Bob Horton joined the Clemson faculty in 1998, appointed as Assistant Professor of Secondary Math Education. Prior to this, he taught both high school and junior high school mathematics, including a four-year stint as math department head. He also taught college math and statistics for several years as an adjunct. During the 1980’s he took a six-year hiatus from teaching to work in the Network Training Center for AT&T, where he developed and taught courses and also worked as a technical writer. He has a B.S. from the University of Wisconsin Madison, an M.Ed. from Miami University (Ohio), and an Ed.D. from the University of Cincinnati. For the G K-12 project, he serves, along with Bill Leonard, as co-instructor for the summer course and joins the other PI’s in participating in our fall meetings. His interests focus around the use of technology in promoting mathematical understanding and in using mathematics to create models of real world phenomena.
