Accessibility in Online Learning Environments

Federal legislation, like the American Disabilities Act, Section 504 and Section 508 of the Rehabilitation Act of 1973, outlines the requirements for federal agencies to accommodate people of all abilities. For faculty, it is important to understand how these civil rights laws affect higher education and impact university services. At the course level, these laws can affect how content is delivered in the traditional, hybrid or online class.

Section 504

Section 504 of the Rehabilitation Act of 1973 prohibits discrimination of people with disabilities when attending any organization or institution that receives federal funding. This means that students of all abilities have an equal right to attend classes or programs that are physically or electronically offered on campus.

Section 508 (Student Accessibility)

Section 508 is the portion of the Rehabilitation Act of 1973 that addresses the need for Federal Agencies, like the University of North Texas at Dallas, to make electronic information accessible to people with disabilities. Section 508 most often applies to web accessibility, but also includes web services offered by the university such as course management systems or electronic library resources

American with Disabilities Act (ADA)

The 1990 Americans with Disabilities Act (ADA) requires that U.S. programs and services be accessible to individuals with disabilities. There are a total of 11 laws that protect persons with disabilities. A 1996 Department of Justice ruling makes it clear that ADA accessibility requirements apply to Internet resources. An individual with a disability is defined by the ADA as a person who has a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment. The ADA does not specifically name all of the impairments that are covered.

Section 508 addresses the accessibility of all course materials and media elements and applies to the design and development of online environments. All distance education courses offered by UNT Dallas are required to be in compliance with the Americans with Disabilities Act (ADA), and all university web sites should also be in compliance with Section 508 of the Rehabilitation Act.

Instructors should be familiar with the Americans with “Disability Act”, Section 504 and Section 508 requirements and use resources to avoid violations and be in compliance. The Office of Distance Learning and Instructional Technology can assist and guide instructors with the creation of accessible online courses and material for the online environment.

Publisher Accessibility Information

Below are links to major publishers with information on the accessibility of their online content.

In addition to technical accessibility, Universal Design for Learning is an educational framework based on research in the learning sciences that guides the development of flexible learning environments that can accommodate individual learning differences. Through funding from the U.S. Department of Education, UDL-Universe was developed to serve as a one-stop portal for UDL and faculty development resources.
