Abstract


In the digital era, critical thinking skills are essential for students to navigate complex challenges. However, these skills in science education remain a concern. This study examines the effectiveness of discovery learning-based electronic worksheets (e-worksheets) integrating PhET simulations and animated videos in enhancing students' critical thinking skills. A quasi-experimental design with a nonequivalent control group was employed, involving 60 eighth-grade students from Junior High School X Yogyakarta. The experimental group used discovery learning-based e-worksheets, while the control group used conventional printed worksheets. Data was collected using a critical thinking test with 10 questions covering five indicators. Results showed significant improvements in the experimental group (N-gain = 0.23), while the control group declined (N-gain = -0.18). The experimental group's mean score increased from 42 to 56, whereas the control group declined from 41 to 37. The highest improvement was in the "providing arguments or explanations" indicator (N-gain = 0.425). The Mann-Whitney test indicated significant differences between groups (p < 0.05), with the experimental group achieving a higher mean rank (39.45) than the control group (21.55). These findings suggest that integrating digital tools in discovery learning effectively enhances students' critical thinking skills in science education.
