I'm torn. I think what she says may be true for the middle 50% of kids, and any change that helps half of all kids is worth taking seriously. The problem is that it's somewhat untrue for everyone outside the middle, and harmful to the group on this board.
There needs to be a greater acceptance that it is ok for kids to be different. My kids' love for math really shouldn't feel like a threat, any more than your kid's soccer ability is a threat, and it's just as wrong to coach them the same in math as it would be in soccer.
