AI Image Quiz for Teachers: A Ready-Made Lesson

This is a complete forty-five minute lesson on AI images that needs no preparation beyond opening a browser. Students play a round of the quiz, compare their scores, then work through the clues and the discussion questions below. No accounts, no installation, no student data collected.

Why this lesson works without a lecture

Students arrive convinced they can spot a fake, and the first round usually proves otherwise. That gap between confidence and score is the teaching moment: it is far more persuasive than a slide stating that young people overestimate their ability to detect synthetic media.

The lesson therefore starts with the game, not with a theory. Five minutes of play gives every student a personal number to argue about, and the rest of the session gives them the vocabulary to explain why they missed.

The 45-minute plan

Use the timetable as a guide rather than a script. Classes that argue a lot will spend longer on the discussion and can skip the homework briefing.

  • 2 min: students open the quiz on their own device and play one round on the medium level
  • 6 min: collect the scores on the board, note the highest and the lowest without naming anyone
  • 10 min: work through the four core clues (source, text, contact points, light) with two examples
  • 12 min: play a second round on the hard level and compare the two scores in pairs
  • 10 min: discussion questions below, in small groups
  • 5 min: agree on one rule for the class, for example 'we check the source before we forward'

If a class shares devices, the second round works well as a single projected round with a show of hands per image.

Discussion questions

These questions move the lesson from technique to judgement, which is where media literacy actually lives.

  • Why would someone publish an AI image without labelling it?
  • If a fake image tells the truth about how something felt, does that matter?
  • What would you need to see before you forwarded an image to a group chat?
  • Who is responsible when a generated image spreads: the person who made it, the platform, or the person who shared it?
  • Which is worse in your own feed: a fake you believed or a real photo you dismissed as fake?

What to tell students about the limits

Be explicit that detection is not a guaranteed skill and that no checklist survives the next model release intact. What stays stable is the habit: check the source, look for two independent clues, and say how sure you are.

It also helps to name the failure mode they will meet most often. It is not a perfect deepfake; it is an ordinary photograph with a wrong caption, or a real image from a different year attached to a new event. Manipulation is usually about context rather than pixels.

Privacy, devices and school policy

The quiz runs entirely in the browser. No account is needed, no email address is requested, and progress is stored locally on the device unless a student chooses to save a name for the leaderboard.

There is advertising on the public site, so check your school's policy before using it in class. If ads are not permitted, the discussion questions and the checklist page can be used on their own, without the game.

Frequently asked questions

Is the quiz suitable for school use?

Yes. It runs in the browser with no account and no personal data. Check your school's rules on advertising and on shared devices before the lesson.

Which age group is this lesson for?

It works from about year eight upwards. For younger classes, use the easy level and keep the discussion to the first two questions.

Do I need to prepare material?

No. Open the quiz, play one round, and use the timetable and discussion questions above. The tips page supplies the examples if you want them.

Can students play without accounts?

Yes. Every mode is playable without signing up. A name is only needed if a student wants to appear on the public leaderboard.
