At the Risk of (Briefly) Stating the Obvious

For those of you carrying an M-series iPad or Mac into the classroom and plugging into a projector, turn on Stage Manager. You will be able to keep your screen private (letting you access things that might violate FERPA or do searches on the web that make you hesitate).

While you are setting up Stage Manager, schedule a Focus Mode to turn on for class. This prevents all sorts of badly timed messages from accidentally disrupting class.

Not that I have ever done something like that to my wife.

These two small settings changes let your devices improve the quality of your life in the classroom.
