AI image generation is well suited to classroom decoration and slide backgrounds but not to any teaching material a student will learn facts from, because the model cannot verify a single thing it draws.
Teachers are the largest genuinely useful audience for this. The distinction that matters is between material that carries information and material that carries atmosphere. A border, a background, a character, a cover — all fine. A labelled diagram a child will revise from — not fine, at all.
Anything a student might memorise must not be generated. Models invent plausible-looking labels, and a child cannot tell a wrong diagram from a right one — that is the whole reason they are looking at it. Generate the decoration and source the content from a textbook or a proper diagram tool.
