The population and sample of this study were 10th-grade students at SMAN 1 Deli Tua, and the sample consisted of 10th-grade students in the MIA 3 class at SMAN 1 Deli Tua. Based on the data analysis, the results of expert validation yielded a material expert validation score of 88.16% with a category of very feasible, and a media expert validation score of 90.7% with a category of very feasible. The results of the practicality test on a small scale showed that the ease aspect obtained a percentage of 91.3%, the attractiveness aspect obtained a percentage of 91.8%, and the usefulness aspect obtained a percentage of 90.2%. The results of the large-scale trial showed that the e-module obtained a highly practical category, reaching 92.6%. The ease aspect obtained a percentage of 93.2%, the attractiveness aspect obtained a percentage of 94%, and the usefulness aspect obtained a percentage of 90%. Both small and large-scale tests yielded a highly practical category. The effectiveness test showed that the average pre-test score obtained by students was 37.66, and the average post-test score was 89.6%. Based on the N-gain test, it was found that the average N-gain score of students was 0.84 or 83.94%, which is interpreted as having high effectiveness. Therefore, the product developed in this study is considered feasible, practical, and effective in supporting students' self-directed learning process on the topic of work and energy and can improve students' learning outcomes
