UDL stands for Universal Design for Learning. Visit the National Center for Universal Design for Learning. Universal is not uniform but encompasses enough variation in instruction to reach diverse learners. UDL harnesses the power of individual differences in experience, interest, engagement, perception, processing, responses and expression. UDL adjusts support for optimal engagement and learning. UDL means you don't have to "dumb down the curriculum" because UDL meets the students' needs with just-in-time help, text aloud, vocabulary support, ESL support, and multiple representations covering all of the learning pathways. UDL is defined in the US Higher Education Opportunity Act of 2008, Sec. 103 (24).
NIMAS stands for National Instructional Materials Accessibility Standards.
AIM stands for Accessible Instructional Materials.
