When praise becomes the reward, the strategy is to do whatever it takes to get praise. When success is the reward, the strategy becomes learning how to succeed, which often means passing through failure. We all have an innate ability to find the success strategy. For example, video games have no mercy--the only way to succeed is to keep trying until you get better. And yet most kids will continue to play a new game until they improve because, in this case, learning is an adventure, its own reward. The best teachers seem to apply this to the classroom.
