A simulation is a way for an individual to experience an action or concept in a pretend situation without actually having to take the same risks that may be involved with the actual activity. Because of the lack of risk we are free to explore the subject matter and glean experience from it. In an educational setting it also helps teachers provide students with access to experiences that might be otherwise impossible to gain. As a supplement to the class they provide real learning experiences.
An example of a simulation that does not use technology role play the people involved in a history lesson and make it more real for them. An example of a simulation that uses technology is a high school drivers ed class that uses a computer cars simulator to have students experience the controls of a car without having to be in one.

Shellmans article is about using simulations to teach alternative forms of government. Though the article focuses specifically on the German form of Parliament I felt that the article did a good job of establishing why the simulation was a good idea and how you would use it. It seems that you could easily shift the simulation to something other than government and still be effective.
Simulations are great because they allow a great deal of experimentation that is not available in other forms of teaching. They also help make connections between what is being taught and the real world. Simulations are very constructivist in nature and thus allow a better connection between the learner and the content of instruction. Simulations also allow students to learn from different angles or in different ways perhaps utilizing multiple intelligences.
