Recognizing the persistent science achievement gap between inner‐city African American students and students from mainstream, White society, this article suggests that the imposition of external standards on inner‐city schools will do little to ameliorate this gap because such an approach fails to address the significance of the social and cultural lives of the students. Instead, it is suggested that the use of critical ethnographic research would enable educators to learn from the students how science education can change to meet their aims and interests. The article includes a report on how a science lunch group in an inner‐city high school forged a community based on respect and caring and how this community afforded African American male teens the opportunity to participate in science in new ways. © 2001 John Wiley & Sons, Inc.

Conclusions Although we do not understand very well what the processes are that contribute to language development, it is clear that communication plays a central role. As children strive to become increasingly skilled at communicating their ideas (White, 1959), as they have increasingly complex ideas to communicate (Piaget, 1955), and as they encounter an increasingly diverse set of people with whom to communicate (Brown, 1973), they must learn to use language which is richer and more flexible.When children come to school or to a day care center they already know a great deal about language. They have readily and actively mastered words, sentences and forms of communication which they need in their own family and community. In their new environment—the school or center—children's language development can further be fostered by adults who are receptive to children's efforts at communication. Adults who encourage children to use language in new ways, who attend to what children mean to say and who recognize that children's errors are often not mistakes, are likely to play a positive role in children's language development.Janet H. Kane and Karen Sheingold are on the Staff at Bank Street College of Education.  相似文献

It is well established that technological education is not just about the development of technical expertise. A socially constructed view of technology aims to recognise the culture of technology. Technology education as expressed in the New Zealand curriculum provides an opportunity for societal issues to have equal space with technological capability and technological knowledge. However, when technological activities focus on solutions it is all too easy for stakeholders' positions to be ignored. There is a need for a teaching approach to engage in a liberating technological literacy discourse where values and beliefs of all participants directly and indirectly involved in the activity, are examined. This research monitored a professional development programme where identification of the values represented in a familiar object provided a model for discussion and the development of a teaching environment that promoted consideration of values during problem-solving. The data have been collected from primary school teachers who developed teaching programmes for Years 1 to 8 (5–12 years).  相似文献

Institutional administrators, faculty, state planners, and legislatures have little analytical basis available to help them cope with the expected excess higher education capacity of the 1980s. Without objective criteria, state planners and legislatures are likely to propose across-the-board reductions even if it were preferable to close some institutions and expand others. This study is a case application of an optimization model to two community colleges in northern Minnesota. Using estimated enrollment demand functions and readily available data on size, quality, and costs, this model is designed to assist policymakers in identifying overbuilt institutions and programs that should be closed. The state's objective in the model is to satisfy specified proportions of enrollment demand with a minimum expenditure of state funds.  相似文献

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning.  相似文献

The educational technologist's work in Open University course production is described in terms of its context and the potential roles and tasks that may be assumed. Although potential roles and tasks might be shared with other educational technologists, the Open University context of course production is singular to that institution and provides special problems. It is concluded that the educational technologist must continually construct and reconstruct his own role according to a number of sets of criteria.  相似文献

The need for those working in a variety of settings to interact effectively with technical experts has grown dramatically in recent years as computers have become essential to the performance of an increasing broad range of professional work. This article presents a case of this sort of interprofessional interaction, exploring the process and outcomes of collaboration between technical professionals and educators working to bring Internet access to an urban public school district. Drawing on field note and interview data, the case reported here illustrates how differences in institutional routines and professional values can generate differing agendas, contrasting assumptions, and contrasting expectations concerning project products and outcomes among collaborators from different professional worlds. In the case we describe, these differences affected such central matters as the types and usefulness of technical resources to which users had access as well as users' confidence in the technology. The case also illustrates how aspects of this interprofessional conflict were addressed through an organizational change. The kinds of issues that arose in this project are likely to occur in a variety of professional settings; therefore, examination of this case provides insight into a variety of issues and dynamics that should be considered when embarking upon or analyzing any interprofessional collaborative effort, and particularly one that involves technical professionals.  相似文献

In their race to provide the ultimate guide to the moon, two 17th-century astronomers proposed lunar maps and nomenclatures that they hoped would gain international currency. But the names we use today were those proposed by the Jesuit, a friend of Galileo's persecutors, in a book whose purpose was to refute the Copernican system once and for all. We now believe that Riccioli was wrong about the universe, but why do we still use his nomenclature? The keys to this foundational visual debate in astronomical image-making are the moon maps themselves.  相似文献

OBJECTIVES: The objectives of this work were to identify the sources of information currently received, information-seeking behaviours, information requirements and preferences for future information provision amongst health and social care professionals providing care to children with health care needs. METHODS: Data were collected using a cross-sectional postal questionnaire survey. RESULTS: A wide range of information resources was reported as being available to professionals. However, a large proportion of respondents found it necessary to perform additional searches for information, suggesting that current resources were not satisfying their needs. The majority of professionals reported a preference for electronic formats, whilst a smaller proportion preferred hard copy materials. Participants promoted the use of informal networks as a means of support and exchange of information. CONCLUSION: Supplementing the information that is provided in electronic and hard copy formats, by enhancing informal networks, may be the most effective way of meeting the information needs of this group of professionals.  相似文献
