For open-ended questions, you can enable the option for students to record an audio response, rather than or in addition to a written response.
While editing your video lessons, each open-ended question will have a toggle switch that can be used to allow students to submit a recorded audio response. To activate this feature for a question, toggle the “Allow answer with audio” option to “On.”
Students’ audio responses will appear alongside any additional written response when grading assignments.
