Meta-Analysis of the Influence of Problem-Based Learning (PBL) Learning Model on the Improvement of Creative Thinking Skills

Learning mathematics is an essential aspect of education, from elementary to tertiary levels.One effective method of teaching mathematics is Problem Based Learning (PBL).To determine the extent of the influence of implementing the PBL method on creative thinking skills in mathematics, the author collected 86 articles from various sources such as Google Scholar, Portal Garuda, and Sintaristekbrin.This study used a meta-analysis method to combine the findings from these articles.After analyzing all the collected articles, only 10 articles met the inclusion criteria and were analyzed using the meta-mar website to measure the combined effect of PBL implementation.Based on the interpretation of the combined effect size, it can be concluded that overall, the implementation of PBL has a moderate influence on mathematics learning by enhancing creative thinking skills.The study also examined factors such as educational level, year of research, region, and sample size used in the studies.Based on statistical analysis, the research indicated that the application of PBL to students' creative thinking skills is influenced by these factors, such as educational level, year of research, and sample size.
