1 Introduction New technologies and other developments haye changedthe information seeking behaviors of the academic communityand the general public.Nowhere is this more evident than inthe exponential growth of the World Wide Web and cellularphone usage.Responding to these user needs and newtechnologies,libraries are moving from being InformationWarehouses to becoming Information Portals.Full-text  相似文献

In order to assess the current status of MEDLINE training provided by schools of library science, a survey was conducted of those schools having an educational identification code issued by the National Library of Medicine. Information was gathered on such variables as the instructors' background and preparation, the course objectives and content, and the amount of on-line experience provided to students in each of eleven programs. An evaluation of these measures indicates that more opportunities to gain experience in using MEDLINE should be initiated by library schools and that current efforts should be continued and expanded. Specific recommendations for accomplishing these goals are outlined; they are addressed to health sciences librarians, library school educators, the Medical Library Association, and the National Library of Medicine.  相似文献

In this article we review the notion of teacher knowledge from four metaphorical standpoints – teacher knowledge as computer, as craft, as complexity and as change. We employ each of these metaphors to examine and analyse the work of one teacher of science. We draw implications from our analysis for teacher education, teacher development and the study of teaching.  相似文献

The University of Hawaii at Hilo began offering a B.S. degree in computer science via distance education in 1998. This program serves students on islands with no four-year educational institution.The experiences in planning for and teaching such a program are discussed, together with the technologies used and the outcomes to date.  相似文献

Polyvocal approaches allow researchers and informants to interact on a more equal footing and informants’ voices to be heard in the final text. But research methods intended to empower informants also can be a source of unanticipated authorial power ‐ the power to confront informants with unsolicited self‐reflections and to textualize people's lives and words. The authors reflect on those ethical dilemmas in this article.  相似文献

There is little research investigating the maintenance of perceptual-cognitive expertise in general and even less comparing coaches of different ages. The aim of this study was to test for perceptual-cognitive differences between age groups, licence levels, and their interaction. This study investigated differences in skilled performance between young and middle-aged coaches of three different skill levels. Participants performed an accuracy-oriented pattern recall (mean distance in pixel) and a time-oriented flicker test (mean detection time in ms). There were some significant differences between age groups and between skill groups for both tests, but no interactions. For the pattern recall test, the effect sizes were larger for skill level differences, while for the flicker test effects were larger for ageing. These results suggest coaches are able to maintain accuracy skills better than reaction timed tasks. This is in line with findings on speeded performance in general populations, which show declines with age. Moreover, results also support findings on perceptual expertise in skills where accuracy was important.  相似文献
