I salute the dedication of teachers who go beyond, but I think this a very dangerous breach of privacy / work-play balance, and must be stopped.
Here's why: #Thread
When a teacher makes you join, there's no opt out. Everyone gets your phone number.
Teachers are using this as a tool to check who has seen their instruction to do some extra work they didn't think of in class. True story (seriously).
Kids are generally under enough pressure as it is. I think it's unhealthy for them to have to respond 24/7 in a medium with **instant** communication.
Ban Whatsapp groups (and the like) where teachers and students are in close personal contact. If you insist on allowing FB groups, groups only, no personal chat. Plus a third party observer in the group.
Too many kids have been hurt and damaged irreversibly.
No, I'm not claiming it will eradicate it. I am arguing that it sure as hell will minimise the avenues available to such predators and help *reduce* its occurrence.
