:00:09. > :00:16.This week, the coolest history lesson in history. The smallest car
:00:17. > :00:19.race in the world. And we are with the Doctor as something goes bump in
:00:20. > :00:50.the night. School, it has changed a lot since I
:00:51. > :01:00.went through the mangle all those years ago. Many. Years ago. School
:01:01. > :01:04.buildings may look the same but technology has been infusing
:01:05. > :01:09.education for some time. We have smart whiteboards, increasing use of
:01:10. > :01:13.instead of textbooks, but also there instead of textbooks, but also there
:01:14. > :01:19.are some systems which mean the way kids learn and are taught is
:01:20. > :01:23.changing completely. It seems many tech giants want to become part of
:01:24. > :01:26.education. After all, an early introduction to their brands may one
:01:27. > :01:32.day at up to a greater number of users. Microsoft this week launched
:01:33. > :01:36.its education offering which includes a new version of Windows
:01:37. > :01:42.called Windows S, a budget surplus pro in various colours and some
:01:43. > :01:46.treats to its office applications. Apple's teaching tool Classroom had
:01:47. > :01:50.a face-lift last month and now offers mortals the teachers, but
:01:51. > :01:56.before both of these came Google classroom. Today I am finding out
:01:57. > :01:59.more about it from the director of learning at training secondary
:02:00. > :02:02.online system the past 18 months to online system the past 18 months to
:02:03. > :02:09.teach and monitor the student' progress. Today I am learning about
:02:10. > :02:11.the Galapagos Islands and the lesson Chris has constructed
:02:12. > :02:15.looks more engaging than my old looks more engaging than my old
:02:16. > :02:19.textbooks. But tech can do a lot more than provide media rich lesson
:02:20. > :02:24.plans. We are able to personalise what we do more than before. We can
:02:25. > :02:29.take them to different resources available on the system. Every
:02:30. > :02:32.student's learning journey will be different. Taking teaching online
:02:33. > :02:38.means teachers have more access to children's individual learning data
:02:39. > :02:42.and even their thought processes. This browser extension lets the
:02:43. > :02:49.teacher watch how an essay was written and refined. If I have a
:02:50. > :02:52.student who in preparation for exams is not constructing paragraphs
:02:53. > :02:57.correctly I can say let's look at how you constructed your particular
:02:58. > :03:02.paragraph. What did you do? Where did you develop it? What can we do
:03:03. > :03:05.differently? If it is maybe two or three paragraphs and they spend so
:03:06. > :03:09.long on the first one, I can also say this is how long you spend on
:03:10. > :03:13.the first one, half an hour, Yuri spent part five minutes on the
:03:14. > :03:19.second and third. The kids also seem to like it. Lots of time we can
:03:20. > :03:22.still work at home and teachers can still be there on our thing and see
:03:23. > :03:27.how much we have done. If the teacher doesn't believe you have
:03:28. > :03:31.spent the required amount of time on the home work, you can say I did,
:03:32. > :03:39.look at the edit history. It is so much quicker, handing in work, you
:03:40. > :03:43.can hand it in and within 20 minutes have it back. Using online tools and
:03:44. > :03:49.data is one way to enhance learning in schools. But Lara Lewington has
:03:50. > :03:56.been looking at other tech which promises to change how children
:03:57. > :04:01.learn completely. VR, robots, holograms, it was not
:04:02. > :04:08.like this in my day! At the Best Can extrication show, we saw some of the
:04:09. > :04:12.most cutting edge ideas heading to the classroom soon. Over the last
:04:13. > :04:16.few months I have seen quite a few devices that bring together the idea
:04:17. > :04:21.of kids coding and toys, aiming to make it more fun, but good old Lego
:04:22. > :04:24.have gone a step further. They are trying to recreate real life
:04:25. > :04:28.situations where robots would be used so that children can find
:04:29. > :04:33.problems and then find a solution. The mission we have here is for a
:04:34. > :04:36.space robot which needs to move around the space base, collecting
:04:37. > :04:42.these pieces together and taking them back to one place. Obviously,
:04:43. > :04:49.the coding should do that bit. Using the Dragon drop box to create
:04:50. > :04:52.sequences that carry out actions as part of the learning process, as
:04:53. > :04:59.science is being taught at the same time. But brick so's vision of what
:05:00. > :05:04.can be learned is quite different. This is a way to bring your existing
