People learn different ways, but it's rare (and unnatural) for a person to only learn one way. So the thing to do is to present material and experiences that cover all the ways to learn. Some will do a child more good than others. One child might learn one thing very visually, and another thing tactilely. So instead of wasting ANY time trying to find out how they learn, spend good time learning (yourself) how children learn naturally with all their senses, with all their ways of thinking, or with their own best favorites from moment to moment.
