Many people (including me) learn much better from listening to a person talk than from reading textbooks, even with no avenue to communicate back to that person.
You likely don't know how to read textbooks correctly. It's a legitimate problem in school systems around the world - most kids are taught from an early age to do exactly what the teacher says and that's how you learn. Thus, they never learn anything on their own.
I doubt you could come up with anything since you can only learn from other people, apparently. "Learning styles" is just another way of pronouncing "lazy".
