The Accessibility of Course Management Systems: Can You Read This If You’re Blind? Joe Wheaton, The Ohio State University Ken Petri, The Ohio State University Alan Foley, The University of Wisconsin-Madison Mike Elledge, Michigan State University Kostas Yfantis, The University of Illinois-Champaign/Urbana
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”
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 http://www.doit.wisc.edu/accessibility/video/intro.asp
Motor Impairment • A famous scientist at your university has ALS and is unable to use the mouse • He navigates the web with the special software that activates the keyboard
Auditory Impairment • A student researching famous speeches in American history • Student locates site with only audio clips of many speeches • Alternately, the student finds a great speech that is captioned
Cognitive Disability • Professor who struggles with reading comprehension understands much better through listening • Professor listens to websites through a screen reader like Kurzweil

WebCT Kostas Yfanis
WebCT Vista(Blackboard Enterprise Vista) • UIUC’s Flagship Learning Management System • 1,100 courses • 31,780 unique students • Accessibility Partnership • CITES Educational Technologies • http://www.cites.uiuc.edu/edtech • Illinois Center for Instructional Technology Accessibility • http://www.cita.uiuc.edu/
Existing Challenges Pop-up windows Java applets Missing headers & image labels Others:http://www.cita.uiuc.edu/collaborate/webct/problems.php Improvements Heading structure Added alt text for images Expanded labels for form controls Language definitions Accessibility Issues
A Proactive Approach • Work with your accessibility team • Collaborate with other institutions • Do the versions match? • Can you involve the software developers and quality assurance team of the vendor? • If you use WebCT, then join our group • http://www.cita.uiuc.edu/collaborate/webct/person.php
Desire To Learn (D2L) Joe Wheaton and Ken Petri
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/)
Facilitating Remote Collaboration Functional testing using UIUC “best practices” matrix on Google Apps
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 faculty • We 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?
