Roshone:
I agree with students having access to a greater body of information derived from participation in asynchronous discussion forums. That is smuch more "dialogue" than what usually takes place in a traditional classroom setting. Moreover, students are likely to be more "open" especially when peer evaluations are done in an online environment.
In regards to online students being more serious and disciplined, I have not come across any empirical data to support that. I suspect that online students have a highler level of commitment, and are therefore more likely to devote the necessary eforts towards the completion of their online courses.
