After identifying a major limitation of current research on telecollaboration, I propose to develop a methodological framework to empirically study the link between the sociocultural dimension and the linguistic dimension of interaction in eTandem via desktop videoconferencing. For the sociocultural dimension, I study which roles the learners take during the interactions using discourse analysis tools. For the linguistic dimension, I focus mainly on different types of conversational side sequences identified in the francophone interactionist literature. In the end, I discuss the relevance that the methodological framework I propose can have for research on telecollaboration and point to studies that explored this avenue.
