1. I would like for my students to understand that they must use common sense and be safe on the web. Another thing they need to know is not to plagiarize! I'd also like them to really take it seriously when we say don't share your passwords and be careful on what you post: it can come back to haunt you for a very long time!
2. I like Atomic Learning because it can teach you what you want to know fast! I think I can use that a lot in the classroom.
3. I would "teach" digital citizenship by first telling them the rules and why they are the rules, then discussing it, and then letting them see what happens if they violate those rules.
4. Parents also need to know about digital citizenship because they need to reinforce this at home. I would tell them at Open House, in a newsletter, on my website, or relay it via the kids.
