The main assignment for this week was to practice formatting a Word document to make it accessible.
Designing Accessible Text
A number of disabilities
can make it difficult for students to access standard hard-copy print
documents. When the student has an electronic text (e-text) document, many of
these issues can be remediated using assistive computer technology because pages
can be turned using a mouse, head-mouse, or even voice-activated technology;
text can be enlarged; colors can be changed; braille
can be created.
The key to using all of this technology is
e-text that has been designed with access in mind.
Designing
for Access
Page Layout
Text is easier to read and comprehend in smaller
blocks. Newspapers and magazines are printed with narrow columns because it is
easier for the human eye to scan a narrow column.
The amount of information that could be gleaned
from reading something on the computer was far less than could be understood
when reading the exact same information on paper.
There is limited evidence (see the work of
Michael Trimmer) that when engaged in similar tasks on the computer and on
paper, there is greater cognitive load associated with the computerized tasks.
Psychology has known since the '50s that
short-term memory only holds a small amount of information at a time. It is
easiest to process new information in manageable "chunks."
The necessity of presenting information in a
manageable way is amplified exponentially for students who have visual
processing issues—either low vision conditions or various learning
disabilities.
What all this means for page layout is that presentation
of the material influences how learners process information. Presenting
material in short, logical sections will allow the student to process the
material more easily.
You can use a number of tricks to make your
content more easily read and understood
"White
space" (empty areas without text or graphics, wide margins, short widely
spaced paragraphs) makes the content feel “smaller” and more manageable.
Frequent
headings break up and organize the text, as well as providing a sense of
accomplishment.
Bulleting
individual points helps to make content feel organized and easy to assimilate.
Creating an open, inviting document layout can make a huge difference in the ability of students who have visual or learning disabilities to access and learn the information.
Styles
Another aspect of document access is creating
one document that can easily be transformed into other document types. It is
possible, for instance, to create a document in MS Word that can be taken into
large print, braille, HTML, or PDF. The basis for the flexibility in
transformation is using styles during document creation.
A style is set of characteristics applied
to a paragraph (paragraph level styles) or character (attribute level styles).
The characteristics built into styles include
font style, point size, color, spacing, etc. All of these attributes have
implications for access, and we will consider each below.
Fonts
A font is the typeface (shape and style) of a
character.
Designers use different fonts to give different
feels to text. Fonts are important in document access because different fonts
have different readability.
There are two basic types of fonts: serif fonts
and sans serif fonts. Examples of serif fonts include Times New Roman,
Palatino, Garamond, and New Century Schoolbook.
Serif Font: Times New Roman
Sans (which means “without”) serif fonts do not
have these decorative elements. Sans serif fonts look very smooth. Examples of
sans serif fonts include Arial, Helvetica, Calibri, and Tahoma.
Sans Serif Font: Arial
In standard print materials (books, magazines,
newspapers, etc.), serif fonts are used as “body text,” the main reading text,
because they make reading faster and easier. Times New Roman, a classic serif
font, was originally designed for use in The Times newspaper.
Sans serif fonts are used in hard-copy materials
for headings, large type, and very small type.
The font style is important in a document
because it affects readability. Electronic documents are displayed on computer
screens or small portable devices. Those
same serif fonts that are so readable on paper suddenly become fuzzy blobs
onscreen. For individuals who have vision issues, this “fuzziness” can
present an added challenge. In recognition of this issue, American Printing
House for the Blind has designed a font (called APHont, pronounced Ay'-font) specifically designed for individuals
who have low vision.
Sans Serif Font: APHont
(See http://www.aph.org/products/aphont.html for a free download of APHont)
APHont has some unique features that increase
its readability for individuals with visual difficulties, including more even
spacing, letters that are wider and more open, and larger punctuation marks.

Font Size
The point size of a font is literally the
distance between the highest ascender and the lowest descender in a typeface.
Point size measures only height, not width.
Fonts are measured in
points, and in order to have a consistent measuring system, graphic designers
work in points and picas, rather than inches. So what is a point?
·
There are 72 points in
an inch.
·
There are 12 points in a
pica.
·
There are 6 picas in an
inch.
·
A standard 8.5 inch by
11 inch page is 51 picas by 66 picas.
·
The letter “p” stands
for picas and measurements are written as a number of picas followed by the
number of points. Half a pica (which is 6 points) would be written as 0p6.
Large
print is generally defined at somewhere around 14-18 point. It is not uncommon for students to request even
larger font. There is a limit, however, to how large it is reasonable to make
text on paper. It is generally not recommended creating hard copy large print
any larger than around 32 point. The student can use the computer to make the
text as large as she or he might want.
Color
There are a number of very important
considerations when it comes to color.
·
Contrast
·
Color blindness
·
Color processing issues
When you are creating a document, always be very
aware of contrast. It is generally best for readability not to overlay text on
top of a busy graphic. Similarly, it you are going to use a colored background,
make sure that the text contrasts strongly with the background. Never use light
text on a light background (for instance yellow text on white) or dark text on
a dark background (for instance black text on dark blue).
Also
remember that a significant portion of the population has some degree of
colorblindness (most often red/green). If
you are using green text for correct answers and red text for incorrect
answers, some of your students may be completely lost. It is fine to use color
as a reinforcement, as long as color is not the only indicator. You could, for
instance, have the word “correct” in green and “incorrect” in red.
It is quite common for students with vision
issues, including visual processing issues, to be affected in some way by
color. Students can alter the color as necessary of a fully accessible document
in the programs they use to access it.
Implications for Students
It is probably fairly clear why using a sans
serif font and larger point size will make text more readable for someone who
has low vision. What may be less clear is that similar adjustments can have a
profound effect on the readability of text for students who have learning
disabilities.
In our trainings, we teach instructors to
encourage their students with learning disabilities to experiment with the
following adjustments:
Use a sans serif font;
Increase the point size;
Increase the spacing between letters (expanding
the character spacing);
Increase the spacing between lines (called
leading); and
Play with different font and background colors.
For some students these changes make little
difference; however, many students find that such adjustments can have a huge
effect. Providing the student with an accessible document allows them to have
the empowering experience of taking control of their reading environment.
Using Styles
When a style is applied to a paragraph in MS
Word, other programs, such as the Duxbury Braille Translation (DBT) software,
HTML, and PDF, will recognize that style and create the appropriate format. In
addition, it is possible to create templates that use those same style names
and apply different font and paragraph attributes that are exactly what a
particular student needs. Styles are a very powerful tool in your accessibility
arsenal.
