I suggest a flipped approach for on-line educaiton, which supplements text and pre-recorded material with live participation. While video conferences, webinars, and live streaming of video with synchronous participation are popular, these makes demands on the national network infrastructure, which may not be sustainable over the coming months. This not to say don't use video conferences and live streaming, but don't depend on them working.
ps: Last year I had a project for streaming with synchronous participation, in a way which would be tolerant of network problems. Unfortunately this work has been suspended due to the pandemic emergency, so I don't have a usable product.
