not resigned to make up your own mind. dw, made for mines 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 to probably

originally rose from the need to reflectively latch on to a mother, animals for the pin. so graph 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 4, and to right. and this 2nd grade class and the small but very in 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. our side, in 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, on new ideas. my eye is

a researcher in an institute dedicated to the topic. she's here today to observe how individual children use their hands when writing how did they hold the pen? do they write fluently, or do they tense up? it should ivan down. i mean, really learning to rise to is learning to move comes for because when we talk about him by saying, we're not just talking about finished laughter. but the movement that leads to handwriting 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 different surveys have shown that children are losing interest and writing. now the a 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 diarrhea. let you play 5 months, at least at least half of all boy you said 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 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 and i yeah, this looks on this, 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 teachers come encouraged us even more in charge for this, i have done enough that despite the for that so either 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. 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 to play with the hands of it and having some fun. but the times that 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 digital age has given rise to many programs aimed at 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'll turn one out in seconds off. i'm not 100 percent, correct, or stylistically perfect. even so a i is posing a tricky dilemma for schools. this elementary school in switzerland, chips and 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 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. because works on different tasks. one is to us t v 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 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 always get to certain questions, it doesn't really work properly. get this stuff up is fairly 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 left the dogs and then it said i was adult. it's good for you to realize that you can make a new version and always improve and change for this month and then the old amount thanks chuck 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 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 a 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 this must 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 talk g p t can spit out solutions that help the students solve most problems on that right in the past. and the system that responds to individual needs, the position comes close to it. but 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't actually solve the problems for you often lose the house i left nice of us. so 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 is clear that 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 of math teacher. you will know, suppose the guy sees great potential and i, even if it caught the mouse very well,

he's especially happy to have some multiples in the run up to final exams on the 15th. 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 to also in that way it's sensational. maybe it's in a fault 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 insoluble minds. and if you understand that, then you can use it efficiently, but suffice 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 in 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. whether it's good to him by popular e style or tech structure. students had learned how to write good prompts, the entries in 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 because i also think that text is better now. do the structure is generally better than the speech path. 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 for additional calls as 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 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, 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 stress head students all over the was a number of seem to have increased. for example, 2 out of 5 college students suffer from anxiety, one and 3 even from depressive. some tim colbin 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 adding in dominion 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 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 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

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, this is feeling better now this before the test that's nominated. but besides from being well, professor, another important factor 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 it's like, i never make it a sales set off of this just cycle of feel and driving stress comments. 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 being and 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 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 friends, listen to good music or use social media, especially in the 2 weeks before an exam. a good study plan has certainly not tried to avoid osman is coming in all night to us. 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 these to help you. 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 that be trained? he said belle, it hadn't why? she was a psychologist to studies what helps people co been moments of crisis. resilience plays a key role in their research. she and her colleagues even look into test subject brains. the 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 the list 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 step bound latrice ways. but if you look at the trunk remains every time and stuff and stuff because i worked with some people, the stress bounces off and one pen probably normally against taking a just look up on this i did before the wins of life started blowing when done get sony to put them as a said type known as reconfiguration to have on file. this is why the trunk changes that onto the bonzai op on. so i didn't do so well for a while, really it didn't get to the microsoft, but then it managed to grow in a new direction and i'm on 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 brought to requests in a matter of speaking. hey mike, for instance, realize what's really important to them in their lives and strike housing completely new direction that i'm familiar with. it's like they might quit that job, i hope to see very specific activities and 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 resilient you are can change over the course of your life. how do i send her team want to understand exactly how it works . vehicle that in this case yeah, we looked into the brain because we found the tim resilience people some struck to the fact that developed in the brain to play the move in to connect to it. and the next 40 i'm lucky and mikaela the son to for processing a motion to the tool. so another important structure of the prefrontal cool toxic in the full brain it's, it's responsible, sustained king. i'm planning this and of course these also structures that can be trained on and because the ability can be trained isabella homepage and her team have founded a 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 on hold for say

years of course no fill up to the phone but it is part of life. no one goes through 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 energy k from el salvador the. what can we learn from spiders? the spiders and most of builders that

help a lot to teach helps the they can produce so many times find the human thread low enough to encircles a globe which weigh less than a bar of sorry, the, the european gotten spider. we've subscribe from several different types of threats . spider silk is free of bacteria and delta. 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 has produced in the animal's optimum and was the cold spin of wrecked. the spider slowly shapes its tread down to these clones. researchers have been working for

decades to replicate the price i saw sufficiently. ready ready ready to do the pay for so then they transplanted it into bacteria. the bacteria modified in this way. stop turning out the protein acts as a building block for spiders soak. ringback this rule material is then used to produce also special threats, even more or less to come, staples and then not tro counterparts. manufacturers 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 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 i'm take talk. what you want to gravitational way is that that is when the people begin getting high and laughing gas out, the drums boogie to the beads. and what's the perfect kit? 4.5, find beyond says gets her c w science. oh, 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
