Uma Sequência Didática para explorar a regra de L`Hospital com o uso da Tecnologia

Abstract

t presents an Didactical Engineering – DE, with situations involving the issue of education, in the context of the use of L'Hospital rule, in the course of a degree in Mathematics from the Instituto Federal de Educação, Ciência e Tecnologia do Estado do Ceará - IFCE. The phase of experimentation and validation of DE is supported in the teaching methodology nominated Fedathi sequence. Thus, there has been a research climate in two activities, with the participation of four pairs of undergraduate students in Mathematics, in which the use of GeoGebra proved essential. In the subsequent analysis, include: the exploitation of software, students compare the datas with the geometric nature of the analytic-algebraic nature, the software enabled an understanding, through the didactic nature of mediation, the manifestation of indeterminacies in nature geometric, and avoid the unthinking application of the rule, which the applicant is a teaching that is limited to the algebraic framework.
