<p align="center"><em>The Covid 19 pandemic and rapid technological developments require all mobile-based educational activities, while most of the teaching materials available are still printed teaching materials. In addition, the existing printed teaching materials have not provided opportunities for students to build their own knowledge. This study aims to produce an electronic chemistry module with a constructivism approach for SMA / MA students. This research is a research development (Research & Development) with a 4-D development model, namely, define, design, develop, and disseminate. The technique of collecting data through a response questionnaire uses a validation sheet. The results showed that the quality of the content and objectives of the module was 88.33%, the construction quality was 93.33% and the technical quality was 98.96%. Overall, the quality of the modules produced is 93.11%, so it can be concluded that the electronic module with the resulting constructivism approach is very valid.</em></p>
