This week, the coolest history lesson in history. The smallest car

:00:09.:00:16.

race in the world. And we are with the Doctor as something goes bump in

:00:17.:00:19.

the night. School, it has changed a lot since I

:00:20.:00:50.

went through the mangle all those years ago. Many. Years ago. School

:00:51.:01:00.

buildings may look the same but technology has been infusing

:01:01.:01:04.

education for some time. We have smart whiteboards, increasing use of

:01:05.:01:09.

instead of textbooks, but also there instead of textbooks, but also there

:01:10.:01:13.

are some systems which mean the way kids learn and are taught is

:01:14.:01:19.

changing completely. It seems many tech giants want to become part of

:01:20.:01:23.

education. After all, an early introduction to their brands may one

:01:24.:01:26.

day at up to a greater number of users. Microsoft this week launched

:01:27.:01:32.

its education offering which includes a new version of Windows

:01:33.:01:36.

called Windows S, a budget surplus pro in various colours and some

:01:37.:01:42.

treats to its office applications. Apple's teaching tool Classroom had

:01:43.:01:46.

a face-lift last month and now offers mortals the teachers, but

:01:47.:01:50.

before both of these came Google classroom. Today I am finding out

:01:51.:01:56.

more about it from the director of learning at training secondary

:01:57.:01:59.

online system the past 18 months to online system the past 18 months to

:02:00.:02:02.

teach and monitor the student' progress. Today I am learning about

:02:03.:02:09.

the Galapagos Islands and the lesson Chris has constructed

:02:10.:02:11.

looks more engaging than my old looks more engaging than my old

:02:12.:02:15.

textbooks. But tech can do a lot more than provide media rich lesson

:02:16.:02:19.

plans. We are able to personalise what we do more than before. We can

:02:20.:02:24.

take them to different resources available on the system. Every

:02:25.:02:29.

student's learning journey will be different. Taking teaching online

:02:30.:02:32.

means teachers have more access to children's individual learning data

:02:33.:02:38.

and even their thought processes. This browser extension lets the

:02:39.:02:42.

teacher watch how an essay was written and refined. If I have a

:02:43.:02:49.

student who in preparation for exams is not constructing paragraphs

:02:50.:02:52.

correctly I can say let's look at how you constructed your particular

:02:53.:02:57.

paragraph. What did you do? Where did you develop it? What can we do

:02:58.:03:02.

differently? If it is maybe two or three paragraphs and they spend so

:03:03.:03:05.

long on the first one, I can also say this is how long you spend on

:03:06.:03:09.

the first one, half an hour, Yuri spent part five minutes on the

:03:10.:03:13.

second and third. The kids also seem to like it. Lots of time we can

:03:14.:03:19.

still work at home and teachers can still be there on our thing and see

:03:20.:03:22.

how much we have done. If the teacher doesn't believe you have

:03:23.:03:27.

spent the required amount of time on the home work, you can say I did,

:03:28.:03:31.

look at the edit history. It is so much quicker, handing in work, you

:03:32.:03:39.

can hand it in and within 20 minutes have it back. Using online tools and

:03:40.:03:43.

data is one way to enhance learning in schools. But Lara Lewington has

:03:44.:03:49.

been looking at other tech which promises to change how children

:03:50.:03:56.

learn completely. VR, robots, holograms, it was not

:03:57.:04:01.

like this in my day! At the Best Can extrication show, we saw some of the

:04:02.:04:08.

most cutting edge ideas heading to the classroom soon. Over the last

:04:09.:04:12.

few months I have seen quite a few devices that bring together the idea

:04:13.:04:16.

of kids coding and toys, aiming to make it more fun, but good old Lego

:04:17.:04:21.

have gone a step further. They are trying to recreate real life

:04:22.:04:24.

situations where robots would be used so that children can find

:04:25.:04:28.

problems and then find a solution. The mission we have here is for a

:04:29.:04:33.

space robot which needs to move around the space base, collecting

:04:34.:04:36.

these pieces together and taking them back to one place. Obviously,

:04:37.:04:42.

the coding should do that bit. Using the Dragon drop box to create

:04:43.:04:49.

sequences that carry out actions as part of the learning process, as

:04:50.:04:52.

science is being taught at the same time. But brick so's vision of what

:04:53.:04:59.

can be learned is quite different. This is a way to bring your existing

:05:00.:05:04.

