(or: How to Talk So AI Actually Listens)
Imagine you’ve been asked to give instructions to a very fast, very clever, but extremely literal robot.
It won’t guess what you mean.
It won’t fill in the gaps.
It will do exactly what you ask — no more, no less.
That robot is AI.
A prompt is simply the instructions you give it. The better your instructions, the better the result. Here are the key ingredients that turn a weak prompt into a powerful one.
Below are five techniques to writing good prompts for an AI. For each one there is a short exercise in the worksheet. Read the section and then tackle the excersise in the worksheet.
Vague instructions = vague answers.
If your prompt is fuzzy, the AI has too many ways it could respond. Clear details narrow the possibilities and improve the output.
❌ Bad Prompt - “Write about dogs.”
Too general. What kind of dogs? What style? Who is it for?
✅ Better Prompt - “Write a short, exciting story about a brave golden retriever who saves a lost kitten during a thunderstorm. The story should be aimed at 8-year-olds.”
Now the AI knows:
the animal
the genre
the audience
the tone
👉 Rule of thumb: If a human would ask a follow-up question, the AI probably needs more detail.
Tell the AI why you’re asking.
Context helps the AI choose the right kind of answer, not just a correct one.
❌ Prompt Without Context - “What can I do in France?”
That could mean tourism, school work, history, food, or something else entirely.
✅ Prompt With Context - “I’m planning a trip to Europe for a school holiday. For my itinerary, what are three must-see places in France, and why are they popular?”
Now the AI understands:
the purpose
the situation
the type of answer you want
Tell the AI who it is pretending to be.
This helps control tone, vocabulary, and depth.
❌ Prompt Without a Role - “Explain photosynthesis.”
You might get something too technical… or too simple.
✅ Prompt With a Role - “You are a friendly science teacher explaining photosynthesis to a Year 9 class. Use simple language and one real-world example.”
Now the AI knows:
who it is
who it is talking to
how complex the explanation should be
💡 This is one of the most powerful prompt techniques.
Don’t just ask for information — ask for a shape.
AI can write in almost any format, but only if you tell it what you want.
❌ Prompt Without Format - “Tell me about the planets.”
Paragraph? Essay? Random facts?
✅ Prompt With Format - “List the planets in our solar system starting from the closest to the Sun. Present the answer as a bulleted list. Include one interesting fact for each planet.”
Now you’re guaranteed:
the order
the structure
the amount of information
Rules make answers better, not worse.
Constraints stop the AI from wandering off or giving too much information.
✅ Prompt With Constraints - “Write a short poem about friendship. It must have four lines, rhyme AABB, and not mention any specific names.”
This controls:
length
structure
content
Paradoxically, limits often make outputs more creative.
