My general research interests are in teaching and learning mathematics. Specifically, I study issues of cognitive development of mathematical concepts, and often focus on the concept of number. I am particularly interested in the ways the concept of number is understood and developed from very early on in life until the end of high school and adult living. Also, my research focuses on the ways in which we can intervene didactically very early on from to enhance learning mathematical concepts.
