Abstract

Mathematics instruction regarding spatial geometry in elementary education frequently encounters pedagogical hurdles due to the abstract nature of the concepts, the inadequacy of conventional instructional tools, and suboptimal student engagement. This study aims to develop and evaluate the effectiveness of an interactive, application-based learning tool designed to bridge the gap between abstract geometric concepts and student comprehension. Adopting a Design-Based Research (DBR) framework, the study focused on the iterative development of an interactive media product. The research subjects were 29 fifth-grade students at one of the elementary school in Bandung. Data were triangulated through pre-test and post-test assessments, systematic observation of student activities, and user experience (UX) questionnaires. The media was constructed using Smart Apps Creator and Canva for high-fidelity visual design. The findings demonstrate that the developed media significantly improved student learning outcomes, with an N-gain score falling within the ^Moderate^ effectiveness category. Furthermore, the media elicited high positive responses regarding student motivation, aesthetic visual design, and interface usability. Reflective analysis suggests that while effective, future iterations should prioritize enhanced audio synchronization, intuitive navigation, and more robust interactive features to maximize pedagogical impact. Overall, this application-based medium serves as a practical and effective alternative for teaching spatial geometry in primary education.
