Here is an outline of my research for a course on Notable Women last session at Osher Lifelong Learning Institute at Yavapai College. I was fascinated by the question: what happened to the rest of her life after the incidents portrayed in the “Miracle Worker” plays and movies. As my reading progressed to reveal her decades of activist publication and public attention, the deeper question became “how did she cognitively process so many other writings and human contacts into coherent and relevant materials that sustained her spirit and finances?”.
speaking personally, as I’ve portrayed earlier in this blog, I have rewired my brain to read and write differently without using vision. Now, the Internet and trusty screen readers and RSS clients bring me loads of information, but I still find it difficult to organize even a small article like this post. Keller published many articles in popular publications like “Ladies Home Journal” but she also emoted some very fine rants on socialism, unions, suffrage, and disability civil rights.
Answering my questions from the resources below, especially the New Yorker article, she: mastered French and German at Radcliffe; read European newspapers; always had personal assistants; selected topics of interest for her human readers to communicate by hand tapping, lip reading, or Braille translation; wrote sections on a Braille typewriter, assembled and edited with assistance; wrote and received copious letters in the style of the time; made friends with Mark Twain, Alexander Graham Bell, and the presidents du jour; traveled extensively; and generally got around a lot. Whew! But still, how does one assemble a model of the world coming without hearing or seeing? The New Yorker article portrays her cognitive functioning as much like poetry or highly flowery narrative. That is, she took in facts and physical object descriptions, asked questions, built a sense of her surroundings, and embellished with imagination constrained by her editorial assistants. Yet, there is such a difference experiencing the situation of labor unions from a film like “Norma Rae” and reading about sweat shops and factory safety mishaps. It still intrigues me that her reality matched sufficiently her colleagues and acquaintances that she could not only participate but also influence her times. Interestingly, some of that interaction came from a silent movie, vaudeville infomercial’s, and an attraction for press attention that vies with modern athletes and actors.
Yet, that same cognitive generative process caused lifelong doubts in others about her actual abilities versus the influences of Teacher and other assistants. A bizarre accusation of plagiarism arose at age 12 when professional pride and pettiness ran amok over a misunderstanding of originality of a story she told in a letter. Now, today we cannot get college students to differentiate copy-paste research from critical thinking, so one wonders how a 12-year-old could really appreciate the social significance of separating what one is told, holds in memory, and retrieves as a story gift from copyright and issues of attribution.
Well, anyway, if you wonder how minds work with different sensory limitations, take a look at the documentary on Youtube, the New Yorker analysis, and some of the cited oddball life passages.

Finally, I think HK would have been great on Twitter, with pithy, passionate expressions of her daily insights, frustrations, and relationships. Happy 5th birthday, Twitter and many thanks to Accessible Twitter for keeping me in touch with the world.
I’m a legally blind retired computer scientist. As I gained proficiency with assistive technology for reading, writing, and communicating, I faced similar costs, barriers, grievances, and coping challenges as thousands of other computer adept late career people. However, I also take a keen interest in effectiveness and usability of my access tools and the media they work upon as a total system for processing information in our marvelously plastic brains. And, as former educator, researcher, and manager, I look upon my profession as contributors to both sides of the problem and solution arenas acting under broader social forces from government, demographics, and mainstream technology industries.
May I share my unique experience with you? Here’s my take on the current state of computer science (CompSci) related to Persons with disabilities (PwD)in general and the specific opportunities for visually impaired persons. Assistive technology refers to software like screen readers that use text to speech and keyboard focus interactions with operating systems, applications, and web pages. Accessibility is a matter of degree to which the applications, OS, and web sites support assistive technology. to achieve the same performance and satisfaction as all other users.
responsibilities, accountability, openness, and Opportunities for CompSci
are educational institutions now, in 2011, ready to embrace disability civil rights? Is the academic computing field prepared to integrate advances from the separated assistive technology industry and the generation of students raised with strong but different skill sets? Can CompSci meet its aspirations of providing the 4th R of education for everybody? Will there be movement to re-mediate decades of deficient designs of web information management systems and individual documents? where does CompSci and information technology fit into this solution, or problem, space?
basic accountability as an academic discipline
Like all educational fields that use web resources to assist education, the CompSci and IT fields are clearly responsible for adhering to standards that mitigate barriers for people with disabilities using available assistive technology. Especially where costs of access technology and special skills have been attained through rehabilitation resources or even individual investments, this is immediately a matter of jobs for PwD. Moreover, there are ripple effects for all intermittently or eventually disabled persons or caretakers, or tax payers, and that is everybody several times over.
Have our fields done well so far? No, as shown by flaws revealed traversing the 2010 Computer Science Education week and partner websites (see data below). These are rife with stumbling blocks, and generally exhibiting indifference to established design and usability practices. Barriers are unnecessarily erected, and unfortunate messages of ignorance and indifference indicate a field not so much up with trends in user oriented communication. or even acknowledging sensory differences in users.
domain responsibility of the CompSci field
CompSci and IT bear the additional responsibility of producing the tools, languages, and patterns; the programmers, designers, and testers; the processes, quality assessments, and design strategies; interfaces, interaction models, and transactions; the books, published articles, and motivations; and so on, that underlay the capabilities for educational institutions to meet their basic accountability.
