Universal design is an approach to designing products and environments to be usable by people of all abilities, to the greatest extent possible, without the need for adaptation or specialized design. It involves considering people of all ages and abilities during the design process to ensure accessibility and usability. Some key principles of universal design include providing multiple means of representation, expression and engagement to support learning by students with diverse backgrounds, abilities and learning styles. When implemented well in classrooms, universal design can benefit both teachers and students by making learning more inclusive and exciting for all.
