Limite e continuidade: Um enfoque acessível ao Ensino Médio com o auxílio do Geogebra

Abstract

This study sought to develop a teaching sequence capable of narrowing the contents of Limits, Continuity and the Intermediate Value Theorem for use in secundary education classes. For this purpose, didactic separate proposals were built for these themes, which were applied to students of Secondary Education of the Nicanor Souto Maior School. The application analysis of the proposal pointed out that the use of the sequence is viable from a didactic point of view, the possible inclusion of these contents in secundary education. As for the difficulties to develop the proposed activities without the help of GeoGebra, these were identified mainly on the construction of the graph, as has been reported in the literature. The GeoGebra proved to be a significant tool to assist in the construction of such contents. Were proposed for future studies, research projects that identify mathematical activities that may be strengthened with the use of GeoGebra and researches that could results in new teaching situations that may relate in an interdisciplinary way many areas of knowledge.
