I am looking for the expert who has made this theory: three levels of reading comprehension. Literal, inferential, and evaluative comp?

I can't find an exact reference for this but a library might be able to help. You'll need one that has an education department.

Your next step is to know what you are looking for and how to find it. Here is one reference that when you put it into amazon, will lead you to others. All look like they are common and should have an answer that you seek.

If that does not work, the library at a university (where you will be most welcome) and the librarian should be able to get you what you seek. Those ladies are real magicians with there magic references.

Do not be ashamed or shy about asking for help.

However, I don't have enough money to buy that ebook :(
