课堂教学情境下教师实践性知识生成机制研究

A Case Study of Generative Mechanism of Teachers' Practical Knowledge in the Classroom Teaching Context

采用质性研究中的个案研究方法,追踪H小学数学教师课堂教学活动,着重分析教师实践性知识在课堂教学情境中的生成机制。在文化—历史活动理论视角下,教师课堂教学情境中的实践性知识呈现为嵌套式生成机制。基于活动系统分析发现,教师子系统的能动性努力、学生子系统的支援性契机以及双方共同面对问题解决而形成的互动与协商,构成了教师实践性知识的运作过程。

Employing the case study method in qualitative research to record a mathematics teacher ＇ s teaching activity longitudinally, this paper focuses on the generative mechanism of teachers ’ practical knowledge in the classroom teaching context. In the perspective of cultural and historical activity theory, teachers ’ practical knowledge in the classroom teaching context is presented as an embedded generative mechanism. The activity system analysis finds that teachers ＇ active efforts,students ’ supportive opportunities and their interaction and negotiation in solving problems form the operating process of teachers ’ practical knowledge.
