Employers want students who are able to work effectively as members of a team, and expect universities to develop this ability in their graduates. This paper proposes a framework for a collaborative writing assignment that specifically develops students' ability to work in teams. The framework has been tested using two iterations of an action research project, with this paper focusing on the second iteration. The paper provides detailed information on how the framework was implemented, and then reports on the students' perceptions of their learning about teamwork.
