This study aims to evaluate the effectiveness of mathematics learning that integrates the STEAM approach based on Bugis-Makassar local wisdom in improving students' conceptual knowledge competency, increasing students' learning activities, and forming positive responses from students. The research method used is pre-experimental research with a pretest-posttest design. Students from elementary junior high schools in the Bugis-Makassar region of South Sulawesi, Indonesia are involved in a learning program that combines local cultural elements in the context of STEAM. Data were collected through conceptual knowledge competency tests, observation of learning activities, and student response questionnaires. The results showed that the integration of local wisdom in STEAM learning significantly improved students' conceptual understanding of mathematics, increased more interactive and involved learning activities, and formed positive responses to learning. These findings indicate that a local culture-based approach not only enriches the learning experience but also has a positive impact on mathematics learning outcomes. This study contributes to the development of more relevant and effective learning strategies by considering the cultural context of students.
