If you haven't read Susan Cain's book Quiet: The Power of Introverts in a World That Can't Stop Talking, I highly recommend it. As an introvert myself, the book left me feeling empowered and clearer and more confident about my strengths. As someone who thinks about education all day, it also had me thinking about what it's like to be an introverted student or an introverted teacher.
Cain has thought a lot about this herself, and includes a lot of advice in the book and on her website.
This interview with NEA Today provides some great advice and insight for educators as well.
The article cites this powerful quotation from the book:
"If you're a teacher, enjoy your gregarious and participatory students. But don't forget to cultivate the shy, the gentle, the autonomous -- the ones with single-minded enthusiasm for chemistry sets or parrot taxonomy or nineteenth-century art. They are the artists, engineers, and thinkers of tomorrow."
