Research Trends in Outdoor Learning in Science Education: A PRISMA-Based Systematic Literature Review (2021–2025)

This study aims to examine research trends and synthesize key findings related to the implementation of outdoor learning in science education through a Systematic Literature Review (SLR) approach. The literature search was conducted using the Scopus database and focused on publications published between 2021 and 2025. The initial search retrieved 197 records, which were subsequently screened in accordance with the PRISMA guidelines using predefined inclusion and exclusion criteria, resulting in 12 studies being selected for further analysis. Based on the descriptive mapping and synthesis of the selected studies, the findings suggest that outdoor learning may enhance students' conceptual understanding, engagement, learning motivation, and several aspects of thinking skills, although direct evidence regarding critical thinking remains limited. The reviewed studies suggest that outdoor learning may support conceptual understanding, engagement, motivation, and some aspects of thinking skills, although direct evidence on critical thinking remains relatively limited. Mixed methods emerged as the most frequently used research approach, followed by qualitative and quantitative methods. The review further identifies underexplored areas, particularly technology integration and the implementation of outdoor learning across diverse educational contexts, highlighting important opportunities for future research.
