Every four years we survey a nationally representative sample of high school physics teachers. We define anyone who teaches at least one physics class to be a "physics teacher." About 40% of these teachers teach a majority of their classes in subjects other than physics. We also ask teachers to rate how well prepared they felt in various aspects of teaching. The response choices are "not adequately prepared," "adequately prepared," and "very well prepared." The accompanying figure shows the proportion of teachers who reported feeling adequately or very well prepared in the following aspects of teaching: •Basic physics knowledge, •Other science knowledge, • Application of physics to everyday experience, •Use of demonstrations,•Instructional laboratory design, •Use of computers in physics instruction and labs, and •Recent developments in physics. © 2016 American Association of Physics Teachers.
