Audio lectures are traditionally individual sessions where you only record audio talking about your course content.
When only recording audio, it is important to consider any visual concepts or examples you will be discussing. You will need to describe these visuals in detail so that students fully understand what they are hearing.
Group discussions consist of two or more people talking about your course content. The other subjects in the video can be subject-matter experts, or students.
These group discussions can be expressed through interviews, socratic dialogues, or panel style discussions.
For purposes of recording at home, we recommend limiting the number of participants to two. This will help avoid crowding people into the video frame, and provide a clean and clear image for the students.