Certain basic styles work well in Word, DBT, HTML, and PDF. These styles include the following:
Certain basic styles work well in Word, DBT, HTML, and PDF. These styles include the following:
·
Normal, body text
·
Heading 1-3
·
List, list bullet, list number
·
Index 1-9
Creating an Accessible Document in MS Word
Documents created in MS Word are inherently
quite accessible, and there are some tricks that you can use to ensure that the
documents you create will not only be accessible in Word but also be accessible
when transformed into other formats (Web pages, PDF documents, braille
documents).
The basic tips to keep in mind include the following:
The basic tips to keep in mind include the following:
·
Use styles
·
Use tabs, not spaces to move words
·
Use the column format, not tabs to create a
columnar effect
·
Do not add additional spaces around punctuation
Selecting Text
Text can be selected in quite a few ways other
than swiping with the mouse.
·
Double click on
individual words to select them.
·
Triple click on a
paragraph to select it.
·
Use the right- or
left-arrow keys while holding the shift key to select individual characters.
·
Use the up- or
down-arrow keys while holding the shift key to select lines.
·
Hold the shift key and
tap home or end to select a line from the cursor point to the beginning (home)
or to the end (end).
·
Use shift page up or
page down to select from the cursor point up or down a page.
·
Use the “shift-click”
technique to select text between two points.
·
To select all the text
in the document, use Ctrl + A.
Applying Styles in Word
To apply a paragraph style, you simply need to
have the flashing cursor (the I-beam) in the paragraph that you want to format
and choose the appropriate style. You do not need to select the entire
paragraph, and in fact, it is better not to do so. Simply click the mouse once
in the paragraph you want to format.
Keyboard Shortcuts
If you are creating a lot of documents in Word,
you can save a great deal of time and energy by learning to use keyboard
shortcuts. The following styles have built-in keyboard shortcuts:
Heading One = Ctrl + Alt + 1
Heading Two = Ctrl + Alt + 2
Heading Three = Ctrl + Alt + 3
Remove manual formatting = Ctrl + Spacebar
Normal style = Ctrl + Shift + N
Change case = Shift + F3
Columns
If you need to use columns, it is crucial that you
work with either tables or the column setting. Do not use tabs or spaces to get columns. Columns look better if the text is justified.
Adding Alt Tags
My note: For Office 2013 Products see https://www.microsoft.com/enable/products/office2013/#create
Instant Large Print
Now that you have an accessible Word document,
there is one more trick to learn. It is very easy to change the font size in
Word. Simply select all the text in the document (Ctrl + A) and then use Ctrl +
Shift + > to enlarge the text. Continue holding down the control and shift
keys as you tap the right angle bracket (>) and the text in your document
will enlarge proportionally. To make the text smaller, use the left angle
bracket: Ctrl + Shift + <.
Accessible PDF
If you have used styles and included text descriptions
in your Word document, those features will transfer into your PDF document.
For more information on creating accessible PDF
documents and using PDF documents for alternate media, see the HTCTU training
manuals and tutorials:
Accessible HTML
Unfortunately there is no longer an easy way to
directly copy and paste your carefully formatted Word.doc into an WYSIWYG HTML
editor (unless you use a higher end HTML editor such as Dreamweaver) without
creating messy code.
Long method:
1.
copy and paste your
Word.doc into the TEXT MODE (or code) section of the the HTML editor.
2.
switch to the design or
WYSIWYG side and you'll see just your content as simple text.
3.
add styles back into
your content.
4.
If you now check the
code for your re-styled text, you'll see it much cleaner.

pages, see the HTCTU training manuals and tutorials: http://www.htctu.net/trainings/manuals/tutmain.htm
Accessible
PowerPoint
As long as you use the preloaded templates and styles in
PowerPoint, you will be creating accessible documents. Add alt text in the same
way as in Word.
If the PowerPoint document has been built on styles, it is even
possible to go very easily from PowerPoint to braille. From the PowerPoint
document, choose File and Save as Outline/RTF.
It is a simple matter to open the RTF document in MS Word and
change the PowerPoint styles from headings to index (i.e., change Heading 1 to
Index 1, Heading 2 to Index 2, etc.). The reformatted document can be saved as
a Word doc and transferred into Duxbury to create a braille document.
PowerPoint also works well for large print. Each slide can be
printed to a separate page, and the font size is usually very good for students
with low vision.
The larger issue with PowerPoint is making sure that the design
principles of layout and color are followed.
Not all the PowerPoint templates have good contrast. Choosing a
template with a dark even background color and a sans serif font in white or light yellow will ensure readability.
It is also wise to follow the “six pack”
rule. Include no more than six lines
on one PowerPoint slide.
Principles of Accessible and Universal Design
“Accessible Design” calls for design that
includes the needs of people whose physical, mental, or environmental
conditions limit their performance. “Universal Design” aims to extend standard
design principles to include people of all ages and abilities, but remains at
the level of generality, so it does not address all the specific needs of any
particular disability.
But even for people who do not have any specific
physical or mental characteristics that affect computer use, it has been found
that adopting universal design principles can reduce fatigue, increase speed,
decrease errors, and decrease learning time for all users. In many ways,
universal design addresses the larger issues of usability by making things
easier for everyone.
General Principles
Allow for flexibility
Provide choices in features and ways that tasks can be
accomplished
Accommodate right- and left-handed use
Allow the user to customize settings whenever possible
Keep in mind that people may be using adaptive technologies
Be simple and intuitive
Do not design something differently from user expectations just to
be different
Eliminate unnecessary complexity
Provide feedback
Minimize errors
Provide warnings
Build fail-safe features when possible
Do not establish patterns when you want people to pay attention
Include redundant modalities
Redundancy provides flexibility for different
user preferences, system configurations, or user abilities. This can be
accomplished by using more than one way to represent, display, and enter data,
such as:
·
using both a beep and a
menu bar flash to notify a user of an error
·
using text to label
images
·
redundantly allowing a
user to issue commands by typing or selecting something with a pointer
Avoid side effects
Side effects are actions that occur as the
result of user actions that do not seem to the user to be related to the
primary goal of the action. For instance, when starting a program that changes
system configurations (such as screen and sound settings) it should change them
back when the program is not being used.
Side effects should be avoided because they
cause particular problems for novice users and disabled users who may have
difficulty detecting or correcting certain types of side effects.
Web accessibility
The principles of design listed above apply to
both software and web design. Below are more web-specific tips.
Tips for building accessible websites
Labeling and markup
1.
