Beware of Arne Duncan's Tricks
The statistical evidence is that smaller class size means better education, but smaller class size also means higher taxes. So Education Secretary Arne Duncan chose trickery to divert parents from the clear road.
At a recent meeting of governors in Washington he suggested that they pay bonuses to the best teachers if they agree to increase their class size. Duncan would prefer to put his own school-age children in a classroom with 28 students led by a “fantastic teacher” rather than in one with 23 and a “mediocre” teacher, he said.
But what parent wouldn’t? If large class size becomes the sign of a good teacher, no doubt all parents will insist that their child be placed in the largest class that a school has to offer. Unable to fit all students in just one class, however, principals will declare all teachers fantastic and assign large classes to all.
And the beauty of it is that the demand for large classes will come from the parents themselves. Clever, huh?
