Simulation games are one popular type of TDI. They refer to instruction delivered
via personal computer that immerses trainees in a decision-making exercise in an artificial environment to learn the consequences of their decisions. The games are intrinsically motivating, and some people report that they actually lose track of time when
playing their favorite ones. When used for training, they seem to pay off quite well.
Meta-analysis results indicate that relative to a comparison group, post-training self-
efficacy (belief that one can succeed) was 20% higher, knowledge of facts was 11%
higher, skill-based knowledge was 14% higher, and retention was 9% higher for train-
ees taught with simulation games (Sitzmann, 2011).
