Many western countries are paying increasing attention to the organization and administration of graduate studies. Such attention has developed from primary concerns about completion times, completion percentages, programme quality, and student quality, as well as secondary concerns about supervisors, funding, coursework, inter-organizational co-operation, and policies and practices of both universities and research councils. Using information about British graduate programmes as a basis, the article presents policy issues related to research councils, funding councils, and control, followed by discussion of the themes of the nature of programmes, supervision and evaluation, completion time, quality, and innovation. The final sections address several concerns and offer some suggestions.  相似文献

Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience.  相似文献

The 1991 Janet Doe lecturer describes the vision held by the founders of the Medical Library Association of medical information being readily accessible to health professionals no matter how far they were located from major medical centers, and traces the pursuit of this vision to current outreach activities.  相似文献

Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively.  相似文献
