Abstract


This study aimed to develop and evaluate the effectiveness of ISTOPAN, a manipulative and game-based learning media, in improving students' conceptual understanding of addition with regrouping and supporting their learning motivation. ISTOPAN was derived from the Indonesian concept "berhitung susun metode menyimpan" referring to a structured counting approach using the carrying (regrouping) method among first-grade elementary school students. The study employed a Research and Development (R&D) approach based on a simplified Borg and Gall model. The research subjects were first-grade students at SD Muhammadiyah 3 Gresik. Data were collected through questionnaires, classroom observations, interviews, and pre-test post-test assessments. Data were analyzed using descriptive qualitative and quantitative methods, supported by a paired-samples t-test to examine the effectiveness of the media. The result showed that ISTOPAN was valid, with validation scores of 95% from material experts, 94% from media experts, and 98% from learning experts. The initial field trial involving 8 students showed a response rate of 90%, with a significance value of 0.001 (< 0.05), indicating a significant improvement in students' understanding. The second field trial involving 17 students showed a response rate of 88.2%, with a significance value of 0.000 (< 0.05), confirming a statistically significant improvement in students' conceptual understanding. In addition, the findings indicates a positive impact on students' learning motivation, reflected in increased attention, interest, and active participation. In conclusion, ISTOPAN was valid, practical, and effective in improving conceptual understanding and supporting students' learning motivation.
