the info is and all the input u. v. w story. now on to the, to choose and send and emoji to someone you only need thumbs. but writing with a pen or pencil involves the entire hand. it's a veritable anatomical wonder made up of 27 different bones, a perfect multi functional tool with close ties to the brain. writing things out by hand, improve recall, how come that topic and much more this week on dw science program tomorrow today. welcome to the show, the newborns will grab woods in their immediate environment. they have an innate grasp reflex. it probably

originally rose from the need to reflectively latch on to a mother, animals for the pin. so go ahead, which involves coordinating with the sun, only starts to develop around 6 months. the grasp reflex is subsequently lost and training improves dexterity, and daily life. most children can tie their own shoelaces by the age of 4 and learned to right in the 2nd grade class and the small but very good town of old. today's lesson plan includes handwriting. see if i can, i can see that so many of you, the training is really paying off of the writing by hand is a complex process. during this activity, 12 areas of your brain are active and more than 30 muscles and 17 joints in the hand have to work together. malia, near the d, as my eye is

a researcher at an institute dedicated to the topic. she's here today to observe how individual children use their hands when writing how do they hold the pin? do they write fluently, or do they tense up? it should ivan down and it's really learning to rise to is learning to move comes for the for when we talk about him by saying we're not just talking about finished classes, but the movement that leads to hand writing i'm sitting here writing by hand creates a memory trace in the brain, different letters lead to corresponding movements. so this makes learning easier. and mrs. highlight, rising cost is and i find it pretty easy, but it also helps my owns a bit. so for those 2 types of some people, surveys have shown that children are losing interest in writing. now again, new ideas maya has observed that as well along with something else. just behind

city comes, warranty is deteriorating, driving the children, don't write. they write faulty slowly and they tend saw and they write diarrhea let you play 5 months, at least at least half of all boys in elementary school. and $1.00 and $3.00 girls have problems with writing according to germany's national teachers association. weaknesses can be detected with the help of a special digital pin, a touch sensitive screen under the paper measures pressure movements and speed of writing to send evaluate the data directly along the one in dolton l l l 3 times. then one more time. 3 times stop, stop. the test also allows melody and the ideas mile to clearly explain to the children what they're doing wrong, should i know you're right fox,

you can do it very well, then it gives you a speed is very good for your age and i yeah, this looks on this but you pressed a little too hard and we're going to do an exercise for that. now on this, i know the results help myers institute develop freely accessible methods that can be easily implemented by teachers. they also help train kids fingers in a plateful way. and then we do this so that we don't always press so hard on the pen. that's money to pick them up to you as soon as you like. sedation increases, they write foster when they copy from the blackboard. for example, when teachers come encouraged us even more in charge for this, i have done enough that the, despite the for the father, the writing down stories dictated by the teacher is also a good way to practice. even a single hour of hand training every week brings measurable progress because it

helps many children enjoy writing more. but enjoyment as far from the only factor playing a role. when we would like the children to spend less time in front of screens huffman, our less with technical media, and instead do stuff kids like to do experience nature, bait cookies at home, need to play with water. in other words, every thing that's experienced have typically with the hands, talk to somebody and him some alfonze at the time. so i haven't heard of writing must not be replaced. it's very valuable for our brains. digitalization isn't the on to success, but we should be using it where it's appropriate to moment, then not the the digital age has given rise to many programs aimed at making writing easier.

practically every cell phone now has a voice to text puncture, and that's all that. but artificial intelligence has taken things to the next level with tools like chat, g, p, t, tell it to write an essay on a particular topic. and it'll turn one out and seconds off and not 100 percent correct, or stylistically perfect. even. so a, i, it's posing a tricky di, lemme for schools at this elementary school in switzerland, kids are getting involved with a i, as an early age then the old amount is one of the 1st primary school teachers in the country to teach 10 and 11 year olds, healthy use a i the concert if you can always ask for help, but you also always have to be critical and ask yourself whether it's the right thing to do. if you need to do something with the chat, abt, there's one computer here in the front. and another in the back is

the kids can only access top g p t on to school computers. and the accounts belong to the school. the class walks on different tasks. one is to us, we talked to d today. who am i? make a riddle about the level. i don't think i could have made such a good riddle about myself. it doesn't so well from so little information much sooner be so good. this is just kind of exciting because it's like an artificial intelligence and can do stuff . you tell it to do, which is pretty cool. but when you ask, have certain questions, it doesn't really work properly get this stuff up useful, finished on the, on the city. since it's exciting to see how fast it collects information from the

internet and how well it can write text as it should be on the web hosting. do you have just one version or did you ask several times? i asked twice. the 1st time i rose to make a riddle about me, i'm 10 and i love dogs. and then it said i was adult too much. it's good for you to realize that you can make a new version and always improve and change this. and i'm thinking and then the old amount things chunk g p t problems like those being discussed in other schools or in the state police. it's important to provide kids with the right tools for the future, especially when it comes to important technological development. between from while we teach computer science and you might think that means we teach kids how to use a computer or how one works. but at its core, it's about media education in media. the student should learn how to use such media

and chat, g p t for because an essential part of that. it's also a facet of dealing with new developments and the artificial intelligence behind testing, which takes things one step further to gold. what the youngest school kids are still playing around with this already grade more concrete for all the ones that every day school life as all visit to the school in menacing and shows. the goal here is to lead the pack in terms of digitalization and in the classroom chemistry languages, algebra. teach us here right now. incorporating chat g p t into lessons, and practically every subject. in miss smith's class middle school students of finding out how well chunk g p t can handle complicated arithmetic issues. you think the question is whether the solutions are correct?

