网络课程群知识建构研究：促进跨课程的网络学习

随着校本网络课程、国家精品课程、视频开放课程等不断涌现，门数众多、形式多样、内容交叉的网络课程需要联系起来、相互支持，以促进跨课程的网络学习。这就要求课程建设者打破传统课程内容的归属性，将内容紧密联系的网络课程作为课程群来进行建设。网络课程群是指使用计算机技术和互联网实现的本专业或跨专业培养方案中若干门在知识、方法、问题等方面有逻辑联系的课程加以整合而成的网络课程体系。基于知识建构的网络课程群能够整合不同网络课程的知识，优化网络课程教学活动，支持学生跨课程的网络学习和教师专业发展。目前我国网络课程群研究在理论层面多是面向具体学科的经验总结，在实践层面多关注具体案例，尚未洞察不同课程之间的知识关联。为了提升网络课程群的整体效益，网络课程群知识建构需要从分析框架、模型建构、促进策略、支持系统和评价方式等方面展开研究。网络课程群建设应根据经济社会的需求制定明确的目标，组建跨学科的研究团队，应用知识建构理论，采用定性与定量结合的方法，深入研究网络课程群知识建构过程的理论与实践问题。

Research on Knowledge Construction of Network Curriculum Group：Promoting Online Learning across the Curriculum

As the school-based curriculums, national fine-designed curriculums and video open curriculums constantly emerged, it is needed to connect and support each other in order to promote online learning across the curriculum. In this case, curriculum builders are required to break the traditional attribution of the curriculum content, and connect online curriculums whose contents are close related as a group. Online curriculum group refers to the integration of several curriculums which are related in the aspects of knowledge, methods and issues with the help of the computer technology and the Internet. The network curriculum group based on knowledge construction can integrate the knowledge of different network curriculums, optimize network curriculum teaching activities, and support both students＆#39; online learning across the curriculum and teachers＆#39; professional development. Current research on network curriculum group at the theoretical level focused on summary of experience in specific subjects, and at the practical level paid more attention to particular cases. However, the knowledge relationship between different curriculums has not been studied yet. In order to improve the overall effectiveness, the research on knowledge construction of network curriculum group should be carried out from the following perspectives：the analytical framework, the model research, the promotion strategy, the support system, the evaluation method and so on. The construction of network curriculum group should make clear objectives according to the economic and social needs, build an interdisciplinary team, and then by applying the theory of knowledge construction, deeply study the theoretical and practical problems in the knowledge construction of network curriculum group with the combination of qualitative and quantitative methods.
