augmented reality, teacher training, mathematics teachers, digital technologies

The chapter is devoted to the application of augmented reality (AR) in teacher-training programmes at universities. The first part describes the opportunities of future mathematics teachers at the Faculty of Mathematics, Physics and Informatics of Comenius University in Bratislava to work with digital technologies. The second, main part, describes the research of the AR application: Augmented Polyhedrons – Mirage 2.2. We conducted two studies with 40 future teachers. Results support the suitability of the selected application and AR in general. However, the implementation has to be precise, with carefully chosen and formulated tasks to solve. The last part of the chapter summarizes useful AR applications for secondary schools.
