Abstract

This study aims to analyze the geometric forms found in the construction and surrounding area of the traditional house Bola Pa’borongan of the Kajang community in Bulukumba, South Sulawesi, and to examine its potential as a source of ethnomathematics-based learning in geometry instruction. The research employs a qualitative approach with an ethnographic method, using direct observation, interviews with traditional leaders, and document analysis related to the culture and architecture of the Kajang people. The results show that the Bola Pa’borongan house embodies various geometric concepts, including vertical, horizontal, parallel, and perpendicular lines; several types of angles; plane figures such as triangles, squares, rectangles, and trapezoids; solid figures such as rectangular prisms, pyramids, and cubes; as well as geometric transformations in the form of dilation and reflection that appear in the shape and proportions of the roof and the arrangement of architectural elements. These forms function not only structurally but also reflect philosophical values of simplicity, balance, and harmony with nature upheld by the Kajang community. The findings indicate that the Bola Pa’borongan traditional house has strong potential to be used as contextual learning media that helps students understand geometric concepts more meaningfully while fostering appreciation for local wisdom.

Abstract

Analytic geometry learning often emphasizes symbolic procedures, while students’ spatial visualization and geometric reasoning remain underdeveloped. This gap highlights the urgency of developing culturally contextualized learning materials that connect concrete spatial experiences with formal mathematical concepts. This study aims to develop and evaluate the effectiveness of a local wisdom-based analytic geometry module in improving students’ geometric thinking levels (GTL). The study employed Research and Development (R&D) using the ADDIE framework, comprising Analysis, Design, Development, Implementation, and Evaluation. Participants were 36 third-semester pre-service mathematics teachers at Universitas Negeri Makassar, selected purposively. Data were collected through module validation sheets, student response questionnaires, and a seven-item open-ended Geometric Thinking Test, and analyzed descriptively and using the Wilcoxon Signed-Rank Test. The module achieved high validity based on subject matter (0.92) and cultural (0.80) expert validation and high practicality (83.79%). Wilcoxon analysis indicated a significant improvement in GTL (Z = −5.233; p < 0.001). Students reaching Level 3 (Formal Deduction) increased from 0% to 69.4%, while 2.8% reached Level 4 (Rigor). Integrating traditional-house wireframes and weaving patterns provided visual-cultural scaffolding that bridged spatial intuition and formal algebraic reasoning. These findings demonstrate the module’s potential to strengthen formal geometric reasoning and support culturally responsive mathematics education. Future studies should examine its effectiveness using larger, diverse samples and comparative designs.
