I study how young people make sense of complex problems in mathematics and science, and how to support such sensemaking. As part of this work, I design computational toolkits with the goal of empowering young people to share, formalize, and test their own ideas about how the world works. You can find some examples of this at the Expressive Technologies Lab website.
Two projects I’m working on currently are: SiMSAM (Simulation, Measurement, and Stop-Action Moviemaking), to explore how we can support computational modeling in the middle grades, and DataSketch, to investigate and help support the development of young learners’ data visualization competencies. I’ve also got ongoing work that explores how young people make sense of the mathematical patterns generated by complex systems that involve many interacting, at times conflicting elements.
I’m affiliated with the Tufts Center for Engineering Education and Outreach, the Poincare Institute, and Tufts’ Cognitive Science Program. Visit me on github and Google Scholar. I got my PhD in Learning Sciences at Northwestern University, and also hold undergraduate degrees in Elementary Education and Mathematics.
