Anyone else heard of it or have any experience of it? I heard the woman who started it talking on radio 2 the other day and it made me really irritated. They're charging a yearly subscription for access to the site, which currently only covers maths. It's got video clips on it, I think. The reason it irritated me though was that no one involved in setting it up has anything to do with education, and she kept saying something along the lines of "we know that the most important thing to make sure that children have a good education is access to good teachers" which, IMO is a bit of an over-simplification.
Anyway, it annoyed me, as a teacher, and I was interested in what other people think.
