Research & Service

My research focuses on how teachers manage students’ prior knowledge. I am interested in examining teachers’ decision-making when handling students’ prior knowledge and the rationality underlying those decisions. I have studied this question in the particular case of the high school geometry class, which has special demands for the teaching and learning of mathematics. Methodologically, I apply Systemic Functional Linguistics to the analysis of both classroom talk and discussions among teachers.

I have found that geometry teachers shape the collective memory of the class with timely actions geared towards making students remember something from the past or towards making something memorable in the future. Moreover, geometry teachers not only control what students have to remember, but also what students have to forget as a result of teaching with a problem.

I am currently leading a project funded by the National Science Foundation. The project, CAREER: Noticing and Using Students' Prior Knowledge in Problem-Based Instruction has the goal of promoting teacher attention to student thinking through their involvement in a professional development intervention. The intervention is novel by combining three activities that have been effective for promoting teacher learning in isolation: Lesson Study, animations of classroom instruction, and video clubs. We are developing a framework for combining these activities in professional development. In addition, we are producing resources to scaffold how teachers consider students' prior knowledge as they plan mathematical tasks for their students.

I have a special interest in the teaching and learning of geometry. In the past, I have investigated relationships between justifications for teaching geometry and the historical development of the American high school geometry curriculum. I have also studied how the use of dynamic geometry provokes new challenges and possibilities in geometry classrooms.
