A delightful way to teach kids about computers | Linda Liukas


Code is the next universal language. In the seventies, it was punk music
that drove the whole generation. In the eighties, it was probably money. But for my generation of people, software is the interface
to our imagination and our world. And that means that we need a radically, radically
more diverse set of people to build those products, to not see computers as mechanical
and lonely and boring and magic, to see them as things
that they can tinker and turn around and twist,
and so forth. My personal journey into the world
of programming and technology started at the tender age of 14. I had this mad teenage crush
on an older man, and the older man in question
just happened to be the then Vice President
of the United States, Mr. Al Gore. And I did what every single
teenage girl would want to do. I wanted to somehow
express all of this love, so I built him a website, it’s over here. And in 2001, there was no Tumblr, there was no Facebook,
there was no Pinterest. So I needed to learn to code in order to express
all of this longing and loving. And that is how programming
started for me. It started as a means of self-expression. Just like when I was smaller,
I would use crayons and legos. And when I was older, I would use
guitar lessons and theater plays. But then, there were other things
to get excited about, like poetry and knitting socks and conjugating French irregular verbs and coming up with make-believe worlds and Bertrand Russell and his philosophy. And I started to be one of those people who felt that computers
are boring and technical and lonely. Here’s what I think today. Little girls don’t know that they
are not supposed to like computers. Little girls are amazing. They are really, really good
at concentrating on things and being exact and they ask
amazing questions like, “What?” and “Why?”
and “How?” and “What if?” And they don’t know that they
are not supposed to like computers. It’s the parents who do. It’s us parents who feel like computer science
is this esoteric, weird science discipline that only belongs to the mystery makers. That it’s almost as far removed
from everyday life as, say, nuclear physics. And they are partly right about that. There’s a lot of syntax
and controls and data structures and algorithms and practices, protocols and paradigms in programming. And we as a community,
we’ve made computers smaller and smaller. We’ve built layers and layers
of abstraction on top of each other between the man and the machine to the point that we no longer
have any idea how computers work or how to talk to them. And we do teach our kids
how the human body works, we teach them how
the combustion engine functions and we even tell them
that if you want to really be an astronaut you can become one. But when the kid comes to us and asks, “So, what is a bubble sort algorithm?” Or, “How does the computer know
what happens when I press ‘play,’ how does it know which video to show?” Or, “Linda, is Internet a place?” We adults, we grow oddly silent. “It’s magic,” some of us say. “It’s too complicated,” the others say. Well, it’s neither. It’s not magic and it’s not complicated. It all just happened
really, really, really fast. Computer scientists built
these amazing, beautiful machines, but they made them
very, very foreign to us, and also the language we speak
to the computers so that we don’t know
how to speak to the computers anymore without our fancy user interfaces. And that’s why no one recognized that when I was conjugating
French irregular verbs, I was actually practicing
my pattern recognition skills. And when I was excited about knitting, I actually was following
a sequence of symbolic commands that included loops inside of them. And that Bertrand Russell’s lifelong quest to find an exact language
between English and mathematics found its home inside of a computer. I was a programmer, but no one knew it. The kids of today, they tap, swipe
and pinch their way through the world. But unless we give them tools
to build with computers, we are raising only consumers
instead of creators. This whole quest
led me to this little girl. Her name is Ruby, she is six years old. She is completely fearless,
imaginative and a little bit bossy. And every time
I would run into a problem in trying to teach
myself programming like, “What is object-oriented design
or what is garbage collection?”, I would try to imagine how a six-year-old
little girl would explain the problem. And I wrote a book about her
and I illustrated it and the things
Ruby taught me go like this. Ruby taught me that you’re
not supposed to be afraid of the bugs under your bed. And even the biggest of the problems are a group of tiny problems
stuck together. And Ruby also introduced
me to her friends, the colorful side of the Internet culture. She has friends like the Snow Leopard, who is beautiful but doesn’t want
to play with the other kids. And she has friends like the green robots
