Audio in Online Learning banner.

Audio is a term we all understand on some level. Commonly we think of audio as the transmission, reception, or reproduction of sound. Audible sound is what we hear. So, when we consider audio as an element of course design we are thinking about how sound can be used to communicate or support learning in an online course environment. Integrating audio in course delivery can be quite powerful if done well.

Perhaps the most common method of using sound in an asynchronous online course is via narrated lecture. The narrated lecture is typically a voice over a slide presentation or screencast. It can be an essential tool of instruction if designed effectively.

Another way the voice of an instructor can be incorporated into a course is via audio feedback on student assignments. These are short audio recordings that have been found to help build a sense of instructor presence in an online course.

Highly focused use of audio is also utilized in subjects where audio is, in essence, the topic at hand. Here we are considering language, music, and media arts courses as examples.

Other valued voices are often brought into the online learning experience via guest interviews in either audio or video format. Not to be left out, the voices of students are increasingly present in online course via tools such as VoiceThread and university provided video portals such as Kaltura Media Space. And with tools such as Zoom recording audio interviews and voice overs is easier than ever. With the availability of media platforms such as YouTube, Vimeo, Amazon Prime, Audible, and Apple Music and Podcasts the ability to bring external audio resources into the online experience seems almost limitless.

Audio is also used as a supporting resource for text-based content in online courses. In this case screen readers may typically provide the audio support. When using audio as a primary learning resource it is necessary to provide text-based transcripts as accessibility options. A fuller description of making audio accessible can be found at the W3C website.

The examples listed above are common ways we integrate audio elements into online learning. Are there other perhaps different ways we might consider? In the next few paragraphs we will explore a few ideas of how we might use audio in specialized ways in course design.

Specialized Audio Use

Orientation & Review Audio

Audio is a great tool to use when smaller segments of media should be used to orient students to a part of an online course. Think about short, more ephemeral, voice messages that can be easily produced and updated from term to term as the course changes. These audio segments need not be highly produced but should be of good quality. This type of audio segment reconnects students with the instructor via voice.

Listen to the orientation audio sample below that was used in an online course: RE 270 – Outdoor Recreation Resources, Behavior and Values | Module III Orientation by Dr. Craig Rademacher; Northern Michigan University c. 2012. (00:02:56).  [download orientation audio transcript  from Temi.com]

Similar short segments of audio may be used to review sections of content. The review audio may be produced by instructors or students. These audio reviews may be used in preparation for an exam, major project, or collaborations within the course. The goal of such reviews may vary but certainly one goal would be to re-focus the listener to the task at hand while providing timely tips or learning objectives.

One of the things you may have noticed about the audio clip above is the integration of music to the orientation message. Purposeful music selections can support the emotional feel of a course or module being introduced. Music can also serve as an audio cue, or audio branding, for a course. So, selecting audio stingers, or music introductions, can highlight that a particular message or topic is coming or reinforce an emotional tone if carefully planned.

The primary benefit of using audio for orientation and review is that audio is less production intensive making it a quick way to provide feedback. Audio is also fairly easy to edit with a free cross-platform audio tool such as Audacity.

Narrative

The oral traditions of learning go back centuries. Prior to print, learning was interwoven in spoken traditions, legends, and cultural stories. Today story remains a potent vehicle for learning. As you might imagine audio is a great vehicle for story.

An example of this is an Oregon State University political science course titled Governing after the Zombie Apocalypse which was designed and taught by Dr. Rorie Solberg. The story that underpins this course is that a natural disaster has caused the breakdown of the U.S. government. In response citizens must create a new government including a bill of rights and constitution. Students become the citizens creating that new government taking into account marginal populations such as the surviving zombies which are called “blues”due to their virus-caused color.

Audio is used creatively in the course by periodically inserting radio broadcasts about odd happenings around the country. Although not the heart of the effort of the course, these audio presentations, really imagined radio newscasts, provide situational tenor and decision points as students go about creating a new government. Listen to a segment of a mock radio broadcast below.

This segment highlights how audio can be used to shape and carry a narrative through an online course. You might imagine how different narrative audio presentations may support history, literature, or science courses.

Soundscapes & Nature Sounds

Experiencing authentic places or environments is believed to be a valuable form of learning. This idea is a driving force behind field-based learning and experiential learning. Audio soundscapes provide access to authentic acoustic environments that can support online learning about the context of an environment. The environment may be urban, rural, or perhaps in a wilderness-like setting. Soundscapes may also be used to create sense of cognitive and emotional world building that can be used in instruction. Soundscapes typically feature a molar perspective of the acoustic environment.

