More than 54 million U.S. residents, or about 19 percent of the population, have some sort of disability, the U.S. Census Bureau reported.

<p>WCAG 2.0 explains how to make content:</p> <ul> <li>Perceivable (for instance by addressing text alternatives for images, captions for audio, adaptability of presentation, and color contrast); </li> <li>Operable (by addressing keyboard access, color contrast, timing of input, seizure avoidance, and navigability); </li> <li>Understandable (by addressing readability, predictability, and input assistance); and </li> <li>Robust (for instance by addressing compatibility with assistive technologies).</li></ul>

How will your students communicate when they leave school? How will they gather information? How will they say what they need to say?

The thing about toolbelts though, is that no two people ever really need the same one.

So the trick to tool use is to learn to evaluate tasks and environments and your skills and the tools themselves as they change and determine what works best for you. I call this the "TEST" - <span style="font-weight: bold;">T</span>ask - <span style="font-weight: bold;">E</span>nvironment - <span style="font-weight: bold;">S</span>kills - <span style="font-weight: bold;">T</span>ools, a specifically ordered reframing of <a href="http://sweb.uky.edu/%7Ejszaba0/JoyZabala.html">Joy Zabala</a>'s "<a href="http://www.ode.state.or.us/initiatives/elearning/nasdse/settintrogeneric2005.pdf">SETT</a>" protocol. A specifically ordered reframing designed for self-determination.

And on top of this, the tools most schools are devoted to are antiques which serve few functions anywhere outside of school. It is as if you were learning to build homes but were allowed to use only tools invented before 1940. You'd be close to unemployable when you finished that training.

The only way to allow students to assemble this essential toolbelt for information and communication is to to throw open your classroom and let the world in. How will your students know which calendar works for them - the one on their phone, Google Calendar with SMS appointment texting, Microsoft Outlook, or any of a dozen paper systems unless you allow them to try them out?

This is why - I think unconsciously - so many academics and educators resist contemporary ICT so fiercely. Accepting these new technologies means that the advantages they were taught to prize in themselves - their study habits, their ability to focus, their willingness to depend on authoritative sources and to observe classroom rules - might prove to be their undoing. And the disadvantages they despised in others, ADHD for example, processing information via pictures instead of the abstraction of text as another, the disadvantages that have been labelled as pathological "disabilities," might prove to be advantageous in this new world.

That ADHD kid might be far better in front of multiple monitors with a dozen windows open and 15 tabs going in Firefox than the professor and former high school valedictorian who is really uncomfortable if a TV is on while she is reading. That Asperger's kid who processes images efficiently might be far better at analysing changing maps than the text-dependent historian.

I feel the same watching most classrooms, seeing most reading assignments, observing how assessments are conducted in educational institutions. Yes, that carriage is wonderful, but the cars will rush past it. Yes, that calligraphy is beautiful but you just spent six months creating a single book. Certainly, that bronze sword is beautiful but the steel weapon will cut it in half. Yes, you did wonderfully on the multiple-choice exam but I need people who can find information and develop new ideas, not repeat what I already know. Yes, you read that whole book, but I need to know the range of observations from these twelve sources around the globe.

If you already lean toward the idea that accessible sites are good for humanity as well as for business, then this list will provide plenty of reference materials for you. If you don’t have a clue about the issues that surround Web site accessibility, then this list will help you to become well acquainted with the issues involved in this movement.

In my opinion, good semantic structure is one of the most essential and overlooked accessibility issues. A clearly-structured site is usually easier to understand, navigate, and is more accessible to users, particularly those with cognitive disabilities.
