My research focuses on children's learning – especially of mathematics in elementary schools – and the ways in which this can be supported. I attempt to explain how students take up new concepts and contribute to the collective understanding of mathematics in the classroom.

My colleagues and I are completing a National Science Foundation grant to investigate how to support teachers in learning from videos of elementary mathematics classrooms and have recently received a grant from the James S. McDonnell Foundation to pursue similar research questions.

Also, as part of the iLEARN (https://publish.illinois.edu/ilearngroup/) team, I am interested in how the online space provides supports and affordances for students who are traditionally underrepresented in STEM fields. We have funding from the Institute of Education Sciences to investigate this issue.

My research focuses on (1) children's acquisition of knowledge, especially of the sort taught in schools (e.g., children's acquisition of mathematical concepts), (2) the ways in which teachers understand and improve their teaching of mathematics, and (3) the ways in which the online space may provide supports and affordances for students underrepresented in STEM.
