The quote above is from the article but it really comes from a wonderful woman who taught my methods class back when I was learning to be a teacher. While I have long since lost forgotten her name, the charge she gave us to keep up with student learning as it has evolved as not been forgotten by me in the twenty-five years since she said it to me.
