Well, I don't think that's the only problem with education.

Scaling good teaching, huh. Tackling this with direct technology is difficult, things like message boards for teachers are a bit crude.

So perhaps another way of approaching it is better training and support for teachers - and this is where tech can be used as support. Example, shadow a well-respected teacher with a camera, and post regularly on YouTube while encouraging open discussion.

Actually there is a lot of this content already (check out "Blended Learning" on Coursera, for example) so perhaps the real problem is actually aggregation and distribution.
