No mention whether this was a social ir work Facebook account. When I worked for KIPP Schools, many teachers had two accounts and kept their teaching Facebook page clear or their personal lives. Facebook can be very useful tracking students during. What is going on in a students social life can absolutely affect their learning. Public schools don’t really care, they don’t go the extra mile, and most simply want the kids to show up so they get paid. Once they graduate, they could care less. KIPP was the opposite. They went as far as to track their students in college and offer assistance. Its no wonder their are crushing the public school model.
Our Catholic schools have a dedicated website for student-teacher interaction and it is forbidden for them to contact each other using private email, Facebook, etc.
I think it keeps it professional, as it should be.
