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

In this paper, we focus on the organization of activities that produce graphical representations on the shared whiteboard of a CSCL system with dual interaction spaces called VMT Chat, and the ways those representations are used as interactional resources by small groups during their collaborative math problem solving work. In particular, we will investigate how actions performed in one medium inform the actions performed on the other, and how participants coordinate their moves across dual mediums to make their actions mutually intelligible to each other.
