CaRMetal : une géométrie dynamique enrichie

Abstract : The following paper gives a didactic account of the handling of the various concepts offered by the CaRMetal program. It helps us understand the meaning of the systematic anticipation of all the tools, the operationality of generalised a-modality, the pertinence coupled with direct manipulation and its extension to finite structures, the breaking away from determinism through figures immersed in the user’s time, the increased direct engagement resulting from it together with a form of enriched determinism made possible by the merging of magnetisation and recursivity. Then, with the integration of Javascript we are informed about such specific utilisations in school as algebraic investigation with detected dynamic geometry. Finally, we will reverse to time and see that animation respects the temporality in which figures may be immersed.
