The following article comes from Han Dad in the United States, the author is a science and engineering man

   Many parents who are looking for a school for their children in the United States will choose private, and some feel that public education is more in line with their own educational outlook. What is the difference between the private and the public? The experience of the siblings in the article gives a particularly detailed example......

Text丨Science and Technology Male Han Dad Editor丨Yuan Zixi

Yesterday, when I picked up my daughter from school, the moment the little girl walked out of the classroom, she looked a little melancholy.

"What's wrong with you?", I asked her.

The younger sister didn't speak, but took out a test paper from her school bag.

I subconsciously glanced at the score in the upper right corner.

Uh, that red number makes my heart tremble, what? It's only 88 points?

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

I was taken aback, and instantly I knew the reason why my daughter was unhappy.

It turned out that I didn't do well in the exam!

Han Han on the side laughed when he saw it.

"In the 2nd grade exam, it's only 88 points!", my brother began to show off "relying on the old and selling the old", "When my brother was in the second grade, he scored 100 points every time!"

Then he leaned his head to his sister's side and smiled slyly: "Isn't my brother very powerful?"

But my sister didn't eat his set, turned her head to the side, and didn't speak angrily......

I couldn't stand it anymore, so I hurriedly stopped Hanhan's provocative behavior.

"You take a look at my sister's test paper first", I put the test paper in front of Han Han, "See how many questions you can do correctly?"

"easy!", the son took the test paper nonchalantly, but after 1 minute, his face changed, "Ahh???h

His face was incredible......

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

My brother is in the 10th grade this year, my sister is only in the 2nd grade, and the difference between the two little ones is 8 years old.

There are also differences in the paths of the two children to school.

back then

When my brother was in the second grade, the child went to the public school at his doorstep and went to it for 4 years

Their public school ranking is quite high, with a full score of 10, which is much higher than the average public elementary school in California.

The following table shows the school's ratings, and you can see that whether it is math, English, or science, the teaching scores are far ahead.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

After my sister was born, we moved, and there was no good school at home, so we changed her to a private school.

I originally thought that the difference between public schools and private schools was that the teaching environment was better.

But wait until I compare

The teaching content of my brother and sister is really very different!

And this is also the first time Hanhan has looked at his sister's exam papers, and it also shocked him fiercely!

My sister took a science class in this exam, and they studied mechanics in physics in this unit.

The following is my sister's workbook, which teaches "Balancing Forces", which is "the balance of forces".

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

It will teach what gravity is:

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

Teach what contact and non-contact forces are:

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

What is the Balance of Forces:

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

What is Magnetic Force:

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

And these contents were never learned when Han Han was in public school.

I remember that when Han Han was in the second grade, their public school also had science classes, but their science classes were mainly activity-based.

For example, take your child to observe the leaves of a tree and create a picture like the one below.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

Or that homework paper cut and paste, so that children understand what the five senses are.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

Like my sister who studied mechanics in physics, they had never been involved. However, it is not until the 6th or 7th grade, when you officially start to learn physics, that you will be exposed to these contents of mechanics.

Contrast

Year 2 in public and private schools

teaching content,

My sister really learned many times deeper than my brother back then!

Hearing me say that my sister was more difficult to learn than he was back then, my brother was still a little unconvinced.

So I asked him to try to do his sister's science paper and see if he could do it?

After reading a few questions, my son couldn't hold it anymore!

 1. The first part of the examination paper  

The first part of the exam paper is:

Explanation of terms.

The teacher gave several mechanical terms, such as "force", "gravity", "repel", and "unbalanced force".

Then some English descriptions were given, and the children's task was to fill in the corresponding English descriptions of these professional physics terms.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

For example, what does the "balanced force" mean?

其中的解释是“multiple forces of equal strength acting on an object”(多个相同大小的力施加在同一个物体上)。

And this is the explanation of the term "balanced force".

In order to get this part of the question right, the child must get it right

Every English concept of mechanics

, you have to know very well.

 2. Part 2 of the examination paper  

This is followed by the second part

True or False.