Provide a text equivalent (ex: ALT text,
<LONGDESC>) for all non-text elements, especially those related to
navigation. Provide NULL values for unimportant graphics (such as divider
bars).
2.
Conform to current web standards: XHTML 1.0, HTML 4.01,
CSS 1.0.
3.
Use cascading style sheets (CSS) to control presentation
and layout rather than presentation elements and attributes, but organize
documents so they can be read without style sheets.
4.
Identify row and column headers for data tables.
5.
Use the <LONGDESC> tag to summarize graphs and
charts.
6.
Provide captions or transcripts and descriptions of
multimedia used.
7.
Provide alternate content for scripts, applets, and
plug-ins to compensate for the potential loss of information.
8.
Use the <LANG> attribute for screen readers that
support it.
Formatting
1.
Use relative units in CSS—em or % instead of cm, pt, or
px.
2.
Use ordered lists or number the lists on your web pages.
3.
When using tables, do not use structural markups for
visual formatting.
4.
Validate your work either using a validation and/or
correction tool.
Providing alternatives
Provide
ways to skip over navigation links and get to the main content of your web
pages.
Linking
1.
Create logical tab order
through links.
2.
Avoid hyperlinks longer
than 10 words.
3.
Use descriptive links
rather than “click here” to insure that links make sense out of context.
Hyperlinks
The ability to create and present "links" to other
documents and information is a major component of Web pages. While this is one
of the simplest methods to direct individuals to other Web pages, documents, or
to perform specific functions, hyperlinks can also have potential accessibility
challenges. The issue is not how hyperlinks function, but rather the
"name" that is used to identify the specific hyperlink itself.
One feature of screen readers is the ability to collect all the hyperlinks on a Web page and present this information to the individual. This allows the user to listen to a list of hyperlinks that are available on the page and navigate directly to the desired hyperlink as opposed to searching line-by-line.

This allows the user to listen to a list of hyperlinks that are available on the page and navigate directly to the desired hyperlink as opposed to searching line-by-line.
Links list in JAWS (screen reader)
When hyperlinks have a descriptive name that identifies the
purpose of the link, it is fairly easy for an individual to navigate the Web
page and choose the appropriate hyperlink. However, hyperlinks may be named in
such a way that either the purpose or destination of the link is unclear. For
example, often times a news headline or teaser to a full news article will have
the hyperlink text "Read More" for the rest of the article. An
individual using a screen reader will be informed that there is a hyperlink
called "Read More." On the Web page, we can visually infer that the "Read
More" hyperlink will provide more information about the news headline that
it is closest to. But for someone who is unable to see the page itself, the
text "Read More" does not provide the context as to the name of the
news headline. The problem is magnified when there are multiple "Read
More" hyperlinks on a page that takes the person to different Web pages. A
person using their voice to access the links on the webpage will be able to
navigate more efficiently if descriptive names are used for links.
Best Practices for Hyperlinks
Generally speaking, it is beneficial to identify the purpose or
function of the hyperlink as part of the hyperlink name. This often raises
questions as to "how much is enough" and "how long is too
long" regarding the name of the link itself. While there are no
established answers, the name should be descriptive enough so that the user can
understand or infer what information will be obtained by choosing that specific
link. Example: "Read More about the Carl Brown Scholarship" rather
than just "Read More."
For hyperlinks that take a user to different file types (e.g., QuickTime movie, PDF, Word document), it can be helpful to include the file type in the name of the hyperlink itself. This can be as simple as appending the file type to the end of the hyperlink name. For non-HTML based documents, you could also include the approximate file size. This is not specifically an accessibility issue, but allows the user to determine how large the file will be and whether or not the connection speed will support such a file size. Here are some examples of including the name and file information in a hyperlink: Adobe Acrobat Datasheet [PDF, 500K], Course Syllabus [PDF], Letter of Introduction [MS Word], View Memorial Service [Quicktime MOV]

4.
Clearly identify the
target of each link.
Displaying
1.
Provide enough contrast
between text and background color.
2.
Make sure that tables
make sense when read left to right, top to bottom, as this is how screen
readers work. Identify row and column headers, and use the <CAPTION>
and/or summary attribute and headers to describe the contents.
3.
Provide a
<NOFRAMES> option and use meaningful page titles if using frames.
4.
Use client side rather
than server side image maps and provide redundant text links.
5.
Avoid blinking,
flickering, or moving elements on your web pages.
6.
Provide closed captions
for all audio content that contains useful information or provide transcripts
for all audio content.
Tips for checking the accessibility of a website
1.
Turn off graphics
2.
Turn off sounds
3.
Check the contrast by
viewing the page in grayscale
4.
Turn off style sheets
5.
Turn off scripts,
applets, or other programmatic objects
6.
Use the largest font
size allowed by a browser
7.
Resize the browser
window
8.
Select all text and copy
it into a word processor to make sure it makes sense
9.
Use an automated
accessibility tool to check your website.

Web Accessibility and Usability Working Together
Web accessibility and usability are closely related; their goals,
approaches, and guidelines overlap significantly. It is most effective to
address them together in many situations, such as when developing websites.
There are a few cases when it's important to distinguish between accessibility
and usability, such as when looking at discrimination against people with
disabilities and when defining specific accessibility standards.
[Source: 3C http://www.w3.org/WAI/intro/usable]
Accessibility
The Web Accessibility Initiative (WAI) says that accessibility on
the Web "means that people with disabilities can use the
Web.” Read more about it at the Web Accessibility Initiative Web
site, www.w3.org/WAI/intro/accessibility.php.
Usability
Usability on the Web (or in other environments, documents, etc.)
means how easy it is to accomplish a given task, whether one is searching for
information, filling out forms, or just reading.
NOTE: It is
entirely possible that a document or a Web page can be accessible and yet still
be very cumbersome and sometimes nearly unusable. Documents and Web pages
should be created not only with accessibility in mind, but with both accessibility
and usability in synchronous harmony.

Usability and Accessibility - Everyone Learning
by David M. Peter
Define
accessibility
If we are to speak of accessible
web sites, it becomes evident that we do not mean access to technology. There
is an understood assumption that learners will have access to technology, even
though the quality and level of access can be somewhat varied. The assumption
herein is that each person or learner will have access to a computer.
One key element in determining
accessibility is discerning the perceptive abilities of the learner. While some
may identify elements as accessible, this degree of accessibility is, in part,
based on the perception of the learner (Winn, 1993).
While some would tend to limit the
definition of accessibility only to those constraints of the learner, there are
also accessibility issues that can be caused by technology (Salopek, 2001). And
the technological limitations are extremely important, and should be considered
within the scope of any web-based training. However, for the purposes of this
presentation, accessibility will be limited to learner disabilities.
