Based on so-called "Classroom Games" students learn about decision making in different scenarios of strategic management. All scenarios are imbedded in a game theoretic framework in which Students have to make decisions under uncertainty. The teaching material is taught exclusively with experiments conducted by groups of students with their colleagues. Each group organizes an experiment, evaluates it and presents the results as part of a workshop. A written paper describes the economic theory, the derived theses, the experimental setup and the evaluation of the collected data. The course follows the intention to close the often observable cognitive dissonance of students who perceive real decision-making situations in real firms and the result of economic equilibrium models as different.
