As did the conference, the special issue reflects our attempts to advance research on language classroom interaction and foreign/second language teaching by promoting the dialogue between scholars working in the fields of Conversation Analysis (CA) and language teaching research. Language teaching research is increasingly interested in the learning process as a social accomplishment and thus in the interaction that takes place in the language classroom between teachers and student(s) as well as among the learners (e.g. Schwab, Hoffmann, and Schön 2017; Limberg and Jäkel 2016). CA research provides suitable empirical tools for the investigation of classroom phenomena. At their intersection, empirical studies provide information on the interactional processes involved in language teaching and learning, which can ultimately inform language teacher training and contribute to its increased professionalization. This special issue further aims to build bridges between research traditions in a geographical sense in that it brings together work by scholars from Europe and North America. By showing that scholars in different parts of the world are working on related issues, and by making this work openly accessible, we hope to contribute to overcoming some of the obstacles which the use of national languages and platforms for scholarly publications occasionally entail. Interaction-oriented classroom research has gathered great momentum internationally, and we believe that the community stands to gain much from leveraging those synergies. All of the five papers collected in this issue take a conversation-analytic approach to analyzing second/foreign language (L2) classroom interaction and strive to make their findings useful for teacher education. Accordingly, we will briefly introduce the CA-for-SLA approach as well as conceptualizations of CA-based teacher training before previewing each contribution and their implications for teacher education. Conversation analysis and (second) language classroom interaction Using CA to investigate interactional phenomena in second/foreign language classrooms with the aim of raising teachers' (educators') 'awareness of the interactional dimensions of language use in context' (Firth and Wagner 1997, 286) is in line with the CA-for-SLA (Second Language Acquisition) tradition.
