Inclusion of the universal design for learning (UDL) model as a guiding set of principles for online curriculum development in higher education is discussed. Fundamentally, UDL provides the student with multiple means of accessing the course based on three overarching principles: presentation; action and expression; and engagement and interaction. Guidelines are also provided for incorporating UDL into an online curriculum for teaching both general and diverse populations including students with disabilities.Is one of the better pieces I've seen on the issues of making online courses accessible. They only miss in not stating that all online courses must be accessible even if the instructor is unaware of any students in the class with a disability. They still reference the Disability Services Office -- which is appropriate -- but don't explicitly state that all online courses need to be accessible as has been OCR position on this matter, as I've written before.
Looking for specific guidance for designing accessible online courses using UDL? This article is a good place to start.
