The term podcast refers to a series of audio recordings, available online, to which users can subscribe, download, and consume via a computer or mobile audio device. Podcasts can be audio only or can contain blended media - the coordination of images or video with an audio file. One key attribute is the ability to subscribe to the podcast, allowing the user to automatically download new episodes as they become available.
Podcasts can be used to capture and distribute an audio recording of a lecture, or to deliver supplemental content to students such as a digest of important points covered during an online class session or to give verbal feedback to students on an assignment.

|Ability to give audio feedback to students on assignments gives them a more personal response from an instructor.
|If a student has a legitimate reason for missing a synchronous activity (illness, etc.) it can be recorded for them. || |

- Give students clear instructions on how to access podcasted materials.
- If using a podcast to distribute mandatory course content, make students aware that they will be required to download and listen to each podcast.
- Keep podcasts under 20 minutes. A student’s attention span begins to decrease significantly after 15-20
minutes of material have been presented; keeping your podcast within or
less than 20 minutes will keep the student more focused on the full
- Limit the number of new concepts covered in each podcast. Limiting your content to 3-5 “chunks” of new material will give
students a manageable, but not superfluous, amount of information to
store in working memory.
- Feel free to relax and take a conversational approach when recording a podcast.
