I am sure that on-line etiquette needs to be taught in the classroom before students us Google tools. When on-line, students need to learn how to be respectful of other people’s viewpoints. If they should critique a viewpoint, they should also avoid personal attacks on the person who expressed the opinion, as well as the use of profanity. I think you brought up a very good point about internet privacy as well. For example, if a student reveals too much about his identity - - such as his address or other personal information- - it is impossible to retrieve those pieces of information. That is, teachers should instruct students how to responsibly guard their on-line identities. Also, as you stated, age-appropriate restrictions need to be covered extensively. Of course, this comprises pornography and other adult materials that can be found on-line. What do you think?
