Jerilynn Lepak

Assistant Professor
Department of Mathematics
Seattle Pacific University
United States of America


Education: BA, Winona State University, 1996; PhD, Michigan State University, 2013. At SPU since 2015. Dr. Jerilynn Lepak is responsible for elementary mathematics education, and as such bridges both the Math Department and the School of Education. She was previously an assistant professor of mathematics education in the mathematics department at the University of Central Arkansas. There she gained teaching experience with both elementary- and middle-level math, both methods and content. Prior to embarking on her formal graduate studies in mathematics education, she had a decade of experience teaching middle school and high school mathematics.  How does their pedagogical content knowledge impact their reactions to students’ solutions to problems? She also held a post-doctoral research fellowship at UC Berkeley, where she developed assessments to measure student learning in algebra, using them to identify the most effective pedagogical approaches. Dr. Lepak has been a Christian believer since her college days. Her faith has infused every part of her life, from parenting to teaching prospective teachers, to conducting research in education.

Research Interest

Dr. Lepak’s research focuses on prospective teachers’ conceptions of the content knowledge required to teach representations, operations, and conceptual and procedural understanding of rational numbers.
