Here's a short presentation to get your students safe online. February being the International month for being safer online, I am sure this resource will be useful as an introduction for the Safer Internet Day.
It contains 7 slides with
1. an introduction about the use of digital media (How students use the Internet, which services and apps they prefer)
2. a reflection slide about the benefits of the new technologies
3. a reflection about the dangers involved in the use of technologies
