Development Of Guided Discovery Based Electronic Module For Chemical Lessons In Redox Reaction Materials

This research is the development of guided discovery based electronic module that aims to know the eligibility level of e-modules and student responses to guided discovery-based electronic modules in redox reaction material. This electronic module uses the ADDIE development model. The research was conducted at one of the high schools in Bengkulu with the subject 9 students of X MIPA A Students for small scale trials and 30 students of X MIPA D Students for large scale trials. From the results of the research obtained (1) the percentage of the feasibility of e-modules on the material aspect is 86,315% while from the media aspect is 91.425% so that based on the results of validation by the E-module validator is declared very valid, (2) based on the test results of the small-scale student response percentage of 75.97 % with interesting category, while for large-scale trials of 84.48% with a very interesting category. From the results percentage, it can be concluded that e-module is suitable for use in learning. Electronic module based on guided discovery is an effective tool to help students in learning redox reaction subject. E-module can be accessed by smartphone or laptop. With this e-module, students can access the study material from everywhere without any time limitation.
