Abstract: This study examines the integration of Problem-Based Learning (PBL) and Student Teams Achievement Division (STAD) to improve students’ creative thinking, mathematical reasoning, and collaboration skills in trigonometry. Conducted at MA Ali Maksum Yogyakarta, the study involved 26 Grade XI Science 2 students using a one-group pretest–posttest pre-experimental design. Quantitative data were collected through tests and questionnaires, with observations as supporting data, and analyzed using paired-samples t-tests. The results showed significant improvements in creative thinking from 16.5 to 70.5, mathematical reasoning from 19.26 to 75.6, and collaboration skills from 57.1 to 74.7 (all p < .001). These findings indicate that integrating PBL and STAD effectively supports trigonometry learning. Abstrak: Penelitian ini mengkaji integrasi Problem-Based Learning (PBL) dan Student Teams Achievement Division (STAD) untuk meningkatkan kemampuan berpikir kreatif, penalaran matematis, dan keterampilan kolaborasi siswa pada materi trigonometri. Penelitian dilaksanakan di MA Ali Maksum Yogyakarta dengan melibatkan 26 siswa kelas XI IPA 2 menggunakan desain pra-eksperimen tipe one-group pretest–posttest. Data dikumpulkan melalui tes dan angket, dengan observasi sebagai data pendukung, kemudian dianalisis menggunakan uji paired-samples t-test. Hasil penelitian menunjukkan peningkatan signifikan kemampuan berpikir kreatif dari 16,5 menjadi 70,5, penalaran matematis dari 19,26 menjadi 75,6, dan keterampilan kolaborasi dari 57,1 menjadi 74,7 (seluruhnya p < 0,001). Temuan ini menunjukkan integrasi PBL dan STAD efektif mendukung pembelajaran trigonometri.
