English is one of the essential subjects in the curriculum However, the outcomes of the English learning at the National level have not met the desired level of achievement. This study examines how interactive multimedia, namely Articulate Storyline 3, is used in English lessons for junior high school students. Moreover, it aims to determine a) whether Android-based interactive multimedia effectively improves students' English learning outcomes, b) explain how Android­based interactive multimedia can increase students' motivation in their English learning, and c) how students perceive the implementation of Android-based interactive multimedia in English learning. This study is part of quantitative research that employs experimental research methods. A quasi-experimental design shows how Android-based interactive multimedia for English subjects can improve student learning outcomes and motivation. The researcher used documentation and observation checklist, tests, and questionnaires as instruments research gathered to measure the aims of the study. As it was a quasi-experiment, the sample used was 66 students, including 33 students in the control class and 33 students in the experimental class. The findings revealed that a) implementing Android-based interactive multimedia in English learning effectively improves students' English learning outcomes. The improvement in students' English learning outcomes is proven by the difference in learning outcomes of students in the experimental class who used Android-based interactive multimedia, which had higher learning outcomes compared to those in the control class who did not use Android-based interactive multimedia in learning. b) Android-based interactive multimedia increases students' motivation for English learning. It is proven that in the learning process, students feel that teaching attracts more students' attention and fosters learning motivation in learning English. c) Android-based interactive multimedia is appropriate for learning English. Student surveys show that Android-based interactive multimedia, especially Articulate Storyline 3, facilitates students' learning of English, motivates them to learn, increases their learning outcomes, and makes them study independently. In conclusion, implementing Android-based interactive multimedia is worth doing in English learning, especially in junior high school.
