Steven Rasmussen is an education professional with a long track record in mathematics education.  In 1971 Steve co-founded Key Curriculum Press, an innovative publisher of mathematics materials for elementary and secondary education. As Key Curriculum’s publisher for four decades, he has worked with hundreds of authors and projects to bring visionary educational ideas to tangible and usable form. He was the first editor of Discovering Geometry: An Inductive Approach, a high school geometry textbook published by Key Curriculum in 1989.

Steve has worked for two decades on software development, including The Geometer’s Sketchpad geometry software. In 1996 he founded KCP Technologies, developers of Sketchpad and Fathom, and led KCP Technologies as president and senior researcher until 2012.

In 1999, together with Springer-Verlag New York, Steve founded Key College Publishing, a publisher of undergraduate mathematics textbooks for mathematics and mathematics education. In 2008 John Wiley & Sons acquired Key College Publishing.

Steve has served as principal investigator on six National Science Foundation (NSF) projects to support teachers using technology in school geometry, to promote discovery and cooperative learning through professional development, and to develop digital tools for mathematics visualization. In his roles as publisher, researcher, advisor and corporate manager, Steve has participated in scores of other NSF-funded projects.

He is the author of Key to Fractions, Key to Decimals and Key to Percents, titles in the Key to … workbook series with over 10 million books in print and that launched Key Curriculum. McGraw Hill Education now publishes the Key to … series.

Steve has an undergraduate degree in mathematics (1976) and a Master’s degree in mathematics education (1978) from Temple University. He taught secondary mathematics for seven years in Philadelphia, Pennsylvania, and Emeryville, California.

Currently a Senior Associate at SR Education Associates, Steve works with many public and private non-profit and for-profit organizations as a board member or advisory board member and consults with companies and organizations on strategic initiatives in education and educational technology.

Steve has given hundreds of workshops and talks on mathematics teaching and technology at national and international professional meetings and has traveled and worked on projects with schools, universities and ministries of education throughout Central America and Asia.

From a Family of Educators

Steve comes from a family of educators and authors. His mother Lore was a pioneer in mathematics education reform in the 1950s and 60s at the Miquon School, where she established the country’s first “Math Lab” and developed the Miquon Math Materials, now published by Rainbow Resources.  Self-taught in mathematics, Lore served in two faculties of education and created the Learning Centers Project in the Philadelphia public schools. Steve’s father authored SRA’s Basic Reading Series when he was an elementary school principal. Steve’s brother Peter worked with Max Beberman at the University of Illinois and taught mathematics for many years.  He co-founded Key Curriculum, authored the company’s Key to Algebra books and in 1976 invented MathTiles, the world’s first algebra tiles.  The third Rasmussen brother, David, has a graduate degree in mathematics education from Harvard University and taught secondary mathematics for 34 years in Nova Scotia, Canada.
