Ethnomathematics Food Traditional Kicimpring: Designing and Validation Worksheets to Deepen Understanding of Direct Proportion Concepts

Abstract

Students experienced difficulties in understanding the basic concept of direct proportion and relating this concept to everyday contexts. This study aims to develop ethnomathematics-based worksheets using the traditional Sundanese food kicimpring to improve junior high school students' understanding of direct proportion in a valid manner. This study used the research and development method with a 4D model that included define, design, develop, and disseminate. The research instruments used were validation sheets by lecturers and mathematics teachers as well as practicality questionnaires by students. The results of the study showed an average validation of 96.4% (highly valid). This shows that an ethnomathematics-based worksheet using traditional Sundanese food, kicimpring, to improve the understanding of the concept of direct proportion in junior high school students is valid and feasible to continue further research on its effectiveness.
