You don’t need a live video feed to teach online.
Live video might actually hinder students’ learning by giving them too many things to look at. Visuals for online learning must give students some place to focus their attention during an oral presentation and reinforce the message of that presentation. You don’t want students wondering whether they should focus on the presenter, the whiteboard on which the presenter writing, the notes they were told to download before the presentation, or the fly on the presenter’s head.
Visuals for online teaching should teach.
If what you’re teaching lends itself to graphic images, that’s fine. Use them. But if what you’re teaching doesn’t lend itself to images, use the computer screen as the equivalent of the classroom white board or overhead projector.
The best visuals are mnemonic devices underscoring the lesson’s main takeaway. They don’t need to be works of art. They need only to communicate a message clearly. There’s nothing wrong with using text instead of images providing you limit the amount of content students must read at one time. Display text should reinforce your teaching, not be your teaching.
