ideally you look and fail and exhaust your own efforts, then get unblocked with a tool or assistant or expert. With LLMs at your finger tips who has both the grit to struggle and the self discipline not to quit early? at the age of the typical student - very few.
That actually is an approach. Some teachers make you read the lesson before class, others give you homework on the lesson before lecturing it, and some even quiz you on it on top of that before allowing you to ask questions. I personal feel that trying to learn the material before class helped me learn the material better than coming into class blind.
one could argue aswell that having at least generally satisfying, but at the same time omnipresent "expert assistance" might rather end up empowering you.
Feeling confident to be able to shrug off blockers, that might otherwise turn exploration into a painful egg hunt for trivial unknowns, can easily mean the difference between learning and abandoning.
