Lesson 1 of 2
How AI actually learns
Train, test, fix.
How do you know which is which? Who showed you?
Teacher: Take three answers. Pairs first, or let them draw.
A computer program can be built to find patterns in examples too.
It does not understand fruit.
It finds patterns.
Four steps. Chapter 3 in the guide.
- 1Collect dataGather lots of examples.
- 2Label dataPeople write what each one is.
- 3TrainThe program looks for patterns.
- 4TestTry it on new examples.
An AI is a computer program.
It does not understand things.
It finds patterns in examples that people give it.
Zibs & Zobs
Nobody tells you the rule.
- Round 1 · look at 12 labelled cards, then test
- Round 2 · new cards, same test
- Round 3 · fix it: draw 4 new cards
Teacher: Hand out the envelopes and role cards. Say: “I will not tell you the rule.” Whole class? Use the next slides instead of cards.
Round 1: learn from these 12 cards
Test cards: Zib or Zob?
Teacher: Use these for rounds 1 and 2. Ask the Tester of each group to call it, or vote with thumbs.
Round 2: new cards, same test
Round 3: fix it
Draw 4 new cards to add to the second set.
The AI should not be fooled any more. Then test again.
Talk in pairs, then share
- Which round scored best? What did the new cards change?
- Who chose the cards?
- What would you change to make round 2 fair?
Exit ticket: pick one
- Draw a Zib and a Zob.
- Tick a face: got it, almost, not yet.
- Write: “The AI got it wrong because …”
The rule (reveal after the rounds)
Zib = pointy ears / Zob = round ears
Spots and tails varied on purpose. In round 2 every Zib had spots, so spots looked like a clue too.
Teacher: Test cards 1 to 6: Zib, Zob, Zib, Zob, Zib, Zob.
