PEW – Teens and Social Media,
12/19/2007
 64%
of online teenagers ages 12 to 17 engage in
at least one type of content creation, up from
57% of online teens in 2004.
 35% of all teen girls blog, compared with 20% of
online boys, and 54% of wired girls post photos
online compared with 40% of online boys.
 Online teen boys are nearly twice as likely as
online girls (19% vs. 10%) to have posted a
video online somewhere where someone else
could see it.
Demographics of Internet Users
PEW - Information Searches

financial experts
 45% sought out friends and family
 36% consulted newspapers and magazines
 13% went to the public library
PEW –Teens and Technology,
April, 2008
 93%
of teens say they write for their own pleasure
 85% of teens ages 12-17 engage in some form of
electronic personal communication (email, chat)
 60% do not think of e-text as “writing”
 50% use informal writing styles instead of proper
capitalization and punctuation in their school
assignments
 38% have used text shortcuts in school work
(“LOL”)
 25% have used emoticons☺ in school work

Online Learning Statistics
 Almost
3.5 million students were taking at least
one online course during the fall 2006 term.
 The 9.7 percent growth rate for online
enrollments far exceeds the 1.5 percent growth
of the overall higher education student
population.
 Nearly 20% of all U.S. higher education students
were taking at least one online course in the fall
of 2006.

Simplify Classroom Interface
Provide
ample contact information
Provide simple navigation in the left panel
with limited choices
Change the standard button labels for
clarity
Use text buttons whenever possible
Use larger text in a simple font with good
contrast
Content in multiple formats
Online Class Accessibility Issues
All
items in a classroom are arguably
necessary for a student, so there is a
greater potential for lawsuits.
Instructors need to be an accessibility
champion.
Instructors must be aware that
accessibility does not ‘come’ with an
application they choose to use with class.
Profiles
Delete Unused Tools
Less choices means a more
easily understood interface.
Keep number of choices
below 7 if possible.
Delete Unused Navigation
Provide Simple Class Name
Heading
Contrast
Clear type
No Animation
Provide Alternative Text
For
persons with visual impairments,
alternate methods of accessing the value
and meaning of images is essential.
Golden rule: for any image or graphic
content displayed on your website, ensure
a text alternative and description is
available.
◦ Exception - decorative images or spacer gifs
need a null alt attribute, or alt=“”
Add Alternative Text to Pictures
Select image, right-click for menu, choose size option
Blackboard “Alt Text”
Dreamweaver “Alt”
Provide Documents in Two
Formats
Video
needs captions or a transcript
Podcasts need a transcript
PowerPoints need an outline provided in
plain text. Provide visual description
where necessary.
Provide documents for download as well
as presenting content in a Blackboard
classroom
PowerPoint Suggestions
Use text no smaller than 24 pts.
Use good contrast and an easy to read font.
Use images or graphics to provide clarity.
Copy and Provide Outline in
Plain Text
Click on
Outline Tab
Select text
Copy/Paste to
txt document
Upload to
Blackboard
class
Save Word Documents
to Filtered HTML
Best Practices for Text
 Place
all text in a single column. Multicolumned text is confusing to screen readers.
 AVOID USING ALL CAPITAL LETTERS.
 Use simple easy-to-read typefaces. San serif
fonts are easiest to read on the screen (ex:
Verdana, Tahoma, Arial).
 Do not use italics or fancy fonts.
 Use good contrast between background and
text color.
Use Headings Properly in Word
If you only change the font style, size, and
color, no extra emphasis or info is given by
the screen readers.
Accessibility Concerns
with Chat
Not everyone can use chat. If you decide
to use chat in your classroom, consider
recording the discussion and providing a
text file for an alternate assignment.
Web 2
Blogs, Wikis,Virtual Worlds, and Social and
Sharing Networks
Advantages to Web 2
Cost
in labor and system upkeep by third
parties.
Blogs and wikis can be continued past the
end of a semester.

world.
Application training for students is
minimal.
Disadvantages to Web 2
Privacy
Interference/spamming/griefing, or
other
abuse from non-educational individuals
No control over changing applications or
content if vendor goes out of business
Not accessible to some students

Facebook
is an effective and well
organized way to publicize, communicate
and share information with a group.
Students post pictures, send messages,
and post times and dates of events.
 This is an example of a club that was

Del.icio.us Benefits
Students
keep their resources after they
leave school, which makes it truly life long
learning and keeps the students in contact
for resources later.
It also helps students and instructors
share a wealth of resources with each
other.
Collaborate with professionals all over
the globe.

