I've had very good luck using LLMs to do this. I paste the part of the book that I don't understand and ask questions about it.
Asking the right kind of questions is a genuine skill.
It applies to every domain of life where you are at the mercy of a "professional" or at the mercy of some knowledge differential. So you need to be a good judge of whether the answers you're getting are good answers or bad answers.
A skill we cannot rely kids to have, and which i think takes years of training and learning for even adults to really acquire. (to be clear, i'm not thinking about AI prompting. I 'm thinking about assumption breaking and understanding prodding questions the learner asks themselves and seeks answers for, to build and refine their mental models of something they learn)
Because questions are fundamentally about knowledge differentials, which will always exist for individual human beings. We can't at any point know everything.
Know how to know what you don't know and get a good grasp of what it means to know in the first place.
Knowledge isn't absolute.
A great question can compensate for a simple answer.
Kids can ask questions, but they rely on an experienced teacher to effectively answer.
Teaching someone effectively through answering questions, require the teacher through the students questions to build a model of the students model. To answer not only the question directly, but also the question that should have been asked instead.
A good end-of-chapter quiz doesn't check that a reader read the next. It asks questions whos answer rule out possible (or common) incorrect mental models the reader may have built.
A learner skilled in asking truly excellent questions, makes questions for which even a bad or simple answer rule out and refine their assumptions.
And that is a skill i doubt is ever truly mastered.
Its like the X Y. A great teacher answers X instead of Y. A great learner asks about X in the firstplace.