Further CompSci responsibilities are the development of cultures where people with disabilities exhibit their skills and tools to demonstrate how well they can produce software and hardware products and artifacts. Beyond Cultural integration is the need for domain knowledge, e.g. how screen readers and caption systems work and how artifacts must be designed for smooth operation by persons using assistive technology.
CompSci has often promoted pedagogical tools like Alice and scratch that explicitly bar people with certain disabilities getting equal footholds in and excitement about computing. Nevertheless, many people have not only become high functioning but also innovative regarding access technology, including the very products I’m using to write this article. A community of computing oriented professionals have banded together to produce the aforementioned standards, tools, processes, and businesses that await adoption by CompSci and IT.
Computational thinking opportunities await CompSci
In fact, the above strengths and weaknesses of the social motivation for overcoming limits for PwD are truly, really, beautifully illustrative of computational thinking. The widely used WCAG standards are a fledgling “science of accessibility” with tested hypotheses, guidelines,, terminology, and a blogging trail of intellectual progress. Good web pages are all about semantics: markup, logical structure, sound relationships (in a database sense), and progressive enhancement design to transform semantics with syntactic elements like color and graphics. The essence of accessibility is support for multiple representations where access tech supplements or replaces sensory limits. Abstraction, semantics, representations, implementations, relationships, … are the sound principles for achieving the technical aspects of basic accountability and additional responsibilities of computing fields.
Hey, take the challenge! What should CompSci and IT do?
- clean up our websites, a good goal for Cs education week 2011. Read the standards, use guidelines and tools to re-mediate and assess quality, then do the work. With remediation of technical zits will come a better understanding of the computational thinking issues that should lead to improved designs.
- Take responsibility for explaining disabilities and accessibility to educational colleagues. Incorporate local disability service professionals and
enlist the fear and concerns of university management to assure resources.
- audit all pedagogical tools and artifacts and label each for sensory and disability limitations. Then progress toward the better products available while applying computational thinking for more universal representations.
- Use the competitive, exciting advances of tablets, smart phones, text to speech, and accessible apps to motivate and explain both how accessibility works and why it matters in our economy. Just open up the hood under the accessibility options and check out the high performing speech interfaces.
- Learn to talk with persons with disabilities about their
needs, high functioning skills, innovative tools, and culture.
- Do not feel bad about lack of experience or past mistakes. We are all overdue with a dose of karma, such as this writer who cannot use or maintain security education applets I developed five years ago. Ouch!
Overall, let’s open up a new field of computing, pull publications out of the ACM pay wall, and lead the way through computational thinking.
Issues, evidence, and epiphanies
are the feds really coming after universities for inaccessibility?
The Obama administration departments of Justice and department of education Office of civil rights have certainly shown signs of action backed up by White House ceremonies and initiatives:
- The amazon Kindle lit the fires in 2008 with a proposed field study in classrooms. Not so fast, charged the National federation of the Blind through an Arizona State journalism student and accessibility activist. Blind folks cannot use the Kindle so the field study could harm students and end up invalid for the college population including PwD. This led to a warning”>”dear college President” letter from DoJ of intention to pursue grievances when emerging technology is considered or adopted while substandard for visually impaired students. By the way, amazon flubbed its redo of the Kindle by making books sometimes readable but not the menus and buttons for actually operating the device. See our our post :Amazon Kindle, Arizona State, What a mess!.
- Penn state fell into the bad vibes of NFB through complaints of students and faculty about websites, course management systems, classroom display systems, and campus banking devices. Such deficiencies are shared at other universities as expressed by the chronicle of Higher education article demanding access featuring the activist journalism student at ASU involved in the NFB Kindle trial fracas. Similar views are often expressed in the professorial Planet of the blind blog.
In the broader social context, the USACCESS Board is holding hearings which suggest insistence upon using W3c WCAG standards.
- Also see the excellent 2010 disability update day in Washington Top 2010 disability events podcast.
On the positive side, California state University system is often praised for its improvements. Sadly, a funded study of analysis of university web accessibility is hidden in an obscure journal.
If all this comes to fruition right under the noses of congress, regulatory and advocacy will open many doors for computing professionals with a bent toward social entrepreneurship and intriguing technology advances. By the way, the professional accessibility virtual water cooler spreads daily updates on Twitter .
What will happen if universities are forcefully or voluntarily driven into accessibility? We may know by 2012.
why hasn’t accessibility and assistive technology taken hold in computing research and education, ?
As a former educator, I’ll take the all purpose route of blaming the textbooks? One form of blame is the presentation of content as in printed tomes, derived from WORD documents, spruced up by publishers, and embellished with instructor power points all performed without consideration for readability by print disabled students. This forces, I’m not kidding, hundreds of pages to be scanned into electronic forms where most original MS-WORD structure is lost, i.e. hours of labor in an error prone incomplete reverse engineering process.
How dumb is that?well, nationally, this problem is being rectified by bookshare under a department of education contract to adapt, just once in an industrialized manner, many college and K-12 textbooks. However, there isn’t a similar well known cooperative effort specializing in computing texts, or efforts by publishers except for Oreilly Media contributions of its electronic versions directly to bookshare.