get all this, do i go to different results? when else the right questions? test g, p t come spits out solutions that help the students solve math problems on that right. past the system that responds to individual needs, the position comes close to the airport. so it's very good at analyzing tasks, you know, and it's very good at explaining how to solve them and it was almost, but it can't actually solve the problems for you often lose the house. i listened these fellows to that's not fit to be, especially when it comes to math. it's often wrong that's a foolish, but it's good. it's suggesting what you have to do and explaining what it's actually about breaking down to us and explaining them in simpler terms, is clear that i have to admit that with was the 2nd groups. and especially for someone like me who has a hard time with math, it's definitely a help to remove the streets for the math teacher, you're not supposed to go sees great potential. and i, even if it comp the math very well piece especially happy to have some multiples in

the run up to final exams. you'll need to. so i don't have time to go over every question individually with each student. it's just not possible. and the time we have available these days, ones for thought. so in that way it's sensational. there might be some default, but it's like you have a partner who can answer certain questions for you guys. and as a teacher, you know which questions the partner can answer well and which ones you have to take over yourself as an insoluble amount. and if you understand that, then you can use it efficiently. but suffice nicole to say, so say i can see on things that fellow teacher might know supply as a german teacher at the same school deal. so regularly uses chuck g p t. and his less of you, in the, i mean we're in the middle of preparing an essay. and today the aim is for you all to get feedback on a draft that you've already written. it should even hoffen on. and for that,

we need to talk about what prompt we need to enter, and whether it's good to him by popular e style or tech structure. students had learned how to write good prompts, the entries in chat g p t. this time the, i a suppose to get some specific tips on wherever and how to improve their essays as it tends to be taking its activity 1st, told me that the pros and cons i entered here could be structured more clearly i should feed things. so i did that and then re entered it, and then it said, well done. well, it works now. i also think the text is better now, do the structure is generally better if any specific it reads better and more clearly spin sad it improve the flow and made my argument smoke here, and it's amazingly specific. it took bits out and rewarded them. it was much better than the original. the original 6, the german teacher isn't worried about his people's getting lazy or trying to cheat on the comments, right? lucky alternative for additional causes, it ends in plagiarism existed before now it's nothing new. and of course,

if the text is too perfect, if and you know the student comes and how their writing has developed it, if something doesn't fit, you can just ask nichol. i also think the students know that they'll ultimately have to manage without catching meetings with them. with the rise of a i tools like chunk g p t. it's important that young people learn how to navigate them and use them to their advantage. but there's one aspect of learning where a i can't help you studying for and taking tests for most school kids and students of very stressful process. many feel overwhelmed before hand. let's take a look at what's going on and how to overcome the fear of exams. oh no, i'm not going to make it. i need some sleep. but what if i fail the exam?

doesn't use this sounds familiar with college. life is no joke. you want to perform your best, but often it's hard to stay focused and disciplined all the time. but it is possible to beat the college stress and face your exams. let's explode the science behind that. the, the stress head students all over that was a number of seem to have increased. for example, do out of 5 college students suffer from anxiety, $1.00 and $3.00 even from depressive. symptoms covered has had its own part to play him. but stress for say, is not bad. it can make us do well in exams. stress straps up our body and mind and import into dangerous situations. it increases hormones like drilling, denellin,

and cortisol, which speed of a hard to improve of concentration. a body has been doing this for centuries to coal, puts dangerous and important situations. it's called the fight or flight response. but when stress tomlins reach very high levels, the system and then performance and concentration decrease. typical signs and symptoms of high stress levels can be a founding hard headaches, nausea and for sleep and problems. concentrating in extreme cases, stressed into the anxiety that can make you go completely blank in tests. so why does it feel like anxiety swallow is your knowledge been feel dominates box . so if i'm drains communication factories can get low regard to because anything we've learned, even though the information is stored in operating. because when stress hormones

are high, brains control center right behind the forehead. the prefrontal cortex stops regulating our thinking and emotions as it usually does. instead pulled about like b, i make the last the center for emotions and compulsive behavior decal and what we feel is feel oh, that's a split to now this before that that's, that's not me. but besides from being ready for bed, another important and such the as how and what you think in a stressful situation. thoughts like i'm a bit nervous but that's okay. can actually come you down but thoughts like i never make it. i fail, set off of this just cycle of feel and driving stress. com on the the good thing is you can do something about it. the bad thing. you might have to change some general habits in your life. one important aspect is taking breaks. even if

you are under time pressure engenders everything that relax as the body in mind hits with stress and anxiety that are some scientifically proven methods that really work. studies have shown the benefits of practicing mindfulness relaxation, breathing exercises and meditation. there are lots of apps on the market that offer these methods, but be a little careful which one you choose as only a few apps have been scientifically evaluated. see if you can find some information on it before using it. another important factor in feeling been balanced is a good night's sleep. yet to out of 3 students don't sleep enough. particularly during exam periods, they cut down on their sleep. it's really impacts it up to that make performance.

