Problem-Based Learning versus STAD Leaning Model for Improving Students' Argumentation Skills in Thermochemistry Tyas, Frida Kristining Dasna, I Wayan Wijaya, Anugerah Ricky Setyowati, Istri This study investigates whether the use of the Problem-Based Learning (PBL) model and Cooperative learning STAD can improve argumentation skills in the thermochemistry chapter. The research sample is 72 grade 11 high school students. The research design was quasi-experimental with a pretest-posttest control group design. The results of the study: (1) there was no difference in initial ability between the PBL and CL STAD classes with a significance value of > 0.00; (2) there are differences in argumentation skills between PBL and CL STAD classes with a significance value <0.00; (3) the PBL model N-Gain test was 60.50% in the "quite effective" category and CL STAD was 41.97% in the "less effective" category. Therefore, the PBL model is more effective in improving students' argumentation skills.  Keywords: problem based learning, STAD learning model, argumentation skills, thermochemistry.DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp298-308 FKIP Universitas Lampung 2025-05-02 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/264 Jurnal Pendidikan MIPA; Vol 24, No 1 (2023): Jurnal Pendidikan MIPA; 298-308 2685-5488 1411-2531 eng https://jpmipa.fkip.unila.ac.id/index.php/jpmipa/article/view/264/172 Copyright (c) 2025 Frida Kristining Tyas, I Wayan Dasna, Anugerah Ricky Wijaya, Istri Setyowati https://creativecommons.org/licenses/by-sa/4.0
