Lesson video

Hello, everyone.

Welcome to today's lesson.

My name is Mrs. Jenkins.

Today's lesson is called "What Is Artificial Intelligence?

" And it is taken from the unit The Digital Discovery Squad.

Let's get started.

In today's lesson, our learning outcome is: I can explain what artificial intelligence is and what it is not.

In our lesson today, we have three keywords.

These words will appear throughout the lesson, so it's really important we know what they mean before we get started.

The words are artificial intelligence, or AI; human; and instructions.

So, artificial intelligence, or AI, is computer technology that gives answers by following instructions.

A human is a person who can think, feel, and understand.

Instructions are clear steps that tell someone or something what to do.

So, those three words are artificial intelligence, or AI; human; and instructions.

These words will appear throughout the lesson today, so it's really important we keep an eye out for them.

In our lesson today, "What is artificial intelligence?

" we have two learning cycles: identify examples of AI; and explain how AI follows instructions.

We're going to begin with identify examples of AI.

A computer can follow fixed rules.

For example, a calculator always adds numbers using the same steps.

Some computer systems do more than just follow these fixed steps.

They look for patterns in data to generate answers.

For example, a simple spell-check works by checking if a word is included in a list.

Predictive text, on the other hand, analyzes the whole sentence and generates likely words based on the context.

Okay, let's have a check.

Which of these examples always follows the same steps?

A: a calculator adding five add three; B: a video platform suggesting what to watch; or C: a voice-assistant answering questions.

What do you think?

Have a go.

How did you get on?

I asked, which of these examples always follows the same steps?

A: a calculator adding five add three; B: a video platform suggesting what to watch; or C: a voice assistant answering questions.

The answer is, a calculator adding five add three will always follow the same steps.

Great job, everyone.

Artificial intelligence, AI, is a type of computer system that is trained using examples.

Humans provide these examples, so the system can learn patterns.

For example, a human may provide lots of example images of labeled fruit.

So, here we've got three different types of apple, and we've got lots of different sizes and shapes of orange.

If the system is then given a different image of a piece of fruit, it can generate a suggestion for what the fruit is by comparing patterns in the data.

So, here you can see this is an apple.

These systems still follow rules written by humans.

Okay, let's have a little check.

Which of these is most likely to be using AI?

A: a calculator; B: a search-engine suggesting results; C: a traffic light; or D: a printed book.

What do you think?

Have a go.

How did you get on?

I asked you, which of these is most likely to be using AI?

A: a calculator; B: a search engine suggesting results; C: a traffic light; or D: a printed book.

The answer is B.

A search engine suggesting results is the most likely to be using AI.

Great job, everyone.

An AI system generates answers, but it does not understand them.

It does not think or feel like a human.

Humans understand meaning, but AI systems just compare patterns and follow rules.

Sam says, "I understand what this means.

" That's right, Sam.

You understand because you are a human.

If a computer gives suggestions, answers questions, recognizes speech, it might be using AI.

If it only follows simple fixed steps, it is not AI.

Okay, we are going to move on to task A.

For part one, I would like you to decide whether each example uses AI, so follows patterns.

So, we have A: a calculator; B: a voice assistant; C: traffic lights; D: predictive text; E: face unlock; and F: a paper dictionary.

Have a go.

How did you get on?

I just asked you to decide whether each example uses AI, so if it follows patterns.

A: calculator; B: voice assistant; C: traffic lights; D: predictive text; E: face unlock; and F: paper dictionary.

So, a voice assistant, predictive text, and face-unlock use AI.

Calculator, traffic lights, and a paper dictionary do not.

Going to move on to part two of our first task now.

I would like you to choose one example of an AI tool and explain what patterns it compares.

So, we have A: voice assistant; B: predictive text; and C: face unlock.

Have a go.

How did you get on?

I asked you to choose one example of an AI tool and explain what patterns it compares.

So, we had a voice assistant, predictive text, and face unlock.

Aisha says, "A voice assistant compares sounds patterns in the speech with stored data to match the words.

" Great job, Aisha.

Andeep says, "Predictive text compares the words in the sentence with stored word patterns to suggest a likely word.

" That's right, Andeep.

Well done.

And Jacob says, "Face unlock compares patterns in a face with stored patterns to check for a match.

" Great job, Jacob.

Well done, and well done, all of you.

Let's move on to learning cycle two now: explain how AI follows instructions.

A system follows instructions written by a human.

Humans decide what an AI system is designed to do.

An AI system cannot decide its own goals.

" Alex says, "If I design it to recognize faces, that's all it will be able to do.

" That's right, Alex.

Well done.

For example, a voice assistant is designed to detect your words, match them to patterns, and follow instructions to generate an answer.

Okay, let's have a little check now.

What does an AI system follow to give an answer?

A: its own ideas and feelings; B: instructions written by a human; or C: random guesses and predictions.

What do you think?

Have a go.

How did you get on?

I asked you, what does an AI system follow to give an answer?

A: its own ideas and feelings; B: instructions written by a human; C: random guesses and predictions.

The answer is B.

An AI system follows instructions written by a human to be able to give an answer.

Great job, everyone.

Instructions tell AI systems what data to use, what patterns to compare, and what answer to generate.

AI systems follow these instructions step by step.

Okay, let's have another check-in here.

I would like you to fill in the missing words.

AI systems follow, mm, written by, mm, to give answers.

What do you think?

Have a go.

How did you get on?

I asked you to fill in the missing words.

AI systems follow, mm, written by, mm, to give answers.

So, our answers are instructions and humans.

AI systems follow instructions written by humans to give answers.

Great job, everyone.

Humans understand meaning and make their own choices.

This is something that AI systems cannot do, even if it sometimes looks like they do.

Okay, we're going to move on to task B now.

I would like you to explain why Jacob is incorrect.

Jacob says, "My AI tool answers questions because it understands them.

" So, for the first part, circle the part of Jacob's sentence that is incorrect.

For the second, write a short explanation explaining what AI tools actually do.

Have a go.

How did you get on?

I asked you to explain why Jacob is incorrect.

Jacob said, "My AI tool answers questions because it understands them.

" So, number one: we'll circle the part of Jacob's sentence that is incorrect.

Number two: write a short explanation explaining what AI tools actually do.

So, the part of Jacob's sentence that is incorrect is "because it understands them.

" Laura has given us an explanation.

"AI tools do not understand questions.

AI tools follow instructions written by humans and compare patterns in data.

Then they generate an answer based on these instructions.

" Thank you, Laura, that's a fantastic answer, and well done, all of you.

Your digital discovery squad member has earned their third badge.

You now know what artificial intelligence, or AI, is and what it is not.

Add your AI Explorer badge and your character's rule to your log book.

Well done, everyone.

You have worked extremely hard in today's lesson.

Let's summarize what we have learned.

Artificial intelligence, AI, compares patterns in data to give answers or suggestions.

AI tools follow instructions written by humans.

Not all technology is AI; some systems follow fixed rules.

AI tools do not think or understand like a human.

Great job, everyone.

You've worked really hard today.

I hope to learn with you again soon.
