This dissertation presents a study on teacher-educator interactional identities in English language education. The study extends Conversation Analysis by doing co-analysis and member-checking with three participating teacher-educators to analyze the enactment of their interactional identities in language-based and content-based classes in three different undergraduate programs in English language education. Findings discuss the presence of multiple interactional identities composed of varied forms of being and doing as interactants in the occurring organizations of classroom interaction. These findings highlight the relevance of studying teacher-educator interactional identities to explain how English language education occurs during classroom interaction.
