Simulations are experiential learning opportunities during which participants can learn new information, as well as have the opportunity to apply previous knowledge. While hands-on learning has been incorporated into NRP and similar training for some time, simulation-based learning is increasingly being utilized in new and varied situations. This article begins with a general overview of simulation, along with a brief review of the historical background of mannequins and simulation. This is followed by several mini-articles describing how the authors have applied simulated-based activities to promote learning. The article concludes with a look at the potential future of simulation-based education.
