Module Review Questions
What does it mean to learn?
How is a learning machine different from a programmed machine like a traffic light?
Why do scientists need to label their training examples?
A machine trained mostly on snowy wolf photos thinks snow means wolf. What kind of problem is this?
Lena trains a learning machine on bird photos. Leo trains the same type of machine on weather data. What will be different about their machines?
What do a child practicing a skill and a machine training on examples have in common?
You now understand one of the most important ideas in modern technology. Machines that learn are all around us — in our phones, apps, and computers. And now you know exactly how they work: examples, labels, guessing, checking, adjusting, and getting better. You are already thinking like an AI scientist!
Teach It to Someone Else
- The best way to know you really learned something is to teach it to someone else!
- Find a friend, sibling, or family member who has not done this module.
- Tell them three things you learned — in your own words, not reading from notes.
- Then give them this mini-challenge: name one machine in your home and decide together if it is a learning machine or a programmed machine.
- Finally, explain to them what bias is and why it matters.
- If you can explain all three of those things clearly, you have truly learned the material — and you are ready for the next module!
