My CS proffesor used Dyknow last semester to teach a discrete class. In class he would use a tablet to write his notes which were then displayed trough a projector. The notes and sound were recorded in real time, then posted online so that students could download then listen and watch the lecture again.
This type of recording technology was great.
One thing I hate as a student is an over reliance on Blackboard. This application works okay for administrative tasks but really sucks as a teaching tool. Online discussion, quizes, and teaching material on this platform has always been slow, unreliable, and had little learning value for me.
