Recent approaches to second/foreign language teaching introduced by the CEFRL include a special emphasis on conversational interaction. Implementing new communicative, functional and intercultural approaches undoubtedly requires paying attention to this textual typology, whose study is relatively scarce, both in language sciences and language didactics. For this reason, our paper aims to offer some courses of action in language didactics partly derived from a research on conversational exchanges and the role of interruptions.
