%0 Journal Article %T ¡°BUT THIS IS WRITING¡±: POST-EXPANSION IN STUDENT-INITIATED SEQUENCES %A Christine M. JACKNICK %J Novitas-ROYAL %D 2011 %I Novitas-ROYAL %X Although conversation analysis (CA) began as a field focused on everyday talk-in-interaction, focus quickly extended to institutional talk (c.f., Drew & Heritage, 1992). Conversation-analytic research on classrooms has yielded an enormous base of knowledge about how the work of classrooms is done in and through language. Language classrooms have received a great deal of focus, with entire monographs dedicated to the subject (Markee, 2000; Seedhouse, 2004). Using conversation analysis to examine one type of sequence in classroom talk, this study focuses on the occurrence of post-expansion in student-initiated sequences. In these cases, the traditional three-part exchange is inverted; a student initiates a sequence, the teacher responds, and the student follows-up in the third turn in some way. In particular, both minimal and non-minimal post-expansions are examined not only in terms of their sequential placement, but also in terms of the interactional accomplishments of such turns. By detailing student use of post-expansion, this study demonstrates student use of power-moves in initiating sequences, role reversal, and student-created ¡°wiggle room¡± (Erickson, 2004) ¨C all of which suggest that the students are agents in their own learning. %K Conversation Analysis %K post-expansion %K student-initiated sequences %K agency %K IRE %U http://www.novitasroyal.org/Vol_5_1/jacknick.pdf
