About the Author
Ricardo Fierro received a Bachelor of Science degree in Mathematics from the University of California, Davis, and a Ph.D. in Mathematics from the University of California, San Diego (UCSD). He was awarded the President's Dissertation Year Fellowship while completing his Ph.D. at UCSD, and the President's Postdoctoral Fellowship at University of California, Los Angeles, where he continued his research. He has been a faculty member in the Department of Mathematics at California State University San Marcos (CSUSM) since 1992. In addition to teaching mathematics for prospective elementary school teachers, he has taught such courses as numerical analysis and computing, optimization, modern geometry, probability and statistics, linear algebra, college algebra, modern algebra, discrete mathematics, and business calculus. To enrich his understanding of teaching at the grade school level, he spent a sabbatical leave teaching fourth, fifth, and sixth graders at an elementary school, and regularly volunteers as a mathematics teacher at local elementary schools. Professor Fierro is a member of the American Mathematical Association of Two-Year Colleges and the National Council of Teachers of Mathematics. He is married with two children.
