Emily Messner:

The students swapped stories of little sisters, brothers and cousins who were taking above-grade-level math and getting good grades, yet did not seem to have a firm grasp of the material. The curriculum is being “narrowed and shallowed,” Walstein said. “The philosophy is that they squeeze you out the top like a tube of toothpaste. That’s what Montgomery County math is.”
Several students nodded their heads. This thesis has become Walstein’s obsession: In its drive to be the best, please affluent parents and close the achievement gap on standardized tests, the county is accelerating too many students in math, at the expense of the curriculum — and the students. The average accelerated math student “thinks he’s fine. His parents think he’s fine. The school system says he’s fine. But he’s not fine!” Walstein declares on one occasion. On another, Walstein is even less diplomatic. ” ‘We have the best courses and there’s no achievement gap and everything is wonderful,’ ” he says, parroting the message he believes county administrators are trying to project.
“The problem is, they’re lying!”
