Abstract
This paper describes the iterative design of a web-based collaborative workspace used in
educational practice, called WebReports. The system’s unique feature is that it allows participants to
discuss mathematical and scientific concepts using programmed animated and interactive models of their
ideas. Rather than focusing on the specific features of the collaboration tool, we analyze it as part of a
constructionist activity system. We describe the context in which the system was developed and used and
compare our approach to previous research in the field. Further, we then present two scenarios which
demonstrate the system in action. Following that, we attempt to map our cases to an activity theory
framework. We highlight several issues in the process of the systems’ development, where the contradictions between the WebReports system and other elements in the activity system shaped its design, and comment on several issues which go beyond the activity theory framework.
