Resolução de problemas envolvendo função de segundo grau: uma análise dos livros didáticos da primeira série do ensino médio

Abstract

This work presents a research with two textbooks used to teaching Mathematics in the 1st grade of high school in two state schools in the city of Mamanguape / PB. Considering the importance of this didactic material in the classroom, for offering a pedagogical support regarding the verification of contents that should be studied in each series. The study was developed to know how this teaching material presents the content of Quadratic Function and how the exercises are presented, observing if these correspond with the main indications of the official documents that govern the teaching, more specifically of Mathematics. The objective of this research was to investigate whether the analyzed books deal with content through Problem Solving. The methodology used to develop the research can be characterized as exploratory. Regarding the methods used, it is characterized as a bibliographical documentary. The literature presented in this research sought to base the historical course of the textbook in Brazil, bringing the main moments of its consolidation. Showing the teaching through Problem Solving and indications of how the official documents of curricular orientation indicate for the teaching of Mathematics. The results perceived in this work showed gaps in the approach of the problems and little contextualization that brings Mathematics closer to the reality of the student. Proposing that the textbook should be chosen with great care, since this should contain in a summary approach to problems that condition the student to build knowledge in addition to promoting autonomy to think. Leaving a space for other researchers to point out ways that condition the improvement of Mathematics teaching.
