Análise de livros didáticos: geometria no ensino fundamental

Abstract

This document analyses the bibliography used in the math classes of the Fundamental Teaching II stage of the Brazilian educational structure in terms of the presence or not of the Geometry subject, as much as the approach used for the specific topics contemplated in this subject.The studied didactic books contemplate works since the 70s until the 2000 decade, including both complete collections and partial ones, due to the difficulty of finding dated books for the oldest collections.Firstly, a brief study is performed of the Brazilian education laws aiming to contextualize the analysis to be further realized, contemplating also the changing of the duration of the Fundamental Teaching regime from 8-year period to 9-year period, which took place in 2006.Next, a discussion is performed of the technical approach of some works in contrast to the mainly didactical one of the others, frequently related to the date of publication of the item. The existence of differentiated activities in the later works, such as folding and manipulation tasks, and their impact in the learning process of the student are also commented.Finally, a reflection is presented on how other factors, such as the background of the teacher and the interest of student, might contribute to a deficiency in the learning process, even while using good quality books.
