IV. DISCUSSION
A common burden against the adoption of Virtual Worlds for continuing medical education is technical skills required by the trainee to use the software and “live” the virtual experience. On the other hand, a trainer has to spend more time to construct an electronic course even if the material is available for in-class traditional tutoring. Thus, both students and teachers have to “invest” some time prior to a virtual world event. This investment is faster depreciated compared to the costs incurred when participants of an event have to move to another town or country in order to attend.
