The Application of an Ethnomathematics Approach Based on Jumputan Fabric in Teaching Plane Geometry in Grade IV Mathematics at MI Ihsaniyah 01 Debong Tengah

Abstract

This study aims to describe the implementation of an ethnomathematics approach based on kain jumputan (traditional tiedye fabric) in teaching two-dimensional shapes in Grade IV mathematics at MI Ihsaniyyah 01 Debong Tengah. This study employed a qualitative approach using a descriptive method. The research subjects consisted of students from Classes IV A and IV B at MI Ihsaniyyah 01 Debong Tengah, as well as teachers and university students involved in the mathematics learning process. Data were collected through observation, documentation, and an exhibition of students’ work. The findings indicate that kain jumputan can be used as a learning medium and context for introducing twodimensional shapes through the motifs, patterns, forms, and geometric arrangements found in the resulting fabric. Students were able to identify various twodimensional shapes and relate them to the mathematical concepts being studied. The implementation of the ethnomathematics approach based on kain jumputan also created a learning environment that was more contextual, engaging, and creative, while encouraging active student participation. In addition to understanding mathematical concepts related to two dimensional shapes, students gained experience in recognizing and appreciating local culture. An ethnomathematics approach based on kain jumputan can serve as an alternative for teaching twodimensional shapes in Grade IV at MI Ihsaniyyah 01 Debong Tengah.
