Many people think of mathematics as something that you “do” by following a teacher’s step-by-step guidance about how to solve problems. My work in discourse counters this perspective and instead is aimed at supporting teachers to empower students to grapple with the mathematics and engage with the discipline in ways similar to how mathematicians go about their work. Rather than asking myself whether or not I think students can learn any given math concept, I guide my work by identifying ways how I can get students to think about and ultimately understand them through oral and written discourse.

Students frequently write in math class, yet elementary teachers have had limited guidance about what and why they should have their students write. Thus, students may “write about math” rather than “write mathematically.” I currently am focused on developing and researching ideas about written discourse that aims to use writing to leverage the learning of mathematics. I directed a project funded by the National Science Foundation that brought together the Elementary Mathematical Writing Task Force, a group of university- and district-based educators with collective expertise in mathematics education, writing education, mathematics, English language learners, special education, gifted education, assessment, and curriculum. You can access the white paper outlining their recommendations about the types of and purposes for mathematical writing in the elementary grades and other resources published by our team here.

Curriculum resources also are major tools that can support the implementation of oral and written discourse. Prior to my current appointment, I worked extensively to develop and research the efficacy of advanced mathematics curriculum for elementary students. I served as Co-Principal Investigator for Project M^2: Mentoring Young Mathematicians for 6 years, a National Science Foundation research grant that developed challenging geometry and measurement units for kindergarten through Grade 2 students. As part of this work, I conceptualized the Student Mathematician Discourse Model that supported students’ mathematical communication that results in writing. Prior to that, I worked on Project M^3: Mentoring Mathematical Minds, a series developed for mathematically promising students in Grades 3 through 5 from which Project M^2 was conceived.
