The Influence of Problem-Based Learning Models on Middle School Students' Understanding of Mathematical Concepts

Abstract

This study aims to analyze the effect of problem-based learning (PBL) models on students' understanding of mathematical concepts in high school. PBL emphasizes real-world problem-based learning that encourages students to think critically, analyze, and solve problems independently. This study used a quasi-experimental design with two groups, namely the experimental group implementing PBL and the control group using conventional learning methods. The results showed that the implementation of PBL significantly improved students' understanding of mathematical concepts, as evidenced by the significant difference between the posttest scores of the experimental group (82.7) and the control group (74.2). In addition, students who learned using PBL also showed higher involvement in discussions and exploration of concepts. These findings provide evidence that PBL is effective in improving understanding of mathematical concepts and can be used as an alternative in mathematics learning in high schools. However, challenges in implementing PBL, such as teacher readiness and time constraints, need to be addressed with adequate training and provision of resources.
