Here's a wonderful short video that the BBC just put out explaining introversion. The fact is that our current American society is unknowingly hostile toward introverts quite often. This is also the case in our schools where somehow we've gotten it into our collective heads that we should be forcing students to constantly talk to each other. To be sure the extroverted students in school love this. And since they make up the majority of the general population (and are by their very nature the most outspoken when compared to introverts) it's easy to see why the situation has devolved into its current state. Constantly being forced to talk is a huge stressor to introverts, however. My own children tell me they can't stand the "Turn and talk to your shoulder partner" activity constantly being done in classrooms now. I hate it when it's done to me in staff development trainings as well. And as usual in education, there is absolutely no actual research backing this latest fad up. This wonderful little video lets introverts know that not only is there absolutely nothing wrong with them, but that introversion is a needed trait within society.
And then to follow it up, here is a TED talk by Susan Cain, the author of the phenomenal book Quiet: The Power of Introverts in a World That Can't Stop Talking. Her book should be required reading for all educators. We must respect all sides of the spectrum of interpersonal communication in education if we are going to meet the needs of all students.
