Online Speech Class: Um...How??

Speech, debates, and public speaking. These have all been perfected overtime in front of peers, co workers, fellow students, and colleagues. I ask, how could we offer a public speaking class online? Does this not defeat the purpose of getting over one of America's worst fear? Simply speaking in front of a large group. Believe it or not, many esablished college's are currently offering online speech classes where you simply record your speech, and send it in for grading. Can you think of at least 2 ways in which this could lead to false grades, and no courage gained?
