Sybilla Beckmann is Josiah Meigs Distinguished Teaching Professor of Mathematics at the University of Georgia. She has a PhD in mathematics from the University of Pennsylvania and taught at Yale University as a J. W. Gibbs Instructor of Mathematics. Beckmann has done research in Arithmetic Geometry, but her current main interests are the mathematical education of teachers and mathematics content for students at all levels, but especially for PreK through the middle grades. Beckmann developed mathematics content courses for prospective elementary school teachers at the University of Georgia and wrote a book for such courses, Mathematics for Elementary Teachers, now in a third edition. She is interested in helping college faculty learn to teach mathematics content courses for elementary and middle grades teachers and she works with graduate students and postdoctoral fellows toward that end. As part of this effort, Beckmann directs the Mathematicians Educating Future Teachers (MEFT) component of the University of Georgia Mathematics Department's VIGRE II grant. Beckmann was a member of the writing team of NCTM's Curriculum Focal Points for Prekindergarten through Grade 8 Mathematics, was a member of Committee on Early Childhood Mathematics of the National Research Council and co-author of its report, Mathematics Learning in Early Childhood: Paths Toward Excellence and Equity, has worked on the development of several state mathematics standards, and was a member of the mathematics writing team for the Common Core State Standards Initiative. Several years ago Beckmann taught an average 6th grade mathematics class every day at a local public school in order to better understand school mathematics teaching.
