Dr. Rachael M. Welder received her Ph.D. in mathematics education from Montana State University in 2007 and has both her undergraduate and master’s degrees in mathematics. After completing her Ph.D., she spent 8 years in Manhattan where she earned tenure as an Associate Professor of Mathematics Education at Hunter College, The City University of New York. In 2015, she moved to the west coast for a change of pace and began the position she currently holds in the Department of Mathematics at Western Washington University. She teaches content and methods courses for prospective elementary and middle school teachers and mathematics courses for non-teaching majors.

Dr. Welder’s research focuses on the work of mathematics teacher educators, particularly in regards to the ways in which they can facilitate prospective K-8 teachers’ development of mathematical knowledge for teaching. She is currently involved in multiple, cross-institutional efforts to (a) examine the design and implementation of tasks in mathematics courses for K-8 teachers, (b) conceptualize the knowledge needed by mathematics teacher educators who teach such courses, and (c) pursue innovations for preparing and supporting the work of these mathematics teacher educators. She is currently serving as a guest editor for the Mathematics Enthusiast Journal where she is co-developing the special issue: “Supporting Mathematics Teacher Educators’ Knowledge and Practices for Teaching Content to Prospective (Grade K-8) Teachers.”
