The Evaluation of Problem-Based Learning Model Towards High School Students’ Critical Thinking Skills: A Meta-Analysis Study in Indonesia

Abstract

ABSTRACT This study aims to see the effectiveness of applying PBL (Problem Based Learning) models in Indonesian High School students’ mathematical critical thinking skills that are based on the series of similar studies. This study uses a meta-analysis method from a number of national scholarly journal articles indexed by Google Scholar, Semantic Scholar, Garuda Portal, DOAJ, ERIC and direct URL from the national journals published between 2012-2019 based on inclusion criteria. The statistical data processing used Comprehensive Meta-Analysis (CMA) V3 software. The results of the study based on the random effect model shows that the combined effect size is 1.201 with large effect criteria. It means that the application of the PBL model significantly has a greater effect on students' mathematical critical thinking skills than the application of conventional models. In addition, there are four study characteristics that are used in the analysis such as; research class, type of research school, year of research and sample size. There were significant differences in the application of the PBL model to students' mathematical critical thinking skills in terms of years of research based on the study characteristics. Meanwhile, from the research class, type of research school and sample size implicate no difference in the effect of applying the PBL model between the study groups. The findings unveil the effectiveness of using the PBL model in mathematical learning that is based on the study characteristics.
