Homeschooling

The concept behind homeschooling is really quite simple: Parents accept total responsibility for the education of their children rather than transferring the bulk of this responsibility to a public or private school . In practical terms, this means that the home becomes the center of a child’s education , rather than a school . Parents , who have a deep interest in their children based on love,become the primary educators for their children.Homeschool parents carefully guide their children through their mental, emotional, and physical development.The parents choose an educational path for their children based on each child’s personality and gifts.

Public schooling is free, and each child is guaranteed to have a free and appropriate education. There are public schools all over, making it easy for your child to get there, plus there is usually transportation, so you don’t have to do anything to get your child to school except to get them out to the bus stop on time.The kids also get a lot of socialization which will help in their later lives. They will encounter a lot of different personality types.However,public schools are geared to teach the average student. Which means gifted kids get bored and kids who are struggling keep getting left further and further behind.

Some benefits of homeschooling are that homeschooled children get the individualized education that their parents want them to . The education is totally geared around the child and will work towards their strengths and help them with their weaknesses . The parents get to spend a lot of time home with their kids , so while the kids are being educated they are also bonding with their kids . The gifted kids get to work as fast as they can , while the children who are struggling get to spend all the time they need to stay caught up .

Some disadvantages of homeschooling are that that the parents of the child in question has to give up a lot of their time to teach the child . Another is the lack of facilities , there is no way for a standard house to be as well equipped with learning materials as a standard school is . There is also the question of the costs , it costs a lot of money to get all of the textbooks , worksheets , and other learning materials .

Those were some of the reasons why I think homeschooling is a very good idea .

Virus

This flu season has been especially bad , around 31.5 people out of 100000 in the USA have been hospitalized due to it . Flu vaccines saved an estimated forty thousand American lives between the years of 2005 and 2014, but they are not good enough.The vaccine used during the 2017-2018 flu season was only 43 percent effective against the predominant influenza A H3N2 strain .

 

Flu viruses are classified by the numbers after the H and the N . The H stands for Hemagglutinin and the N stands for Neuraminidase . This year’s H3N2 is especially bad because of two reasons . The first reason is that H3N2 mutates especially fast . Regular flu viruses mutate in around 1 year , but H3N2 mutates in half of that time . Because of that , in the 8 months it takes to make the vaccine most likely the virus will already have mutated . The second reason is that it does not work well when it is grown in chicken eggs which were the most used source of vaccines for nearly 90 years .

 

There are 4 types of vaccines namely Live-attenuated vaccines , Inactivated vaccines , Subunit vaccines , and Toxoid vaccines . Live-attenuated vaccines are made of weakened forms of the disease in question . Inactivated vaccines are made from dead viruses and only give limited protection against them , which is why you need to get booster shots every once in a while . Subunit vaccines are made of pieces of the virus which gives your body a very strong immunity against the virus but does not have the same risk as live viruses . That makes Subunit vaccines much more safe to give to people who have immunodeficiencies or people who have long term health issues . Toxoid vaccines teach the immune system to fight off a toxin the virus produces instead of the virus itself .

 

Hopefully this horrible flu season will be over soon . Almost for certain , better vaccines will be created and maybe sometime in the future , most deceases will be eradicated .

AI

Artificial intelligence is the intelligence that is displayed by machines , in contrast with the natural intelligence (NI) displayed by humans and other animals. In computer science AI research is defined as the study of “intelligent agents”: any device that perceives its environment and takes actions that maximize its chance of success at some goal .

One way that AI is created is by the genetic breeding model . In this model there is a builder bot and a teacher bot . In the start the builder bot just randomly builds bots and those bots are sent to the teacher bot . However the teacher bot cannot really teach because if the teacher bot could do the problem it was designed to teach then it wouldn’t need to teach it . Instead it just tests each of the bots and sends the best ones back to builder bot . The builder bot copies the successful ones with some tweaks and the process is repeated .

 

Some examples of AI are personal assistants like Siri , and Cortana and others such as Alpha Go Zero . The personal assistants usually learn from human conversations or past conversations with other personal assistants . Alpha go zero is especially interesting because it never got input from humans . Meaning that it did not get examples from its creators beforehand but instead just played games against itself over and over until it eventually got so good that it beat every other version of alpha go that came before it .

 

Some people think that in the future probably there will be robot servants that are equipped with Artificial Intelligence and humans will not need to go outside anymore . Or as some very intelligent people like Elon Musk think , Ai might turn evil and destroy humanity . I am more optimistic about this topic so I think that Ai will probably increase the standards of life even further and as a consequence humans will become more relaxed .

Bitcoin

The cryprocurrency known as Bitcoin is the first decentralized cryptocurrency which means that it is the first payment system without a person or people running every transaction . Bitcoin was created by an unknown person or group of people under the name Satoshi Nakamoto and was released as open source software in 2009 . Bitcoins are created as a reward for a process known as mining in which people known as miners use big computers to solve an encryption problem that I will get more into in the next paragraph .

 

Bitcoin is a ledger that is kept track of by miners . Miners keep track of groups of transactions called blocks . Miners use special software on their computers that sift through huge numbers of possibilities to crack an encryption scheme known as RSA256 . Around every 10 minutes one of them gets it correct and their block gets added to the end of the ledger . Every transaction in Bitcoin has the Bitcoin address of the sender , the Bitcoin address of the receiver , the amount which are all encrypted with the sender’s secret key .