Now, consider textbook content itself. Are there any, like more than 0, standard computing texts that contain chapters and exercises on assistive technology and accessibility as recommended in standards and produced by specialized branches of software and publishing industries? Please comment any examples.
the root of all evil in textbooks goes back to curricula accreditation. Omitted there, and frozen into practice, accessibility principles are instead forced into industry workshops, such as Knowbility Access U and Open Web Education Alliance. This further differentiates career paths with web development considered a craft, combining touchy feebly communication, advertising fodder, turnkey content management systems, and a steady flow of freelance or in house jobs open to lesser educated mortals.
The irony is that web accessibility is one of the best exemplars of “computational thinking” that has driven some higher echelons of CompSci leaders. See my 2009 post on many ways accessibility and assistive tech put computational thinking in action for pedagogical practices.
really? is the W3C nurturing a “science of accessibility”?
Read the W3C Web Content Accessibility Guide 2.0 and “Universal Design for Web Applications” by Wendy Chisholm and Matt May for lively explanations and motivation for the WCAG standards.
There’s an amazing amount of thought hammered into shape and utility in these guidelines and scenarios on the w3C web site. Rather than tons of funded research projects to identify hypotheses and perform experiments and build prototypes, the standards bodies combine experiences from developers, authors, consultants, and gadflies who really care about their subject. social and technical consequences. Fights and personalities drive discussions toward articulation and analysis that don’t come out looking like ACM portal abstracts. Nevertheless, pick any recommended practice, e.g. headings and logical structure in web pages, and you’ll find rationale, practical hedges for difficulties, and the basis for better controlled and more academically rigorous investigations.
As for the actual academic research communities, there’s a strange legacy of publication practices that make it difficult to track the field. Conference papers disappear behind the ACM Digital Library Portal pay wall. Institutional and individual members of ACM have access that people like this retired researcher have to fork over $200 to reach. Even paying the ransom isn’t enough, as I found it exceedingly difficult to negotiate the search interface in the 2008 time frame, and without response to requests for assistance. In other words, the publication pay wall is an inhibitor to the spread of insight on accessibility from perfectly serious and hard working researchers. How silly is that?
The notable exception I track is the work of professor Richard Ladner at U. Washington research and outreach and his prolific junior colleague Jeffrey bigham, now at U. Rochester. WebInsight project publications are available as readable PDF’s organized well by topics and authors that offer the bulk of their funded research.. These publishable fundable research results are intelligible, related to the standards versions of their science, and especially interesting for a user of the technology attracted to computational thinking, i.e. me. But then the papers reference too often into the ACM portal black hole. Wouldn’t the field progress more rapidly if more people could read such publicly funded publications and appreciate the experimental models being applied?
One additional topic I tracked was an award winning paper mentioned in Professor bigham’s blog on web research, namely the collaborative accessibility project at IBM Japan. However, the best I could find was a useful Youtube video on “social accessibility”. Indeed, with additional perspectives from the grass roots operational social accessibility projects webvism community tagging and solana for cracking the evil CAPTCHA barriers facing visually impaired web users. Indeed, find screen reader and accessibility videos on Youtube including Easy Youtube since Youtube itself is marginally accessible.
another interesting area is accessible apps for apple and android mobile products. There are important engineering lessons here regarding accessibility integration into the architecture, with apple doing it well, Google trying to paste on its talkback capability, and Microsoft admitting it blew off accessibility in its win 7 phones. Google Android accessibility is dubbed the “Model T Syndrome” for not applying state of the art engineering techniques, expecting visually impaired consumers to wait years for reasonable functionality and usability.
Finally, for the serious minded computer theory connection, visit the IBM researcher and leading accessibility guru Jim Thatcher articles on practical standards in business as applied to Amazon.com, Target.com, and many .gov websites. This wealth of robust reasoning and decades of experience are truly awesome.
What’ is the evidence for bad accessibility practice in the computing field?
Here is a test you can perform yourself.
Start the CSED Week test in Web Aim WAVE analyzer. Yes, click that link and now you’ve been seduced into web page testing! Now, look for the link to Partners, click and see the errors there. Keep going for the partner websites, opening and analyzing each web site. Keep going and you will be amazed at the WAVE complaints as the page structures are revealed in their semantic nakedness.
Lots of errors, right??? Let me explain how the errors affect my reading using an interactive access tech “screen reader”, illustrated in recordings in the 2009 post.
- The “missing ALT description” error tells me the web site developers have no clue about accessibility, ignoring the most basic rule. Visually impaired people cannot know what’s in your graphic, why it’s there,if it is decorative or meaningful in context.
- At the higher level of page structure are errors in omitted headings, irregular heading levels, and uninformative headings. The basic problem for someone visually impaired is building a reliable map of a page to transform from a linear search by laboriously tabbing from one HTML element to another. The outline tells me quickly what’s on the page, just like the outline of any well written document. Rarely do I find a web page from a CompSci organization with a good outline, often omitting headings entirely. Another indicator is irregular headings, like H4-H1-H3 which usually indicate confusion among semantics of headers and font-style presentation issues better handled by style sheets.
