I created a course called Myths, Legends, and Lies in Education for this very reason – I was tired of the misunderstanding (and excuses) that I heard in a teacher education about learning styles. I agree with your points and, while I am not saying that learning preferences don’t exist, catering to them specifically in an individual basis is not the way to go. In a subsequent issue of the journal that published the Kirschner, Sweller, and Clark article (yes, all cognitivists), several big names in the field refute the claims that KS&C make – primarily that constructivist strategies are not ‘unguided’.

I offer this article that I co-authored as to the contextual effectiveness of PBL.