:05:05. > :05:10.Lego set to life. It has some LED lights, a sense that, and these
:05:11. > :05:13.locks conduct electricity! From there you can create what ever
:05:14. > :05:17.spreading, moving, lighting functions create your fancy. But
:05:18. > :05:24.this use of technology is not just about teaching ICT, this adaptive
:05:25. > :05:27.learning is about employing new methods of teaching traditional
:05:28. > :05:34.classes. The teacher guides the experience but the student... This
:05:35. > :05:38.is Google Expedition. Jenny is going to play the part of a teacher, she
:05:39. > :05:43.will talk through what we are looking at in the goggles. It
:05:44. > :05:49.represents all of you... The pictures are amazing. Looking at the
:05:50. > :05:53.difference between the healthy and smoker's lungs I think we'll stick
:05:54. > :05:57.with them. The idea of an image in your mind is easier to maintain than
:05:58. > :06:00.someone talking. My issue is actually with the idea of the
:06:01. > :06:04.goggles. They are fine for a couple of minutes but then I feel the urge
:06:05. > :06:11.to take them off, I can't imagine wearing them for a full lesson. Many
:06:12. > :06:15.of these ideas will be picked up by individual schools, but although the
:06:16. > :06:20.ideas and devices are out there the challenge comes in making them
:06:21. > :06:23.available to the masses. That is something that one not-for-profit
:06:24. > :06:25.Finland, a country considered to Finland, a country considered to
:06:26. > :06:31.have one of the worlds best education systems, is to overcome. I
:06:32. > :06:36.would say education is when of the few big industries that is still
:06:37. > :06:39.waiting to be disrupted. One of the biggest challenges in the system is
:06:40. > :06:45.that it is based on the ideas of the industrial world. It is teaching
:06:46. > :06:50.everyone to be the same. In tomorrow's world it is crucial to be
:06:51. > :06:55.individual. One idea turns things on its head. Focusing not simply on new
:06:56. > :07:01.ways of teaching but firstly analysing how we learn. I am on my
:07:02. > :07:04.way to maths class which should cause me some concern because I'm
:07:05. > :07:08.not sure I remember that much from school. But with this class
:07:09. > :07:17.everybody is having their own private lesson. The teacher does not
:07:18. > :07:21.stand up and project their voice to start the session, the kids take
:07:22. > :07:25.their places at computers where AI will take them through the lesson.
:07:26. > :07:30.This artificial intelligence system aims to teach each pupil at their
:07:31. > :07:35.own pace and in the way that suits them best. Constantly gets to know
:07:36. > :07:39.them better and track in their process. The purpose of this machine
:07:40. > :07:44.is to learn how your brain learns and then utilise that data, is
:07:45. > :07:47.constantly adapts to provide them with a top tier education at every
:07:48. > :07:52.moment. And then take that data and offer it to the teacher in reason
:07:53. > :07:56.real-time. Here the student generates the data. It is provided
:07:57. > :08:00.in real-time to teachers, they can intervene when necessary and they
:08:01. > :08:06.can spend more time on human interaction with the student, the
:08:07. > :08:10.pastoral care they need to provide. Teachers can share their content
:08:11. > :08:15.around the world with other people using the system. Any given subject
:08:16. > :08:20.could have numerous options machine can select from based on the
:08:21. > :08:24.student's focus and learning levels. And if they choose to manually
:08:25. > :08:31.switch it tracks and considers their preferences to. What you feel are
:08:32. > :08:34.the chances? If you're not to share on question, it is easier to have a
:08:35. > :08:40.human explain it to you. But the commute pewter makes it as easy as
:08:41. > :08:41.possible. While I can see the benefits, there is one
:08:42. > :08:49.on my mind. That is the amount of on my mind. That is the amount of
:08:50. > :08:53.screen time. We have had plenty of teachers not just parents, saying do
:08:54. > :08:57.we want them staring at the screen? The answer is not binary. That is
:08:58. > :09:01.important. We don't think teachers should be replaced, we need more
:09:02. > :09:06.teachers, but we think they should spend their time teaching inspiring,
:09:07. > :09:09.imparting knowledge of a stubbed it they really understand. There is no
:09:10. > :09:12.shortage of ideas yet naturally putting them to the test requires
:09:13. > :09:18.people willing to take the chance on them. Clearly the idea of technology
:09:19. > :09:28.giving an overhaul to how we educate our kids does not seem far away.
