What this dot point is asking

This outcome is about being safe and responsible online. You should be able to describe safe online behaviour, protect your personal information and privacy, and respond sensibly to risks such as oversharing and cyberbullying. This is the heart of digital citizenship: using technology in a way that keeps you and others safe. In the written paper you list personal information to protect, explain why privacy matters, and describe responsible responses to online risks.

The answer

Protecting personal information

Personal information is anything that identifies you or could be used to find you, such as your full name, home address, phone number, school name and date of birth. You should be careful about sharing these online, because:

  • Strangers could use the information to find you or contact you.
  • Criminals could pretend to be you, which is identity theft.
  • Scammers could target you using details they have gathered.

Once something is posted, it can be copied and spread, so it is very hard to take back. Sharing less keeps you safer.

Privacy settings

Most apps and sites have privacy settings that control who can see your posts and profile. Setting your account so only people you know can see your information limits who has access. Check these settings, because the default is not always the most private.

Safe behaviour with strangers

People online are not always who they claim to be. Be cautious about messages from strangers, never agree to meet someone you only know online without telling a trusted adult, and do not send photos or personal details to people you do not know.

Cyberbullying

Cyberbullying is using digital devices or the internet to repeatedly hurt, threaten or embarrass someone, for example through mean messages, spreading rumours, or sharing embarrassing content. If you are cyberbullied:

  • Do not retaliate. Replying often makes it worse.
  • Keep evidence. Take screenshots so there is a record.
  • Block the person so they cannot contact you.
  • Tell a trusted adult such as a parent or teacher, and report it to the platform.

If you see someone else being bullied, support them and tell an adult rather than joining in or staying silent.

Examples in context

Example 1. A new social account. A student setting up a new account checks the privacy settings first, so only approved friends can see posts, and leaves out their phone number and school from the public profile. This limits who can find or contact them.

Example 2. Supporting a friend. When a classmate is targeted by mean group messages, a student does not join in or ignore it, but encourages the friend to save the messages, block the senders, and tell a teacher, and reports the group themselves. Responsible bystanders help stop bullying.

Try this

  • Cue. List four pieces of personal information you should be careful about sharing online. (For example full name, home address, phone number, school name, or date of birth.)

  • Cue. Explain why information posted online is hard to take back. (It can be copied, screenshotted and shared by others the moment it is posted, so deleting your copy does not remove the others.)

  • Cue. Describe two responsible actions if you are being cyberbullied. (Do not retaliate; keep evidence with screenshots and block the person, then tell a trusted adult and report it to the platform.)

Exam-style practice questions

Original5 marksList five pieces of personal information you should be careful about sharing online, and explain why protecting personal information matters.
Show worked answer →

Five pieces of personal information, for example: full name, home address, phone number, school name, and date of birth. Other acceptable answers include photos that show your location, your daily routine, or passwords.

Why it matters: personal information can be used by strangers to find you, to pretend to be you (identity theft), or to target you with scams. Once information is posted online it can be copied and spread, so it is hard to take back. Protecting it keeps you safer and keeps control of who knows what about you.

What markers reward: five genuine items of personal information, and a clear reason such as protecting against strangers, identity theft, or scams, plus the point that posted information is hard to remove.

Original4 marksExplain what cyberbullying is, and describe two responsible things a person should do if they are being cyberbullied.
Show worked answer →

Cyberbullying is using digital devices or the internet to repeatedly hurt, threaten or embarrass someone, for example through mean messages, spreading rumours, or sharing embarrassing content.

Two responsible responses, for example:

  1. Do not reply or retaliate; instead keep the evidence by taking screenshots, then block the person.
  2. Tell a trusted adult, such as a parent or teacher, and report it to the platform so it can be dealt with.

What markers reward: a correct definition of cyberbullying as repeated online harm, and two sensible responses such as not retaliating, saving evidence, blocking, and telling a trusted adult or reporting it.
