In the spring 2007 semester, the instructor taught one international relations class of

twelve students, which participated in the simulation. The mean scores on the second and third

exams were 76.4 and 68.5, respectively.

In the fall 2007 semester, two classes experienced the simulation and one did not. The

mean score of the third exam was 1.4 points lower than that of the second exam for simulation

participants. The mean score of the third exam was 4.9 points higher than that of the second

exam for students who did not participate in the simulation. The mean score of the third exam

for simulation participants was 4.5 points lower than that for students who did not participate in

the simulation.

Figure 2: Exam Scores for Fall 2007 Semester

When data for the fall 2006, spring 2007, and fall 2007 semesters are aggregated,

simulation participants scored slightly higher on the third exam then they did on the second

exam, with a change in mean scores of 0.6 points. A similar effect occurred among students who

did not participate in the simulation – the change in mean scores was 0.5 points. Simulation