:09:29. > :09:36.Welcome to the week in Tech. It was the week that Elon musk talked about
:09:37. > :09:40.tunnels again. He has proposed underground network where your car
:09:41. > :09:45.is shuttled from A to B on an electric skate that could go up to
:09:46. > :09:52.130 mph. The name of it, the boring company. It was also the users of
:09:53. > :09:54.what set were asked what is happening after the service went
:09:55. > :09:59.down for several hours around the world. The bank accounts of O2
:10:00. > :10:06.customers in Germany were drained after the S S seven mobile telecoms
:10:07. > :10:10.system was hacked. We covered their vulnerability last year. In Sweden
:10:11. > :10:17.and the world's fastest camera has been developed. It can capture 5
:10:18. > :10:25.trillion images per second. Others, typically get 100,000. Instead of
:10:26. > :10:29.captured an image is one it captures several at once and pieces them
:10:30. > :10:35.together into video. It can be used to video things like brain activity
:10:36. > :10:40.and chemical reactions. Finally, innovative help robots run better,
:10:41. > :10:46.this ostrich like bot can sprint up to ten mph and can self balance
:10:47. > :10:51.without the need for sensors or computer processing. A single motor
:10:52. > :10:54.drives its legs forwards in an elliptical motion in jet and more
:10:55. > :11:05.power when it feels resistance. It has a mind of its own! Everyone down
:11:06. > :11:13.to the pub for a swift half, a game of bar billiards and a battle with
:11:14. > :11:17.giant bugs. The perfect evening. There are a couple of things you
:11:18. > :11:23.always find in a British pub. Number one, pints of beer. In some drinking
:11:24. > :11:31.shops there are distractions like darts. And of course virtual reality
:11:32. > :11:38.find your pint? The big problem for find your pint? The big problem for
:11:39. > :11:42.most people with virtual reality is space. You don't have the space in a
:11:43. > :11:48.normal sized living room to play the ER games properly. The headsets have
:11:49. > :11:53.cables attached which you can trip over and then you have furniture and
:11:54. > :11:57.walls to bang into. That is where pubs come in. Pubs are generally
:11:58. > :12:04.bigger than the house you live in so there is no problem with space. And
:12:05. > :12:06.they afford you the opportunity for truly social virtual reality
:12:07. > :12:14.experience is because people can see what you are doing. So the wars in
:12:15. > :12:18.here are green. That means the spectators watching me play can see
:12:19. > :12:24.the environment I am in and if I back myself up to them I feel they
:12:25. > :12:30.are soft. They are padded, so payers cannot injure themselves if they get
:12:31. > :12:36.too energetic and throw themselves around. It is like a soft play area
:12:37. > :12:40.for adults. The combination of public house and virtual reality is
:12:41. > :12:43.the brainchild of these guys, they have used their backgrounds in
:12:44. > :12:48.satellite technology, IT and engineering to create this setup.
:12:49. > :12:57.What made you think that VR and pubs when together? We wanted to do a VR
:12:58. > :12:59.arcade, but finding arcades have a stale and outdated image. So we were
:13:00. > :13:03.looking for a good venue to do looking for a good venue to do
:13:04. > :13:07.virtual reality in public. When you are involved with alcohol there is
:13:08. > :13:13.always a degree of risk to the gear and the equipment. So we have had to
:13:14. > :13:18.rig up our nurses so that if people fall over they do not damage
:13:19. > :13:24.themselves, the harness also protect the headsets so they don't fall on
:13:25. > :13:31.the ground. Enough talk. Time to try out the specially designed VR rake.
