Estudio sobre el proceso de conceptualización de la función exponencial

This paper describes the process of conceptualization of four groups of pupils in high school (121 students around the age of 15-16 years), and the way they study the conceptual field of exponential functions with a dynamic of study, in which the first aim is the participation of the pupil in the construction of knowledge. The theoretical constructs proposed by Vergnaud's...

Teselaciones para niños: una estrategia para el desarrollo del pensamiento geométrico y espacial de los niños

The present article describes the elements that are immersed in the didactic proposal Tessellations for Children, as a class alternative, that has been developed in the school with preschoolers and the primary school children (between 5 and 11 years old) since 2004. It appeals to the job with tessellations (artistic creations with regular or irregular polygons that repeated on...

Análisis de situaciones de aula en el contexto de la práctica de investigación: un punto de vista semiótico

Much research in mathematics education presents analyses of classroom situations that are the result of research or experimental praxis generally linked to negotiation of meaning between the teacher, who refers to institutional knowledge, and the student. The focus of this research is not always related directly or consciously to semiotics, but even when this does not happen it...

Estructuras argumentativas de estudiantes para profesores de matemáticas en un entorno en línea

The goal of this study was to analyze how pre-service mathematics secondary teachers learn to analyze the mathematics teaching as an aspect of teaching expertise. We analyze pre-service mathematics teachers' argumentative structure in online discussion when they are learning to notice relevant aspects of mathematical communication in mathematics teaching. We use Toulmin's...

Actitudes matemáticas: propuestas para la transición del bachillerato a la universidad

In the last decade, research in math education has highlighted the variety of factors that influence the transition between secondary education and higher education in mathematics. A positive attitude toward mathematics and, in particular, toward the confrontation with complex math homework, is fundamental to initiate the students in the resolution of mathematical problems. This...

Ecuaciones diferenciales ordinarias con Maxima

In this work we present solutions of ordinary differencial equations by using the open source package Maxima. The basic commands of solutions of this package are explained by a set of selected examples taken from trraditional courses in ordinary differential equations. Here, some of the strengths and the weakenesses of Maxima as a teaching tool in an ode's course exposed. We hope...

La razón y la fracción: un vínculo difícil en las matemáticas escolares

The role of the notion of ratio in the primary school mathematics, especially that of its link with the notion of fraction, are not clearly defined in the curriculum, at least in Mexican's one, nor in classroom teaching. We share the point of view that attributes these difficulties mostly to the genesis of these notions, as well as to that of its teaching. In the first part of...
