Abstract

The purpose of this study is to investigate the effect of students' critical thinking skills in relation to the issue of global warming when using Problem-Based Learning (PBL) e-worksheets assisted by PhET. Students from classes X2 and X4 participated in this study, which was conducted at SMA Negeri 1 Seputih Raman during the odd semester of the 2023/2024 academic year. In this non-equivalent control group research design, the dependent variable is critical thinking skills, the moderator variable is the PBL model, and the independent variable is the PBL-based e-worksheet assisted by PhET. The study results indicate that the use of PBL-based e-worksheets assisted by PhET enhances students' critical thinking skills. This is confirmed by the n-gain test results, which show that the control class obtained a low score of 0.299, while the experimental class achieved a moderate score of 0.498. Additionally, the effect size test produced a score of 1.78, which falls into the very high category. In conclusion, compared to traditional video-based worksheets, PBL-based e-worksheets assisted by PhET have been proven to be significantly more effective in improving students' critical thinking skills.
