<![CDATA[Students often struggle to coordinate multiple mathematical representations when solving contextual problems, particularly in learning linear equations. This study aimed to develop and evaluate a representation-oriented instructional design integrated within an RPG Maker MV environment to enhance eighth-grade students' representational skills in learning Systems of Linear Equations in Two Variables (SLETV). The study employed the ADDIE model and involved 29 eighth-grade students from a private junior high school in Cirebon. Data were collected through expert appraisal, observations, interviews, questionnaires, and pretest–posttest assessments. Expert appraisal indicated that the design was valid (mean score: 3.78 on a five-point scale), while student responses confirmed its practicality. Following implementation, the mean representation score increased from 49.31 to 82.41 (reported N-gain = 0.67, moderate gain). Improvements were observed across verbal and symbolic representation indicators, whereas visual representation requires further targeted scaffolding. Overall, the findings suggest that aligning instructional activities with game mechanics offers a promising framework to supporting students' mathematical representation, offering a practical contribution to digital game-based pedagogy in mathematics education.]]>
