I'm* two rabbits / J'ai un rouge pullover*. How corrective feedback is handled in collaborative exchange programmes between early language learners

[EN] This article presents how, in the social dynamics of two classrooms involved in an exchange programme, young learners provide their peers with asynchronous feedback taking place in the digital medium. Within two Call Triangles that interact thanks to Computer Mediated Communication tools, teachers sharing the same methodological precept on learning processes give more autonomy to the learners. Here we focus mainly on a salient fact to show how they make use of this freedom.
