These days it seems like every politician and pundit has a strong opinion about how to improve the teaching profession. But, in a piece for Time, Andrew J. Rotherham points to some recent research to show that we’re actually a long way off from easy or one-size-fits-all solutions:
[T]he reality is that because of years of inattention to teacher effectiveness, we still know relatively little about what makes a teacher great and how to build systems full of great teachers and high quality instruction. That frustrates policymakers -- and it should terrify parents. But it's also an enormous opportunity for a field that is ostensibly about learning to perhaps learn something itself.
