2) can be discounted probably, because students were chosen at random 1) and 3) seem a stretch. How do you teach to test in such a way ( assuming no cheating by teachers ), that kids can do math on the test, but later they lose that skill in such a way that they become worse (!) in a statistically significant way than those who weren't in pre-k ? |
