5.1 Start Here

A friend asks:

What is the best phone plan?

There is no single best plan for everyone.

  • A student who calls family abroad may need international minutes.
  • A delivery driver may need a lot of mobile data.
  • A parent may need a family plan.

The “best” choice depends on the person, the situation, the evidence, and the risks.

5.2 Why This Matters

You make decisions every day. Which class to take. Which job to apply for. How to spend time and money. AI can help you see options and compare them in English. But AI does not know your life. You do. Today you will learn a simple decision matrix and a human final decision rule.

5.3 Today You Will

By the end of this lesson, you will:

  1. Learn the parts of a decision matrix.
  2. Compare options using criteria, risks, and evidence.
  3. Practice English comparison phrases.
  4. Explain why AI should not make the final decision.
  5. Save: English AI Decision Toolkit/Lesson 3 - English Decision Matrix.md.

Theme: AI can help compare choices, but people make the final decision.

AI Focus: Decision matrix.

ESL Focus: Comparatives, modals, reasons, and risk language.

Content Objective: Students will compare two or three options using a decision matrix.

Language Objective: Students will use English comparison language:

Option A is cheaper than Option B.
Option B is more convenient.
I might choose...
I chose this because...
The risk is...

5.4 Core Idea

A decision matrix is a simple table for comparing choices. You pick the things that matter to you, called criteria. You add options, scores, and short evidence notes.

AI can help you find criteria you forgot or risks you did not see. AI should not choose for you.

ImportantHuman Final Decision Rule

AI can help you compare. You make the final decision.

NoteMethod Note

This activity adapts the decision matrix, also called a Pugh matrix, decision grid, or selection matrix. A decision matrix helps compare options against criteria and can use weights when some criteria matter more (American Society for Quality n.d.).

5.5 Key Vocabulary

Word Simple Meaning Example Sentence
option A choice Bus and train are two options.
compare Look at two or more things I compare the cost and time.
criteria The things that matter My criteria are cost and safety.
risk A possible problem The risk is arriving late.
evidence Information that supports an answer The price is evidence.
decision A choice after thinking My decision is to take the bus.
assumption Something I think is true but need to check My assumption is that the bus is on time.

5.6 Sentence Frames

For me, the most important criterion is __________.
Option A is cheaper than Option B.
Option B is more convenient than Option A.
I might choose __________ because __________.
Before I decide, I need to check __________.
AI helped me compare, but I chose __________.

5.7 Lesson Agenda

Time Activity Purpose
15 min Warm-up: What does “best” mean? Show that “best” depends on the person.
20 min Mini-lesson: decision matrix basics Learn options, criteria, scores, risks, and evidence.
25 min Guided practice: commute options Compare bus and train.
20 min Human decision rule discussion Separate AI suggestions from student decisions.
30 min Independent practice: my decision matrix Build a matrix for a safe decision.
10 min Pair speaking and exit ticket Explain the decision and what to verify.

5.8 Guided Practice

5.8.1 Warm-Up: What Does “Best” Mean?

Question:

What is the best phone plan?

Possible criteria:

  • cost
  • data
  • coverage
  • contract
  • family plan
  • international calls

Speaking frame:

For me, the most important criterion is __________ because __________.

5.8.2 Compare Two Commute Options

Criteria Importance 1-5 Bus Train Evidence / Notes
Cost 5 5 3 Bus is cheaper.
Time 4 2 5 Train is faster.
Convenience 3 3 4 Train has fewer stops.
Risk 4 3 4 Bus may be late.

Write three comparison sentences:

The bus is cheaper than the train.
The train is faster than the bus.
I might choose the train because time is important.

Do not make the final decision for me.
Use simple English.

5.13 Homework

Estimated time: 30-45 minutes.

Tasks:

  1. Finish Lesson 3 - English Decision Matrix.md.
  2. Add three decision words to Vocabulary Log.md.
  3. Check one fact in your matrix, such as price, time, or rule.
  4. Bring the matrix to Lesson 4 for revision.

What to save:

  • English AI Decision Toolkit/Lesson 3 - English Decision Matrix.md
  • updated Vocabulary Log.md

Privacy reminder: Do not use private financial, medical, legal, immigration, school, or work decisions for practice. Use safe everyday choices.

Optional extension: Open the Lessons 3-4 Decision Matrix Lab if your teacher asks.

TipOptional Colab Lab

This lab is optional. Use it only if your teacher asks or if you want extra practice. You do not need to complete the lab to finish your portfolio.

Open the Lessons 3-4 Decision Matrix Lab in Colab:

https://colab.research.google.com/github/zoni-group/E4A/blob/public-12db68dfaf5f/english-for-ai-course/interactives/class-02-decision-matrix-lab.ipynb

Use safe examples only. Do not enter private information.

The lab uses Colab AI automatically when it is available in the Colab runtime. If Colab AI is not available, the regular lab steps still work, and you can finish your portfolio without AI.

After any AI answer, say: “I checked the AI answer before I used it.”
