Dr. Leslie Dietiker is an Associate Professor of Mathematics Education at Boston University Wheelock College of Education & Human Development. She currently teaches mathematics and pedagogy courses to future high school mathematics teachers. She is an elected board member of the International Society of the Design and Development of Education (ISDDE) and 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 for 17 years at a public high school in San Francisco, California. She received National Board Certification and was a co-author and managing director of seven CPM textbooks, 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. One study, entitled Mathematically Captivating Learning Experiences (MCLE Project, funded by the National Science 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. Recently, she led a research project entitled Enhancing the Potential of Intended Curriculum (funded by the CPM Educational Program) that studied the variations in how written curriculum is implemented.
