Development of Augmented Reality (AR) Based Learning Media for Geometry

Abstract

Students’ limited understanding of surface area and volume in three-dimensional geometry is influenced by insufficient instructional time and a lack of innovative learning media. This development research aims to produce an augmented reality (AR)–based learning application that is valid and practical for geometry instruction. The study employed the ADDIE development model, which consists of Analysis, Design, Development, Implementation, and Evaluation stages. During the implementation phase, peer teaching was conducted involving 17 graduate students from the Mathematics Education Department at Universitas Negeri Malang. The results indicate that the AR learning application was successfully developed for three-dimensional geometry topics. Data analysis shows that the average validity score of the developed media was 3.35, while the average practicality score was 3.87. These findings suggest that the AR-based learning media are valid and practical for supporting students’ understanding of surface area, volume, and geometric elements.
