More on teacher metrics
Carl Bialik, the Numbers Guy for the Wall Street Journal, talks about the effectiveness of teacher metrics this week. It’s a pretty good rundown of the risks of applying such a system, including:
- Incentives to teach to the test.
- Incentives to cheat outright.
- Disincentives to go into teaching if the system is seen as unfair by teachers.
- Problems with measurement resulting from classroom assignments.
I’d consider this piece mandatory reading if you read the LA Times piece about teacher evaluation.
