Análise da organização didática da geometria espacial métrica nos livros didáticos

Abstract

This work had as objective to investigate which the organization that the didactic books of Mathematics destined to 2ª series of Average Education make, referring to the subject Metric Space Geometry, and if this organization favors the construction of the geometric thought. For in such a way, the subject was searched in available literature, official documents, dissertations and theses defended in Brazil and articles of national and international congresses. They had been analyzed three of eight books of Mathematics sent for 2ª series of Average Education for the National Program of the Book for Average Education, 2006 of the Ministry of the Education and Culture, to the schools of the Direction of Education of São Bernardo do Campo - SP, according to resulted of the research of: Duval (1995), Robert (1998) and Parsysz (2000). The analysis of didactic books had as purpose to verify if the activities for them proposals provide and favor the construction of the knowledge on the part of the pupils, considering activities with use of material concrete, constructions with instruments as ruler and compass or softwares that they facilitate the visualization and they develop the space geometric thought. One concluded that the analyzed didactic books take care of partially to the construction of the geometric thought, because the results of the research indicated to little exploration on the part of the authors of activities that develop the visualization, the representation in the plan of the three-dimensional figures are not stimulated. A balance with regard to the number of considered exercises that demand the levels technician and mobilized and a discrepancy with regard to the available level and to the lack of activities was evidenced that can be developed by educational software, contributing in this way for the diffusion of a vision maken a mistake of the teacher on the education of Metric Space Geometry
