Most brain scientists have not taught 4th grade, and don't know very much about the classroom, even though they might study learning in some detail. Most education professionals, who often know a tremendous amount about the classroom, don't know much about the brain. That is one of the reasons why I am so skeptical about applying brain findings to the classroom.
John MedinaBrain scientists and education scientists don't get together very often, and we end up living in our own little silos.
John MedinaThe brain cannot multitask. Multitasking, when it comes to paying attention, is a myth. The brain naturally focuses on concepts sequentially, one at a timeโฆTo put it bluntly, research shows that we canโt multitask. We are biologically incapable of processing information-rich inputs simultaneouslyโฆStudies show that a person who is interrupted takes 50 percent longer to accomplish a task. Not only that, he or she makes up to 50 percent more errors.

John MedinaThere are estimates that we daily walked for 10 - 20 kilometers for hundreds of thousands of years. The world's best problem solving machinery grew up under conditions of consistent, strenuous physical activity. It makes sense that when we don't recreate the environments in which the organ was forged, we get a loss of function. And that when we do restore those environments, we get that function back. The effects of aerobic exercise on executive function skills is a powerful empirical example of this idea.
