Una propuesta didáctica para mejorar la comprensión del concepto de límite de una función

Abstract

Abstract. This writing is part of a research work in Educational Mathematics aimed at characterizing basic concepts of Calculus. This article is the result of a longitudinal study with different groups of university and postgraduate students, where difficulties are observed to work properly these concepts. After a review of publications related to the subject, it determined to use the referential frame "Concept Image” and “Concept Definition" of Tall and Vinner (1981), to elaborate a series of didactic activities, which are supported by a Software of Dynamic Geometry. These activities help to promote the understanding of the limit concept of a linear function and result in a richer mental image in students.
