Check it out !? "New Corona" and "Plastic shopping bag" ... January 27, 21:09

Current affairs that are asked in the junior high school entrance examination.

What is the number one news that private junior high school teachers want elementary school students to know?

Then, I interviewed a major cram school about how to check the news that I can do now.

Keywords that are expected to be asked

Keywords cited by major cram schools as measures for junior high school entrance exams include "new coronavirus," "telework," and "Tokyo Olympics and Paralympics."


Of these, we will look at the prediction problems of the new coronavirus.

Challenge the prediction problem

Problem In


2020, sales of electrical equipment products increased while sales of restaurants and accommodation facilities often decreased.

Why did sales of electrical equipment products grow?

Write what you can think of as the reason.


(Waseda Academy forecast problem)

I asked the instructor of the cram school what to think about this problem.


This is Yoshihiro Aizawa, in charge of social studies at Waseda Academy.

Where is the intent of the question?

Mr. Aizawa


"The new coronavirus is not only anxious about health due to the spread of infectious diseases, but it also involves society and always has a background. It is more about corona than knowing about the new coronavirus. I would like to ask what you think of other things like this. "

Last year, due to the impact of the new coronavirus, sales at many restaurants and accommodations plummeted.


On the other hand, sales of electrical equipment products have increased.


Then, it is said that the point is whether or not you can reasonably answer what kind of product was sold.

Let's compare the two things

Mr. Aizawa


"As is the case with Japanese, it is important to be able to handle the idea of ​​contrasting the two things well. The problem is that all restaurants and accommodations go out of the house. On the contrary, sales of electrical equipment are increasing. I think that it should be the opposite reason for one reason. I will start exploring from the point that "do not leave the house" is the keyword. In other words, the progress of remote work has increased the number of people who work from home. "

Did you understand this?



An example of the answer is ...


"Because many companies have introduced telework, the demand for personal computers has increased."

Mr. Aizawa's advice was that you should appeal that you can use the word "telework" and that you know "what is an electrical equipment product".


And it is said that the ability to understand and think about the background of things is required rather than just memorizing words.

Mr. Aizawa:


"Take it to a state where you know it, not know it. I'm pretty proud of knowing it early. If you say," I said multiplication tables in the first grade of elementary school, "I'm a hero. In the third grade of elementary school, everyone can say. Early means that the advantage disappears soon. Rather, it is overwhelmingly advantageous in the long run to know a wider area with deep interest and try to master it. It's a guy who wants to go as far as he can go. I think it's better to go from that perspective. "

News that elementary school students want to know

The next issue is the theme that is ranked first in "News that private junior high school teachers want elementary school students to know" (according to Sapix Elementary School).


That is "paying for plastic shopping bags".


The charge for plastic shopping bags began in July last year to solve the marine plastic waste problem and global warming.

Problem


shopping bags There is also dissent in that it has been excluded from the charge for which the raw materials of plant origin formulated more than 25%.

Explain what the reason is.


(Sapix Elementary School Forecast Problem)

Some of the eco-friendly plastic shopping bags can be free of charge, and there are opinions against it, asking why.



Click here for plastic shopping bags that can be used free of charge.

▽ "Thickness of 0.05 mm or more" This is because it


can be used repeatedly and is difficult to be disposable.



▽ "A product containing 100% marine biodegradable plastic that is decomposed in the


sea

" The

reason is that it is unlikely to lead to the problem of marine waste.



▽ "A mixture of 25% or more of plant-derived biomass materials and biomass plastics"

I don't think even adults know this exactly, but I asked another cram school instructor what to think about this problem.


This is Shigeo Tamai, who is in charge of social studies at Sapix.

Mr. Tamai


"Biomass plastic is considered to be an environmentally friendly material because it does not increase carbon dioxide when burned. The point is" what is the remaining 75%? "It is the same as conventional plastic raw materials. If you know, the amount of plastic waste derived from petroleum will increase or will not decrease. "

An example of the answer is ...


"If the remaining ingredients of the raw material are derived from petroleum, it will still be marine plastic waste, and if it remains free, it will be disposable."

Then one more question!

Problem


Select one of the approximately 9 million tons of plastic waste that is discharged in Japan each year that is closest to the amount occupied by plastic shopping bags, and answer with a symbol.


A 200,000 t


1.3 million tons


cormorant 2,800,000 t


e 4 million tons


(Sapikkusu elementary department expected to issue)

Mr. Tamai


"The answer is 200,000 tons. When I asked the children about this during class, they said,'Is there only that?'" "Is the charge really reducing plastic waste? Of course, you have the question, "I think it will be important to cherish that question in order to proceed with this kind of study."

What do you want children to think about this issue of plastic shopping bags?

Mr. Tamai


"The fact that this amount of plastic waste is generated means that we are using a large amount of plastic products. When it comes to how to reduce plastic waste and how to replace it, it may be a problem that cannot be answered. No. Perhaps the aim of the junior high school teacher is the message, "There may be many unanswered questions in the future, but it is important to think hard about them." "

Mr. Tamai said, "I want you to cherish the moment when your child is interested, not what happens at home. Adults are busy every day, but when the child is interested in something, it's okay to pretend to be interesting. If you respond to that, it will give you an opportunity to deepen your interest. "


It's important not to kill the buds of interest.


All of the examinees, please be in good physical condition and go to the actual performance.
