My entire life, listening to classroom lecture has been an absolute struggle for me. It requires a monumental amount of effort and willpower to pay attention, process and retain all that info at the same time. On the other hand, I can read something once and If I can handle the material, I typically retain it effortlessly. I know a lot of other people that cannot self-educate via reading. This study seems to be suggesting something similar to a denial that introverted and extroverted types exist. How can they not? Im a little suspicious of the proposition: poor results when current matching styles to lessons = learning styles do not exist.
