Developing Accessible Audiovisual Content for Digital Learning

March 29, 2024

In recent years, digital learning and corporate education have experienced significant growth, with more organizations embracing technology to deliver training and educational content. As reliance on digital platforms and solutions continues to increase, it’s important to ensure that the audiovisual content created for these purposes is accessible to all learners, regardless of their abilities or disabilities. Accessibility in digital education goes beyond being a mere checkbox on a list of requirements; it’s a principle that ensures equal opportunities for learning and growth. By prioritizing accessibility in the creation of audiovisual content, we foster inclusive learning environments that cater to the diverse needs of our audience. Accessibility should be a top priority in creating audiovisual content for digital education, as it ensures equal access to learning opportunities, promotes inclusivity, and benefits both learners and organizations alike. This write-up aims to explore the importance of accessibility in digital education, highlight common challenges, and provide best practices for creating inclusive audiovisual content. 

Accessibility in digital education refers to the design and development of audiovisual content that can be effectively used by individuals with a wide range of abilities and disabilities. This includes learners with visual, auditory, motor, and cognitive impairments, as well as those with temporary or situational disabilities. According to the World Health Organization, over 1 billion people worldwide live with some form of disability. In the United States alone, the Centers for Disease Control and Prevention (CDC) reports that 61 million adults, or 26% of the adult population, have a disability. These statistics highlight the significant portion of the population that relies on accessible content to engage with digital learning materials. Moreover, creating accessible audiovisual content is not just a matter of good practice; it is also a legal requirement. In the United States, the Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act mandate that digital content be accessible to individuals with disabilities. Failure to comply with these regulations can even result in legal consequences and damage to an organization's reputation.

Beyond legal obligations, ensuring accessibility in digital education is an ethical and moral imperative. Every learner deserves equal access to education, regardless of their abilities or disabilities. By creating inclusive audiovisual content, we break down barriers to learning and provide opportunities for all individuals to acquire knowledge and skills.

Despite the growing awareness of the importance of accessibility, many audiovisual materials in digital education still present significant challenges for learners with disabilities. Some of the most common accessibility barriers include: 

  1. Lack of closed captioning or subtitles: Deaf or hard-of-hearing individuals rely on closed captions or subtitles to understand the audio content of videos. Without these textual representations, they may miss out on crucial information and struggle to fully engage with the learning material.
  2. Absence of audio descriptions: Visually impaired learners benefit from audio descriptions that provide verbal explanations of visual elements, such as on-screen text, charts, or key actions. The absence of audio descriptions can make it difficult for these learners to comprehend the full context of the audiovisual content. 
  3. Poor color contrast or small text size: Learners with low vision or color blindness may face challenges when the audiovisual content features poor color contrast or small text size. This can make it difficult to read on-screen text or distinguish between visual elements, hindering their ability to effectively consume the content.
  4. Complexity of navigation: Learners with motor or cognitive disabilities may struggle with complex navigation systems or interfaces that require precise mouse movements or rapid response times. Inaccessible navigation can prevent these learners from accessing the full range of audiovisual content or completing interactive elements.
  5. Lack of keyboard accessibility: Some learners with motor disabilities rely on keyboard navigation instead of a mouse. If the audiovisual content or platform does not support keyboard accessibility, these learners may be unable to interact with the material effectively. 

Recognizing these common accessibility challenges is the first step in creating inclusive audiovisual content. By understanding the barriers faced by learners with disabilities, creators can take proactive measures to address these issues and ensure that their materials are accessible to all.

