This research focused on the development and evaluation of a Radio-Based Instruction (RBI) learning material for Araling Panlipunan, specifically for Grade 6 students at San Fernando Integrated School. Utilizing a quantitative-developmental design based on the ADDIE model to create the RBI learning material, the resource was developed based on the least mastered competencies as identified through the First Quarter Examination in addition to topics related to the Philippine Revolution such as Sigaw sa Pugad Lawin, Tejeros Convention and Kasunduan sa Biak-na-Bato. An evaluation tool was created by adapting the DepEd LRMDS guidelines and data analysis was completed utilizing mean and t-tests. Overall, results indicated a very satisfactory rating (Mean = 3.76) which indicates that the RBI resource meets instructional and technical requirements. In addition to high ratings being obtained across all domains, scriptwriting conventions (mean = 3.80) and intellectual property rights (mean = 3.79) received the highest ratings, however, technical design (mean = 3.69) received the lowest rating; although it also received a very satisfactory rating. Additionally, a statistically significant difference was observed in the domain of intellectual property rights (t = 2.973, p = 0.008) in which Master Teachers provided higher ratings to the RBI resource compared to grade 6 teachers. However, statistically significant differences were not observed in any other domain (P > .05). The results indicate that RBI is a viable and curriculum-based instructional alternative in contexts where access to technology is limited.
