About 50% of Florida's lowest-performing schools are offering merit pay for teachers who help raise student scores. But bonus amounts vary by district, and some teachers say the bonuses say are too small to be used as incentives. Others think the merit pay should be applied to all educators, not just those who teach academic subjects. "I think it ups the morale of teachers," one physical-education teacher said. "Even though it's not really life-changing money, it gives you something you can look forward to."
