2.1 – Prompt Engineering 101 for ChatGPT, Gemini, Copilot Lesson

Lesson Overview

Prompt engineering is the core technique for getting useful results from generative AI models. If you’ve ever felt that responses from ChatGPT, Google Gemini, or Copilot were too generic or not tailored to your needs, there’s a solution—how you ask makes all the difference. This lesson gives you a foundational look at what prompt engineering is, why even small changes in your question can transform your results, and offers you seven best practices to start using immediately.

You’ll see why stating your goal leads to better answers, how specifying the desired format saves you time editing results, and why following up is often necessary. This lesson is especially valuable if you use AI models for projects, content creation, education, or research—anywhere clear information is crucial. For example, instead of simply asking, “Tell me about dogs,” you’ll learn to request “List five dog breeds with a characteristic of each, in bullet points.” These approaches can make your interactions with AI more predictable and helpful.

Who This Is For

This lesson is suited for anyone who wants more accurate outputs and less frustration when working with AI language models. It’s designed for:

• Educators seeking tailored explanations for students
• Content creators aiming for high-quality, relevant material
• Business professionals looking for actionable responses
• Researchers needing clear, cited information
• Students wanting reliable answers for assignments
• Anyone curious about improving their AI interactions

Where This Fits in a Workflow

You’ll use prompt engineering at the very start of any project involving AI—whether drafting articles, preparing study notes, generating business proposals, or brainstorming ideas. Strong prompt engineering turns an AI tool from a generic assistant into a focused collaborator. For instance, you might use this skill to generate step-by-step guides for your work, or to summarize research in formats that are easy to share. By mastering these basics now, you lay the groundwork for more advanced use cases later in the course.

Technical & Workflow Benefits

Before learning prompt engineering, you may have relied on trial and error, repeating vague questions and receiving unhelpful answers. The approach in this lesson is different: crafting clear, purposeful prompts so the AI understands exactly what you need. This reduces the need to rephrase or repeat requests, saving significant time. For example, instead of repeatedly clarifying “Tell me more,” you can specify upfront, “Provide a summary in three bullet points suitable for a beginner.” In content creation, this means you get directly usable drafts with less editing. For students or professionals, it reduces confusion and improves the reliability of your outputs. Across use cases, prompt engineering leads to faster, clearer, and more relevant AI responses.

Practice Exercise

To reinforce your understanding, try this practical activity:

• Choose a topic of interest—such as “photosynthesis,” “healthy meal ideas,” or “project management tools.”
• Write a vague prompt (e.g., “Tell me about photosynthesis”).
• Then, rewrite it using at least three best practices from the lesson—make it specific, state your intent, and ask for a bullet-point list.
  

After comparing both AI responses, which prompt gave you a more useful answer? Reflect on the differences and consider how applying best practices improved the output quality.

Course Context Recap

Prompt Engineering 101 marks your transition from passive user to active driver of generative AI. Previously, you learned what generative AI is and saw the wide range of models available. In this lesson, you gain the essential techniques to ask smarter questions—key for all your upcoming work with AI tools. The next lessons will build on this foundation, showing you how to apply best practices to increasingly complex projects.
