This paper presents a collaborative team learning model for integrating student learning in a graduate IS course and a graduate HCI course. Through coordinated project schedules of partnering teams, an emphasis on social interaction, and the use of collaborative technologies, students expanded their experience in developing Internet commerce Web sites. For the HCI teams, they learned realistic consulting experience. For the IS teams, HCI support led to high quality Web site prototypes. This paper reviews the motivation, approaches, evaluation methods, findings, and implications of this innovative teaching method.
