学科教学知识（PCK）的结构特征及发展路径分析——基于小学数学教师的案例研究

Analysis on Structure Characteristics and Development of Pedagogical Content Knowledge: Cases from Mathematics Primary Teachers

This PCK description framework was built on Park’s PCK pentagon model and the conceptual illustration from Shulman. PCK Structure of Elements Map(PCK-SoEM) of four primary mathematics teachers were drew according to this framework. Generally， there’re two types of characteristic of PCK structure investigated， which are integrative style and deficient style. The former one could be inflexible and automatically. The latter one could be inattentive and inefficient. In view of these characteristic， reasons were analyzed accordingly. Furthermore， reflection and exploration were given through this PCK structure and characteristic. Based on the results， teachers could improve their PCK through follow strategy， which are setting up scientific teaching belief and orientation， thoroughly understanding students， paying more attention to subject knowledge structure and its representation， fully thinking and integrating the knowledge of PCK.
