I met a 10 year old child with Asperger's[1] who was trying to do some math homework. The book was wrong; they hadn't labelled a diagram but were asking for those labels in the answers.
Maybe some children would have worked out to create their own key or to write in the book, but this boy just stopped. An activity that he's good[2] at, that he enjoys, is being slowly poisoned by poor quality materials.
It's not just math books either. Where's the Feynman quote about the horse evolution?
[1] Proper diagnosis from a set of real doctors.
[2] Got a scholarship to a decent school partly based on his math ability.
I'm not sure that a kid with Asperger's stopping when they encounter a problem leads to the conclusion that "[math] is being slowly poisoned by poor quality materials."
