Texas has always had a strong, centralized system for buying textbooks. Unfortunately, the Texans are continuing to dumb down and rewrite history and science. Next, we'll probably learn that Pi=3, because the Bible says it does.
Roger Ebert wrote an excellent piece on how bad this siutation has gotten:
Texas School Book Repository.
So I guess the question many of us have is - how can we convince publishers to publish fact-based science and history books? If Texans want to rewrite science and history based on the ravings of the lunatic fringe, shouldn't these books be self-published rather most lunatic fringe books are?
