Universal Design of Instruction
"The universal design of instruction (UDI) is gaining increased attention and application by educational researchers and practitioners at K-12 and postsecondary levels. UDI means that, rather than designing for the average student, you design instruction for students who potentially have broad ranges with respect to ability, disability, age, reading level, learning style, native language, race, ethnicity, and other characteristics. UDI can be applied to all aspects of instruction, including class climate, interaction, physical environments and products, delivery methods, information resources and technology, feedback, and assessment."
