Here's a quick response as I have to get to a sailboat race.
* Most research is limited; most test memory of pictures vs words (pictures win for most). Most educators of higher levels believe that there is more to learning than memory, but this is largely not addressed by the researchers.
* Most "learning styles" are established via questionnaire, not actually testing how people learn best
* Even the "Learning Styles is BS" crowd is starting to weasel out of the implication of their conclusion that everybody learns the same. They are saying things like "talent" and "context" etc. give differences in how people learn, not learning styles. A distinction without a difference IMHO- with the possible exception that you could argue that you are, for example, verbal for math and visual for history or something (because of context or whatever).
* I don't have a dog in the fight. I only want what's best for students, which means to learn how they learn. If they are all the same, so be it (but I would be surprised).
* More of my thoughts here: https://studyswami.com/are-learning-styles-bs/ and my conceptual take on how we should measure learning styles if we really want to research them (don't take the actual results too seriously).
Even if it's a thing, the idea that a teacher should take on the role of psychologists and figure out a child's optimal learning style should be preposterous to anyone with common sense.
It might work in combination with a software suite, with e-readers getting cheaper and more capable, and easily lasting through a school day, it's an option.
Ah yes, we can sort kids into humanities and sciences, by age, by ability, into gymnasiums and normal schools, but sorting visual learners from other ones is too hard.
We can only seperate kids into groups when it serves adninistrative or industrial beenfits, when its for the benefit of the child, forget it.
I mean how can you expect a ridiculously expensive system where children spend the majority of their waking hours to actually ask a child if it suits them?