Lego set to life. It has some LED lights, a sense that, and these

:05:05.:05:10.

locks conduct electricity! From there you can create what ever

:05:11.:05:13.

spreading, moving, lighting functions create your fancy. But

:05:14.:05:17.

this use of technology is not just about teaching ICT, this adaptive

:05:18.:05:24.

learning is about employing new methods of teaching traditional

:05:25.:05:27.

classes. The teacher guides the experience but the student... This

:05:28.:05:34.

is Google Expedition. Jenny is going to play the part of a teacher, she

:05:35.:05:38.

will talk through what we are looking at in the goggles. It

:05:39.:05:43.

represents all of you... The pictures are amazing. Looking at the

:05:44.:05:49.

difference between the healthy and smoker's lungs I think we'll stick

:05:50.:05:53.

with them. The idea of an image in your mind is easier to maintain than

:05:54.:05:57.

someone talking. My issue is actually with the idea of the

:05:58.:06:00.

goggles. They are fine for a couple of minutes but then I feel the urge

:06:01.:06:04.

to take them off, I can't imagine wearing them for a full lesson. Many

:06:05.:06:11.

of these ideas will be picked up by individual schools, but although the

:06:12.:06:15.

ideas and devices are out there the challenge comes in making them

:06:16.:06:20.

available to the masses. That is something that one not-for-profit

:06:21.:06:23.

Finland, a country considered to Finland, a country considered to

:06:24.:06:25.

have one of the worlds best education systems, is to overcome. I

:06:26.:06:31.

would say education is when of the few big industries that is still

:06:32.:06:36.

waiting to be disrupted. One of the biggest challenges in the system is

:06:37.:06:39.

that it is based on the ideas of the industrial world. It is teaching

:06:40.:06:45.

everyone to be the same. In tomorrow's world it is crucial to be

:06:46.:06:50.

individual. One idea turns things on its head. Focusing not simply on new

:06:51.:06:55.

ways of teaching but firstly analysing how we learn. I am on my

:06:56.:07:01.

way to maths class which should cause me some concern because I'm

:07:02.:07:04.

not sure I remember that much from school. But with this class

:07:05.:07:08.

everybody is having their own private lesson. The teacher does not

:07:09.:07:17.

stand up and project their voice to start the session, the kids take

:07:18.:07:21.

their places at computers where AI will take them through the lesson.

:07:22.:07:25.

This artificial intelligence system aims to teach each pupil at their

:07:26.:07:30.

own pace and in the way that suits them best. Constantly gets to know

:07:31.:07:35.

them better and track in their process. The purpose of this machine

:07:36.:07:39.

is to learn how your brain learns and then utilise that data, is

:07:40.:07:44.

constantly adapts to provide them with a top tier education at every

:07:45.:07:47.

moment. And then take that data and offer it to the teacher in reason

:07:48.:07:52.

real-time. Here the student generates the data. It is provided

:07:53.:07:56.

in real-time to teachers, they can intervene when necessary and they

:07:57.:08:00.

can spend more time on human interaction with the student, the

:08:01.:08:06.

pastoral care they need to provide. Teachers can share their content

:08:07.:08:10.

around the world with other people using the system. Any given subject

:08:11.:08:15.

could have numerous options machine can select from based on the

:08:16.:08:20.

student's focus and learning levels. And if they choose to manually

:08:21.:08:24.

switch it tracks and considers their preferences to. What you feel are

:08:25.:08:31.

the chances? If you're not to share on question, it is easier to have a

:08:32.:08:34.

human explain it to you. But the commute pewter makes it as easy as

:08:35.:08:40.

possible. While I can see the benefits, there is one

:08:41.:08:41.

on my mind. That is the amount of on my mind. That is the amount of

:08:42.:08:49.

screen time. We have had plenty of teachers not just parents, saying do

:08:50.:08:53.

we want them staring at the screen? The answer is not binary. That is

:08:54.:08:57.

important. We don't think teachers should be replaced, we need more

:08:58.:09:01.

teachers, but we think they should spend their time teaching inspiring,

:09:02.:09:06.

imparting knowledge of a stubbed it they really understand. There is no

:09:07.:09:09.

shortage of ideas yet naturally putting them to the test requires

:09:10.:09:12.

people willing to take the chance on them. Clearly the idea of technology

:09:13.:09:18.

giving an overhaul to how we educate our kids does not seem far away.