one of the primary functions of sleep is learning and memory. if you don't sleep, memory simply doesn't happen. how much sleep younger dose need is not clearly known, but it is thought to be around 8 hours. finally, let's talk about giving your day a bit more structure, set up a good plan defined times for rent and what you learn. and when you exercise, meet defense, listen to good music or use social media, especially in the 2 weeks before an exam. a good study plan has suddenly not tried to avoid last minute cramming and all nighters. and if you feel like you can't manage your stress, so things id, talk to people usually only trust like friends, family, or university counselors. don't hesitate to seek professional head. try to find out which of these fits has to you and there's

a good chance you'll say that most mostly to college life. even if you fail to test every now and again, it doesn't mean the end of the world. on the contrary, in the long run, it can actually help strengthen your ability to bounce back your resilience. no one succeeds at everything all the time, but some people deal with failure better than others can be trained. decent that him eyes as a psychologist to studies what helps people cope in moments of crisis. resilience plays a key role in the research. she and her colleagues even look into test subjects, brains, that term. resilience refers to the ability to cope with challenges. scientists recognize 3 basic types of cute and so i'm fine with us against both of us who resilience bonzai with me. because i think it nicely demonstrates the different ways that people react to adversity to pop things until they again come to have

been much in the when does life stefan latrice ways. but if you look at the trunk, it remains every time and stuff and stuff because i worked with some people, the stress bounces all my guesses pin that schooled resistance from that gave escapes me. other people felt less well and may develop symptoms of strengths of incentives. the, when the wind dies down a little which is corporate generation, they manage to regenerate and stop growing normally. again, i can just look up on this. i did the cool the windsor fly, started blowing when done, and then as a said type known as reconfiguration, perhaps what, i'm sorry, this is where the trunk changes that on that bonzai op on. so i didn't do so well for a while. it didn't get to the microsoft, but then it managed to grow in a new direction and i'm on by an example with the people who had come. so they also managed to develop new skills abilities and i did in order to be even better equipped in a matter of speaking. hey, mike, for instance, realize what's really important to them in their lives,

in stride housing completely new direction and all you these like they might quit the job, i hope to see very specific activities and hoping staff resilience used to be viewed as a kind of inborn characteristic one person might be more resilient to another less so. so research has shown that how resilience you are can change over the course of your life. how do i enter team want to understand exactly how it works. that in this case here we look into the brain because we found that to mozilla and people some struck to the fact that developed in the brain to put them into connected enough. and that's sodium looks like the mikaela, the son to for processing emotion bye to but also another important structure of the prefrontal cool toxic in the full brain. it's, it's responsible for thinking and planning this. and of course, these are also structures that can be trained on and because the ability can be trained isabella homepage and her team have founded the resilience, outpatient clinic. here of people can learn and develop specific resilience factors

and courses or an individual coaching sessions. for example, they learn to confront and take on situations that they find challenging and that even failure at times can have its positive sides. a little shy if i'm hunter, say here is of course no fill up the phone but the test positive line. no one gets 3 life without some crisis, right? so you have to practice failure and we should teach people. it's good to fail because you can learn from itself now and let us read. why do you have a science question? send it to us in a video text or voice message. if we answer it on the show, we'll send you a little surprises the thank you. so come on just that this week or a question comes from jorge enrique from el salvador the

. what can we learn from spiders? the spiders are most of builders that help a lot to teach us the they can produce so many times, find the human uh, the thread low enough to inside cool the clothes. which weigh less than a bar of sorry, the, the european gotten spider. we've subscribe from several different types of threats . a, spider silk is free of bacteria and also my crates more elastic, some night long and ground for ground, much stronger than steel. prey tangled up in spite of soak doesn't stand. the chumps a single thread can contain up to 1500 strums. the material force is produced in

the animals optimum and with the cold spin around, the spider slowly shapes its tread down to these clones. reset shows have been working for decades to replicate the price i saw sufficiently. ready ready ready ready to do so, they fast copied the dna segment from the slightest d 9 that provides the genetic recipe for soak. then they transplanted it into bacteria. the bacteria modified in this way start turning out the protein acts as a building block for spider silk. this rule material is then used to produce also special threads, even more or less to come, staples and then not tro counterparts. manufacturer's warranty makes me cuss from spider cell and coating. so medical implants, some cosmetic products also contain spine to salt proteins. the elastic material

is even use an ad across the twins and reset to see many more potential future applications for spite of silk, the we imagined about science and technology. that's like d. w signs is now on say what to do for fun. why do gravitational ways when did people begin getting high and laughing gas drums boogie to the beads and what's the perfect king footboard find? find the on says gets most dw science own new tick tock channel. and that wraps things up this week on dw science show. thanks for watching and see you again next time on tomorrow. today
