This study was conducted to address the low level of students’ critical thinking skills and learning outcomes in Science and Social Studies at the elementary school level. The purpose of this study is to determine the effect of the Project Based Learning model based on Science, Technology, Engineering, Arts, and Mathematics (STEAM) on students’ critical thinking skills and learning outcomes. This research employs a quantitative approach with a quasi-experimental design using a pre-test and post-test control group. The sample consists of fifth-grade students selected using a specific sampling technique. Data collection was carried out through test instruments to measure students’ critical thinking skills and learning outcomes. Data analysis was conducted using normality tests, homogeneity tests, and multivariate analysis. The results indicate that the Project Based Learning model based on Science, Technology, Engineering, Arts, and Mathematics (STEAM) has a significant effect on students’ critical thinking skills and learning outcomes. These findings suggest that integrated project-based learning can enhance students’ activeness and engagement in the learning process. This study emphasizes the importance of implementing innovative learning models to improve higher-order thinking skills and students’ academic achievement.
