Traditionally, class periods have meant that students listen to a professor lecture for about an hour. Cooperative learning can replace some of that lecture time with methods designed to get students actively involved during the class period. In this article, I highlight some methods of cooperative learning and suggest ways of integrating it into simulation study. Detailed examples are given on cooperative learning in a simulation course where GPSS/H is used for simulation modeling. Student feedback and results using the new methods are briefly discussed.
