Titre de la communication :	Animated lessons with TI-Interactive
Résumé de la communication :
TI-Interactive is an ideal software to teach and learn mathematics. Some of its characteristics as the automatic updating of documents and the existence of sliders allowing to change the values of parameters, makes TI-Interactive an excellent tool to illustrate the different situations that eventually occur in a given problem. Moreover, as TI-Interactive is simple to use even for a secondary school student, worksheets can be passed on to the students, completed by them then passed on to the teacher again, all this, in the same environment. These worksheets may contain various links to other documents (partial solutions, hints, additonal informations, ...) that the students are free to consult according to their own needs. This gives them the opportunity to work in a relatively autonomous way. In our presentation, we will illustrate the various characteristics of TI-Interactive indicated above on the following two subjects that have been experimented in secondary school classes (16 to 18 years old students). The tale of the horse and the cheetah : taking as starting point the equations relative to rectilinear movements with constant velocity or with constant acceleration, the problem consists in simulating a situation in which a cheetah is pursuing a horse and in determining algebraically and graphically the issue of the pursuit. Can you imitate the flight of a bird ?: in this work, the students are asked to simulate the flight of a bird using appropriate parametrical functions.
