Lesson · Design thinking & clear communication
Write the brief
Students learn that a good prompt is really a design brief, the same kind of document engineers and product managers write every day. A vague request gets a generic result; clear thinking gets a useful one.
The big idea
The clearer your thinking, the better any tool, or any teammate, can help you.
Students will be able to, without AI:
- Define a problem, audience, constraints and success criteria
- Write a brief someone else could act on
- Judge outputs against their own criteria
- Explain why clear specifications matter in real jobs
Lesson flow · the 5 P’s
Think first. Then the tool.
Most of the lesson happens on paper. AI appears for one short, structured phase, and the teacher can run it from a single projector screen. How the 5 P’s work →
Ponder
10 min○ Screens off · paper onlyTeams pick a real design challenge from school life.
- Choose one: a poster that gets more students to the science fair; a better lunch-line system; a sign that reduces hallway crowding.
- Who is it for? What problem does it solve?
- What must it include? What must it not do?
- How will you know it works? Write two success criteria you can check just by looking at a draft (for example, “the date and room can be read from 10 feet away” or “a new student could follow it without help”).
Plan
10 min○ Screens off · paper onlyTeams write a one-page brief on the worksheet.
- Goal · Audience · Must have · Must not · Constraints (size, budget, time) · Tone or style in words · How we’ll judge it.
- Trade briefs with another team: could they build it from your words alone? Revise.
Partner
10 min● AI on · teacher screen or labEvery team needs two results for its own challenge: one made from a vague one-line request and one made from its brief.
- With devices (a lab, or time on the teacher’s screen): run both prompts for every team. Each team sketches or notes its two results.
- One screen and not much time? Run both prompts for one team as a demo. Then each team “plays the AI” for another team: one quick draft from the one-line request alone (2 min), then a second draft from the brief alone, with no questions allowed (4 min). Both drafts go back to the team that wrote the brief.
- Students note differences between the vague and the briefed result.
Probe
7 min○ Screens off · paper onlyScreens off. Each team scores its own two results against its own success criteria. (If another team played the AI, “the AI” below means that team.)
- Score each result 1–4 on each criterion.
- What did the vague prompt force the AI to guess?
- What did the AI still get wrong, even with the brief?
- What would you change in your brief next time?
Prove
8 min + homework○ Screens off · paper onlyTeams present the journey, then reflect.
- Two or three teams present, 2 minutes each: our brief → what came back → what we changed → our final idea.
- Every team writes its reflection on the worksheet: where else is a clear brief useful? (Group projects, jobs, asking a teacher for help.)
- For homework or next class: build or sketch the final version by hand.

Student worksheet
Print one per team, or one per student if each student keeps a copy of the team brief. Everything students hand in is handwritten, so their thinking is visible.

Clear thinking in, useful results out.
Assessment
Grade the thinking, not the output
Every row scores something students did themselves. An AI can produce a product; it can’t produce a student’s reasons.
| Criteria | 4 · Excellent | 3 · Solid | 2 · Developing | 1 · Beginning |
|---|---|---|---|---|
| Problem definition | Specific goal, audience and success criteria | Clear goal and audience | Vague goal | Missing |
| Brief quality | Another team could act on it without questions | Mostly actionable | Several gaps | Not usable |
| Evaluation | Scores outputs fairly against criteria and explains | Scores outputs | Opinion only | None |
| Iteration & reflection | Improves the brief and connects to real work | Improves the brief | Minor changes | No reflection |
Why this is hard to cheat
Students are graded on the brief, the scoring and the reflection, all done by hand. The AI output is something to score, not something a student hands in as their own.
Adjust it
Younger students: Use a fill-in-the-blank brief with pictures. The teacher compares a vague and a detailed drawing request.
Older students: Write a real product requirements document for a school app idea, including user stories and what the first version will leave out.
No devices at all? Teams play the AI for each other, as in Partner, so every team still gets two results to score. To show real AI output too, print a vague and a briefed result for each of the three challenges in advance.
Discussion questions
- Why does a vague request get a generic result, from a person or an AI?
- Who writes briefs in real jobs? (Engineers, product managers, architects, film directors.)
- What’s the difference between telling AI what to do and thinking for it?
- How could a clear brief help in a group project?