:09:19.:09:28.

Welcome to the week in Tech. It was the week that Elon musk talked about

:09:29.:09:36.

tunnels again. He has proposed underground network where your car

:09:37.:09:40.

is shuttled from A to B on an electric skate that could go up to

:09:41.:09:45.

130 mph. The name of it, the boring company. It was also the users of

:09:46.:09:52.

what set were asked what is happening after the service went

:09:53.:09:54.

down for several hours around the world. The bank accounts of O2

:09:55.:09:59.

customers in Germany were drained after the S S seven mobile telecoms

:10:00.:10:06.

system was hacked. We covered their vulnerability last year. In Sweden

:10:07.:10:10.

and the world's fastest camera has been developed. It can capture 5

:10:11.:10:17.

trillion images per second. Others, typically get 100,000. Instead of

:10:18.:10:25.

captured an image is one it captures several at once and pieces them

:10:26.:10:29.

together into video. It can be used to video things like brain activity

:10:30.:10:35.

and chemical reactions. Finally, innovative help robots run better,

:10:36.:10:40.

this ostrich like bot can sprint up to ten mph and can self balance

:10:41.:10:46.

without the need for sensors or computer processing. A single motor

:10:47.:10:51.

drives its legs forwards in an elliptical motion in jet and more

:10:52.:10:54.

power when it feels resistance. It has a mind of its own! Everyone down

:10:55.:11:05.

to the pub for a swift half, a game of bar billiards and a battle with

:11:06.:11:13.

giant bugs. The perfect evening. There are a couple of things you

:11:14.:11:17.

always find in a British pub. Number one, pints of beer. In some drinking

:11:18.:11:23.

shops there are distractions like darts. And of course virtual reality

:11:24.:11:31.

find your pint? The big problem for find your pint? The big problem for

:11:32.:11:38.

most people with virtual reality is space. You don't have the space in a

:11:39.:11:42.

normal sized living room to play the ER games properly. The headsets have

:11:43.:11:48.

cables attached which you can trip over and then you have furniture and

:11:49.:11:53.

walls to bang into. That is where pubs come in. Pubs are generally

:11:54.:11:57.

bigger than the house you live in so there is no problem with space. And

:11:58.:12:04.

they afford you the opportunity for truly social virtual reality

:12:05.:12:06.

experience is because people can see what you are doing. So the wars in

:12:07.:12:14.

here are green. That means the spectators watching me play can see

:12:15.:12:18.

the environment I am in and if I back myself up to them I feel they

:12:19.:12:24.

are soft. They are padded, so payers cannot injure themselves if they get

:12:25.:12:30.

too energetic and throw themselves around. It is like a soft play area

:12:31.:12:36.

for adults. The combination of public house and virtual reality is

:12:37.:12:40.

the brainchild of these guys, they have used their backgrounds in

:12:41.:12:43.

satellite technology, IT and engineering to create this setup.

:12:44.:12:48.

What made you think that VR and pubs when together? We wanted to do a VR

:12:49.:12:57.

arcade, but finding arcades have a stale and outdated image. So we were

:12:58.:12:59.

looking for a good venue to do looking for a good venue to do

:13:00.:13:03.

virtual reality in public. When you are involved with alcohol there is

:13:04.:13:07.

always a degree of risk to the gear and the equipment. So we have had to

:13:08.:13:13.

rig up our nurses so that if people fall over they do not damage

:13:14.:13:18.

themselves, the harness also protect the headsets so they don't fall on

:13:19.:13:24.

the ground. Enough talk. Time to try out the specially designed VR rake.

:13:25.:13:31.

