The summary message is there is no evidence to suggest that people have individual learning styles (in any of the various forms in which they are peddled) and so benefit from having material presented to them in some specific way.

However, there is evidence that children benefit from being presented information in a variety of different formats, so teachers should seek to use different styles of delivery - its just they should avoid notions that child X should have stuff presented like this and child Y should have stuff presented like that.
