O processo de ensino-aprendizagem dos poliedros

Abstract

Nowadays it is possible to notice that most of the students arrive in the 6th year with difficulties in visualizing the elements of a polyhedron by virtue of the form taught from the initial grades improperly. In this work will be carried out an approach of diverse constructions of polyhedra of playful form that can be used in the Mathematics classes of Elementary School II and High School, aiming at the better understanding not only of the elements, but also of the concepts related to these solids. In addition, an innovative didactics will be presented with the use of augmented reality (RA) in the classroom through educational softwares that make Space Geometry classes more dynamic, interactive and enjoyable and also allow to work the Euler Interface in a differentiated way. We believe that in this way we will provide meaningful learning of polyhedra. On the other hand, we will highlight the geometric development model and the learning phases developed by Van Hiele. To finish this work, activities were applied to 22 students of a 6th grade class. These activities took place in two parts: an activity performing constructions of polyhedra and another activity with augmented reality through the use of the applications: Polyèdres augmentès and Geometrix to approach the content through technological resources and to diagnose where the difficulty presented by the student in the learning of polyhedra resides.
