Abstract

Abstract: Active student involvement is highly crucial in the current mathematics learning process. The objective is to shift material mastery from mere procedural memorization towards a more essential conceptual understanding. Therefore, this quantitative research is designed to examine how the application of the Student Teams Achievement Divisions (STAD) cooperative learning model impacts the development and improvement of phase F students' mathematical concept understanding. This study combines descriptive and quasi-experimental methods with a nonequivalent posttest-only control group design. The research population includes eleventh grade students (Phase F) at SMA Negeri 13 Padang. Through a simple random sampling technique, class F.5 was selected as the experimental group applying the STAD model, while class F.6 served as the control group with direct learning. Data collection was conducted through quizzes and a final test instrument. The quiz evaluation results demonstrated good progress across all indicators of students' conceptual understanding. Furthermore, the final test hypothesis testing using the t' test yielded a P-value of 0.000 < 0.05, which means that  is rejected. In conclusion, the implementation of the STAD cooperative learning model provides a significant positive impact in building students' mathematical concept understanding compared to the direct learning method. Keyword: mathematical concept understanding; STAD model; phase F mathematics.   Abstrak: Keterlibatan peserta didik secara aktif sangat krusial dalam proses belajar matematika saat ini. Tujuannya adalah agar penguasaan materi bergeser dari sekadar menghafal langkah-langkah prosedural menuju pemahaman konsep yang lebih esensial. Oleh sebab itu, riset kuantitatif ini dirancang untuk mengkaji bagaimana penerapan model kooperatif Student Teams Achievement Divisions (STAD) berdampak pada perkembangan dan peningkatan pemahaman konsep matematika peserta didik di Fase F. Penelitian ini mengombinasikan metode deskriptif dan quasi-experiment dengan pendekatan nonequivalent posttest-only control group design. Populasi riset mencakup peserta didik kelas XI (Fase F) di SMA Negeri 13 Padang. Melalui teknik simple random sampling, kelas F.5 terpilih sebagai kelompok eksperimen yang menerapkan STAD, sementara kelas F.6 menjadi kelompok kontrol dengan pembelajaran langsung. Pengumpulan data dilakukan melalui instrumen kuis serta tes akhir. Hasil evaluasi kuis memperlihatkan adanya progres yang baik pada seluruh indikator pemahaman konsep peserta didik. Selanjutnya, pengujian hipotesis tes akhir menggunakan uji t' menghasilkan nilai P-value sebesar 0,000 < 0,05, yang berarti  ditolak. Kesimpulannya, implementasi model kooperatif STAD memberikan dampak positif yang signifikan dalam membangun pemahaman konsep matematika peserta didik jika dibandingkan dengan metode pembelajaran langsung. Kata kunci: pemahaman konsep matematis; model STAD; matematika fase F.
