In the field of education, the presence of technology has helped teachers a lot in carrying out learning. Future education cannot only focus on cognitive aspects. To face various problems and challenges of the times in the future, students are expected to have much better attitudes, skills, and knowledge competencies, to be more creative, innovative, and productive. The purpose of this research is to analyze the feasibility and effectiveness of the development e-module Biology based on Contextual Teaching and Learning (CTL) on the material structure and function of plant and animal tissues to improve the critical thinking skills of students in class XI MIPA SMA that are valid, practical, and effective. The results showed that the e-module Biology based on Contextual Teaching and Learning (CTL) on the structure and function of plant and animal tissues to improve critical thinking skills of students in class XI MIPA SMA has a very valid category with a validator value of 89.33%, very practical 93.33% by Biology teachers and students with a score of 87.52% and the results of the effectiveness test of the CTL - based e-module showed that it was very effective, there was a significant difference between classes that used CTL - based e-modules and classes that did not use CTL - based e-modules . So, it can be concluded that the CTL-based Biology e-module that has been developed is very valid, very practical, and very effective.
