Abstract
Rendahnya kemampuan pemecahan masalah matematis siswa sekolah dasar menjadi perhatian penting dalam dunia pendidikan abad 21, di mana keterampilan berpikir kritis dan pemecahan masalah sangat dibutuhkan. Berdasarkan hal tersebut, penelitian ini dilakukan untuk menganalisis pengaruh model Problem Based Learning (PBL) terhadap kemampuan pemecahan masalah matematis siswa sekolah dasar. Penelitian ini menggunakan pendekatan kuantitatif dengan desain kuasi eksperimen nonequivalent control group design. Populasi yang diambil dalam penelitian ini adalah seluruh siswa kelas V di salah satu SDN di Kabupaten Purwakarta, adapun sampel dari penelitian ini adalah siswa kelas VA dan VC di salah satu SDN di Kabupaten Purwakarta tahun ajaran 2024/2025 dengan total sampel 50 orang. Kelas eksperimen diberi perlakuan dengan menggunakan model Problem Based Learning (PBL), sementara kelas kontrol diberi perlakuan dengan menggunakan model Kooperatif Tipe Student Teams Achievement Divisions (STAD). Data dikumpulkan melalui instumen tes uraian pretest dan posttest yang disusun berdasarkan indikator Polya. Hasil analisis menunjukkan adanya peningkatan kemampuan pemecahan masalah matematis secara signifikan pada siswa yang mengikuti pembelajaran dengan model Problem Based Learning (PBL). Temuan ini membuktikan bahwa model Problem Based Learning (PBL) efektif dalam meningkatkan kemampuan pemecahan masalah matematis siswa sekolah dasar. ----- The low mathematical problem-solving ability of elementary school students has become a major concern in 21st-century education, where critical thinking and problem-solving skills ae essential. Based on this issue, this study aimed to analyze the effect of the Pproblem Based Learning (PBL) model on elementary school students’ mathematical problem-solving abilities. The research employed a quantitative approach with a quasi-experimental non-equivalent control group design. The population taken in this study were all fifth grade students in Purwakarta Regency. The sample of this study was VA and VC grade students at one of SDN in Purwakarta Regency in the 2024/2025 academic year with aa total sample of 50 people. The experimental class received treatment using the problem Based Learning (PBL) model, while the control class was taught using the Cooperative Type Student Teams Achievement Divisions (STAD) model. Data werw collected through pretest and posttest essay test based on Polya’s problem-solving indicators. The analysis showed a significant improvement in student’s mathematical problem-solving abilities in the Problem Based Learning (PBL) class compared to conventional instruction. These findings demonstrate that the Problem Based Learning (PBL) model is effective in enhancing mathematical problem-solving skills among elementary school students.