- Unlabelled form elements can be a show stopper when leading a person and screen reader through a donation or purchase or registration form. The proper HTML has an explicit corresponded between label and element, call, duh, “Label”. Without labels, the user just hears “edit box” rather than “first name edit box”. Forms are really complex , often associated with transaction timeouts and monumental headaches locating and fixing errors. Again, there are good rules for creating usable forms, which the unlabelled form element error tells me the developer has ignored. Do they want my business?
Standalone link names are important for, like headings, a link abstraction allows rapidly skimming for general context and specific refinements.”Click here”, “here”, “read more”, and “learn more” require the screen reader user to search around for context. See post “I don’t want to click here” for a humorous take on this annoying practice.
Webaxe guide to introductions to accessibility and its demo podcasts is a good place to start and also entertaining. WebAim Web Accessibility in Mind also offers an annual empirical analysis of screen reader use and many checklists and guidelines. One caveat is that WAVE, although free and easy, is susceptible to flaws of any static analyzer with false hits, cascading errors, and interpretation of results. However, our tests show that it readily exposes often embarrassing mistakes just waiting for correction. My favorite was a major CompSci blog with hidden text offering Viagra remedies.
While many of these complaints relate primarily to technical communication, there are true design problems related to search tasks, as on the ACM Digital Library, and on large multi-organizational websites like universities. Beyond accessibility, as in supporting technology, are issues of bandwidth limitations, small screen mo vile devices, and user choices on browser script security. While not formalized as in “structured programming” or “object-oriented design”, the recommended engineering practice is “progressive enhancement”, starting from a purely semantic page that covers the basic content and separates presentation layers which a browser can strip away to assure the content is preserved in many contexts. It cannot be emphasized too much: the person using a screen reader is working directly with the semantic content provided by the developer. Designer focus on color, fonts, graphics, and interactivity are truly only “in the eyes of the sighted reader” and may add to but should not obscure the essential page content. and use cases. In other words, the analyses provided by tools like WebAim WAVE and even more important, the mental model in the person using a screen reader provide a favor to page designers by pointing out flaws.
And, is there any good news?
Definitely,when cultural divisions are bypassed, are growing assemblage of tools that enable someone losing vision to maintain their computer skills, provided they can access the training and guides to re-build their own environment. Admittedly, regaining capabilities after vision loss requires months of hard work, willingness to learn new approaches, and acceptance of major life changes.
- AThe free, powerful, open source screen reader NVDA (NonVisual desktop access) competes with established $1000 pricey products on Windows platforms. I truly enjoy, and donate to, the mailing list of international users who daily test and share advice on this Australian generated project. Its developers are blind, primarily using python. These guys deserve a major computing award for their global contributions and professionalism in their twenty-something age ranges.
- The miracle of Text to Speech that activates the hearing sense into an alternative channel into our brains where reading actually takes place. While older people may take more time to rewire their brains after vision loss,it’s truly remarkable that vision can be so minimalist in computer usage, provided accessibility is engineered into our software and information sources. Now, we’re poised to take on the challenge of “information visualization without vision”, seriously a cognitive and technological adventure in literacy and openness.
- Bookshare and NFB News Line downloadable a alternative for print disabled services that brings literally 1000s of great books and daily newspapers to our fingertips in wireless seconds. Never did I imagine I could have such a great store of information to support my retirement book club, lifelong learning, and social entrepreneurship activities period. Materials are read by synthetic speech from DAISY, an XML based, international standard for audio and text content.
- Levelstar Icon Mobile Manager and Docking Station, designed and distributed by a blind engineer, that streamlines my access to Bookshare, NewsLine, Twitter, email, and RSS. Most sighted, and now blind, people will enjoy an immense number of accessible iPad apps, a direction I’ll soon be taking myself.But the Icon sets a high bar of throughput I don’t expect to find on any other device by avoiding screens, using spoken menus and text reading. Another award worthy young technologist for CompSci to learn from.The implementation software for this handheld LINUX box is python and sqlite.
- The #a11y Twitter community of accessibility gurus, blindness advocates,normal blind working folks, and inspiring authors lifts me up every day with humor and an unbelievable syllabus of linked readings. I never expected to find such a “School of Twitter” in social media that could fill my local personal and professional void. I especially value AccessibleTwitter website and demonstration for its common sense, ease of use, and challenge to the big clunky Twitter, which is, of course, the data source and API.
- I’m also grateful for professional opportunities to potentially influence the direction of computing through the CMD-IT Center for Minorities and Disabilities in ITan, its Board of Advisers, and energetic organizer. I’ve written two other posts input to an NSF Task Force on CyberLearning, and hopefully await an insightful report.
Close to home, I appreciate the opportunity to connect with a few local disability professionals and volunteer groups. I’ve seen first hand how a broken rehab system requires enormous cooperation and energy to bring to ever more baby boomers losing vision the tools and experience I managed to find for myself. For all the $$$ spent on research, the chain of referrals and services beyond the medical plateau leaves so many of us just hanging on precariously while trying to find our ways through the inevitable grieving and depression cycles. It shouldn’t be this way in a
wealthy world, requiring not charity but rather planned delivery of existing resources, as related in Jane Brody’s NYTimes articles on vision loss.
