Teachers in Louisiana may soon think twice before sending a text message or e-mail to a student from a personal electronic device. A new state law requires all Louisiana districts to implement policies requiring documentation of every electronic interaction between teachers and students through a nonschool-issued device, such as a personal cellphone or e-mail account, by Nov. 15. Parents also have the option of forbidding any communication between teachers and their child through personal electronic devices. Similar policies exist in many school districts across the country, and at least one other state has considered such legislation in recent years. Critics question the measures, saying they will likely restrict appropriate communication between teachers and students and discourage the use of new technologies.
