Ziaun Nisa. 2025. The Effect of Problem Based Learning Model on Critical Thinking Ability and Collaboration Skills of 15 Adidarma Banda Aceh High School Students. Thesis. Faculty of Teacher Training and Education, Syiah Kuala University. Under the guidance of Dr. Saminan, M.Pd, and Mawarni Saputri, M.Pd. Critical thinking and collaboration skills are important 21st-century skills, but the results of the PISA 2022 survey show that students' critical thinking skills are still low, including at SMA 15 Adidarma Banda Aceh. This study aims to analyze the effect of the problem-based learning model on students' critical thinking and collaboration skills. The method used is quantitative with a Nonequivalent Control Group design. The research subjects consisted of two grades XI, namely the experimental class with the problem-based learning model and the control class with the discovery learning model. The research instruments were essay tests (pretest and posttest) to measure critical thinking and observation sheets to assess collaboration skills. Data on critical thinking skills were analyzed using the Independent Sample t-test, while collaboration skills were analyzed using a percentage test which showed a very good category. The results of the study showed a significant difference in critical thinking skills between the experimental and control classes (t_count 1.800 > 1.684t_table). Thus, the problem-based learning model has an effect on the critical thinking and collaboration skills of students at SMA 15 Adidarma Banda Aceh.
