2) the agenda for world opinion; (3) the timing of referenceto particular issues on the agenda; (4) the moral and pragmaticcomponents of world opinion; and (5) the link between worldopinion and the international isolation of nationsor individuals. The paper concludes by combining the resultsof the study into a preliminary definition of world opinion,based upon the common usage of this term. The definition comparesthe characteristics of world opinion and publicopinion, and discusses the possible ramifications ofunderstanding the concept in this manner. 相似文献

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic medical literature retrieval system free of charge for an eleven-month period. Subjects conducted nearly nine thousand literature searches over a period of 942 system hours. Questionnaire data showed that participants could learn to use and would use an electronic information system, felt capable of using the system, utilized the system for a variety of purposes and in a number of different ways, and viewed the system as a valuable tool in searching the medical literature. The results are discussed in the context of the educational needs of the four user-groups and medical education planning by institutions. 相似文献
