Accessibility of Learning Management Systems
Like many of the products we use every day, most learning management systems were not originally designed to work universally—to work for all users, regardless of ability. Though the situation is improving rapidly, there is still a considerable lack of understanding and applying the concepts of universal design during the development process in product design. Most often, developers make assumptions that include users can see the screen, the mouse is the main tool for navigation, visual alerts can be used as signals, and that skimming the screen in a random fashion will result in logical associations to facilitate easy, intuitive use of online learning environments. The fact that a blind person may be a student using online learning tools usually meets with surprise. Yes, blind students are trying diligently to use the same tools the sighted world takes for granted but usually with great difficulty.
Common Accessibility Issues with Learning Management Systems
Learning management systems (LMS) consist of various features that could cause accessibility problems for students and teachers with disabilities if they are not designed with accessibility in mind. Depending on the features enabled for a course, a student with a disability could find that participating independently and effectively is nearly impossible. Some LMS features are more problematic than others such as Quiz, Chat, or Wikis. The following table shows accessibility issues associated with commonly used features across various LMS's. All of these accessibility issues can be easily resolved if they are considered upfront or incorporated in design modifications. If you are an LMS product developer, we urge you to consult the Appendix section for practical Accessibility Design Considerations.
LMS Feature |
Accessibility Issue |
|---|---|
Assignments:Allows teachers to collect work from students, review it and provide feedback including grades. Students can submit any digital content (files), including for example, word-processed documents, spreadsheets, images, audio and video clips. Assignments don't necessarily have to consist of file uploads. Alternatively, teachers can ask students to type directly into an online text assignment. There are also an offline activity assignment which can be used to remind students of 'real-world' assignments they need to complete and to record grades for activities that don't have an online component. |
|
Blogs:A form of online journal used by millions of people around the world for self-expression and communicating with family and friends. Blogs are usually organized as a chronological series of postings created by the author of the blog. Blogs usually are written by one person, although some blogs can be authored by groups of people. |
|
Chat:Allows participants to have a real-time synchronous discussion via the web. This is a useful way to get a different understanding of each other and the topic being discussed – the mode of using a chat room is quite different from the asynchronous forums. The Chat module contains a number of features for managing and reviewing chat discussions. |
|
Choices:The teacher asks a question and specifies a choice of multiple responses. It can be useful as a quick poll to stimulate thinking about a topic; to allow the class to vote on a direction for the course; or to gather research consent. |
|
Databases:Allows teacher and/or students to build, display and search a bank of record entries about any conceivable topic. The format and structure of these entries can be almost unlimited, including images, files, URLs, numbers and text among other things. |
|
Forums:Successful communication and community building; common area for students to come together and discuss unlimited topics, including social activities and educational ideas. |
|
Glossaries:Allows participants to create and maintain a list of definitions, like a dictionary. |
|
Lessons:In a lesson page's simplest form, the student can select a continue button at the bottom of the page, which will send them to the next page in the lesson. Lesson can deliver content in interesting and flexible ways to each student, with no direct or time sensitive action required by the teacher once the lesson has been created. Each answer to a question may send the student to a different series of pages in the lesson. The teacher's response and the next page the student will see has already been thought out by the teacher. |
|
Quizzes:Allows the teacher to design and set quizzes consisting of a large variety of Question types, among them multiple choice, true-false, and short answer questions. These questions are kept in the course Question bank and can be re-used within courses and between courses. Quizzes can allow multiple attempts. Each attempt is automatically marked, and the teacher can choose whether to give feedback and/or show the correct answers. |
|
Resources:Pdf documents must be created accessible. Scanned documents that become pdf's are NOT accessible—they are treated like images. Only tagged pdf documents are accessible to screen reader programs. |
|
Surveys:Provides a number of verified survey instruments which have been found useful in assessing and stimulating learning in online environments. Teachers can use these to gather data from their students that will help them learn about their class and reflect on their own teaching. |
|
Wikis:A collection of collaboratively authored web documents. Basically, a wiki page is a web page everyone in your class can create together, right in the browser, without needing to know HTML. A wiki starts with one front page. Each author can add other pages to the wiki by simply creating a link to a page that doesn't exist yet. |

NOTE: The "Filling out Forms" issue discussed in the table consists of at least two components or separate HTML elements: the input field and that field's label. A typical example of this is a text box in which a user is expected to enter a first name. If the text box is not properly "labeled", the visually impaired user cannot identify the purpose of the text box. Should he/she enter a first name, last name, or birth date? Images should never be used as labels (e.g. image of a telephone for the phone number field). Labels should be clearly identified using the "label" element.
Case Study: Cal State Universities
Due to the increasing awareness about institutional, state, and federal accessibility requirements, more and more educational institutions are requiring minimum accessibility standards in their RFPs for purchasing LMS's and do not rely on a company's accessibility statement or VPAT (Voluntary Accessibility Product Template). Instead external or internal reviewers are performing independent studies on accessibility of the product in question or they refer to already existing accessibility evaluations by other entities or peer institutions.
In the spring of 2008, the California State University Chancellor's Office issued an RFP for a Master Enabling Agreement (MAE) for Learning Management Systems to be used on the CSU campuses. Accessibility was one of the criteria used to evaluate the proposals. An independent accessibility evaluation was conducted on each of the five finalists bidding on the RFP.

As a result of the accessibility evaluation, only two vendors, namely Moodle and Angel, were accepted and named in the Master Enabling Agreement (MAE). Desire2Learn and Blackboard did not pass the accessibility evaluation.

A new RFP was issued in October 2008 using the same accessibility requirements with the expected result to be published in Spring 2009. Due to a lack of internal resources, CSU decided to use an external company for the re-evaluation. Meantime, both Blackboard and Desire2Learn intensified their interaction with their respective accessibility collaboration groups, dedicated development resources, and tried aggressively to address the accessibility issues in some of the commonly used features. They partially redesigned them with the help of their accessibility collaboration partners (see below). This resulted in passing the CSU accessibility requirements and entering the Major Enabling Agreement.
Background on University of Illinois Collaboration Initiative
In 2004 the University of Illinois at Urbana/Champaign along with the University of Minnesota and Ohio State University started a collaborative approach to address accessibility issues at institutions of higher learning. This new and innovative way of addressing accessibility brought higher education specialists and commercial vendor product developers from WebCT, Blackboard, Desire2Learn, Ebsco Publishing, Ex Libris, and a few more to work collaboratively with the goal of improving accessibility. This group continues to promote the idea that the best place to address accessibility and usability is in the design process and not after the fact when the product is about to be released.
Survey Reveals the Experience
It is important to note that while the accessibility improvements in Blackboard and Desire2Learn resulted in re-entering the CSU Major Enabling Agreement, it does not mean that they are fully accessible and usable by students or teachers with disabilities. A December, 2008 study released by the American Foundation for the Blind, indicated the most important and necessary features of online educational tools presented significant problems for those using assistive technology such as screen reading or screen magnification software. Nearly one third of respondents who used assistive technology to access online educational tools reported the experience as unreliable/inconsistent or no successful use/access. Open ended questions gave respondents the opportunity to share their personal stories. In nearly every instance, respondents indicated features that were inaccessible. http://www.afb.org/Section.asp?SectionID=3&TopicID=138&DocumentID=4492
