Exactly. Burning most textbooks published in the last 50 years or so is doing a service to education.
You do need updates in science and history, but the best textbooks are from the early to mid 1800s.
Read, "Why Johnnie Can't Read", by Rudolph Flesch, from the 1950's or so.
Then read his sequel, from the 1970s or so, "Why Johnnie STILL Can't Read".
When administrators try to eliminate books, they need to be sure that students truly have access to their instructional materials at home. That's not always so simple if they don't have the right technology available at home, or if there is shared custody and one parent lacks technology. Kids today all seem to have cell phones, but many of them don't have printers, and laptop access can be spotty. Laptop carts in the classroom aren't enough, especially in an AP class. There aren't enough classroom hours to cover the content and students need to do a lot of work at home. Perhaps these teachers have the kids do their labs at home and read at school . . .
