Lars Bollen studied Physics and Computer Science for Higher Education at the University Duisburg-Essen in Germany. He graduated (“Staatsexamen”, MSc. equivalent) in 2002 about the integration of visual modeling languages into the learning environment Cool Modes. After graduation, he joined the Collide research group, lead by Prof. Dr. Hoppe, in the Department of Computational and Cognitive Sciences at the University Duisburg-Essen.

Lars Bollen worked on projects like eCampus, COLDEX, SkyWatch, Argunaut and participated in various activities within the NoE – Kaleidoscope.

In 2009, he finished his PhD at the University Duisburg-Essen on the topic “Activity Structuring and Activity Monitoring in Heterogeneous Learning Scenarios with Mobile Devices”.

In 2008, Lars Bollen joined the Department of Instructional Technology and worked on the 7th framework project SCY, on the TWID project (“Thinking with Inaccurate Drawings”), on the Kennisnet project “Samenwerkend computerondersteund tekenen in het basisonderwijs” (“collaborative drawings in primary school education”) and on the FES project “Learning through modeling and self explanations”.
