ETNOMATEMATIKA: EKSPLORASI KONSEP GEOMETRI DALAM KONSTRUKSI RUMAH ADAT BUTON SEBAGAI BAHAN PEMBELAJARAN MATEMATIKA SEKOLAH DASAR

Abstract

Geometry is the study of the relationship between points, lines, angles, planes and spatial figures. This study aims to explore the concept of elementary school geometry in the traditional house of the Buton people in Baubau City and describe the teacher's view of the results of the exploration. Transformative qualitative research uses multiparadigms, namely postmodern, critical, and interpretive. Data collection techniques used include writing as inquiry, postmodern interviews, and writing critical auto ethnography literature studies. The results showed that there is an elementary school geometry concept in the construction of traditional Butonese houses (including lines and angles, flat shapes, geometric shapes) and the geometric concepts contained in the Butonese traditional houses can be used as an alternative source of ethnomathematics-based mathematics learning (mathematics in local culture), can be used to deepen education and understanding of local culture to students and can be used as a fun source of educational material because it involves concrete and cultural objects found in Indonesia.
