Lesson 1.4: What Are Large Language Models (LLMs)? in the AI for Teachers Certification Program.

Have you ever wondered how ChatGPT, Gemini, Claude, and other AI assistants can answer questions, generate lesson plans, write quizzes, or create classroom activities in just seconds?

In this lesson, you’ll learn what Large Language Models (LLMs) are, how they work, and why they have become the foundation of today’s most powerful Generative AI tools. Through simple explanations and classroom examples, you’ll understand how LLMs predict language patterns to generate human-like responses and how teachers can use them effectively to support teaching and learning.

By understanding how LLMs work, you’ll become a more confident AI user—writing better prompts, evaluating AI responses more critically, and using AI responsibly in your classroom.

In this lesson, you’ll learn:

✅ What Large Language Models (LLMs) are
✅ How ChatGPT and other AI assistants generate responses
✅ Why LLMs sometimes make mistakes or “hallucinate”
✅ The relationship between LLMs and Generative AI
✅ Practical classroom applications of LLMs for teachers
✅ Why teachers should always verify AI-generated content

This lesson is part of Module 1: AI Literacy for Teachers, designed to build a strong foundation before learning Prompt Engineering and advanced AI applications in education.
