Modelagem matemática como metodologia alternativa para o ensino de função quadrática

Abstract

The present work addressed the application of Mathematical Modeling as an alternative methodology in teaching the quadratic function in high school, through real situations. Initially, concepts and ideas about mathematical modeling and its stages are presented. Then, this methodology was adapted, following the same reference, for teaching the quadratic function in a 1st year high school class of the Technical Course in Computer Networks at the Federal Institute of Amapá. In this approach, a diagnosis of the students' learning level was carried out and, based on this, technical revisions were promoted on the content of the quadratic function. Subsequently, a mathematical modeling activity was applied with everyday examples related to the quadratic function, following the steps of mathematical modeling. With this application, it was noticed that the students learned more meaningfully, reflectively, critically, motivating and relevant in relation to the content. This finding is corroborated by the analysis of a questionnaire answered by the students themselves, about the applied methodology, and by the observations made in the final considerations.
