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.
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.
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).
