Valuing physics over P.E., Colorado schools test novel pay scale

As a math teacher, I was always (selfishly) interested in teacher pay scales that valued hard-to-fill positions more. I think the current model for paying teachers, one based on experience and credits earned, is unfair. (I've touched on this before at http://blog.mathed.net/2010/03/taking-salary-schedule-beyond-two.html.) The thing is, I'm not sure most merit pay models are any more fair, and I'd rather work in a system with an unfair system that teachers agree with than an unfair system they hate. Douglas County, Colorado, will be experimenting with a market-based approach to paying teachers, and some teachers don't sound happy about it.
