HOW DO I ADDRESS ACCESSIBILITY CONCERNS?
Duke University is committed to providing an accessible and welcoming learning environment for all students, including those with disabilities. General information about accommodating students with declared disabilities is available from the Duke Disability Management System. This guide describes how you can make design choices in your course to maximize accessibility for all students regardless of the course delivery format.
Making documents accessible
Choose document file types that can be accessed by all students. This generally means that you should avoid PDF documents since they typically do not work with screen readers. Instead, use readable and searchable formats such as Google Docs, Microsoft Word or Box Notes. This applies to all written course materials including the syllabus, lecture notes, slides and required readings. If you want to use an excerpt from an existing text, try to find an online copy instead of scanning it or using an image file. You can get help finding online texts by contacting the Duke Libraries. You can easily convert almost any type of existing file to an accessible format using this online Document Conversion Tool.
Design your course documents for accessibility. When you create materials for your course, think about whether your design choices make it easier or more difficult for students to learn from those materials. Some best practices for designing accessible materials include:
- Use contrasting colors, such as dark blue text and light yellow backgrounds, instead of only shades of a single color.
- Avoid color combinations that are difficult for people with colorblindness to distinguish, such as red and green.
- When designing a graph or chart, each element should have both a different color and a second informational cue such as a distinct pattern; if a student cannot see the color cue, they can still understand the information.
- Select fonts based on readability, and use at least a 12-point font for most documents.

Making videos accessible
An accessible video needs to have three things:
- A transcript
- Audio description
These allow people to access the content by watching the video, reading the transcript or captions or listening to the audio. There are two different places where you should evaluate whether the video-based content in your course is accessible: real-time learning experiences held over video and video content that students watch on their own.
Zoom is an accessible platform for real-time video sessions. Zoom has many integrated features that allow students with disabilities to customize their experience to meet their needs. These include integration with closed captioning readers, full keyboard shortcut support and screen reader support. We recommend using Zoom for class meetings, group project meetings and office hours in online and hybrid courses.
If you plan on sharing your screen during a Zoom class meeting, you can provide students needing accommodation the relevant files or websites you will be accessing during class. This way, these students can access these files and websites using a screen reader while you use the same materials during class.
You can also use Zoom to record videos for your students to watch. This allows you to take advantage of Zoom’s built-in accessibility features. Be sure to turn on Zoom’s “automatic transcription” feature to create an automatic transcript of your video. If a student in your course has a documented condition that requires captioning, the Disability Management System office will contact you to arrange for human-generated captioning of your content.
Check third-party videos for accessibility. If you are asking students to watch videos that you did not create, check that the videos do not create accessibility barriers for students. For example, while most students may be able to figure out what is being said in a video with poor sound quality, students with hearing disabilities may be unable to do so. Avoid using any content that could exclude some students from fully participating in an activity or lesson.
Making learning activities accessible
If you think about accessibility at the outset when you design learning activities, you will not have to make substantial changes to accommodate students in the future. This also increases the likelihood that you can use the same learning activities in a variety of course formats.
Select accessible platforms for student activities. Duke’s Learning Innovation teaching consultants and learning experience designers can recommend accessible learning platforms and technology tools for most course activities. In addition, all the tools that we recommend and support have been evaluated to ensure they meet accessibility standards. We strongly encourage instructors to use these vetted resources which include commonly-used tools like Sakai, Zoom and Warpwire. If you are using other tools, ask the vendor how the tool addresses accessibility to ensure that you can adapt your course activity to meet the needs of all students.

Accessibility in online environments
Students with disabilities who are attending a class remotely, whether a fully online class or a hybrid class, may have different accessibility needs than if they were attending a class entirely on campus.
Contact the Disability Management System office with questions. Their staff can help if you have questions about how to adapt your course to accommodate students with disabilities. You can also refer students to this office if they have questions about how their established accommodations translate to different course formats, including hybrid courses where some students may participate in class online.

- Review your course’s documents and make sure they are all in accessible file type and format.
- Plan for how you can use Zoom to create accessible class meetings and video recordings.
- For videos you are recording, make sure you use Zoom’s accessibility features, including closed captioning and audio transcript.
- When using other video materials, make sure the video has clear audio and close captioning.
- Be ready to work with the Duke Disability Management System for additional accommodations for videos used in your course, such as adding captions or audio descriptions.
