<< I think the first step would be to put together a professional committee
from AAPT members that could carefully scrutinize every new MS and HS
textbook with any physics in it. The reports would have to be published
openly with all errors exposed on a web site...>>
There are already processes for reviewing textbooks. There is even a
newsletter, with a highly competent set of contributers, devoted to this.
Also the "Physics Teacher" reviews physics texts, and other journals review
texts in their own areas. I lost the details in a hard drive crash but some
of the readers may know.
The state commissions and textbook manufacturers have always completely
ignored such feedback. Why would a new committee get different results?
