Theme: Artificial Intelligence

Artificial Intelligence, or AI, is no longer only a technology topic.

It is now an English topic.

Secondary 3 students may meet AI-related ideas in essays, oral discussions, comprehension passages, visual texts, speeches, argumentative writing, expository writing and current-affairs questions. A student may be asked to discuss whether AI helps education, whether robots can replace humans, whether technology affects creativity, or whether people should trust machine-generated information.

To write and speak well about AI, students need the right vocabulary.

Not only simple words like “robot”, “computer” and “technology”, but more precise words such as “automation”, “algorithm”, “bias”, “verification”, “authenticity”, “surveillance”, “efficiency”, “dependence”, “creativity”, “ethics” and “accountability”.

For Secondary 3 English, vocabulary is not about using difficult words for decoration.

Vocabulary is control.

The right word helps students explain the idea more clearly, argue more precisely and sound more mature without becoming unnatural.

This list gives Secondary 3 students 100 useful AI-themed vocabulary words, with meanings and example sentences.

How to Use This List

Students should not memorise all 100 words in one day.

A better method is to learn them in groups.

Use these words for:

composition writing
situational writing
oral discussion
comprehension answers
argumentative essays
expository essays
discursive essays
current-affairs examples
AI and technology topics
education and future-work topics

A good student should know not only the meaning of a word, but how to use it naturally in a sentence.

For example:

Weak sentence:

“AI is good because it helps people.”

Stronger sentence:

“AI can improve efficiency by automating repetitive tasks, but overdependence on technology may weaken human judgement.”

The second sentence is stronger because the vocabulary is more precise.

Sample Secondary 3 Paragraph Using AI Vocabulary

AI can be a valuable tool in education, but students must use it with discernment. On one hand, AI improves efficiency by helping students summarise notes, generate practice questions and receive quick explanations. However, overreliance on AI may weaken independent thinking if students copy responses without understanding them. Another concern is accuracy, as AI output may sound confident even when it is unsupported or outdated. Therefore, students should treat AI as a supplement to learning rather than a substitute for effort, judgement and verification.

Common Mistakes When Writing About AI

Mistake 1: Saying AI Is Simply Good or Bad

AI is complex.

Better writing should show both benefits and risks.

Weak:

AI is good because it helps people.

Stronger:

			
AI can improve efficiency, but its benefits depend on how responsibly people use it.

Mistake 2: Using Big Words Without Control

Do not use words only because they sound impressive.

Weak:

AI gives humanity technological optimisation for intellectual transformation.

Stronger:

			
AI can help students learn faster, but they must still check whether the information is accurate.

Mistake 3: Forgetting Human Responsibility

Do not write as if AI acts alone.

Humans design, use, regulate and depend on AI.

Better sentence:

The problem is not only the technology itself, but how humans choose to use it.

Mistake 4: Trusting Fluency Too Easily

AI may sound fluent but still be wrong.

Better sentence:

Students should not mistake fluent language for reliable information.

Oral Discussion Practice Questions

Students can practise using the vocabulary list with these questions:

Should students be allowed to use AI for homework?
Can AI replace teachers?
Does AI make people more creative or less creative?
Should schools teach students how to use AI responsibly?
What are the dangers of relying too much on AI?
How can students check whether AI-generated information is accurate?
Should companies be accountable when AI systems make mistakes?
Will AI create more opportunities or more inequality?
How can humans protect originality in the AI age?
What human qualities are still important even when machines become smarter?

Final Takeaway

For Secondary 3 students, AI is an important theme because it connects technology, education, work, creativity, ethics and society.

The goal is not to memorise difficult words blindly.

The goal is to use precise vocabulary to think clearly.

A strong student should be able to explain both the benefits and risks of AI. They should know how to discuss efficiency, dependence, bias, privacy, misinformation, authenticity, creativity, accountability and human judgement.

In the AI age, English vocabulary is not only about sounding impressive.

It is about thinking accurately.

The better the vocabulary, the clearer the thinking.

The clearer the thinking, the stronger the writing.

30 Examples of Fence Vocabulary for Prompting

Why Precision Matters When AI Uses Normal English Like Programming

AI makes English behave differently.

When we speak to another human, the person may understand our mood, background, context, intention, relationship and hidden meaning.

But when we prompt AI, English becomes closer to programming.

It is not exactly computer code, but it works like a soft command language.

This means every word in a prompt can act like an instruction.

A vague prompt gives the AI too much freedom.

A precise prompt builds fences.

These fences tell AI:

what to include
what to exclude
how detailed to be
what tone to use
what level to write for
what assumptions to avoid
what format to follow
what evidence to use
what audience to write for
what output to produce

This is why students need Fence Vocabulary.

Fence Vocabulary is the set of words that helps humans control AI output using ordinary English.

Why Precision Matters

AI is trying to turn normal English into executable instruction.

When a student writes:

Write about AI.

The instruction is too open.

The AI must guess:

For what age?
For what subject?
For what format?
For what purpose?
For what audience?
How long should it be?
Should it be formal?
Should it include examples?
Should it argue for or against?
Should it be simple or advanced?

