  • My research is focused on answering the question: “How do children acquire mathematical understanding?” The aim of my research is to identify the cognitive and educational bases of children's mathematical reasoning. Specifically, I am interested in basic number abilities/disabilities and the conceptual changes that occur as children acquire mathematical competence. I am especially interested in identifying different patterns of mathematical understanding and the ways in which these patterns change or remain stable over time. In association with colleagues, I am currently conducting research on: (1) individual differences in students’ acquisition of algebraic ability; (2) using interactive assessment to evaluate children's mathematical learning potential in rational number and algebra; (3) the relationships between the development of mathematical, language and general cognitive concepts across the primary-school years; (4) individual differences in the development of primary-school aged children's number concepts. In addition, I run a Dyscalculia diagnostic testing centre. The tests used are based on our extensive research into young children’s number understanding from Pre-prep through the primary years. Our results have identified some important markers of number cognition which are independent of instructional competencies and provide diagnostic indicators of Dyscalculia.
