Collaboration and Chat: Recipiency in Online Math Problem Solving

In this paper, we examine ways that participants in online math problemsolving chat sessions dis-attend and attend to postings by other participants and the ways that participants design their postings to elicit responses from recipients. This is consequential in terms of the design of CSCL systems that use chat as the basis of participant interaction. By developing a proper understanding of the affordances of chat systems and the structural constraints they place on the moral organization of interaction, we can begin to anticipate and address issues related to the achievement of collaboration.
