This study aims to develop and evaluate concept map-based Science Student Worksheets (LKS) to improve learning outcomes of fourth-grade students at SDN XXX. Using a quasi-experimental nonequivalent control group design, two groups were involved: an experimental group using concept map-based LKS and a control group using conventional LKS. The sample consisted of 31 students selected through random sampling. Data were collected through pretests, posttests, expert validations, and student and teacher responses, then analyzed using descriptive statistics, N-Gain, and t-tests. Results showed that the experimental group achieved a higher posttest mean score (85.71) compared to the control group (70.71), with an N-Gain of 0.68 (moderate-high) versus 0.36 (low). Expert validation indicated high validity and practicality (average score 92.5%). Students reported improved conceptual understanding and engagement due to the visual and systematic nature of concept maps. Statistical analysis confirmed a significant positive effect (p < 0.05) of the concept map-based LKS on learning outcomes. This study concludes that concept map-based LKS are effective learning tools for enhancing science conceptual mastery and recommends their broader application and integration with interactive media.Referensi
