When my son was in elementary school I knew that he had some learning differences, so I studied how people learn to better understand how to optimize his own learning process.  What is interesting is that I learned so much that applies to all of us!  For example, take a look at these statistics.  Students retain:

-10% of what they read -26% of what they hear -30% of what they see -50% of what they see and hear -70% of what they say and -90% of what they say and do.

So if we want to optimize our own learning, it helps to learn in a multi-sensory environment.  Read it, listen to it, say it out loud, experience it by doing it yourself.
