<![CDATA[Science and Social Studies Learning (IPAS) in elementary schools continues to face challenges in fostering students' creativity, motivation, conceptual understanding, and active participation in learning. This study aims to evaluate the effectiveness of implementing Project-Based Learning (PjBL) supported by diorama media in enhancing students' competencies and learning outcomes. The study employed a Systematic Literature Review (SLR) method guided by the PRISMA framework, focusing on scientific articles published between 2021 and 2025. The articles were identified through keyword searches in Google Scholar and selected based on relevance and quality criteria, resulting in ten articles that were systematically analyzed. The findings indicate that the implementation of PjBL assisted by diorama media consistently contributes to the development of students' creativity, learning motivation, conceptual understanding, reasoning skills, and classroom engagement. These findings suggest that the integration of PjBL with diorama media positively contributes to the effectiveness of IPAS instruction in elementary schools. Future studies are recommended to expand the scope of investigation across different grade levels and IPAS topics to strengthen the evidence regarding the effectiveness of PjBL supported by diorama media. Practically, these findings imply that educators may utilize PjBL assisted by diorama media as an instructional strategy to improve the quality of learning.]]>
