The research (UK study, Hal Pashler's recent US study) says learning style instruments are garbage, and there's no evidence that teaching to 'styles' is of any use. While there are reasons to recognize learners are different, the current take-home is still to use the right medium for the message.

So I lump most learning styles with other snake-oil like multi-generational differences, digital natives, multi-tasking, brain science, etc.

There are roles for talking about each of them, but they're so grossly misused that perhaps it's better to dissuade people until the bad noise has gone away! I laud your efforts to straighten out the concepts, but I worry that the light won't make it through the noise and smoke. Not quite sure how to hold such a deep conversation in a public forum, but welcome the effort.
