In the end, [Diane Ravitch's] Death and Life is painfully short on non-curricular ideas that might actually improve education for those who need it most. The last few pages contain nothing but generalities: ... "Teachers must be well educated and know their subjects." That's all on page 238. The complete lack of engagement with how to do these things is striking.
If only there were a system of institutions where teachers could go for instruction in their fields. If there were such a system then Dr. Ravitch could say "Teachers must be well educated and know their subjects" and all reasonable people would assume that she meant we should require teachers to take more advanced courses and provide additional compensation for those who exceeded those requirements.