:13:32. > :13:35.We have it plugged into this seat belt arrester system. It will catch
:13:36. > :13:39.you if you fall. In order to make it safe, it is crucial that cables are
:13:40. > :13:45.kept out of the way. I have a harness I have to put on. It goes on
:13:46. > :13:49.there. And then we put this in at the back. And now, no matter how
:13:50. > :14:00.much you turn around, the cable will not get caught. An ingenious
:14:01. > :14:05.solution to the cable problem. Now I've played tonnes of games in VR
:14:06. > :14:10.before, and as always I am immediately transported from the
:14:11. > :14:14.space I was in into this sewer. Zombies coming from pretty much
:14:15. > :14:24.every direction. Gunn shot reload, reload! You don't really notice the
:14:25. > :14:28.cable you are wearing out the harness. I thought you would but I
:14:29. > :14:32.don't notice it at all. So what have you discovered about the kind of
:14:33. > :14:35.games that are best in this environment? Our rule of thumb is
:14:36. > :14:39.any more than one button is to constipated. Most of the people
:14:40. > :14:43.playing have never played VR before and it is enough of a surprise for
:14:44. > :14:46.them to find themselves in the game, you don't want them to have to
:14:47. > :14:56.remember six or seven button combinations as well. Double your
:14:57. > :15:01.gun, double your fine! So this is where nice simple games can be
:15:02. > :15:04.demonstrated. Wave shooter. Waves and waves of bad guys trying to
:15:05. > :15:14.attack me. The aim is simple. Fight them off. How do people fare when
:15:15. > :15:18.they have been in VR after a couple of drinks? It's a bit like playing
:15:19. > :15:23.pool. You get progressively better and then lots worse suddenly. It's
:15:24. > :15:25.really frantic. I don't think I could stand blogger than five
:15:26. > :15:34.minutes because I am getting really hot! And I'm dead. Well, it is
:15:35. > :15:47.turn to order at the bar. Now, does turn to order at the bar. Now, does
:15:48. > :15:53.this look like a racetrack to you? Does this look like a car? Last
:15:54. > :16:01.weekend six teams took to the track in Toulouse in France for the
:16:02. > :16:07.world's first Nano car race. The Nano cars are specially designed
:16:08. > :16:12.molecules which are invisible to the human eye. Nano things are very
:16:13. > :16:37.small. One nanometre is 30,000 times thinner than human hair.
:16:38. > :16:45.Six teams competed, representing France, Switzerland, Japan, Germany,
:16:46. > :16:49.the USA and there was a joint US and Austrian team. The tiny race track
:16:50. > :16:55.for most teams was maimed of gold. This is because it is so soft its
:16:56. > :16:57.service can be made extremely flat, as in not even an atom out of place.
:16:58. > :17:22.That takes some time to prepare. Once the Nano cars were in position
:17:23. > :17:26.on the track, the teams used the tip of a scanning, tunnelling microscope
:17:27. > :17:34.to propel the vehicles with tiny electric charges. They had 30 hours
:17:35. > :17:37.to raise 100 nanometres and back. Six teams started with no guarantee
:17:38. > :18:05.they would all finish. But there is historical precedent.
:18:06. > :18:15.In the end, it took one team only 90 minutes to finish the race. But they
:18:16. > :18:18.did use a different track. If we had used the gold it would have been
:18:19. > :18:23.silver service which is actually silver service which is actually
:18:24. > :18:26.slower, so we slowed it down, so we could control it better around the
:18:27. > :18:31.pylon. We never revealed the structure of our car until race day.
