Digital Citizenship can be defined as the "responsible use of [digital] technology... to engage with society on any level". In other words, Digital Citizenship is the action-oriented application of media literacy skills. This can include the safe and ethical use of digital technology, educating others about these issues, and advocating for better policies and protections for digital media and devices.
Common Sense Media is celebrating 11 years of its Digital Citizenship Week, which happens October 16-20, 2022. Visit their webpage for information and resources.
