Geometria espacial: transição do plano para o espaço com o uso da Pletora de Poliedros

Abstract

This study aimed to verify and analyze the difficulties encountered by high school students from the State School of Santana do Livramento, in 2010, figures to identify and interpret spatial problems involving them. In this sense, students participated in the investigation of the third year of high school and elementary school teachers and high schools. Initially there was, how teachers approach the study of geometric concepts in elementary school, since students need when making the transition from plane geometry to the space are numerous difficulties, and later from questions posed to teachers of elementary and high school was found that geometrical concepts are poorly developed, and we need a tool to facilitate the transition from plane to space. The strategies included the use of software Plethora of Polyhedra, which is an interactive website that allows students to interact with spatial figures, checking their schedules, edges, vertices, faces, etc.., Favoring the transition from plane to space. From the use of the Plethora of Polyhedra realize that students can visualize the spatial figures starting from the plane figures and relate these perceived characteristics and properties, facilitating the interpretation of problem situations in the classroom conducted involve areas and volumes of geometric shapes space.
