Supporting Online Collaborative Mathematical Exploration: Studying the Development of Collective Knowledge within Math-Towers

Math-Towers is a collaborative mathematics environment for pupils in grades 7 to 9. Using a fantasy adventure game context, students are presented with a mathematical challenge, given online tools for working on the problem, and provided with a messaging system by which they may exchange ideas and partial solutions. This paper presents the philosophy behind the design ofttlath-Towers and, using a complexity science framework, explores the extent to which it has been successful in meeting goals. The technical and social problems encountered and revisions made to address these are also described.
