Sistema de equação linear: um estudo de sua abordagem nos cadernos do professor de matemática de 2008 e 2009 da rede pública de ensino do estado de São Paulo

Abstract

The aim of this documentary qualitative research is to investigate how the content from the "Linear Equations Systems in Mathematics Teacher's Notebooks from São Paulo's public schools (from 2008 and 2009)" is covered. Our interest about this research started when the Pedagogical Mathematics Report (2010) was presented. In this report, they affirmed that high school students present more difficulty to learn Mathematics than elementary school students do. To develop this paper we have researched the official documents, to see what they recommend in teaching linear equations systems to high school and elementary school students. For comparison, we have also explored two didactical Mathematics book collections. We have found out that Mathematics Teacher's Notebooks from São Paulo's public schools (from 2008 and 2009) use an approach that is similar to didactical books; the biggest difference has been found in materials dedicated to high school. While didactic books teach subjects followed by exercises, authors from Mathematics Teacher's Notebooks from São Paulo's public schools worry more about contextualizing the subject to student's realities. The aim of this paper is to propitiate an analysis of Mathematics Teacher's Notebooks from São Paulo's public schools from the 3rd bimester from the 8th year in high school and the 2nd grade from the 2nd year in high school referring to teaching linear equations systems. The product of this analysis can be found separately from this paper, and it is available online at www.pucsp.br/pos/edmat
