Slate featured this excerpt from Learn Better about how, in order to get better at something, you need to know what you’re doing wrong.
Smart, focused criticism helps us figure out how to improve. Feedback makes us realize what we’re doing wrong and how we can do it right. As researcher John Hattie writes in his book Visible Learning, “the most powerful single influence enhancing achievement is feedback.
”I’ll admit that I had long ignored this fact in my basketball life. Before pick-up games, I’d often go to the local gym to try and improve but I wouldn’t really monitor my outcomes. I didn’t get any feedback on my footwork or track the number of shots that fell in. Practice expert Anders Ericsson sees this all the time, and he told me that when most people practice, “they don’t have a clear idea of what they should improve, and so they’re just wasting their time.
When it came to hoops, better forms of practice¾and targeted feedback¾eventually came in the form of Dwane Samuels. During his 20s, Samuels had played basketball at some big-name colleges, notching up minutes in summer leagues against NBA All-Stars like Ben Wallace. Later, Samuels found a spot playing for the Washington Generals, the Harlem Globetrotters’ perennial opponents.
