CEDAR FALLS, Iowa -- Paul Trafton, professor of mathematics at the University of Northern Iowa, will present the annual Sahai Lecture at 4 p.m. Monday, Nov. 25, in the Great Reading Room of Seerley Hall on the UNI campus.

The title of Trafton's talk is 'Young Children Do Powerful Mathematics: A Decade of Research and Development on Student Learning and Teacher Change.' He will focus on highlights of research in primary grade classrooms on the effects of a problem-centered instructional model and a constructivist approach to teacher development.

A member of the UNI faculty since 1991, Trafton is the co-author, with UNI professor of mathematics Diane Thiessen, of 'Learning Through Problems: Number Sense and Computational Strategies,' a practical resource book for primary teachers that summarizes Trafton and Thiessen's research on the problem-centered instructional model. Trafton holds a Ph.D. from the University of Michigan and is the author of numerous articles published in professional journals.

The Prem Sahai Distinguished Professorship in the UNI College of Natural Sciences, established in honor of the late Dr. Prem Sahai, is awarded annually, on a rotating basis, to a faculty member from the department of biology, chemistry or mathematics who exemplifies excellence in his or her discipline. Each Sahai Distinguished Professor delivers a lecture as part of the award.

Sahai, who came to Iowa from New Delhi, India, earned three degrees from UNI: a master's degree in education with a major in mathematics in 1958, a specialist's degree in communication media in 1967, and a master's degree in education with a major in biology in 1970. His oldest son, Subhash, also a UNI alumnus, practices in the family-owned medical clinic in Webster City, along with his wife and brother.

The lecture, which is open to the public and free of charge, will be preceded by an informal reception outside of the Great Reading Room.
