Sometime in the not so distant past, one of your kids, or a kid you know, has probably been told that she has a particular learning style. Perhaps she is a visual learner, who absorbs information best through images. Or maybe an auditory one, who needs to hear things to really grasp them. Boys are often told they are kinesthetic learners, deriving the most from a lesson through movement. It’s all bunk. “There is no credible evidence that learning styles exist,” says Daniel Willingham, a professor of psychology at the University of Virginia.
