How Interleaving seems harder, but works better.
By: Brailyn Zimmerman
Let me guess… you go to study for a test by rereading the same material, focusing on one subject for hours until it “feels” mastered, or doing the same problems over until you physically can’t, just to get to the exam and realize that all the cramming didn’t work as well as you thought.
It’s okay, you aren’t alone! Most of us study this way because it’s organized and productive, right? Cognitive psychology research suggests this may be one of the least effective ways to learn.
That disconnect is exactly why interleaving is such a game-changer. Mixing up different types of problems or topics during the study session instead of focusing on one at a time may feel harder in the moment, but research in cognitive psychology shows it actually leads to better learning and retention in the long run.1