that are really friendly but super messy. And she has friends like Linux the penguin who’s really ruthlessly efficient,
but somewhat hard to understand. And idealistic foxes, and so on. In Ruby’s world, you learn
technology through play. And, for instance, computers
are really good at repeating stuff, so the way Ruby would teach
loops goes like this. This is Ruby’s favorite dance move,
it goes, “Clap, clap, stomp, stomp clap, clap and jump.” And you learn counter loops
by repeating that four times. And you learn while loops
by repeating that sequence while I’m standing on one leg. And you learn until loops
by repeating that sequence until mom gets really mad. (Laughter) And most of all, you learn
that there are no ready answers. When coming up with the curriculum
for Ruby’s world, I needed to really ask the kids
how they see the world and what kind of questions they have and I would organize
play testing sessions. I would start by showing the kids
these four pictures. I would show them a picture of a car, a grocery store, a dog and a toilet. And I would ask, “Which one of these
do you think is a computer?” And the kids would be
very conservative and go, “None of these is a computer. I know what a computer is: it’s that glowing box in front of which mom or dad
spends way too much time.” But then we would talk and we would discover
that actually, a car is a computer, it has a navigation system inside of it. And a dog — a dog
might not be a computer, but it has a collar and the collar might have
a computer inside of it. And grocery stores, they have
so many different kinds of computers, like the cashier system
and the burglar alarms. And kids, you know what? In Japan, toilets are computers and there’s even hackers who hack them. (Laughter) And we go further and I give them these little stickers
with an on/off button on them. And I tell the kids,
“Today you have this magic ability to make anything in this room
into a computer.” And again, the kids go, “Sounds really hard,
I don’t know the right answer for this.” But I tell them, “Don’t worry, your parents don’t know
the right answer, either. They’ve just started
to hear about this thing called The Internet of Things. But you kids,
you are going to be the ones who are really going to live up in a world
where everything is a computer.” And then I had this little girl
who came to me and took a bicycle lamp and she said, “This bicycle lamp,
if it were a computer, it would change colors.” And I said, “That’s a really good idea,
what else could it do?” And she thinks and she thinks, and she goes, “If this bicycle lamp
were a computer, we could go on a biking trip
with my father and we would sleep in a tent and this biking lamp
could also be a movie projector.” And that’s the moment I’m looking for, the moment when the kid realizes that the world
is definitely not ready yet, that a really awesome way
of making the world more ready is by building technology and that each one of us
can be a part of that change. Final story, we also built a computer. And we got to know the bossy CPU
and the helpful RAM and ROM that help it remember things. And after we’ve assembled
our computer together, we also design an application for it. And my favorite story is this little boy, he’s six years old and his favorite thing in the world
is to be an astronaut. And the boy, he has
these huge headphones on and he’s completely immersed
in his tiny paper computer because you see, he’s built his own intergalactic planetary
navigation application. And his father, the lone astronaut
in the Martian orbit, is on the other side of the room and the boy’s important mission is to bring the father
safely back to earth. And these kids are going to have
a profoundly different view of the world and the way we build it with technology. Finally, the more approachable,
the more inclusive, and the more diverse
we make the world of technology, the more colorful and better
the world will look like. So, imagine with me, for a moment, a world where the stories we tell about how things get made
don’t only include the twentysomething-year-old
Silicon Valley boys, but also Kenyan schoolgirls
and Norwegian librarians. Imagine a world where
the little Ada Lovelaces of tomorrow, who live in a permanent
reality of 1s and 0s, they grow up to be very optimistic
and brave about technology. They embrace the powers
and the opportunities and the limitations of the world. A world of technology
that is wonderful, whimsical and a tiny bit weird. When I was a girl, I wanted to be a storyteller. I loved make-believe worlds and my favorite thing to do was to wake up in the mornings
in Moominvalley. In the afternoons,
I would roam around the Tatooines. And in the evenings,
I would go to sleep in Narnia. And programming turned out
to be the perfect profession for me. I still create worlds. Instead of stories, I do them with code. Programming gives me this amazing power to build my whole little universe with its own rules
and paradigms and practices. Create something out of nothing
with the pure power of logic. Thank you. (Applause)

