Doing. - Tutorials and step by steps via video or reading sometimes assist in this, but often they are to slow. This assumes we are talking about "learning" how to do something-- not for instance "learning" who the first 5 presidents of the US had been. In this case though "research" -- using multiple sources and short bursts of reading from those sources relative to the topic provide the longest lasting knowledge for me. Then toss something in like a long form biography or history book after the research has established interest, or even doing more research after the book has established more interest.
