The goal of education in the 21st century is not simply the mastery of knowledge. It is the mastery of learning. Education should help turn novice learners into expert learners—individuals who know how to learn, who want to learn, and who, in their own highly individual ways, are well prepared for a lifetime of learning.
Universal Design for Learning (UDL) is an approach that addresses and redresses the primary barrier to making expert learners of all students: inflexible, one-size-fits-all curricula that raise unintentional barriers to learning. Learners with disabilities are most vulnerable to such barriers, but many students without disabilities also find that curricula are poorly designed to meet their learning needs.
