Abstract
We developed an Authentic GeometryGo (AGG) app to help students application of geometry in authentic contexts through authentic measurements and peer assessments. The study included an experimental group (EG) using an AGG app and a control group (CG) using paper-based methods. The results showed that the EG outperformed the CG in terms of estimation. Measuring authentic geometry shapes using the app could foster students’ estimation. Furthermore, meaningful peer assessments with visual representations in authentic contexts can facilitate the evaluation of peers’ work and improve students’ geometry understanding. Therefore, we encourage educators to use augmented reality with appropriate learning activities to sharpen students’ measurement quality and visual representations by measuring real geometry shapes and applying mathematics knowledge in authentic contexts.
