<p>This study is aimed for developing an electronic module (e-module) on the material of circulation system based on learning cycle 8e. This type of research and development used the Analysis, Design, Development, Implementation and Evaluation (ADDIE) model. The used research instruments were interview sheets and validation questionnaires. The e-module was validated by three experts and the validated aspects were included aspects of didactic, construction and technical. The obtained data were analyzed quantitatively and described descriptively. The results of the study found that the didactic aspect obtained the highest validity value of 96.15% in the II learning material. While the construction aspect found the highest validity value in learning material III was 95.63%. In the technical aspect, the highest score was obtained in learning material III of 93.75%. Therefore, it can be concluded that the e-module circulation system based on learning cycle 8e has good quality and can be used in learning activities.</p>
