Development of InterFrac Matching Kit integrates game-based learning in the form 1 rational numbers topic

This study aims to develop InterFrac Matching Kit integrates Game-based Learning (GBL) in the Form 1 Rational Numbers topic which has a satisfactory validity and to determine the perspective of future teachers about the usability of teaching aids in InterFrac Matching Kit integrates GBL in the Rational Numbers topic among Form 1 students. This study uses design and development research while InterFrac Matching Kit is developed using ADDIE Model. There are two research instruments used in this study which are Evaluation Questionnaire for InterFrac Matching Kit and Perception of The Perspective of Future Teacher on Usability Questionnaire for InterFrac Matching Kit. The InterFrac Matching Kit is validated by three experts where the data are calculated using Content Validity Index. Respondents for this study are 50 future mathematics teachers chosen using simple random sampling. Data were analyzed descriptively and inferentially involving one sample t-test. The findings showed that the face and content validity of InterFrac Matching Kit are at a satisfactory level. Overall, the perception of the perspective of future teacher about the usability of teaching aids in InterFrac Matching Kit is positive. For future uses, teachers can alter this kit to be used in other topics. Hopefully, with the help of InterFrac Matching Kit, future teachers can help students to excel in Rational Numbers topic.
