Instructional media have yet to be applied innovatively and variedly in the delivery of Indonesian language material so that it impacts the learning outcomes of fifth-grade elementary school students. This study analyzes interactive learning media's development process, validity, and effectiveness on learning outcomes in Indonesian subjects. This research is included in research development (Research & Development). The test subjects in this study were one material expert, one media expert, one design expert, and 24 fifth-grade elementary school students. Data collection methods used are questionnaires and tests. This study used three data analysis techniques: qualitative descriptive analysis, quantitative descriptive analysis, and inferential statistical techniques (t-test). The results of this study indicate that the validity results obtained by material experts are 96.36% (very good), design experts are 95% (very good), media experts are 94.66% (very good), and responses from students are confident in individual trials 85 .08% (good), small group trials 83.47% (good), and field trials 80.20% (good). Based on the pre-test results of 61.67 percent (poor) and the post-test results of 85.25 percent (good). The results show that the significance level is less than 0.05. (p˃0.05). Based on the results of this analysis, it can be concluded that interactive learning media is valid and effective in improving the learning outcomes of fifth-grade elementary school students.
