How to get a child accustomed to mobile textbooks?

How to get a child accustomed to mobile textbooks?


Nowadays children are indulging in gadgets. They have started spending more time on mobiles, laptops, and tabs than on textbooks. In it, they watch videos, play games. Thus, the ability of students to focus on digital devices is weakening. Putting them in the classroom to read and write textbooks has become challenging. Generation Z (10 to 24 years old) and Generation Alpha (under 9 years old) have been born in a world where smartphones are setting their direction.


Today's children are so addicted to the stimuli from smartphone apps and streaming platforms that their attention is distracted from the classroom. This has added a big challenge to teachers. How to impart technology as well as traditional education to students?


Please note


The development of a child's brain is a complex subject. Over the past few years, researchers around the world have expressed concern about the adverse effects of smartphones and media multi-tux on concentration.


"The obvious evidence is that technology, social media, instant access to the Internet, and smartphones are harming children," said Dr. Jim Taylor, author of Raging Generation Tech.


His evidence has not been fully substantiated, arguments can be made against him.


"We're fundamentally changing the way a child thinks and develops his or her brain," says Taylor.


Lara Shad, a seventh- and eighteenth-grade (12- to 14-year-old) child in Philadelphia, says the average teenager can concentrate for about 28 seconds.


Smartphones have affected their brain development. And, the teacher has no idea how to relieve the student from this.


Lara Shad became a teacher in 2015. She has not received any training on how to teach a child born in the digital age.


The influence of technology is beginning to be seen in the curriculum and teaching available in traditional schools. Curriculum-based digital media for children has increased the use of apps such as Instagram and Snapchat, which are full of pictures.


Erica Swift teaches sixth grade at a school in California. She says, ‘It has become very difficult for students to teach long and complex lessons. Whereas earlier students did not mind reading such a lesson. '


Today's students do not easily understand complex and long lessons. They have to be broken and taught. Some children have stopped reading long lessons.


Transferring text to a device may not be as helpful. The problem is a bit deeper than just prioritizing the screen overprint.


According to Taylor, concentration is the gateway to learning anything. Remembrance deepens understanding.


"Without the ability to concentrate, a child will not be able to produce any information," says Taylor. They are not able to remember it. This means that they cannot interpret, analyze, synthesize, and critique it and cannot come to any conclusions about the information. '


Classroom of the future


When students cannot understand or memorize a long lesson, the teacher categorizes the lesson into shorter parts. The teacher thinks that a short lesson is appropriate.


Some teachers are also focusing on increasing students' concentration. One teacher also created a clam app to help students meditate.


Some teachers go and communicate with the students wherever they are. Such as YouTube and Instagram.


Asha Choksi, vice president of global research and insight at educational publisher Pearson, cites the example of a teacher who created a video from a scientific experiment and posted it on YouTube.


He showed the same video to the students in the classroom and started trying to remind the students of the lesson.


Students can be attracted to digital platforms if they are interested. Destler praises the teacher who linked the history of Nazi propaganda to cyberbullying.


He says, "If you add today's relevant thing to the compulsory curriculum, students will try to understand it more interestingly."


Educational platforms like Flipgrid, where students can share their videos by giving presentations, teachers can help students by engaging them.


Pearson's 2018 study found that students in Generation Z prefer to watch videos rather than books. After teachers, video is the second-largest source of information for them.


If the teacher adjusts the rhythm to the student's attention, it will be easier for him to focus.


Some schools have adopted platforms such as Google Classroom, where students and parents can monitor grader upcoming assignments.


The damage done to reading skills through technology has been compensated as much as it has been done.


Computer reading


This school in Lexia has a very interesting reading method. There, students are encouraged to participate in sports.


A separate group of students is formed based on performance. Successful students are assigned a previous level offline job. Backward students are given digital practice, as long as they do not fully memorize the text.


In the field of American education technology Is a global leader. In 2018, the Edu Tech company raised जु 1.45 billion. However, companies like Flipgrid and Lexia were hit by another country.


The Edu Tech industry has spread rapidly in East Asia. Newton, like the American platform, has expanded abroad. These companies are exploiting global interest in creating digital classrooms for students.


Mixed study


Teachers are adopting technology in the classroom. However, some studies have shown that traditional classrooms can be more successful.


A 2015 study by the London School of Economics found that when schools in Birmingham, London, Leicester, and Manchester banned phones in the classroom, there was an improvement in GCSE exam scores.


William Lam, a professor of neuroscience and author of The Learning Skills Cycle, points to a 2014 study. It was learned that students who write notes in the classroom can memorize any information more than students who write on laptops.


Lame considers it dangerous to break any text into smaller sections. According to him, going from one lesson to another immediately does not develop the student's memory. When the teacher starts a lesson, the student should memorize the lesson completely.


