Courtney Koestler is currently the Director of the OHIO Center for Equity in Mathematics and Science (OCEMS) and an Associate Professor of Instruction in the Patton College of Education at Ohio University. Courtney earned a BS in Elementary Education with a concentration in mathematics at Ohio University, an MA in Teaching at George Mason University, and a Ph.D. in Curriculum and Instruction at the University of Wisconsin. Courtney began teaching in public elementary and middle schools as a classroom teacher in 1998, went on to serve as a K-5 math coach, and then started working as a university-based teacher educator and researcher.

 In addition to now teaching diversity and mathematics methods courses in an early childhood-elementary education program and graduate action research courses, Courtney spends time in classrooms alongside teacher colleagues teaching children and out in communities working with families. These experiences continue to guide Courtney in understanding teaching and learning as a equity- and justice-oriented endeavor.