Define
usability
While usability is more often
thought of as user-related interface design, it is indeed this and much more. Usability is, in essence, the ability of
the user to navigate through the site. It is the ability of a user, or in
this case a learner, to concentrate more on the content that is presented, than
on navigating through the site.
Nielsen's (1993) definition of
usability, although originated in computer software design, illustrates the
basic tenets that are included within web-based education: "Usability has
multiple components and is traditionally associated with these five usability
attributes: learnability, efficiency, memorability, errors, and
satisfaction" (p. 26). A much more simplistic definition of usability is
that "usability is not just a matter of whether or not it is possible
for a user to perform a task. It is also a matter of how easy and fast
it is for them to do so" (Nielsen, 2001).
In layman's terms, a usable
web-based educational unit leads the learner; it does not push the learner
through the experience. The elements of navigation are intuitive, and do not
require a considerable amount of thought to use them the way the designer
intended (Smulders, 2001). Many of the conventions that are associated with
usability are somewhat intuitive, if the designer/developer can think more of
the context in which the content will be presented.

Web Usability
Posted July 16th, 2007 by Mel Pedley
The dividing line between web accessibility and web usability is
often blurred and difficult to distinguish. Whilst there is no doubt that the
two topics do overlap to a significant degree, it is important to differentiate
between them. Unlike web accessibility
which impacts directly upon disabled users, web usability affects all users,
and can be defined as a measure of how easy it is for a generic site visitor to
carry out a task such as finding a given piece of information or buying a
certain product. However, there are accessibility benefits to be gained
from applying web usability principles to your designs. So let’s take a few
simply usability concepts, look at why they are important and see what effect
they may have on overall accessibility.
[Source: Web Usability http://accessites.org/site/2007/07/web-usability/]
A Comparative: Accessibility and Usability
[Source: A Comparative http://accessites.org/site/2007/09/a-comparative-accessibility-and-usability/]
Usability is a measure of how easy a system is to use.
Usability is made up of several key considerations:
·
Ease of learning—how
steep the learning curve to use a site is.
·
Efficiency of use—how
quickly a person can perform a task on a site, that may be finding a certain piece
of information, using the navigation, getting a download and many other tasks
(depending on what the site was created for).
·
Ease of memorization—how
simple (or difficult) it is to remember how to perform a particular task.
·
Error trapping—ensuring
errors are few in number and when they occur that the user experience is not
completely broken. While this is most relevant to dynamic data-driven sites,
small sites can often improve themselves with things like trapping of 404
errors or ensuring redirects are put in place when content is moved.
·
Satisfaction—a user is
able to perform a given task on a site satisfactorily.
WAVE
evaluation tool
WAVE is tool to help web developers make their web content more
accessible. WAVE cannot tell you if your web content is accessible. Only a
human can determine true accessibility. But, WAVE can help you
evaluate the accessibility of your web content.
WAVE is easy to use. Go to wave.webaim.org,
enter the web address of your page or browse to a file on your computer
(images, styles, and other media may not display for uploaded files) and select
WAVE this page!
[Source: WAVE Help http://wave.webaim.org/help]
What do all these icons mean?
WAVE will present your page with embedded icons and indicators.
Each icon, box, and piece of information added by WAVE presents some
information about the accessibility of your page. While WAVE
is most effective when used by someone knowledgeable about web accessibility,
people who are not web accessibility experts can also benefit from WAVE.
The report section at the top of the page indicates if WAVE
detected any errors or not. The absence of errors DOES
NOT mean your page is accessible. RED icons indicate
accessibility errors. GREEN icons indicate accessibility
features. The other icons and indicators indicate other elements that you
should look at. WAVE brings the underlying accessibility information of a page
to the fore-front so it can be easily evaluated in context.
You can view a brief overview of what each icon or indicator means
by clicking it and viewing its documentation or by accessing the documentation
panel.

Usability First - Accessibility
Usability and Accessibility – Breaking Down the Difference
Accessibility
Principles for Electronic Documents
Headings
Headings within a document (e.g., Web page, PDF, Word document,
etc.) can be used to separate content into "chunks" by identifying
the main ideas or concepts of the page. Similar to chapters in a book, headings
identify a change in the flow of information on the page and allow individuals
to visually scan the document for the desired information.
From an accessibility perspective, headings are valuable as they
provide individuals using screen-readers with a simple method to navigate
within the document. In a recent study investigating the browsing habits of
screen-readers users, over 75% of individuals claimed to use headings (when
available) always or often to navigate Web pages (http://webaim.org/projects/screenreadersurvey/#headings). Rather than navigating line-by-line through a document
or Web page, the use of headings allows individuals to move through the
information based on heading topic.
Newer Web browsers are also incorporating such functionality for
all users by incorporating key strokes that automatically scroll the Web page
to the next or previous heading on the page (as opposed to having to scroll up
and down to search for the next heading level). Headings also provide a
different method for individuals to "skip" navigational menus and
move the focus directly to the desired content.
Web designers can also use cascading style sheets (CSS) to
differentiate the presentational aspect of each heading on a Web page without
removing the meaning of the heading element to assistive computer technology.
The application of CSS to headings should not affect the ability of most
assistive computer technologies from interacting with the Web content.
More information about headings and semantic structure is
available at:
Images and Descriptions
An important component of developing accessible electronic
documents is to add a text description to images. This allows individuals who
are visually-impaired or blind using screen-reader software to "hear"
the description of the image. Additionally, for individuals who are using a
text-only Web browser or other mobile device, the text description still
provides access to the information when the images are not displayed.
Adding the alt-attribute is required under the WCAG 2.0, Level A
and the Section 508 Standards.
Assistive computer technology relies on the "alternate
text" attribute of an image to communicate the meaning/purpose of the
image. This alternative text in provided by the author. Depending on the type
of image you insert into your document, you will need to specify the type of
alternate text appropriate for the image.
When providing alternative text for images try the following:
·
Keep the alternative text brief, but be descriptive
·
If there is text content in the image, include that information in
the alternate text box
·
Do not use the word "image" to begin your description –
instead identify the type of image being used if it is relevant to the image
content (e.g., photograph, painting, screenshot, etc.)