Listen to an example of such a soundscape titled Elk Rut and Rain Shower — Rocky Mountain National Park in Colorado by Gayi immersions (00:28:03) at SoundCloud. (link will open in a new tab)

Other, more specific sounds of nature are potentially positive resources for online instruction. Below is a sound sample of the call of a common raven. Listen to the raven’s call.

Audio recorded in the Beaver Basin Wilderness at Pictured Rocks National Lakeshore in Michigan in 2010 | Craig Rademacher. (00:00:26)

Now imagine how this simple recording may be utilized in a course. It might be used to help identify ravens from crows in an ornithology course. Perhaps this audio clip could be used to help communicate a sense of isolation for listeners studying wilderness values. Or, perhaps it could be used to introduce the poem by Edgar Allen Poe titled The Raven. In each case the audio would be used intentionally to deepen the context or experience of the learner.

Fidelity Matters

Sound quality is an important factor when selecting and using audio in an online course. Audio files need to be of sufficient quality to clearly indicate what you are expecting students to hear. Poor audio, or a confusing sound recording, is experienced as distracting and student will likely tune out. Recording and editing audio does require some knowledge and practice. And there are many places where you can learn to produce audio. LinkedIn Learning offers courses in audio production, podcasting, and even how to select a microphone. So, if you are interested give it a try.

If you are not inclined to produce your own audio content there are resources available where you can find high quality audio for use in courses. Some of these resources are royalty free. Others may require licensing of audio for use.

Final Thoughts

We have reviewed how audio is commonly used in online courses and how we might think about new ways of integrating audio. As you explore the links to resources below start to think about your next course design. How can you augment the text and video you normally use with audio? How might you leverage voice, narrative, or soundscapes to connect online students to the context, authenticity, and humanity of learning? You might want to experiment with audio at first. Start small. If it works, then you will have truly found a sound idea for online course design.

Select Audio Resources

Royalty free online resources:

Podcast Resources
There are several ways to find audio podcasts to review for inclusion in a course. Apple Podcasts is a dominant resource in this area. Apple streams over 750,000 podcast shows with over 20 million episodes. Google Play Music is another good resource. Podcast feeds can also be found simply by browsing for podcasts online.

Audiobooks
Audiobooks are found in many online book seller sites such as Amazon (Audible.com). Additionally some more specific sites such as audiobooks.com also provide resources.

Welcome to the Webcam and Video Tips guide by Oregon State University Ecampus
This brief series of tips is meant to be a beginner’s overview for DIY home recording on webcam, with some additional options suggested if you want to take your video production even further.
Since this document may not cover every issue you encounter while acclimating to DIY video recording, we recommend contacting your school tech person for additional troubleshooting.

WHERE TO START

  • Internet Connection
    • Wired connection via ethernet cable is best
    • If wired connection is not possible, having a clear line of sight to wifi router will give the best wireless connection
    • Disconnect any wifi devices that are not in use or needed.
  • Computer Check
    • Determine if your computer meets minimum system requirements for streaming software
    • Close all non-essential programs to free up more computer resources
    • Disconnect any external monitors if you are on a laptop and it is running slowly
  • Testing Your Tech
    • Does your computer have a built in webcam or do you have a 3rd party webcam?
    • Identify where your microphone is and talk towards it
    • Test the webcam and audio settings BEFORE your first recording. 
    • Practice practice practice
      • The last recording will be better than the first
  • Making sure your voice is clear and easy to understand
    • Having a microphone helps with this
    • Smart phone earbuds have a built-in microphone that can help you with voice clarity
    • Airpods would also work when recording to an iPhone

PRESENCE AND ENVIRONMENT

  • Be aware of your environment.
    • Limit any background noise as much as possible.
    • Clean up your space and be aware of what is in the background of the video.
    • Rooms with carpets and drapes are best for audio.
    • Turn off lights and close windows that are behind you when you are recording.
    • If possible, turn on a light behind the camera.
    • Keep experimenting with lighting until you have a set up that works for you.

