About the Authors
is a University Distinguished Professor of Mathematics and Director of the Institute for Mathematics and Education at the University of Arizona. Born in Sydney, Australia in 1956, he received his Ph.D. in Mathematics from Harvard University in 1984, under the supervision of Barry Mazur. After spending two years at the University of California, Berkeley, and one at the Mathematical Sciences Research Institute in Berkeley, he joined the faculty at the University of Arizona in 1987. In 1989 he joined the Harvard calculus consortium, and is the lead author of the consortium's multivariable calculus and college algebra texts. In 1993-94 he spent a year at the Institut des Hautes Etudes Scientifiques, and in 1995-96 he spent a year at the Institute for Advanced Study on a Centennial Fellowship from the American Mathematical Society. In 2005 he received the Director's Award for Distinguished Teaching Scholars from the National Science Foundation. His professional interests include arithmetical algebraic geometry and mathematics education. He has received grants and written articles, essays, and books in both areas.
is the lead author of Functions Modeling Change: A Preparation for Calculus, a precalculus book, published by John Wiley & Sons, Inc. Eric has taught at Harvard College, the Harvard Kennedy School of Government, the Harvard Extension School, and Wellesley College. He was awarded the 1999 International Conference on Technology in Collegiate Mathematics (ICTCM) Award for Excellence and Innovation with the Use of Technology in Collegiate Mathematics and the Petra T. Shattuck Excellence in Teaching Award in 2005. Eric began his teaching career at Harvard University in 1989, shortly after graduating from Cornell University with a B.A. in Physics in 1988. He joined Wellesley College as coordinator of its Quantitative Reasoning (QR) Program in 1995. At the time, this innovative program encompassed several new undergraduate degree requirements as well as a course in basic math and data analysis. Together with a colleague, who joined the program in 1998, he administered all aspects of the QR program and the associated degree requirements. Eric joined a software startup company, Elytics, Inc., in 2000, as a software engineer. He is now working as Director of Engineering on a new online math pro ject under development by several members of the Mathematics Consortium Working Group. He continues to teach math at the Extension School and occasionally at the Harvard Kennedy School.
is a professor of mathematics at the University of Arizona; from 1991 to 1998 she was a professor of Practice in the Teaching of Mathematics at Harvard University. She was a principal investigator for the National Science Foundation (NSF)-funded Bridge Calculus Consortium. She has served on committees for the Graduate Record Examination and the Massachusetts state mathematics framework review process, and on the Mathematics and Science Teacher Education Program (MASTEP) Advisory Board, an NSF-funded program to improve teacher training in California. Dr. Hughes Hallett served on the NRC's Committee on Information Technology in Undergraduate Education. A Fulbright Scholar, she received M.A. degrees from both Harvard University and the University of Cambridge, England.
