1. Games and simulations can be effective learning tools when used appropriately. Avatars can model behaviors and influence learners' perceptions, especially when the learner takes the perspective of the avatar.
2. Simulations are most effective when embedded within a broader instructional program rather than used alone. Learners show greater confidence and retention when simulations include active, rather than passive, learning components.
3. Meta-analyses found simulations improved outcomes like confidence by 20%, and declarative and procedural knowledge by 11% and 14% respectively, compared to traditional instruction alone. However, simulations are not inherently better - their educational value depends on how they are designed and applied.
