One of them talked about how parents should NOT be teaching their kids, or even so much as looking over their homework, when they're that age, because getting criticism from a teacher or coach is very different from getting it from a parent. From a parent, they interpret any negative feedback as, "You're not good enough, I don't love you," regardless of how kindly it's delivered, and how much positive feedback precedes it. From anyone else, it doesn't come across like that, because they're not so invested in getting approval from teachers as they are from their parents.
So I guess homeschooling would be out, then?
I agree that the idea sounds extreme. It's also lumping all smart kids together into the same personality, so I think that YMMV here. I teach my daughter (just 11) and taught my eldest son at that age. Neither one of them reacts like they've been devastated by my saying, "That one's wrong."
My daughter is even getting good at telling me, "Mom, the way you did that made things harder for me."
