Utilização do GeoGebra na modelagem matemática: uma análise e proposta de ensino de funções quadráticas para o 9º ano do ensino fundamental

Abstract

The teaching of mathematics requires the teacher to be able to explain concrete and abstract concepts and ideas. Currently, providing an understanding of algebraic content has become a major challenge. In this research, we analyzed a way to demystify content that most students consider complex. Based on the theory of meaningful learning, we will show the possibility of carrying out mathematical modeling when teaching quadratic equations to 9th-grade classes in Elementary School. Using the GeoGebra software as a tool can enable the student to visualize the proposed content, leading him to build knowledge dynamically. We will present important theoretical concepts as a basis for the research. We will analyze works that were carried out empirically with the proposed theme. These will be explained and, in the end, a proposal for teaching quadratic equations that uses mathematical modeling and GeoGebra software will be shown, seeking to provide meaningful learning.
