## Research Statement

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<i> the collective memory of the class</i> 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. In the future, I expect to have a detailed description of teaching moves to manage students’ prior knowledge in problem-based instruction. I am also interested in developing applications of my findings for the purpose of teacher education through the design of innovative rich-media environments that would 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.
