- B.S. in Mathematics, California State University, San Luis Obispo

## Profile

Dr. Leslie Dietiker is an assistant professor of Mathematics Education at Boston University where she is part of the Arts and Science Education cluster. She currently teaches mathematics and pedagogy to future high school mathematics teachers. Prior to coming to BU, Dr. Dietiker taught high school mathematics and computer science at a public high school in San Francisco, CA for 17 years and received National Board Certification. While teaching she co-authored seven textbooks for grades 6-12 with the non-profit CPM Educational Program and served as Director of Curriculum, including Algebra Connections and Geometry Connections. Dr. Dietiker’s research focuses on the theory of curriculum, particularly with regards to its aesthetics and structural dimensions. Other areas of professional interest include supporting teacher curricular work, such as ways to use textual materials and plan lessons. Her current grant, entitled Characteristics of Interesting Mathematics Lessons (funded by the William T. Grant Foundation), is focused on learning how the mathematical plots of algebra lessons that students indicate are interesting differ from those that are not characterized as interesting by students.
