This study uses a Classroom Action Research (CAR) approach which is implemented in two cycles, each including the planning, implementation, observation, and reflection stages with 30 students as subjects. The research instruments are in the form of learning outcome tests, observation sheets of student and teacher activities, and field notes. The results of the study showed a significant increase in learning completeness, namely from 33.3% in the initial test, increasing to 56.7% in cycle I, and reaching 86.7% in cycle II. In addition, student involvement in discussions, self-confidence, and critical thinking skills also experienced positive development. </em></p> Miranti Khairani I Nyoman Murdiana Mulianti Mulianti Copyright (c) 2025 Miranti Khairani, I Nyoman Murdiana, Mulianti Mulianti https://creativecommons.org/licenses/by/4.0 2025-09-11 2025-09-11 4 3 165 172 10.47662/jkpm.v4i3.1056 https://ejurnal.univamedan.ac.id/jkpm/article/view/1057 <p>Mathematics is often perceived as difficult by students due to its association with formulas and abstract concepts, leading to low motivation and learning outcomes. This condition was observed in class XI A3 of SMA Negeri 3 Palu, where most students had not yet achieved the Minimum Mastery Criteria (KKM) in statistics. This study aims to improve mathematics learning outcomes through the implementation of the Problem Based Learning (PBL) model combined with the Team Games Tournament (TGT) method. The research employed Classroom Action Research (CAR) involving 36 students of class XI A3, with data collected through tests, observation, and documentation. The findings revealed an improvement in average learning outcomes from 68.1% in the pre-cycle to 76.5% in cycle I, and 92.5% in cycle II. Learning mastery also increased from 33.3% in the pre-cycle to 69.4% in cycle I, and reached 88.8% in cycle II. Therefore, the implementation of PBL integrated with TGT proved effective in enhancing conceptual understanding, learner independence, and mathematics achievement.</p> Rizky Ramadhani Zubaer I Nyoman Murdiana Siti Hanifah Naim Copyright (c) 2025 Rizky Ramadhani Zubaer, I Nyoman Murdiana, Siti Hanifah Naim https://creativecommons.org/licenses/by/4.0 2025-09-25 2025-09-25 4 3 173 180 10.47662/jkpm.v4i3.1057
