Expertise

My research interests include K-12 students’ construction of quantitative and algebraic reasoning, with a particular focus on how middle school students construct rational number knowledge and algebraic reasoning. I also currently study how to differentiate mathematics instruction for middle school students in a large project (see below). Finally, I have significant interests in how student-teacher relationships influence mathematical teaching and learning and in issues of equity.
