AR-GeoShapes: Development and Evaluation of a Marker Less Augmented Reality Based Geometrical Shapes Learning Framework on Memory Retention and Learning Achievement

A large number of students struggle to grasp geometric principles, especially in three-dimensional (3D) space. In turn, this is why digital educational tools have been integrated more and more into the learning environment: because they entertain students. One of these technologies is Augmented Reality (AR) which has become a widely researched and effective tool for education. Where learning is situated with content embedded within the physical environment (support), AR better enables offerings to be adapted. This paper presents AR-GeoShapes, an augmented reality-based educational tool developed to help students learn solid geometry concepts. Built with the Vuforia marker less SDK in Unity, AR-GeoShapes is an exercise that runs on mobile devices for users to learn shapes interactively. Further to evaluate whether using AR-GeoShapes helps increase memory retention and improve learning achievement, a comparative study involving 58 students was conducted. The results demonstrate that the experimental group, utilizing AR-GeoShapes, exhibited significantly higher memory retention and learning outcomes compared to the control group. These findings suggest that AR-GeoShapes are a valuable tool for enhancing students' comprehension of geometric concepts.
