Helena Osana is a Professor at Concordia University in Montreal, Canada, where she conducts research at the intersection of mathematics development, mathematical cognition, and educational psychology. Her work focuses on children’s mathematical thinking and identifies cognitive, representational, and instructional factors that support learning. Specifically, she investigates how external representations—including images, diagrams, and concrete materials—shape children’s problem solving, reasoning, and conceptual development. Dr. Osana collaborates closely with educators, aiming to translate her research into practical applications within teacher education programs. Current projects include examining how children conceptualize units and investigate the types of visual representations that support their ability to treat collections as countable wholes. Dr. Osana is committed to enhancing early mathematics education through research-practice partnerships in schools.
