<![CDATA[IPAS learning in elementary schools is still dominated by memorization methods and teacher-centered approaches, particularly in the topic of Indonesia’s Cultural Wealth, which contains broad and complex material. The lack of innovative learning media leads to passive students and less engaging learning experiences. This study aims to develop, evaluate the feasibility, and examine the effectiveness of a Project-Based Learning (PjBL)-based E-LKPD on the topic of Indonesia’s Cultural Wealth for fourth-grade elementary school students. The development followed the ADDIE model and employed interviews, observations, questionnaires, and objective tests. Data were analyzed using qualitative descriptive, quantitative descriptive, and t-test techniques. The subjects involved in this study included one instructional design expert, one content expert, one instructional media expert, one media expert, three students for individual trials, nine students for small group trials, and 30 fourth-grade students for the effectiveness test. The results showed that the E-LKPD was feasible based on expert validation, receiving excellent ratings from the content expert (93.18%), design expert (85%), media expert (90%), and also from individual (90%) and small group trials (91.38%). The E-LKPD was also found to be effective as indicated by the t-test result, where t-value (20.239) > t-table (2.045). Therefore, it can be concluded that the PjBL-based E-LKPD is both feasible and effective for use in IPAS learning, particularly in the topic of Indonesia’s Cultural Wealth. The implication of this research suggests that the E-LKPD is valid, feasible, and effective for improving learning outcomes, motivation, and student engagement in IPAS learning for fourth-grade elementary school students.]]>
