In the utterly amateur teaching I have done the key thing, which someone will never get from a computer, has always, always, always been convincing the student that they are smart and that they can learn this stuff or indeed anything. Next most important is generic how to learn stuff, which for the people I have taught usually starts with relaxation exercises and other techniques to overcome their fight or flight reactions to get to a place of relaxed enjoyment.

I don't know how that replicates to other, better, more experienced teachers observations of it. If it is as important as I think, I don't know how you get that from a computer.

Learning and study abilities are tortured and murdered by the constant re-enforcement of "you can't, you're not smart enough, them over there, they are better."

Maybe I'm over emphasising a point that is less important than I think but also maybe not. It's a point that needs an airing here either way. Interested in your thoughts, especially if you have experience.
