What uses can Virtual Learning Environments be put to when blended with traditional courses?

VLEs can complement and supplement amended traditional courses in the following ways:
VLEs Allow students to
Recap on what has been taught and supposedly learned;
Delve further into a topic of interest;
Review with others so as to improve learning and performance in tests;
Have teacher develop and have materials available on the VLE for own use in class;
Discuss particular topics in a closed forum, guided by a teacher or student facilitator;
Scribe of the day approaches to notes.
Catch up on missed lessons or coursework.
Collaborate on and publish work online.
Take a machine marked test to be used formatively by the student.

Additionally, by producing VLE courses which students take in their own time, they experience self-directed learning by the type of learning or training medium which they will experience at university and at work.
