Gamification of Mathematics Teaching Materials to Improve Problem Solving and Critical Thinking Ability: The Experts’ Assessment

Abstract

Gamification is a learning approach in which moving games or visualizations are specifically designed to teach certain skills to students so that the learning process motivates students to think and solve problems. The purpose of this study was to develop gamification-based junior high school mathematics teaching materials in the form of GEMAS games to improve problem-solving skills and mathematical critical thinking. This study uses the ADDIE model of research and development but is limited to only 3 stages, namely analysis, design, and development, as well as an assessment by a team of experts using the Delphi technique. The research instruments used were the validation sheet for the critical thinking ability test using FRISCO theory, the validation sheet for the problem-solving ability test instrument with the Krulik and Rudnick indicators, and the game validation sheet. Data were analyzed descriptively. Based on the results of content validity data analysis related to the GEMAS game that has been developed, it is found that the criteria in the context of problem-solving skills and critical thinking skills used are 90.20% fulfilled, and the fulfillment of game content criteria reaches 94%. Based on these data overall 92% of the GEMAS game feasibility assessment criteria have been met. Thus, the gamification-based teaching material in the form of the GEMAS game has been developed as an assessment in a very valid category and is suitable for use in learning
