It is pointed out that preparing people to work collaboratively allows them to experience some issues of professional ethics, cooperation, responsibility, and decisionmaking. A model for teaching people to work collaboratively is described. A teaching team, comprised of a technical communication professor and a clinical psychologist, explains group dynamics and the three phases of group development to students. The team then asks the members of a group to rehearse roles and discuss various issues that may arise in their groups. It is concluded that people experience and work through issues of collaboration and professional ethics before they begin to work as a group.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
