Abstract

This research aims to explore the stages of Homo Batu culture towards school mathematics learning. This research was conducted in South Nias, North Sumatra Province. The type of research is ethnomathematics, namely analysis of the stages carried out by a fahombo. The research instrument uses interview and observation sheets. Qualitative data analysis is used to explore the stages carried out by a fahombo in learning mathematics. Based on the results of exploration and analysis, it can be concluded that the fahombo stages can be applied as stages of mathematics learning, namely (1) practice solving questions in the easy, medium, and (2) difficult categories, (3) solving questions in the medium and difficult categories, (4) ) completing routine questions and mathematics application questions, and (5) measuring abilities with quizzes.

Abstract

This study aims to develop a Project-Based Learning (PjBL) module integrated with ethnomathematics by utilizing Nian Gao (Chinese New Year cake) as a cultural artifact representing the geometric concept of a cylinder to enhance junior high school students’ conceptual understanding of solid geometry. The study employed a Research and Development (R&D) approach using the ADDIE model, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The participants were junior high school students in Kelapa Gading, North Jakarta, Indonesia. Data were collected through expert validation sheets, student response questionnaires, classroom observations, interviews, and pre-test and post-test assessments. The data were analyzed using descriptive qualitative and quantitative methods based on mean scores and percentage analysis. The results revealed that the developed learning module obtained an average expert validation score of 4.56, indicating that it was highly feasible for classroom implementation. The implementation of the PjBL module actively engaged students in observing, measuring, and identifying the geometric elements of a cylinder through hands-on exploration of Nian Gao. This contextual learning approach significantly improved students’ conceptual understanding of solid geometry, enhanced their learning engagement and spatial reasoning, and encouraged meaningful learning experiences. Furthermore, integrating ethnomathematics into mathematics instruction fostered students’ appreciation of Chinese Indonesian cultural heritage, thereby supporting both mathematics learning and character education. Therefore, the developed ethnomathematics-based PjBL module is an effective and feasible instructional resource for promoting meaningful, contextual, and culturally responsive mathematics learning.
