Chaplainintraining,
In the preaching class at SBTS, we had to preach once in front of the class and twice outside of the class, and video each sermon. After that we had a written review from each classmate and from the professor evaluating (in real-time & then again written later) our takeoff & landing, content, exegesis, exposition, transitions, application, etc. We then wrote our own analysis & critique of the sermons, as well as listening to a required set of sermons that semester in chapel & discussing them in class w/ the professors (we had 2 profs teaching our class together). Of course there were the lectures & books & papers too. Lots of interaction; still wish it had been under the direct oversight of my pastor at the time.
I agree with you -- I imagine that a distance/online option would involve video, and I suppose the prof could give you a written evaluation, and maybe if the videos were posted on a site then you could review the other guys & they could review you. Still not sure that it would be ideal though. It's not the same. Not that it would be unprofitable; just don't think it would be best. But if it's a man's only option, and it could be studied under the close oversight of the elders of his church, then it would probably work out pretty well.
Just my $0.02.
