PENGEMBANGAN ROLE-PLAYING GAME UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR MATEMATIS SISWA PADA MATERI BARISAN DAN DERET ARITMETIKA

Students often experience difficulties in mathematical thinking, particularly in the processes of specializing, generalizing, conjecturing, and convincing when learning arithmetic sequences and series. These difficulties are mainly reflected in students’ limited ability to provide logical reasoning and to justify the correctness of their solutions. Meanwhile, research on the development of educational Role-Playing Games (RPGs) to support students’ mathematical thinking in Indonesian contexts remains limited. Therefore, this study aimed to develop an educational Role-Playing Game entitled Arithmetic Adventure: The Mystery of Polaria Village and to examine its validity, practicality, and effectiveness in enhancing students’ mathematical thinking abilities. This study employed a development research approach using the ADDIE model, which consists of the stages of analysis, design, development, implementation, and evaluation. The model was selected due to its systematic and iterative structure, allowing continuous refinement of the developed product. The participants were 34 tenth-grade students of SMA Negeri 10 Palembang. Data were collected through expert validation, student practicality questionnaires, and mathematical thinking ability tests. The data were analyzed using descriptive and inferential statistics, including a paired-sample t-test and effect size calculation. The results indicated that the developed media achieved a validity level of 91.19%, categorized as very valid. Practicality testing showed that Arithmetic Adventure 1 obtained a score of 86.25% and Arithmetic Adventure 2 achieved 87.08%, both categorized as very practical. Furthermore, the effectiveness test revealed a significant improvement in students’ mathematical thinking abilities, with the mean pre-test score increasing from 54.06 to 73.65 in the post-test. This improvement was statistically significant (p < 0.001) with a large effect size, indicated by a Cohen’s d value of 1.22.
