Resumen
A major limitation in traditional class lectures on simulation and modeling, that uses assignments, handouts, transparencies, and textbooks, is that students often are unable to appreciate the "experience" of simulating a real problem. This limitation can be overcome by using an active real case study approach to allow students to simulate a real-time queuing problem through interactive visual simulation software (EXTEND). Actual raw data had been collected prior to the case assignment and students are taught to develop the simulation model, based on the actual raw data. The intent is that by "doing" or "constructing" the simulation model from actual data, the students will understand better and remember.
