Didactical Adaptation of Professional Practice of Modelling: A Case Study

In this chapter, the aim is to study the possibilities of giving to students the responsibility for mathematical work that makes it possible to make an extra-mathematical situation accessible through mathematical treatment. I briefly present the elements of a first epistemological study of researchers’ modelling practices. I show how I used it to design, implement and analyse a situation for teaching and learning mathematical modelling, based on an adaptation of a professional modelling problem on tree growth prediction.
