Validation of a Game-Based Chemistry Learning Module (KimCraft): Expert Review and Preliminary Findings

Chemistry is a core subject that plays an important role in developing students’ scientific literacy. However, abstract topics such as Matter and Atomic Structure often pose significant challenges, leading to misconceptions, low academic achievement, and negative attitudes toward learning chemistry. In line with Sustainable Development Goal 4 (SDG 4), a game-based learning module known as KimCraft was developed using Minecraft Education to support the teaching of this topic in a more interactive manner. The module was designed based on the ADDIE instructional design model and grounded in Vygotsky’s Social Constructivism Theory, which emphasizes collaborative learning and instructional scaffolding within the Zone of Proximal Development. This study aimed to evaluate the content validity of the module through expert review. A 23-item checklist was assessed by nine experts and analysed using the Content Validity Index (CVI). The findings showed that both the I-CVI and S-CVI/Ave achieved a value of 1.00, indicating excellent content validity. These results confirm that the KimCraft module is relevant, curriculum-aligned, and has strong potential to support more effective and engaging chemistry learning.
