Universal Design for Learning (UDL) assures that online courses are accessible to everyone, including people who learn differently than others. Assuring that all students can take advantage of a course’s educational material is not only fair, it represents one of HotChalk’s core tenets: “Every mind matters.”
Becoming familiar with concepts related to accessibility is an important first step in creating courses available to all types of learners. The following glossaries present key ideas and provide useful vocabulary for talking about disabilities and how to accommodate them:
What follows reiterates some of the most important ideas from a course on UDL provided by Instructure, the makers of the Learning Management System (LMS), Canvas. It also aims to engender collaboration among the members of HotChalk’s Learning Design Team and beyond. By sharing our knowledge of accessible design, and by helping to make UDL an integral part of instructional design practice, we can not only respect the legal obligations of the Americans with Disabilities Act (ADA), but can also take steps towards meeting our ethical obligation to make our services available to all students. Moreover, even in the absence of disability, accessibility is good pedagogy, since accessible courses provide learners with a variety of ways to interact with materials, thereby increasing opportunities for student engagement.
To practice UDL, you must understand one of the basic aspects of disability itself, namely, that it is a social phenomenon. Disabilities have been (and still often are) conceived of as an individual’s inability to do something because of a physiological or psychological condition that limits activities or senses. A disability is more productively understood not as a limitation of the individual, but instead as a social issue, caused by an environment that inhibits the person who is disabled.
The social model of disability confirms that, in the right environment, many disabilities become simply differences. For example, a person who is blind cannot read a book without raised print; given a text in braille, however, many who are blind read as fast as their sighted peers. Provided with the right tools and environment, a disability can even become an advantage. Athlete, model, and advocate, Aimée Mullins is a good example of someone who has used her physical differences to excel. Although her legs were amputated soon after birth because of a genetic defect, Mullins has used prosthetics to make herself taller and faster, both significant advantages for her professional activities. As she herself argues in her TED talk, The Opportunity of Adversity, disabilities are caused by an inappropriate environment, not by an inappropriate person. Viewed as such, adversity can create opportunities for ingenuity and transformation, which is a way of looking at the world from which anyone can benefit.
Although the ADA was passed in 1990, amended in 2008, and updated in 2010, it does not currently include information about web-learning in its Standards for Accessible Design. This does not mean, however, that educators and those who provide educational opportunities (like HotChalk) are not legally obligated to make their materials accessible. As numerous recent lawsuits have demonstrated, students have an unquestionable right to accessible materials, despite the inadequacy of policies or laws.
Making content accessible depends upon appropriate practices at all strata of an institution’s hierarchy. At an institutional- or company-wide level, best practices include the following considerations:
For those of us designing and building courses, UDL has both guiding principles and basic practices, neither of which is hard to incorporate into our work. When creating online learning materials, instructional designers should strive to include in their courses:
Although creating materials that are accessible to all learners may seem daunting, much of the technology commonly used both by HotChalk and the educational industry as a whole already contain tools to facilitate the creation of accessible webpages.
One of Instructional Designers’ primary concerns should be the legibility for screen readers of the pages they create. Although most browsers have built-in screen readers, they are not generally as capable of relaying all information on a page as tools specifically created for the task, such as the widely used NonVisual Desktop Access (NVDA) screen reader. Even sophisticated tools depend upon correctly constructed pages containing meta-information easily interpreted by the screen reader.
The WAVE Accessibility Checker, a free extension for the Chrome browser, is a good way to become familiar with the way screen readers navigate a page. As the screenshot below shows, Wave identifies the elements of a page used by a screen reader, and signals problems and ambiguities. Using it as a proofreader to check both page structure and accessibility provides another means of improving the quality of our work. Designers can then go a step further by actually testing their pages using screen readers like the aforementioned NVDA.
Many modern LMSs, like Canvas, now have accessibility checkers built into them. Although they do not review pages as comprehensively as WAVE, they are an easy way to spot major accessibility problems in any page.
Once a designer understands how screen readers interact with online text, it is easier to create pages that do it well. Hierarchical organization in the development and presentation of ideas is essential to comprehensibility. Purdue University’s resource on the Four Main Components for Effective Outlines (i.e., parallelism, coordination, subordination, and division) is a good reminder of how to create logically sound outlines.
Once your material has been properly organized, there are some basic principles of UDL to keep in mind when creating documents, spreadsheets, PDFs, and webpages in general:
Using Canvas’ rich content editor correctly can help make a page screen reader friendly. Instructure’s course on UDL includes specific recommendations for taking advantage of features built into Canvas . Other good practices include the decision to:
Taking the time to observe the best practices of UDL is well worth the effort. Not only will it help students with disabilities to succeed, it will also make courses easier to understand for everyone.