·
If the image is very detailed and cannot be summarized in a few
sentences, consider placing additional information about the image into the
page text preceding or following the image

Naming Hyperlinks
The ability to create and present "links" to other
documents and information is a major component of Web pages. While this is one
of the simplest methods to direct individuals to other Web pages, documents, or
to perform specific functions, hyperlinks can also have potential accessibility
challenges. The issue is not how hyperlinks function, but rather the
"name" that is used to identify the specific hyperlink itself.
One feature of assistive technology is the ability to collect all
the hyperlinks on a Web page and present this information to the individual.
This allows the user to listen as to what hyperlinks are available on the page
and navigate directly to the desired hyperlink in question (as opposed to
searching line-by-line).
When hyperlinks have a descriptive name that identifies the
purpose of the link, it is fairly easy for an individual to navigate the Web
page and choose the appropriate hyperlink. However, hyperlinks may be named in
such a manner that either the purpose or destination of the link is unclear.
For example, often times a news headline or teaser to a full news article will
have the hyperlink text "Read More" for the rest of the Web page. An
individual using assistive technology will be informed that there is a
hyperlink called "Read More". On the Web page, we can visually infer
that the "Read More" hyperlink will provide more information about
the news headline, but for someone who is unable to see the page itself, the
text "Read More" does not provided context as to the name of the news
headline. The problem is magnified when there are multiple "Read
More" hyperlinks on a page that takes the person to different Web pages.
In the screenshot above, there are multiple "Read
More..." hyperlinks that do not provide any real information as to what
content the user may expect or to which specific news article the third
"Read More..." hyperlink will take them. Hyperlinks with more
descriptive names can improve the ability of a user to navigate and select the
desired information.
Best
Practices for Hyperlinks
Generally speaking, it is beneficial to identify the purpose or
function of the hyperlink as part of the hyperlink name. This often raises
questions as to "how much is enough" and "how long is too
long" regarding the name of the link itself. While there are no
established answers, the name should be descriptive enough such that the user
can understand (or infer) what information will be obtained by choosing that
specific link.
For hyperlinks that take a user to different file types (e.g.,
QuickTime movie, PDF, Word document, etc.), it can be helpful to include the
file type in the name of the hyperlink itself. This can be as simple as
appending the file type to the end of the hyperlink name. For non-HTML based
documents, you could also include the approximate file size. This is not
specifically an accessibility issue, but allows the user to determine how large
the file will be and whether or not the connection speed will support such a
file size. Here are some examples of including the name and file information in
a hyperlink:

Using Slide Templates for Layout
The simplest way to ensure accessibility of the information you
put into Power Point is to utilize the standard templates included with Power
Point. While you can drop content any place on the slide in a variety of ways,
only when you use the "Title" and "Content" areas can you
ensure the information will be presented to assistive technology.
Power Point provides templates with many different configurations,
allowing for many different types of content to be placed in your presentation.
To the left is an example of a standard empty template.
With this template, you could type in content, or click on the media objects in the center of the main content area to import that type of media. By using this template, you can ensure that your accessible information can be presented to students using assistive technology.
With this template, you could type in content, or click on the media objects in the center of the main content area to import that type of media. By using this template, you can ensure that your accessible information can be presented to students using assistive technology.
It is highly recommended to avoid the use of Text Boxes (from
"Insert" on the menu bar). Any content placed in these boxes may be
lost to assistive technology. In the best case scenario, content within Text
Boxes will simply be added to the bottom of the presentation when converted to
a Web page and may not be interpreted in the intended logical reading order of
the page. If you must use text boxes, please note that while the content may be
converted to the Web-based version of the presentation, the text box will
simply be added to the bottom of the converted Web page and not recognized as
part of the overall slide reading order.
Alt Text for Images
Microsoft PowerPoint allows document authors to include text
descriptions for images, on both Mac OS and Windows OS. This method should be
used for image content that is relatively simple and does not require extensive
description of the image. If a longer description of the image is necessary to
fully explain its content, consider inserting a more detailed description of
the image within the document text that precedes and follows the image.
When adding images in PowerPoint, it is important to provide a
description of that image so that a student who is blind or visually-impaired
can be provided information about the image. Descriptions for images should be
brief, yet succinct, and convey the meaning of the image. This is similar to
adding the "text description" for an image on a Web page (aka.
alternative-text, or alt-attribute).
Images that contain animation (animated .gifs) will not retain
their animation in the final Web-based version of the presentation. If your
presentation requires the sequential demonstration of the animated image, you
may want to consider showing the animation over several slides.
Microsoft PowerPoint 2010 (Windows
OS) and PowerPoint 2011 with Service Pack 1 (Mac OS)
1.
Open the document in Microsoft PowerPoint.
2.
Select the image and perform a right-mouse button click.
3.
Choose the "Format picture..." option.
4.
Locate the "Alt Text" tab, and click on it.
5.
Type your description in the "Description" field.
6.
The Title field is optional.
Tables
Tables in PowerPoint are one way to organize information visually.
However, such organization should be for data and not simply for presentational
elements. Data tables can be inserted into MS PowerPoint using either the slide
layout tool or by selecting "Insert" on the menu bar and choosing
"Table". Both options will give you a data table that you may then
insert information. Tables should contain text content; if using images or
other elements within a data table, then the table may lose its structure when
converted to the Web-based format.
Charts
and Graphs
Charts and graphs are another way in which tabular data can be
organized to demonstrate relationships (or a lack thereof) between different
values. When inserting charts and graphs, it is necessary to use the chart
function in MS PowerPoint in order to retain the underlying tabular data. For
individuals who are unable to view the chart or graph of the information, the
tabular data can provide additional information.
If you are using Excel (or another spreadsheet application) and
copy/paste the chart/graph into PowerPoint, you will need to reenter the table
data during the export process. Because the copy and paste process does not
retain the tabular data from the spreadsheet, it will be necessary to use the
step-by-step process to add the correct information.
Quick and Accessible Slide Creation
Begin in the Outline View
You can create the majority of your presentation within the
Outline view of PowerPoint. Simply use the ENTER key to create a new slide
title, and the TAB key to add sub-topics, you can easily create the primary
points of your presentation. By using this technique you ensure that the main
points are in the placeholders for title and slide content, and will be
accessible to assistive technologies.
Quick Keyboard Commands
Here are the keyboard commands for navigating within the Outline
View:
Promote a paragraph:
SHIFT+TAB or ALT+SHIFT+RIGHT ARROW
Demote a paragraph: TAB or

ALT+SHIFT+A
Turn character formatting
on/off: SLASH (/) on the numeric keypad.
Meta Data
Go to the FILE menu and access the PROPERTIES for the document.