The 2011 CompSci Meets Accessibility Manifesto
And that latter point is where my disappointment with the handling of assistive technology and accessibility in computing has lead me to put considerable effort into writing up this critique. We just have to do better in accountability within institutions, domain responsibility for our professionals, and awareness of the depth of effectiveness of our computational thinking methods. Thousands of jobs depend directly on our outcomes for accessibility and quality computing products, plus centuries of better quality of life for everyone sooner or later. Let’s make accessibility meet computer science professionally in 2011.
We’re now at a teachable moment for assistive tech and accessibility in computing education. Everybody has the basic functions in their hands, literally, and for free. Windows users can download capable free open source NVDA screen reader and try testing web pages. Android and IOs users turn on their text to speech and learn credible NonVisual manners of using myriad interesting and useful apps. Come on, anybody can learn to work like a low vision person so the days of descending into the exorbitantly expensive blind ghetto for access tech is over. Anybody from now on who produces inaccessible pedagogical products or sloppy web pages is out of excuses. Your artifacts are testable, the testing tools are available, the engineering practices are wedded with the science of accessibility in standards. and people with sensory limitations like my hazy vision have those access tools at their fingertips, skilled and raring to use products made for mainstream but accessible if properly designed. So, failure to step up to this challenge and do the right thing, which really isn’t so hard and actually is good for business, is a choice of accountability, responsibility, and opportunity.
<The following recommendation was offered at the CyberLearning workshop addressed in the previous post on CyberLearning and Lifelong Learning and Accessibility. The post requires background in both accessibility and national funding policies and strategies.
This is NOT an official statement but rather a proposal for discussion. Please comment on the merits.
Motivation: CyberLearning must be Inclusive
To participate fully in CyberLearning, persons with disabilities must be able to apply their basic learning skills using assistive technology in the context of software, hardware, data, documentation,, and web resources. Trends toward increased use of visualizations both present difficulties and open new arenas for innovative applications of computational thinking.
Often, the software, hardware, and artifacts have not been engineered for these users, unforeseen uses, and integration with a changing world of assistive tools. Major losses result: persons with disabilities are excluded or must struggle; cyberlearning experiments do not include data from this population; and insights from the cognitive styles of diverse learners cannot contribute to the growth of understanding of cyberlearning.
Universal Design Goals
Universal design embodies a set of principles and engineering techniques for producing computational tools and real world environments for persons usually far different from the original designers. A broader design space is explored with different trade-offs using results from Science of Design (a previous CISE initiative). Computational thinking emphasizes abstraction to manage representations that lead to the core challenges for users with disabilities and different learning styles. For example, a person with vision loss may use an audio channel of information received by text to speech as opposed to a graphical interface for visual presentation of the same underlying information. The right underlying semantic representation will separate the basic information from its sensory-dependent representations, enabling a wider suite of tools and adaptations for different learners. This approach transcends universal design by tapping back into the learning styles and methods employed effectively by persons with many kinds of disabilities, which may then lead to improved representations for learners with various forms of computational and data literacy…
Beyond Universal Design as Research
beyond Universal Design” suggests that striving for universal design opens many research opportunities for understanding intermediate representations, abstraction mechanisms, and how people use these differently. This approach to CyberLearning interbreeds threads of NSF research: Science of design and computational thinking from CISE +human interaction (IRIS)+many programs of research on learning and assessment. +…
Essential Metadata Requirements
A practical first step is a system of meta-data that clearly indicates suitability of research software and associated artifacts for experimental and outreach uses. For example, a pedagogical software package designed to engage K-12 students in programming through informal learning might not be usable by people who cannot drag and drop objects on a screen. Annotations in this case may serve as warnings that could avoid exclusion of such students from group activities by offering other choices or advising advance preparation. Of course, the limitations may be superficial and easily addressed in some cases by better education of cyberlearning tool developers regarding standards and accessibility engineering.
Annotations also delimit the results of experiments using the pedagogical software, e.g. better describing the population of learners.
In the context of social fairness and practical legal remedies as laid out by the Department of Justice regarding the Amazon Kindle and other emerging technology, universities can take appropriate steps in their technology adoption planning and implementation.
Policies and Procedures to Ensure Suitable Software
For NSF, appropriate meta-data labeling then leads to planning and eventual changes in ways it manages its extensive base of software. Proposals may be asked to include meta-data for all software used in or produced by research. Operationally, this will require pro posers to become familiar with the standards and methods for engineering software for users employing adaptive tools. While in the short run, this remedial action may seem limiting, in the long run the advanced knowledge will produce better designed and more usable software. At the very least, unfortunate uses of unsuitable software may be avoided in outreach activities and experiments.
Clearly, NSF must devise a policy for managing unsuitable software, preferably within a 3 year time frame from inception of a meta-data labeling scheme.
Opportunities for Multi-Sensory Representation Research
Rather than viewing Suitable Software as a penalty system, NSF should find many new research programs and solicitation elements. For example, visual and on visual (e.g. using text-to–speech) or mouse version speech input representations can be compared for learning effectiveness. Since many persons with disabilities are high functioning in STEM, better understanding of how they operate may well lead to innovation representations.
