Hans-Leinberger Gymnasium has its focus on mathematics, science, economics and foreign languages. It was and still is deeply involved into the education of teachers in mathematics, physics, science and foreign languages. It is the Regional Center for Further Education and Training of Teachers and, in this role convenes many in-service teacher training workshops, which makes it an ideal partner in the project. The school has a long standing experience of the use of technology such as CAS-handhelds within mathematics and science. Currently the schools is taking the leading role in the coordination of the Bavarian M^3-project (Model-Project-Media-Mathematics), which develops ideas and strategies to integrate hand-held-computers into mathematics lessons.
Ewald studied mathematics and physics and has taught for 10 years at a German Gymnasium. He is a long-term member of a working group of Bavarian teachers who work closely with the Bavarian Government of Education. In the early days of its development, this group developed materials for the integration of computer algebra systems into mathematics classes in Bavaria. For three years, he has been the coordinator of the Bavarian M^3-project (Model-Project-Media-Mathematics), which develops ideas and strategies to integrate handheld technology into mathematics lessons and the associated teacher training. He runs an Internet-platform (BSCW) for the communication of these teachers.
