UDL IS A FRAMEWORK.
Universal Design for Learning (UDL) is a set of principles for curriculum development that give all individuals equal opportunities to learn. UDL provides a blueprint for creating instructional goals, methods, materials, and assessments that work for everyone--not a single, one-size-fits-all solution but rather flexible approaches that can be customized and adjusted for individual needs.
The UDL principles are based on the three-network model of learning that take into account the variability of all learners—including learners who were formerly relegated to “the margins” of our educational systems but now are recognized as part of the predictable spectrum of variation. These principles guide design of learning environments with a deep understanding and appreciation for individual variability.
The UDL Guidelines (2012), whose foundation includes over 800 peer reviewed research articles, provide benchmarks that guide educators in the development and implementation of UDL curriculum. These Guidelines serve as a tool with which to critique and minimize barriers inherent in curriculum as educators aim to increase opportunities to learn.
