基于Transana 平台的教师专业发展可视化分析案例研究

A Case Study on the Visualized Analysis with Transana of Professional Development of Teacher

我国教师专业发展大都采用口头阐述和笔录方式进行定性描述，而对于教师专业发展的可视化分析比较少。文章利用国外的Transana平台，结合Flanders课程观察定量分析法，根据TIMSS─R课堂教学信息编码的两个维度对精品课程的一个视频课例进行分析，为执教教师提供一种可视化分析模式和平台。

Most of PDT（Professional Development of Teacher）is qualitatively described by means of interpretation and note─taking， but the fewest of PDT is visibly analyzed. Borrowing the platform of foreign Transana， according to the quantitative analysis of Flanders’ classroom observation， this paper analyzed a class video from a classic curriculum with two dimensions of class information encoded by TIMSS─R， with the intent to provide a visualized mode of analysis and a visualized platform for teachers.
