From Luis Villa's post on wiki usage in law school classes:

In my experience, and if done well, can also teach collaboration, editing, and other writing skills. There is still a lot to learn about the ‘done well’ part, but I hope Prof. Goldman and others continue to experiment with it. They’re doing the right thing even if their students don’t realize it yet :)

Worth reading. Also worth reading for engineering students frustrated and befuddled by those annoying "contract" things: what writing a contract feels like, explained in coding metaphors (analogy actually from Alex Macgillivray, but following Luis's blog is what led me there):

"To put it in computer terms, imagine the contract as a computer program. In each the object is to be able to interpret the words and have that interpretation drive a result. Now imagine that there is no compiler for your program and that you can’t run any tests. All debugging must be done only theoretically and in your head."
