Best Practices for an Accessible Online Classroom 

Best Practices for an Accessible Online Classroom 

An accessible online classroom can be engaged with by all students across a wide spectrum of disabilities, ages, experiences, learning environments and other factors. The exact steps you may need to take will depend on the type of content you are creating. We have outlined general steps, and provided links to specific common platforms. These tips and best practices were developed as part of COVID-19 teaching continuity activities. Another resource for accessibility related information is the UMass Amherst Disability Services COVID-19 Response Website.

Planning the switch to online 

  • Review UMass materials on Universal Design and Accessibility:
  • Become familiar with the Universal Design for Learning (UDL) guidelines. These guidelines are broken out into three categories: Engagement, Representation, and Action & Expression. Incorporating UDL into your course will improve the experience for people with permanent disabilities, people learning English as a second language, people encountering temporary disabilities and, generally, all of your students who may be encountering uncertain situational environments at this time (e.g., cognitive overload, mental and emotional exhaustion, internet connectivity issues, etc.). 
  • If a student requests an accommodation, make your materials available as soon as possible to Disability Services. Accessible textbooks, videos, etc. can take several weeks to go through the accommodation process. These accommodations are essential for students with disabilities to succeed. 

Communicating with students 

  • Provide an accessibility statement in your syllabus. 
  • Provide clear and detailed instructions for any activity. This includes information about when things are due, what task(s) should be completed, and what tools are needed. If possible, include instructions for using a platform or tool, so that students are engaging with the content, and not stuck on a tool. 
  • Provide students with links to “how to materials” for the technology you will utilize during your class. Expect that not everyone in your class will be technology savvy.
  • Keep channels of communication open. Continue to offer office hours virtually and provide multiple ways for students to communicate. Check on students who have low attendance now that you’ve switched to a virtual environment. Encourage feedback on the current course format so you can address any issues students may be encountering with the format.  
  • Consider using asynchronous (pre-recorded) format rather than synchronous (live) format for teaching. Pre-recorded lectures give Disability Services the opportunity to incorporate accommodation requests, such as video captions and transcripts. Pre-recorded lectures are also great for anyone with a cognitive disability who may need to re-watch materials and for anyone currently facing situational obstacles, such as internet issues or limited devices per household.
  • Review Zoom accessibility best practices for holding synchronous sessions. 

Recommendations for all accessible materials

Accessible materials follow standard rules regardless of the tool used. 

  • Use the most up-to-date software. Download university licensed Microsoft Software for personal and university owned computers. See detailed videos on how to make Microsoft-specific documents accessible and general Microsoft Accessibility resources.
  • Use a tools’ built in accessibility checker. Most tools and platforms have default accessibility checkers that will help you identify problem areas in your documents. They are not perfect, and they should be used in conjunction with your own knowledge and experience. 
  • Whenever possible, house course readings in UMass library eReserves. This will help with both copyright and accessibility considerations. If you must scan a document, use Optical Character Recognition (OCR) to convert images to text.  If you have scanned a document and the file was saved as an image, it will not be accessible to students using many assistive technologies. You can use RoboBraille OCR to convert the image to a text-editable document. This process is not perfect, and the document may require editing.
  • Use University-approved products for your classes, including approved online course platforms (Moodle or Blackboard) and document sharing tools (Apps at UMass or OneDrive ). If you would like to use an external product, please contact the Associate Chancellor of Compliance for accessibility vetting. 
  • Work with instructional designers to identify authentic assessments and exam techniques to help ensure accessibility and maintain instructional integrity. 

Use high-contrast colors

  • High contrasts in colors makes them easy to see and read for everyone. Black text on a white background is the most common. If you plan on adding colors through changing backgrounds or using highlighter colors, make sure they do not obscure or make the text hard to read, such as yellow text on a green highlight. If you are using colors, make sure they are not the only way to convey information and check for color contrast.

Use true lists

  • Use the application's List features to create a true list. This will allow students using assistive technology to navigate through the list quickly and efficiently. Lists can be customized with formatting, bullets, and numbering conventions. 

Use Alternative text to describe images

Use proper formatting and captioning for tables

  • Tables are often used for displaying complex information in easy-to-see ways. To make sure students using assistive technology can engage with the content, make sure you follow the proper guidelines for the platform you are using to create and format a table. Tables with headers or fixed columns should use the Header feature. Use the Captions and summary features to provide an overview to the table. This is a chance to highlight significant information that might be lost to those who cannot see the table clearly. See Microsoft Word tutorial on creating accessible tables. 

Accessible Documents

In addition to all of the general recommendations above: 

Use headings consistently

  • Using headings in your document will allow students to orient themselves and navigate through the document. This is especially important for students using a screen reader or assistive technology for navigation. This is different from using formatting such as increasing the size or adding bold for emphasis. See Microsoft Word tutorial on creating headings.

Accessible presentations

Creating an accessible presentation follows much of the same guidelines for creating an accessible document. Clear, consistent formatting and organization of your slides will make them accessible to everyone. Use images when necessary to add context or highlight topics, but avoid too much unnecessary decoration. If you are using slides heavily, considering providing students with access to the slides before the lecture. If students need to use assistive technology, they can follow along. It will also help students with cognitive issues focus and engage on your content. 

Use clear formatting and organization

  • While you are creating your slides, remember less is often more. Aim for clear, concise slides with a standard layout to present information to students. Consistent formatting and structure will make it easier for students who have cognitive disabilities to absorb and understand information. Avoid unnecessary text and images, and large blocks of text. 

Use large and readable fonts and colors

  • For presentations, using a simple sans-serif font set to 24pt or large will ensure your slide is easy to read for you students, including those in the back of the room and those students who are low-vision. If you are using colors, make sure you use high-contrast colors so differences can be seen from afar. When using color, make sure it is not the only source of information, so that students who cannot see color or highlights still understand the importance of the content. 

Set the reading order of slide contents

  • Setting the reading order will allow students to access the content in a logic order that you specify. This way, they will be able to keep up with your description of the slides and information. 

Use titles to orient students

  • Applying a meaningful and unique title to each slide will allow a student to quickly navigate through your content and find relevant information. 

Accessible audio and video

Accessible media requires several components. Depending on the media that is produced, and the platform that is used, the process for creating accessible media will be different. 

Create a transcript for audio-only content

  • A transcript provides a copy of the words and sounds from content like a podcast or an audio lecture. If you are using a script to pre-record lectures, it will be easy to produce a transcript. Transcripts should always be accurate, identify changes of speakers, and any non-verbal sounds that are important to the content. Some players and services allow for synchronous and interactive transcripts, but timestamps are not required for audio-only transcripts to be accessible. 

Add captions to video content

  • Captions are text representations of audio happening in video media. Captions are different from subtitles; captions are in the same language as the original media, subtitles are a translation of the original media’s language into another language. They can take the form of Open Captions (OC) which are always on, and Closed Captions (CC) which can be turned on and off by a user. Unlike transcripts, captions provide text on a screen synchronously with the audio. Captions should follow ADA guidelines to be 99% accurate and be available as soon as the video is available to any students. If you have the ability, captions should be added to the bottom of the screen, and be high-contrast or on a background to make them visible. Caption locations can be adjusted to make sure they do not cover important content on the screen. Note: A transcript of dialogue provided for video content does NOT meet accessibility guidelines. Professional captioning can be very expensive. See options for Automatic Speech Recognition:

Add video descriptions

  • Video descriptions are an additional audio track that provide description of scenes and actions taking place. When narrating slide presentations, verbally describe all visual elements. This will reduce the need for audio descriptions for content you are showing to your students.
