Uso de recursos computacionais no processo de ensino e aprendizado na teoria de polinômios na educação básica

Abstract

This paper studies the actions and the results from polynomials teaching through computational tools in the last year of secondary school. The methodology is based on a constructivist perspective, focusing on computational tools used in an interactionist way. Firstly, we analyse the usage of new technologies in education, giving special attention to videos and to the software GeoGebra. Secondly, we analyse the actions taken in teaching episodes, as part of a case study, which were transcribed and registered by the students as an evaluation activity. Preparing the activities, we considered how to use videos and GeoGebra in the construction of knowledge and, for interpretative analysis, evaluating how the abilities and skills were acquired in polynomials studies. By the episodes, it was made evident that, through using computational tools, it is possible to go farther as we study polynomials, including deriving and determining the equation of a tangent line to a polynomial.
