IGCSE Computer Science – Section 6: Automated and Emerging Technologies

4 minutes: Arrival & Settle

Getting Ready

Welcome to today's lesson!

Please complete the following as you settle in:

• Take your seat quietly

• Open your exercise book or get loose paper ready

• Write today's date

Write the title: "Introduction to Artificial Intelligence (AI)"

Retrieval questions will appear on the board in a moment.

4 minutes: Silent Retrieval

Retrieval Practice – Automation & Robotics

Answer these questions SILENTLY on scrap paper:

1

What is the role of a sensor in an automated system?

2

Give one advantage of using robots in industry.

3

What component controls the actuators in a robotic system?

4

True or False: Robots always make independent decisions.

Write your answers independently. No talking during this time.

Retrieval Answers

Check Your Responses

Question 1

A sensor detects changes in the environment (temperature, light, pressure, etc.) and sends data to the microprocessor.

Question 2

Robots can work 24/7 without breaks, increase speed and precision, or work in dangerous environments.

Question 3

The microprocessor (or control unit) processes sensor data and sends signals to actuators.

Question 4

False. Many robots follow fixed programs without making independent decisions.

Learning Objectives

What We'll Learn Today

By the end of this lesson, you will be able to:

01

Define artificial intelligence in your own words

02

Name at least two real-world examples of AI systems

03

Explain how AI differs from basic automated systems

5 minutes: Starter Activity

Odd One Out Challenge

Work in pairs for a class competition! For each set below, decide which is the odd one out and explain why. The first pair to correctly identify the odd one out and provide a strong justification for each set earns 5 points for their team!

Set 1

• Alexa

• Siri

• Washing Machine

Set 2

• Robot Vacuum

• Electric Fan

• Thermostat

Set 3

• Tesla Autopilot

• Human Driver

• Car Dashboard

Write your answers and justifications on your worksheet. Remember, clear explanations on how each item relates to learning, adapting, or making decisions will earn you those valuable points for the class competition!

Starter Discussion

What Did You Notice?

Key Ideas From Your Answers

Some systems just follow fixed programs:

• Washing machines run pre-set cycles

• Electric fans turn on/off at set speeds

• Dashboards display information only

Other systems learn, adapt, or make decisions:

• Alexa and Siri recognise your voice better over time

• Robot vacuums learn room layouts

• Tesla Autopilot adjusts to traffic conditions

10 minutes: Teacher Input

What is Artificial Intelligence?

"Artificial intelligence is when a computer system can do tasks that usually need human intelligence, such as learning, making decisions or recognising patterns."

Think of AI like a digital apprentice that watches, learns, and improves at its job over time.

Key characteristics of AI systems:

Sensing

Uses cameras, microphones, or sensors to gather data from the environment

Deciding

Makes choices based on data and patterns it has learned

Learning

Improves performance over time through experience

Three Types of Artificial Intelligence

Narrow AI (Weak AI)

Very good at ONE specific task. This is the only type that exists today. Examples: Siri, spam filters, chatbots, recommendation systems, facial recognition.

General AI

As smart as a human across MANY tasks. Could learn and apply knowledge to different problems. Does not exist yet – still in research.

Strong AI (Super AI)

More intelligent than humans in MANY areas. Would surpass human capabilities. Currently science fiction – think of films like Ex Machina or Her.

Real-World Examples of Narrow AI

Voice Assistants

Siri, Alexa, Google Assistant use speech recognition and natural language processing to understand commands and improve over time.

Recommendation Systems

Netflix, Spotify, and YouTube analyse your viewing habits to suggest content you might enjoy.

Spam Filters

Email services learn to identify spam patterns and block unwanted messages more effectively over time.

Facial Recognition

Used in phone unlocking, security systems, and social media tagging – learns to identify faces accurately.

12 minutes: Collaborative Activity

Race to be the AI Experts! AI or Not? You Decide

Work in pairs or groups of three. You are competing against other teams! Use your worksheet to decide whether each item uses AI, and justify your answer briefly.

Points System: Earn 1 point for each correct answer. An additional 1 bonus point will be awarded for the best justification on each item (decided by the instructor). Track your team's score!

Ask yourself these questions:

Does it sense the environment?

Does it make decisions on its own?

Does it learn or adapt over time?

Time is ticking! You have 8–10 minutes to complete this challenge. Word bank on board: sensor, decision, learn, adapt, program.

AI or Not? – The Items

Examine each of these systems and determine whether they use AI:

• Smart fridge

• Thermostat

• Chatbot

• Washing machine

• Tesla Autopilot

• Microwave

• OCR scanner

• Alexa

• Lift/elevator

• Human driver

Complete the activity on your worksheet, then we'll review answers together.

AI or Not? – Sample Answers

✓ AI Systems

Chatbot – learns from conversations, makes responses

Tesla Autopilot – senses traffic, makes driving decisions, adapts

Alexa – voice recognition improves, learns preferences

OCR scanner – learns to recognise text patterns

Smart fridge (some models) – tracks food, suggests recipes

✗ Not AI Systems

Washing machine – follows fixed program cycles

Microwave – timer and heating only, no learning

Basic thermostat – turns on/off at set temperature

Lift/elevator – pre-programmed routes

Human driver – uses natural intelligence!

Challenge Mode: Concept Sorting

AI Characteristics Sorting Challenge

Pairs, prepare for battle! Your mission: On your worksheet, correctly categorize each item as quickly as possible. Every correct placement earns 2 points, and a bonus for the fastest team! We'll track your scores on a live leaderboard to see which team reigns supreme in AI knowledge!

Senses Environment

Gathers data from the world

Moves or Acts

Takes physical action

Learns/Adapts/Decides

Makes choices and improves

Beat the Clock! These are your items to sort: Microphone • Wheel • Voice Recognition • Camera • Chatbot • Decision Algorithm • Motor • Radar

Hint for victory: Microphone → Senses environment (detects sound). Get it right for those crucial 2 points!

Concept Sorting – Answers

Senses Environment

Microphone – detects sound

Camera – captures images

Radar – detects objects and distance

Moves or Acts

Wheel – provides movement

Motor – creates physical motion

Learns/Adapts/Decides

Voice Recognition – learns accents

Chatbot – improves responses

Decision Algorithm – chooses actions

Higher ability challenge: Can you add one extra example to each category from your own knowledge?

AI vs. Simple Automation – Key Differences

Simple Automation

Follows fixed instructions

Same response every time

No improvement

Example: Washing machine, microwave

Artificial Intelligence

Makes decisions based on data

Adapts to new situations

Improves with experience

Example: Siri, self-driving car

Remember: Not everything with a computer is AI. True AI learns, adapts, and makes decisions – automation simply follows pre-programmed rules.

Common Misconceptions About AI

1

❌ "Anything with a computer is AI"

Truth: Most computers just follow fixed programs. AI must learn, adapt, or make independent decisions.

2

❌ "All robots are intelligent"

Truth: Many robots simply follow pre-programmed instructions without any learning capability. AI robots can adapt and learn.

3

❌ "AI always looks like a human robot"

Truth: Most AI is invisible software running in apps, websites, and devices. You interact with AI daily without seeing a physical robot.