Additionally, many representations taken for granted by scientists and engineers may not be as usable by a wider citizenry with varying degrees of technical literacy. For example, a pie chart instantly understandable by a sighted person may not hold much meaning for people who do not understand proportional representations and completely useless for a person without sight, yet be rendered informative by tactile manipulation or a chart explainer module.
Toward a Better, Inclusive Workforce
Workforce implications are multi-fold. First, a population of STEM tool developers better attuned to needs of persons with disabilities can improve cyberlearning for as much as 10% of the general population. Job creation and retention should improve for many of the estimated 70% unemployed and under-employed persons with disabilities, offering both better qualities of life and reduced lifetime costs of social security and other sustenance. There already exists an active corps of technologically adept persons with disabilities with strong domain knowledge and cultural understanding regarding communities of disabilities. The “curb cuts” principle also suggests that A.D.A. adaptations for persons with disabilities offer many unforeseen, but tacitly appreciated, benefits for a much wider population and at reasonable cost. NSF can reach out to take advantage of active developers with disabilities to educate its own as well as the STEM education and development worlds.
Summary of recommendation
- NSF adopt a meta-data scheme that labels cyberlearning research products as suitable or different abilities, with emphasis on the current state of assistive technology and adaptive methods employed by persons with disabilities.
- NSF engage its communities in learning necessary science and engineering for learning by persons with disabilities, e.g. using web standards and perhaps New cyberlearning tools developed for this purpose.
- NSF develop a policy for managing suitability of software, hardware, and associated artifacts in accordance with civil rights directives to universities and general principles of fairness.
- NSF establish programs to encourage innovation in addressing problems of unsuitable software and opportunities to create multiple representations using insights derived from limitations as of software as well as studies of high performing learners with disabilities.
- NSF work with disability representing organizations to identify explicit job opportunities and scholarships for developers specializing in cyberlearning tools and education of the cyberlearning education and development workforce.

White paper for NSF CyberLearning Task force
Background: Alex is completing one year service with AmeriCorps Vista as a educational technology specialist for OLLI, the Osher Lifelong Learning Institute at Yavapai College, also working with Northern Arizona SCORE (Service Corps of Retired Executives) in Prescott Arizona. Susan is a semi-retired computer scientist, translating her experiences with vision loss into education and advocacy for web accessibility and adoption of assistive technology. She is a student of philosophy, history, and economics in OLLI, working with Alex and others on a technology task force, and facilitator of courses on social media and technology and society.
To make cyber learning effective in the 21st century, it needs to be available for all populations and people who possess a desire to learn.
Current technology has not lived up to this promise. The younger generations of learners have embraced technology adequately with the help of adventurous teachers and innate ability; however, the older generations of learners have met cyber learning with adversity. Oftentimes, the systems they desire to use are not streamlined enough for adequate adoption. Finally, learners with classic accessibility issues, like poor vision, are ignored when online learning tools are designed. By reaching out to these disadvantaged populations, the whole of cyber learning will improve.
Experience with Cyber Learning for Lifelong Learners
OLLI is nationally supported by the Osher Foundation operating at over 100 U.S. independent locations. Yavapai College OLLI has over 600 members selecting peer directed courses from over 50 subjects during each six week session for fees of $130 for five class sessions per year. Courses are often structured around 1/2 hour lectures from The Learning Company supplemented by facilitator moderated discussions and materials. Diverse fare includes computer training (keyboard, Windows, Mac, Internet, Office, Photoshop) as well as rock and roll, art, health, memoir writing current events,, etc.
We asked: Where does CyberLearning assist OLLI activities and courses? What benefits might accrue
from a good technology platform?
We began to place course materials online after conducting a user survey in the spring of 2010. 87% of respondents in the survey reported having Internet access at home, and 79% reported checking their email at least once a day. The majority of the membership for OLLI did indeed have access to and used the Internet; however, none of the classes were able to readily incorporate cyber learning into their curriculum. A few classes tried using an online learning system, but interest peaked early and soon faded into disuse. With an able-bodied, intelligent, and Internet-ready membership, why was this OLLI unable to engage in cyber learning?
From strongly worded survey comments, we derived a “social contract” that members would not be forced into technology but rather be offered optional technology enhancements. Without clear cut cost benefits, such as reduced printing, or measurable improved learning objectives, we focused on outreach to home bound members, interaction with similar institutions for broader curricula opportunities, repositories and sharing within courses, and archiving institutional pictures and stories.
Existing platforms generally failed to attract interest and use from facilitators despite tutorials and assistance. The first problem is privacy, quite appropriate for repeated warnings of phishing and identity theft, but a barrier to sharing when members do not want a public web identity (Facebook aside). Streamlined and flexible entry is essential especially when courses occur in rapid cycles of six weeks. Forums for sharing are sparsely used because members are involved in many personal and community activities. They spend time as desired, but not required, on outside reading, Googling, and reflecting. A crucial feature of OLLI classes is the lack of tests or assessments during the course. Once grading and competition are removed from the classroom, many online platforms become bloated with unnecessary features. Furthermore, the incentive of using an online classroom to take a quiz or study for a test disappears, and a student must rely on innate curiosity to visit an online classroom.