However, some advocates of technology point out that there are shortcomings in traditional reading methods as well. Therefore, he said, it would be more effective to move forward by mixing both technology and traditional education.


Katie Davis, an associate professor at the University of Washington School of Information, says, "I've seen a lot of discussion among academics in recent years about whether reading through lectures is like a relic and will disappear like a dinosaur."


Davis acknowledges that new media and technology teach new skills. However, the lecture has its own place.


Elizabeth Hoover, chief technology officer at a public school in Alexandria, Virginia, is working to improve the quality of education.


Hoover says teachers are just as indispensable today. And face-to-face conversations with teachers are still an important part of the classroom.


Hoover takes the side of technology where it is impossible to teach a lesson offline.


Economic initiatives


Shaad also says that some teachers rely on technology only because they do not have enough offline resources.


If more financial support is provided to the school so that the teacher can focus on the backward students, then there is no need for a program like Lexia.


Philadelphia teacher Sophia Date teaches social studies in the 12th grade. She also says that it would not be appropriate to spend money on technology instead of teaching.


"Efforts are being made to promote technology in the classroom," she said. The grant-in-aid organization is paying a hefty sum for tabs or laptops. But, they are not allowed to pay the salary of a teacher for one year. '


The date makes it clear that equal access to technology is important for low-income students, but it cannot replace management change.


Let's learn to think


Technology weakens some aspects of education, but it also empowers students.


"It's believed that young people are a little bit depressed, a little bit lazy, and they're being provoked by technology," says Choksi, who is associated with Pearson.


In fact, we need to reduce the role of technology in empowering a child's learning and learning.


To satisfy any curiosity, the students first ask the teacher and wait for the answer. Now they do not have such patience. They have started using technology to satisfy their curiosity.


At present there is no solution to any problem in the textbook or practice booklet, the solution is sought on YouTube or Google.


As information becomes more ubiquitous, success no longer depends on what you know.


Instead, it depends on the ability to think with subtlety and creativity. The irony is that digital media is undermining this skill.


In digital media, children have adopted new media. Now the teacher has to update himself with this. Now the teacher has to guide the students on how to benefit from the technology. Also, the teacher must fundamentally educate the student so that he or she can succeed in a world where he or she is constantly distracted.

Is your internet slow? Find out these reasons.

Is your internet slow? Find out these 5 main reasons


Customers never seem to be satisfied with internet service. This dissatisfaction is on the rise. Negative comments and abusive posts about Internet service providers are appearing on social media.



In fact, the Internet is slow for a variety of reasons. Every user needs to be aware of this. Today we are going to discuss the main reasons why broadband internet is slow.




1. Your WiFi offers extensive coverage but, it can weaken your connection performance. Distance reduces your WiFi signal and penetrates the ceiling and walls of the house, causing problems for the WiFi signal.



To get rid of this problem you can connect your device to your router using an Ethernet cable. Test the speed now and you will be happy with the result.


In addition, you can improve WiFi performance by placing the router in the center of your home. It is better to keep it in an open, downward position. But never hide it in a narrow place.



2. The internet is for sharing and use. So you share it with your friends and family. But while sharing, don't forget that Wi-Fi has its own limitations on how many devices it will flood.


When your broadband is being shared with many people, then this internet is being used for various purposes. Such as video streaming, online gaming, etc. It consumes a lot of bandwidth. As a result, the overall performance of WiFi is affected.


Test your broadband speed two to three times a day. You will find that when very few people are using the internet, then your net is working at a very fast speed.


But the fiber broadband package can support many connections well. It works better than standard broadband ADSL. It does not harm the speed and overall performance.


3. Not only the distance but also the location of the router is another factor that affects the connection performance by affecting the signal of your WiFi. Apart from this, the distance between the nearest telephone exchange and the active street distribution cabinet is another factor.


At these points, your information can be accessed online or uploaded to the Internet. The farther you go from these points, the weaker your connection becomes. A quick web search will show you the nearest telephone exchange location.


If you are a customer of Standard Broadband ADSL, request line speed as estimated by Fiber Broadband Provider. From this, you can see the current speed of your broadband. The technology of fiber optic broadband is that even at long distances, its speed is always very high.


4. If your WiFi password is secure, a neighbor can't steal it. But you are sharing the network infrastructure. Which also gives coverage to your road and surrounding area. The technology is the same as sharing the Internet with your family. But the Internet infrastructure that is shared with neighbors has a lot of potential on a large scale.


When there are more people online in your area or on the street, the demand for the network increases exponentially. In this case, the speed may be disturbed.


Some broadband providers have direct control over network usage. This control limits Internet activity. Which allows other users to access the Internet equally. This is called traffic management. It helps all users to consume the internet equally.


5. Sometimes the main reason for your sluggish broadband can be your service provider. Your provider's traffic management policy also controls your usage.


