Research on the Strategies of Constructing Video Case Resources for Teachers’ Professional Development

教学视频案例作为一种能够有效实现教师实践性知识可视化与教师隐性知识外显化的资源，在教师教育和教师专业发展中具有重要作用。为突破传统课堂实录式的课例视频所存在的时间跨度长、主题不突出、使用不方便等问题，本文在系统分析视频案例资源在教师专业发展中的主要优势及建设要求的基础上，结合“微课”建设理念与TPACK知识框架提出了视频案例资源微型化与结构化建设思路，并深入探讨了以课程知识点、教学方法与信息化学科工具为粒度单位的视频案例资源建设策略。面向教师专业发展的视频案例资源建设策略探析

Teaching video cases， a kind of resource which can visualize a teacher’s practical knowledge and externalize the teacher’s tacit knowledge， play an importance role in teacher education and teachers’ professional development.