While email and search engine savvy, OLLI members are not cognitively familiar with the models of forums, blogs, wikis, or tweet streams, and because of this, we are faced with introducing both new models and complex platforms together. After some experimentation and testing, we settled on using EDU 2.0, a rapidly growing U.K. based company with a reasonable business model and support, for an online classroom. We also partnered with another interesting venture in an Australian-based U3A, University of the 3rd Age, which offers self-paced courses and repositories available for facilitator adaptation at similar lifelong learning institutions. Although the OLLI membership is predominantly White, well-traveled, and professionally diverse, international thinking and contacts can offer many new opportunities for our OLLI, like an international book club.
Meanwhile, OLLI’s monthly newsletter has been adapted to appear on a WordPress blog with future plans for moderated forums. We are also actively using the college’s interactive TV classroom connection to offer distributed courses to our sister OLLI, expanding their course selection in the process. A long term goal we have is to host joint OLLI Internet-based courses that would take advantage of the country’s pool of retired expertise. However, the really tragic goal of reaching homebound elders in a community lacking public transit remains primarily a function of offering shared rides and a reliance on volunteers working within the public library.
Perhaps a more important goal is “Learning Cyber” or learning “by osmosis” and how social networks and cyber learning are changing our information practices. Why would any sane person use Twitter? How does a grandparent respond to pressure to participate in Facebook in order to see pictures, or monitor children, grandchildren, and vice versa? Does Google always provide correct information? What happens when newspapers open articles to potentially unpleasant community commenting? What is RSS? How does one critically check facts and correct chain emails with political misinformation? Facing complex interactions with Social Security websites, how does one upgrade their skills for PDF, forms, and chat help? Who wrote Wikipedia? When can You Tube, BigThink, and TED supplement the History and Discovery cable television channels? What are our real privacy rights regarding Google, Facebook, and online retailers? Institutions like OLLI provide an informal setting for increasing and assessing the skills of individual Cyber Learners. Our technology initiatives may be more effectively directed at exposure and bridging generations in both technological and chronological senses.
For the continuing improvement of a national Cyber Learning movement, we suggest researchers and developers incorporate, sooner rather than later, constituents from learning environments such as OLLI and similar institutions. We also recommend investigating the educational and technological practices of the two international sources we found most attractive, EDU 2.0 and U3A. The above experience should provide insights into and questions about cross generational Cyber Learning, which will benefit the movement as a whole.

How Attention to Accessibility Can Improve Cyber learning
Attention to accessibility for persons with disabilities should be an immediate objective for educating *ALL* constituencies who touch any aspect of Cyber learning. Consider “accessibility” as the practices and technology that enable persons with disabilities using “assistive technologies” to participate fully and comfortably in CyberLearning.
Indeed, there is no choice if the Departments of Justice and Educations follow through on their “Dear College President” letter regarding
fairness in applications of emerging technologies in academic environments. “Accessibility” here means that devices and web sites must support assistive technologies commonly available through special education channels and increasingly appearing in mainstream markets: Screen (text-to-speech) readers, alternative input/output devices, networked tablet readers such as Kindle and iPad, and possibly lab instrumentation and pedagogical software.
As we argued regarding senior learners, citizens and markets must be served by people who differ in many aspects of physical and mental activities. Education workplaces and curricula must adapt to concepts of universal design ancultural diversity.
Fortuitously, adapting to accessibility offers a systematic way of expanding and analyzing design tradeoffs that benefit far more than persons with disabilities. Think about curb cuts originally for wheelchairs and now beneficial to baby strollers, bikers, inattentive walkers, and luggage cart users. In web environments, standards: address usability for persons using screen readers, also causing difficulties for many mobile device user;, facilitate interoperability of browsers and other user agents; and help manage costs of do-overs and long term maintenance.
For CyberLearning to reach its potential and broaden participation, attention to accessibility is not only overdue and inevitable but also a chance to refresh underlying technology as a CyberLearning experience in itself.
1. Web standards such as WCAG 2, provide a fledgling “science of accessibility” in the form of definitions, principles, experimental results, and field trials. Standards and theories evolve by employing high quality peer reviews, broad community input, extensive documentation,continuing debate in blogs and on Twitter, and increasing adoption earlier in cycles of HTML adoption. Professor Richard Ladner’s group at U. Washington contributes in depth traditional graduate and capstone education experiences, experiments, and publications, yielding cohorts of researchers also involved in outreach to K-12 students with disabilities. Furthermore, an engineering paradigm is emerging as “progressive enhancement” supported by static analyzers, and free operational tools (NVDA screen reader and VoiceOver on Macs). This science is a rich area for computational thinking.
2 University and professional organization web sites are often exquisitely poor examples of attention to accessibility, attested to by a recent NSF-funded study, ironically locked behind a professional society pay wall. Why are many Cyber learning organization web sites so bad? Accessibility simply is not a requirement, e.g. look up your own organizational accessibility statement. Is there one, is it followed, who is responsible? Ok, so academics don’t have time to learn or enforce accessibility theory or practice. But, is it acceptable to turn away Students who can otherwise function well in society but face extra barriers in STEM? and where will accessibility aware CyberLearning developers come from? Ouch, should organizations such as NSF and MIT promote inaccessible pedagogical tools such as Scratch?