We have it plugged into this seat belt arrester system. It will catch

:13:32.:13:35.

you if you fall. In order to make it safe, it is crucial that cables are

:13:36.:13:39.

kept out of the way. I have a harness I have to put on. It goes on

:13:40.:13:45.

there. And then we put this in at the back. And now, no matter how

:13:46.:13:49.

much you turn around, the cable will not get caught. An ingenious

:13:50.:14:00.

solution to the cable problem. Now I've played tonnes of games in VR

:14:01.:14:05.

before, and as always I am immediately transported from the

:14:06.:14:10.

space I was in into this sewer. Zombies coming from pretty much

:14:11.:14:14.

every direction. Gunn shot reload, reload! You don't really notice the

:14:15.:14:24.

cable you are wearing out the harness. I thought you would but I

:14:25.:14:28.

don't notice it at all. So what have you discovered about the kind of

:14:29.:14:32.

games that are best in this environment? Our rule of thumb is

:14:33.:14:35.

any more than one button is to constipated. Most of the people

:14:36.:14:39.

playing have never played VR before and it is enough of a surprise for

:14:40.:14:43.

them to find themselves in the game, you don't want them to have to

:14:44.:14:46.

remember six or seven button combinations as well. Double your

:14:47.:14:56.

gun, double your fine! So this is where nice simple games can be

:14:57.:15:01.

demonstrated. Wave shooter. Waves and waves of bad guys trying to

:15:02.:15:04.

attack me. The aim is simple. Fight them off. How do people fare when

:15:05.:15:14.

they have been in VR after a couple of drinks? It's a bit like playing

:15:15.:15:18.

pool. You get progressively better and then lots worse suddenly. It's

:15:19.:15:23.

really frantic. I don't think I could stand blogger than five

:15:24.:15:25.

minutes because I am getting really hot! And I'm dead. Well, it is

:15:26.:15:34.

turn to order at the bar. Now, does turn to order at the bar. Now, does

:15:35.:15:47.

this look like a racetrack to you? Does this look like a car? Last

:15:48.:15:53.

weekend six teams took to the track in Toulouse in France for the

:15:54.:16:01.

world's first Nano car race. The Nano cars are specially designed

:16:02.:16:07.

molecules which are invisible to the human eye. Nano things are very

:16:08.:16:12.

small. One nanometre is 30,000 times thinner than human hair.

:16:13.:16:37.

Six teams competed, representing France, Switzerland, Japan, Germany,

:16:38.:16:45.

the USA and there was a joint US and Austrian team. The tiny race track

:16:46.:16:49.

for most teams was maimed of gold. This is because it is so soft its

:16:50.:16:55.

service can be made extremely flat, as in not even an atom out of place.

:16:56.:16:57.

That takes some time to prepare. Once the Nano cars were in position

:16:58.:17:22.

on the track, the teams used the tip of a scanning, tunnelling microscope

:17:23.:17:26.

to propel the vehicles with tiny electric charges. They had 30 hours

:17:27.:17:34.

to raise 100 nanometres and back. Six teams started with no guarantee

:17:35.:17:37.

they would all finish. But there is historical precedent.

:17:38.:18:05.

In the end, it took one team only 90 minutes to finish the race. But they

:18:06.:18:15.

did use a different track. If we had used the gold it would have been

:18:16.:18:18.

silver service which is actually silver service which is actually

:18:19.:18:23.

slower, so we slowed it down, so we could control it better around the

:18:24.:18:26.

pylon. We never revealed the structure of our car until race day.

:18:27.:18:31.

