This study sought to develop an electronic student worksheet (E-LKPD) based on Liveworksheet for fourth-grade science and social science (IPAS) learning on the topic of Norms in Local Customs and to evaluate its validity, practicality, and effectiveness. The research adopted a Research and Development (R&D) method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation. The participants were 17 fourth-grade students of SD Negeri Gampong Teungoh. Data were collected through observation, interviews, expert validation sheets, teacher and student response questionnaires, and pretest and posttest. Data were analyzed descriptively using percentages and N-Gain analysis. The results showed that the E-LKPD obtained validation scores of 93.33% from the content expert, 92% from the media expert, and 87.5% from the language expert, indicating a very feasible category. Teacher and student responses indicated that the product was highly practical, while the N-Gain score of 0.67 indicated a moderate improvement in learning outcomes. Therefore, the developed Liveworksheet-based E-LKPD is valid, practical, and effective for fourth-grade IPAS learning.]]>
