<![CDATA[Students' learning outcomes on the human digestive system subtopic remain suboptimal, indicating the need for learning resources that actively engage students in the learning process. This study aimed to analyze the effectiveness of a Discovery Learning-based Electronic Student Worksheet in improving students' learning outcomes on the human digestive system subtopic. The study employed a quantitative approach using a One-Group Pretest–Posttest Design involving 30 eleventh-grade students of MAN 1 Jombang. Data were collected through a learning implementation observation sheet and pre-test and post-test instruments. The data were analyzed using percentage analysis, the Paired Sample t-test, and the Normalized Gain (N-Gain) score. The results showed that the learning implementation reached 97.6%, which was categorized as very good. The average student score increased from 42.2 in the pre-test to 88.3 in the post-test. The Paired Sample t-test indicated a significant difference between the pre-test and post-test scores (p < 0.05), while the average N-Gain score was 0.78, which falls into the high category. These findings indicate that the Discovery Learning-based E-LKPD is effective in improving students' learning outcomes on the human digestive system subtopic.]]>
