Learning to work effectively in multidisciplinary teams is one of the skills identified as a primary learning objectives for the Interprofessional Projects (IPRO) program at Illinois Institute of Technology. There is little consensus about the best ways to develop teamwork skills, particularly among undergraduate students teams. We have adapted a set of "IPRO Olympics" games designed to emphasize teamwork and group communication We have 34-40 teams who have completed a Team Excellence and Trust Survey at week 5 and at the end of the semester, as well as multiple measures of team functioning, with data over two semesters. We have found that teams who had at least one participant in the IPRO games were not significantly more likely to feel that their team was functioning well at week 5. However, "participating" teams were more likely to submit good initial project plans, submit good meeting minutes, be evaluated more positively in their IPRO Presentation and Exhibit performances, and generally receive more positive evaluations from judges evaluating their projects.
