At my institution, several courses are self-paced and instructors are there to help students who have difficulties with the information, or applying the information. I don't think this type of class lends itself to learning styles, primarily because the help is individual, and based on the progress the student has made. It would be difficult to halt the entire class to discuss a problem because each student is at a different place in the book, and may understand what this student does not. This type of atmosphere makes learning styles a moot point, don't you think?
