In the framework of Licence-Master-Doctorate reform we undertake an exploratory study on the relations that should be established between mathematics and the didactic of mathematics, under the double aspect of content and training approach. For this purpose, an interview questionnaire is designed around questions stated in the call for contribution of GT1; five math trainers and five trainers of math didactic have been interviewed. An analysis of collected answers allowed us to identify some ways for a restructuring of the two types of training according to the recommendations related to LMD.
