The objective of this work is to present preliminary results of a study about the situation of modelling in Spanish secondary education and a proposal of action. Within the framework of anthropological theory we will show, through the analysis of the official syllabus, that modelling is knowledge to be taught. Despite this, after an analysis of official texts, we have observed that didactic formation of secondary teachers is very poor. Through an experience, developed and implemented in classroom by one of the authors, we will show a different way to work modelling tasks in secondary education.
