O ensino de funções do 2º grau com o uso do Software Geogebra: uma experiência no 1º ano do ensino médio

Abstract

This study aimed to develop a teaching research using the Geogebra Software for the content of Quadratic Functions in a class of the 1st year of High school. It was used a case study with a qualitative approach, which was developed in a school of the state education system, which is located in Cuitegi city, Paraíba state. Four our reasoning on the Quadratic Function content, we souglit guidelines in some official documents, such as National Curricular Parameters of High School (PCNEM), and Curricular Orientations for High School (OCEM), some references about the use of the technologies were made emphasizing the Geogebra Software. Two activities were applied to the class, the first activity was a diagnostic assessment as an introductory part of this research, from that, it was possible to verify some previous knowledge of the students (of the class), related to Quadratic Function content. That assessment was divided into two parts, the first one with questions about the Quadratic Functions in an algebraic way, and the second one with contextualized questions. After the diagnostic assessment, it was possible to identify the difficulties of some students, and that served to develop the second activity. The purpose of these activities was to motivate the students construct, manipulate and visualize possible solutions of their activities, using the technological resources that the software offers. At the and of this study it was possible to conclude that the contributions and possibilities brought in this research to these students, using a technological resource of great importance, making the students perceive a different way of learning and that they develop a better performance in their learning.