Filling in the metadata for the presentation will make the presentation easier
to index and process by different technologies, including search engines,
alternate media conversion systems, and assistive technologies.
Design Styles
Once you have the outline portion of your presentation completed,
select a design style template and apply it to your presentation. Make any
adjustments that may be necessary to ensure your content fits on each slide and
is clearly visible with good contrast and separation between elements.
Non-Text Content
Finally, add images, graphs, charts, and any other non-text
content that you need to include in the presentation. Make sure to add
appropriate descriptions to all of these elements, and to provide an accurate
description of any tabular content within the notes field for the slide
containing the table.
Tooltips for Hyperlinks
PowerPoint allows you to insert hyperlinks to other slides in the
presentation as well as to websites on the Internet. When inserting hyperlinks,
be sure to make the action of the link the clickable anchor, and avoid the use
of "click here" as the clickable hyperlink. By using descriptive text
for your hyperlinks, individuals using assistive technologies can make better
sense of your content and more effectively navigate through the content.
Also, when using hyperlinks in your presentation, it is
recommended to include tooltips for the links via the hyperlink creation dialog
(CTRL+K).
Distributing Accessible PowerPoint
Presentations
Power Point 2010 for Windows can do an automated check of your
document to find commonly missing elements. To perform the automated check, go
to the "File" Menu, and then select the "Info" option.
From the "Info" screen, select the "Check for
Issues" button to reveal the Accessibility Checker. The Accessibility
checker will help find commonly missing elements and issues, but it is not
sufficient to guarantee accessibility.
Maximizing the accessibility of your PowerPoint presentation as
described above can help users of assistive technologies better access your
materials, but it might be insufficient to provide equally effective access.
Sometimes it is better to convert your PowerPoint presentation to another
format for distributing over the web, such as PDF or HTML, or even digital
video.
Saving as PDF
Saving your PowerPoint presentation as a PDF is a good option when
there is no accompanying audio for the presentation slides. You can configure
the PDF to have a single slide per page, or multiple slides per page, and you
can then use the tools in Acrobat Pro to ensure that the images for each slide
have appropriate alternate text. For more information on creating accessible
PDF documents, please visit the HTCTU website: www.htctu.net.
Saving as HTML
Saving your PowerPoint presentations as HTML is a great way to
provide the same functionality as the PowerPoint SlideShow tool, allowing you
to link each slide to the next, and create an interactive experience that
mimics the sequencing of PowerPoint, minus the animated transitions and
effects.
While the latest versions of PowerPoint limit your ability to
create an HTML export directly, there are automated tools available to assist
you with the process of creating accessible HTML versions of your presentation,
such as LecShare Pro, which is a 3rd party program available at substantial
discounts for educators (more information at: http://lecshare.com/). With all
of these tools for converting to the HTML format, you will need to ensure that
the proper standards for web accessibility are followed for you content.
By converting to HTML you have the greatest potential to add
accessibility while maintaining an interactive and rich digital environment,
but there can be a tradeoff in terms of time and ease of creation.
Rich Text Format or Outline
Saving your presentation as an Outline or RTF document
(essentially the same thing) will create a trext document with the content
entered in the main placeholders for each slide. Assuming you created the
presentation by using the default placeholders, saving as RTF or Outline will
effectively provide a complete rendition of your presentation, minus the
non-text content and design style templates.
Digital Video
If you are including a narration of your presentation, the best
strategy is to create a digital movie of your presentation, using your recorded
voiceover as the narration for the movie. There are a variety of tools and
strategies that can be employed in converting a PowerPoint presentation to a
digital movie, but regardless of the tool you use, you need to ensure that the
converted media file has captioning support, utilizes headings, includes image
descriptions, and is keyboard accessible.

Adobe
Dreamweaver
Accessibility Preferences
Dreamweaver provides built-in accessibility features to help in
the creation of accessible content. By enabling the options for form objects,
frames, images and media, Dreamweaver will automatically prompt you for the
requisite accessibility information whenever you insert these types of content.
You can access the accessibililty options through the main program preferences option panel.
You can access the accessibililty options through the main program preferences option panel.
For Windows systems:
Go to Edit>Preferences>Accessibility.
Headings
Using Dreamweaver, it is possible to impose some structure to the
document in order to separate the heading information from the various
paragraphs. The specifics of how to control the structure within Dreamweaver
continues to change as the program evolves, but regardless of which version of
Dreamweaver you have, you should be able to use the following process to
control the structure of your textual information.
Text is the basic starting point for accessible Web content.
Adding style and structure to your text allows it to be even more useable and
accessible. By using the “Format” menu, you can apply the heading and other
styles necessary for accessibile content.
You can also add Cascading Style Sheets (CSS) to further enhance or alter the appearance and layout of your content.
By accessing the “Format” menu, you can apply any of the selected styles to the content you currently have selected in the editor.
You can also add Cascading Style Sheets (CSS) to further enhance or alter the appearance and layout of your content.
By accessing the “Format” menu, you can apply any of the selected styles to the content you currently have selected in the editor.
NOTE – it is highly recommended to keep the same formatting for
the same structure elements (i.e., all the Heading 1's look the same, etc.)
throughout your Web pages. This can be controlled using the Format menu or by
using Cascading Style Sheets if creating Web pages.
1.
Move the cursor to the text information you wish to identify as a
heading.
2.
Refer to the Properties pane and ensure that you are looking at
HTML properties (as opposed to CSS).
3.
With the HTML properties toggled on, you can find the
"Format" menu where the heading styles are located.
4.
Choose the appropriate heading option (e.g., Heading 1, Heading 2,
etc.) or select Paragraph to identify the text passage as a paragraph.
5.
The text formatting may change. The presentation of the text size,
color, and font style can be manipulated by selecting Text on the menu bar and
choosing the Color option. Alternatively, if you are using cascading style
sheets (CSS), then you can modify your CSS values to alter the visual
presentation of the headings.
Alt Text for Images in Dreamweaver
1.
Place your cursor at the appropriate location to insert an image
and choose Insert from the menu bar. Select the "Image" option.
2.
If the accessibility preferences have been enabled, a prompt will
appear to enter the appropriate text description for the image. Enter the
description and select the "OK" button. This will provide the
necessary accessibility information for assistive technology.
3.
If the image is of no consequence (aka. eye candy) and does not
contain information pertinent to the information, then you can use the
drop-down list to select the <empty> option.
