@inproceedings { prada02, abstract = {In this paper we discuss how collaboration issues are addressed in the context of Teatrix, a virtual environment aiming at providing the children with the means for collaboratively creating a story on a virtual stage. The children create stories using a set of pre-defined scenes and dramatis personae — characters that have specific roles in the play, which they control to a certain extent). Each child expects the story to evolve in reaction to her/his character’s actions and the overall story emerges from the collaboration of different children. Based on this premise we conducted some evaluation experiences, in order to assess to what extent Teatrix promoted collaboration and what types of collaboration were particularly elicited by the application.}, address = {Biarritz, France}, booktitle = {ITS'2002 - 6th International Conference on Intelligent Tutoring Systems}, keywords = {narrative, storytelling, learning virtual environment}, month = {June}, pages = {913-922}, publisher = {Springer Berlin / Heidelberg}, series = {Lecture Notes in Computer Science}, title = {You cannot use my broom!
