Instructional measures were designed to foster collaboration in a net-based problem-solving task. They include support for communication and for the individual and collaborative problem-solving process. A "worked-out example" of collaboration realized as an on-screen video was combined with elements of cooperation scripts. In a 2x3 factorial design, the type of support and the type of communication were varied. Audio recordings and performance measures were taken. As first steps of the data analysis, the performance measures of 24 dyads were analyzed and two in-depth case studies were conducted in order to compare the collaboration with and without the support of the developed measures. The collaborators with instructional support made fewer communication errors, managed to better structure the collaborative problem-solving process, and solved the task faster --- they appear to have learned to collaborate. Further quantitative analyses of the whole sample of 48 dyads are work in progress.
