Another big hoax: National board certified teachers

Today's Columbus Dispatch reports on the number of national certified teachers in area schools.

First off: There is no evidence that certified teachers are any better than the run-of-the-mill teacher. And, there is much evidence that these teachers actually produce lower results as the national board certifies teacher knowledge and qualification in pedagogies that are ineffective at best.

Secondly: To produce a students per certified teacher stat is absurd. Oh, it's interesting for discussions and debates, but it has no meaning. Assuming -- falsely -- that nationally certified teachers produce better results, what in the world does the per pupil statistic matter if your child is not in a classroom with such a teacher?

The average is not some ether that permeates a school. Some people, and some reporters, do not know when it is appropriate to use average, and when its not.

Some may feel squeamish about eating it, but rabbit has a fan base that grows as cooks discover how easy they are to raise — and how good the meat tastes.
