Abstract

This study aims to determine the influence of the Problem Based Learning (PBL) learning model on the learning outcomes of junior high school students. This study uses an experimental method with a pre-test and post-test design on grade VIII students. The results showed that students who used the PBL model had higher learning outcomes compared to students who used the conventional learning model. The PBL model can improve student learning outcomes because students are given the opportunity to learn actively and independently. This research shows that the PBL model can be an effective alternative learning model to improve the learning outcomes of junior high school students. By using the PBL model, teachers can help students develop critical and creative thinking skills. This research is expected to be a reference for teachers and other researchers to develop more effective learning models.

Abstract

This study aims to analyze the differences and effects of problem-based learning, project-based learning, and direct instruction models on students’ critical thinking and mathematical problem-solving abilities. The research employed a quasi-experimental design with a pretest–posttest control group design. The population of the study consisted of all eighth-grade students of SMP Negeri 20 Rejang Lebong in the 2025/2026 academic year, totaling 83 students, and all were used as the sample through a total sampling technique. The research instruments were essay tests measuring critical thinking skills and mathematical problem-solving abilities, which had been tested for validity and reliability. Data analysis was conducted through normality tests, homogeneity tests, and one-way ANOVA with a significance level of 0.05. The results showed that the average posttest score of critical thinking ability in the project-based learning class (86) was higher than that in the problem-based learning class (83) and the direct instruction class (76). In terms of problem-solving ability, the highest average score was obtained by the problem-based learning class (87), followed by the project-based learning class (86) and the direct instruction class (81). The ANOVA test results indicated a significance value of 0.05, demonstrating that there are significant differences and effects among the three learning models on both abilities. It can be concluded that problem-based learning and project-based learning models are more effective than direct instruction in improving students’ critical thinking and mathematical problem-solving abilities
