Read this one-page "Introduction to Web Accessibility" from the World Wide Web Consortium (W3C). The W3C is an international community that develops open standards to ensure the long-term growth of the Web.
Layered atop W3C's overview of web accessibility, the University of Michigan has additional obligations. From the U-M Web Accessibility Website:
"Both the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1991 prohibit colleges and universities from discriminating against students, faculty, and staff with disabilities. Case law is putting the spotlight on our University’s websites and videos. More importantly, web accessibility is the right thing to do: people with disabilities are attempting to read your content. They have a right to participate fully in our online community."
If you are working on an online survey, you are working on a website.
You will likely never know if a person in your subject pool has a disability. It is your ethical obligation to design, to the best of your abilities, surveys that are universally accessible.
Qualtrics does many things right when it comes to accessibility -- that's one reason why so many R1 institutions use it as their primary survey-building tool. That said, as MSU puts it, "many aspects of the accessibility of surveys depend on choices made by survey creators," like you.
Read the following two webpages, each should take 5-10 minutes:
Michigan State University's Guidelines for Survey Creators
University of Colorado's Qualtrics Accessibility
You should probably also read WebAIM's Alternative Text article if your real survey, or anything else you post to the web, includes images.
Complete and submit this online worksheet: "Improving Qualtrics Accessibility."
Return to your Practice Survey 2 and make the following changes:
Change the survey title to something more appropriate.
Add appropriate alt-text to the three images in the Experiment block. More on alt-text...
Once you've successfully completed the tasks, you're ready to wrap-up this online module.
