I totally understand your point - I just worry about it from the perspective of the child - during the Q & A, one of the parents brought up the question of incentive ( he children were at present at the town hall - well, at least most of them )
I realize all children are different - mine are total opposites - DD13 is totally self-motivated - DS9 is on the low end of the spectrum, and he needs a little push sometimes to stay motivated, and definitely needs positive feedback.
My daughter, on the other hand, couldn't give a flying fig whether or not she receives positive feedback -
Again, I totally get what you are saying, but I heard a number of parents mumbling that if the tests are not being graded, they are just going to have their kids spend less time on them, and basically "wing it" - was a bit disheartening
