>I've been working with educators for a while, and they've said that "learning styles" are just a myth with no solid evidence

I've worked with educators too. They are and they aren't it depends on the level and time period you're taking. At the individual level how a math problem (for example) is presented can affect how quickly a student grasps the concept. When you're taking an entire school and more than a decade of schooling the effects of presentation aren't all that meaningful because people do the best job retaining the knowledge they use frequently.
