Erin Krupa is an Assistant Professor of Mathematics Education in the Department Science, Technology, Engineering, and Mathematics Education at North Carolina State University (NCSU). Her research focuses on improving the quality of mathematics teaching and learning through innovative curricular materials and professional development. Previously she was an associate professor of Mathematics Education in the Department of Mathematical Sciences at Montclair State University. She earned her Ph.D. in mathematics education at North Carolina State University (NCSU). Prior to returning for her Ph.D., Erin taught secondary mathematics at W.G. Enloe High School in Raleigh, NC. She holds a masters degree from Wake Forest University in mathematics. Erin was a Teaching Fellow at Elon University, where she earned her bachelors degree in mathematics.

Erin is interested in the design, dissemination, and effectiveness of innovative professional development for mathematics educators. She strives to provide quality professional development to enhance teachers’ instructional practice, content knowledge, and beliefs. Of particular interest to her is the impact professional development has on both curricular implementation and student mathematics achievement. Studying curricular effectiveness, Erin uses hierarchical linear modeling to examine the relationship between curriculum use and student achievement. She is interested in teachers’ implementation of instructional materials and state standards and how these influence student achievement.

Erin’s research pays close attention to the opportunity to learn students are provided within a classroom and how teachers can increase this index for all students, regardless of demographics. Her experiences working in rural, economically disadvantaged communities have been very valuable to understanding of the disparities and triumphs that occur in these communities. She enjoys working with underserved populations and strives to make quality mathematics education more equitable to all students.
