Learning Objects for Education with Augmented Reality

To fill the gap of next-generation user interfaces for mathematics and geometry educationConstruct3D is presented, a three-dimensional dynamic geometry construction tool that can be used inhigh school and university education. This system uses Augmented Reality (AR) to provide a naturalsetting for face-to-face collaboration of teachers and students. The main advantage of using AR is thatstudents actually see three dimensional objects which they until now had to calculate and constructwith traditional (mostly pen and paper) methods (Figure 1). By working directly in 3D space, complexspatial problems and spatial relationships may be comprehended better and faster than with traditionalmethods. This paper summarizes the development of learning objects and content specificallydesigned for teaching dynamic 3D geometry in Augmented Reality. It concentrates on pedagogicalfindings while working with teachers and students in more than 500 teaching lessons.
