xMOOCs中的教学视频设计要点:基于案例的视频分析研究

Key Points of Instructional Videos Design in xMOOCs:Video Analysis Based on Cases

大规模开放网络课程(MOOCs)的发展得到了国际社会的广泛关注。在主流的两类MOOCs(cMOOCs与xMOOCs)中,xMOOCs是目前发展速度最快,受众面最广的一类。而教学视频是xMOOCs最核心的课程资源。xMOOCs中的教学视频设计应该把握哪些要点?为解决这一问题,特意分析了国内外四个主流课程平台的20门xMOOCs课程中的视频,参考《网络课程评价规范》形成视频分析框架,结合网络课程设计理论从界面设计、课程内容、教学设计三个方面对xMOOCs视频进行分析。根据视频分析结果,总结了xMOOCs教学视频在易识别性、课程说明、内容分块、学习目标、教学策略、学习者控制、内容交互性、信息呈现、练习与反馈九个方面的设计要点,并辅之以案例说明。希望对未来xMOOCs教学视频的设计有一定的参考与借鉴作用。

The development of Massive Open Online Courses （MOOCs） has attracted wide attention in international communi-ty. Nowadays, xMOOCs develop more rapidly and get wide attention in the two main MOOCs including xMOOCs and cMOOCs. Video is the key element of xMOOCs. Are there any experiences that can be learned from the existing videos design of xMOOCs？ 20 courses were chosen from four main platforms at home and aboard to analyze the characteristics of their videos based on the framework of the Design of e-Learning Course from nine aspects of easy identification, course description, content distribution, learning objectives, teaching strategies, learners control, content interaction, information presentation, exercises and feedbacks. Some valuable experiences are summarized with the framework of video analysis, which may have implications for future video design in xMOOC.
