This study aims to develop an SSI-based electronic learning material [e-LM] that will respond to the current educational landscape. Socio-scientific issues are utilized in the e-LM recognizing it can be useful in resolving societal issues and assisting learners in developing scientific habits of mind. A Mixed-method research design was employed in the development and validation of an SSI-based e-LM. Brain DeCor eLM Framework, an SSI-based e-LM design framework highlighting lifelong learning, ethical, and sustainability issues in situations became the basis of SSI-based e-LM development. Its salient features such as the priority SSIs, e-LM design structure, appropriate teaching strategies, and suitable teaching approaches became the basis for its development. It was validated by five science facilitators considering the salient features and found out, they were highly incorporated. The study recommends its implementation on the intended participants. Furthermore, implementing the developed e-LM was also suggested to be validated considering the e-collaborative activity assessment and the result of student participant's reflection time assessment. The student performance in science achievement will denote the effectiveness of the developed e-LM.
