Reflexões quanto à importância das construções geométricas no ensino da Geometria Plana

Abstract

The present work was carried out in three stages, which are the theoretical, research with professionals of education (mathematics teachers from public schools in the metropolitan region of Rio de Janeiro) and performing diagnostic and educational activities at the Municipal School Cruzeiro do Sul, Mesquita, Rio de Janeiro, with students from the 6th grade of elementary school. The work has shown promise in identifying a strong tendency of mathematics teachers in this region promote their practice in teaching Plane Geometry, highly influenced by a process algebrization this science and its teaching. This study aimed to promote reflection on the current teaching of Plane Geometry in elementary school in the metropolitan area of Rio de Janeiro, as well as provide a strong tool to minimize disability in its teaching. It is speculated, with strong evidence, that the abandonment occurred in Brazil, particularly in the region where the study was promoted, the use of Geometric Constructions in teaching plane geometry is, perhaps, the main factor that affects the teaching and learning of this discipline.
