Assistant Professor, Department of Curriculum and Instruction, College of Education
Expertise: My research focuses primarily on theorizing the nature of short- and long-term interests in STEM disciplines, and designing learning environments that are truly engaging to students. This has led me to investigate learning and interest-based participation in settings as diverse as classrooms, after-school programs, and hobby practices (model rocketry and amateurs astronomy). Intersecting with this central research focus, my other research interests include the use and creation of technical representations and the way these mediate knowing and learning; the discourse and practices of engaged participation in STEM classrooms; and social justice issues in STEM education. This work has appeared in publications such as the Journal of the Learning Sciences, Cognition and Instruction, and the Journal of Mathematical Behavior.
