家庭科の授業を行う小学校教師のPCKに関する研究: 若手教師と熟練教師の教師知識に関する比較研究

In this study, the author examined elementary school teachers’ Pedagogical Content Knowledge (PCK) in home economics lessons by comparing the knowledge base of novice teachers and that of experienced teachers. PCK is one among the knowledge bases for teaching as proposed by L. Shulman. First, the author defined PCK and teachers knowledge base by analyzing essential literature to conduct empirical research based on L. Shuman’s proposition. Second, the author examined PCK in home economics of four novice elementary teachers and three experienced elementary teachers by organizing semi-constructed interviews. From the results of the theoretical and empirical research, the author identified that PCK is a complex knowledge based on teacher knowledge, and that experienced elementary teachers’ PCK may differ considerably both in quality and quantity from that of novice elementary teachers. Therefore, experienced teachers can effectively teach in diverse contexts. The author believes that the conceptualization of PCK can be a powerful tool for understanding home economics teaching in elementary schools and be a useful point of view for reestablishing in-service teacher programs as well as pre-service teacher programs.
