The organization of collaborative math problem solving activities across dual interaction spaces

Zemel, Alan
Stahl, Gerry
In this paper we focus on the organization of activities that produce shared graphical representations on the whiteboard of a CSCL system with dual interaction spaces called VMT Chat, and the ways these representations are used in conjunction with chat postings as semiotic resources by interactants as they jointly make sense of and build upon each other's mathematical statements. Keywords: Dual interaction spaces, interaction analysis, shared representations