If so, you do not have a solution to this problem. In that case, go to your provider and request a possible solution. Even so, if you are not satisfied with the old service provider, you are free to go to another service provider.


Why isn't the internet speed as high as the service provider says?


 Customers never seem to be satisfied with internet service. This dissatisfaction is on the rise. Negative comments and abusive posts about Internet service providers are appearing on social media.



But service providers say the slow speed of the Internet is not their only weakness. In a virtual interaction held by Technology Journalists Forum (TJF) Nepal, they said that the internet could be slow due to problems with bandwidth, various servers, and mobile apps.



During the interaction, Vinay Mohan Saud, CEO of Subisu Kewal Net Pvt.



"Customers' complaints are justified. Internet service providers may offer more Mbps than they can afford due to fierce competition, but many of the problems are not just our fault. We are just a pool between the consumer and the server or app. If there is a problem in one of the three parties, the internet will be slow, but we will be the only ones to be abused, 'said CEO Saud.


Saud said all service providers were working to address customer grievances and that their initiative alone would not be the answer. "Sometimes there is a problem with platforms like Facebook, YouTube, and Tiktak. But consumers blame the Internet service provider. We can't solve the problem of Facebook, Tiktak, YouTube, 'he added.



Similarly, Vinay Bohora, Managing Director of Vinet Communications, said that the complaints of consumers about slow internet will never end. "The internet is slow now because of the ticking. Another similar app will come tomorrow. There will be many internet consuming sites. Even then the internet may be a bit slow. Therefore, its grievances cannot be fully resolved. We will continue to reduce it, 'said Bohora.


At present, 80 percent of internet consumption is in video and it is on the rise, so how to provide quality internet in the coming days is a challenge, says Bohora.

"Even though we have a lot of internet consumption, we don't have the infrastructure and equipment to manage it. We also have to import bandwidth.


We buy from India. If there is a problem, the internet will slow down or shut down in Nepal. On top of that, Nepal's geographical remoteness is also a problem, 'he said.


Managing Director Bohara hoped that the criticism of internet service providers would be lessened if the servers and exchanges of big platforms could be kept in Nepal. Bohora admits that sometimes customers may not get quality internet due to unhealthy competition among internet service providers in the name of competition.


"We have no control over bringing in servers. We are also at their mercy. There is a lot of content politics in it, 'says Bohra,' and again the content owners don't give us money. But we have to adjust the quality of their content. Content comes from Uta but we get abused when the content is buffered. '



The problem is exacerbated by corona

The speed of the Internet has been further hampered by the fact that people have to stay indoors due to lockdowns and bans on coronavirus prevention and control. According to Vinay Mohan Saud, CEO of Subisu Kewal Net Pvt.


He informed us that the demand for 22 to 25 GB bandwidth has increased only after the lockdown. ‘Before the lockdown, a customer used to consume about 300 GB of the internet in a month.


At present, 500 to 600 GB is being consumed. The Internet may have been slowed down by most users. It's good that they understand that, too, "said CEO Saud." Another problem is the cost of customs. WiFi congestion is on the rise. The number of internet connections is on the rise, 'he says.' Customers need to have a good device for WiFi. It also improves the customer experience. '


After Corona, Google grew by 37 percent, Facebook by 47 percent, and TickTack by more than 75 percent, he said. Saud also urged people not to do so as the internet will be slow when the app or server used for entertainment is running in HD and high capacity.


Similarly, Vinay Bohor, Managing Director, Vinet Communications Pvt. Ltd., said that Internet service providers are facing a bigger problem after Corona. "The demand for the internet has grown so much that our equipment is in a state of disrepair. In such a case, it takes time to bring the goods on the charter ship coming from abroad. That is, manpower is not available at the time. After Corona, we are in more trouble, ”said Bohora.


Not just by blaming service providers: Anandaraj Khanal, a telecommunications expert

In a virtual interaction with TJF, telecommunications expert Anandaraj Khanal said that one should be satisfied with the services provided by Internet Service Providers (ISPs) amidst many shortages in the country.


During the epidemic, developed countries have taken many other initiatives to improve the quality of the Internet, including increasing bandwidth, but Khanal accused the Nepalese government of doing nothing but instructing consumers to get discounts.


‘The quality of the internet is not just in the hands of the service provider. The Internet is a great system in itself. The government, regulators, and consumers have a long way to go. If we understood the plight of the service providers, we would not have abused the service providers, 'said Khanal, a telecommunications expert.


Stating that the ISP has to travel here and there for days to pay for bandwidth abroad, Khanal said that the government has only given instructions but has not paid attention to policy and practical work to improve the quality.


He said that the service providers have been providing the content including the routers, adding that the internet speed has been reduced due to the low-quality routers.


He says there are only two ways to increase internet service as per demand, the first is bandwidth and the second is infrastructure.


