Abstract

Problem-solving ability is a key competency in mathematics education, yet studies indicate that this skill remains low among vocational high school students. This study aims to develop and evaluate the feasibility of an educational RPG game, “Mathvestor,” designed using the Contextual Teaching and Learning (CTL) approach and Polya’s problem-solving stages for teaching simple and compound interest. The research employed an R&D method using the ADDIE model. Media validity was assessed by material and media experts, while practicality was evaluated through student questionnaires, teacher responses, and classroom implementation observations. The validation results indicated a “very valid” category, with scores of 94% for material and 91% for media. Practicality tests also showed a “very practical” category based on student responses (88%), teacher responses (94%), and implementation observations (88.8%). These findings demonstrate that Mathvestor is feasible and effective as an interactive and contextual learning medium to support students’ mathematical problem-solving skills.
