I don't have much faith in it myself, though I don't doubt it's possible to learn some things in that way, and I'm sure I have done. But a lot of the time, being around people who know more than I do about a subject just makes me feel isolated and irritated. For better results they'd need to explain things to me, on my own terms, in a clear way. Anybody wanting me to learn stuff quickly wouldn't make much headway just by exposing me to folks who understand it.
My father taught me my letters and numbers when I was 4 years old, before I started school, and he did a good job. He treated it as a game, and I enjoyed it. Central to his success was his patience, flexibility and tolerance. I was way ahead of the rest of the class from the start.
I sometimes think that
student-centred learning might work quite well on me. Roughly, the student chooses what they want to know about, and the teachers' only role is to be there to answer the student's questions and provide them with whatever materials they ask for. The beauty of it is, I wouldn't have to force myself to take an interest in what they decided I should learn......that's one part of conventional education I didn't fare well with, it kind of worked but the older I got, the more tedious and uncomfortable it became.
