Back when I was an undergrad calculus TA, I participated in a general TA training class. We were taught to be mindful of different "learning types," such as visual learners, audio learners, and kinesthetic learners.

It wasn't until recently that I learned [there is no evidence that these learning styles exist](http://www.changemag.org/Archives/Back%20Issues/September-October%202010/the-myth-of-learning-full.html), (a link to an [actual study](https://www.psychologicalscience.org/index.php/news/releases/learning-styles-debunked-there-is-no-evidence-supporting-auditory-and-visual-learning-psychologists-say.html) for completeness). 

But I began to think about the different ways my calculus students now approach and accept learning. Some people listen to lectures, go to recitations, and are fine. Others read the book and could manage just fine without any listening to me at all. Still others prefer Khan Academy or this style of presentation.

So I wonder:
