University of Duisburg, Germany Learning and (System Dynamics) Modeling Tendency: Interactive tools for modeling & simulation Learning by building and/or using models How to design learning scenarios, especially for learning in groups, that deal with modeling? July 2002 Palermo, Italy Niels Pinkwart University of Duisburg, Germany

University of Duisburg, Germany Opportunities for collaborative modeling Share a running model Share the model building process Cooperate while reflecting about the envisaged model Build groups having different data and analyse results Supervision by sharing models with tutors ( MFL “Model Facilitated Learning”) July 2002 Palermo, Italy Niels Pinkwart University of Duisburg, Germany
