The number of online environments language teachers can employ is constantly growing, offering increased potential for multimodal L2 interaction analysis. This paper introduces the LEarning and TEaching Corpora (LETEC) methodology that links, following international standards, all elements resulting from an online learning situation, whose context is described by a pedagogical scenario and a research protocol. The corpus components include the learning design, the research protocol, the interaction data, all participants’ productions and licences relating to ethics and access rights.
