# Challenge: choosing rules or learning

Lesson 35 of 36 in **AI, explained** (AI101), unit "Auditing systems for responsible use". An open lesson from Maestro College.

## What the learner will be able to do
- Build a hybrid system that sends inputs to written rules first, then to a learned classifier, and to a person when the classifier's confidence falls below a cutoff chosen by trying several values on tuning data and keeping the lowest total of errors and reviews.
- Choose between rules, learning or a hybrid for a new problem, citing at least two reasons from evidence such as error rates, group gaps, inspectability and available data.
- Represent a new problem as states, moves, a start and a goal, and predict by tracing a tiny example whether breadth-first or depth-first search fits it.

## Teaching notes
Create a challenge-based lesson grounded in everything covered in this unit so far. Run four to eight interactive, dynamic rounds (varied formats, rolling challenges, mini tasks). Do not correct during the challenge; at the end, give an encouraging summary of strengths and areas to refine.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 35 complete: Challenge: choosing rules or learning."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "Challenge: course wrap-up and next steps" (lesson 36 of 36), and give the learner its link: https://open.maestrocollege.edu/ai-explained/challenge-course-wrap-up-and-next-steps.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
