Introduction
Media has the power to transform your classroom by supplementing course materials, sparking discussions, and explaining complex concepts. Videos and audio can make learning more interactive and dynamic while giving you reusable content for future semesters. This guide will help you create videos and audio that work for everyone in your classroom. You’ll learn practical strategies to make your media more inclusive and discover why accessible design benefits all your students, not just those with specific needs.
Principles for Effective Media
Richard Mayer’s multimedia learning theory includes 12 principles that guide effective instructional design. The four principles that are particularly important for creating accessible and effective course media: coherence, signaling, redundancy, and segmenting. These principles will help you create videos and audio that support student learning while reducing cognitive overload.
Learning Outcome
By the end of this module, you will be able to:
- Create inclusive video and audio content that enhances the learning experience for all students.
Accessibility Essentials
“Accessibility features are also used by people without disabilities in a variety of situations.”
(Web Accessibility Initiative, n.d.)
Understanding Educational Media
Educational media includes any videos or audio you use for teaching. This could be a lecture recording, an instructional video, or a podcast episode. When designed thoughtfully, these resources can supplement your course materials, promote discussion, provide real-life examples, and free up valuable class time.
The key is keeping things simple and focused. Students learn best when they can control their experience: pausing to take notes, rewinding difficult sections, or reviewing content multiple times. Videos are particularly effective for learning medical procedures, math equations, and counselling techniques because students can rewatch content as many times as needed to fully grasp the concepts being taught (Noetel et al., 2021).
What Makes Media Accessible?
Accessible media is designed so everyone can use it, regardless of their abilities or circumstances. This includes:
- Captions for videos
- Transcripts for audio content
- Clear audio quality
- Simple, direct language
- Good color contrast in visual elements
The goal is ensuring equal access to your educational content. When you design with accessibility in mind from the start, you create better experiences for everyone. Captions and transcripts are recognized as Universal Design for Learning (UDL) and inclusive design because you are composing in multiple media, speech and text, and designing for adaptability and inclusivity (UDL, 2022; The Inclusive Design Guide, n.d.).
Listen to Brenna discuss her first foray into podcasting and how her audio lectures inadvertently made her class more inclusive and accessible (length 1:50).
Please know that you do not have to make all your own videos and audio files! Listen to Jon discuss when to create your own course media and when to use someone else’s!

Why Accessibility?
“Inclusive design acknowledges the essential nature of accessibility and proactively seeks to provide user-friendly experiences for people with and without disabilities.”
(Phillips & Colton, 2021)
Think about curb cuts on sidewalks. Originally designed for wheelchair users, they now help parents with strollers, delivery workers, and anyone with mobility challenges. Accessible design benefits everyone, not just people with disabilities.
The same principle applies to course media. Captions help students who are deaf or hard of hearing, but they also help anyone studying in a noisy environment or whose first language isn’t English. Transcripts allow students to search for specific information or study without sound.
Listen to Jamie’s story about her struggles in the classroom and her first experience with captions (length 5:42)!

(Phillips & Colton, 2021)
Listen to Brenna Clarke Gray discuss thinking a little differently about how accessibility and accommodation function (length 5:24).

When students cannot access your content, they miss out on learning opportunities. By designing inclusively, you create a more equitable classroom where all students can succeed.
How Accessible Media Enhances Learning
Accessible videos and audio improve the learning experience in several ways:
Flexible learning: Students can engage with content at their own pace, reviewing difficult concepts as needed. This reduces cognitive load and helps with comprehension (Fiorella, 2021).
Multiple formats: Providing the same information through different channels (visual, auditory, text) helps students with different learning preferences and needs.
Better engagement: When students feel included and can access all course materials, they’re more likely to participate actively in learning. Students can struggle emotionally and cognitively when they don’t feel a sense of belonging in the classroom (Bowen, 2021).
Increased comprehension: Captions and transcripts can improve understanding for all students, not just those who need them for accessibility reasons.
Study support: Transcripts can be downloaded, searched, and reviewed offline, giving students more study options.

Implementation Guide
“Part of inclusive teaching is acknowledging the uniqueness of students and teaching using a variety of ways such that it reaches a diverse audience.”
(SNOW, 2018)
Getting Started
Focus on good audio quality first—it’s more important than perfect video. Students need to hear you clearly to benefit from your content. Don’t worry about making everything perfect; authentic, relatable content often works better than overly polished productions.
Adding Captions and Transcripts
For Kaltura users: The system generates automatic captions, but you’ll need to edit them for accuracy. Machine-generated captions often contain errors due to background noise, accents, or technical terms.
Learn how to edit and download captions in Kaltura videos.
You will find comprehensive written instructions for editing captions in Kaltura at Accessibility and Enrichment: Editing Captions.
For YouTube: Use the platform’s automatic captioning feature, then review and edit for accuracy. YouTube provides comprehensive instructions for:
For other platforms: Most screen recording software offers captioning options, or you can add captions during the editing process. If you are on a MAC you may choose to use QuickTime and if you are on a Windows computer you can check out iSpring Free Cam. You could also use Loom which works on any device or you could use paid softwares such as Snagit or Camtasia.
Audio Considerations
If you’re creating audio-only content, always provide a transcript. Consider recording lectures with a simple external microphone connected to your phone, this creates reusable content students can access anytime. For audio editing we recommend Audacity, Audacity is a free, open source software that works on Windows, macOS and many other operating systems.
Best Practices
“Turns out good content is still effective — we just have to provide it!”
(Knot, 2010)
- Test your content with captions on to ensure accuracy
- Use clear, simple language in both spoken content and captions
- Include diverse representation in your videos when possible
- Keep segments short to maintain engagement
- Provide context when reusing content across semesters
Moving Forward
Start small by adding captions to one video or creating a transcript for one audio file. As you become more comfortable with these tools, you can apply these practices to more of your content.
Remember that accessibility isn’t just about compliance—it’s about creating inclusive learning environments where all students can thrive. When you design with everyone in mind, you create better educational experiences for your entire class.
Conclusion
Creating accessible course media is an ongoing practice that gets easier with time. By focusing on clear audio, accurate captions, and thoughtful design principles, you’re building a classroom where every student has the opportunity to succeed. Start with small changes, learn from your students’ experiences, and remember that each step toward accessibility makes your teaching more effective and inclusive for everyone.
Connection to Competencies
The Making Course Videos and Audio Accessible guide supports the B.C. Post-Secondary Digital Literacy Framework (opens in a new tab) by developing educators’ capacity to create and present accessible, inclusive course materials that prioritize diverse learner needs. This guide most directly aligns with Ethical and Legal Considerations as it helps instructors understand their responsibilities to provide equitable access to educational content and comply with accessibility standards. It also enhances Creation and Curation by building practical skills in formatting and structuring course materials for accessibility. Lastly, it strengthens Digital Scholarship as participants learn how accessibility features support learning for all students and explore best practices for inclusive digital content design. Together, these competencies help instructors to produce course media that is accessible from the beginning, thoughtfully structured, and designed to serve the all learners in their courses.
