This paper discusses business games as teaching tools in Management Science (MS). The discipline's traditional teaching methods, while appropriate for the dissemination of foundational knowledge, cannot provide students with a platform to link abstract concepts and real-world problems. We suggest that business simulation games are an effective way to engage students in MS topics; that they compel students to understand and cope with the ambiguities associated with real-world organizations. Specifically, we discuss our experience with the International Operations Simulation Mark/2000 (INTOPIA), a game designed to channel students into a stream of entrepreneurial decision-making. We employed the game over 12 semesters with approximately 1000 advanced MBA candidates. Our findings indicate that business games represent a novel instructional approach: this pedagogy has a real potential to promote the exchange of new ideas on teaching and learning within and across courses in the MS discipline.Editor's note: This is a pdf copy of an html document which resides at http://ite.pubs.informs.org/Vo8No1/ Ben-ZviCarton/ (Volume 8, Number 1, September 2007)
