Evidencia de un obstáculo epistemológico

Abstract

The purpose of this papel' is to show the importance of the notion of epistemological obstacle in thc construction of mathematical concepts and how these obstacles can be identified in the students through study of the recurrent mistakes and of the historical development ofthe mathematical concepts. It is shown an example of an experience of evidence of epistemological obstacle, related with the mathematical concept of tangent right at a curve. This experience makes part of the research work "The Euclidean Obstacle on the Construction of Tangent Concept", presented by Sergio Alarcón Vasco and Carlos Suescún Arteaga for to reach to Magister degree in Mathematics Education in the University of Antioquia, and it is framed in "An Alternative Metodologic for the Teaching and Learning of the Concept of Limit" research project, COLCIENCIAS 1115-11·12704, developed by the "Educación Matemática e Historia" research group of the University of Antioquia and EAFIT.
