This study argues that the shift towards a more multidisciplinary professional life in contemporary design practice requires design curricula to equip students with collaborative skills. The study offers that by the aid of web-based collaborative learning (WBCL) in design education, different disciplines may be brought together during their education. A case study is held as a rehearsal of professional life; involving architecture and interior architecture students collaborating on a common project, using WBCL. The evaluations of the participating students about the process were analyzed. The findings convey that there is a mutual problem of recognition of professional domains. In order to diagnose and possibly reconcile tensions that may occur due to this problem in professional life, this paper asserts that integrating interdisciplinary work to the design curricula would be beneficial.
