Ensure that readings and instructional materials are fully functional with commonly used accessibility tools (e.g., refreshable braille displays, screen readers, and screen magnifiers)

The most commonly mentioned barrier is nonaccessible course materials, including required readings and instructor-created content formatted in ways that limit use. Two federal statutes, the Americans with Disability Act (ADA) of 1990 and Section 504 of the Rehabilitation Act of 1973, require colleges and universities to ensure that students with disabilities are provided accessible course materials. If materials selected for the course do not meet the criteria, students contact the Disability Services Office (DSO) on campus, which is required to find accessible alternatives. This entails requesting accessible versions directly from the publisher or the instructor or scanning written materials into accessible versions. Reading materials in PDF format is a particular challenge. Providing course materials in this format is not sufficient to ensure accessibility; settings for PDF files are sensitive, and the files often are saved in a format that cannot be processed by screen readers. In addition, scans of weathered or annotated material can lead to difficulties with readers and magnifiers. Determining whether a PDF file is saved in an accessible format also can be a challenge. ^{Footnote 1} The DSO works with faculty to ensure the accessibility of course materials, in advance, and can reformat files for use with screen readers and magnifiers if necessary.

Consideration of accessibility extends beyond course readings to include instructional tools that students are required to use. For example, many standard statistical software packages used in research methods courses (i.e., SPSS and Statistical Analysis System [SAS]) are not compatible with assistive technologies. The R software package, when used in terminal mode, is accessible and provides an equivalent experience compared to other statistical-analysis software (Godfrey Reference Godfrey2013). Unfortunately, using R in terminal mode removes the simplicity of the graphical user interface that makes adoption of statistical software packages appealing.

An instructor must decide whether to (1) adopt R in terminal mode for all students, or (2) use it as an accommodation for students with visual disabilities and a graphical-user-interface–based platform (e.g., SPSS, SAS, Stata, and standard R) for other students. The first approach likely requires a major course redesign and adds an increased level of difficulty to the statistical-analysis portion of the course. The second approach requires the instructor to teach two different approaches in the same course. I continued to use SPSS with my class and converted assignments to R in terminal mode for the blind student. This solution was less than ideal because the student was isolated from the rest of the class. In the last four weeks of the semester, we met for weekly one-on-one sessions to replicate course material for use in R. The student expressed feelings of being ostracized, but it was the only way to ensure an equivalent statistical-analysis experience in that semester. ^{Footnote 2}

Recognize the diverse communication needs of students by incorporating multiple delivery methods

This principle is best summarized by a student who stated, “The more descriptive a faculty member can be in their lecture presentations, the better it is.” Instructors often overlook the fact that images included in course materials cannot be processed by screen readers. This fails to recognize an important attribute of communication that has a significant impact on students with visual disabilities. Any image (e.g., a photograph, a drawing, and a graph) must be annotated to provide a description that can be read through the screen reader. In both Word and PowerPoint, this is accomplished by right-clicking on the image, selecting Format Picture, and then selecting Alt Text. The instructor gives the image a descriptive title and then explains the image in the text box. In class, the instructor should provide detailed descriptions of any image being presented. For example, reading aloud all labels and numbers in a table, each variable, and numbers and operators in an equation, as well as providing all relevant origin and data-point labels of a graph, may be required for full comprehension by students with visual disabilities.

Instructors also should provide digital versions of annotated images in advance of class, which allows students to use screen magnifiers or screen readers on their laptop to access the image information during the lecture. Otherwise, students with visual disabilities are unable to communicate and participate in the same manner as other students. If an electronic copy is not provided, the student must have the physical document scanned, which further delays access to the information. This can be a problem with activities such as “pop quizzes.” If the instructor neglects to provide an electronic copy of the quiz before class begins, it is impossible for the student to complete the quiz in a timely manner. Simply administering the quiz by reading the questions aloud to all of the students, as opposed to printing the quiz, alleviates this problem without providing an accommodation. Considering the communication attributes that affect the transmission of instructional material to students is as important as the material itself.

Ensure that instruction is accessible in formats that provide identical or, at a minimum, equivalent usage for students with different abilities

Although a digital textbook may be identical to the printed version, the supplemental materials often are not accessible. These materials include problem sets, interactive-learning modules, supplemental readings, and chapter summaries. Students in the focus group noted that alternatives provided by faculty are not always equivalent and often are of lower quality than the content created in synergy with the textbook.

Even more common than the textbook barrier, students mentioned that faculty reliance on visual-presentation tools (e.g., PowerPoint) to provide class lecture notes works poorly with screen readers and magnifiers. Whether the text is accessible or presented in the same order through assistive technology depends on file layout and formatting. Running the PowerPoint Accessibility Checker ensures compatibility. ^{Footnote 3} Word files are more reliable for use by students with visual disabilities, and providing course materials in both formats is an easy way to ensure access. ^{Footnote 4}

Vary instructional methods to allow students with diverse learning styles and abilities to demonstrate mastery

Providing accessible material ensures that students with visual disabilities consume the same content as other students. However, the use of screen readers and screen magnifiers changes the way that a student interacts with the material. Two students in the focus group expressed frustration with classes that relied on traditional research papers and open-book exams as the primary—and, in one case, the only—assessment of student performance. As they noted, “Skim reading using a screen reader is not possible” and “…taking notes [while] modifying the document with the screen reader can cause bad crashes.” The mechanics of completing tasks that require the search and reference of written texts is a difficult and time-consuming process. Nevertheless, open-book exams and traditional term papers should not be avoided. In fact, in many cases, they are the most appropriate assessment instrument for mastery of course objectives and goals. However, by using a combination of instruments within a course (e.g., oral presentations and group projects), an instructor may provide all students—especially those with disabilities—multiple ways to demonstrate competency.

