Although the members’ categories associated with institutional settings may seem obvious, more can be said about the actions that make them noticeable and persistent across contexts. This study investigates how epistemic stance displays make the standardized relational pair ‘teacher–student’ relevant during writing conferences in a US university. Analysis of the interaction between teachers and their students shows that teachers tended to display more knowledgeable stances concerning writing and institutional practices, whereas students displayed knowledgeable stances with respect to their own papers, (...) indexing the immediate relevance of the ‘teacher–student’ relational pair and a tension between authority and autonomy. Further analysis reveals that participants also mentioned past and future writing activities, thus indexing the persistence of the ‘teacher–student’ pair as well as the emergence of the category ‘autonomous writer’. Additionally, participants’ orientation to the more general ‘writer–reader’ pair also functioned to index the persistent and emergent aspects of these categories. (shrink)
