Just watched DVD of educational changes announced by Ed Balls. Look at the black guy at the end. Whatever he is achieving could be improved upon. Obvious developmental delay. Poor lad cannot hold a pen correctly - note pressure applied , see knuckles. Too close to paper- developmental problems. If we addressed such issues across population we would see improvements in individual performance, less adverse behaviours, more contented children. Such programmes exist and research has been paid for by education bodies. Why do we not use what is known? We can put in individual reading programmes but it reaches only a very few and is expensive. We could get the same improvement for a much larger number by early developmental intervention.
