Free Medical Simulations
When we were looking at examples of learning theories, someone demo'd UF's own Virtual Anesthesia Machine. The team who developed that simulation (lead by Sem Lampotang) have developed many medical related simulations, several of which are available for free from thier website. Here's the url and link: http://vam.anest.ufl.edu/instructorsims/simulationportfolio.php
I recently went to a conference for medical librarians (more on the conference in my next post) and the use of medical simulations for learning was a hot topic.
