Using Augmented Reality Technology to Learn Cube Expansion Diagram in Spatial Geometry of Elementary Mathematics

Spatial geometry has always been the key and difficult part in the curriculum of elementary mathematics. Compared with traditional teaching methods using, Augmented Reality (AR) technology shows its potential to teach spatial geometry through visualization, interaction and situation. This study focused on cube expansion diagram in spatial geometry and developed an AR learning tool based on inquiry for the course. The research aimed to examine the effectiveness of AR-assisted math lesson by designing and implementing two lessons in an elementary school. Two classes including 92 students in grade 5 participated in this study, and they were assigned to an experimental and a control group. This study adopted mixed methods methodology and utilized pre/post-tests, questionnaires and interviews. Results showed that students can general accept of using AR to learn spatial geometry, and AR-assisted teaching methods significantly improved students' learning outcome. It is also noticed that students' learning level affected their performance in AR-assisted math lessons.
