Heterodoxy

TheHeterodoxy section of teacher-trainer James Atherton's website has a wonderfully tongue-in-cheek piece on learning styles:
Learning styles don't matter

There's 'orthodox' coverage of learning theories, too:
Angles on Learning: An introduction to theories of learning for college, adult and professional education

Atherton describes himself as "a pragmatic practitioner, sceptical about any panaceas, who nevertheless believes that every practical choice embodies a value-position which is worthy of discussion."

It's a lovely site to visit, with some great design touches.
