“Good luck on your first day as an assistant professor, Dr. Tanner! Have a great class!” On the wall above my desk, these words scream out from an otherwise encouraging note that is adorned with many exclamation points. This note has hung on my wall since my very first day as an Assistant Professor of Biology. As I was charging off to teach my first class, a senior faculty member who had been on my hiring committee slipped this note under my office door. In moments of pause years later, I still stare up at that note and breathe a sigh of relief that I had much more than luck to guide me on my first day as a college-level teacher. Although I continue to have much to learn—as all of us do no matter the number of years of teaching experience—I did arrive at the university with both formal and informal training in science education. I had had plenty of exposure to innovative pedagogical approaches, questioning strategies, and techniques for engaging diverse audiences in learning science. As a scientist educator, I had had the privilege of many years of collaboration with outstanding K–12 educators as well as a postdoctoral fellowship in science education. However, my training has been, to say the least, unconventional compared with that of my fellow junior faculty and unique in its preparation in regard to the teaching and learning of my discipline. It will not be news to anyone reading this article that university and college teaching is to a large extent a profession with no formal training. It’s startling but true that the majority of faculty members—and lecturers who often teach large numbers of students—have no formal training in the teaching and learning of their discipline. In fact, the hiring process in university science departments is structured primarily to evaluate a faculty candidate’s ability to be a productive researcher, with success measured in number of publications and magnitude of grant funds raised. Depending on the type of institution, for example, research university, state-level university, or liberal arts college, there may be a component of the faculty interview process that probes a candidate’s teaching ability, for example, requesting a statement of teaching philosophy and requiring the candidate to teach a sample lecture class. However, this sample lecture often screens for gross inadequacies, rather than looking for stellar innovations or pedagogical skills. This lack of formal, accredited training for university and college instructors stands in stark contrast to the requirements for a high school teacher who is charged with the education of students only a year junior to college freshmen. High school teachers in the United States must be credentialed as a secondary science teacher, demonstrate subject matter competency in every subject that they will be teaching, and must continually engage in professional development in the teaching and learning of their discipline throughout their career as a science teacher. With the 2002 federal No Child Left Behind legislation, the onus is upon each precollege science teacher to become “highly qualified” in terms of formal university-level training in science education. However, no such required professional training or measurable standards for teaching are required in institutions of higher education. Many policy documents have suggested standards of teaching practice in postsecondary science education (National Research Council, 1996, 1997; Siebert and McIntosh, 2001), but the extent of implementation of these ideals is unclear and has gone relatively unstudied, although national and regional accreditation boards do look at outcomes, asking colleges and universities to assess what their students have gained from four years of study at their institutions. Nonetheless, there is a striking reversal of accountability that happens when one crosses the precollege teaching to college-level teaching boundary (Table 1). During the K–12 school years, society expects K–12 teachers to be responsible for student learning. Salaries of teachers in many states are tied to student test scores, and poor student performance can potentially invoke penalties. At a college or university, several variables in the educational universe shift. Students are the ones responsible for learning.
