The aim of this research was to investigate the effect of problem-based learning on students’ beliefs about physics and learning physics. The research design is quasi-experimental, non-equivalent control group design with samples were senior high school students grade XI at SMAN 1 Jambi City. The research used the Colorado Learning Atttudes About Science Survey (CLASS). Through data analysis using ANCOVA Test can be seen that there was no significant result effect of problem-based learning on students’ beliefs about physics and learning physics. The study’s finding indicates that students’ beliefs about characteristic and obtaining knowledge are difficult to change. Nonetheless, the use of various learning models that focus on the formation of the model building on the physics world through problem solving that are contextual and real, as well as providing opportunities for students to actively engage in problem solving can help students develop the belief that they have about the physics from novice-like belief into expert-like belief.Penelitian ini bertujuan menginvestigasi pengaruh penggunaan model pembelajaran berbasis masalah terhadap belief siswa tentang fisika dan pembelajaran fisika. Desain penelitian kuasi eksperimen non-equivalent control group design dengan sampel siswa kelas XI Sekolah Menengah Atas Negeri (SMAN) 1 Kota Jambi. Instrumen penelitian yang digunakan adalah kuesioner the Colorado Learning Attitudes About Science Survey (CLASS). Hasil uji Ancova terlihat bahwa tidak ada pengaruh signifikan penggunaan model pembelajaran berbasis masalah terhadap belief siswa tentang fisika dan pembelajaran fisika. Temuan penelitian mengindikasikan bahwa belief siswa tentang karakteristik dan cara memperoleh suatu pengetahuan sulit untuk diubah. Meskipun demikian, penggunaan berbagai model pembelajaran yang berfokus pada pada pembentukan model (model-building) dari dunia fisika melalui pemecahan masalah-masalah yang bersifat kontekstual dan nyata, serta memberikan kesempatan siswa untuk aktif terlibat dalam pemecahan masalah dapat membantu siswa mengembangkan belief yang mereka miliki tentang fisika dari belief sebagai seorang pemula (novice-like belief) menjadi belief sebagai seorang ahli (expert-like belief).

Pandemi COVID-19 mengakibatkan pembelajaran dilaksanakan secara daring, guru tetap mengembangkan kemampuan pemecahan masalah siswa. PBL dan PjBL dilaksanakan dengan aplikasi Zoom Cloud Meeting membuat siswa dapat mengkonstruksi ide penyelesaian masalah. Tujuan penelitian untuk melihat perbedaan kemampuan pemecahan masalah siswa yang diajarkan dengan PBL dan PjBL secara daring berdasarkan self efficacy, melihat interaksi antara pembelajaran PBL, PjBL, self efficacy terhadap kemampuan pemecahan masalah siswa. Desain penelitian menggunakan quasi experimental non-equivalent control group design, dengan populasi seluruh siswa kelas XI IPA SMA N 5 Kota Jambi, dengan teknik pengambilan sampel yaitu simple random sampling didapat 2 kelas eksperimen dan 1 kelas kontrol. Instrumen penelitian yaitu tes, angket, dan lembar observasi. Hasil penelitian diuji dengan ANOVA dua arah, menunjukan terdapat perbedaan kemampuan pemecahan masalah siswa yang memiliki self efficacy tinggi, sedang, rendah yang diajarkan dengan PBL dan PjBL, namun tidak terdapat iteraksi antara pembelajaran PBL dan PjBL dengan self efficacy siswa terhadap kemampuan pemecahan masalah. Hal ini dikarenakan, sesuatu yang telah dimiliki oleh setiap individu siswa sebelum diberikan perlakuan dan metode pembelajaran oleh guru tidak ada interaksi nya terhadap kemampuan pemecahan masalah matematika siswa, karena siswa sudah memiliki keyakinan (self efficacy) didalam dirinya masing-masing untuk menyelesaikan suatu masalah sebelum diberi materi ajar dengan suatu metode pembelajaran.
