This poster is part of my free course on online privacy and safety which I am working on for my Masters on Online Learning and Teaching. This can be printed and posted in the classroom, explaining to students some of the basics regarding different files and how to protect their computer from bad files. Online safety and privacy is a difficult, but important topic to tackle with students. The full course includes topics such as cyberbullying, respect for others and oversharing. For more on this, please visit www.ewarrior.ca -- course to be completed May 2018.
