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

本研究以发展国际课程研究共同体为主要目标，目的在于：（1）通过共同体的参与，促进教师教育体系的发展;（2）探讨国际共同体的参与对日本教师发展的影响。这一目标是通过两个阶段实现的：国内研究活动和国际合作。在国内研究活动中，我们通过跨越彼此原有的实践共同体的边界，发展了教师、教育工作者和研究人员的混合共同体。设计研究的方法，我们应用到开发这样一个混合社区，使我们能够认识到无形的冲突之间的从业者和研究人员在教育实践。在国际合作方面，我们参加了一个国际组织，在这个组织中，不同国家的教师以学习作为知识构建的哲学为新的课程实践的发展做出了贡献。我们通过设计研究方法提出的课程计划建议与其他国家的研究人员和从业人员进行了讨论，以在教室中开发自己的课程实践。我们研究共同体的教师的经验使他们从一个新的哲学角度反思自己的实践，并发展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.
