Simulations for Learning
Clark Aldrich is the author of a recent book, Simulations and the Future of Learning, in which he discusses how to leverage simulations as learning tools. In this Q&A article, he clears up some misconceptions about simulations (they needn't be complicated nor expensive!) and elaborates on their potential.
We're doing some work with simulations for a couple of clients of ours at the moment, so we find this stuff quite interesting.
