JelajahOptik: Bridging Gaps in Rural Science Learning with Affordable Innovation

This paper presents the development and usability analysis of the “JelajahOptik” model, a low-cost and practical teaching aid designed for lower secondary Science in rural schools. The model was developed based on the ADDIE instructional design framework to address educational gaps caused by limited laboratory access and technological constraints in rural schools in Malaysia. The study involved 108 lower secondary students from Kuala Krai, Kelantan, and assessed usability in terms of usefulness and satisfaction. Findings indicated high validity, CVI (face validity = 0.80, content validity = 0.93) and reliability of survey with Cronbach’s Alpha value of 0.86. Descriptive analysis using SPSS revealed high mean scores for usability constructs, usefulness (M=3.81, SD=0.20) and satisfaction (M=3.80, SD=0.25). The “JelajahOptik” model demonstrates strong potential for national-scale implementation and commercialization as a cost-effective, eco-friendly, and inclusive science education tool.
