story behind the news, we read about unbiased information for free by 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 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. 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 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 a 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 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 rice has learning to move on. when we talk about him by saying we're not just talking about finished classes, but the movement that leads to handwriting and i'm sitting here. writing by hand creates a memory trace in the brain. different letters lead to corresponding movements to this makes 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 in writing math again, new ideas maya has observed that as well along with something else. the fiance

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 stipends, at least at least 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 evaluate the data directly. along the one in o 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 say now 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, health 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. there's money to pick them up as soon as like sedation increases, they write foster when they copy from the blackboard. for example, when teachers come encouraged us even more in size, but they still have done enough that is not the despite the for the, for the the reason that i'm 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. we would like the children to spend less time in front of screens huffman, our less with technical media, and instead of 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 hand in hand, some alfonze about 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 on, on the the digital age has given rise to many programs and 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 will turn one out in seconds off and not 100 percent correct or stylistically perfect. even. so a, i, it's posing a tricky dilemma for schools at this elementary school in switzerland, kids the getting involved with a i, as an early age then ultimately is one of the 1st primary school teachers in the country to teach 10 and 11 year olds. healthy use a i the constant 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 t t t who am i 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 is i 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 yet to discuss a peaceful, finished on the, on the cdc. since it's exciting to see how fast it collects information from the

internet and how well it can write text edition 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 left the 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 this. and i'm thinking sites 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 go. 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, touch g p t come spits out solutions that help the student solve math problems on that right? in the past, in 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 in almost what 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 essence and explaining them in simpler terms is clear that i have to admit that it 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. maybe it's in default and 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. it's a bicycle to say, so say i can see on things that fellow teacher mac notify is a german teacher at the same school deal. so regularly uses chuck g p t. and his lessons. you can tell me we're in the middle of preparing an essay and today the amos for you all to get feedback on a draft that you've already written to 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 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 judgments at t. v t 1st told me that the pros and cons i entered here could be structured more clearly i should be think 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, 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 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 nipple. i also think the students know that they'll ultimately have to manage without charging 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 is 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?

does any of this sound familiar with college? life is no joke. you want to perform your best, but often it's hot to stay focused and disciplined all the time. but it is possible to beat the college stress and a so your exams, let's explode the science behind that. the stress hid students all over. there 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 throughout

dominion and cortisol, which speed up our hearts 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, heart, 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. when field dominates spots, so if i drains communication factories can get low regardless because anything we've learned, even though the information is stored in operating. because when stress hormones

a high, a 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, date global. and what we feel is feel all as a split novice before the test that's nominated. but besides from being ready for bed, another important and faster is how and what you think in a stressful situation. thoughts like i'm a bit nervous but that's okay. i can actually calm you down. but thoughts like i never make it as fatal set off of this just cycle of feel and rising 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're 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 they make performance.

one is the primary function to sleep is learning and memory. if you don't sleep, memory simply doesn't happen. how much sleep bianca 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 women. what you learn and venue 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 no, i tried to avoid last minute cramming and all nighters. and if you feel like you can't manage, you're stressed out inside the talk to people usually trust like friends, family, or university counselors. don't hesitate to seek professional head. try to find out which of these to 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 cannot be trained. he's at the head. why has a psychologist who studies what helps people cope in moments of crisis? resilience plays a key role in their research. she and her colleagues even look into test subjects, brains. the term resilience refers to the ability to cope with challenges. scientists recognize 3 basic types of fuel and so i'm excited with us. and again, i brought to this who resilience bonzai with me because i think it nicely demonstrates the different ways that people react to adversity. to pop things skim

is that hopefully i can come to visit the mountain. the wind does life step bound 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 in one go 10, that schooled resistance from that keeps, keeps things. other people felt less well and may develop. symptoms of stressed have in terms of the when the wind dies down a little which is corporate generations, they manage to regenerate and stop growing normally again, taking a just look up on this. i did the cool the windsor fly started blowing. when done tony to put them as a sub type known as reconfiguration. cool, that's what i thought this is where the trunk changes that on top once i op on, sorry, i didn't do so well for awhile. it didn't get to the microsoft outlook, but then it managed to grow in a new direction. by an example would be 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, realized 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 well to see very specific activities and hoping 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 here, we look into the brain because we found that 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. again, it's responsible for thinking and planning this. and of course, these are also structures that can be trained. and because the ability can be trained isabella homepage and her team have found that the resilience outpatient clinic here, people can learn and develop specific resilience factors and courses,

or an individual coaching sessions for exam, well, 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, it doesn't have to say yours, of course no fill up to the phone, but it is positive like no one gets 3 life without some crisis. i. so you have to practice failure funding and we should teach people it's good to fail because you can learn from that, talk to them 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 as a thank you. so come on just that this week or question comes from jorge on the vehicle 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 threats long enough to encircles the clothes which weigh less than a bar of sorry, the, the europe and 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. prey, tangled up in spite of soak doesn't stand. the chumps. a single thread can contain up to 1500 strands. the material force is produced in the animal's optimum and was

the cold to spend the rest. or the spider slowly shapes its thread down to these glands. researches have been working for decades to replicate the price i saw sufficiently. ready 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 acts as a building block for spider silk. ready this rule material is then used to produce also official threads, even more or less to come, staples and then not tro counterparts. manufacturers warranty makes me cuss from spite of cell and coating. so medical implants, some cosmetic products also contain spine to 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 what you want to grab a taishan on the way that that is when did people begin getting high and laughing gas out drums boogie to the beads and what's the perfect king footboard find? find the on says guess 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
