Christian Jarrett:

The idea that we learn better when taught via our preferred modality or “learning style” – such as visually, orally, or by doing – is not supported by evidence. Nonetheless the concept remains hugely popular, no doubt in part because learning via our preferred style can lead us to feel like we’ve learned more, even though we haven’t.

Some advocates of the learning styles approach argue that the reason for the lack of evidence to date is that students do so much of their learning outside of class. According to this view, psychologists have failed to find evidence for learning styles because they’ve focused too narrowly on whether it is beneficial to have congruence between teaching style and preferred learning style. Instead, they say psychologists should look for the beneficial effects of students studying outside of class in a manner that is consistent with their learning style.
