What if we find out years from now that whatever we are doing is simply wrong?
Why are we doing so many things now in education that have no evidence to support them?
If this were medicine instead of education, would anyone tolerate the experimentation that is being done to the entire population?
I actually think we know more than the article suggests.
For example, there is no evidence to support merit pay.
There is very little evidence to support the use of student test scores to measure teacher quality, and what little there is in conflict.
There is a growing body of evidence that says that online schools produce poor results for K through 12 students.
But the point is important: Our policymakers are plunging full steam ahead into uncharted waters and putting the lives of millions of children–and our society–at risk.
