We review our research with "DEGREE" and analyse how our work has impacted the collaborative learning community since 2000. Our research is framed within the context of computer-based interaction analysis and the development of computer-supported collaborative learning (CSCL) tools. We identify some aspects of our work which have been followed up by other researchers and highlight some issues that remain pending. Finally we present a perspective of computer-based interaction analysis evolution in relation to a wider technological enhanced learning context.
