Concerns about how Facebook has used its users' data have some users pledging to delete their accounts. However it may not be that easy, as schools, teachers, and even parent teacher organizations use Facebook pages to deliver news about what is going on at school or to highlight activities. Some high school teachers also use Facebook as a way to communicate with class members, answer student questions after hours and even enhance instruction. While many schools and teachers have moved on to other apps and learning management systems, it still raises the question of whether or not it is necessary to have a Facebook account.