  1. Funny how chemistry takes precedence over basic computing.
    "How do nuclear reactors work?"
    "I dunno, let me ask this little magic box."

  2. Right now I can't tell you how much I'm in love with Linda's energy, ethusiasm, intelligence, her voice, her constant smiling and her will to do good in such a smart and beautiful way.

  3. There's a Programming class available in my college that fulfills the Analytical Thought requirement. I'm definitely going to sign up for it!

  4. Aw this makes me look forward to starting a coding unit in a week. I always loved the idea of creating basically anything on a computer through coding but I was put off by students who said everyone hates the coding unit.
    This restored my faith eheh

  5. A teacher who doesn't rely on rote memorization of facts that could be looked up in seconds, and instead actually tries to engage the students? What is this heresy?
    I wish her well.

  6. Amazing presentation. So much energy and I completely agree. People need to embrace the technology. Kids need to learn programming in schools because whether they like it or not, it is the future. And also there is something about programming that is special. Not many things can give you the satisfaction of creating something that is actually useful, fun or just pretty. I'm not saying it is for everyone and everyone will enjoy it. But I do believe a lot more people would find a passion if they tried it.

    Strangely enough I love programming and filmmaking. Two things that may seem very different. But maybe they’re not. 🙂

  7. She is very bright and exciting! And I loved her speech. I think I should try to remember how I saw the world when I was young:)

  8. this talk was full of so much passion that it actually made me go to my computet practice some coding. beautiful presentation

  9. This is great – love her energy and, more importantly, the power she's bringing to young lives and the future she's building for us all.

  10. No standing ovation? That was one of the most enthusiastic, exciting and simple talks about coding, for future generations, I have ever heard.

  11. "Create something out of nothing with the pure power of logic". Wow… that's exactly how I feel about software development. What a great talk.

  12. This video has a focus on getting girls into CS. It's true, we need more women in CS, but we also need more men in CS. The number of CS jobs being offered is skyrocketing and there's simply not enough people to fill those positions. Beyond that, the principle that the average person should know more about CS is a solid one. All of technology was created with some sort of inherent logic.

  13. am i the only one that thinks that she belongs in a mental institution and not on a stage? not because her talk is bad but rather she brings up stuff that is absolutely ridiculous

  14. This world she is describing will only happen if we don't give way to the likes of Apple, Microsoft (especially in the form of Phone and Games For Windows), Nintendo and many others.

    DRM is defective by design

  15. She's so cute! Her enthusiasm and smile make me really happy. I guess happiness is contagious. You can really tell she's passionate about coding. I wish her well!

  16. Linda has given me a new perspective on coding. I've always been a networking guy and used to look at coding as rather monotonous. That's changed now.

  17. Very interesting talk. And also, congrats for being able to turn a subject that can be hard at times into a bunch of cute characters and stories that are easily understandable, not only by kids, but by anyone.

    I loved the "build your own computer" part.

  18. computers are only as complicated as you want them to be! (so never let them intimidate you!) Just swim in the shallow end of the pool and don't be intimidated by what you see in the deep end, because you only have to go there if and when you want. Likewise with programming… yes it can get very complicated at the deep end, but writing simple text adventure games or drawing images in languages like Basic and Logo and so on is very simple – I encourage kids to start programming as soon as they can, but it's important to help ensure they don't get overwhelmed

  19. Great talk. I wish I was taught coding when I was at school. I'm currently teaching myself, doing bits here and there. Coding and programming is the backbone for many jobs nowadays in such an age where our lives revolve around tech.

  20. She loves what she does. That's what I thought throughout the entire talk. She's lucky to have found a way to do what she loves for a living. And her students are lucky to have found a teacher who teaches with such passion. The perfect classroom!

  21. I can't see how any of what she's talking about is helpful…Programming should be taught at an age appropriate time, like 8th grade. If kids can't do algebra and arithmetic, how are they going to learn about the complex logic of computers…? The material she presented about looping concepts is better taught in gym class and learning sports. American schools need to remove the politics and testing and let teachers work. A lesson plan from the 1970's is probably better than a modern one. In those days we had several aids in the class and parents with the time to help. Now we want it all for 25 students per class and a single over worked teacher. The teachers just complain about salary….it's crazy.
