The modules were developed based on the needs of teachers and students obtained through observation, interviews, and diagnostic tests on students. Data analysis techniques using qualitative and quantitative descriptive analysis. The study's results, namely the validation of the experts on the module, showed a very good category for the material, display, and graphic aspects. The developed module is considered very practical for teachers in the classroom, while the student response to learning using the module is very good. It has a direct impact on student learning outcomes which are very satisfying. Thus, the developed module is feasible and can be an alternative reference for teachers in carrying out STEM-based learning by integrating the values of the Pancasila Student Profile.
