Why Accessibility?Accessible… Content design improves learning for all users Interface usability improves for all users Page code is more portable, semantically rich (i.e., minable), &
lighter It’s [probably] the law
“It’s the right thing to do”
![Page 3: The Accessibility of Course Management Systems: Can You Read This If You’re Blind?](https://reader038.vdocument.in/reader038/viewer/2022103006/56812b07550346895d8ee789/html5/thumbnails/3.jpg)
Four Main Categories of Disability Accommodation
Visual (blindness, low-vision, color-blindness) Motor (traumatic injuries, congenital disorders and diseases) Auditory (full or partial hearing loss) Cognitive (attention deficits, learning disabilities in reading,
comprehension, memory, problem-solving, math or graphic interpretation)

Visual Impairments Screen readers can render
well formatted pages well See an example at

D2L User-Vendor Collaborations First accessibility audits by OSU Web Accessibility Center
Spring 2005 and 2006 Active collaboration begun June 2006 Accessibility panel at D2L 2006 Users Conference (UC06) Current round of evaluations on pre-production version (v. 8.2)
Looking at specific interfaces and widgets/tools Evaluations by “expert users”Using matrix of UIUC “best practices” (http://cita.disability.uiuc.edu/html-best-
practices/) Semi-monthly teleconferences (http://cita.disability.uiuc.edu/collaborate/desiretolearn/) Collaborations using Google Apps for document sharing (http://www.google.com/a/)

Current Status and the Future Improvements between versions 7.4 and 8.1
More consistency in markup of graphics (part of D2L build process)Some improvements in naming conventions of graphics and tools
The future: Usability testing (if improvements merit)

Conclusions All have many problems All say they are trying Much still depends on the accessibility of the content
developed by facultyWe need accessibility checks as material is uploaded
Keep asking questions of the vendors Get involved in the product selection The Big Question: Open Source or Commercial?