Anticipate variation in individual student learning pace and adjust timing of assessment and feedback accordingly

The most common accommodation given to students with visual disabilities is additional time to complete exams and assignments. Political science courses—research methods in particular—often require students to search for information using electronic databases. Although they are improving in terms of accessibility, many are not designed to work well with assistive technology. Even databases that meet the requirements provide search results that include a large percentage of inaccessible PDF files. Students with visual disabilities must choose between skipping the results or taking the time-consuming steps of downloading and rescanning them into an accessible format before they can assess whether an article fits their needs. The basic mechanics of using assistive technology to search and sort through the results provided by electronic databases is a frustratingly slow and difficult process. In my course, the time required for a blind student to satisfactorily complete the search-and-sort portion of the assignment equaled the time allotted for the entire assignment. To complete the full assignment, the student needed most of the semester rather than only the last six weeks. Another option was to have the assignment modified to reduce the search-and-sort portion.

It is important to provide flexibility in the timing of assignment submissions for students with visual disabilities. Breaking complex assignments into a several shorter components allows students to better manage their time. It ensures that they have the necessary time to complete all assignments, and it also provides the instructor with more opportunities to observe the students’ learning progress and provide feedback.

Plan and deliver instruction in a straightforward and predictable manner that eliminates unnecessary complexity

A poorly planned and unorganized course negatively affects students with visual disabilities to a greater degree than other students. “The biggest problem is if the professor is not prepared to have me in class.” If an instructor has not planned the course to be accessible to the student with visual disabilities before the semester begins, it is difficult to procure the required accommodations. “[If] a problem [with accessibility] comes up, and there isn’t a plan for how to deal with it, you can end up a week or more behind,” stated one of the focus-group members.

Posting course materials online in advance allows instructors and students to identify and address accessibility problems before they are encountered in class. Maintaining a content-rich and well-organized Learning Management System (LMS) course page is a simple way to achieve this. Most LMSs (i.e., Blackboard and Moodle) are compliant with current accessibility requirements of the Rehabilitation Act and the ADA (US Department of Education 2011). However, the accessibility of content placed in the LMS depends on the instructor. An example of unintentionally undermining this accessibility was referred to by a student as “The PDF Inception Problem.” If a PDF version of the syllabus is posted with embedded links to PDF versions of readings, opening the files from within Blackboard often crashes the assistive technology, which then requires a system reboot. A simple and intuitive LMS layout in which content is provided through standalone links avoids these types of problems and makes finding information easier for all students.

Provide coursework in ways that reduce the amount of nonessential effort

This principle encompasses both physical effort (e.g., standing for extended periods in a lab or classroom) and mental effort (e.g., studying amid distracting background noise). Nonessential physical or mental effort leads to fatigue and detracts from the learning experience. One technological source of nonessential mental fatigue mentioned by the focus group was the faculty requirement to use software and/or web services (e.g., Dropbox and Google Drive). Although these services, commonly used to facilitate group projects, are technically accessible using assistive technology, they are bug-prone and often lose connections, which results in lost data and continuous reboots. This does not necessarily prevent students from completing assignments; however, it causes them to expend more energy than necessary. As one student noted, “…use of specific programs should not be mandatory… [faculty] need to allow flexibility.”

Promote an atmosphere that shows a willingness to meet the instructional needs of all students and encourages students to convey their needs

According to students in the focus group, the instructional climate of the classroom is largely determined by the willingness of an instructor to openly communicate and engage with a student about expectations and plans for accomplishing course goals. The ADA and the Rehabilitation Act require that accommodations be provided only to students with documented, qualifying disabilities. Formal notification typically is provided to faculty through a letter from the DSO on or before the first day of class. The letter provides details regarding the qualifying disability and offers suggested accommodations. It should be perceived as the starting point of a discussion on how best to meet the needs of the student while also maintaining academic expectations. “It is not unusual for instructors to be unaware of the needs of students with disabilities or to perceive academic adjustments for these students (such as extended time or note takers) as negatively affecting the academic integrity of the assignment or of the course… [and] may be viewed as an ‘unfair advantage’ to a student” (US Department of Education 2011). Disabilities are not necessarily openly discussed by faculty and students, which can negatively affect the experience of both parties. A student in the focus group noted that there are benefits to an honest conversation with instructors, even when they are not interested in providing any accommodation. “It is better off for both of us; the professor can teach it the way he wants and I can drop the class and take it with someone else.” Faculty should be open to these discussions when the need arises. It is always important to communicate with students; however, the more technologically rich the course, the more important it is to make contingency plans for accommodation if accessibility problems arise. It is critical to have this conversation early in the course to ensure that the class maintains the required rigor for all students.
