Do record lectures if you need to. When information cannot be learned otherwise, include a lecture. Your university already some kind of tech to record lectures. DO NOT simply record in PowerPoint as the audio quality is low. While many people recommend lectures of only 5 minutes, I find that my students really do listen to longer lectures. Still, remember that your students will be frequently interrupted in their listening, so a good rule is 1 concept per lecture. So, rather than a lecture on ALL of, say, gender inequality in your Intro to Soc course, deliver 5 minutes on pay inequity (or 15 minutes or 20 minutes, if that’s what you need) and then a separate lecture on #MeToo and yet another on domestic violence. Closed caption them using the video recording software your university provides. Note that YouTube also generates closed captions [edited to add: they are not ADA compliant, though]. If you don’t have to include images, skip the video recording and do a podcast instead.
