In our previous post, we talked about the power of spaced repetition.  But sometimes, a picture is work a thousand words.  Here’s a YouTube simulation comparing spaced repetition with studying topics at random.  The animation shows a steady stream of new material being learned (like what you’re learning in class) and contrasts studying randomly (like when you review from a note sheet) with spaced repetition.  Fresh memories show up as brightly colored circles, as you forget a fact, it fades into black.  At the end, compare how much you’re losing with random study, and how much better spaced repetition fares.
