Digital Citizenship Week
Every third week in October，schools around the world celebrate Digital Citizenship Week （数字公民周），which focuses on the healthy and responsible use of online technology. This was originally created by Common Sense Education. It is the time for students to know about their digital footprints（足迹） and why they matter so that they can develop good digital citizenship.
During the week，the teachers always stress the importance of digital citizenship. It involves online safety，speaking up against cyberbullying（网络霸凌），protecting personal information，respecting copyright law and more. Good digital citizenship helps students understand the importance of balancing technology use with other non-digital activities. It also encourages students to connect with one another and create long-lasting relationships online. The key idea behind good digital citizenship is to treat other people，places，and things with respect.
However，students might not understand what information is not safe to share on social media，how to properly check sources，and the possible results of having online communications. Helping students understand digital citizenship helps them to manage Internet risks and succeed in the digital world. Teachers need to think about how digital citizenship is taught and learned in the school. There are some useful resources and models on the Internet that can help teachers develop a digital citizenship framework and program.
One of the important things of digital citizenship that students need to understand is their digital footprints. Every person who uses the Internet has a digital footprint. Because digital footprints can't be erased，students' digital footprints have the possibility to influence their whole life. Students' digital footprints can also leave them easy to get social engineering attacks or cyberbullying.
Since digital footprints may influence students' online safety，some suggestions are necessary for them. For example，they need to clear cookies（网络浏览数据） from time to time. They should also be careful about what they share with online service providers，and who they share their information with. The most important thing is that they should be responsible for what they post on social media.
