This study developed and evaluated a supplemental learning module in Science, Technology, and Society (STS) for college students at the City College of Angeles during AY 2025–2026. Guided by the ADDIE model, the study identified least-learned competencies, particularly Nation Building and Technology as a Way of Revealing, which involved understanding the role of science, policy, local innovation, and indigenous knowledge in socioeconomic development, as well as Heidegger’s philosophical perspectives on technology. Based on these learning gaps, a supplemental module was developed and evaluated by five experts, who rated it highly valid for classroom use. Students also found the module understandable and acceptable. Pretest and posttest results showed significant improvement in learning performance, suggesting that the module contributed positively to students’ understanding of difficult STS competencies. The study recommends its use as a supplementary instructional resource by STS instructors to reinforce learning and promote critical thinking and the practical application of concepts.
