Abstract

This research was aim to improve the students’ mathematics learning outcomes through realistic mathematics approach bases on ethnomathematics. This research was classroom action research that implemented at SMP Negeri 2 Nosu, consist of first cycle and second cycle. The subject of this research was the seventh-grade students of SMP Negeri 2 Nosu in 2021/2022 academic year with 15 students consist of 5 men students and 10 women students. The students’ score obtainable used instrument essay question. The data was analyze used descriptive statistics. Based on the research result for the first cycle and the second cycle show that pre- test score for the first cycle was 64.33 with standard deviation was 8.330 and the completeness was 46.67%. The students’ post-test score for the second cycle was 80.93 with standard deviation was 7.815 and score completeness was 93.33% that means fulfilled the classical completeness criteria that is 85%. Based on the result, can conncluded that the use of mathematics realistics approach bases on ethnomathematics can improve the students’ mathematics learning outcomes for the square submaterial.
