Since 2009, Lisa Ginet, Ed.D. has served as a member of the Erikson Institute’s Early Math Collaborative, which was launched in 2007 to transform early math teaching and learning. During her tenure as assistant director of facilitation for the Early Math Collaborative, Dr. Ginet has thought a lot about the essence of foundational math, as well as ways to foster mathematical thinking in children, make math engaging and enjoyable for adults and create authentic mathematical environments in early childhood classrooms. Prior to her work at the Erikson Institute, she spent more than a quarter century as an educator, working as a classroom teacher, child care provider, parent educator, home visitor, teacher trainer and adjunct instructor in settings that ranged from child care centers and elementary and middle schools to community colleges and universities. She earned her B.A. in psychology and social relations from Harvard and Radcliffe Colleges and her M.S.E. in early childhood and elementary education from the Bank Street College of Education. In 2010, she received her Ed.D. in early childhood education from Concordia University Chicago. Her doctoral dissertation explored the ways that teacher attitudes and beliefs about mathematics influence classroom practices in early childhood settings.
