In the 1990s, Anne Meyer, David Rose, and their colleagues at CAST introduced universal design for learning (UDL), a framework to improve teaching and learning. Based on new insights from the learning sciences and creative uses of digital technologies. UDL can help educators improve and optimize learning experiences for all individuals. In this book, Meyer and Rose, along with David Gordon, provide the first comprehensive presentations of UDL principles and practices since 2002. This new look at UDL includes contributions from CAST's research and implementation teams, as well as their collaborators in schools, universities, and research settings. This book includes new insights from research on learner differences, how and how human variability plays out in learning environments; research-based discussions of what it means to become expert at learning; first-hand accounts and exemplars of how to implement UDL at all levels and across subjects using the UDL Guidelines; dozens of original illustrations and access to videos and other online features at http://udltheorypractice.cast.org