There was no requirement to. We worked so hard to come up with these

:18:32.:18:35.

design features we did not feel we wanted to reveal that to the world

:18:36.:18:40.

until race day. Looking at their cars, we knew they were going to be

:18:41.:18:45.

a little bit slower because, number one, they were very big. The higher

:18:46.:18:49.

the molecular weights, the harder to move it. Number two, they had

:18:50.:18:53.

aromatic wheels, we knew that would slow them down. Even though it was

:18:54.:18:59.

then a 30 hour race, we knew we then a 30 hour race, we knew we

:19:00.:19:04.

would finish much faster than that. The second team to finish raced on

:19:05.:19:08.

the standard gold course and took over seven hours. The organisers

:19:09.:19:13.

decided to declare both the Swiss team and the US Austrian team joint

:19:14.:19:18.

winners as they raced in different circumstances. The tech used in the

:19:19.:19:21.

race will help improve the imaging capabilities of the world's most

:19:22.:19:26.

powerful microscopes and the car design process has pharmaceutical

:19:27.:19:28.

applications for making designer molecules. As it was, in the world's

:19:29.:19:35.

first banner race, every team will have plenty of thinking to take back

:19:36.:19:42.

to their tiny drawing boards. Now, you may remember last year we

:19:43.:19:47.

tickled your earbuds with something called binaural sound. This is a way

:19:48.:19:51.

of recording audio so you listen back through headphones and the

:19:52.:19:54.

sounds sound like they are coming from 3-D space. It turns out someone

:19:55.:20:01.

was listening. Not just someone, but the Doctor. He invited Kate Russell

:20:02.:20:11.

have a look. Why me? You're have a look. Why me?

:20:12.:20:15.

physically the biggest. Maybe as the physically the biggest. Maybe as the

:20:16.:20:28.

central heating. Oh, sorry. Did not mean to scare you. Unlike a new

:20:29.:20:36.

episode of Doctor Who that uses binaural sound to get inside your

:20:37.:20:41.

head. I have come to south Wales where the episode Not Knock was

:20:42.:20:48.

filmed. In this spooky looking house the Doctor investigates some strange

:20:49.:20:53.

noises. What is going on? Using binaural sound the show's produces

:20:54.:20:58.

can ramp up the fright factor by placing sound effects all around the

:20:59.:21:01.

listener so they feel like they are inside the room with the actors. If

:21:02.:21:07.

you see a normal digital audio work station everything is layering

:21:08.:21:11.

tracks. But we can see those tracks on the computer as objects, like you

:21:12.:21:16.

are looking down on a Rome, so you can see these dots with a cross

:21:17.:21:24.

showing where the axis is. When they are put through into the BBC

:21:25.:21:28.

renderer, then you can see where those sounds are hanging in 3-D

:21:29.:21:34.

space. To mix periods the binaural effect you must be using stereo

:21:35.:21:40.

headphones. Even a top of the range 5.1 surround sound system won't

:21:41.:21:47.

deliver the results because the microscopic time delays are vital to

:21:48.:21:53.

creating the 360 degrees immersive effect. That was super scary and

:21:54.:21:57.

spooky and atmospheric. Very subtle. You are expecting the kind of

:21:58.:22:02.

sideshow act of jumping around sound that wows you, that is not what this

:22:03.:22:08.

is about. This is a subtle experience of placing you in a

:22:09.:22:13.

three-dimensional soundscape. The reason why this episode lends itself

:22:14.:22:18.

so brilliantly to the binaural mix is because is it is playing with the

:22:19.:22:21.

horror genre and the tropes of that. A lot of what makes things scary is

:22:22.:22:27.

what you do not see. Building up the atmosphere to that moment of scare.

:22:28.:22:31.

That Israeli what the audience are looking for. We were told 3-D TV

:22:32.:22:37.

did not happen. So why should this did not happen. So why should this

:22:38.:22:42.

binaural is taking off now is binaural is taking off now is

:22:43.:22:46.

because we are in the age of the smartphone and tablets. People are

:22:47.:22:50.

consuming their media with headphones. The headphones are

:22:51.:22:51.

hugely popular. Even in my family, hugely popular. Even in my family,

:22:52.:22:57.

my kids will sit down watching their own content with a pair of

:22:58.:23:00.

headphones so as not to disturb each other. I think what will happen when

:23:01.:23:07.

people experience binaural audio with TV content, radio content, then

:23:08.:23:10.

they go back to stereo, they will feel a bit... It is quite

:23:11.:23:17.

claustrophobic and you think I want that others sound, that binaural,

:23:18.:23:21.

let me have more of that. I think that is where we will see it start

:23:22.:23:24.
