Alfred S. Posamentier (born October 18, 1942) is an American educator and a lead commentator on American math and science education, regularly contributing to The New York Times and other news publications. ^[1] He has created original math and science curricula, emphasized the need for increased math and science funding, promulgated criteria by which to select math and science educators, advocated the importance of involving parents in K-12 math and science education, and provided myriad curricular solutions for teaching critical thinking in math.

Dr. Posamentier was a member of the New York State Education Commissioner's Blue Ribbon Panel on the Math-A Regents Exams. He served on the Commissioner's Mathematics Standards Committee, which redefined the Standards for New York State. And he served on the New York City schools’ Chancellor's Math Advisory Panel. ^[2]

Posamentier earned a Ph.D. in mathematics education from Fordham University (1973), a master's degree in mathematics education from the City College of the City University of New York (1966) and an A.B. degree in mathematics from Hunter College of the City University of New York. ^[3]

Life

Posamentier was born in Manhattan in New York City, the son of Austrian immigrants. He has one daughter (Lisa Joan Perlman, born in 1970), and one son (David Richard Posamentier, born in 1978). He resides in River Vale, New Jersey. He is professor emeritus of mathematics education and former dean of the School of Education at The City College of the City University of New York, where he spent over 40 years. For the next five years he was Dean of the School of Education and professor of mathematics education at Mercy University, New York. Dr. Posamentier then was invited to take on the position of Executive Director for Internationalization and Funded Programs at Long Island University, New York. After three years at LIU, he took on his current position as Distinguished Lecturer at The New York City College of Technology/City University of New York. He began his career as a mathematics teacher for six years at Theodore Roosevelt High School (Bronx, New York).

Awards and honors

In 1989, Posamentier was made an Honorary Fellow at the London South Bank University (London, England). In recognition of his outstanding teaching, the City College Alumni Association named him Educator of the Year in 1994, and in 2009 New York City had the day, May 1, 1994, named in his honor by the President of the New York City Council. In 1994, he was also awarded the Grand Medal of Honor from the Republic of Austria,^{[ citation needed]} and in 1999, upon approval of Parliament, the President of the Republic of Austria awarded him the title of University Professor of Austria. In 2003 he was awarded the title of Ehrenbürger fellowship of the Vienna University of Technology, and in 2004 was awarded the Austrian Cross of Honor for Science and Art, 1st class ^[4] from the President of the Republic of Austria. In 2005 he was inducted into the Hunter College Alumni Hall of Fame, and in 2006 he was awarded the prestigious Townsend Harris Medal by the City College Alumni Association. In 2009 he was inducted into the New York State Mathematics Educators Hall of Fame, and also that year he was Awarded the Christian Peter Beuth Prize in Berlin, Germany. ^[2] In 2017 he was awarded Summa Cum Laude nemine discrepante from the Fundacion Sebastian, A. C. in Mexico City.

Publications

Dr. Posamentier is the editor of the book series, Problem Solving in Mathematics and Beyond, which demonstrates the power and beauty of mathematics through clever problem-solving experiences. He has also authored or co-authored over 80 books, ^[5] including:
