Comprender el trabajo de los docentes a través de su interacción con los recursos de su enseñanza – una historia de trayectorias

Abstract

© 2018 Mexican Society for Research and Dissemination of Mathematics Education. All rights reserved. This article shows, from a personal testimony, how the technological, conceptual, professional and human histories are intertwined and illustrate this interrelation from the trajectory of a resource. In the first section that testimony is presented. The second one exposes the conceptual framework in which our research is currently located. In the third, the mathematical problem that underlies our reflection is introduced. The fourth section is devoted to the implementation of this problem in a context of teacher training in France in 2002. The fifth section is intended to the analysis of the same problem in the context of a research seminar in Mexico in 2017. In the sixth section the tensions related to teacher training are highlighted, between "giving them tools to support their work in the classroom" and "giving them time so that, together, they can express their creativity". This article takes up, in particular, the terms of a seminar that was held at the Freudenthal Institute of Utrecht, at the invitation of Paul Drijvers (Trouche 2018A).
