Debriefing is central to the experiential learning process, yet
simulation game research studies seldom have focused on it. Properly
designed simulation games with debriefing potentially provide a means to
engage students in thoughtful, engaging, and worthwhile learning that is
consistent with the contemporary goals of education. A small number of
prior studies found debriefing had a positive effect on cognitive
learning. However, the studies with positive results are too few and too
contradictory as a result of problematic designs to warrant
generalizations from the findings. The participants for this study were
238 students in state mandated economics classes. A variety of immediate
and retention posttest measures were utilized to assess the levels of
cognitive learning and interest on four randomly assigned alternative
treatments. Data were analyzed by means of descriptive statistics,
analysis of variance, and effect sizes. Findings from this sample
supported previous research results that indicated debriefing has a
positive immediate effect on cognitive learning. The implications of the
results and suggestions for future research were discussed in detail.
