Back in the ‘90s the high school match books were derailed for indoctrination. There was a slant toward word problems so that the “educators” could embed liberal dogma in the text; e.g., since global warming is occurring, how fast will the ice melt.
Arizona wound up with math books which had been vetted in California. California is such a large market that publishers were paying attention to their desires. The books were so egregious that a local Arizona columnist, Marianne Jennings, railed against the curricula in the paper. Jennings had some standing as a Professor at ASU.
The chemistry book was so bad that my son’s instructor told the class she was going to teach out of her old notes (where there was actually some facts about chemistry).
That should read: “the high school math books”
