Bárbara M. Brizuela
Bárbara M. Brizuela is an American mathematics educator, and an associate professor education at Tufts University. Education and career. Brizuela was born in the United States, though raised in Argentina and Venezuela. She has an Ed.D from Harvard University where she studied under Eleanor Duckworth. Prior to that, she received a Master of Arts, General Studies in Education from Tufts and a Licenciada en Ciencias Pedagógicas and Licenciada en Psicopedagogía degrees from the Universidad de Belgrano. She was a Spencer Fellow at the Harvard Graduate School of Education from 1997 until 2000 and a Roy E.  Larsen Fellow in 1996–1997. She is one of the leaders of the Tufts Math, Science, Technology and Engineering Education graduate research program. In 2008, she received a Fulbright Fellowship. Research. Brizuela's main research focus is on mathematics education in early childhood and elementary school. She mainly studies children's learning of written mathematical representations as well as children's construction of algebraic understandings in a line of work called "Early Algebra". She is a member of the Early Algebra Project, an NSF-funded longitudinal study of the effects of introducing some algebraic concepts to children in elementary school, and  was the Principal Investigator of a study created to follow up the children of the Early Algebra study into middle and high school, also funded by the NSF. She is also involved in the Noyce Teacher Fellowship Program at Tufts and in the research effort surrounding Tufts's Poincaré Institute for Mathematics Education, an NSF NSF MSP project. Books. In 2004, her book "Mathematical Development in Young Children: Exploring Notations" was published. This book was later translated into Portuguese. In 2007, she published the book "Bringing Out the Algebraic Character of Arithmetic: From Children’s Ideas to Classroom Practice" with  her colleagues Analúcia Schliemann and David Carraher. This book was later translated into Spanish. She is also the author of "Haciendo números: Las notaciones númericas vistas desde la psicología, la didáctica la historia" (Editorial Paidós Mexicana, 2006) With Brian E. Gravel she edited "Show Me What You Know: Exploring Student Representations Across STEM Disciplines" (Teachers College Press, 2013).