  • Try not to bump the desk, computer, camera, or microphone while recording.
    • Typing should also be avoided.
  • Do a test lecture and watch it.
    • See what works and what doesn’t.
    • If possible, get feedback from others
  • Practice
    • The more you practice, the more natural it will feel.
    • Run through what you want to say before you start recording.
  • Relax and be natural! Hopefully you are sharing knowledge that you are passionate about and we want that to show. (Remember that we are always our own worst critic, and your teaching team will be there to help you with constructive feedback on how to help students best enjoy and learn from these videos.)
  • Have notes in front of you while you’re recording. 
    • It is easy to get distracted or off topic, especially when you are uncomfortable.
    • Having notes in front of you while you record can help you stay on track.
    • These notes can be as vague or as detailed as you want, but avoid reading off of them directly and not looking at the camera.

DIGITAL NOTATION

GOING FURTHER WITH VIDEO PRODUCTION

  • For DIY video production, there are many ways to go about this!
    • The lowest barrier to recording on your own would be to use a smart phone attached to a tripod or other mount.
    • If you have access to a camcorder or DSLR, get out there and use it!
  • For smart phone video
    • Avoid handheld and invest in a tripod or smart phone / camera mount
    • If you have a decent internet connection for uploads, consider recording 1080p at 30fps
    • Use an external microphone whenever possible

ACCESSORIES TO CONSIDER IF RECORDING WITH A PHONE

Apps:

  • Filmic Pro – $14.99
    • Allows manual control of exposure and white balance, audio monitoring, and other useful features.

Audio:

  • Lavalier microphone – $18.99 
    • Highly recommended. Audio recorded from your phone’s microphone can be difficult to hear if you aren’t standing near the phone or if the location is noisy. 
  • Double lavalier microphone – $25.99
    • For when you have two people on camera. Both mic cable feed into the same phone, removing need to sync two audio sources. 
  • Audio cable extension – 10 ft. $9.95 or 20 ft. $15.95
    • For when you need to stand farther away from the camera.

Stabilization:

  • Selfie stick w/built-in tripod and Bluetooth remote – $23.99 (heavy duty, 51″ extended), $14.99 (27.6″ extended)
    • Terrific for self-recording in the field.
  • Combination hand grip/small tripod/tripod adapter – $8.89
    • Can be used as a hand grip for filming on-the-go or as a desktop tripod. Phone mount can be removed from the hand grip/tripod legs section, allowing you to mount your phone on most standard tripods.
  • Gimbal stabilizer – $94.99
    • Pricey, but will greatly increase the quality of your footage if you’re filming something that requires camera movement, such as a walk-and-talk interview or a field trip video.
  • Creative ways to mount a smart phone with household items:

 

ADD-ONS / TIPS AND TRICKS

  • If you would like to have access to a teleprompter as you record video, consider one of the following:
  • Here are some sound improvements to consider to reduce echo in your recordings.
    • Add blankets or blinds on walls to reduce echo.
    • Record in the smallest room possible.
    • Avoid rooms with hardwood floors.

Lighting for video

  • Turn a window or glass door into a soft “Key Light” by hanging a cheap, frosted shower curtain over the window.

First, let’s start by considering the characteristics of effective feedback in general. What comes to mind?

sound waves

Perhaps you hear in your head (in the authentically authoritative voice of a past professor) the words timely, frequent, regular, balanced, specific. Perhaps you recall the feedback sandwich–corrective feedback sandwiched between positive feedback. Perhaps you consider rubrics or ample formative feedback to be critical components of effective feedback. You wouldn’t be wrong.

As educators, we understand the main characteristics of effective feedback. But despite this fact, students are often disappointed by the feedback they receive and faculty find the feedback process time consuming, often wondering if the time commitment is worth it. As an instructional designer, I hear from faculty who struggle to get students to pay attention to feedback and make appropriate changes based on feedback. I hear from faculty who struggle to find the time to provide quality feedback, especially in large classes. The struggle is real. I know this because I hear about it all the time.

I’m glad I hear about these concerns. I always want faculty to share their thoughts about what’s working and what’s not working in their classes. About a year or two ago, I also started hearing rave reviews from faculty who decided to try audio feedback in their online courses. They loved it and reported that their students loved it. Naturally, I wanted to know if these reports were outliers or if there’s evidence supporting audio feedback as an effective pedagogical practice.

I started by looking for research on how audio feedback influences student performance, but what I found was research on how students and faculty perceive and experience audio feedback.

What I learned was that, overall, students tend to prefer audio feedback. Faculty perceptions, however, are mixed, especially in terms of the potential for audio feedback to save them time.

While the research was limited and the studies often had contradictory results, there was one consistent takeaway from multiple studies: audio feedback supports social presence, student-faculty connections, and engagement.

