<![CDATA[This study addresses the growing issue of food loss and food waste as a relevant socio-environmental problem in education, particularly in fostering students’ scientific literacy at the elementary level. The urgency of this research lies in the need to integrate real-world sustainability issues into science learning to support students in developing critical and reflective thinking skills, as well as to contribute to the achievement of Sustainable Development Goals related to hunger, responsible consumption, and climate action. The objective of this study is to develop a Socio-Scientific Issue-based supplementary learning module on food loss and food waste that is valid, practical, and effective for elementary school students. This research employed a Research and Development approach using the Borg and Gall model, involving four elementary schools in Bandung City, with one school for a limited trial and four schools for field testing, consisting of three private and one public school. The results indicate that the developed module meets theoretical and empirical validity criteria and is feasible for use. Responses from experts, practitioners, and students show that the module is highly practical. Furthermore, post-test results demonstrate a significant improvement in students’ scientific literacy, indicating that the module is effective. In conclusion, the Socio-Scientific Issue-based module on food loss and food waste is a valid, practical, and effective learning resource to enhance elementary students’ scientific literacy.]]>
