I can only imagine what they are using in the public schools these days. It was bad enough when I was in school.
Altogether apart from bogus content (and there’s tons of that) you will see images/pictures on EVERY page.
Maybe that is good for young children, but NOT for older students.
As a young student, I knew the books with all the cutesy pictures were for ‘kids’. I still remember going into the library as a gradeschool student and asking for the books that ‘don't have pictures’.
The librarian called my mother to tell her what I asked for. (it was a small town)
My mother told her to give me whatever I wanted in that library.
