Abstract:In order to collaborate effectively in group discourse on a topic like mathematical patterns, group participants must organize their activities so that they have a shared understanding of the significance of their utterances, inscriptions and behaviors-adequate for sustaining productive interaction. The need for participants to coordinate their actions becomes particularly salient in dual-interaction environments, where, e.g., chat postings and graphical drawings must work together; analysts of such interactions must identify the subtle and complex ways in which meaning making proceeds. This paper considers the methodological requirements on analyzing interaction in dual-interaction environments by reviewing several exemplary CSCL studies. It reflects on the nature of social organization, grounding and indexicality that frame the interaction to be analyzed."Everything that can be counted does not necessarily count; everything that counts cannot necessarily be counted."

The Problem of Social Organization in Dual-Interaction Collaboration SpacesA central issue in the theory of collaborative learning is how students can solve problems, build knowledge, accomplish educational tasks and achieve other cognitive accomplishments together. How do they share ideas and talk about the same things? How do they know that they are talking about, thinking about, understanding and working on things in the same way? Within CSCL, this has been referred to as the problem of the "attempt to construct and maintain a shared conception of a problem" (Roschelle & Teasley, 1995), "building common ground" (Baker et al., 1999;Clark & Brennan, 1991) or "the practices of meaning making" (Koschmann, 2002). We have been interested in this issue for some time: (Stahl, 2006) documents a decade of background to the Virtual Math Teams (VMT) research reported here-chapter 10 (written in 2001) argued the need for a new approach and chapter 17 (written in 2002) proposed the current VMT project. During the past six years (see Stahl, 2009), we have been studying how students in a synchronous collaborative online environment organize their interaction so as to achieve intersubjectivity and shared cognitive accomplishments in the domain of school mathematics.Knowledge building in CSCL has traditionally been supported primarily with asynchronous technologies (Scardamalia & Bereiter, 1996). Within appropriate educational cultures, this can be effective for long-term development of ideas by learning communities. However, in small groups and in many classrooms, asynchronous media encourage exchange of individual opinions more than co-construction of progressive trains of joint thought. We have found informally that synchronous interaction can more effectively promote what we term "group cognition"-the accomplishment of "higher order" cognitive tasks through the coordination of contributions by individuals within the discourse of a small group.In CSCL settings, interaction is mediated by a computer environment.
