THE EFFICACY OF INTERACTIVE APPLICATION BASED MEDIA IN ENHANCING SPATIAL GEOMETRY: A STUDY AT ONE OF THE ELEMENTARY SCHOOL IN BANDUNG

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 DesignBased 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
