A survey of 722 physics faculty conducted in 2008 found that many physics instructors had knowledge of research-based instructional strategies (RBISs), were interested in using more, but often discontinued use after trying. Considerable effort has been made during the decade following 2008 to develop and disseminate RBISs in physics as well as change the culture within the physics community to value RBIS use and other forms of student-centered instruction. This paper uses data from a 2019 survey of 1176 physics instructors to understand the current state of RBIS use in college-level introductory physics, thus allowing us to better understand some of the impacts of these efforts on physics instruction. Results show that self-reported knowledge and use of RBISs has increased considerably and discontinuation is now relatively low. However, although the percentage of time lecturing is less than 10 years ago, many instructors still engage in substantial lecturing (i.e., more than one-third of class time). Relatedly, we find that the majority of RBIS use centers on pedagogies designed to supplement a primarily lecture-based classroom rather than pedagogies designed to support a primarily active learning classroom. This suggests that the physics education research community and beyond has done well promoting knowledge about RBISs and inspiring instructors to try RBISs in their courses. But, there is still room to improve. Based on available evidence about effective instructional practices, we recommend that change agents focus on supporting instructors to increase the percent of class time in active learning and to implement higher impact strategies.
