Meta-Analysis: The Influence of The Problem-Based Learning Model on Environmental Problem-Solving Ability

Abstract

Several experimental studies related to Problem Based Learning on environmental problem solving abilities have been carried out by previous researchers. This research aims to test how large the effect size is and to determine the impact of the Problem Based Learning model on the ability to solve environmental problems. The type of research carried out was meta-analysis, namely a narrative review by analyzing the results of previous research publications. The 11 study articles tested revealed that overall the Problem Based Learning model obtained an effect size value of 1,665, which is in the high effect category. Judging from the characteristics of the research, the Problem Based Learning model has an influence in terms of level of study, but does not have an influence in terms of year of research, number of samples and duration of study. The conclusion of this research is that the Problem Based Learning model is able to improve environmental problem solving abilities, as well as having a positive impact on learning that is integrated into environmental problems.
