Abstract
Kemampuan pemecahan masalah siswa dalam pembelajaran fisika khususnya materi gelombang bunyi masih tergolong rendah. Salah satu upaya untuk mengatasi permasalahan tersebut dengan memilih model pembelajaran yang tepat. Pemberian scaffolding konseptual dalam penerapan model problem based learning (PBL) digunakan untuk melihat peningkatan kemampuan pemecahan masalah siswa pada materi gelombang bunyi. Metode yang digunakan yaitu kuantitatif dengan desain kuasi eksperimen nonequivalent control group. Sampel yang digunakan adalah 50 siswa dari dua kelas XI MIPA di salah satu SMA swasta di Kabupaten Bandung. Kelas eksperimen diberikan perlakuan berupa penerapan model PBL dengan scaffolding konseptual, sedangkan kelas kontrol hanya menerapkan model PBL. Instrumen tes yang digunakan yaitu soal esai yang mengacu pada empat indikator pemecahan masalah menurut Polya. Analisis yang digunakan adalah uji N-Gain, uji stacking, uji-t dan uji effect size. Berdasarkan rata-rata nilai N-Gain, menyatakan kelas eksperimen menghasilkan peningkatan kemampuan pemecahan masalah siswa lebih tinggi dibandingkan kelas kontrol dengan nilai sebesar 0,64 sementara di kelas kontrol sebesar 0,58. Pada uji stacking pun peningkatan kemampuan pemecahan masalah siswa di kelas eksperimen lebih tinggi dibandingkan dengan kelas kontrol dengan nilai rata-rata peningkatan logit sebesar 5,13 sementara di kelas kontrol sebesar 4,86. Lebih lanjut, hasil analisis uji t menyatakan bahwa adanya perbedaan yang signifikan antara peningkatan kemampuan pemecahan masalah siswa di kelas eksperimen dan di kelas kontrol. Perbedaan tersebut menunjukkan model pembelajaran yang diterapkan berpengaruh terhadap peningkatan kemampuan pemecahan masalah siswa. Melalui hasil analisis effect size menunjukkan pemberian scaffolding konseptual dalam model PBL yang diterapkan pada kelas eksperimen efektif dalam meningkatkan kemampuan pemecahan masalah siswa dengan perolehan nilai d yaitu 9,750 yang termasuk dalam kategori besar. Dapat disimpulkan bahwa penerapan model PBL dengan scaffolding konseptual dikatakan efektif dalam meningkatkan kemampuan pemecahan masalah siswa pada materi gelombang bunyi. Students' problem-solving skills in learning physics, especially sound waves, are still relatively low. One of the efforts to overcome these problems is by choosing the right learning model. Conceptual scaffolding in the application of problem based learning (PBL) model is used to see the improvement of students' problem-solving skills on sound wave material. The method used is quantitative with a quasi-experimental design of nonequivalent control group. The samples used were 50 students from two class of XI MIPA in one of the private high schools in Bandung Regency. The experimental class was given treatment of applying the PBL model with conceptual scaffolding, while the control class only applied the PBL model. The test instrument used was an essay question that refers to the four indicators of problem-solving according to Polya. The analysis used is N-Gain test, stacking test, t-test and effect size test. Based on the average N-Gain value, it states that the experimental class resulted in a higher increase in students' problem-solving skills than the control class with a value of 0.64 while in the control class it was 0.58. In the stacking test, the increase in students' problem-solving skills in the experimental class was higher than the control class with an average logit increase value of 5.13 while in the control class it was 4.86. Furthermore, the results of the t-test analysis stated that there was a significant difference between the improvement of students' problem-solving skills in the experimental class and in the control class. The difference shows that the learning model applied has an effect on improving students' problem-solving skills. Through the results of the effect size analysis, it shows that the provision of conceptual scaffolding in the PBL model applied to the experimental class is effective in improving students' problem-solving skills with the acquisition of a d value of 9.750 which is included in the large category. It can be concluded that the application of the PBL model with conceptual scaffolding is said to be effective in improving students' problem-solving skills on sound waves material.
