Nothing has been more rewarding than working as a Calculus lab instructor. In the lab, because of its small size and informal nature, students can discuss, freely, their particular difficulties. As the group leader, I turn these individual questions into general discussion topics. And by repeating this process in many different forms, I eventually begin to see my objective achieved: frustration and confusion transformed into enthusiasm and understanding. It is this transformation from confusion to the understanding capable of most Calculus students that makes my job worthwhile.