A more precise prompt says:

			
Write a 250-word Secondary 3 argumentative paragraph about whether students should use AI for homework. Use a balanced tone, include one benefit, one risk, and end with a clear personal judgement. Avoid technical jargon.

This is much better.

The prompt has fences.

It limits the AI’s movement.

The Fence Vocabulary Formula

A strong AI prompt usually contains several fences:

			
Task + Audience + Level + Format + Scope + Must Include + Must Avoid + Tone + Length + Verification

Example:

			
Write a Secondary 3 argumentative paragraph on whether students should use AI for homework. Keep it under 180 words. Use a balanced tone. Include one benefit, one risk and one final judgement. Avoid technical jargon. Make sure the argument is clear and suitable for an English essay.

This prompt is stronger because it tells AI what to do and what not to do.

Weak Prompt vs Fenced Prompt

Weak Prompt

Write about AI in school.

This is too vague.

AI must guess the purpose, level, length, tone and structure.

Fenced Prompt

			
Write a 200-word Secondary 3 expository paragraph explaining how AI can help students learn. Include two benefits and one caution. Use clear vocabulary, avoid technical jargon, and end with a sentence about responsible use.

This is stronger.

It has fences.

The AI knows:

audience: Secondary 3
task: expository paragraph
topic: AI and learning
length: 200 words
content: two benefits and one caution
tone: clear
avoid: technical jargon
ending: responsible use

This is English working like soft programming.

Why Fence Vocabulary Matters for Students

Fence Vocabulary teaches students that prompting is not casual chatting.

It is controlled instruction.

When students learn Fence Vocabulary, they become better at:

asking clear questions
controlling AI output
writing better essays
checking generated answers
avoiding vague responses
preserving their own voice
setting task boundaries
spotting missing information
improving weak paragraphs
using AI without becoming dependent

This is why prompt precision matters.

AI is not simply “understanding” the student like a human tutor sitting beside them.

It is converting natural English into a task pattern.

The clearer the instruction, the better the output.

Prompt example:
“Support this argument with two reasons and one example.”

Why it matters:
It prevents empty claims.

29. Challenge

Function: Tells AI to test or attack an idea.
Prompt example:
“Challenge this argument by giving one opposing view.”

Why it matters:
It helps students build stronger balanced essays.

30. Preserve

Function: Tells AI to protect what must not be changed.
Prompt example:
“Improve the grammar but preserve my original meaning and personal voice.”

Why it matters:
This is one of the most important AI-age prompting words. It stops AI from over-editing and replacing the student’s voice.

The Fence Vocabulary Formula

A strong AI prompt usually contains several fences:

			
Task + Audience + Level + Format + Scope + Must Include + Must Avoid + Tone + Length + Verification

Example:

			
Write a Secondary 3 argumentative paragraph on whether students should use AI for homework. Keep it under 180 words. Use a balanced tone. Include one benefit, one risk and one final judgement. Avoid technical jargon. Make sure the argument is clear and suitable for an English essay.

This prompt is stronger because it tells AI what to do and what not to do.

Weak Prompt vs Fenced Prompt

Weak Prompt

Write about AI in school.

This is too vague.

AI must guess the purpose, level, length, tone and structure.

Fenced Prompt

			
Write a 200-word Secondary 3 expository paragraph explaining how AI can help students learn. Include two benefits and one caution. Use clear vocabulary, avoid technical jargon, and end with a sentence about responsible use.

This is stronger.

It has fences.

The AI knows:

audience: Secondary 3
task: expository paragraph
topic: AI and learning
length: 200 words
content: two benefits and one caution
tone: clear
avoid: technical jargon
ending: responsible use

This is English working like soft programming.

Why Fence Vocabulary Matters for Students

Fence Vocabulary teaches students that prompting is not casual chatting.

It is controlled instruction.

When students learn Fence Vocabulary, they become better at:

This is why prompt precision matters.

AI is not simply “understanding” the student like a human tutor sitting beside them.

It is converting natural English into a task pattern.

The clearer the instruction, the better the output.

A Good Thought

AI makes English behave like programming in normal language.

That means students need to learn how to write prompts with fences.

A vague prompt gives AI too much freedom.

A precise prompt gives AI a controlled path.

Fence Vocabulary helps students build that path.

The most important lesson is this:

			
Prompting is not just asking.
Prompting is instructing.

And good instruction needs precision.

In the AI age, strong English is not only about writing beautiful sentences.

Strong English is also about giving clear commands, setting boundaries, checking output and preserving human meaning.

eduKateSG Learning System | Control Tower, Runtime, and Next Routes

This article is one node inside the wider eduKateSG Learning System.

At eduKateSG, we do not treat education as random tips, isolated tuition notes, or one-off exam hacks. We treat learning as a living runtime:

state -> diagnosis -> method -> practice -> correction -> repair -> transfer -> long-term growth

That is why each article is written to do more than answer one question. It should help the reader move into the next correct corridor inside the wider eduKateSG system: understand -> diagnose -> repair -> optimize -> transfer. Your uploaded spine clearly clusters around Education OS, Tuition OS, Civilisation OS, subject learning systems, runtime/control-tower pages, and real-world lattice connectors, so this footer compresses those routes into one reusable ending block.