This section is also challenging, as it lists some statements about mechanics and allows the child to judge whether they are true or wrong.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

This part is quite challenging, and many of the descriptions are very confusing.

比如说“Magnets can attract all the metal objects”(磁铁能吸引所有金属物体)。

Many children answer this question incorrectly, they think that magnets can attract iron, and they take it for granted that they can attract all metals, but in fact, this is a concept that is not clear.

This type of question is to allow children not only to memorize concepts, but also to fully understand the meaning behind each mechanical concept.

 3. Part 3 of the examination paper  

And then there's the third part,

Look at the picture and speak.

This picture is actually to let the child draw the mechanics in the life scene.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

You see there are a lot of pictures in it, some are children pushing cars, some are falling freely with small balls in their hands, and some are a group of children in tug-of-war.

Then the teacher asks the children to mark the direction of the force and what type of force it is.

For example, the question that her daughter answered incorrectly, she was deducted 1 point for this question because the answer was incomplete.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

This is the scene of a tennis ball falling freely, so the child has to answer that there is "gravity", which is "non-touching force".

There are also two terms missing, one is "pull" and the other is "attract", both of which denote the gravitational pull of the earth.

 4. Part 4 of the examination paper  

The last part is the hardest, and it is

Q&A questions.

And this part of the question and answer is:

The question is where the daughter lost the most points, losing 10 points.

How are the quiz questions set up? It's pretty interesting.

For example, in the following question, the teacher drew a picture of a hand pushing a book.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

The following questions are all about this scenario.

whereas

One of the questions is, please explain why the book moves.

After my brother went to a public school, I sent my sister to a private school, and the gap after half a year made me indescribable...

The daughter's answer was, "The book moves because there are hands pushing the book."

At first, I thought my daughter's answer was quite good, but I never expected that it was this answer that she was deducted as much as 5 points.

To be honest, I was still a little unconvinced at that moment, so I asked the teacher for a theory.

As a result, the teacher gave me her answer, and I realized how difficult it was to get this question right.

Because the teacher said

The child must be rigorous and "explain more", that is, explain more comprehensively.

Students have to say that because in the picture, only the hand pushes the book from right to left, but there is no force exerted on the book from left to right, so the force is unbalanced, so the book moves.

You see, this explanation is more rigorous than my daughter's previous explanation.

It has two aspects:

The first is to state the direction of the force that causes the book to move.

The second is to explain that the object is moving because of the uneven force exerted on it.

If the child answers the above two points, he can get a full score, otherwise he will be deducted a lot of points like his daughter.

It is precisely because of this training that children's cognition of things will be more scientific and rigorous, and this rigor is the trait that teachers hope children to gain the most.

After reading the children's test papers, I was quite inspired.

I thought that even if I answered, I would not get a full score for my answer, and it would not be as comprehensive and rigorous as the teacher required.

Although my sister's results in this exam were not satisfactory, I felt that I had gained a lot.

The most rewarding thing for me is to be a child

The Son goes to explain the world

of this ability of the world

Everything in this world has its own laws behind it, and children can describe and explain it from a scientific point of view, which is a good exercise for children themselves.

Moreover, in the process of describing all things, learn to describe the principles behind them from different angles and different aspects, which also requires children to have good thinking skills.

And these are some of the things that we overlook, but that need to be strengthened for our children.

"You're great", I smiled and comforted my daughter.

She was still a little depressed, but when she heard me praise her, the little girl suddenly raised her head in surprise.

"It's great that you've learned so many complex physics concepts," I said, "and you can explain the phenomena in life with physics, which is not easy!"

The child's mood changed so fast, and she was still muttering unhappy, but in the next second, a smile appeared on her face.

"However, Dad has a little advice for you", I changed my words, "In the future, I need to be more rigorous in describing the problem!"

"Hmm", my sister happily agreed to me, and then she proudly said to her brother, "I'm great!"

The elder brother shrugged helplessly and smiled bitterly: "These post-10s are really confident......"
