Compreensão de conceitos de geometria a partir da construção de sólidos geométricos em uma turma de EJA de ensino médio

Abstract

This monograph brings results of an investigation carried out in the classroom, with students of adult education (EJA), from activities involving the contents of Spatial Geometry. The main objective of this research was to investigate what students knew about Euler Relation, Total surface area and Volume of the main geometric solids, as well as about your posture to learning of such content. When analyzing the results we can point out that the students ' knowledge and understanding in relation to the content listed above, are few. Although the vast majority of students have already studied previously concepts related to plane geometry, few were able to relate this content, with the total surface area of geometric solids. In relation to the calculation of the volume of solids, for some students was more quiet, since they work in places where they need to master these contents. In relation to the contents worked was carried out, on the first date, an activity to see what students knew about such content. He was also asked to do a research paper about the same. On the second date, were built some solids, using concrete materials. These solids were prepared by students, with the intention that view faces, edges and vertices and to realize the relationship between the planned and spatial format. In addition, some formulas and definitions were explored related to: Euler Relation, Total Surface Area and Volume of some solids, like for example: the cube, the cobblestone, the cylinder, among others. At the third meeting, was held a group activity involving the proposed content. With this study it was possible to notice that it is possible to work the math content differently and, although students have had difficulties, these activities awakened most interest and her math and better understanding of the content.
