Résumé de la communication :
A group of five Computeralgebra System experts formed a "TI-Special Focus Group" to produce a book, which should convince reluctant teachers and school authorities as well to permit and support introducing handheld computeralgebra in mathematics education. Colleagues from Scotland, Belgium, Switzerland, Denmark and Austria cooperated in gathering, selecting and commenting teaching units and assessment examples. They also tried to show the way how to prepare the students for technology supported exams. Valueable additional contributions from France and Australia accomplish the product which is embedded in a rich didactical discussion. Guido Herweyers, Belgium and Josef Boehm, Austria will present the exciting history and the results of this challenging project.