:18:32. > :18:35.There was no requirement to. We worked so hard to come up with these
:18:36. > :18:40.design features we did not feel we wanted to reveal that to the world
:18:41. > :18:45.until race day. Looking at their cars, we knew they were going to be
:18:46. > :18:49.a little bit slower because, number one, they were very big. The higher
:18:50. > :18:53.the molecular weights, the harder to move it. Number two, they had
:18:54. > :18:59.aromatic wheels, we knew that would slow them down. Even though it was
:19:00. > :19:04.then a 30 hour race, we knew we then a 30 hour race, we knew we
:19:05. > :19:08.would finish much faster than that. The second team to finish raced on
:19:09. > :19:13.the standard gold course and took over seven hours. The organisers
:19:14. > :19:18.decided to declare both the Swiss team and the US Austrian team joint
:19:19. > :19:21.winners as they raced in different circumstances. The tech used in the
:19:22. > :19:26.race will help improve the imaging capabilities of the world's most
:19:27. > :19:28.powerful microscopes and the car design process has pharmaceutical
:19:29. > :19:35.applications for making designer molecules. As it was, in the world's
:19:36. > :19:42.first banner race, every team will have plenty of thinking to take back
:19:43. > :19:47.to their tiny drawing boards. Now, you may remember last year we
:19:48. > :19:51.tickled your earbuds with something called binaural sound. This is a way
:19:52. > :19:54.of recording audio so you listen back through headphones and the
:19:55. > :20:01.sounds sound like they are coming from 3-D space. It turns out someone
:20:02. > :20:11.was listening. Not just someone, but the Doctor. He invited Kate Russell
:20:12. > :20:15.have a look. Why me? You're have a look. Why me?
:20:16. > :20:28.physically the biggest. Maybe as the physically the biggest. Maybe as the
:20:29. > :20:36.central heating. Oh, sorry. Did not mean to scare you. Unlike a new
:20:37. > :20:41.episode of Doctor Who that uses binaural sound to get inside your
:20:42. > :20:48.head. I have come to south Wales where the episode Not Knock was
:20:49. > :20:53.filmed. In this spooky looking house the Doctor investigates some strange
:20:54. > :20:58.noises. What is going on? Using binaural sound the show's produces
:20:59. > :21:01.can ramp up the fright factor by placing sound effects all around the
:21:02. > :21:07.listener so they feel like they are inside the room with the actors. If
:21:08. > :21:11.you see a normal digital audio work station everything is layering
:21:12. > :21:16.tracks. But we can see those tracks on the computer as objects, like you
:21:17. > :21:24.are looking down on a Rome, so you can see these dots with a cross
:21:25. > :21:28.showing where the axis is. When they are put through into the BBC
:21:29. > :21:34.renderer, then you can see where those sounds are hanging in 3-D
:21:35. > :21:40.space. To mix periods the binaural effect you must be using stereo
:21:41. > :21:47.headphones. Even a top of the range 5.1 surround sound system won't
:21:48. > :21:53.deliver the results because the microscopic time delays are vital to
:21:54. > :21:57.creating the 360 degrees immersive effect. That was super scary and
:21:58. > :22:02.spooky and atmospheric. Very subtle. You are expecting the kind of
:22:03. > :22:08.sideshow act of jumping around sound that wows you, that is not what this
:22:09. > :22:13.is about. This is a subtle experience of placing you in a
:22:14. > :22:18.three-dimensional soundscape. The reason why this episode lends itself
:22:19. > :22:21.so brilliantly to the binaural mix is because is it is playing with the
:22:22. > :22:27.horror genre and the tropes of that. A lot of what makes things scary is
:22:28. > :22:31.what you do not see. Building up the atmosphere to that moment of scare.
:22:32. > :22:37.That Israeli what the audience are looking for. We were told 3-D TV
:22:38. > :22:42.did not happen. So why should this did not happen. So why should this
:22:43. > :22:46.binaural is taking off now is binaural is taking off now is
:22:47. > :22:50.because we are in the age of the smartphone and tablets. People are
:22:51. > :22:51.consuming their media with headphones. The headphones are
:22:52. > :22:57.hugely popular. Even in my family, hugely popular. Even in my family,
:22:58. > :23:00.my kids will sit down watching their own content with a pair of
:23:01. > :23:07.headphones so as not to disturb each other. I think what will happen when
:23:08. > :23:10.people experience binaural audio with TV content, radio content, then
:23:11. > :23:17.they go back to stereo, they will feel a bit... It is quite
:23:18. > :23:21.claustrophobic and you think I want that others sound, that binaural,
:23:22. > :23:24.let me have more of that. I think that is where we will see it start
:23:25. > :23:31.to take off. This spooky episode will be broadcast with regular sound
