Deborah Rosenfeld

senior research associate

Dr. Deborah Rosenfeld, researcher at EDC|CCT, has a deep knowledge of early childhood mathematics through her experiences teaching young children, studying their teachers’ knowledge and beliefs about early childhood mathematics, and working with teachers to develop knowledge of mathematical development. Prior to joining CCT, she was a classroom teacher for grades 1, 4, and 8. She joined EDC as a curriculum writer for the NSF-funded Think Math elementary math program, and has since developed professional development and conducted research on the implementation of reform-based elementary math curricula and its impact on student outcomes. She now works as a researcher on the Ready to Learn project, a federal research and development program using transmedia to improve the math and literacy skills of young children.

Dr. Rosenfeld received her A.B. in Psychology from Harvard College, Ed.M. in Human Development from the Harvard Graduate School of Education, and her Ph.D. in Educational Psychology, with a focus on early childhood mathematics, from Teacher’s College, Columbia University, studying under the guidance of Dr. Herb Ginsburg. Her dissertation focused on the confidence and competence of prospective early childhood teachers to teach math, and found that viewing videos of preschool children being interviewed about their math knowledge can enhance confidence in teaching math and help teachers to see the potential and challenges of teaching math to these children.
