Educational mathematics

I am currently involved in extensive mathematics curriculum innovation projects. My first book, Experiencing Geometry on Plane and Sphere (1996), has appeared in an expanded and revised third edition: Experiencing Geometry: Euclidean and Non-Euclidean With History (with Daina Taimina; Pearson Prentice-Hall, 2005). My second book, Differential Geometry: A Geometric Introduction (1998) has appeared in a Revised Second Edition (2005), and a new e-book Self Study Edition is due in 2012. In 2005, I accepted an invitation to join the high school curriculum development team for Robert Moses’ Algebra Project and am the lead writer for the geometry portions of the Algebra Project high school curriculum. In 2011, I accepted an invitation to join Richard Lehrer (Developmental Psychology, Vanderbilt University) in an NSF-supported project to develop and test the potential of experiencing, describing, and visualizing space as the core of an integrated STEM education that spans the K–5 grades. I am providing overall mathematical guidance to the project and designing instructional materials to support student investigations.
