Digital Learning Program Development

Accessibility


One of the most important (and often overlooked) components of selecting good digital resources is to ensure that these resources are accessible to all students. In many districts, accessibility is an afterthought, and usually just thought simply as captioning videos. However, building and selecting tools that are accessible is a process that is intentional, involved, and complex. Accessibility comes in two forms: software accessibility which will be discussed in this unit, and assistive and adaptive hardware which will be discussed in Unit 4.

Understanding “Disability”

It’s common for the term “disability” to be misunderstood. For many, what comes to mind when you think of the term “disability” is what is commonly referred to as the “medical model” for disability - the idea that a disability is a medical condition requiring treatment or medical intervention. The Social Model of disability, by contrast, takes a different approach - that the environment is the problem and a “disability” is caused by a mismatch between a person and their environment. Under the social model, the focus is less about “treating” the disability as a medical condition (for many, “treatment” of a disability is a very controversial topic that both in perception and reality assumes that something is “broken” and needs to be “fixed”) and more about ensuring the environment and others adapt to meet the needs of the individual. Under the social model, disabilities can be considered situational (a d/Deaf person may be considered by others to be “disabled” in an environment where others cannot communicate with them, but their disability may be looked at differently at a school for the deaf) or temporary (mobility challenges related to pregnancy). Disability also exists as spectrum within three areas: physical, sensory, and neurocognitive.

A black and white diagram graphic, with black and white vector symbols representing physical disability, deaf and blindness, and neurocognitive disabilities, illustrating disability as a spectrum. Underneath the symbol of the wheelchair for physical disabilities reads a list: paraplegia, quadriplegia, spinal cord injury, spina bifida, cerebral palsy, cystic fibrosis, multiple sclerosis, muscular dystrophy, dwarfism, amputees, ehlers danlos syndrome, diabetes, & more. Underneath the sensory symbols of crossed out ear and crossed out eye read: deaf, hard of hearing, late-deafened, blind, low vision, deafblind, anosmia, aguesmia, & more. To the right, under the neurocognitive symbol of silhouette of a head with question marks inside read: autism, a.d.d., a.d.h.d., dyslexia, down syndrome, dementia, alzheimers, learning disabilities, psychological disabilities, & more.

It’s also important to realize that how we refer to people with disabilities matters. There is much controversy around person-first vs identity-first langauge. Around 20 years ago, it was seen as “respectful” to refer to a person using person-first language with a disability as a “person with X disability”. However, in more recent times there has been increasing amounts of pushback against this idea, as the social model for disability becomes increasingly common and a disability as seen as part of a core identity. Just as we refer to other characteristics of core identity using identity-first language (e.g., a Christian person; a gay person; etc.) so too has it become common for disabled people to want to use identity-first language (e.g., an “autistic person” versus a “person with autism”) as autism/deafness/blindness, etc. is a part of a person’s core identity and not a disease requiring treatment (e.g., a person with cancer).

Of course, how a person wants to be referred to, how they view their disability, and their specific individual needs for accessibility are going to be unique to an individual. While we can share generalizations in this course, there’s only one way to know how to refer to a person with a disability or how to build accessible materials - you need to talk to the people who you are serving. In unit 1, we discussed “designing with and not designing for”. In no case is this more critical than in designing for the disabled community.

Requirements for Accessible Content

Section 508 of the Rehabilitation Act of 1973 requires that “Federal agencies to make their electronic and information technology (EIT) accessible to people with disabilities”. While this definition has not extended to federally-funded agencies yet, Section 504 of this act does require that any organization receiving federal funds shall not deny benefits or face discrimination in any program because of their disability (504 plans originate from this section which are plans to support students during a temporary disability). Additionally, Title II of the Americans with Disabilities Act, which “prohibits discrimination on the basis of disability by both public and private entities, whether or not they receive Federal financial assistance” and requires:

State legislatures and courts, town meetings, police and fire departments, motor vehicle licensing, employment services, and public transportation programs. State and local governments must operate their programs so that, when viewed in their entirety, they are readily accessible to and usable by people with disabilities. They must provide programs and services in an integrated setting, unless separate or different measures are necessary to ensure equal opportunity, and must eliminate unnecessary eligibility standards or rules that deny individuals with disabilities an equal opportunity to enjoy their programs or services. State and local governments must also make reasonable modifications in policies, practices, and procedures and provide effective communication through the use of auxiliary aids and services when necessary to ensure equal access for individuals with disabilities, unless an undue burden or fundamental alteration would result.

These are the laws that mandates things like handicap ramps and braille signs, but also includes websites, parental communications, and educational resources. Additionally, for schools, the Individuals With Disabilities Education Act (IDEA) requires that students receive services such as captioning and braille translation and assistive technology devices to ensure access to the Least Restrictive Environment. Educational technology tools and digital resources used in the classroom must be able to comply with all of these laws as well as a child’s IEP, or alternative arrangements must be made. Depending on the nature of the arrangements that need to be made, the tool or assignment must be altered for all students in the event that failure to do so routinely removes the student from the Least Restrictive Environment.

