As a facilitator in the learning process, teachers are expected to be able to create an atmosphere of the teaching and learning process by providing various alternative media and learning resources for students. Along with the development of science and technology in the 4.0 revolution era, the use of electronic modules (e-modules) is one option that teachers can choose. This study aims to develop a valid and feasible e-module of trigonometry based on the flipped classroom model. This type of research is Research and Development by applying a 4D model. This study involved students of class XI MIPA 4 at SMAN 1 Gorontalo. The instruments used are validation sheets and student response questionnaires. The results of the validity of the e-module by material and media experts are 86.45%. This shows that the developed e-module has met the feasibility aspects of content, language, components of presentation consistency and content design. The results of the calculation of the student response questionnaire show that the developed e-module meets the eligibility criteria with a percentage of 85%. It can be concluded that the trigonometry e-module based on the flipped classroom learning model is valid and feasible. © 2025 American Institute of Physics Inc.. All rights reserved.
