This new case of a teacher—middle school—going at it with students: she used e-mail to make it all happen. I’ve had this conversation with teachers and administrators before: I really don’t think teachers should give students their e-mail addresses. Schools should have policies about it, and that would be mine. It just makes sense, it seems. I’ve heard homework help justifications for e-mailing, but it’s not necessary and it’s too easy for problems to arise. Common sense.
