The development of the international lesson study community as a knowledge creating organization

本研究的主要目的是发展国际课程研究社区，目的是：(1)通过教师参与社区来发展教师教育体系；(2)研究参与国际社区对日本教师发展的影响。这一目标是通过国内研究活动和国际合作两个阶段实现的。在国内的研究活动中，我们通过跨越彼此原有实践社区的边界，发展了教师、教育工作者和研究人员的混合社区。我们运用设计研究方法来开发这样一个混合社区，使我们能够认识到在教育实践中实践者和研究者之间的无形冲突。在国际合作方面，我们参加了国际组织，各国教师以学习为知识建设的理念，为新课程实践的发展做出贡献。我们通过我们的设计学习方法提出的教案与其他国家的研究人员和实践者进行了讨论，以发展他们自己的课堂教学实践。研究界教师的经验使他们从新的哲学角度反思自己的实践，并形成了他们对学生学习的认识论。

The grand goal of the research was to develop the international lesson study community for the following purposes : (1) to develop the teather education system through their participation in the community, and (2) to investigate how the participation in the international community affect on the development of teachers in Japan. The goal was attained through the two phases : domestic research activity, and international collaboration. In the domestic research activity, we developed the hybrid community of teachers, educators, and researchers by crossing borders among each other's original community of practice. The design study approach we applied to develop such a hybrid community enabled us to recognize invisible conflicts between practitioners and researchers in educational practices. In the international collaboration, we participated in the international organization where teachers in different countries contribute to the development of new lesson practices with the philosophy of learning as knowledge building. Our proposal on lesson plans through our design study approach was discussed with researchers and practitioners in other countries to develop their own lesson practices in the dassroom. Experiences by teachers in our research community made them to reflect on their own practices from a new philosophical point of view, and to develop their epistemology on student learning.
