GemAR: Geometry Augmented Reality Application for Elementary School Students

Much research on AR developed to support the learning process. One of them is for learning mathematics in the field of geometry for elementary school students. However, some of the developed applications based on a marker. So, It is very dependent on the availability of print markers in operating them. This research develops markerless-based Geometry Augmented Reality (GemAR) to help a 6th-grade elementary school student learning about Geometry. GemAR application has eight 3D Geometry objects that can display. There were 60 students (28 students in the experimental group and 32 students in the control group) and two class teachers involved in this study. The experimental group used the GemAR application during the teaching and learning process, while the control group used a whiteboard and slides displayed via the Projector LCD. The result is the experimental group experienced an increase in learning outcomes based on the pre-test and post-test results in both groups. GemAR application testing results with an experimental group and two class teachers, 75% agreed that the GemAR application helped students understand the content taught, and 85.71% agreed that the GemAR application was proper to use in the learning process.
