This paper proposes a research agenda for a relatively new area of research in information systems: wikis in collaborative writing. We introduce wikis and the concept of collaborative writing using four different educational cases of wiki-usage for collaborative writing in the classroom setting. Eight research questions are suggested related to this area of research. We propose that Adaptive Structuration Theory (AST) is a useful theoretical framework to study these questions. The paper suggests the importance of this new area of research through four case studies and identifying research questions that need to be addressed using the AST framework and suggesting implications for educational practice.
