I think it is important for all students to understand the need to be good digital citizens. It is important that they are safe, that they are not internet bullies, and that they send only appropriate content when using their school issued email.
I would recommend the Texas School Safety Center to students and parents. It is easy to maneuver and the links provide good instructional materials for parents, students, and teachers. I would think that posting the link to this chart on my website would be a good idea for me to do. This way parents and students could access it easily.
