This article compares the sequential position, action, and design of teasing sequences in classroom and mundane interaction. This collection of teases comes from a university Geosciences classroom, and the analysis demonstrates that, like teases in ordinary conversation, classroom teases are sequentially bound and designed in extreme fashions. Nonetheless, classroom teasing sequences are unique in terms of the actions and precise designs of teasables and teases as well as the sequential contingencies that create opportunities for teasing. This paper contributes to past (...) conversation analysis research showing how teases as sequences of embodied action are subject to local contingencies and constraints. (shrink)
