Meta Analysis: The Effect of Problem-Based Learning Model on Mathematical Critical Thinking Skills

This study aims to determine the effect of problem-based learning (PBL) model on students' mathematical critical thinking skills. This research reviews the effect of problem-based learning (PBL) model on students' mathematical critical thinking skills as a whole and based on education level. This research is a meta-analysis research. The data sources in the study came from the analysis of 10 national articles published in the range 2020-2024. Data sources in the study were obtained from google scholar. The research method used in this research is meta-analysis using OpenMEE software with the keywords used, namely problem-based learning and mathematical critical thinking. Based on meta-analysis calculations, that there is a relationship between the effect of problem-based learning models on mathematical critical thinking skills, from this study obtained an effect size of 1.527 which is included in the high category, p-value <0.001 means the analysis is significant and I^2 above 80% which indicates that the heterogeneity of the effect of problem-based learning models on mathematical critical thinking skills is 91, 542 including very high. Keywords: Meta analysis, Critical Thinking, Problem Based Learning (PBL)
