Perhaps more challenging than the software was the difficulty adapting an environment designed for a single person to work in groups. There were only four functional workstations available to be shared by twenty four students. Due to time constraints, this meant that groups of at least two, and often up to four, students would work together with a single computer (Figure 1). This issue has been addressed in recent studies [7,13] using specially designed systems which support multiple user control of a single pointer. In the IPS context, users were left to negotiate use of the resources and develop their own solutions.
