My primary research interest is children’s mathematical thinking. I’m also interested in the design of exploratory playgrounds for learning mathematics; contextually situated, culturally resonant pedagogy; and issues of education and social justice.
I'm currently working on projects focused on better understanding children's topological thinking, characterizing effective teaching in the Virgin Islands, promoting inquiry both within and beyond the classroom, and representing how teachers draw on their mathematical knowledge during instruction.

I have been conducting teaching experiments with children ages 6 and 7 in order to model the development of their intuitive and informal topological ideas. I designed a new dynamic geometry environment called Configure (at playwithshapes.com) that I use to elicit these conceptions and further support their development. To date, I have found that these children developed significant and authentic forms of geometric reasoning. It is these newly identified forms of reasoning, which I refer to as "qualitative geometry," that have implications for the teaching and learning of geometry and for research into students' mathematical reasoning.
I'm collaborating with Erin Krupa, also in the Department of Mathematical Sciences, and Jennifer Robinson in the College of Education to develop a new "enhanced" degree program leading to a bachelor of science degree in mathematics with a concentration in K-6 teaching. This program will feature transformative opportunities to learn mathematics through inquiry-oriented coursework and research experiences so that students will acquire the specialized mathematical knowledge that will prepare them to understand and navigate the challenges, complexities, and diversity of schools and classrooms.
Developing a Contextually Situated, Culturally Resonant Pedagogy
I am collaborating with faculty at the University of the Virgin Islands to develop a new secondary STEM teacher preparation program called UVI-Teach by adapting an existing, nationally recognized model. In developing this adaptation, we have found it prudent to consider the social and cultural context in which our future teachers will teach. We conducted interviews and follow-up classroom observations of high school mathematics teachers and other education stakeholders and identified eight features of pedagogy associated with effective teaching. We refer to these features as "Indicators of Culturally Resonant Practice." These indicators comprise a model of contextually situated, culturally resonant pedagogy that is informing the design of the new teacher preparation program.
I'm collaborating with faculty at the University of Nebraska at Lincoln to further develop "Distributed Biography," an online application that supports the creation, collection, compilation and display of written narratives by multiple individuals about an individual, event, location, or experience of mutual interest.
