English learning media in elementary schools plays an important role in supporting the English language teaching process for young learners. This research aimed to develop augmented reality-based flashcards for vocabulary learning for fifth-grade students at SDN 010 Tarakan. This was a research and development study using the 4D model, consisting of the Define, Design, Develop, and Disseminate stages. The research instruments used included student needs questionnaires, interview guides for teachers, expert validation questionnaires for content and media, media usability questionnaires, and student response questionnaires. The results of the needs analysis questionnaire and interviews with teachers indicated that vocabulary learning media were highly needed by students in their English language learning. The designed product consisted of flashcards featuring vocabulary related to parts of the body, hobbies, and things in school, in accordance with the students' needs. The developed media were then validated in terms of content and media before being pilot-tested on 12 fifth-grade students at SDN 010 Tarakan. The research results revealed that the level of suitability and practicality of the media, based on the following assessments, were as follows: 1) validation by a media expert yielded a score of 93.7%, classified as “highly applicable”; 2) validation by a content expert yielded a score of 96.3%, classified as “highly applicable”; 3) 97.1% of English language teaching practitioners rated the material as “highly practical.” Student responses to this learning material following the pilot test were positive, with a score of 91% of the total possible score. Accordingly, it can be concluded that the development of augmented reality-based flashcard learning materials for fifth-grade students at SDN 010 Tarakan was deemed highly feasible and highly practical for use.
