Abstract

Ketidaksesuaian antara tuntutan pembelajaran matematika yang menekankan pemecahan masalah dengan rendahnya Self-efficacy dan kemampuan siswa, khususnya pada topik peluang, menunjukkan perlunya pendekatan pembelajaran yang lebih kontekstual. Penelitian ini bertujuan untuk: (1) mengetahui apakah peningkatan kemampuan pemecahan masalah siswa yang mendapat Problem-Based Learning (PBL) lebih tinggi secara signifikan dibandingkan dengan pembelajaran langsung, (2) mengetahui apakah peningkatan Self-efficacy siswa yang mendapat PBL lebih tinggi secara signifikan, dan (3) menganalisis hubungan signifikan antara peningkatan Self-efficacy dan kemampuan pemecahan masalah siswa yang mengikuti PBL. Penelitian menggunakan metode kuasi eksperimen dengan desain pretes-postes nonequivalent control group. Populasi adalah seluruh siswa kelas IX di salah satu SMP Negeri di Kota Bandung, dengan dua kelas sebagai sampel: kelas eksperimen (PBL) dan kelas kontrol (pembelajaran langsung). Instrumen berupa tes dan nontes. Hasil penelitian menunjukkan bahwa PBL secara signifikan meningkatkan kemampuan pemecahan masalah dan Self-efficacy siswa dibandingkan pembelajaran langsung. Namun, tidak ditemukan hubungan signifikan antara peningkatan Self-efficacy dan kemampuan pemecahan masalah pada siswa yang mengikuti PBL. Penelitian ini merekomendasikan penerapan PBL secara bertahap untuk meningkatkan kualitas pembelajaran matematika. The mismatch between mathematics learning demands—which emphasize problem-solving—and students' low Self-efficacy and abilities, especially in the topic of probability, highlights the need for a more contextual learning approach. This study aims to: (1) determine whether the improvement in students' mathematical problem-solving abilities using Problem-Based Learning (PBL) is significantly higher than those with direct instruction, (2) examine whether students' Self-efficacy improves more significantly with PBL, and (3) analyze the relationship between Self-efficacy and problem-solving improvement among students taught with PBL. The study used a quasi-experimental method with a pretest-posttest nonequivalent control group design. The population consisted of all ninth-grade students at a public junior high school in Bandung, with two classes as samples: the experimental class (PBL) and the control class (direct instruction). Instruments used included tests and non-tests. Results show that PBL significantly improves both problem-solving ability and Self-efficacy compared to direct instruction. However, no significant relationship was found between Self-efficacy and problem-solving improvement in the PBL group. The study recommends a gradual implementation of PBL to enhance the quality of mathematics learning.
