基于课例研究的实践共同体对外语教师专业发展影响的案例研究

The Influence of the Community of Practice Based on Lesson Study onTeachers’Professional Development:A Case Study

本研究聚焦高校与中学英语教师组成的长期性课例共同体,探索该共同体对外语教师专业发展的影响机制及理论启示,并构建基于共同体实践的教师专业发展模型。本研究的数据来自质性访谈、教师反思日志、课堂观察和共同体实践过程的话语。数据分析采用主题分析和话语分析。研究发现,课例共同体有助于优化外语教师的专业理念、增长专业知识、提升专业能力。教师以共同体的行动目标为导向,以交互参与为核心介质、以共享智库为坚实依托、以意义协商为动力保障,在“调节—内化—转变”的过程中实现专业发展。

The study focuses on the long-term community of lesson study formed by college and middle school English teachers,to explore the influence mechanism and theoretical implications,and to construct a model of teacher professional development.The data of the study are constituted of qualitative interviews,teacher reflective journals,classroom observations,and discourses of the community of practice.The study adopts thematic analysis and discourse analysis to analyze the data.The results show that lesson study community can improve teacher competences regarding their perception,knowledge and skills.Teachers achieve professional development during the process of“regulate-internalize-transform”,with the action goals of the community as the consistent guidance,the mutual engagement as the core medium,the shared repertoire as the solid bases,and the reproductive cycles as the guarantee of change.
