Learning Objectives
What You'll Learn
By the end of this session, you will be able to:
- Identify the three core parts of a well-structured prompt: Context, Task, and Format
- Rewrite vague prompts into specific, structured prompts
- Compare before-and-after responses to see how structure improves quality
- Apply the Context + Task + Format framework to your own academic questions

Core Lesson
Today's Lesson
Read through this lesson carefully before starting the practice exercises below.
In Session 1, you learned that a prompt is the message you send to ChatGPT. Now it's time to learn the secret that separates good prompts from great ones. Here's the core insight: the more specific and structured your prompt, the more useful ChatGPT's response will be. It sounds simple, but most people — even experienced AI users — routinely underestimate how much a little extra detail changes everything.
Think about giving directions to a friend. If you say "Go to the store," your friend has no idea which store, how to get there, or what to buy. But if you say "Please drive to the Whole Foods on Main Street and pick up a loaf of sourdough bread — it's on the second shelf in the bakery section," your friend knows exactly what to do. Prompts work the same way. Vague prompts get generic responses. Specific prompts get targeted, useful responses.
There's a simple three-part framework that will transform your prompts immediately. We call it Context + Task + Format. Context tells ChatGPT who you are and what situation you're in. Task tells it exactly what you want it to do. Format tells it how you want the response structured — as a list, a paragraph, a table, bullet points, or any other form.
Here's an example. A vague prompt might be: "Tell me about dissertation writing." That's fine, but it's like asking someone to tell you about cooking — the answer could go a thousand directions. A structured version might be: "I am a doctoral student who has been ABD for two years and has lost momentum. Please give me a 5-step action plan to restart my dissertation writing, formatted as a numbered list." Notice the three parts: Context (ABD for two years, lost momentum), Task (give me an action plan to restart), Format (numbered list, 5 steps).
You don't need all three parts every single time — sometimes a simple question is perfectly fine. But whenever you need a specific, high-quality answer, the Context + Task + Format framework is your best friend. In your academic work, you'll use this structure constantly: when asking for literature summaries, writing feedback, research ideas, or help understanding difficult concepts.
The beautiful thing about this framework is that it's easy to remember and instantly applicable. From this session forward, every time you sit down to type a prompt, ask yourself: Have I given context? Have I stated the task clearly? Have I specified the format I want? If you can answer yes to all three, you're writing at a level that most people never reach.
Hands-On Practice
Practice Exercise
Follow these steps in ChatGPT. Take your time — there's no rush. Learning happens through doing.
- Go to ChatGPT and start a new chat. Type this vague prompt: "Tell me about research methods." Read the response.
- Now start a new chat and type the structured version: "I am a graduate student in social work. Please explain the difference between qualitative and quantitative research methods in 3-4 sentences, with one real-world example of each." Compare it to the first response.
- Try the second pair. Vague version: "Help me write better." Then structured version: "I am writing a personal statement for a graduate school application. Please review this sentence for clarity and suggest one improvement: 'My interest in education stems from many years of working with children in various settings.'"
- Try the third pair. Vague: "Tell me about aging." Then structured: "I am researching healthy aging for a graduate paper. Please summarize the top three evidence-based lifestyle factors that support cognitive health in adults over 60, formatted as a bullet-point list."
- Look at all three pairs of responses. Write down the biggest difference you noticed. How did adding Context, Task, and Format change the usefulness of each response?
- Bonus: Take a question you genuinely want answered about your area of academic interest and rewrite it using the Context + Task + Format structure. Compare both versions.

Summary
Key Takeaways
- The most effective prompts follow a three-part structure: Context (who you are and your situation), Task (what you want the AI to do), and Format (how you want the response structured).
- Vague prompts produce generic responses; specific prompts produce targeted, useful ones.
- You don't need all three parts every time — but for complex academic tasks, all three make a significant difference.
- This Context + Task + Format framework is the foundation for all advanced prompt techniques you'll learn in this course.
Adding Context and Format Instructions to Prompts
You've learned the Context + Task + Format framework — the single most important upgrade you can make to your prompts. From this point forward, every prompt you write can be stronger by simply answering three questions: Who am I and what's my situation? What do I want the AI to do? How do I want the response structured?
