In my webinar about quickly transitioning to teaching online (recording available here) I mentioned that I would using the scheduling feature in Gmail to send messages to students and parents on a consistent schedule. Here's a demonstration of how to use the scheduling feature in Gmail.
Applications for Education
You might be wondering why I would use this feature and not just use the scheduling feature in Google Classroom. The answer is that I have some students who prefer to have email sent to an email address other than the one issued by the school. Right now my priority is engaging my students in an online learning experience that we've been thrust into. Now is not the time for me to make a stand that says, "you must use your school email!" I'll fight that battle later. On a similar note, I have parents who despite repeated invitations won't join Google Classroom so I'm trying to meet them where they are.
