Abstract

This study aims to explore the ethnomathematics concepts in Apang, a traditional cake of the Bugis people, focusing on applying geometric concepts and cultural values embedded in its production and presentation processes. Using an ethnographic approach, data were collected through observation, interviews, and documentation. The results show that Apang incorporates geometric plane concepts, such as triangles and rhombuses, as seen in the shape and molds of the cake. Additionally, the steaming vessel for Apang is cylindrical with a conical lid, reflecting the application of solid geometry in traditional tools. Apang also embodies the cultural values of the Bugis community, including togetherness, simplicity, gratitude, and patience. It is often served during traditional events such as thanksgiving ceremonies, Menre Bola Baru, and Ramadan traditions. Thus, this study not only reveals the application of mathematical concepts in daily life but also enriches the understanding of the interaction between culture and mathematics within the Bugis community.

Abstract

The Think Pair Share (TPS) learning model aligns with the conditions of the Merdeka Curriculum. However, the application of this model is still limited and has not been widely measured through students' mathematical problem-solving ability and self-efficacy. Therefore, this study compares the effectiveness of the Think Pair Share (TPS) learning model and direct learning in improving students' mathematical problem-solving ability and self-efficacy. This study used a quantitative method with a Pre-test, Post-test Nonequivalent Control Group research design. The research subjects were taken through purposive sampling, involving two classes as samples. Class VIII D applies the Think Pair Share (TPS) learning model, and class VIII F uses direct learning. Data were obtained from pretest, posttest and questionnaire results. The collected data were then analyzed using the Independent Sample t-test and Pearson product-moment correlation test with a significance level of a = 0.05. The results of the analysis show that the significance value for mathematical problem-solving ability and student self-efficacy is below 0.05. It can be concluded that the Think Pair Share (TPS) learning model affects students' ability to understand, plan and solve a mathematical problem and can increase student self-efficacy based on this research.
