As recent email from the provost’s office and Digital Learning suggest, bandwidth may become an issue with video-conferencing applications like Canvas Conferences. Daniel Stanford at the IDDblog from DePaul makes some important points and has valuable suggestions about low(er) bandwidth options for remote teaching.

For one-on-one and group asynchronous conversation, you might consider the smartphone app Marco Polo. It’s basically facetime, but asynchronous. You can record a video message, send it out to people on your list, and they can then watch it and reply to you at their convenience. You get the vibe of face-timing without the need for the person to be there when you call. Pretty cool.
