Abstract
E-books are an alternative teaching material that can be used by teachers and students anytime and anywhere. Chemistry is one of the sciences that has an abstract concept. By integrating the STEM approach (science, technology, engineering, and mathematics) into the e-book, it is hoped that it will enable students to have critical thinking skills, so that they are able to provide creative solutions, and be able to compete in the world of work. This study aims to develop a chemistry e-book for class XI semester 1 integrated with the STEM approach. The type of research conducted is research & development (R&D) with the ADDIE development model. This research is limited only to test the validity only. The instruments used were material and media validity sheets. Based on the results of the validity questionnaire analysis conducted by 4 validators, it was obtained 3.67 for material validity and 3.75 for media validity from the largest scale, namely 4. The data results revealed that the e-book that had been developed was valid in terms of material and media validity so that able to become one of the ebooks that can be tested for development.
