La mathématisation horizontale : quels apports pour une recherche sur l’enseignement et l’apprentissage de la modélisation mathématique ?
Résumé
In this article, we are interested in mathematical modelling based on extra-mathematical situations. Starting from such situations requires first to make them accessible to a mathematical treatment. We show how we have considered the work of horizontal mathematization and its dialectical relationship with vertical mathematization, in a modelling process, in order to carry out a study on the devolution of horizontal mathematization to secondary school pupils. The objective is, on the one hand, to show how we have taken into account the work of horizontal mathematization throughout our research, and on the other hand, to highlight the contributions of this consideration in our didactic analyses.
