Talking it through
When Stephen Hawking lost the ability to speak in 1985 he realised with great frustration that he could no longer talk through a problem with others and in so doing clarify his thoughts.
For a student to be able to talk through a subject with tutors and fellow students is a vital component of learning that risks being absent where e-Learning is supposed to provide all of that. Face to face in tutorials and at other events, such as in a debate or subject-some specific society is ideal. The next best thing is having formal a Google hang-out and other interactions that are live (synchronous) as well as asynchronous.
