In this paper we describe a strand of activities for teachers of mathematics that we used with two cohorts of participants
in a professional development program called Revitalizing Algebra (REAL). We first discuss our goals and describe the participants,
and then we describe the construction and selection of the tasks followed by teacher responses. Finally, we reflect on different
iterations of the tasks, their impact on the teachers’ thinking and practice, and the role of school and department culture
in the process of change. 相似文献

It is contended that an academic discipline illustrates certain characteristics and functions. The question whether distance education, in its current state, reflects these characteristics is explored. 相似文献

Differential costs of curricula in Illinois public junior colleges: Some implications for the future
The purpose of this study was to determine and analyze the annual cost of operation including depreciation of movable capital equipment for educating one student in each curriculum of selected community colleges and to show the relationship of costs of vocational-technical curricula to the cost for common baccalaureate oriented curricula.A stratified sample of eight community colleges was drawn from those that had been in operation for at least five years.These data indicate that a majority of the courses offered in highly specialized curricula in both the occupational and baccalaureate categories were more expansive than those courses that were common to a wide variety of curricula.This study supports differential program funding to assure continued development of high quality vocational-technical programs in community colleges. 相似文献

Learning Analytics (LA) and adaptive learning are inextricably linked since they both foster technology-supported learner-centred education. This study identifies developments focusing on their interplay and emphasises insufficiently investigated directions which display a higher innovation potential. Twenty-one peer-reviewed studies are identified via a systematic review and classified based on the dimensions of a proposed framework. The findings of the review suggest that interesting work has been carried out during the last years on the topic. We conclude with a need for more research on the topic in specific learning domains and settings. Recommendations include: a clear strategy for adaptation augmented by LA, the combination of on-task with pre-task measures, and the combination of system-controlled adaptation with user-controlled adaptation. Future trends include the emergence of constructivist-collaborative environments that provide insightful models of complex student behaviour. 相似文献
