ABSTRACT 

Physics learning in grade X of senior high school often faces low student participation and poor learning outcomes, particularly in the topic of measurement. This indicates the need for innovative learning strategies that actively engage students. This study aims to improve student activity and learning outcomes through the implementation of the Problem-Based Learning (PBL) model combined with crossword puzzles. This classroom action research was conducted in class X of SMA Negeri 5 Jember involving 35 students. The learning process was carried out over two meetings in two cycles. Each cycle consisted of planning, implementation, observation, and reflection stages. The results showed that the application of PBL with crossword puzzles improved students’ learning outcomes. The N-Gain score increased from 0.60 (moderate category) in the first cycle to 0.76 (high category) in the second cycle. Students' learning activity also improved from the "fair" to the "active" category. Therefore, the implementation of the PBL model combined with crossword puzzles was proven to be effective in enhancing student engagement and learning outcomes in the topic of measurement.
