The paper uses the Praxis approach which means action with reflection. Simulations are mechanisms to allow for a cost effective and practical approach to set up learning opportunities where the learner can actually learn by doing. Case-based reasoning situations is suggested because the learner works through a problem. Traditional programs detach motivation from fact. The component of interaction is identified as being important.
Humans are social in nature.
We need interaction to challenge our beliefs and understanding. Learning requires us to move into unfamiliar, often uncomfortable domains. Interaction can make up for a lack of self-direction. Instructors should transfer control back to the learner and raise the demands made on the learner. The instructor should be less authoritative and more a sympathetic coach.
