The article presents the successful experience of teaching the basic International Business (IB) undergraduate class, in an interactive way and in classes of more than 200 students. The approach follows modified routines taught in AACSB workshops for much smaller audiences and capitalizes on 5-member student teams. The format has been used for three years in a row and has produced extremely good results, including significant class interest, very high outcome assessments, annual CD-ROMs on a variety of topics, a very active student association, student-organized conferences, a career center, student-to-business interaction and undertaking of social causes.
