Connected Modeling: Design and Analysis of the Modeling Commons

Modeling is not just a scientific activity, but an educational one, and is naturally paired with the theory and practice of constructionism. To date, however, constructionist modeling environments such as NetLogo have focused on individual work, rather than collaborative modeling. In this paper, we describe our research efforts at making modeling a collaborative activity, using a Web-based tool we have called the Modeling Commons. Using a combination of design research techniques, logfile analysis, and socialnetwork analysis, we have gained insights into the effective design of a collaborative modeling system, one which fosters the creation and growth of communities. Our logfile analysis indicates that social-learning theory, including legitimate peripheral participation, can be identified in such an online community. Finally, using social-network analysis, we are able to better understand the need for multiple channels of communication, in order to foster the creation of a fully connected community of modelers. We conclude by describing our future plans for the Modeling Commons, both as a software platform and as a tool for future research.
