Using the Intergeo platform for teaching and research

We describe the key achievements of Intergeo, a project co-funded within the eContentplus programme of the European Union, and their impact on teacher education, based on the technical and educational concepts of the Intergeo Platform. THE INTERGEO PROJECT The Intergeo project started in October 2007 and will be funded until September 2010. Its main concern is the propagation of Interactive or Dynamic Geometry Software throughout Europe. Interactive Geometry is a way to improve mathematics education by using computers and Dynamic Geometry Software (DGS) and there are many advantages in comparison to “classical ” geometry without DGS [Kortenkamp et al. 2009]. Figures can e.g. be easily manipulated [see e.g. Roth 2008] and thus virtually be brought to life. The Intergeo Project tries to break three major barriers that have a negative impact on the use of Interactive Geometry in classrooms [Intergeo Consortium 2008]: Missing search facilities for existing resources, lack of interoperability caused by the various amount of different programmes and file formats for Interactive Geometry, an
