This study involved the development steps of the ADDIE model including analysis, design, development, implementation, and evaluation. A likert scale with four variations of answers was used in this study. The data were analyzed by quantitative descriptive and inter-rater reliability. The results showed that the developed product-based e-module have fulfilled good criteria of materials, media and feasibility from the users. The results revealed that: (1) the e-module was considered very good by the material experts in the aspects of self instructional, self contained, stand alone, adaptive and user friendly with the feasibility percentage of 94.16%. Furthermore, the media experts also assessed the e-module as good with the feasibility percentage of 80% in the ascpects of verbal, visual, programming and module component; (2) the users¡¯ response was very good with the feasibility percentage of 85.39%. The accuracy level was also good based on the teachers¡¯ evaluation with a mean score of 0.729. http://pubs.sciepub.com/education/9/4/9/education-9-4-9.pdf e-module product based learning media
