The authors note that when it comes to balancing free speech and schools' responsibilities, the online world is largely uncharted waters. Questions remain about the rights of both students and teachers in the world of social media. Although the lower courts have ruled that students' freedom of speech rights offer them some protection for comments made on social media when they are outside of school, the U.S. Supreme Court has declined to accept any cases dealing with this issue. In the meantime, teachers appear to be held to a higher standard, and they should be aware that comments they make on social networking sites may make them vulnerable to charges of unprofessional conduct. Until the Supreme Courts decides these matters, educators should think of their social networking identity as an extension of who they are in the classroom, and to navigate with care as they venture into this new world.
