Webcasts, I still understand.... when I was a freshman quite a
few of my core modules were webcasted. I ended up skipping lectures
to watch webcasts instead.
After all, you can always rewind the video if you didn't catch
what the lecturer said, or pause if you feel like going to the
kitchen to make a kopi..... 
But the lecturer for my Monday night class seemed to think that
live lecturing via chat rooms would be better....
But really, with the IVLE chat room, you can't see what the heck
the lecturer's referring to, and his voice sounds as though he's
broadcasting via walkie talkie....
I haven't seen the e-learning stuff yet...so I have no idea
what's in store for me.
I haven't attended a single economics lecture and I only used
the webcast once because I simply couldn't understand the
slides.
Chatroom lecturing is so restrictive compared to the
webcasts.....but at least one module of mine offered both.
Last week went to school for lectures....this week for
tutorials. $%^$#
