Abstract

This study aims to comprehensively analyze the effect of the Project Based Learning model on students' mathematical creative thinking abilities in Indonesia in 2021-2025. This study used a meta-analysis method with PRISMA guidelines and obtained 13 primary studies for analysis. Primary studies that met the inclusion criteria were analyzed using Comprehensive Meta-Analysis (CMA) software version 4.0. The results of the calculation of the overall effect size obtained a Hedges'g value of 1.063 with a Z value of 7.990 and a p value <0.05, which means that the application of the Project Based Learning model has a significant effect on students' mathematical creative thinking abilities. Based on the results of the moderator variable analysis, a very large effect size was obtained at the high school level with a Hedges'g value of 1.487 and in studies with a small sample size (≤30 participants) with a Hedges'g value of 1.121. However, the heterogeneity test between groups obtained a p value>0.05 for both moderator variables, so that the differences between groups were not statistically significant and did not provide sufficient evidence that education level or sample size moderated the intervention effect.
