This study presents compelling evidence of the effectiveness of Problem-Based Learning (PBL) in enhancing critical thinking skills among students at Manado State Polytechnic. Through a mixed-methods approach, including pre-test/post-test questionnaires and statistical analysis, significant improvements in critical thinking abilities were observed following engagement in PBL-based learning activities. Descriptive statistics revealed substantial increases in mean scores for problem-solving abilities, analytical reasoning, and creativity among participants from the pre-test to the post-test. Paired-samples t-tests confirmed these improvements as statistically significant, highlighting the robustness of the findings. The results hold important implications for educational practice, suggesting that PBL offers a promising approach for cultivating essential skills required for academic and professional success. By promoting active learning, collaboration, and higher-order thinking processes, PBL enhances students' critical thinking abilities and fosters their motivation and engagement in the learning process. Educators at Manado State Polytechnic and beyond can leverage these findings to inform the design and implementation of PBL-based learning experiences that effectively promote critical thinking skills among students. Further research is warranted to explore additional factors influencing the effectiveness of PBL and its long-term impact on students' learning outcomes. In summary, this study contributes to the literature supporting the adoption of innovative pedagogical approaches, such as PBL, to meet the evolving needs of twenty-first-century learners. By embracing PBL, educational institutions can empower students with the critical thinking skills necessary to navigate complex challenges and succeed in an increasingly dynamic and interconnected world.
