Abstract


This study aims to analyze the geometric concepts embedded in Batak Toba ulos motifs, examine their philosophical meanings, and describe students' mathematical representation abilities through ethnomathematics-based geometry learning. The study employed a descriptive qualitative approach with an educational ethnography design. Participants consisted of 30 tenth-grade students at SMAN 11 Kota Tangerang and one Batak Toba ulos weaver selected purposively. Data were collected through observations, interviews, documentation, and student worksheets and analyzed using the Miles and Huberman model. The findings revealed that the motifs of Ulos Ragi Hotang, Ulos Sadum, and Ulos Bintang Maratur contain geometric concepts, including rectangles, triangles, rhombuses, lines, angles, symmetry, translation, and repetitive patterns associated with the values of order, harmony, continuity of life, and family relationships. Analysis of students' work indicated variations in visual, verbal, and symbolic mathematical representation abilities. These findings suggest that ulos cloth has the potential to serve as a contextual and culturally responsive resource for geometry learning while supporting the integration of ethnomathematics into mathematics education.