He cited the fact that Europe saw the problem of infrastructure constraints in order to manage the growing Internet consumption during Kovid's time, adding that OTT had to reduce quality and adapt its services to its infrastructure. Similarly, the United States has also added unused frequency service providers, but in Nepal, there is a lack of flexibility, he said.


In addition, many devices are connected at home. But he also discussed the unreasonable expectation of the service seekers that we are looking for 10 Mbps on the same device.

Nepal has pushed back 22 places in internet speed, the situation is the worst in two years

 Nepal has pushed back 22 places in internet speed, the situation is the worst in two years


Nepal's position in the global broadband speed league has slipped. Nepal, which was ranked 128th in the world last year, has slipped 22 places to 150th position this time.



At the same time, Nepal's internet speed has reached the worst level in the world rankings for the past two years. Earlier, in 2018, Nepal was ranked 144th (out of 200 countries). Nepal jumped 16 places to 128th last year (out of 207 countries).




But in 2017, Nepal's situation was even worse. Out of 189 countries, Nepal was ranked 169th. Although Nepal's place in the world rankings has slipped, internet speed is improving.



In 2017, 2018, and 2019, the download speed of broadband internet in Nepal has increased from 0.97 Mbps, 2.36 Mbps to 3.62 Mbps and now it has reached 5.22 Mbps. However, during the lockdown period, the speed decreased to 4.52 Mbps.


Compared to the fastest internet in the world, Nepal

Before the lockdown in Nepal, the average download speed of the Internet was 5.22 Mbps. It took two hours, 10 minutes, and 52 seconds to download a five GB movie.



Liechtenstein in Western Europe has the fastest internet in the world. Where the average download speed is 229.98 Mbps. It takes only 2.58 minutes to download a five GB size movie.


The next top ten countries with fast internet are Jersey, Andorra, Gibraltar, Iceland, Switzerland, Hong Kong, and Monaco.


The average internet download speed is 218.37 Mbps, 213.41 Mbps, 183.09 Mbps, 118.05 Mbps, 116.88 Mbps, 110.45 Mbps, 105.32 Mbps, and 104.98 Mbps respectively.


Neighboring Nepal

Of the 27 countries in Asia, Nepal's internet speed is ranked 18th. The top five fastest internet countries in Asia are Hong Kong (105.32 Mbps), Singapore (72.75 Mbps), Taiwan (54.77 Mbps), Japan (54.77 Mbps), and Malaysia (46.82 Mbps).


The average download speed of Nepal's neighboring countries is 13.46 Mbps in India, 20.73 Mbps in Sri Lanka, 5.88 Mbps in the Maldives, 3.24 Mbps in Bangladesh, 12.58 Mbps in China, 2.09 Mbps in Pakistan, and 4.62 Mbps in Bhutan.



Where the world's worst Internet speed

When it comes to fast internet speed, very slow internet speed is not discussed. In 71 out of 221 countries of the world, the internet is running at a slower speed than in Nepal. The worst internet in the world is in South Sudan.


Where the average download speed is only 0.58 Mbps. It takes 19 hours and 31 minutes to download a five GB movie. Earlier, the top five countries with slow internet were Yemen (0.65 Mbps), Turkmenistan (0.74 Mbps), Equatorial Guinea (0.75 Mbps), and the Syrian Arab Republic (0.76 Mbps).

Build a prototype of a self-charging battery that is thousands of years old

Build a prototype of a self-charging battery that is thousands of years old


 How about not having to charge your smartphone or laptop? Everyone thinks that Anand would have been able to use it once he bought it. But the battery with so much capacity has not been made yet.



But the American company NDB has come up with a prototype of thousands of years old self-charging batteries with the courage to prove one possibility. The company has been developing and manufacturing nanodiamond batteries, which are clean and green environment friendly.




NDB has successfully tested the concept of its nanodiamond battery. One of the tests was performed at the Lawrence Livermore National Laboratory and the other at the Cavendish Laboratory at Cambridge University.



In both tests, NDB's battery technology managed 40 percent of the charge. The latter result is a huge improvement over the 15 percent charge collection efficiency of Standard Commercial Diamond.


This exploration by NDB will create a new proprietary nanodiamond treatment. This will help to make a battery by extracting a very good electrical charge from the diamond.



The basic purpose of this development is to commercialize the battery life up to a maximum of 28,000 years. It is made from carbon 14 nuclear waste wrapped in synthetic diamonds.


This battery does not emit carbon while working. It needs open air to work. It is technically a battery as its charge can be used.


The one-time charge is longer than the lifespan of the device. So it is also a kind of charge-free solution.


NDB expects the battery to be a usable power source. So that even ordinary people can use it.



The NDB aims to use it on aircraft, EVs, trains, and small devices such as smartphones, small industrial sensors that can be worn.


The company is currently working on a prototype of the first commercial battery. The company is preparing to make it public by next year.
