My research program is focused on understanding how people make sense of the information around them and why our behavior can vary so dramatically across different contexts. I often focus on quantitative information, such as number and proportion. How do children reason about “how much” and “how many”? How do people combine amounts to think about proportions? How does the development of these skills support our ability to learn formal mathematics?
