Titre de la communication :	REPRESENTATIONS AND GRAPHIC CALCULATOR IN MATHEMATICAL TEACHING. A STUDY WITH CALCULUS TUTORS
Résumé de la communication :
A group of Mathematical Tutor´s productions, who participated in a Formation Program, based on the use of Representation Systems and Graphic Calculator in the teaching and apprenticeship process of Differential Calculus, are analyzed. The mentioned Program was implemented trough a course- workshop. The participants in the study were Mathematical Tutors from the basic cycle of the Economical and Social Sciences Faculty of the Carabobo University, La Morita Nucleus in Maracay, Venezuela. The participants productions, withdrawal from their note books and reflections emitted by the tutors, at the end of every working session, are analyzed from a qualitative perspective. These productions analysis, concluded that the tutors showed up changes in the Didactic Knowledge, expressed in their reflections and productions during the activities carried on. It likewise, manage the participants to apply the representation systems, systematically, in the resolution of problems with the graphic calculator assistance, and also identified options for the Differential Calculus Teaching. Key Words: Graphic Calculators, Representation Systems, Mathematical Tutors, Differential Calculus, Didactic Knowledge.
