The role of technology in education, particularly in language learning, for which the Duolingo app is very popular. As a gamification-based learning app, Duolingo offers the potential to address these challenges through an innovative and interactive approach. However, there is a gap in research regarding its impact on younger students in primary education. This research addresses the gap by examining what motivates younger students to use Duolingo and how it affects their learning experiences. This study used a descriptive qualitative approach with data collected through questionnaires and observations of 24 students of class VI E at SD Islam Al Azhar 25 Semarang. To ensure the validity of the data, this study used researcher triangulation through the meta-observation method. Questionnaires focused on identifying students’ intrinsic and extrinsic motivation factors, while observations recorded students’ responses during the learning process using the app. The results showed that students' intrinsic motivation, such as enjoyment and interest in learning, increased when using Duolingo. In addition, extrinsic motivation, such as rewards from the gamification feature, also encouraged students to study harder. Most students reported that Duolingo helped improve their vocabulary and grammar acquisition, although some students faced obstacles in pronunciation and complex grammar features. This study implies that Duolingo can be a supporting tool in primary schools' English language learning.
