A question for the whole room
One story to open. A room full of ideas to test.
Ready in three steps
- Open the story.Read and try the first pages together.
- Pause for a prediction.At the story’s question, read its choices aloud. Invite a vote and ask, “What makes you think that?”
- Run it. Watch. Wonder.Choose the class’s prediction, run the experiment, and compare what happened with your guesses.
Different guesses are welcome. The experiment gives everyone something to rethink.
Something to put on paper
A one-page prediction and observation sheet. No answers included.
After the experiment: discussion notes
Talk about what happened
- Why is the modulo-17 clock useful for learning even though it is not a security recommendation?
- What is different about a passive listener and an active middle party?
- Why do approved group structure and parameter size both matter?
Where it shows up in real life
- A browser and website establishing fresh session keys
- A messaging protocol agreeing on ephemeral keys
- Secure tunnels that authenticate peers before carrying private traffic
