Quality Matters Web Accessibility Standard

Amy Kinsel, June 2, 2010

Quality Matters Standard 8: Accessibility

8.1 The course incorporates ADA standards and reflects
conformance with institutional policy regarding accessibility in
online and hybrid courses.


8.2 Course pages and course materials provide equivalent
alternatives to auditory and visual content.



8.3 Course pages have links that are self
-
describing and
meaningful.



8.4 The course
ensures
screen readability.




Q: What do we need to know to meet these standards?



Physical Impairments and Assistive Technologies

Three types of impairment

Assistive technologies

1. Visual Impairment

2. Hearing Impairment

3. Motor Impairment


Adaptive keyboard


Closed captioning


Ergonomic keyboard


Eye tracking


Head wand


Mouth stick


On
-
screen keyboard


Open captioning


Oversized trackball mouse


Screen magnifier


Screen reader


Single switch access


Voice Recognition Software


Word Recognition Software



When designing for web accessibility, keep the
following goals in mind:

1.
Recognize the challenges students with various disabilities experience with
online courses.

2.
Identify various assistive technologies used by students with disabilities and
the implications each have on the design of distance education.

3.
Describe the roles and responsibilities of students, instructors, and their
institution’s disabilities services office in using assistive technologies for
distance education.



4.
Use computer operating features or tools to modify settings.


Visual Impairments

Q: What does a visually impaired person “see” in your classroom? How can your
classroom design enable use of assistive technologies such as screen readers?


A: Example of online content that is not “readable”:
http://www.youtube.com/watch?v=pMcfrLYDm2U



Solutions:

1.
Text equivalents for non
-
text items shall be provided. e.g., via "ALT
-

Tag. "

2.
Text shall use non
-
serif font such as Ariel.

3.
Text shall include headings, labels, tags, and tables of content.

4.
Text shall include meaningful names and titles for hyperlinks.

Captioning and Alt
-
text

Navajo student Tom
Torlino

in1882,
before attending Carlisle Indian School, in
Pennsylvania, and three months later.

Hearing Impairments

Q: What does a hearing impaired person “hear” in your classroom? How
does your classroom design enable use of assistive technologies such as
closed captioning? Do you provide transcripts of audio components?


A: Example of online content that is not “audible”:
http://www.youtube.com/watch?v=8q67ZrEZMqQ



Solutions:

1.
Provide text equivalence of audio materials.

2.
Use
Abobe

Sound Booth to convert audio files to text or to convert the
audio portion of a video file to text (
http://www.adobe.com
).

3.
Use
MAGpie

(Media Access Generator) to add captions to multimedia
presentations (

-
guidelines/magpie
).

4.
For an image or animation, type a description using Microsoft Word.



Motor Impairments

Q: How can a motor impaired student navigate through your course? Is it
possible to navigate without using a mouse or keyboard? Can a student in your
class complete assessments without using a mouse?


A: Example of online content that does not facilitate mouse
-
less interaction:

Solutions:

1.
Form elements (text field, checkbox, dropdown list, etc.) should have a label
associated with the correct form element using the <label> tag.

2.
Attach labels to standard form buttons so that the user can click on the label
itself rather than selecting small checkboxes.

3.
When using an image button rather than a standard button, the input should
have appropriate alt text.

4.
Icons used as links should also have HTML tags or an accompanying link.
