The use of audio content can range from classroom lectures to review sessions, and can usually be created in the form of podcasts or audio recordings. You can make them available either as a single person presenting the material orally or as a recorded conversation or interview between one or more people. Podcasts can be used to deliver content as short microlectures, full seminars, lecture summaries, review sessions, supplemental course material, answers to FAQs, or assignment feedback. However, short recordings of 2-5mins is optimal, and going 15mins long may not be suitable. Audio content can also be student-created recordings based on assignments such as reviews, projects and/or presentations.
Pedagogical advantages of audio content
- Podcasts are best suited for creating audio archives of classroom lectures, as it allows accessing these anytime, anywhere particularly during commuting to and from campuses. Students can download these audio files and listen to them independently at their convenience (self-paced, mobile learning)
- Podcasts can be ideal for delivering key concepts and themes condensed down to one-minute to three-minute segments.
- Easy to explain complex concepts verbally than as written text.
- Supplementary materials that include pre-recorded lectures can serve as materials that can be accessed prior to class time or as reviews of homework problems.
- Provide access to subject matter experts or interviews with guest speakers.
- In-class discussions can be recorded for extending discussions further making students part of the content creation process.
