The results showed that from the E-module feasibility test, the lecturers were subject matter experts, language expert lecturers, media/design expert lecturers, and one teacher. Based on the validation of material experts, it is obtained an average total score of 97% or classified as very valid. Then, the next validation shows valid criteria with an average score of 100% linguists. Design validation obtained a total average score of 95%, 94%, and an average score of 80%. One teacher tested the practicality of the E-module with a score of 98%. The student response test conducted on 13 grade IV students obtained a value with a proportion of 97%. E-modules in Discovery Learning-based thematic learning include features that are very practical or very feasible to use.
