So You Want To Build an Accessible eLearning Module?




A statement by the President's Council on Disability:

Technology for most people makes things easier. For people with disabilities, technology makes things possible.

Seeing People with Disabilities as a Culture

Some people may be offended by the idea of viewing people with disabilities as a culture. On first consideration, this seems to go against the idea of inclusion or equal participation by everyone. In the context of eLearning, however, and what we know about cultural differences in a learning environment, viewing people with disabilities as a culture may enable us to consider the differences in the way people engage, interact and learn in a digital environment. This shift in perspective during the development phase of a project can minimize, perhaps even close the gap that often times exists as a barrier to information access.

Recognizing Differences in the Way People Learn or Accept Information

Just as cultural differences bring diversity into the learning environment, so do the abilities and disabilities of the students and participants who will populate that environment. To build an accessible eLearning module, it is first necessary to understand the different ways people with disabilities learn or accept information. A broad understanding of the different types of functional disabilities and the assistive technology that people use to interact with computers is a natural place to start.

Types of Disabilities

Vision Impairment (Blind, Low Vision, or Color Blind)

• A blind person will not be able to see the computer monitor, the PowerPoint, or the video and may be using Braille output or a screen reader. A person with low vision may use ZoomText or the web browser to enlarge the text on the computer monitor. Make sure your presentation can accommodate these types of assistive technology. Also consider that during a webcast, visual information such as images, charts and graphs will not be seen by participants who are visually impaired. This does not have to be a problem if you include this type of important information in the audio portion of the training. If there is no audio component, include this information in the content of the training. In other words, do not use images alone to convey important information.
• Color blindness affects 8 to 10% of males of European origin. If important information is conveyed by color only, such as, “All form fields in red are required” some of the audience will not see it, and consequently, be left out. Do not use color alone to convey important information. Use words along with color to enhance usability for everyone.
• When using video, consider audio description to make sure that non-visual learners have access to all the information. One type of audio description is a synchronized audio file that accompanies a video or movie. In the quiet areas, a voice is describing the most important visual information such as who are the important players, place, time of day, dress, people (character information), action/movement/body-language, facial expressions, and tone of voice. Don’t be afraid to use color as a descriptor. Some visual impairments are acquired later in life, so color can be very meaningful. If synchronized audio description is not available or necessary, set the stage with a text description as an introduction to the video. This can be useful for everyone, not only people with vision impairments.

Hearing Impairment (Hard of Hearing, Deafness)

• Use captions with movies and video so people who are deaf and hard of hearing have access to all the information. Captions are useful for others as well. If anyone is not sure exactly what was said, the information can quickly be found in the captions. It is also useful to people who have English as a second language. Search engines can find files with captions as well. In fact, you can consider search engines as blind and deaf because they can only search for textual information.
Mobility Impairment (Physical Disability)
• Mobility impairment may be caused by traumatic Injuries, spinal cord injury, diseases or congenital conditions which cause loss or damage of limb(s).
• People with mobility impairments may use other ways to interact with the computer, such as: alternative keyboards, electronic pointing devices, sip-and-puff systems, wands and sticks, joysticks, trackballs, touch screens, and speech recognition programs. These are only a few examples. There are many kinds of assistive technology and many kinds of mobility impairments. New technologies are being developed every day to assist people with mobility impairments in using computers.


Cognitive impairment (functional cognitive disability)

• Cognitive impairment may involve:
1. Perception or understanding
2. Expression which includes speech, writing and appropriate behavior
3. Memory – short term and long term
4. Processing such as focusing and staying on task
• People with cognitive impairment may need additional time to complete a task. Additional time may be needed to read and comprehend the information, to respond or interact.
• Changes that occur automatically in a training module could be problematic. Offer the user a way to control the timing. By allowing the user to take the amount of time needed, focusing and staying on task will also be enhanced.
• Avoid moving or flickering objects as these can be distracting to people with cognitive impairment.


Other Considerations

What is the learning environment?

