Students of Mathematics Education are mathematics teacher candidates who must have various competencies before becoming a teacher. These competencies are obtained through the learning process at the university. Many ways can be done to develop student pedagogical skills at the university. One of them is through lesson study. This research aims to figure out the effectiveness of lesson study in improving the competence of mathematics pre-service teachers. The competency is developing a lesson plan based on ethnomathematics. The ethnomathematics used in this study is limited to the culture in Yogyakarta and its surroundings, namely Prambanan Temple, Borobudur Temple, and Yogyakarta Palace. The research sample was 6th-semester pre-service teacher of the Mathematics Education Study Program of Yogyakarta State University in the 2018/2019 academic year. This research is a quasi-experimental study with the design of Pretest-Posttest One-Group. The instrument of data collection uses an assessment sheet. Data on the results of the lesson plan assessment were analyzed using the one-sample test. The results of the study at a significance level of 5% showed that the implementation of Lesson Study was effective in terms of student competence in developing a lesson-plan based on ethnomathematics. © International Journal of Scientific and Technology Research.
