Dr. Leslie Dietiker is an assistant professor of Mathematics Education and teaches courses in mathematics and pedagogy to future high school mathematics teachers as well as research and theories in mathematics curriculum to masters and doctoral students. She is an elected board member of the International Society of the Design and Development of Education (ISDDE) and is on the Editorial Board of the American Educational Research Journal (AERJ), a leading publication of the American Educational Research Association (AERA). Dr. Dietiker also designs and leads professional development for schools and districts in the Boston region.
Prior to coming to BU, Dr. Dietiker taught high school mathematics and computer science at a public high school in San Francisco, California, for 17 years. She also has received National Board Certification. She also is a lead author of seven mathematics textbooks for grades 6–12 with the nonprofit CPM Educational Program. These include Core Connections Algebra and Calculus.
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 understanding how teachers use textual materials and plan lessons. One study, entitled Characteristics of Interesting Mathematics Lessons (funded by the William T. Grant Foundation), 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. She also recently completed the EPIC research project, which studied the variations in how written curriculum is implemented. Currently, she is leading the MCLE Project (Mathematically Captivating Lesson Experiences), funded by the National Science Foundation, to learn how the design of mathematics lessons can attract or repel students.

Dr. Dietiker's research focus in on the quality and structure of mathematics curriculum as found in textbooks, lesson plans, and enacted in classrooms. It builds on existing theory (e.g., Dewey) on the meaning and purpose of curriculum in general, and mathematics curriculum in particular.Read more about Dr. Dietiker's research.
