Considerações sobre o ensino de funções no ensino fundamental e a linguagem matemática

Abstract

The study of Functions is one of the main contents of the 1st year in the High School, but the basis of information for a good understanding of this subject begins in the final series of the Elementary School. During this period, the student needs to familiarize himself with the different ways of writing in mathematical language and substantiate initial algebraic concepts, correlating them with the daily life. However, without a good understanding of the rules of this language (which are different from a natural language), the student has several difficulties, both in understanding the presented concepts and also in making the necessary correlations. Based on the author's experience in a municipal school in Rio de Janeiro, with classes in the final years of the Elementary School, the present study aims to suggest improvements in the teaching of contents related to Functions, as soon as possible, mainly presenting properly the mathematical language. For this, an analysis of the basic curricula and for some materials of the Elementary Education, present in this school, was carried out in order to elaborate and present possible interventions that aim to reduce the difficulties observed in the classroom, helping the student to understand more of the mathematical language, through the study of your grammar
