I like using Adobe Connect for virtual office hours, but I came across this blog posting at Elluminate.edublogs.org featuring how Dr. Ricky J Cox at Murray State used both a Tablet and Elluminate to teach / tutor chemistry. The video on the link is very instructive, at least to me who has used Adobe Connect. One thing is clear, in economics (as in chemistry) there are plenty of questions that can not be answered without resorting to the pen and drawing the graphs and equations of the answer. I was intirgued with the Illuminate product as explained by Dr. Cox and think it is a great tool for distance lerning.
In a separate post here are some examples of how Elluminate is used for virtual classrooms.
