 note = {In this study, based on the Global Lesson Study (GLS) program, a mathematics lesson study was conducted between teachers in Japan and Singapore, with Singapore as the host school. During the GLS process, the childrenʼs ideas̶diff ered greatly between the two countries̶were shared, and the lesson plans were improved to move toward integrated learning, which could not have been conceived during the in-school research discussions in Singapore, and then, the improvements were refl ected in the lessons. This suggests that GLS is eff ective in improving the teaching of Mathematics.},
