Chris,

I have combined my comments with Scott's.

I don't think it sounds too ambitious. Nobody has any real data on how
technology as we are looking at it influences education. Our point is to
provide a test-bed to discover those answers.

The second sentence in the Electronic Chalkboards paragraph has a repeated "a
a" that should be removed.

More than that. We need to stress that student dorm rooms will be
internet-connected. We have a lot of the infrastructure for wired
communication.

Good point. I'm finding that it's extremely easy for me to point a student to
Web pages for previous versions of classes I have taught to answer questions
about what goes on during them. The more information we capture about a
class, the more it can be used as a replacement. But of course, Chris has
already bemoaned the fate of video courses, so I don't know that this is a
point we should push too much. Our objective is not to eliminate the need for
classes, but to make them more effective.

Not really. If you are recording all of this information, then it's natural
to ask about what you do with it. It's the basis for the working on better
student assistants. How about Personal Educational Assistant rather than
Tutor?

Good job on this, Chris!
