From the website: "UDL is part of a larger movement of universal design, which works to increase access for all through designs that—from the beginning—consider needs of diverse people, not just adapting when a situation requires it. For instructors, UDL means designing your course with accessibility in mind—regardless of whether you’ve been approached by a student who may “require” such adjustments."
This website walks educators through how to make an all-inclusive course that can be used by all students, with or without a disability, from the syllabus to assessments and pedagogy.
