Designing for Accessibility and Usability in Online Courses
Lisa RichardsonThe University of Southern Mississippi
Do You Really Know Your Students?
Over 4% of enrolled undergraduate and graduate students nationwide have disabilities requiring some sort of accommodation (U.S. Census Bureau, 2006)According to the National Center for Educational Statistics, 95% of colleges and universities surveyed reported that they used websites to deliver distance education courses, yet only 18% reported that they followed accessibility guidelines to a major extent (Waits & Lewis, 2003). Given that navigating an online course can be difficult for the average student, designing courses with accessibility in mind really means improving usability for all students.
What is Universal Design?Ron Mace – coiner of the term “universal design;” architect with polio who advocated for “barrier-free” design, was also wheelchair-bound“Universal design is the the design of products and environments to be usable by all people, to the fullest extent possible, without the need for adaptation or specialized design.” –Ron Mace (Center for Universal Design, n.d.)
What is Web Accessibility?
The law.Section 508: 1998 amendment to the Rehabilitation Act that requires federal agencies to make their electronic and information technologies accessible to people with disabilities (Access Board, n.d.)Designed to eliminate barriers to the effective use of technologyApplicable to colleges and universities as recipients of Title IV financial aid funding and via Section 504, which prohibits discrimination in education against students with disabilities
What is Usability?
“That quality of a system that makes it easy to learn, easy to use, and encourages the user to regard the system as a help in getting the job done.” (Georgetown University Information Services, n.d.)
Does it Really Matter??When a student must wade through difficult navigation and unclear sequencing to use your course site, you increase their cognitive loadThis means that they will need to use more valuable brainpower figuring out your site with little left for learning your contentThis is based on Sweller’s (1988) cognitive load theory, and it’s the reason I stress clean, universal design as a method for improving learning outcomes (aside from the legal obligation)

AccessIT’s Design Tips
Provide text alternatives for visual content (the ALT function)Caption or provide text alternatives for audio contentAvoid using color to convey important info
Use a cascading style sheet (.css) insteadUse relative (rather than absolute) units
75% vs 400x680 pixelsSmall, medium, large font sizes instead of 12, 14, 18 pt
Provide a clear, simple design (AccessIT, 2002)
Before
You Design That Course Site, Ask Yourself:
Does this course belong online?Requirement or elective?Foundation course for major?
What are the course objectives?What do you want students to learn?How is the topic best delivered F2F?

Judicious selection of “cool stuff”Does this item require a high speed connection?Will this slow down the overall loading of the page?Can I deliver this content in another manner?
Accessibility & Usability
Remember: good design addresses the needs of all possible users, without specifying “who uses what.”The implementation of universal design means that you would test your site using tools such as:
IDS Caption for .wmvALT tags – descriptions of graphic elements on the web pageVarious assistive technologies available for free from The Trace Center at the University of WisconsinThe Web Accessibility Toolbar from AIM
Testing Accessibility & UsabilityHeuristics are methods that use trial and error to solve problems (Oxford Dictionary & Thesaurus, 1996)Heuristic evaluation
Evaluating sites for possible errors in user interface designThrough site statistics, assessment resultsUtility, learnability, efficiency, retainability, error messaging, satisfaction (Nielsen, 1994)

Conclusion
Implementing universal design in your online courses ensures that you are meeting the legal requirements of Sections 504 and 508, and more importantly, the needs of as many of your students as possible. The tips and tools listed here are not hard to use, and help is often readily available. If you need help or support – just e-mail me at doktadivah(at)gmail.com and I’ll be glad to assist.
