The tablet medium also seems ideal for simulated cases, says Glenn Rowe, a professor at the Ivey school and author of nearly 40 case studies. In role-playing exercises, prices and other variables can change on the fly. Students may also be smacked with unexpected events, such as their biggest competitor slashing prices, or by their receiving a higher-than-expected counterbid after a merger proposal. Students choose what they would do, and the simulation immediately tells them the consequence of that action.
