One of the problems faced by students in this study is their lack of ability to think critically. They also face difficulties in remembering and understanding the subject matter, do not have a strong desire to participate in learning, and are not active during the learning process. Combining the PjBL, PAKEM, and Collaborative learning models is an effort to overcome this problem. The purpose of this study was to analyze how teacher activities, student activities, and student learning outcomes can be improved in quality. Classroom action research was conducted in three meetings with a qualitative approach. Grade 4 students of SDN Alalak Utara 3, totaling 29 students, consisting of 13 male students and 16 female students, were involved in the study during the second semester of the 2023/2024 academic year. Data were collected by observing teacher and student activities, as well as student learning outcomes. Classical learning completion indicators and percentage scales were used to calculate data analysis. The results showed that project-based learning models, PAKEM, and collaborative learning can be used to improve student learning outcomes. Teachers showed increased activity at the third meeting by obtaining a score of 33 in the "very good" category, and students showed increased activity at the third meeting by obtaining a score of 86% in the "very active" category. At the third meeting, students' summative learning outcomes increased with a classical completion of 90%. Based on the results of this study, it can be concluded that using the Project-based learning, PAKEM, Collaborative learning models can improve the quality of student activities and learning outcomes. The suggestion for principals, teachers and other researchers is that this study can be used as a reference in using learning models that can improve student activities and learning outcomes.
