Ethnomathematics integrated realistic mathematics education to improve students' interpersonal intelligence

This study aims to examine the feasibility and efficacy of learning mathematics using Realistic Mathematics Education (RME) and ethnomathematics to enhance students' interpersonal intelligence. Students from SMP Nur Azizi in North Sumatra, Indonesia, are the subjects of this study. In this study, media development was done through design research. Data collection strategies were implemented using questionnaires. This study employed expert validation sheets and interpersonal intelligence questionnaire sheets as its instruments. Based on data analysis, it was determined that: 1) Mathematics learning through ethnomathematics integrated RME was declared valid or feasible to be applied in mathematics learning to improve students' interpersonal intelligence based on expert validation with a score of 37.5 (valid); 2) The dimensions of interpersonal intelligence achieved include discussion (social communication) and cooperation (social sensitivity). Therefore, it can be concluded that learning mathematics using ethno-mathematics integrated RME is effective for use in the learning mathematics process
