Cristina Carrazza

PhD Student

I am interested in how children construct knowledge from their learning experiences. What malleable factors in the early learning environment influence understanding and future academic achievement?  Currently, I am assessing how small variations in counting practice affect children’s development of number concepts. 

Marjorie Schaeffer

PhD Student

I am interested in the role parents and teachers play in the development of math knowledge and  attitudes. I am currently exploring the mechanism by which parents' attitudes and beliefs influence children's math attitudes and achievement. 

Julianne Herts

Phd Student

I am interested in the way that classroom instruction interacts with students’ knowledge and attitudes about math to influence learning outcomes. Currently, I am investigating the effects of factors such as anxiety, gender, and socio-economic status on math learning and test performance.

Jalisha Braxton

PhD Student

I am interested in how children's attitudes about math influence their math learning and performance. I am also interested in the role of executive functions in early math learning. I am currently exploring how anxiety, uncertainty, and stereotypes about math impact the decisions children make when learning.

Maddy Oswald

PhD Student

I am interested in how children learn their first number words. I'm currently exploring how syntactic cues facilitate the mapping of quantity words onto number concepts and how further language experience strengthens these concepts.

Nancy Pantoja

PhD Student

I am interested in how interactions with parents and teachers affect children's math attitudes and math performance. Currently, I am exploring how parents' early number talk and math attitudes affect children's math performance, and how these effects differ in contexts of socioeconomic status.


Mia Velazquez

PhD Student

I am broadly interested in the underlying cognitive mechanisms of mathematical learning, and, more specifically, the relationship between spatial and numerical cognitive development. I am currently exploring how children and adults mentally represent sets of objects, and how spatial cues support numerical estimation.

Jacob Butts

PhD Student

My research explores conceptual development with a focus on mathematical symbols and notations. Specifically, I am interested in how linguistic input and spatial representations impact children's understanding of mathematical concepts. Through this research, I hope to better understand the basic cognitive processes that drive learning and identify mechanisms to close achievement gaps in mathematics.
