The Language and Social Interaction Working Group (LANSI)

Welcome to LANSI!

Sponsored by the Vice Provost's Office and the Applied Linguistics and TESOL Program at Teachers College, Columbia University, LANSI  brings together like-minded colleagues in the larger metropolitan area of New York who work with audio/video-recorded data from naturally occurring interaction. Through our regularly held data sessions, LANSI offers a forum in which participants continue to build their analytical repertoire via mutual engagement over time. In so doing, we also experiment with an apprenticeship model where graduate students work alongside practicing analysts making observations and providing accounts for those observations "empirically and precisely" (Schegloff, 1996, p. 167). For more information about LANSI, please contact us at You can also follow us on Twitter @lansi_tc.
