In this paper, we present a study conducted to evaluate instructional support measures for a net-based collaborative picture-sorting task. A combination of a model collaboration presented as an on-screen video to the collaborators prior to collaboration and a collaboration script was developed to support individual cognitive as well as collaborative demands. In a 2×3 factorial design we varied the amount of support as well as the mode of communication in order to test the impact of the support on the collaboration process and performance in net-based interactive and non-interactive communication settings. The results showed an improved collaboration process in conditions with support but no significant effect on the performance measures. The support measures fostered the collaboration process even in the particularly difficult conditions with non-interactive communication.