In fact, we are not talking major engineering feats, but rather well structured pages as in good technical communication, a few lines of code that make forms into relational structures and pictures into captioned objects. The principle is general use of POSH (Plain Old Semantic HTML) from straight text HTML preserved through styles and fancy interactions topped off by seconds of automated compliance analysis and minutes of insightful execution of use cases. However, accessibility in pedagogical software definitely requires fundamental adoption of hooks and interfaces provided by system vendors.
Think of this change as one small step in technical communication and one giant leap forward in understanding and improving human learning performance.
3. Practically speaking, curricula can only have accessibility grafted onto courses and tools rather than taught as separate subjects. But creative and active learning can come into play: interviewing local ADA specialists for requirements and projects; turning off displays and browsing with a screen reader; estimating costs of retrofitting for omitted accessibility requirements; analyzing risks of lost markets and litigation; adding features suggested by audio supplement or alternative output and input channels; ethics and accessibility addenda to assignments. People who love game controllers and touch screen mobile devices should dig these exercises.
4. Specific interventions must be attempted starting with faculty awareness and introduction to the science of accessibility and its economic importance as well as social fairness. Suggested activities: accessibility seminars at educator gatherings; forced overhaul of professional and government sites to match .com and other .gov levels; design contests for students to makeover and create new information resource sites to meet the grand universal design challenge; audit of pedagogical tools, including textbooks, for universal learning objectives encompassing accessibility; release of all disability related publications now imprisoned beyond professional society pay walls; increased awareness of accessibility as a job and professional speciality; recognition of assistive tech as part of user interfaces; rubrics for POSH in technical communications. …
On a personal note, many avid learners gain vision rehabilitation facilitated through a vibrant online culture of blogs and podcasts on emotional, social, education, and technical topics. Visit this world yourself: book clubs and interactive demos at AccessibleWorld; product demos by individual users at BlindCoolTech; more demos and discussions at ACBRadio; and now a community of #accessibility and #a11y gurus and users on Twitter. Off the mainstream, but taking full advantage of CyberLearning while casting a wider net to newly disabled individuals offers a testimony to spontaneous online learning.
The Data Literacy Challenge
Finally, while the above complaints and suggestions are largely remedial, one clear challenge is the equal visualization” of information and data. Portfolio pie charts, rainfall tables, stimulus recovery expenditure maps, timelines, … are all essential for citizen participation and difficult for visually impaired people. Difficult, yes, but can alternative and multiple ways of channeling data into brains be accomplished through the adapted and flexible recognition and reasoning processes developed by visually impaired thinkers such as scientists and engineers? Can these new models of information and modes of interaction then benefit people with less analytical background or resistance to data driven reasoning?Designing cyber learning for the temporarily fully enabled may not only limit those currently working with disabilities but fail to build upon the unique experiences of and qualities of disabilities which we all have intermittently and eventually.

The good about disability
background: print-disabled and legally blind for five years into retirement.
- I love technology.And, wow, does disability open your eyes, so to speak, or maybe it’s our ears and brains. For example, I carry my entire rebuilt
library of over 1000 DAISY books from bookshare.org on a lavaliere booksense along with many GB of podcasts all downloaded via Levelstar Icon Mobile Manager and Docking station. Better reading now than ever in my life, thanks to this technology and the Internet.
- I meet many cool people through my disability. The virtual community of #a11y and #accessibility on Twitter are my gurus and heroes, loading up my browser tabs with good articles and forging new links in my mental map of the field. In physical life, I’m the lady with the white cane to ask about
- retired and still kicking, my disability + technology background + learning regime have given me a focus for hours a day of accessibility activism as well as outreach. “Turning lemons into lemonade”, they say, but I just call this a lifetime bonus for as long as I can hold it together.
The bad and Other stuff I’m Too Mad To talk about
My very own profession sucks at accessibility and supporting disabilities. As a computer science educator, researcher, developer, and manager I followed the trends of not noticing disabilities, and got some immediate karma. You know where all those unaware developers are coming from? Our very own computer science accreditation and technical programs.
And even inexcusably worse are
the leading professional organizations, such as ACM and its decrepit website. Personally, I coughed up $200 for access to a pay wall of articles for my memoirs and on accessibility. A painfully usable digital library interface did not elicit requested help, back channel messages about accessibility problems were ignored, and all I got was a lifetime membership offer and more renewal notices. The ACM motto: “Of course, accessibility is important. But, we don’t know anything about it. Now, please go away”.
- If you have or expect a vision problem, don’t move to a place without public transportation! What a difference in my life if only a bus scooted along
the major crosstown connector street a block from my house! I can take taxis when I don’t have regular driver available, can also ask for rides, but the loss of independence is a daily demoralizer. Worse, when I do get out like a regular pedestrian, drivers enter crosswalks to scare me and I know half the drivers are talking or otherwise not paying attention.
- Trying to establish new relationships with fuzzy faces is challenging. At least, it’s easier now that I’m out in the open about vision loss compared with prior years of hiding, but it’s still saddening not to know the details of my lifelong learning classmate features. Like everybody around a table is a talking space suit, I struggle to remember names to connect with voices and body outlines. But, at least I’m really working on people connections, finally.
