技术助力教师教育视频资源的典型应用问题与发展趋势

To Promote the Development and Application of Educational Video Resources by Technology for Teacher Education

视频作为一种教育数字媒体,一直以来都是教育技术学研究的重要领域。视频运用于教师教育的发展经历了微格教学、交互分析、建模专家教学、基于视频案例的研究、超媒体项目5个阶段。每个阶段的发展都基于教学理论的发展与进步,而且在不同阶段视频资源的教育应用是并行兼用的。基于"跨越式优秀课例资源网"的调研发现,当前视频资源的教育应用存在视频内容粗加工、视频支持技术单薄和视频资源应用范畴有限三大典型问题,不利于教师教育的持续发展和学科领域的深入发展。在互联网技术和数字设备广泛普及的信息时代,技术的助力为视频资源的教育创新应用提供了更广泛的空间,也为解决当前存在的问题提供了可能途径。回顾和审视当前国内外有关教育视频资源开发与应用的技术及项目,可以发现,教育视频资源应从内容开发、活动设计、交互技术、语义技术、应用机制5个方面进行纵深发展,从而实现教师的深度有效学习和个性化协作学习,并促进教育视频研究的螺旋式发展。

Video, as a kind of educational resource, is an important research field of educational technology.With the change of teaching theory, educational video resources for teacher education go through five stages：microteaching, interaction analysis, modeling expert teaching, video-based cases and hypermedia programs.Different application types are syncretic. The survey of the ＂KUAYUE Lesson Resource Website＂ found that thereare three typical problems in video resources application, namely, simple content processing, simple relevanttechnology and limited application areas. With the wide spread of the internet technology and digital equipment inthe information age, to promote education video resources by technology not only provides a wider space for theeducation innovation and application, but also solves the existing problems. By reviewing the current domestic andinternational study, it can be found that the trend of further development in education video resources contains videocontent development, activity design, interaction innovation, semantic technology and application mechanism. Thenew development will realize deep learning and personalize collaborative learning, as well as promoting a spiral of change in educational video research for teacher education.
