Development of Crack the Code kit integrates game-based learning in the form 1 linear equations topic

This study focuses on developing Crack the Code Kit integrates game-based learning in the Form 1 Linear Equations topic with satisfactory validity and determining the perspective of future teachers about the usability of teaching aids in Crack the Code Kit among Form 1 students. This study uses design and development research (DDR) while Crack the Code Kit is developed using ADDIE Model. The sampling method is simple random sampling involving 50 respondents. The instruments for this study are the evaluation questionnaire and perception questionnaire. The validation data of three experts on Crack the Code Kit is analysed using the Content Validity Index (CVI). In contrast, the actual research findings are analysed by using one sample t-test. In sum, Crack the Code Kit achieves satisfactory validity (CVI = 1.0), has a positive perception from the respondents and can benefits teachers and students in the teaching and learning process of Linear Equations topic.
