Hi Scott: Often the question will be "what is the best presentation method?". After clear objectives are defined then we need to look at what resources are needed and what resources are available. Unfortunately, sometimes we have to work with less than what's needed whether that be human, physical, or technolical resorces. Tools are extremely helpful, yet even with the best presentation resources, if the students are not getting the message we've missed the point as educators. Regards, Barry Westling
