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.
