    Abstract

    Penelitian ini dilatar belakangi oleh kegiatan pembelajaran di sekolah yang masih kurangnya pemahaman konsep matematis siswa. penelitian dilakukan menggunakan model Problem Based Learning (PBL) berbantuan media papan pecahan untuk meningkatkan pemahaman konsep matematis siswa di SD. Penelitian ini menggunakan jenis penelitian kuatitatif, metode penelitian Quasi Eksperimen dengan desain Nonequivalent Control Group Design. Sampel digunakan yaitu siswa kelas IV A dengan jumlah 20 siswa sebagai kelas eksperimen menggunakan model Problem Based Learning (PBL) berbantuan media papan pecahan. Sedangkan kelas IV B dengan jumlah 20 siswa sebagai kelas kontrol menggunakan Cooperative Learning tipe STAD. Hasil penelitian menunjukkan peningkatan pemahaman konsep matematis siswa yang menggunakan Model Problem Based Learning (PBL) berbantuan media papan pecahan lebih baik dari pada siswa yang menggunakan Model Cooperative Learning tipe STAD dengan N-Gain kelas eksperimen 0,55 dan N-Gain kelas kontrol 0,48 yang berada pada kategori sedang dan terdapat pengaruh sebesar 28,7% untuk meningkatkan pemahaman konsep matematis siswa di SD. Kesimpulan dari penelitian ini yaitu pemahaman konsep matematis siswa kelas eksperimen yang mendapatkan model Problem Based Learning (PBL) berbantuan media papan pecahan lebih baik dari pada siswa yang mendapatkan model Cooperative Learning tipe STAD dan model Problem Based Learning (PBL) berbantuan media papan pecahan berpengaruh untuk meningkatkan pemahaman konsep matematis siswa di SD. ----- This research is motivated by the low level of students' mathematical conceptual understanding in elementary school learning activities. To address this issue, the study was conducted by implementing the Problem Based Learning (PBL) model supported by fraction board media, with the aim of improving students’ mathematical conceptual understanding. The type of research used is quantitative with a quasi-experimental method, employing a Nonequivalent Control Group Design.The research sample consisted of two classes: Class IV A as the experimental class with 20 students, which used the Problem Based Learning (PBL) model assisted by fraction board media, and Class IV B as the control class with 20 students, which used the Cooperative Learning model of the STAD type.The results showed that the increase in mathematical conceptual understanding of students in the experimental class was higher than that of the control class. The N-Gain score for the experimental class was 0.55, while the control class scored 0.48. Both scores fall into the moderate category, but the experimental class showed better results. Additionally, it was found that the Problem Based Learning model assisted by fraction board media had a 28.7% effect in improving students’ mathematical conceptual understanding. In conclusion, the application of the Problem Based Learning (PBL) model assisted by fraction board media is significantly more effective in enhancing students' mathematical conceptual understanding compared to the Cooperative Learning model of the STAD type.
