促进实践反思的视频案例支持系统构建

摘要

现有教师实践反思方式无法客观全面记录课堂场景，只能按照时间顺序浏览录像带，受教师主观因素影响较大。随着技术条件的不断成熟，可以构建以视频注释和检索为核心的视频案例支持系统，让所有教师随时对视频内容进行检索、自动播放视频注释片段、定制个性化主题学习，更好地促进教师实践反思，进而提升教师专业能力。%Existing way of teachers practice reflection can't objective and comprehensive record classroom scene ,only view the tape in chronological order ,subjective factors influenced teachers ,as technology continues to mature condition ,now can build a video case support system with video annotation and retrieval as the core .Teachers at any time can make all video content retrieval ,auto-play video annotation clips ,custom personalized thematic learning ,to better promote the practice reflection ,and thus enhance the professional development of teachers .
