Whenever I think about personalized learning, I drift toward the ways adults learn. We know what we like, how we remember things, the topics that interest us, and the best ways to absorb new information. It's easy for us. I know I'm a kinesthetic learner so I recall things much better if I'm active. For example, I like to listen to audiobooks and podcasts while I'm running, doing yard work, or driving because I remember a lot more when I associate a passage or new bit of information with what I was doing at the time. But students don't have the years (decades) or experience to know what works for them—they're still going through trial and error and as adults, we need to give them every chance they can get to play around with their own learning.
