Accessibility Standards Efforts
• IMS Guidelines for Developing
Accessible Learning Applications
• IMS Access For All Specifications
• New! ISO JTC1 SC36 Standard in
progress (IMS/DC/LOM)

Each Learner Learns Differently
• Varies even for the same learner: with
context and discipline
• The major value added by on-line
learning is the ability to personalize
learning
• On-line learning gives us the ability to
scale the individualized learning
experience to a large group of learners
Disability in Learning Context
• Disability= Mismatch between learner
needs and education offered
• Not a personal trait but an artifact of
relationship between the learner and the
learning environment or education
delivery
• Accessibility= The ability of the learning
environment to adjust to the needs of all
learners
• Environment includes AT tools
Two Approaches to Meeting
Accessibility Commitments
• One compliant resource for everyone
–
–
–
–
Rejection of valuable resources that are not compliant
Time and expertise required of all resource creators
“Accessible for everyone but optimal for no-one”
Two resource versions and maintenance neglect (diversity of
people with disabilities)
• A transformable, flexible resource system
–
–
–
–
Cumulative authoring
Matching resources
Resource re-aggregation
Providing tools needed by each learner
Accessibility =
• Flexibility of education environment,
curriculum and delivery
• Availability of adequate alternative-butequivalent content and activities
• Access to AT
Serving…
•
•
•
•
•
Learners with disabilities
Learners with diverse learning approaches
Learners with diverse hardware and software
Learners in disabling environments
Learners with diverse cultural or linguistic
requirements
• Anyone who diverges from the hypothetical norm
• Any context, including commerce, government,
publishing
Must avoid…
• Stereotypes and assumptions of
requirements
• Labeling or classifying users/learners in
politically sensitive ways
• Collecting irrelevant private information
Take advantage of ability to:
• Transform user interface of resource
(display and control)
• Re-aggregate learning resources
• Configure tools to meet user needs
Advances Response to
Equal Access Requirements
• Addresses legislative and regulatory
requirements
• Does not compromise the experience of the
student majority
• Does not unduly burden education provider
• Facilitates cumulative and collaborative
authoring
• Respects unique individual requirements
(learner-centric)
AccessForAll Standard
• A description of the learner’s or user’s
personal needs and preferences
(IMS AccLIP, ISO PNP)
• A description of a digital resource
(IMS AccMD, ISO DRD)
• Can be used with or without other personal
profiles and other resource metadata
Personal Needs and Preferences
IMS Accessibility for Learner Information
Package or AccLIP
ISO PNP
– How do I want/need things to be
displayed?
– How do I want/need things to be
controlled? (includes AT information)
– What content alternatives, equivalents or
helpful tools do I want/need?
– In what context?
Context
• When I’m tired
• When I’m using my portable
• When I’m at work...
Accessibility Metadata
IMS Access For All Metadata or AccMD
ISO Digital Resource Description or DRD
Information about
1. The Original Resource
• Can the display be transformed, is the method of
control flexible?
• Does it require hearing, sight, tactile sensation, or
text literacy?
• What are the locations of any known equivalents?
Accessibility Metadata
Information about:
2. The Alternative
• Pointer to the primary resource this is an equivalent
for
• A detailed description that parallels the content
requirements of AccLIP/PNP

Others
Web-4-All
• Developed for Industry Canada to ensure seniors, new
Canadians, and people with disabilities or literacy
challenges have computer access to services &
information on the Internet.
• Each user can select, save, and deploy their own interface
preferences using personal smart card technology that
automatically configures a suite of assistive software &
hardware.
• Makes public internet access locations accessible to those
requiring "non-standard" computer technology.
• Developed by University of Toronto & Canadian partners

E-learning environment that enables
learner-centric transformation of learning content
and delivery
• Authoring support for transformable content
and for metadata
• Browser
• Learning Object Repository
• Learner Preference System
http://inclusivelearning.ca
CWIS: ACCLIP/ACCMD in
Practice
• CWIS = “collection in a box” portal
software package developed for NSDL
by the Internet Scout Project
• CWIS is open source web software
implemented using PHP and MySQL
• CWIS is a turnkey package with a low
technology barrier to entry
ACCLIP with a Malleable User
Interface
• CWIS supports multiple user interfaces
and multiple user interface themes
• Interfaces are intended to be readily
customizable by the portal implementer
• Interfaces are “cascading” so portal
implementers only need to add or
change what is necessary to add a new
interface
ACCLIP and the CWIS UI
• Added “mini-wizard” to CWIS to solicit
AccLIP values from users
• CWIS UI is CSS-based
• AccLIP values (visual settings) are used
to customize user interface via dynamic
modification of CSS
ACCMD and Finding
Resources in CWIS
• Added AccMD fields to standard metadata
schema used to describe resources
• Results are flagged based on matching
AccMD metadata fields with AccLIP user
settings when browsing resources
• Results can be filtered based on AccLIP user
settings when searching resources
Looking at CWIS
• Software is free and downloadable at:
http://scout.wisc.edu/Projects/CWIS/
(live demo also online there)
• CWIS requires PHP 4 and MySQL and is
intended to run on a Linux or OS X web
server
• CWIS 1.4.0 includes mini-wizard and UI
modifications based on AccLIP settings,
AccMD fields and resource flagging/filtering
ANGEL Learning
• Commercial course management system
• Accessibility pilot in partnership with Penn
State University
• Adapting UI to AccLIP settings
• Importing a content package with AccMD
metadata and assigning appropriate
resources to learners
