O ensino de figuras tridimensionais no 6º ano do ensino fundamental: contribuições do modelo de Van Hiele

Abstract

This paper is a part of the work to finish a specialization course that aimed to analyze the contributions of a sequence of activities, of Van Hiele model’s based , for the development of the geometric thinking of sixth grade students at an Belo Horizonte city public school . These activities were developed in such a way that students have explored objects and drawings that represented three-dimensional geometric figures and communicated their ideas, writing and orally, with and to their colleagues and also to the teacher. Students were free to express themselves using their words so that geometric concepts and terms were being constructed and refined throughout the application of the sequence of activities. The research data have been collected through notes made in a field’s diary containing descriptions and impressions about the development of the tasks, student records, photographs and video footage of the classes. The analyzes allow us to assum that the students have advanced in Geometry’s learning , and several of them have given us evidence that they have advanced from the visualization level to the analysis level.
