Universal design for learning (UDL) incorporates accessibility, usability, and effective teaching methods into curriculum to allow all students to learn. UDL provides multiple means of presentation, expression, and engagement through varied content formats, alternative assignments, and different participation options. This framework originated from universal design in architecture and aims to design education from the start for people of all abilities. UDL supports diversity in classrooms by addressing varied student needs through a flexible approach rather than a one-size-fits-all model.
