1. Three things I would want my students to understand about being good dual citizens:
a. Understanding that once you post information on the internet, it is hard to erase. Odds are that someone already saw what you posted and it's too late to take it back. Be careful what you post!
b. The internet is a scary place, because you never know who is looking up information about you or where you live, what you're doing, etc. Be smart and stay safe!
c. Plagiarism is another important factor when it comes to the internet. Students need to realize they cannot just copy and paste someone else's words. Now, we have things like turnitin.com and students understand more about it.
2. I think the Texas School Safety Center link from Texas State is very educational. It would be good information to use when talking about internet safety. It provides different lesson plans, guides, and tips on all kinds of things such as cyber bullying and video safety, etc.
3. I would "teach" the idea of digital citizenship by having an open ended discussion of what the students considered to be appropriate vs. inappropriate. I would also want to show some YouTube videos that pertain to internet safety. Visuals are a good stimulus for most students.
4. I plan to share the idea with the student's parents by sending home a letter/contract that explains everything about digital citizenship and how we plan to use the internet in class. There would be a page that requires a parent signature, so I would know which students were allowed to use the internet and vice versa.
