Major technical problems
-
Unreliable and Varying Quality of browser (Netscape) and link (internet/DREN)
|
Several obvious technology improvements
-
full database backend; use two-way video on reliable link; interactive annotatable lecture material; record audio-video conferencing, annotations, chat rooms for asynchronous replay; better link of asynchronous and synchronous tools
|
Most interesting is new modes with graduate assistant manning ancillary tools such as chat rooms to enhance richness of interactive sessions
-
Professors cannot easily lecture and monitor other tools at the same time.
