Contextualizando o ensino das parábolas

Abstract

This paper was developed in order to guide and enhance the study of Quadratic Function in a class of first-year high school students at a public school in the city of Juiz de Fora, Minas Gerais. At that school, most students finish the theoretical study of the function without relating it to practical elements of daily life. However, it infers that such a link facilitates the learning process. Consequently, it will be developed a proposal of teaching that, in addition to accomplish the theoretical approach, it will dimension the study a little more in practice, providing glimpse and understanding of the Parabolas in the students’ day-to-day. Thus, based on the National Curriculum Standards, the teaching plan will present a historical approach, the formal description of the topic in question and its contextualization. Therefore, it is expected that students can significantly understand it and that they can be able to find efficiently solution to the situations problems determined by the graph of a Quadratic Function. However, this proposal does not intend to be a guide in teaching of Parabolas, although it suggests a possible way to establish the teaching and learning of these curves more meaningful for students.
