This study aims to determine the science learning outcomes of grade III of Jaya Mulya State Elementary School after the implementation of Discovery Learning-based LKPD. The type of research used in this study is experimental research. A quasi-experimental study does not use a comparison class. The study used a pre-experimental design. In this study, the experimental form used was a one-group pre-test-post-test design. The population in this study was all grade III students of Jaya Mulya State Elementary School in the 2025/2026 academic year, totaling 24 students. The data collection technique used a test technique with 20 questions. The data analysis technique used the Z-test, resulting in a calculated Z-value of 3.50, while the Z-table at a significance level of 0.05 (one-sided) was 1.65. Because the calculated Z-value is greater than the Z-table (3.50 > 1.65), the decision is to reject H₀ and accept Hₐ. Based on the results of the data analysis, the average pre-test score was 63.04 and the average post-test score was 77.04, indicating an increase in student learning outcomes of approximately 14.00 after the implementation of Discovery Learning-based Student Worksheets (LKPD). The implementation of Discovery Learning-based Student Worksheets (LKPD) can improve student learning outcomes. Students who complete learning or obtain a score of ≥ 70. This indicates that the implementation of Discovery Learning-based Student Worksheets (LKPD) can improve student learning outcomes.
