Universities increasingly incorporate multidisciplinary design projects into their curriculum to better prepare their students for the labor market. In these projects, student team members of various disciplinary backgrounds develop new product or service concepts for organizational partners. This structure enables students to learn not only from the interaction with the content and lecturer, but also from communication with other team members. Little is known, however, about the relative effectiveness of specific communication modes on improving student learning outcomes in these interactions. This study examines the effect of three important communication modes--metaphors, visualizations, and narratives--on reported learning from other members. A total of 64 students working on two large multidisciplinary design student teams participated in this study. Survey results indicate that perceived learning increases through awareness and use of metaphorical communication, beyond previously supported effects for narratives and visualization. We conclude with implications for the way information is represented and structured within multidisciplinary design student teams, and future research directions.