While accessibility has been required, there had been no technical standard for providers to meet. However, that all changed on April 8, 2024 with the passage of a new Federal rule requiring state and local governments to meet WCAG2.1-AA standards. These standards are discussed in more detail below but create very concrete rules for governments, including public schools, to meet. Schools have two years or three years (depending on the size of their communities) to ensure that all of their content, including the content they purchase, meets this accessibility standard. There are very limited exceptions, including archived data and old social media posts. This represents a significant undertaking for governments, schools, and universities to retrofit old content to comply with this specific standard.

Other Obligations

Beyond the federal requirements, the constitution of the State of North Carolina requires that “a general and uniform system of free public schools shall be provided throughout the State, wherein equal opportunities shall be provided for all students, in accordance with the provisions of Article IX of the Constitution of North Carolina” and that “the people have a right to the privilege of education, and it is the duty of the State to guard and maintain that right.” Beyond the legal ramifications of designing or selecting inaccessible content, one could argue that as CTOs and ITFs, we have a moral obligation that if we are to leverage the power of technology as a “great equalizer”, we are obligated to select and promote tools that can be accessed by all and to not use technology as a tool that furthers inequity within our education system and denies opportunities to certain students.

Failure to Comply

The Office of Civil Rights is charged with investigating claims of violation of any of these laws and schools failing to comply can be subject to civil lawsuits or sanctions. Numerous schools are sued yearly for failure to create school and classroom websites with accessible content. Several years ago, the University of California at Berkeley released video lectures and course content free of charge. The course content was released through the edX MOOC platform and through iTunes-U. Because the videos weren’t captioned, the school faced a lawsuit over ADA violations. As a result of the time and expense to bring these videos into compliance, they removed all of their old content from the web. Some have argued that this robbed the majority of people with high-quality content based on the needs of a small audience, while others have argued that this audience was being denied access to these publicly-funded resources because of their disability.

Creating Accessible Content

As stated earlier, creating content which is accessible to all is a very intentional and very difficult process. Everything from content layout to font choice to word choice to the use of tools is subject to consideration.

The UK accessibility office has put together a series of accessibility guideline posters and made them available on GitHub to support designers and content creators as they create content.

General Guidance

The WCAG 2.1 Guidelines are a starting point created by the World Wide Web Consortium to set standards for how content on the web should be formatted to be accessible. WCAG standards are divided into three levels based on the level of modification required to be compliant, ranging from “A” which is the least strict to “AAA” which is the most strict. All public sites in Europe are required to be AA-compliant, and that is a recommended best practice for sites in USA public schools also. While tailored to the web, some of the guidance in WCAG2.1-AA is generally recommended for all electronic media. The WebAIM project out of the Center for Persons with Disabilities at Utah State University has a thorough set of tutorials for creating accessible content. You should read the entire thing, but a few of the key points are listed below.

  • Text should be left justified. If text needs to be right justified for visual reasons, that is acceptable as it is acceptable to center single lines of text. Do not full-justify text. Ensure adequate margins and spacing around and within text boxes and make fonts as large as is practical.
  • Videos should be captioned in a time-synced way, meaning that the captions should follow along with the video. YouTube’s auto-captioning features is a good start, but it’s insufficient - captions should be accurate and should also include text descriptions of any audio cues that aren’t speech (such as background noise which is relevant to the video content).
  • All links should be descriptive in nature. Screen readers are able to present users with a list of links on the page for easier navigation. While it’s tempting to use text like “click here” as a link, it doesn’t convey sufficient detail out of context. Therefore links should read something like “click here to access this file” or “Public School District Home”.
  • A page should be able to be zoomed in with minimal loss of functionality and should be able to be navigated by keyboard so that users of switching devices in lieu of a mouse can navigate.
  • All images should contain alternative text. The text should not convey the meaning of the image and not simply state what the image is. For example, your school logo should have alt text “XYZ School, Home of the Bulldogs” and not “School Logo”. For more information about alt text, check out this article from Moz on AltText and this primer on AltText from WebAIM.
  • To that end, using text in images is discouraged since screen readers can’t parse it, and won’t be able to read the image.
  • Avoid low-contrast backgrounds and text (think “black text on navy background”). WCAG recommends a contrast ratio of at least 4.5:1 for all media and 3:1 for any text larger than 18 point or bolded and 14 point. A contrast checker on the web can help with this - put in two HTML color codes and it will tell you if the contrast ratio is correct.
  • Do not only use color to convey meaning in content and in visual elements. Use elements such as text, shape, and size to support the use of color in visual elements.
  • Words that are unusual or are new abbreviations for words should be explicitly linked or explained inline. If pronunciation is critical to understanding a word, it should be included as well.

