Alfred Posamentier

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.

Alfred S. Posamentier

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]

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 College, 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.
