Susi Yanti: The Application of STEM-Based Project Based Learning Model to Improve Critical Thinking Skills and Learning Outcomes of Year X Students at MAS Darul Ihsan Supervisor I. Dr. Hafnati Rahmatan, M.Si, Supervisor II. Prof. Dr. M. Ali Sarong, M.Si ABSTRACT Students’ skills to analyze a problem in practicing critical thinking skills are poorly trained. Therefore, STEM-based project-based learning is used to improve the learning outcomes and students' critical thinking skills. This study aimed to determine the improvement of Year X students’ critical thinking skills and learning outcomes using STEM-based project-based learning on the topic of environmental pollution in MAS Darul Ihsan. This research is a quantitative research method with an experimental research approach. The research design used was a one-group pretest-posttest design. The population of this study was 159 Year X students in MAS Darul Ihsan. The sampling technique used a total sampling. The instrument used to measure critical thinking skills consisted of 30 reasoning multiple choice questions, and the instrument to examine the learning outcomes was 30 multiple-choice questions. Data were analyzed using the N-gain test and paired sample t-test at a significant level of 0.05. The results showed that the model of STEM-based project-based learning could improve Year X students' critical thinking skills on the topic of environmental pollution in MAS Darul Ihsan. It was also revealed that the model could enhance Year X students’ learning outcomes on the topic of environmental pollution in MAS Darul Ihsan. Therefore, it can be concluded that the model of STEM-based project-based learning can improve Year X students’ critical thinking skills and student learning outcomes on the topic of environmental pollution in MAS Darul Ihsan.
