I mean if there is a trend to start closing schools or dismiss school early for weather events, pretty soon nobody will be in school. If we're talking about the potential for a serious, life threatening event, then absolutely, close schools. I guess maybe it's hard to fully blame those making these decisions...they're making decisions based on what they're being presented and weather is flat out hyped.
The other thing too with early dismissals is they're pointless. Just cancel the day. I remember in school when we were having an early dismissal, nobody was paying attention. Classes were shortened, teachers had to rush to get through material...nobody is winning in those situations. It's a disservice to the teachers and its a disservice to the students.
I can't speak on the remote learning since I have zero experience with it (unless you want to count online classes ) but I feel like you have to be extremely disciplined to handle remote learning and how many middle/high school students fit that boat?
