Three things I want my students to know about DC:
* effective methods to search for and check veracity of information on internet
* understand that a lot of content is provided free or paid for by advertising but that there is a lot more information available that has to be paid for by subscription or other means
* students should be aware of hazards of giving personal information on the internet
I work with the LA/SS/Science teachers on my team to be sure students are taught DC.
