今年も，世界授業研究学会（World association of Lesson Study，WALS）の年次大会で発表する。今年は，インドネシアのバンドゥンのIndonesia University of Educationで開催される。我々の報告は，11月26日午後のセッションと，本日，確認できた。そのタイトルは，「Study on the Factors for Sustainable Development of the School-based Practical Researches: With usage of the Theories on Professional Learning Communities (PLCs)」である。高知大学の島田先生，長崎大学の寺嶋先生とここ数年進めている，学校研究の継続・発展要因に関する研究の成果の一端を報告する。
In Japan, lesson studies are so popular, which are core activities of School-Based Practical Researches (SBPRs). SBPRs in Japan are defined as a series of research-oriented activities conducted by teachers at the same school. They enrich practical knowledge and reconstruct their belief system through not only lesson studies but also other activities of SBPRs such as making portfolios on their teaching, holding practical conferences for teachers from other schools and so on. However, teachers in Japanese schools have difficulties in making SBPRs sustainable. To clarify the factors for sustainable development of the SBPRs in Japanese schools, firstly, in 2011, the authors made interviews with leading teachers to get information on their efforts to revitalize SBPRs extending for more than one year at three elementary schools and one junior high school, using theories on PLCs. The data indicated that there were 4 factors for sustainable development of the SBPRs at those schools. Secondly, to confirm the reliability of those factors on sustainable development of the SBPRs, the authors made interviews with leading teachers and supervisors about SBPR efforts extending for a few years at another 3 elementary schools. The authors clarified the existence of the fifth factor for the SBPRs development named “Looking for Evidence to Use for Teacher Empowerment”. As a conclusion, the authors suggested the structural model of the factors for the sustainable development of SBPRs in consideration with the relationship among the 5 factors.
