Here is an example of a teaching session designed to develop critical thinking skills:
“True or false?” — Spotting an AI-generated video
Step 1 — Icebreaker (5 mins) Without saying a word, show two short videos side by side: one real, one generated by AI. Ask just one question: “Which one is fake?” Let the pupils vote by a show of hands. The aim is to create a surprise – many get it wrong, and that’s exactly where we start.
Step 2 — Creating the scenario (8 mins) Open ChatGPT (or another AI tool) live in front of the class. Ask it to write a fake, sensational video title on a topic that appeals to the pupils (sport, music, video games, etc.). Show how quickly and convincingly it does this. Ask the question: “If you saw this on TikTok, would you believe it?“
Step 3 — Compiling a list of clues (10 mins) Working in groups, pupils discuss what made them suspicious about the fake video: unusual movements, blurry hands, a robotic voice, inconsistencies in the background… The teacher notes these down on the board. Together, they draw up a mini-checklist of 5 to 6 key points to look out for.
Step 4 — The right reflex (7 mins) Spend two minutes explaining the 3V rule: Verify the source, Verify elsewhere, be wary of emotional dizziness (things that shock or stir strong emotions are often designed to stop us thinking). The pupils copy the checklist onto a sticky note to stick in their notebooks.
What they take away with them: a practical checklist, the memory of having seen the machine generate fake news in real time, and the instinct to think twice before sharing.
