Natural and Social Sciences (IPAS) learning in elementary schools plays a crucial role in helping students understand natural and social phenomena in an integrated manner. However, the implementation of IPAS learning still tends to be textual and textbook-centered, with limited connections to students’ real-life experiences, thereby failing to support deep learning fully. This study aims to analyze the forms of contextualization of IPAS materials, examine their implications for deep learning, and identify obstacles to their implementation in elementary schools. The research employed a Systematic Literature Review (SLR) method using the PRISMA approach to analyze articles published between 2021 and 2025. A total of 1,301 articles were initially identified from the Google Scholar, Scopus, and Crossref databases using the Publish or Perish application, of which 14 relevant articles were selected based on predetermined inclusion and exclusion criteria. The findings indicate that the contextualization of IPAS materials is implemented through several approaches, including the use of visual and interactive media, environment-based and experiential learning, problem-based and inquiry-based approaches, the integration of local potential, interdisciplinary learning, and multimodal representation. These approaches contribute to improving students’ motivation to learn, conceptual understanding, critical thinking skills, learning autonomy, and metacognitive awareness, which are key indicators of deep learning. However, challenges remain, particularly related to limited teacher pedagogical competence, insufficient contextual learning media, and structural constraints within the education system. Therefore, strengthening teacher competence, developing contextual learning designs, and enhancing institutional support are essential to promote meaningful and sustainable IPAS learning in elementary education.
