初中数学教师课堂提问的方式和反馈水平实证研究——基于三位教师课堂录像的编码分析

Study on the Characteristics of the Way to Questioning and Feedback Level ——Based on Video Analysis of Lessons of Three Teachers

课堂提问是教学过程中师生之间进行思想交流的重要方式，直接影响着课堂教学的效果．目前初中数学教师课堂提问主要存在提问的数量和频次偏多，提问的类型不均衡，提问留给学生的思考时间过短及提问反馈形式的有效性不足等问题．可以采取合理控制课堂提问的频数，有效控制课堂提问的难度和适时调控提问的等候时间及综合运用反馈的应答方式等策略解决．

Classroom questioning is the most important way which communicate ideas between teachers and students in the teaching process. It directly affects the effect of classroom teaching. But there are still some main problems about classroom questioning in current junior high schools. For example, The number and frequency of questions, unbalanced question types, waiting time is too short to ask a question, the validity of questions the feedback form. Its solutions are as follows： controlling reasonably the frequency of classroom questioning, controlling effectively the difficulty of classroom questioning, timely regulation of waiting time of asking questions and the integrated use of feedback response type.
