The need to recruit and prepare more physics teachers could not be clearer. The National Academies' report Rising Above the Gathering Storm states that the most consistent and powerful predictor of student achievement in science and mathematics is a teacher who is fully certified and has at least a bachelor's degree in the content area; however, two thirds of today's high school physics teachers did not major in physics, and over 90% of middle school physical science students are taught by teachers without a physical science major or certification. The American Association for Employment in Education consistently lists high school physics as one of the fields with the most severe teacher shortages. We will continue to see these kinds of statistics until physics departments around the country become deeply involved in teacher preparation.
