Activity Guide
Essential Guidance for Digital Safety & Wellbeing
Discussions about digital risk and misuse can surface sensitive or complex issues, including scams, privacy breaches, or harmful online experiences. These need to be handled with care and maturity.
Teachers should:
Present scenarios in a controlled and age-appropriate way
Avoid exposing students to real harmful content or live examples of malicious QR codes
Be mindful that students may disclose prior unsafe experiences
It’s best practice to:
Focus on empowerment and what students can do to stay safe, rather than fear
Reinforce clear, actionable habits like checking and evaluating context before interacting
Align discussions with school policies and other guidance around digital safety and wellbeing
