"In fact, they found, learning becomes better if conditions are arranged so that students make errors." Well, then, there's no better learning environment than computer programming! "People remember things better, longer, if they are given ... tests at which they are bound to fail." No pain, no gain. I used to wonder why a damaged body part is painful for so long after it has 'made it's point'. After I'd lived long enough to forget several painful lessons, I understood: the longer the pain lasts, the longer the memory lasts. Makes me think scars are evolution's way of helping us to remember.
