The University of Education Schwäbisch Gmünd is a small, but fully accredited public University near Stuttgart, Germany, with a strong focus on teacher education. It is tightly embedded into the network of six Universities of Education in the state of Baden-Württemberg. The project coordinator, Prof. Dr. Ulrich Kortenkamp has been appointed by the University in April 2006 as a professor of computer science and media education, and he is the head of the Department of Computer Science since then. Before that, Prof. Kortenkamp was a professor of mathematics education at the Technical University of Berlin, and a funding member and scientist in charge (application area Education) of the DFG-funded Research Center "MATHEON – Mathematics for Key Technologies'', where he is still a project leader. The MATHEON is one of only six Research Centers in Germany, and is funded with more than 5 million Euros each year by the DFG (German Research Foundation). It has been established in 2002 and was successfully reviewed in early 2006.

Professor Kortenkamp works in the field of interactive Geometry and web-based teaching since 1996, when he started work on the interactive Geometry software Cinderella. His Ph.D. thesis on the Foundations of Dynamics Geometry was concluded at the Swiss Federal Institute of Technology Zurich and was awarded with the ETH Medal for outstanding Ph.D. theses. The software has won many awards, among them the European Academic Software Award 2000 and the German Educational Software Award digita2001. It is commercially available worldwide in several languages through Springer-Verlag, Heidelberg. The latest version, Cinderella.2, has been released in June 2006, and has since been adopted by some major academic institutions as well as schools. A main research topic of Prof. Kortenkamp is the interaction between computer algebra software and interactive geometry software, as well as standards for data exchange between mathematical software. He has been an invited speaker on this and other topics at national and international conferences. Together with Arjeh Cohen, TU Eindhoven, there has been prior work on one of the central topics of this proposal, the OPENMATH-encoding of geometric constructions.
