Elena Silla
Elena Silla is a Ph.D. in Education student specializing in the Learning Sciences in the School of Education at the University of Delaware. Her research interests include mathematical cognition and problem-solving skills such as flexibility in strategy use. She is also interested in learning how small changes in instruction can promote student learning in math classrooms.
Elena earned her B.A. in Psychology with minors in Education, Schooling, and Society and Business Economics from the University of Notre Dame. She then taught fourth grade in Oakland, CA for two years while earning her M.Ed. from Notre Dame through their Alliance for Catholic Education (ACE) program. She also worked as a research specialist and lab manager at the University of Wisconsin-Madison in the Cognitive Development and Communications Lab.
