基于语义wiki的网络课程设计与开发

Designing an Online Course Based on Semantic Wiki

目前我国大多数网络课程侧重在界面和美工方面的改进,而网络课程的核心要素即学习资源却相对静态固定,组织不灵活,重复利用率不高,缺乏语义关联信息。学生的学习更多只是对资源进行浏览和简单交互,缺乏深度互动,对资源建设的参与度低,主动学习的动机不高,学习效果不理想。针对这些问题,我们引入Web2.0群建群享的思想,提出了一种基于语义wiki的开放、灵活、可扩性网络课程设计思想,强调网络课程资源的群建、联通、共享的特性,并开发了一门网络课程进行探索性案例研究。实验结果表明,基于语义wiki的网络课程能促进师生、生生之间的协作交互,提高学生协作学习意识,并能在一定程度上提高学习效果。

Outstanding issues in most of the online courses in China are currently two-faceted: on the one hand,most attention is given to interface design and layout whereas the key component,the learning content itself,is not regularly updated,not flexibly organized,not used repeatedly enough,and short of semantic association and cross reference;on the other hand,students' learning remains at merely browsing the materials and simple interaction,without contributing to creating the learning materials,with low motivation and unsatisfactory learning result.An open,flexible and extendable web course design principle is adopted in a case study based on web 2.0,with emphasis on everybody-contributes,cross-referencing and sharing.The results show that online courses based on semantic Wiki can strengthen both teacher-to-student and student-to-student collaboration and interaction,enhancing students' learning collaborative learning consciousness,hence,to a certain extent,improving learning effectiveness.
