I am concerned with dynamic geometry for many years now. During my time as a teacherfor mathematics and physics at a German grammar school, I have been responsible for ICT and teacher trainings in this field. Since 2001 I am assistant professor at the University of Würzburg and teach students that become mathematics teachers. My Ph.D. theses was about "kinematical thinking". That´s the part of mathematical thinking that is necessary for a reflected use of dynamic geometry systems (DGS). In the last years I organized and held teacher trainings concerning the use of DGS in mathematics lessons. I developed learning environments based on DGS and tested many of them in schools. In addition to that I work with small teams of teachers (namely the AK DynaGeo and the AK GeoGebra). We try to enhance their professional knowledge in connection with the use of DGS in the classroom and the conception as well as the development of learning environments based on DGS. Some of the results can be found under the following addresses:

Recently I am developing a mathematics-laboratory for students of higher secondary level. They deal with real objects (or models of them) like diggers and in addition to that DGS-based simulations of those objects. The intention is, that the students understand the mathematical content of these objects and solve problems appearing in connection with those objects using mathematical methods. Further information about this project can be found under the following address:
