<p>Maybe it’s already been mentioned above, but K-12 textbooks must closely match a multitude of (annually?) changing state learning standards, so textbook publishers cram as many standards-matched elements into a page as possible. Without those elements matched to standards, which then will be tested/assessed for learning outcomes by BOEs, and through which funds will be disbursed and teaching careers will be sanctioned, the texts will not be purchased by the districts. No match, no buy. Think Common Core. Sadly, this process has led to Frankenstein textbooks as publishers chase the sell while also, strangely, slashing staff writers, editors, and others involved with quality control. It’s ridiculous. </p>