Data Tables
Tables used for presentation purposes are generally referred to a
"layout tables" while tables used to organize information are
referred to as "data tables". In the past (and to a certain extent
today), layout tables were used to control the layout of the page to insure a
similar site presentation across different Web browsers. Assistive computer
technologies initially had difficulty with the use of layout tables for the
Web, however, this is not as much an issue in recent practice. Today, most
assistive computer technologies can interact with Web pages that have been
created using layout tables without additional work on behalf of the Web page
developer. For word processing or PDF documents, using layout tables for
presentational purposes is not recommended and should be avoided. Layout tables
for word processing and PDF documents can cause a number of accessibility
challenges and limit the ability of assistive computer technology to interact
with the document content.
Data tables are exactly what the name implies - a table that
contains data about some information sequenced in a specific format. For
example, if you have a list of days, a list of appointments on specific days,
and a list of specific times for those appointments on specific days, it would
make sense to develop a table to display that information. For the Web, data
tables require additional code and information in order to effectively
communicate the information to the Web page visitor using assistive computer
technology. By choosing the appropriate options in the Table window, Adobe Dreamweaver
can automatically include the appropriate code and simplify the process of
creating accessible data tables.
1.
Select Insert
from the menu bar and choose Table.
2.
Enter the number of rows and columns for your table. You can also
determine the Width of your table (it is recommended to use percentages instead
of pixels for specifying table width).
3.
Select the box with the type of heading information that is
appropriate for your data. You should choose a header type for either the row,
column, or both.
4.
If necessary, you can enter a brief description for screen reader
users in the Summary
field. This is not necessary unless the table is overly complicated or might
contain visually-oriented data that needs extra explanation to be understood in
a non-visual context.
5.
By choosing the
appropriate "Header" option, Adobe Dreamweaver will automatically
code the table with the necessary accessibility information. All that is left
is for the document author to add the actual data to the table in Adobe
Dreamweaver. If you need additional rows or columns, simply add the rows or
columns as necessary and the accessibility information will be included.
Adobe
Acrobat PDF Documents
Accessible PDF documents can be created using the Adobe Acrobat
software application in conjunction with Microsoft Office
2000/XP/2003/2007/2010 applications for the Windows platform. Adobe has also
provided support for the creation of accessible PDF documents using other
software applications (e.g., Adobe InDesign, Open Office, Adobe LiveCycle Designer,
etc.). Using the appropriate Adobe tools, PDF documents can be created that
support the interaction of assistive computer technologies used by students
with disabilities.
For users of the Mac OS, you will need to have MS Office 2011 with
the 1st service pack installed. Unfortunately there is not currently a surefire
way to automate the process of transforming your accessible Office document
into an accessible PDF- you will need to perform manual checks and be prepared
to work with the Acrobat Pro application to create an accessible PDF document.
Note - the PDF documents that will be created are often called
"tagged-PDFs". Tagged PDFs provide the most flexibility and usability
for assistive computer technology. PDF documents created using third-party tools
(e.g., CutePDF, PrimoPDF, etc.) are not tagged-PDFs and would need to be
evaluated using the methods described in the Fixing PDF Documents section.
Note - while it is possible to create PDF documents that are
accessible, primary consideration should be given to HTML-based versions when
creating accessible electronic documents. If HTML-based documents are not
appropriate, then an accessible version of the PDF document type may be
considered. For more information about the use (and abuse!) of PDF documents,
please read http://www.alistapart.com/articles/pdf_accessibility (page will open in a new browser window).
Creating accessible versions of PDF documents begins with integrating
accessibility into the document authoring workflow. Most of the steps necessary
to creating accessible PDF versions are identified in the Microsoft Word 2007
section. The steps in this section identify methods for adding accessibility
information into the PDF document after it has already been produced. It is
highly recommended to add the appropriate accessibility information into the
document during the authoring phase (e.g., when in Microsoft Word, etc.)
instead of retrofitting the PDF version.
Adding Tags to PDFs
Note - it is highly recommended that the first step in creating an
accessible PDF is to use the original word-processing version of the electronic
document (e.g., the Microsoft Word version). Manually repairing PDF documents
can be time consuming when compared to using the original version of the file.
If you are creating a PDF document using the steps specified in the section
"Creating Accessible PDF Documents", then you do not need to
perform the following procedures. The following is applicable
only if you are starting with an untagged PDF document, for example, from a Mac
OS based version of Word.
Manually Adding Tags to a PDF
Adding tags manually to a PDF document using Adobe Acrobat does
have some limitations. While Acrobat can automatically add tags to a PDF
document, there is no guarantee that the document content will be tagged in the
correct reading order. Documents that contain regions of high complexity, such
as visually-rich layouts, may not result in a tagged structure that follows the
logical reading order of the original document. Any graphics or charts in the
PDF document may not be processed correctly and may be rendered as
"Figures" or "Inline Shapes". It is necessary to identify
these items and add the appropriate alternative text descriptions.
One suggested workflow may be as follows:
1.
Add tags to the PDF, if they do not already exist
2.
Evaluate the reading order of the PDF document
3.
Use the TouchUp Reading Order tool to reclassify content, add
headings, and manipulate the overall reading order of the document.
The above workflow is just one suggestion. As you become more
familiar with the PDF documents you interact with on a regular basis, you may need
to alter this general workflow to better suit your production environment.
Adding Tags with Acrobat X (10)
Acrobat X allows you to add tags to an untagged document, such as
is created with Microsoft 2011 on the Mac OS. To enable the Tags panel, right click
(or <CONTROL> + click for Mac) on the left-side border of the Acrobat
program window. You should see something similar to the screenshot below:
To add tags to your PDF, there are a couple of
methods you can employ:
1. With the Tags Panel displayed, you can right
click the top-level icon in the tags panel (displayed above next to the
highlighted text "No Tags avaiable") and choose "Add Tags to
document".
or...
2. Access the Accessibility Tools from the
"View" menu (View\Tools\Accessibility) and select the option to
"Add tags to document".
Your PDF document will be assigned tags based on the program's
ability to assess your content. You will likely need to use the Touch Up
Reading Order Tool to modify some of the tag types, and enter alternate text
descriptions for images, as well as declaring headers for your columns/rows in
any tables you use.
Adding Tags with Acrobat 8.x and
9.x
Adobe Acrobat 8.x and 9.x allows users to create a tagged PDF
document from untagged PDF files. Adding tags to a PDF will allow you to add
the appropriate accessibility information to the document (i.e., headings,
image descriptions, etc.). After you have added tags to a PDF document, it may
be necessary to that the document reading is correct.
1.
Open the PDF document that does not contain the tagged structure.
2.
Select Advanced from the menu bar.
3.
Select Accessibility.
4.
