Rachael M. Welder received her Ph.D. in mathematics education from Montana State University in 2007, after obtaining undergraduate and master’s degrees in mathematics. She has held tenured and tenure-track mathematics education faculty positions at Hunter College–The City University of New York (2007-2015) and Western Washington University (2015-2019). She is currently serving as a (Post-Doctoral) Research Associate in the Department of Teaching, Learning & Culture at Texas A&M University, working with Dr. Roger Evans Howe, Professor Emeritus of Mathematics at Yale University and Distinguished Professor and Curtis D. Robert Endowed Chair in Mathematics Education at Texas A&M University.
Dr. Welder has been teaching undergraduate and graduate mathematics content and methods courses for prospective and inservice teachers and mathematics courses for non-teaching majors since 2001. She is most interested in content courses for prospective elementary and middle grades (K-8) teachers of mathematics. She is currently working to develop curriculum and a sustainable model for mentoring doctoral students as they transition to teaching such courses for teachers at Texas A&M University.
Dr. Welder’s research focuses on the work of mathematics teacher educators, particularly in regard 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. Most recently, she served as a guest editor producing a two-volume Special Issue of The Mathematics Enthusiast on “Supporting Mathematics Teacher Educators’ Knowledge and Practices for Teaching Content to Prospective (Grade K-8) Teachers” published in June 2020.
