Abstract


Abstract This research is motivated by the low problem-solving skills of students in the kinetic theory of gases and the lack of innovation in the use of models in physics learning. Efforts made by researchers to overcome these problems are by applying a laboratory-based PBL learning model. The purpose of this study was to determine the effect of the laboratory-based PBL learning model on students' problem-solving skills on gas kinetic theory material in class XI IPA SMA Negeri 1 Cilimus. The research method used is a quasi-experimental research design with a pretest-posttest control group design. The results show that after the implementation of the laboratory-based PBL model, it is obtained that is tcount  more tha t table so that H0 is rejected, can be concluded that there is an influence of the laboratory-based PBL learning model on problem-solving skills in gas kinetic theory material in class XI IPA SMA Negeri 1 Cilimus.

 

Keywords problem-solving skills, problem based learning, laboratory activities, kinetic gas theory.

 

Abstrak Penelitian ini dilatar belakangi oleh rendahnya keterampilan pemecahan masalah peserta didik dalam materi teori kinetik gas dan kurangnya inovasi penggunaan model dalam pembelajaran Fisika. Upaya yang dilakukan Peneliti untuk mengatasi masalah tersebut adalah dengan menerapkan model pembelajaran Problem Based Learning (PBL) berbasis laboratorium. Tujuan penelitian ini adalah untuk mengetahui pengaruh model PBL berbasis laboratorium terhadap keterampilan pemecahan masalah peserta didik pada materi teori kinetik gas di kelas XI IPA SMA Negeri 1 Cilimus tahun ajaran 2021/2022. Metode Penelitian yang digunakan adalah quasi experiment dengan desain penelitian pretest-posttest control group desain. Hasil penelitian menunjukkan bahwa setelah diterapkannya model PBL berbasis laboratorium diperoleh thitung lebih dari t tabel sehingga H0 ditolak, dapat disimpulkan bahwa ada pengaruh model pembelajaran PBL berbasis laboratorium terhadap keterampilan pemecahan masalah pada materi teori kinetik gas di kelas XI IPA SMA Negeri 1 Cilimus.

 

Kata kunci: keterampilan pemecahan masalah, pembelajaran berbasis masalah, aktivitas laboratorium, teori kinetik gas.