While research supports the value of social presence online, audio feedback is not always considered for this purpose. Yet, audio feedback is an excellent opportunity to focus on teaching presence by connecting one-to-one with students.

If you haven’t tried audio feedback in your classes, and you want to, here are some tips to get you started:

  1. Use the Canvas audio tool in Speedgrader. See the “add media comment” section of the Canvas guide to leaving feedback comments. Since this tool is integrated with Canvas, you won’t have to worry about upload and download times for you or your students.
  2. Start slow. You don’t have to jump into the deep end and provide audio comments on all of your students’ assignments. Choose one or two to get started.
  3. Ask your students what they think. Any time you try something new, it’s a good idea to hear from your students. Creating a short survey in your course to solicit student feedback is an excellent way to get informal feedback.
  4. Be flexible. If you have a student with a hearing impairment or another barrier that makes audio feedback a less than optimal option for them, be prepared to provide them with written feedback or another alternative.

Are you ready to try something new? Have you tried using audio feedback in your course? Tell us how it went!

Providing feedback to students is a critical component in any course and perhaps even more important in an online course where the instructor and students are not in the same physical space. Although written feedback is the primary method used when providing feedback to students, some instructors are turning to the use of audio feedback and finding that it is both easy to do and effective. Research has shown that audio feedback can allow for more nuanced messages to the student. It has also been shown to involve the student more deeply in a class and make them feel that the instructor really cares. One study even found an association between the use of audio feedback and better retention of course content.

There are several online tools that allow you to create and share audio clips easily. One that I’ve used recently is Chirbit. You only need a microphone and you can record clips up to five minutes in length. There is no limit to the number of audio posts that you can share on Chirbit. Once you create an audio clip you can mark it as private and then share the link that is provided with your student. Chirbit has a number of other capabilities for sharing clips that you can explore even further, including the ability to attach transcripts or QR codes directly to audio clips.

Consider choosing one assignment next term that you could experiment with by providing audio feedback to students. Some instructors have reported that giving audio feedback is actually more efficient for them than giving written feedback. It is definitely another way to extend your presence in the online classroom.

Some instructors are surprised when they first hear that they should begin preparing for a recorded lecture by writing a script. Some instructors believe that writing a script will take a lot of time, and that using a script will make the finished recording sound like they are reading, and that they should approach their online lectures the same way they do the on-campus ones – without a script.

Preparing a script for an online lecture is an essential step, however, that actually helps to save time and create a higher quality finished lecture.

So why script your lectures?

  1. To Save Time
      You will be surprised how much time and frustration you will save yourself when you are recording lectures. You won’t have as many flubs-ups or wonder if you actually covered everything you were planning on covering only to discover you didn’t. If you do mess up, it’s easier to re-record.
  2. To Keep Online Lectures at an Ideal Length and Quality
      A script will also help you keep track of time. We recommend that online lecture be no longer than 20 minutes (and shorter is better!). This time limit is very hard to achieve when you don’t know how long you plan on talking, or if you go off on a tangent.
      One trick you can do so you don’t sound like you are reading a script is writing your script in a less formal manner. How will you know if it’s less formal? Read it out loud after you write it! If you find yourself getting stuck on words or just find it hard to read, try restating the sentence as though you are just talking with a friend or a student in your office. Also, practice reading your script two or three times before you record; this will make the whole recording process go more smoothly.
  3. To Make Lectures Accessible
      An added bonus to scripting your lectures is that it would be transcribed for students with documented disabilities, or for those for whom English is a second language.

On-campus and online courses meet the same learning outcomes, but the online learning environment is different from the face-to-face environment. Writing a script as the first step in creating your online lecture content is a great way to help you create content that will be effective for online students.

A great example of a lecture that was recorded with a script was done by Julia Goodwin for her HST 104 course World History I: Ancient Civilizations, here is her lecture for week 8

The use of audio recording tools in online classrooms is a great way to incorporate student voice in an otherwise silent environment. Providing students with various methods to give, receive and store information using multiple learning modalities greatly enhances learning.

Instructors can use simple audio recording tools to both deliver course content and assess learning. The recorded voice messages can serve as mini-lectures, clarifications to muddy topics, quick reminders and more. Your students can respond to your voice messages verbally by posting a comment to your recording.

Some ideas for student-generated content include general introductions, interviews, or even a Q&A session with student experts. Audio recording tools are great resources for the foreign language classroom and can be used to assess your students’ speaking skills in the target language.

Here I’ve included a 30 second example of a ‘boo’ (what Audioboo calls their recorded messages) with more information.
