Dois jogos de linguagem: a informática e a matemática na aprendizagem de função quadrática

Abstract

This research was conducted in order to identify and analyze the relationships between the languages of Mathematics and Computer Science in the context of the classroom, from the integration of information technology in learning the Quadratic Function. Therefore, the concepts involving algebraic form and graphic form of this function were observed by students as they explore the dynamic aspects of the interface Geogebra. The theoretical research was subsidized by the ideas of Pierre Lévy on intelligence technologies in the dissemination of information and knowledge, as well as the philosophical contributions of Ludwig Wittgenstein about language game. The research methodology has qualitative character set from specific criteria about the object of study and the subjects investigated. The information was obtained by means of specific questions applied in two stages, namely: before and after conducting a short course on GeoGebra. Analyses of questioning revealed that the visual aspects and movements in computer use, establish relationships between the algebraic and graphical forms of the quadratic function. However, they might realize that the numerical coefficients modify the parable and it gives meaning to the concepts studied. The use of GeoGebra allows other forms learning evidenced between the game and the Language of Mathematics Game Language Informatics in Education Mathematics.
