Norma Presmeg

Norma Christine Presmeg is a retired mathematics education researcher whose work has concerned mathematical visualization, semiotics, and ethnomathematics, and their role in secondary-school mathematics teaching and learning. Presmeg is originally from South Africa, was educated in South Africa and England, and worked in the US, where she is professor emeritus of mathematics at Illinois State University.

Education and career
Presmeg has a bachelor's degree in mathematics and physics from Rhodes University in South Africa, with bachelor's honours in mathematics and a bachelor's degree in education from the University of Natal. She taught high school mathematics in South Africa from the mid-1960s to the late 1970s, and earned a master's degree in education in 1980 at the University of Natal. She completed a Ph.D. at the University of Cambridge in England, in 1985. Her dissertation,  The Role of Visually Mediated Processes in High School Mathematics: A Classroom Investigation, was supervised by Alan J. Bishop.

After returning to South Africa for a five-year stint at the University of Durban-Westville, she moved to the US in 1990, as a faculty member in Curriculum and Instruction at Florida State University. Ten years later, she moved to Illinois State University, where she is retired as a professor emeritus.