To overcome the accessibility challenges discussed above, there are a number of key strategies creators can follow when developing audiovisual materials for digital education. Some may include: 

  1. Incorporating closed captions and transcripts: Provide accurate closed captions or subtitles for all video content, ensuring that the text is synchronized with the audio. Additionally, offer full transcripts of the audio content to support learners who prefer reading or need to review the material at their own pace.
  2. Providing audio descriptions: Include audio descriptions that verbally describe essential visual elements, such as on-screen text, charts, graphs, or key actions. These descriptions should be concise and well-timed to avoid interfering with the main audio content.
  3. Ensuring sufficient color contrast and readable text: Use color combinations that provide adequate contrast between text and background, following the Web Content Accessibility Guidelines (WCAG) standards. Ensure that the text size is large enough to be easily readable, and provide options for users to adjust the text size if needed.
  4. Designing user-friendly, keyboard-navigable interfaces: Create intuitive and user-friendly navigation systems that can be operated using a keyboard alone. Ensure that all interactive elements, such as buttons, forms, and media controls, are accessible via keyboard commands and provide clear focus indicators.
  5. Conducting accessibility testing with diverse users: Engage users with different abilities and disabilities in the testing process to gather feedback on the accessibility of the audiovisual content. This can help identify issues that may have been overlooked and ensure that the material is usable by a wide range of learners.
  6. Incorporating a high volume of on-screen graphics: To enhance the learning experience for all users, especially those with auditory processing difficulties or hearing impairments, it is crucial to include a rich array of on-screen graphics that complement the spoken content. These visual aids can include:

  • Diagrams and illustrations that break down complex concepts
  • Flowcharts and mind maps that visualize processes or relationships
  • Infographics that present data or statistics in an easily digestible format
  • Animations or video clips that demonstrate practical applications or real-world examples

By providing a high volume of on-screen graphics, content creators can offer multiple means of representation, allowing learners to engage with the material through both auditory and visual channels. This multi-sensory approach reinforces key ideas, aids in information retention, and accommodates diverse learning preferences. When incorporating on-screen graphics, it is essential to ensure that they are also accessible. This means:

  • Providing alternative text (alt text) for images and graphics, describing their content and purpose for visually impaired learners who use screen readers
  • Ensuring that the graphics are clear, high-contrast, and easily distinguishable from the background
  • Using color palettes that are accessible to individuals with color vision deficiencies
  • Avoiding the use of graphics that flash or flicker, as they may trigger seizures in some individuals with photosensitive epilepsy

Prioritizing accessibility in audiovisual content creation offers numerous benefits for both learners and organizations. Some of the key advantages include: 

  1. Inclusive learning environments that cater to all students: By ensuring that audiovisual materials are accessible, organizations create learning environments that welcome and support all students, regardless of their abilities. This inclusivity fosters a sense of belonging and encourages active participation from all learners. 
  2. Improved user engagement and retention: Accessible audiovisual content enables learners to fully engage with the material, as they can access the information through multiple sensory channels. This enhanced engagement leads to better understanding, increased knowledge retention, and higher completion rates for digital learning programs.
  3. Enhanced brand reputation and social responsibility: Organizations that prioritize accessibility demonstrate their commitment to social responsibility and equality. By creating inclusive learning experiences, they showcase their values and enhance their brand reputation, attracting positive attention from stakeholders, customers, and the wider community.
  4. Compliance with legal requirements and avoidance of potential lawsuits: As mentioned earlier, ensuring accessibility is not just a moral obligation but also a legal requirement in many jurisdictions. By adhering to accessibility standards and guidelines, organizations mitigate the risk of costly lawsuits and legal challenges related to discrimination against individuals with disabilities.
  5. Broader reach and increased market share: Accessible audiovisual content allows organizations to reach a wider audience, including individuals with disabilities who may have previously been excluded from digital learning opportunities. By catering to this significant and often underserved market, organizations can expand their customer base and increase their market share.

As we move forward in this new era of education, it is imperative that content creators, instructional designers, and organizations alike recognize the importance of accessibility and take proactive steps to implement inclusive design principles in their audiovisual materials. By doing so, we can break down barriers to learning, provide equal opportunities for all students, and create a more equitable and inclusive educational landscape.

We call upon all stakeholders in the digital education sector to prioritize accessibility in their content creation processes, to seek out and implement best practices, and to continuously strive for improvement in the development of inclusive audiovisual materials. Together, we can build a future where every learner, regardless of their abilities, has access to high-quality, engaging, and transformative educational experiences.