 

One of the risks associated with Bitcoins is that they are very volatile . What this means is that the price of Bitcoins can change very drastically . Sometimes they can lose or gain 25 percent of their value in minutes ! Another risk is hackers . One way that hackers can affect Bitcoin is by stealing online Bitcoin wallets . Another risk is when hackers hijack the Bitcoin exchanges . These Bitcoin exchanges are supposed to exchange Bitcoins for real money but if a hacker hacks it then they can get all of the Bitcoin for themselves .

 

I think that in the future Bitcoin or some other decentralized cryptocurrency may become the norm . What I mean by that is , I think that in the future maybe everybody will use cryptocurrencies instead of real money to purchase items in the real world . Although it may just turn into a place where hackers exchange digital money and information . One reason that I think this may happen is because on Bitcoin you are anonymous and usually hackers like being anonymous because then they cannot be persecuted for their crimes .

My Third Essay

Topic: Do you think that sending rockets to space is a waste of money?

 

Some people think that sending rockets into space is a waste of money. In this essay I will write about the reasons why I think that sending rockets is not a waste of money .

Firstly in the short term , rocket launches create lots of enthusiasm for STEM ( Science,Tech , Engineering , and Math ) fields . This enthusiasm makes more people want to go to universities . When people go into higher learning they get better jobs and therefore get more money . And once they get more money they can support their families better than if we just gave the rocket budget to them from the beginning .

In the long term the quality of life could get better because some of the technologies we use in the space industry can be used in regular life too . One of the examples are cordless drills which were developed by NASA for collecting moon samples . Cordless drills are good because they can be used any where and they don’t give you the risk of tripping over or tangling the wire .

Those are the reasons why I think that sending rockets is not a waste of money. I hope you agree with me and think that sending rockets to outer space is a worthwhile activity.

My Second Essay

First Draft:

I think the internet is a very awesome invention!

My first reason is that it helps us to transfer information much faster. One example of this is that you don’t have to go to physical stores to shop anymore.Now with digital shops like Amazon in the rise probably in the near future no one has to go out of their house to buy stuff.Another example is Banking. In the olden days people had to carry all of their money in their wallets,but now people can deposit their money online and even use purely electronic currency like Bitcoin.

My second reason is that the internet gives us more options for entertainment. Before the internet kids only had 2 major sources for entertainment. Namely Books and TV.With the internet you could watch whatever whenever. Meaning that you can watch anything anytime.

Another advantage you get with the internet is Social Media. What I mean by that is if you have a pal on the other side of the world and you wanted to contact them without calling them , you can use services like Facebook to message them.

Those are the reasons why I think he internet is a very wonderful invention !

 

Second Draft:

Around 40 years ago almost nobody imagined that a thing known as the Internet would permeate most parts of life.Whereas in the modern age , life without the internet is almost unimaginable.I will be writing about my reasons for why I think the internet is awesome below.

My first reason is that it helps us to transfer information much faster. One example of this is that you don’t have to go to physical stores to shop anymore.Now with digital shops like Amazon on the rise probably in the near future no one has to go out of their house to buy stuff.Another example is Banking. In the olden days people had to go to a physical bank to do all of their banking.But now people can do most of their banking from their computer.

Secondly, the internet gives us more options for entertainment. Before the internet kids only had 2 major sources for entertainment, namely Books and TV.The downside of books are that you have to go to a library or a bookstore to get them and the downside of TV is that you can only watch what is on right now.But with the internet you could watch whatever whenever. Meaning that you can watch anything anytime.

Another advantage you get with the internet is Social Media. What I mean by that is if you have a pal on the other side of the world and you wanted to contact them immediately , you can use services like Facebook to message them.

The last thing that I am going to talk about is how the internet affects education.Before, students had to go to a school to take a course.With the internet anybody can learn any course from the comfort of their home with the help of video lessons.They can also rewind if they don’t understand a topic and ask online communities questions.

In the near future most scientists believe everything will be connected to the Internet. From your house keys to your curtains and from your car to your kitchen table, everything will be linked to this “Internet of Things”.The internet has had a big influence in our lives and will keep impacting us forever.

My First Essay

Topic:Can Textbooks teach us more life skills than fiction can?

 

My opinion is that textbooks can teach us more about life skills than fiction can. (the first paragraph can be more smooth and interesting, try harder next time)

In my opinion,fiction is about imaginary events, people, and things.While textbooks are like cookbooks,how-to books , and other learnng books in general. ( Not really consistent, when you talk about textbooks, you use examples not definitions like in fiction)

An example of fiction is How To Train Your Dragon. It is set on earth during the viking times and it features Dragons.An example of a textbook is Introduction To Number Theory which is a textbook that teaches you the fundamentals of number theory. (Very good example, also very nice to highlight book names, maybe try to elaborate more)

The reason why we learn from textbooks at school is because it teaches us the skills needed to get the job you want.But if we only learned from fiction we would only know how to defeat fictional bad guys like Sauron .But those kinds of people do not exist in the real world so that knowlege is kind of useless.(Who is Sauron?? try to be more specific, more details please 🙂

Those are the reasons why I think textbooks can teach us more life skills than fiction can. (extractly same as the first pharagraph)

Grader comments are in Green :

4.5/6

I think the essay is very well organized and clearly stated, the writer successfully used good examples to support his opinion, as well as good conparison between two subjects, however, the essay is little bit toooooooooooooo  skinny, how about  more explanations ,details and reference next time

I agree
