Le résumé fourni par la source

This study aimed to determine the effect of using a Problem Based Learning (PBL)-based e-module on students’ critical thinking skills in ecosystem material at Grade X of SMA Negeri 2 Perbaungan. An experimental method with a pretest-posttest control group design was employed. The sample consisted of two randomly selected classes: an experimental group that used the PBL-based e-module and a control group that received conventional direct instruction. Data were analyzed using normality and homogeneity tests, followed by a Z-test. The results showed a Z-count of 3.22, which exceeded the Z-table value of 1.96 at the 5% significance level, indicating a significant difference between the two groups. Therefore, the PBL-based e-module had a significant effect on students’ critical thinking skills and can be considered an alternative instructional resource for Biology learning, particularly on ecosystem topics.
