Dr. Myung-Sook Koh is Professor of Special Education at Eastern Michigan University, where she prepares educators to transform cognitive potential into functional intelligence for students with intellectual and learning challenges. With decades of experience bridging urban classroom teaching and teacher education, Dr. Koh developed the Unified Development Continuum (UDC) framework to reclaim cognitive development from medicalized models and place systematic diagnostic tools directly in educators' hands. Her research focuses on transforming cognitive potential into functional intelligence for students with intellectual and learning challenges. This comprehensive framework—tested across diverse classroom settings—equips teachers with practical, research-grounded strategies for supporting young learners across all developmental domains.
