A construção do pensamento geométrico: visualização e análise dos quadriláteros

Abstract

This research aims to investigate the construction of geometric thinking in a class of 9th grade of elementary school. The survey was given by curiosity to investigate how these students conceive the content of Quads. For reasons of research in embasamos in authors like Van Hiele (cited Walle, 2009) Van de Walle (2009), Rêgo and Rego (2012), Cirléia Barbosa (2011), Lorenzato (2012), the National Curriculum Parameters and other authors. For construction activities, implementation and analysis of the results had the theoretical development of geometric thinking model developed by Van Hiele double that deals with this development in five levels. For our research we use a priority only viewing levels and analysis. The implementation of activities occurred in 6 hours / class, a class of 9th grade of elementary school, to conduct the survey participated in average class 22 students. During the research we observed the development of skills in geometric visualization of students and building settings Quads. With the analysis of the data concluded that research has shown the expected results, the students were able to advance from one level to the next with grip on the first level, level 2 noted that they were able without difficulty to define some important properties of each quadrilateral.
