Have you read your school's digital citizenship policy?
Do you focus on the positive, not only negative ways technology being used? There needs to be balance!
Are you weaving digital citizenship conversations in meaningful ways in all classes? (Not just in "computer class")
Do you connect your lessons to ways they use the technology at home as well?
Do you know how your students use technology outside of school time as well? If not ask them what they are doing and explore it yourself or have them show you. Knowing how they are using technology will give you a better insight to what lessons on digital citizenship you should focus on.
Are you modelling how to be a good digital citizen for your students? Kids need positive roles models, you can model how you are a positive digital citizen by sharing your own digital footprint. Google yourself...what shows up? If it is nothing, consider starting a Twitter, Google Plus profile, blog or create your own website to share your work or great resources you use. Share this with your students.
How are you getting parents & families involved in the conversation? Send home information about what students are learning about digital technology or hold a parent digital citizenship night.
Do you know the terms of service for the digital tools you are using? Who owns the work your students create?
Are there safety concerns when using a digital tool? How will you assure your students are safe?
