Abstract: This research investigates San Vicente, Sta. Irene, and Poblacion barangays ecological profiles in Prosperidad, Agusan del Sur, as a basis for creating localized Araling Panlipunan teaching materials. In the hope that documents are not easily accessible in most rural municipalities, the research tried to document history and make it more relevant in the classroom. With a historical-descriptive research design, data were collected through key informant interviews with elderly residents of the community and retired barangay officials, municipal records, and ecological data from the Community-Based Monitoring System (CBMS). The research was aimed at describing the barangays in terms of their history, geophysical and demographic characteristics, and economic progress. These information were used to come up with contextualized instructional modules, validated by master teachers in the subject, and disseminated to schools for incorporation in the Social Studies curriculum. The research emphasizes the richness of locality narratives and the importance of place-based learning in deepening students understanding of identity, community, and sustainability. Through academic knowledge embedded in everyday experience, the research illustrated enhanced learning and appreciation of local culture among students.
