Collaboration in digital ecosystems can be very complex due to varying types and possibly large numbers of actors and artifacts, and the many possible interactions between these entities. Hereby, network visualizations can be helpful for supporting cognitive processes, like fostering reflection, enabling awareness in students’ learning, or for visually analyzing networked collaboration. In this paper, we examine different techniques of visualizing ICT-enabled interactions in learner networks. After giving a brief overview of related work, we argue for the application of two-mode networks for visualizing patterns of networked collaboration in digital ecosystems and discuss different issues by comparing this technique to traditional visualizations.
