COMPS is a web-delivered computer-mediated problem solving environment for student collaborative exploratory learning. The primary mode of interaction is typed dialogue, but COMPS also provides problem-specific affordances for exploring a problem. This paper reports qualitatively on dialogues from students employed in four different activities: two logical reasoning problems in a quantitative l...

In this chapter we present a thread-based approach for analyzing synchronous collaborative math problem-solving activities. Threading information is shown to be an important resource for analyzing collaborative activities, especially for conducting sequential analysis of interaction among participants of a small group. We propose a computational model based on thread information, which allows u...

On the basis of an experimental study, we propose a cognitive simulation model of collaborative problem solving and learning. In the experimental study, we investigated how qualitative and quantitative problem representations in classical mechanics are acquired and successively interrelated during collaborative problem solving. Two students, who were taught different aspects of classical mechan...
