Abstract

This study was motivated by the importance of mathematical representation ability in mathematics learning and the limited availability of learning media aligned with the Merdeka Curriculum. Interviews with a mathematics teacher at SMA Negeri 6 Mandau indicated that students had difficulty presenting data through images, graphs, or tables and using mathematical symbols and language to solve problems. This study aimed to develop GeoGebra-assisted student worksheets on systems of linear inequalities in two variables to facilitate the mathematical representation ability of Grade X senior high school students. The study employed a research-and-development approach using the 4-D model: define, design, develop, and disseminate. Data were collected using validation sheets completed by three expert validators and response questionnaires administered to 12 Grade X students with heterogeneous abilities. The validation produced a mean score of 3.68, categorized as highly valid, while the student-response questionnaire yielded a mean score of 3.50, categorized as highly practical. The final product was compiled as a student worksheet book. These findings indicate that GeoGebra-assisted worksheets can provide a technology-based alternative for supporting conceptual understanding and mathematical representation, although their effectiveness requires further testing with larger and more diverse samples.
