Enriching accounts of collaboration by using video

This paper will discuss the approach to the evaluation of computer-supported collaborative learning developed in our group over the past ten years. This approach depends on the collection of video data to allow the analysis of key features of problem solving behaviour within groups of students working on collaborative learning tasks. Our theoretical framework derives from two sources- the CIAOl framework for evaluating examples of CAL and an analysis of appropriate methods of evaluating computer supported collaboration.
