Neither. I prefer to learn by doing.

It's not even close and it's always been this way.

In school, I really had trouble following lectures. Taking notes helped. It was hard to focus reading at night. Writing in the book helped. For homework, whenever I wrote or solved problems, I retained it forever (it seems).

At work, I rarely understand what someone's talking about when explaining or demonstrating something new to me. So I invariably say, "Stop! Tell me what to do and I'll do it." If they go too fast, I tell them to slow down. This has been the single most important thing I've done with learning in business, for myself and with others. I never teach by lecturing or writing (except here one the internet, of course); I always make the student do it while I tell them what to do. This is the only real way I've ever been able to assure myself that they'll remember.

Just this morning, I had trouble with the credit card swiper at the store register and asked for help. The attendant jumped in and starting hitting buttons. As usual, I yelled, "Stop! Tell me what to do and I'll do it. How else will I learn?"

As the old Chinese proverb said:

  Tell me, I’ll forget
  Show me, I’ll remember 
  Involve me, I’ll understand
