So, this experience made me start thinking. I've done my fair share of web development. So, it's not like I was completely unfamiliar with accessibility issues. I know that images need to have alternate text, I know that it's good practice to put a "Skip to the Content" link at the top of the page to skip over navigational links, etc., etc. However, I didn't really begin to understand what it was all about until finally having an experience on the web were I was prevented from doing something I wanted to do because my senses were unable to decode the information being presented to me.
This was an entirely new experience for me, and it helped me begin to truly appreciate just how frustrating it is for people who have certain disabilities to try to use the internet.
Since I am in a course this semester about online / blended /distance learning, I naturally had several questions after this experience:
- How many people with disabilities take online courses?
- How many people with disabilities are not taking online courses because experience has shown that the course material is likely to be, at times, completely inaccessible to them?
- In terms of content format and delivery, what are the most likely accessibility offenses to be made against people with disabilities taking an online course?
- During online course design, what specific things should we be aware of to make our online courses accessible to everyone?
While searching around on the internet, I found a great little article that gave a nice summary of the legal issues (in the United States) and the technological issues surrounding accessibility in online courses. (Providing Access to Students With Disabilities in Online Distance Education: Legal and Technical Concerns for Higher Education, by Curtis D. Edmonds of Georgia Institute for Technology) While it didn't answer questions 1 and 2 above, it gave me some things to think about for questions 3 and 4.
Legal Issues
I don't want to spend too much time on the legal issues. There are some cases where, for example, institutions receive federal funding and must not, therefore, discriminate against anyone with disabilities. But for the most part, based on what I can gather from this article, it seems that the majority of accessibility law in the United States does not explicitly mention accessibility of online information.
However, it is not entirely unlikely for this to change in the future, and we as designers would do well to remember that it is always easier to design with accessibility in mind, rather than retrofitting old sites to bring them up to standards.
In any case, we should do this because it is right. That being said, let's talk briefly about the technological issues behind accessibility in online courses.
Technological Issues
Edmonds refers to two types of technological issues: "first generation" and "second generation" accessibility issues.
First-generation accessibility refers to our standard HTML pages being compliant with accessibility standards. This includes having alternate text for images, making judicious use of frames or other features that will cause problems for a screen reader, and so on. Typically, HTML accessibility issues are easy to overcome.
Second-generation accessibility refers to other, newer formats for media delivery--PowerPoint files, PDFs, Flash animations, etc. These types of technologies are harder to interface with screen readers and other assistive technologies, although attempts are being made to reconcile these differences. (See, for example, WebAIM.)
Edmonds also mentions that content management systems like Blackboard and WebCT present accessibility issues in and of themselves.
And lest I have implied here that only visually impaired persons are affected by these issues, keep in mind that people with aural impairment, photosensitive epilepsy, ADD/ADHD, and any number of other disabilities may have different experiences with your online content than what you expected.
On that final thought, go out and find some resources that will give you a better idea of what to keep in mind to make your online content accessible. Here are a couple to get you started:

Web Accessibility Initiative Guidelines and Techniques (W3C)
All great points about accessibility. I am in two minds in terms of distance education. I am not sure that we need to design all content to be able to meet all needs. It may be more effective to supply specific distance education to special needs students as they are also likely to have specific content needs. (Blind learners are probably not going to learning about visual design for example, and most deaf students are not likely to be doing any vocal performance). That was not meant to be be demeaning in any way, I am just suggesting that there will be audiences with a certain set of content desires and who will have specific needs, so it makes more sense to me to design to the audience rather than trying to make all things to all people.
