Outline of Final Research Achievements

Two main results of this research are the followings.
(1) The authors designed an integrated framework of the two-axis process model of understanding mathematics for improving students’ mathematical understanding and the dynamic cycle driven by the dialectic cycle of two complementary reflections in the lesson study of school mathematics for promoting the professional development of mathematics teachers and educators. It is demonstrated that the integrated framework could improve the quality of secondary education in terms of students’ mathematical attainment and teachers’ professional development.
(2) The results of this developmental research on integration of research on mathematical understanding and mathematics lesson study exemplified and proposed a new authentic research area in the science of mathematics education in the world.
