AI 101
A clear guide to what generative AI is, how it processes information, how to apply it, and how to choose the right platform.
How a Large Language Model Works
The artificial intelligence platforms in widespread use today, such as ChatGPT, Claude, and Gemini, are built on foundations known as Large Language Models. Despite their impressive capabilities, these systems do not possess genuine comprehension. Instead of comparing a model to an expert colleague, it is more accurate to view it as an exceptionally advanced autocomplete engine that operates at a massive scale.
While this comparison may seem to simplify the technology, it describes the core mechanism that drives every output. You can observe this process unfold in two main steps.
It processes tokens instead of words
Before processing your request, the model divides your text into units called tokens, which are typically about the size of a syllable. For example, a word like ‘Photosynthesis’ is split into two distinct tokens. The model works exclusively with these numerical representations rather than complete words.
It predicts the subsequent token and repeats the cycle
Every great lesson starts with a
To generate text, the model evaluates and ranks every possible next token. Select the highest-probability option below to see how it constructs a response.

token 0 of 5
Trained on text
The model was trained on billions of pages of books, websites, and code. Through this exposure, it learned to recognize linguistic patterns rather than actual meaning.
No real understanding
The system has no personal beliefs, awareness, or consciousness. It performs highly sophisticated pattern matching, which is its sole method of operation.
Starts fresh each chat
The model does not retain memory of past interactions once a chat is closed. Each new conversation begins as a completely blank slate.
Capabilities for Educators
Artificial intelligence is highly effective as a drafting partner and an administrative accelerator, but it should not be treated as a final authority.
Lesson Planning
Draft comprehensive lesson plans, clear learning objectives, and scaffolded classroom activities within seconds based on a brief description of your unit.
Differentiation
Adapt a single reading passage for multiple comprehension levels or generate tiered study questions for different groups of learners.
Feedback Drafts
Create initial drafts of student feedback that you can personalize and refine, which can reduce your grading time significantly.
Assessment Design
Develop quiz questions, analytical rubrics, exit tickets, and engaging discussion prompts aligned with specific academic standards.
Research Synthesis
Summarize lengthy documents, extract key arguments from complex texts, and discover connections across multiple reference sources.
Admin & Communication
Draft emails to parents, design meeting agendas, summarize policies, and prepare reports, then easily edit the text to match your personal voice.
You + AI: Distributing the Workload
To get the most out of these tools, use the AI to generate rapid first drafts while you focus on the aspects of teaching that require human expertise.
AI handles
The first draft
Volume
Generate multiple variations of a worksheet, draft several discussion prompts, or adapt a reading passage for different comprehension levels.
Speed
Produce a working draft in seconds, bypassing the initial hurdle of a blank page.
Structure
Build standard rubrics, email templates, meeting agendas, and structural outlines that you can easily customize.
Treat every output from the model as a preliminary draft.
You stay in charge of
Every decision that matters
Judgment
Determine what fits your specific class, your students, and the immediate context of your lesson.
Accuracy
Identify and correct incorrect information, since no material should reach students without your review.
Relationship
Provide the trust, empathy, and personal connection that no automated model can replicate.
You are the primary educator, and the model serves as your assistant.
What AI Cannot Do
Recognizing the limitations of generative models is just as critical as understanding their utility. These characteristics are not temporary bugs; they are fundamental to how large language models operate.
Verify the accuracy of its own output, which means it can confidently present incorrect information.
Substitute for professional teaching judgment regarding individual student needs.
Understand background context that was not explicitly provided in your prompt.
Engage in critical thinking or reason from first principles.
Access the live internet unless the specific platform is equipped with search tools.
Retain memory or context between separate chat conversations.
The RTCF Framework
A prompt is a set of instructions. The quality of the final output is directly determined by the detail and context you provide to the model.
Role
Identify the specific persona the model should adopt.
"You are an experienced 8th-grade English teacher."
Task
State exactly what you want the model to produce.
"Write a 5-question reading comprehension quiz."
Context
Provide the necessary details and background information.
"The text is a 600-word excerpt about the water cycle for 6th graders."
Format
Define the structure and style of the output.
"Use multiple-choice format, one correct answer per question, no answer key."
Weak vs. Strong Prompts
Weak — Lesson Planning
Write a lesson on photosynthesis.
Strong — Lesson Planning
You are a high school biology teacher. Write a 45-minute lesson plan on photosynthesis for 10th graders. Include a warm-up activity, direct instruction notes, a group activity, and an exit ticket. Align objectives to NGSS standard HS-LS1-5.
Weak — Feedback
Give feedback on this essay.
Strong — Feedback
You are a writing coach. Read the student essay below and provide three specific, encouraging pieces of feedback. Focus on argument structure and evidence use, not grammar. Write directly to the student in a supportive tone. [paste essay here]
Weak — Differentiation
Simplify this text.
Strong — Differentiation
Rewrite the following paragraph at a 4th-grade reading level. Keep all key vocabulary terms but define them in parentheses the first time they appear. Preserve the original meaning. [paste paragraph here]
Prompt Templates
You can copy, modify, and apply these templates to simplify common teaching tasks. Use the bracketed placeholders to insert your specific details.
Choosing the Right Tool
There is no single superior platform. The best choice depends on your school's existing software ecosystem, your budget, and the task at hand.
ChatGPT
OpenAI
Strengths
- Versatile across nearly every teaching task
- Voice conversations and image generation
- Deep Research for sourced, in-depth reports
- Custom GPTs for repeatable workflows
Claude
Anthropic
Strengths
- Excels with long documents and large context
- Nuanced, precise writing and feedback
- Strong reasoning and instruction-following
- Projects keep class materials organized
Gemini
Strengths
- Native Google Workspace integration
- Real-time web access
- Multimodal across text, image, audio, and video
- Google Classroom compatibility
A note on choosing
If your school environment runs on Google Workspace, Gemini is a natural starting point because it integrates directly with your existing tools. For general exploration, ChatGPT is widely supported and has a vast catalog of community tutorials. When your tasks require deep analysis of long documents or precise, complex writing, Claude often delivers the most reliable performance.
