This is an abstract of a presentation at The 8th International Congress on Math Education (ICME 8), July 14-21, 1996 in Seville, Spain.
Cabri-geometre is an interdisciplinary project developed jointly by computer scientists, researchers in didactique and mathematicians from the French National Center for Scientific Research and from the University Joseph Fourier in Grenoble. It aims at developing a computer-based microworld designed to facilitate the learning of geometry. The key concept is the possibility of direct exploring possibilities, as if the standard paper-pencil environment would have been replaced with a much more powerfull medium, where geometrical drawings that have been contructed can seamlessly been reshaped just through the mouse. Recently the "Dynamic Geometry" technology as been implemented, as Cabri II, in a novell hand-held pocket calculator the TI-92. We will show how this can provide teachers with new tools to make connections through geometry, algebra, calculus and physics in the more global approach of Microworld with Direct Manipulation.Jean-Marie Laborde, Jean-Marie.Laborde@imag.fr