Choose "Add Tags to Document".
5.
After the program finishes processing the document, use Save As
and save the file with a new name.
6.
Open the new PDF document to check the logical order of the tagged
file.
For very large PDF documents, it may be better to separate the
file into several smaller PDF files before running the "Add Tags to
Document" function.
Checking the Reading Order of your
PDF Document
Checking Reading Order
It is important to assess the reading order of a tagged PDF
document, especially if you are unsure if the "Add Tags to Document"
function performed correctly (generally, this is not an issue with simple,
single column documents with no tables, but should be checked for multi-column
layouts or documents with tables).
An effective method to assessing the logical reading order of the
tagged PDF is to save the PDF as a text file. This will present to you a file
similar to how assistive computer technologies will read the document. Check
the logical reading order of the text file as to where there may be errors in
order of the tags in the PDF document.
1.
Open the PDF file in Adobe Acrobat, and select File from the menu
bar.
2.
Choose "Save As..." and you will receive the Save As
window.
3.
In the drop-down box "Save as type:" choose the option
Text (Accessible). This will create a text file that can be opened in any text
editor or word processing application.
4.
Review the text file for errors in the logical reading order of
the text.
If you are using Adobe Acrobat 8 or later, then this same
functionality is also available by choosing File > Export > Text >
Text (Accessible) from the button toolbar.
Repairing or Changing the Reading
Order with Acrobat Pro X
If the reading order for your document is not as you intended, you
can use the TouchUp Reading Order tool to fix the situation.
You can open the TouchUp Reading Order tool from the Accessibility
Tools, available from the Tools submenu located under the View menu. Once you have
accessed the Accessibility Tools from the View menu, they should appear as a
shortcut toolbar under the "Tools" shortcut menu on the right hand
side of Acrobat X.
Once you have opened the TouchUp Reading Order tool, you will
notice your content becomes outlined and numbered. The numbering reflects the
reading order, or the sequence in which the information will be presented to
other technologies, including the assistive technologies used by students with
disabilities. To change the reading order, click on the "Show Order
Panel" button from the bottom of the TouchUp Reading Order tool (or you
can right-click on the left-hand side of the Acrobat Pro X program window).
Once you have the Order Panel displayed, you can drag and drop the
numbered content into the desired location within the list of content displayed
within the Order Panel.
PDF Headings
For PDF documents, it is possible to add heading information when
using Adobe Acrobat after the PDF has been produced. However, when possible, it
is recommended to add headings while authoring the content - that is, while
using Microsoft Word, Open Office, or another word processing application. If
it is not possible to use the original word-processing application to add the
headings, then heading structure may be added using Adobe Acrobat.
1.
Open the TouchUp Reading Order tool (Acrobat Pro X: Under the
"Accessibility Tools"; older versions of Acrobat: Advanced >
Accessibility > TouchUp Reading Order).
2.
Identify the region of text content that is to be a heading.
3.
Using the cross-hair pointer, draw a box around the text
information. Make sure that all the text information you wish to include is
encompassed by the blue highlight. In the example below, the text "Geology
2.3 - Volcanoes" has been outlined in blue.
Specify the heading level (e.g., Heading 1, Heading 2, etc.) using
the TouchUp Reading Order panel. Repeat the steps as necessary to identify the
headings throughout the rest of the PDF document. In the example provided, the
text "Geology 2.3 - Volcanoes" is the main topic of the document and
would be assigned as Heading 1. If there are more than three headings in the
document, then use the Heading 3 option in the Touch Up Reading Order panel for
the remaining headings.
Image Descriptions in PDF
If you can describe the images in your source document, they might
be able to automatically convert inot PDF-based images with descriptions.
However, if you need to add image descriptions to the images in your PDF
document, the following steps are for you.
In order to add descriptions to your PDF document, you need to
have a tagged document!
After adding tags to a PDF document, it may be necessary to add
text descriptions for relevant images. The "Add Tags to Document"
function will process the PDF and mark content as text, table, or a figure.
Once an image has been identified and properly tagged, it is possible to add
the text description. If a figure does not warrant a text description, then you
can mark the element as "Background".
1.
Make sure the document you are working with is a tagged-PDF. Turn
on the TouchUp Reading Order tool (Acrobat Pro X: Under the Accessibility
Tools; Older versions of Acrobatr Pro: Advanced > Accessibility > TouchUp
Reading Order)
2.
Identify the image/figure in question and perform a right-mouse
button click.
3.
Choose "Edit Alternative Text...". Enter the appropriate
text description for the image/figure you selected.
4.
Choose OK to return to the main document.

Keep in mind that there is no requirement to
design your exams this way, but I think you may find these examples interesting
as they illustrate a different perspective when reading your own exam.
Here is an example of the typical exam question.
6: An audience member is worried about an
upcoming exam and is unlikely to
remember much of what the speaker says. This is
a type of
a. external
noise b. internal noise
c. physical
noise d. educational noise
Notice the lack of a colon at the end of the
question and the lack of periods at the end of each answer. While this LOOKS
fantastic and is very typical of exam design, this is what it would sound like
to a student using a screen reader:
"SIX<pause>an audience member is
worried about an upcoming exam and is unlikely to remember much of what the
speaker says. This is a type ofAexternalnoiseBinternal noiseCphysical
noiseDedicational noise"
In other words, the screen reader will, quite literally,
read what is on the screen: without proper sentence structure and punctuation,
the screen reader will run everything together.
This is how I would modify the test to make it
more accessible to screen readers.
6: An audience member is worried about an
upcoming exam and is unlikely to
remember much of what the speaker says. This is
a type of:
a. external noise.
b. internal noise.
c. physical noise.
d. educational noise.
This next example shows how an alternate media
specialist from your DSPS department might alter an exam for a screen reader:
The original version of the question:
15: Our beliefs, values, and moral principles by
which we determine what is
right or wrong are our _____.
a. laws
b. ethics
c. truths
d. rules
The modified version:
15: Our beliefs, values, and moral principles by
which we determine what is
right or wrong are our BLANK.
a. laws.
b. ethics.
c. truths.
d. rules.
Notice that I again make sure every word has a
period at the end. I also replaced the underline used to visually represent a
blank spot and I replace it with the word BLANK.
I’m trying to help the exam sound the way it
would in your own head when you read the question. I’m also trying to remove
any visually clear items that might make no sense to the student. That is,
while we see an underline representing a fill in the blank, a student may hear
“UNDERLINEUNDERLINEUNDERLINE” or some other odd sound by their screen reader,
depending on what they are using.
