The articles published in "D & S" concerning the creation and operation of remote training methods can be characterized according to the points of view taken by experts or researchers. The authors are interested in three particular aspects of the training process: organization, design, and impact. Different approaches in the design of these methods determine the economy of their structure. They may include certain constraints, such as when a team has a specific and voluntarist vision or when seeking safety by keeping to the norms, or, on the contrary, to pragmatic approaches consisting in adapting to the situation. All the proposals focus on a central theme: supporting students from a distance. (Contains 1 table.)
