Abstract: The purpose of this study was to determine the contribution of realistic mathematics learning and ethnomathematics to mathematical communication skills. This research is a quasi experimental study using a 2x2 factorial design. The sample is 60 students, who are chosen with the whole group technique. The experimental class was given an ethnomathematics-based realistic mathematics learning approach, and a control class with a traditional approach. Data collection is done by using a mathematical communication ability test. Data were analyzed by ANCOVA. The result, if the two groups of students were given the ethnomathematics material, the students' mathematical communication skills were taught with a higher realistic learning approach used by traditional learning approaches.

Keywords: ethnomathematics, mathematical communication, realistic mathematics learning
