One path to knowledge is to answer questions on stackoverflow about them - i.e. google, look at docs, try things, think, etc. This works when askers don't know how to work things out for themselves.

Maybe that's what they need to learn; though maybe they aren't interested in learning it...

OTOH I find many maths explanations wouldn't make sense if I wasn't able to already "imagine it inside my mind by myself" i.e if I didn't already understand it. IMHO this is the fundamental problem of education...
