Group Learning Histories for WikisKeywords: Group adaptivity , learning history , E-Learning , Wiki Abstract: Wikis are an important part of collaboration in E-Learning, as they allow easy modification mate-rial of other contributors and integrate multimedia elements. Versioning of changes is built-in, but this refers to individual actions of one person only. Especially in E-Learning both aspects can be problematic, as not individual changes but larger activities are needed for a personal learning history, and because of group work an aggregated history of several persons is desirable as well. This paper presents the basics for deriving group histories of activities from individual actions and presents an exemplary implementation of this in a Wiki within a learning environment.
