Abstract
Today, one of the skill that student needed to be success in mathematics is problem-solving ability. As educators we are charged with the great challenge and responsibility of engaging students in learning so that they develop the skills and knowledge they need to function in todays world. Inquiry-based learning is an approach to teaching and learning that places students questions, ideas and observations at the centre of the learning experience. Lesson study (jugyo kenkyu) is an inquiry model of teacher professional development used extensively throughout Japan and has begun to capture the attention of the American educational community as a potential strategy for enhancing teacher professional development in America. There would be implemented inquiry-based learning through lesson study about composition function and inverse function to improve the students mathematical problem-solving ability and used tests and questioners to know the students improvement. In this research, there was an improvement of students mathematical problem-solving ability after implemented these methods. So, we could know that inquiry-based learning through lesson study were successful to improve the students mathematical problem-solving ability.