Is this a static online presentation in HTML?
Is this an interactive online presentation?
Is this a live webinar?
Is this a video or Flash presentation?
Summary: What software is being used and will it work with assistive technology?

How will you know if or when some of your audience has been locked out due to incompatible technology?

Is there a HELP section built into the eLearning module?
Have accessibility concerns been addressed in the Introduction?
Have you offered contact information to assist users in the worst case scenario?

What about registration and tracking for the class?


Who is responsible for registration?
If technology is being used for registration or tracking, are these processes accessible to users of assistive technology?

Things You Can Do to Address Accessibility Concerns

Provide written instructions.

• Consider offering a guide, user’s manual or HELP section to assist users when they encounter issues working with your presentation. The guide should include information such as:
1. The best browser for viewing your online presentation.
2. The software used to create the presentation.
3. Assistive technology that was used to test the presentation for accessibility.
4. Any accessibility considerations that were made when the presentation was built, such as adherence to WCAG Standards or compliance with Section 508 (see Do your Homework).
• Be sure contact information is included so that users who cannot work out their technical issues on their own may contact you to describe their experience and get a response on how to proceed. This not only shows that you want everyone to have equal access to the material, it will also assist you in troubleshooting the problem and finding a resolution.


Plan ahead and make appropriate accommodations.

• Know your audience and be willing to make appropriate accommodations. Consider the possible challenges or obstacles in plenty of time prior to a training event to offer accommodations to those who may need them. Accommodations may include sending a digital text version of the presentation and materials prior to the training. This will allow a person with a disability to become familiar with the material and prepare for the training. For a person with low vision, send a large print text version.
• An accommodation for someone who cannot hear may be a sign language interpreter to make a live webcast accessible. Real time captioning of a live webcast gives information access to a deaf user.
• If you are using a web application that offers user participation, be sure that screen reader users also have access. The application must be completely keyboard accessible and not require using a mouse. All of the text information must be available so that a screen reader can read it aloud.
• To accommodate users with cognitive disabilities, pages should be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz. Movement on the screen can be very distracting, not only to people with cognitive disabilities, such as traumatic brain injuries, or ADHD, but also to many other people in the general population and should be avoided if at all possible. Adhering to these frequency standards will also ensure that your presentations will not induce seizures.
• Use plain language at the appropriate grade level. This requires knowing your audience. If you are creating an eLearning module for college educated professionals, use language that is appropriate. If you are creating an eLearning module for the general public, consider writing at a lower comprehension level. This grade level discrepancy can make or break a successful training module.
• Keep it simple. Be consistent in layout and design, and especially in navigation. Use a template if possible. The more time the user can spend on the content, the easier it is to navigate within the module.


Do your Homework

To build a better eLearning application, learn more about the different ways people access information online. The following resources address many aspects of accessibility, including more information about specific disabilities, different types of assistive technology, disabilities etiquette and using appropriate language and terminology.

Summary


Culture, as a social practice, is not something that individuals possess. Rather, it is a social process in which individuals participate, in the context of changing historical conditions. As a "historical reservoir", culture is an important factor in shaping identity[1] Some critics of cultural identity argue that the preservation of cultural identity, being based upon difference, is a divisive force in society, and that cosmopolitanism gives individuals a greater sense of shared citizenship.[2]. That is not to always be divisive.



Wikipedia on Cultural Identity: http://en.wikipedia.org/wiki/Cultural_identity


Viewing people with disabilities as a culture can be a tool for the eLearning developer. An understanding of the technical challenges and limitations encountered today by people with disabilities and users of assistive technology can form a foundation for development of accessible eLearning modules. This can lead to a transition in the eLearning environment from one that historically locks out users of assistive technology, to a more user-friendly and accessible digital system for all users.

Efforts in the development of accessible electronic media are one step toward a more inclusive society, a society where universal design is the norm and where one’s abilities or disabilities or cultural differences do not limit one’s opportunities to participate.
