A teacher must be able to choose a learning model that has the potential to enhance students understanding of a concept. The purpose of this research is to determine the effects of Discovery Learning (DL) and Problem-Based Learning (PBL) models on the conceptual understanding of junior high school students regarding the material on simple machines. Additionally this study aims to compare the differences in understanding between students taught using these two models. This quasi-experimental research employs a nonequivalent pretest-posttest control group design involving two groups of eighth-grade students from a junior high school in Malang Regency for the 2024-2025 academic year. The sampling method used is cluster random sampling. The instruments applied in this study were multiple-choice tests. Several statistical procedures including normality tests homogeneity tests independent sample t-tests paired samples t-tests and N-Gain tests were utilized to analyze the data. The results indicate that both Problem-Based Learning and Discovery Learning positively affect students conceptual understanding. However learning through PBL resulted in a higher percentage of N-gain (%) in understanding at 70.22% compared to the Discovery Learning group which achieved 55%. Based on these findings it can be concluded that the use of DL and PBL can enhance students understanding of concepts and encourage them to participate more actively in the learning process.
