Meet the Robertson Team


Beverly Caswell, PhD / Program Director

Beverly Caswell works collaboratively with educators to design inquiry-based learning environments for children that promote equity and a deeper understanding of mathematics and science concepts. She is an Associate Member of the Centre for Urban Schooling at OISE and one of the founding coordinators of OISE’s Inner City Option, Initial Teacher Education. Bev completed her doctoral research on equity in mathematics and is dedicated to working with students typically underserved by the educational system. Bev has 10 years experience as an elementary school classroom teacher, six years experience in the Initial Teacher Education program at OISE, and has been with the Robertson Program since 2010. She is currently involved in a mathematics professional development project in collaboration with educators from the Rainy River District School Board and the Seven Generations Education Institute.

Joan Moss, PhD / Professor Emerita, University of Toronto

Joan Moss is an Associate Professor Emerita in the Department of Applied Psychology and Human Development and at the Jackman Institute of Child Study at OISE/UT. Her research has focussed on the design of developmentally-based curricula highlighting areas of mathematics that are traditionally challenging for students.  Her curriculum for rational number was published by McGraw Hill as part of a US mathematics textbook series. Since 2011, Joan has been co-principal investigator of the Math for Young Children (M4YC) where her research has been focussed on the teaching and learning of spatial reasoning and geometry in early years.  Joan holds a special role within the Robertson Program by sharing her expertise in mathematics teaching and learning, and spearheading the research components of the program. Most recently, she has collaborated with the Robertson Program to expand the M4YC initiative to include collaborations with First Nations communities and the Rainy River District School Board.
