In May 2020, at the end of the Covid-19 confinement, the French government implemented an operation called “Colos apprenantes”. In such a context, it seemed particularly important to allow as many children and teenagers as possible to leave their homes for the holidays. These summer camps, organised in a collective framework throughout the country, were intended to enable young people to reinforce certain learning activities while benefiting from leisure activities. This article proposes to analyse the operational implementation of this scheme through the filter of the “mediation” operator, the latter being understood as a vector of interactive dynamics and sociability.
