She has worked in mathematics education for 30 years, both in schools and at EDC, where her work has focused largely on K–12 mathematics curriculum development and mathematics teacher professional development. Currently, her work focuses on helping mathematics teachers adopt and successfully implement formative assessment practices, and on supporting teachers’ understanding and use of the CCSS Standards for Mathematical Practice. As a member of the NSF-funded project, Formative Assessment in Mathematics Classrooms: Engaging Teachers and Students (FACETS), she was a lead facilitator for several of the participating districts.
Creighton has written print and online materials for numerous clients, including the international Department of Defense schools, the Columbus, Ohio public schools, the National Board of Professional Teaching Standards, Everyday Learning publishers, the PBS TeacherLine project, the Massachusetts Dept. of Education, and the E-Learning for Educators project funded by the U.S. Dept. of Education. She has also served as the director of the MathScape Curriculum Center, a national center that supported the implementation of the NSF-funded mathematics curriculum MathScape developed at EDC, for which she was also one of the writers, and has led numerous teacher professional development opportunities for middle and high school teachers on the teaching and learning of mathematics. Prior to coming to EDC, she taught middle school and high school mathematics for a number of years in Portland and Saco, Maine and in Brookline, Massachusetts. She received a B.A. mathematics and a M.Ed. in Secondary Education, with a concentration in curriculum, both from the University of New Hampshire. She currently lives in western Massachusetts with her husband, her two teenagers, and the world’s softest dog.
