This study aims to determine the Influence of the Project Based Learning (PJBL) Model in Improving Students' Critical Thinking Skills in the Fourth Grade PPKN Subject of SDN 15 Palu. The population in this study is 25 students in grade Four A for the 2024/2025 school year. Sampling uses saturated sampling techniques. The data collection technique uses Pretest and Posttest tests. Based on the results of the study on the Influence of the Project Based Learning (PJBL) Model in Improving Students' Critical Thinking Skills in the Fourth Grade PPKN Subject of SDN 15 Palu, the value of the hypothesis test paired sample T-Test Sig. (2 Tailed) 0.000 < 0.05, then Ho was rejected and Ha was accepted, meaning that the alternative hypothesis (Ha), namely the project-based learning (PJBL) model was effective in improving the critical thinking skills of fourth grade students of SDN 15 Palu was accepted. Meanwhile, the zero hypothesis (Ho), namely the project-based learning (PJBL) model, is not effective in improving the critical thinking skills of fourth grade students of SDN 15 Palu was rejected.
