This study aims to determine the effect of the STEM-integrated (Science, Technology, Engineering, and Mathematics) Problem-Based Learning (PBL) model assisted by e-LKPD on students’ critical thinking skills in ecosystem material at SMA Negeri 1 Kota Gajah. This research employed a quasiexperimental design using a pretest-posttest non-equivalent control group design. The subjects of this study were 72 tenth-grade students selected from a population of 432 students using purposive sampling technique. The data collection techniques consisted of quantitative data in the form of essay tests to measure students’ critical thinking skills and qualitative data in the form of student response questionnaires. The results showed that the use of the STEM-integrated PBL model assisted by e-LKPD had a significant effect on students’ critical thinking skills, as indicated by the Independent Sample T-test with a Sig. (2-tailed) value of 0.00 < 0.05 and an effect size of 0.89, which falls into the large category. The experimental class obtained an average N-gain score of 0.64 (moderate category), which was higher than the control class with an N-gain of 0.28 (low category). Based on the results of the student response questionnaire, a percentage of 86.46% was obtained, which is categorized as very high. Therefore, it can be concluded that there is a significant effect of the STEM-integrated PBL model assisted by e-LKPD on students’ critical thinking skills. Keywords: Critical Thinking, e-Worksheet, Problem-Based Learning, STEM (Science, Technology, Engineering, and Mathematics)
