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

Naoko Saito has made a good case for emphasising the 'tragic' dimension within Dewey's pragmatism. My response suggests ways in which Saito has not gone far enough. She does not adequately move beyond 'procedural pragmatism' to a 'programmatic pragmatism' which offers substantive articulations about the human good. In addition, her emphasis on 'Emersonian perfectionism' is misguided. Both the language of 'perfectionism' and the figure of Emerson are unsuitable for the project she intends. Speaking more concretely of a 'tragic–comic meliorism' allied to the novelist Hawthorne, it is suggested, provides a more fruitful path.  相似文献

Collaboration in research activity is now the rule not the exception. It is encouraged by government, funding bodies and research councils. However, the concept of collaboration is difficult to define. It occurs at many different levels, driven by a complex research system-policy dynamic. Three different models of collaboration – inter-personal, team and corporate – are identified, each with their own rationale, structure, benefits and costs. The paper examines the institutional implications of these models. It argues that institutions and individual researchers conceptualise and operationalise research collaboration in different ways. Although vital to institutional mission, collaborative research is rarely mapped by senior managers with any precision. In general, institutional approaches to the management of collaborative research lag behind the policy rhetoric. The paper concludes with an overview of the key dilemmas for institutional strategists and policy makers posed by the shift towards more collaborative approaches to research.  相似文献

The introduction to this article discusses a dilemma facing many Third World countries: should they place computers in their schools and, if so, for what purposes? The author outlines four common rationales—the Social, Vocational, Pedagogical and Catalytic—and refers to two less common ones—the Information Technology Industry and Cost-effectiveness Rationales. The main text describes policy in China at national level, and analyses policy and practice in Beijing City and Zhejiang Province. The paper is based on an international co-operative study of computers in African, Asian and Arabic- speaking schools, funded by the Harold Macmillan Trust.  相似文献

Co-production occurs when two or more institutions contribute funds and labour to the processes of making course components for distance teaching. The author summarises reasons for international co-production of multimedia distance-teaching courses and provides a checklist of questions that should be considered before entering upon such co-production.
The second half of the article consists of a composite case study based on the UK's Open University experience of international co-production. The paper ends with three questions: Is international co-production of this kind worth trying? Can the chances of success be made high enough by careful planning to justify risking capital in such ventures? Are other forms of collaboration more likely to be cost-effective?  相似文献
