While at the MLTI workshop on digital citizen, we're spending a lot of time checking out Common Sense Media. It is an excellent resource for EVERYTHING involving technology, especially in 1:1 environments. One of the lessons I checked out included a video on your digital footprint. It's just over a minute long, so super quick and easy. I definitely recommend showing it to your students to get them thinking about what they are doing online and their lasting footprint. Perhaps include this as part of your research projects in class since it deals with how long information will be around online. I've embedded the video from YouTube below.
What do you think?
