 The construction of value through work-integrated learning 
Pedagogy is part of a training relationship. It is characterized by an intention to develop the person and to mobilize a configuration of knowledge. The way of implementing produces the matter of the development of the persons and makes the value of the training. In this contribution, we analyze a training system that includes two populations: young apprentices and adults in professional activity. A quantitative and qualitative survey highlights the negotiation of knowledge that takes place in the course and in the action. We demonstrate how value is constructed for the learners and how the pedagogy is implemented.
