WeBWorK accessibility projects

Hi,

There are a number of centers using WeBWorK that are interested insuring that our online homework system is accessible, that it meets universal design goals and can be used as widely as possible.  Using MathJax to represent mathematical equations has been a big boost in that direction.

Here is a post from Portland Community College one of the active centers working on the accessibility aspect of WeBWorK.  The summer MathFest conference will be held in Portland, OR in August 7-10, 2013 and there are tentative plans to hold a code camp in Portland devoted to WeBWorK accessibility on the three days proceeding MathFest. Details are still being worked out but if you are interested or have ideas or suggestions email me or Alex Jordan at Portland Community College.

Below is the report.

Making Math More Accessible at Portland Community College

At Portland Community College (PCC), Disability Services (DS) is tasked with ensuring the accommodation process unfolds appropriately across and throughout a district serving approximately 90,000 students per year, 50,000 of whom are seeking credit.  In recent years the options for curricular content format and delivery have changed considerably, bringing new barriers, but also new opportunities for making math more accessible. Many courses are now designed around online engagement points that tap vast databases, generating individualized browsing sessions any time of day or night, giving users valuable and almost instantaneous feedback. While Disability Services can convert known problem sets ahead of time, and hire aides to serve as readers and scribes, it is not practical, nor does it provide equally effective communication, to try and address barriers on the fly.

The truth is that while there will always be some need for individualized accommodation, for example creating tactile representations of graphs, there is much that can and should be done on the front end to minimize the need for manual adjustments. If online engagement points comply with established Web Content Accessibility Guidelines and use proper structural markup for math content, users who rely on text to speech, braille translation, magnification, or voice recognition, can still typically get what they need. The content is built for flexibility. However, when these best practices are not honored, there is often no way DS professionals can ensure equally effective communication. We can’t reach behind the firewall and “fix” content by adding descriptions to images, putting equations into MathML, or redesigning the interface to ensure keyboard navigation.  What DS can do, and should do, is partner with Faculty, Instructional Support, and other stakeholders to help the institution recognize our shared responsibility to ensure equal access through ethical course design and curricular material adoption processes.

At PCC, online instructors develop their own courses within the learning management system. They choose the color and formatting of their text, the media, publisher materials and third party web sites and applications to use in their courses. And since the spring of 2012, all new and revised online courses paid for development by the Distance Education (DE) department are reviewed for accessibility. But how is an instructor supposed to know what’s accessible and what isn’t?

The Distance Education department has seen accessibility as an area that instructors need support. To that end, they hired an Accessibility Advocate who trains instructors and reviews courses for accessibility. And last fall (2012) the DE department co-sponsored with the Math department, two math faculty in their study of accessible mathematics. This subject specific study was so successful that the DE department hopes to emulate it with other academic program areas, especially in the STEM fields.

Math faculty members, Scot Leavitt and Chris Hughes investigated both the accessibility of content generated by the instructor and that which is delivered by homework management systems. In addition to studying commercial homework management systems such as MyMathLab, they ran a battery of accessibility tests (assisted by Math faculty Alex Jordan) on WeBWorK. The results from the WeBWorK experiments were superb- the screen reader JAWS was able to navigate easily around the web page and, most importantly, could read even the most complicated mathematical expression with the greatest of clarity.

WeBWorK is currently the only math homework management system fully endorsed by the Disability Services Office at PCC, and they are providing strong support in the creation of a dedicated server to host it. The server should be fully functional by the end of Summer 2013, and ready for wide-spread use across the college at some point within a year. Supporting WeBWorK in this way allows PCC to provide instructors with an alternative to commercial offerings that have known accessibility issues. By establishing our own WeBWorK server we ensure our community has access to a powerful homework management system that is more usable to more people more of the time. It also provides the institution with a means to ensure access for students who are enrolled in sections built around inaccessible engagement points by providing an equally effective alternative.

  1. It is strongly recommend that your electric wheelchair or scooter be equipped with "gel cell" or "dry cell" batteries. "Wet cell" batteries, like the one used in automobiles, are strongly discouraged since airlines must separate these from your scooter or wheelchair and store them in a leak proof container.

  2. INTERNATIONAL CONCEPT OF WORK FROM HOME
    Work from home theory is fast gaining popularity because of the freedom and flexibility that comes with it. Since one is not bound by fixed working hours, they can schedule their work at the time when they feel most productive and convenient to them. Women & Men benefit a lot from this concept of work since they can balance their home and work perfectly. People mostly find that in this situation, their productivity is higher and stress levels lower. Those who like isolation and a tranquil work environment also tend to prefer this way of working. Today, with the kind of communication networks available, millions of people worldwide are considering this option.

    Women & Men who want to be independent but cannot afford to leave their responsibilities at home aside will benefit a lot from this concept of work. It makes it easier to maintain a healthy balance between home and work. The family doesn't get neglected and you can get your work done too. You can thus effectively juggle home responsibilities with your career. Working from home is definitely a viable option but it also needs a lot of hard work and discipline. You have to make a time schedule for yourself and stick to it. There will be a time frame of course for any job you take up and you have to fulfill that project within that time frame.

    There are many things that can be done working from home. A few of them is listed below that will give you a general idea about the benefits of this concept.

    Baby-sitting
    This is the most common and highly preferred job that Women & Men like doing. Since in today's competitive world both the parents have to work they need a secure place to leave behind their children who will take care of them and parents can also relax without being worried all the time. In this job you don't require any degree or qualifications. You only have to know how to take care of children. Parents are happy to pay handsome salary and you can also earn a lot without putting too much of an effort.

    Nursery
    For those who have a garden or an open space at your disposal and are also interested in gardening can go for this method of earning money. If given proper time and efforts nursery business can flourish very well and you will earn handsomely. But just as all jobs establishing it will be a bit difficult but the end results are outstanding.

    Freelance
    Freelance can be in different wings. Either you can be a freelance reporter or a freelance photographer. You can also do designing or be in the advertising field doing project on your own. Being independent and working independently will depend on your field of work and the availability of its worth in the market. If you like doing jewellery designing you can do that at home totally independently. You can also work on freelancing as a marketing executive working from home.

    Diet food
    Since now a days Women & Men are more conscious of the food that they eat hence they prefer to have homemade low cal food and if you can start supplying low cal food to various offices then it will be a very good source of income and not too much of efforts. You can hire a few ladies who will help you out and this can be a good business.

    Thus think over this concept and go ahead.
