This issue of Cahiers Ramau questions the connections between training courses and their socio-professional context. By making use of both theoretical insights and / or accounts and experiences, we examine current training courses in relation to practices and theories in environmental transformation (urban planners, architects and landscapers in particular) due to numerous decompartmentalizations (evidenced by the popularity of design thinking in the educational sciences) and a certain academic redisciplinarization. The call for papers on this issue was focused on three axis ; the training curricula, the training and professional standard references, and the social construction of professionals. Twelve texts were selected, organized in four parts.
