It’s hard to remember a string of facts and figures if you don’t push further. Ask why things are a certain way. How did they come about? Why do they matter? Psychologists call this elaboration. It’s taking class material and “asking a lot of how and why questions about it". In other words, don’t just accept facts at face value. The elaboration helps you combine new information with other things you know. It creates a bigger network in your brain of things that relate to one another. That larger network makes it easier to learn and remember things. You’ll remember facts if you ask questions about why they’re so and how they fit with other things. “Good understanding produces really good memory,” say the experts. If information just seems sort of random, ask more questions. Make sure you can explain the material. Better yet, see if you can explain it to someone else.
