This presentation reports the findings of a study designed to investigate the collaborative writing and revision processes of foreign language learners in a wiki environment. Specifically, it is based on a comparison of two wiki projects in intermediate German classes in which small groups of students used wikis to collaborate on a project based on cultural and historical topics related to a novel. The archived versions of the wiki were analyzed for the amount, type, and quality of revisions. In addition, an end-of-semester survey was administered to assess learner attitudes towards the project and perceptions of the writing process.
