One of the efforts made by the government is to change the learning approach that was originally teacher-centered to student-centered, the approach in question is scientific. This study tries to explore the implementation of lesson study using a scientific approach to improve the quality of mathematics learning in elementary schools. This research was conducted in an elementary school in Purwakarta. Based on the results of the study it was found that lesson study is an effective way to improve the quality of mathematics learning in elementary schools. the use of a scientific approach also has an impact on learning activities with five stages of scientific thinking, namely observing, asking, trying, reasoning, and communicating to stimulate students to be active and think critically.
