Ohio Center for Equity in Mathematics and Science

Welcome to the OHIO Center for Equity in Mathematics and Science website. OCEMS is committed to strengthening collaboration, coordination, and communication among Patton College of Education faculty, Ohio University faculty in other colleges, PreK-16 educators and administrators in the SouthEast Ohio region and beyond, and other important stakeholders including faculty at other institutions. This work supports The Patton College of Education and Ohio University missions.

Director Dr. Courtney Koestler brings expertise and focus on issues of diversity, equity, and justice in teaching and teacher education, in early childhood education, elementary education, teacher education, and mathematics education. Dr. Koestler is a former K-8 public school teacher and has taught in culturally, linguistically, economically diverse schools located in rural, suburban, and urban communities. Dr. Koestler had been both a classroom teacher (grades 2, 4, 5, and 8) and has also worked as a mathematics coach. For over a decade Dr. Koestler has been a university-based teacher educator at the University of Wisconsin-Madison, the University of Arizona, and now at Ohio University as Director of OCEMS.

Dr. Koestler is actively involved with mathematics education and teacher education organizations, such as the Association of Mathematics Teacher Educators (AMTE) and the National Council of Teachers of Mathematics (NCTM). Dr. Koestler is also very involved in regional and state-level work. Dr. Koestler is the Vice President- Elementary of the Ohio Council of Teachers of Mathematics (OCTM), and is the Advisor for the Ohio University Council of Teachers of Mathematics
