The Use of Concrete Artifacts in Analytic Geometry: the Ellipse Experience

The purpose of this article is to provide the results of a research on the use ofspecific artefacts (two different ellipsographs) for the learning of Mathematics,specifically in Analytic Geometry on the topic of Ellipse. It was implementedone activity for each one of the artefact, by means of the use of working sheetsthat guided the students for tem to build the formal concept of Ellipse, answeringto the corresponding questions in each activity as well as manipulating theellipsograph. All with the aim to facilitate to the students the understanding andlearning of the mathematic concepts. Keywords: analytic geometry, ellipsograph, collaborative learning
