Learning spatial geometry is still abstract, thereby it is boring and less meaningful. As a result, learning outcomes in terms of skills and cognitive aspects become less optimal. Currently, students no longer rely on textbooks as a learning resource. E-modules are digitally designed learning resources that support independent learning. The e-module would be integrated with the STEM approach. STEM learning activities are very important and need to be familiarized with learning because the activities help prospective teachers build the concepts learned as well as practice solving complex real-world problems. The method was research and development using the ADDIE model. The research subjects were 78 2nd semester students of prospective mathematics teachers in the Mathematics Education Study Program, Universitas Tidar. Data were collected by using observation sheets, interview guides, questionnaires, and complex problem-solving tests. There are three main results from the study; first, the STEM-based spatial geometry E-module is declared to be strongly valid according to expert validators. Second, based on student responses, this e-module is practical, and third, based on the results of the complex problem-solving skills test, this STEM-based spatial geometry e-module is effective. © 2024, Qubahan.
