The most insidious aspect of this likely debacle, is that the texts approved by Texas will likely be the ones used by other states (I presume for economic reasons). Obama has promoted the development and use of e-books in schools. This might ameliorate some of the costs of textbooks. It could also facilitate easier and less costly updating of textbooks. If the reactionary Republicans continue to control the government (and school boards) in Texas and want their children to be guided by 17th century ideas, at least this would not necessarily be imposed on other states.
With digital publishing, this problem should disappear within at most 10 years. School districts will be able to design and print their own textbooks. They can include or leave out any part they don’t like. The technology is available now, but it will take a while for school districts to get up to speed. I predict that each state will eventually have its own textbook printing and publishing facility, either state owned or contracted out. Or, even more likely, textbooks will be available on computers rather than as physical books. We’ve had enough of Texas creationist shenanigans. For once modern technology can trump stupidity and Neanderthal tactics. Let Texas be the creationist state.
