you will have to say that's why we listen to every weekend on d. w. 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, 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 what's 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 circle at 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 and this 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 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. molly, a new ideas. my uh, is

a researcher in an institute dedicated to the topic. she's here today to observe how individual children use their hands when. right. how do they hold the pin? do they write fluently or do they tense up? it should ivan, man, i mean, really learning to write his learning to me. i'm sort of 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 the learning easier and mrs. highlight rising cost saved 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 and writing. now the new ideas

maya has observed that as well, along with something else that's behind city comes, warranty is deteriorating, driving the children, don't write, they write faulty slowly, and they tend saw and they write very allegedly 5. and so, unless somebody needs to finish the half of all, boy you said elementary school and one and 3 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 and evaluating 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 low d as my o to clearly explain to the children what they're doing wrong. should i say now

you're right, fox, you can do it very well, then it gets your speed is very good for your age. awesome. yeah, this looks good, but you press a little too hard and we're going to do an exercise for that. now on this i know the results, health myers institute develop freely accessible methods that can be easily implemented by teachers. they also help train kids fingers in a playful 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 a teacher's comment encouraged us even more in size, but i saw him dining on the slide. the for the 4 of them, 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. i need to play with role. so in other words, every thing that's experienced have typically with the hands up to somebody, i'm having some fun. but the concert 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 for sticking moment on. most of the, the digital age has given rise to many programs and making writing easier.

practically every cell phone now has a voice to text function that's all had. 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 will turn one out in seconds off and not 100 percent correct or stylistically perfect. even. so a, i is posing a tricky di lemme for schools this elementary school in switzerland, chips with getting involved with a i at 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 cost 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 works on different tasks. one is to us contract t t t 2, i might make a riddle about the class. i don't think i could have made such a good riddle about myself. it doesn't so well from so little information what's thrown up. so what this is, i just find it 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 yet. if the stuff up is felt 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 a dish phone 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. and it's good for you to realize that you can make a new version and always improve and change for this. and i'm thinking thanks dana, 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 all 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 medium,

the student should learn how to use such media and the chat g p t for because an essential part of that fits. 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 until 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, chuck g p t come spits out solutions that help the students solve math problems on that right in the past. and the system that responds to individual needs, the position comes cost input. so it's very good at analyzing tasks, you know, and it's very good at explaining how to solve them and it almost, but it can actually solve the problems for you often lose the cost i less need us to. that's not to be, especially when it comes to math, it's often wrong that's a foolish, but it's good at suggesting what you have to do and explaining what it's actually about breaking down to us and explaining them in simpler terms of the candidates. i have to admit that it was the 2nd group and especially for someone like me who has a hard time with math, it's definitely a help during the streets for the math teacher, you're not supposed to go sees great potential. and i, even if it caught the master very well, he's especially happy to have some,

most of holes 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. maybe it's an a fault. 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 insoluble minds. and if you understand that, then you can use it efficiently. if it's vice and come at a safe to say, i could see on things that fellow teacher might know supply as a german teacher at the same school feel so regularly use this chunk, g p, t. and his lessons, you can see, 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. because should even hoffen on. and for that,

we need to talk about what prompt we need to enter. whether it's good to him by popular e style or text structure. students had learned how to write good prompts, the entries and chunk 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. the chief 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 cuz i also think the text is better now do the structure is generally better if at least expect it reads better and more clearly. spinach salad 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 common trait. lucky alternative, official 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 charging meetings with them. with the rise of 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, a 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 stress hid 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 ad, gentleman,

dominion, and cortisol, which speed of a hot and 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 hormones 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 swallows you knowledge feel dominates spots? so if i'm drains communication factories can get low regardless 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 her thinking and emotions as it usually does. instead pulled about like b like 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 the test that's nominated. but besides from being ready for bed, another important sash, the is 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 time 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 does 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 trust like friends, family, or university counselors. don't hesitate to seek professional head. try to find out which of the students help you and there's

a good chance you'll say that most mostly to college life. even if you fail a 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. he said that him, i is a psychologist who 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 humans. i'm fine with us. and again, i brought to this whole 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 to develop the vitreous ways. but if you look at the trunk, it remains every time and stuff and stuff because i love with some people, the stress bounces all one go. 10 thought schooled resistance from that games keeps other people felt less well and may develop symptoms of strengths of incentives. the when the wind dies down a little, which is corporate generations, they manage to regenerate and stop growing normally again, just look up on this i did before the wins of life started blowing. when done tony to put them as a sub type known as reconfiguration. cool. that's what i thought, this is why the trunk changes that one of the bonzai items 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 they've gotten familiar, these like they might quit the job well to see very specific activities and hoping to 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 send her team one to understand exactly how it works? that in this case, we look into the brain because we found it to missouri and people, some struck to the fact that developed in the brain to put them into connected enough. and that's very, i'm like the mikaela, the son to for processing emotional side. 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 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 don't have to say here is of course no fill up the phone but to dispose of like, 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 surprised since the thank you. so come on, just ask this week or a question comes from jorge enrique from el salvador

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

produced in the animal's optimum and was the cold spindle wrecked. the spider slowly shapes its tread out of these glands. researches have been working for decades to replicate the price i saw sufficiently. ready ready to do so, they fast copied the dna segment from the slightest d 9 that provides the genetic recipe for so then they transplanted it into a box area. the bacteria modified in this way. start turning out the protein, the opposite, the building blocks, the spider silk. ready this rule material is then used to produce also special threats, even more or less to can staples and then not tro counterpart manufacturers warranty makes me cuss from spite of self and coating. so medical implants, some cosmetic products also contain spite of salt proteins. the elastic material

is even used in 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 take time. what's funny, why do gravitational ways? when did people begin getting high and laughing gas out the drums boogie to the beads and what's the perfect kid football 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 the the,

we love your dress, the t n a no mountain is too high. the road is too long. in such a faith, ordinary we have a specialist of lifestyle, 009. coming up on d, w of the best suddenly a team interest in there, which is great for us. sasha,

with one daring goals to help smart nature. the more like watching on youtube dw documentary. so you don't feel the same way you expect and want different things from life than your parents. i just want to pursue was that's my thought was fired or you think you kid is 2 different risk, irresponsible, unreasonable, all stuff. porters those nonsense. i wonder what the doctor is there an alternative plan? everything to prevent a divorce, but nothing worth looking the time you were asleep and we're paying for now and then when generations last

this week on the discount in front of feels like the this is dw news and these are the top stories the u. s. s. 3 of its troops have killed and have killed a have been killed and dozens more wounded and drones drank on a base and ne jordan near the syria border. present job. i didn't blame. dive on back to militants for the attack. it's the 1st time american ministry personnel have been killed by a hostile fire in the region since the stock of the hum us israel will you and chief and 20 a good terrorist has a bonus days to guarantee.
