Whatever Happened To Peer Review?

Peer review used to be a somewhat popular approach to addressing teacher quality issues (and a hope-inspiring example of union-management cooperation). And then it fall off the face of the earth (or seemed to). Now, Chicago -- of all places, where a reform-minded union leader was recently ousted and there is increasing talk of strike possibilities -- is trying to bring a version of it back in a small set of schools (Rookie teachers will be graded by a `coach' Chicago Tribune).