Twitter – sharing micro tasks
Twitter
Twitter
allows you to broadcast and
receive messages from your computer or
cell phone up to 140 characters in length.
 ‘Subscribers’ can either broadcast or see
a message, which is called a “tweet.”
The key factor with using Twitter is that it
takes the blogging concept to a whole
new level of portability via cell phones,
making it highly mobile.

What is a virtual world?
A
virtual world is a computer-based
simulated environment intended for its
users to inhabit and interact via avatars.
These avatars are usually depicted as
textual, two-dimensional, or threedimensional graphical representations,
although other forms are possible
(auditory and touch sensations for
example). Some, but not all, virtual worlds
allow for multiple users. - Wikipedia

Identity Issues
Can Second Life be ADA accessible?
 Concerning
the visual and 3-D environment of Second Life,
you may be interested in how it is currently used:
◦ Provides mobility for residents that have MS, Cerebral
Palsy, or other similar impairments. Many avatars created
by users with mobility impairments use wheelchairs in
SL.
◦ Text chat is not easily read by a screen reader. A screen
readable text-only version of Second Life exists for
residents without sight. Chat and voice logs can also be
recorded for anyone that has a technical or cognitive
impairment, or for later study.
◦ The SL interface and chat text size is customizable and
makes use of alt-keys.
◦ Through an avatar, residents with real life (RL) physical
deformities or obvious disabilities can become ablebodied, and vice versa.
◦ Autistic students can practice social skills.
Can Second Life be ADA accessible?
Disability
awareness simulations can be
structured using avatar wheelchairs, or by
changing chat and voice options.
Accessibility can be achieved in most
applications with work from the facilitator
hosting the event.
A real time streaming event would require
real time captioning or interpretation.
Visual description should be available for any
environment, as an explanation for odd
sounds or text/voice chat references.
SLeek
SLeek
is an open source low tech client
to use SL without all the fancy graphics. It
would be useful for individuals with visual
impairments, but consider also its use for
students in low tech environments, for
instance at home on an old computer
with a modem
http://code.google.com/p/sleek/
Movable Life
 MovableLife
allows Second Life users to log in
to Second Life using only a web browser.
MovableLife allows chat, IM, search, teleport,
manage friends, groups, and much more,
providing a Second Life experience without all
the 3D graphics. Movable Life article
 Another advantage to using a regular browser, is
that it can be used by iphones and other
devices, and also the bandwidth is reduced for
use on older computers with modems.

Accessing Second Life: Universal
Design in a Virtual World
Student Recruitment
Wilde Cunningham – SL avatar
 An
avatar controlled by nine adults (ages 30-70)
with cerebral palsy at a day care.
 Most are wheelchair users and rely on help for
almost all aspects of their daily lives, yet in
Second Life they have built their own houses,
have pets, gardens, even a baseball field. They
also have many close friends and a large social
network.
Wilde Cunningham – SL avatar
 “Second
Life gives me the chance to be the
person I feel I was born to be,” says John S, 32,
one of the group. “Being in Second Life is how I
imagine an innocent man who had been locked
up wrongly feels when he is finally set free. In
Second Life I get to call the shots.”

creation of a new nightclub in Second Life called Wheelies.
Wheelies aims to "make guests feel comfortable about
disability as well as dancing, drinking and just plain having a
good time.“

Takeaway
Even
though a specific online application
may not be accessible to a student, the
general framework of wikis, blogs, online
learning environments, and virtual worlds
is valid and with careful choices, most can
be used with a few refinements.
Go
