James Stuart Tanton (born August 1, 1966) is a mathematician and math educator. He is a winner of the Kidder Faculty Prize for his teaching at The St. Mark’s Math Institute, scholar at the Mathematical Association of America, author of over ten books on mathematics, curriculum, and education, and creator of videos on mathematics on YouTube. As of November 2012 his approximately 170 videos had earned over 270,000 views.
Education and professional work
Tanton received his B.A. in mathematics from the University of Adelaide, and he earned his Ph.D. in mathematics from Princeton University in 1994, with a thesis in algebraic topology titled A Homological Fibration for Gl [infinity]. He taught at the New College, St. Mary's College of Maryland, and Merrimack College before deciding that, to gain credibility with the high school teachers he hoped to work with, he had to teach high school himself. Tanton taught at St. Mark’s School in Southborough, Massachusetts, from 2002 to 2011. He is now a visiting scholar at the Mathematical Association of America in Washington, DC.
Tanton’s professional focus is on reforming the secondary mathematics curriculum to bring a sense of joy and discovery to the topic.
