About the authors & contributors

Our group consists of 13 mathematics educators and researchers: Rosalie DeFino, Erin Edgington, Lisa Hennessey, DeAnn Huinker, Jennifer Kosiak, Sarah Lord, Nicole Louie, Percival Matthews, Jenni McCool, Maggie McHugh, Mitchell Nathan, Ashley Schmidt, and Ana Stephens. We hold positions at the University of Wisconsin–Madison, the University of Wisconsin–La Crosse, and the University of Wisconsin–Milwaukee. Collectively, we have over 175 years of experience as classroom teachers and as mathematics teacher educators. Our research expertise spans topics including how children develop understanding of whole numbers and fractions, children’s conceptions of measurement, the development of children’s algebraic reasoning, practice-based mathematics teacher education, and teacher learning toward equity in mathematics education. Members of our group have received awards from organizations including the National Academy of Education, the National Science Foundation, the U.S. Department of Education, and the American Educational Research Association. We have served in leadership roles including President of the Wisconsin Mathematics Council, President of the Wisconsin Association of Mathematics Teacher Educators, and member of the National Council of Teachers of Mathematics Board of Directors. While our interests and perspectives are wide-ranging and diverse, we share a commitment to Wisconsin students and their right to a high-quality mathematics education that affirms their capabilities and nurtures their potential.
