Abstract

Penelitian ini memiliki tujuan untuk mengetahui apakah peningkatan kemampuan pemecahan matematika yang diajar menggunakan model Problem Based Learning lebih tinggi daripada pembelajaran konvensional, apakah peningkatan Self-Efficacy yang diajar menggunakan model Problem Based Learning lebih tinggi daripada pembelajaran konvensional, interaksi antara kemampuan awal matematika siswa dan model pembelajaran terhadap peningkatan kemampuan pemecahan matematika, interaksi antara kemampuan awal matematika siswa dan model pembelajaran terhadap peningkatan Self-Efficacy siswa. Jenis penelitian kuantitatif dengan quasi eksperimen. Subjek dari penelitian adalah siswa kelas VIII SMP Negeri 3 Aek Kuo tahun ajaran 2022/2023. Hasil penelitian menunjukkan bahwa Peningkatan kemampuan pemecahan masalah matematis siswa yang diajar menggunakan model Problem Based Learning lebih tinggi daripada yang diajar dengan pembelajaran konvensional. Kemampuan Self-Efficacy siswa yang diajar dengan model Problem Based Learning lebih tinggi daripada dengan pembelajaran konvensional. Terdapat interaksi antara kemampuan awal matematika siswa dan model pembelajaran terhadap peningkatan kemampuan pemecahan masalah matematis siswa dapat dilihat berdasarkan uji hipotesis melalui uji t dan uji f yang masing-masing mendapat skor nilai sig model pembelajaran 0,000 < 0,05 dan nilai nilai thitung > ttabel yaitu 4,795 > 2,008. Terdapat interaksi antara kemampuan awal matematika siswa dan model pembelajaran terhadap peningkatan Self-Efficacy siswa. Dibuktikan berdasarkan uji hipotesis melalui uji t dan uji f yang masing-masing mendapat skor nilai sig model pembelajaran 0,004 < 0,05 dan nilai thitung > ttabel yaitu 3,450 > 2,008.

Abstract

This research aims: (1) to determine whether problem-based learning models improve mathematical problem-solving abilities and self-efficacy; (2) to explore the interaction between students' initial mathematical abilities and the learning model. The study employed a quasi-experimental quantitative design, with ANOVA used for inferential data analysis. Fifty eighth-grade students from SMP Negeri 3 Aek Kuo in the academic year 2022/2023 were examined. The null hypothesis (H0) was accepted, and the alternative hypothesis (Ha) was rejected since the significant F-test value was 0.178 > 0.05, and the T-test value was 0.692 > 0.05, indicating no significant difference in the average scores between experimental classes I and II. PBL students demonstrated better performance in answering mathematical problems compared to those in the direct learning group. Experimental class 1 achieved a mastery level of 84%, while experimental class 2 achieved a mastery level of 64%. PBL learners exhibited higher self-efficacy compared to those learning through direct instruction. Hypothesis testing indicated that students in experimental class 1 had stronger confidence in mathematical problem-solving compared to students in experimental class 2. The problem-based learning (PBL) methodology did not have a significant impact on students' mathematical problem-solving abilities. Hypothesis testing using interaction analysis yielded a significance value of 0.730 > 0.05. Both PBL and students' basic mathematical abilities influenced self-efficacy. Interaction analysis indicated a significance value of 0.000 < 0.05.Keywords: Problem based learning, early math skills, math solving, self efficacy
