Then today, via GothamSchools, I picked up this delightful blog posting that also uses sports metaphors to get the point across. Most sensibly, this blogger, Sam Chaltain (with whom I was unfamiliar before but is becoming a very fast favorite!) points out that while there are certainly superstar teachers and teachers who might nicely be described as not-very-superstar-like, the vast majority lie somewhere in between on the competence and effectiveness scale. These teachers, he argues, need investment and support, not scorched-earth policies that force them to narrow their curricula, pedagogy, and (I think) their own spirits, interests, values, and talents in the classroom to what Chaltain calls "40 times"--reading and math test scores.
I don't know why I think people like Klein and Bloomberg will listen to Chaltain any more than they'll listen to me, but I would like to encourage him to keep talking.
