    Abstract

    Kemampuan pemecahan masalah siswa, khususnya dalam mata pelajaran fisika masih tergolong rendah dan menjadi salah satu tantangan utama dalam proses belajar. Salah satu cara untuk mengatasi masalah ini adalah dengan menerapkan model pembelajaran yang sesuai. Dalam penelitian ini, diterapkan model Problem Based Learning (PBL) yang dipadukan dengan Scaffolding Metakognitif untuk melihat sejauh mana model tersebut dapat berpengaruh terhadap peningkatan kemampuan pemecahan masalah siswa pada materi gelombang bunyi. Penelitian ini menggunakan metode quasi-eksperiment dengan desain equivalent control group. Sampel terdiri dari 61 siswa kelas XI di salah satu SMA di Kota Bandung, yang dibagi ke dalam dua kelas. Kelas eksperimen mendapat perlakukan berupa penerapan model PBL dengan Scaffolding Metakognitif, sementara kelas kontrol hanya menerapkan model PBL saja. Instrumen berupa soal uraian yang dikembangkan berdasarkan empat indikator pemecahan masalah menurut Polya. Analisis data dilakukan melalui uji N-Gain, uji stacking, uji-t, dan uji effect size Cohen’s d. hasil analisis menunjukan bahwa peningkatan kemampuan pemecahan masalah siswa di kelas eksperimen lebih tinggi dibandingkan dengan kelas kontrol. Hasil uji independent t-test menunjukan terdapat perbedaan yang signifikan antara kedua kelas. Selain itu, hasil effect size menujukan bahwa penerapan model PBL dengan Scaffolding Metakognitif memiliki efektivitas sedang terhadap kemampuan pemecahan masalah dibandingkan penerapan model PBL saja. Dengan demikian, dapat sisimpulkan bahwa penerapan model Problem Based Learning dengan Scaffolding Metakognitif memberikan pengaruh besar terhadap peningkatan kemampuan pemecahan masalah siswa pada materi gelombang bunyi. Students' problem-solving abilities, particularly in physics, remain relatively low and represent one of the major challenges in the learning process. One way to address this issue is by implementing an appropriate learning model. This study employed a Problem-Based Learning (PBL) model integrated with Metacognitive Scaffolding to examine the extent to which this model influences the improvement of students' problem-solving skills in the topic of sound waves. The study used a quasi-experimental method with an equivalent control group design. The sample consisted of 61 eleventh-grade students from a senior high school in Bandung, divided into two classes. The experimental class received instruction using the PBL model with Metacognitive Scaffolding, while the control class was taught using only the PBL model. The instrument used was an essay test developed based on the four problem-solving indicators proposed by Polya. Data were analyzed using N-Gain, stacking test, t-test, and Cohen’s d effect size. The results indicated that the improvement in problem-solving ability in the experimental class was higher than in the control class. The independent t-test showed a significant difference between the two classes. Additionally, the effect size analysis revealed that the implementation of the PBL model with Metacognitive Scaffolding had a moderate effect on problem-solving abilities compared to the PBL model alone. Therefore, it can be concluded that the implementation of the Problem-Based Learning model integrated with Metacognitive Scaffolding has a big impact on enhancing students' problem-solving skills in the topic of sound waves.
