Development of ethnomathematics-based e-modules to improve student learning outcomes on circle material

This study aims to develop an e-module on grade XI circle material based on Sawah Lodok ethnomathematics as a representation of the local wisdom of the Manggarai community with the help of the Canva application. This e-module development uses the Research and Development (R&D) model with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) approach. The findings showed that the developed e-module was declared valid and practical by expert validators and practitioners and received positive responses from students. The effectiveness test showed a significant increase in student learning outcomes after using the e-module. The ethnomathematics-based e-module on circle material developed is effective in improving student learning outcomes. This e-module successfully integrates the mathematical concept of circles with relevant local cultural contexts, thus making learning more meaningful and easier for students to understand. The practical implication of this research is the availability of alternative innovative teaching materials that can be used by teachers to create more engaging and interesting mathematics learning. This e-module can also be a reference for curriculum developers to develop similar teaching materials on other mathematics topics, while still paying attention to the potential of ethnomathematics in local culture.