While WCAG is currently not a requirement, in July of 2023, the Federal Office of Civil Rights proposed a rule requiring WCAG 2.1-AA compliance for all web services provided by state and local governments. This is likely at least a year away from implementation and, if passed, would create a window of up to three years for local governments to comply.

HTML and Webpage Design

Specific to webpages, you should use HTML5 semantic styling instead of relying on text formatting to convey meaning. Semantic styling refers to styling based on what the block contains instead of how ti should be styled. For example, when HTML was new, you would make text bold by using the <bold> or <i> tags. In HTML 5, we use the <strong> tag for bold and the <em> for italics (emphasis) instead. These new tags do more than style the text, it coveys the meaning of the text. This allows devices which may be reading or formatting a site differently to convey both the way the text should be styled and the meaning of the style. This is useful for screen readers but also tools like Safari’s reader mode, which strips away unnecessary text and formatting to create a cleaner view for reading.

WebAIM has a WCAG checklist that it is a good idea to run through on webpages that you create or webapps that you are evaluating for purchase. They also have created the WAVE Browser Plugin which can be used in any web browser and will flag accessibility errors as an overlay on any webpage when the extension is clicked.

Microsoft Office and Google Docs

Both Microsoft Office and Google Docs include the ability to add alternative text to images. Also, while Microsoft and Google Docs both have the ability to use semantic styling to flag headers, captions, etc, most people change the text styling instead, creating an accessibility challenge. Semantic styling should be used wherever possible. Additionally, tables should be simple and avoid the use of merged cells. MS Office also has the ability to flag a row as a “header row” which improves accessibility.

Microsoft has a page with instructions for creating accessible documents and instructions on how to use the built-in accessibility checker for each app. Google Docs is far less accessible than Microsoft Office. Google Docs does have a page with best practices for accessibility, but the best bet for Google Docs is to use the free Grackle Docs plugin.

PDF Files

PDFs are notoriously difficult to make accessible. As a rule, any document scanned to a PDF is not accessible and there is no way to make it accessible except to transcribe the contents. Accessible documents exported through Microsoft Word or Grackle Docs are generally as accessible as a PDF can be. The use of PDF files on websites, especially scanned PDFs, is discouraged by the accessibility community.

Social Media

Social media posts commonly use images with text to convey meaning without supporting text. Social media posts should convey as much information as possible in text. Twitter also has support for image captions. Facebook has a full accessibility center, with information on how to caption images and upload video transcripts. You should also #camelCaseYourHashtags (capitalize the first letter of each word) to improve readability.

Robocalling Systems

Many schools employ robocalling systems such as Blackboard Connect that can call homes with weekly announcements or weather alerts. For people who can’t hear their phones or may have language barriers, this system can be incredibly complicated to use. Blackboard Connect, for example, supports TTY services that can provide a transcript of a call when requested. Putting transcripts of these calls on your school website or on social media is also recommended, or by SMS if available. Urgent alerts should go out across multiple media.

Teachers who need to call parents who may need text relay services for someone with a hearing or speech impairment can also 711 to be connected to an operator who can transcribe the conversation in real time. This service is provided by the FCC for free under Section 504.

Evaluating Content

When conducting a technical evaluation of content, the above should be used as a starting point to determine accessibility. Vendors should also include an accessibility statement on their website (see this example from Padlet) or should be required to provide one upon request as a part of a contracting deal.

While vendors may provide accessibility statements on their website, the VPAT (Voluntary Product Accessibility Template) is made available to vendors to describe to what extent they conform to WCAG or Section 508 rules, and any caveats related to their compliance. Many vendors will have this evaluation completed by a third party.

In unit 6, when we talk about procurement, it is recommended that contracts be written such that vendors should be required to implement and maintain WCAG2.1-AA compliance or be able to produce a VPAT and product roadmap to demonstrate a move towards compliance. See this sample VPAT and conformance statement from Canvas.

Supporting Tools

Many operating systems and applications have built tools to support accessibility. Beyond the designs mentioned here, computers have many tools to support access, including speech-to-text, high contrast modes, etc. Eye trackers and switches can also be used for people with limited mobility to interact with their computers. Apple has put together an accessibility website with information about their accessibility tools and tutorials linked. Microsoft has made accessibility a corporate focus, and have included tools and games designed first for assistive technology along with an adaptive Xbox controller, and features in Microsoft office that can highlight individual lines of text or break words apart by syllables and highlighting parts of speech. Chromebooks have more limited accessibility features, but are sufficient for most use cases. All three platforms, as well as Microsoft Office and Google Docs, now support voice-to-text functionality for students.
