O desenho geométrico no 9º ano como estratégia didática no ensino da geometria

Abstract

This research aims to present part of the history of the Geometric Design history in Brazil, passing through significant historical moments, that played a very important role in the development of nowadays Geometric Design, searching for its importance, as well as what it‟s into the National Curricular Parameters (PCNs).The Van Hiele's Theory is presented through its different levels and how the teacher can use this theory and provide a better use of learning in Geometry. The works shows a previous and posteriori evaluation to diagnose the level of geometric learning of the students before and after the activities proposed in this paper, with reference as evaluation criterion the Theory of Van Hiele. Some activities were applied in a state school in Arapiraca-AL, with a 9th grade class, which involved basic geometric constructions to aid in the learning of Geometry. As results some considerations were taken into account about the activities that were proposed in the classroom and how they could help in the process of teaching and learning Geometry.
