Traci Higgins, Ph.D. is a Senior Research Associate on the Evaluating DMI project. Her work focuses on the development of measures of teaching and learning that can get beyond the surface level features of both. She has studied the impact of DMI on pedagogical content knowledge and mathematical knowledge for teaching in previous research and seeks to better understand how that knowledge translates into teaching practices that support learning for understanding. She was a member of the working group that produced “Using Statistics Effectively in Mathematics Education Research” and has co-authored book chapters, articles, and reports including a recent article in the Journal for Research in Mathematics Education describing research on the impact of DMI. Outside of work she can be found coaching youth sports, cooking, playing with her kids, and running her border collie-greyhound mix.
