What should mathematics major learn after entering private placement?

At present, teachers often criticize students, who have no memory, forget what they have just learned in a short time, and do badly in exams. We can think about it: what is left in our minds about what we have learned in mathematics?

Forgetting is normal, the key is what is left-that is what will benefit us for life!

A little idealistic. I thought so a year ago, but now I have to follow the trend.

When the sextant teacher mentioned this question, my heart was really cold. This semester, I forgot all the contents of last semester, and some even forgot some key knowledge mentioned in the last chapter. Forgetting, we must be sure. The key is how to teach students to overcome forgetting.

Now it's the opposite!

What you want is integral!

I also want to ask: What's the use of studying mathematics for so long?

Is there a problem? !

Have you really forgotten everything you learned in math class? At least remember the addition, subtraction, multiplication, division and decimals taught in primary schools (I guess I will never forget them).

Ok, let's look at it now: Why do you remember what you lived in primary school, but not what you learned in middle school?

Different opinions will get different results!

If you think it's because you have more and more knowledge, then you can fully understand why there are people who use sea tactics!

Welcome to discuss!

Because I personally think that the knowledge of mathematics in primary and secondary schools is very simple and not easy to forget, so I can't understand the thoughts of those who are not good at mathematics!

If a person can't remember the conditions of the topic after reading it, it is really difficult to teach him to think! )

I remember all the mathematical formulas and so on!

I almost forgot English! No, forget it if you don't understand!

There is an experiment like this:

Students in a key class (for example, the score of chemistry can reach 890%) are asked to do the same test paper after three years, and few people pass. None of the questions answered are accumulated memories.

I can't remember the expert's comments clearly, and it's not good to add or subtract them casually. Let me talk about my own views. I think what mathematics should learn is the ability to analyze and solve problems, and it is not advisable to memorize a certain kind of problems. But now the general direction is so helpless.

When I was in the sixth grade, I didn't know anything about application problems. At that time, my dad gave me counseling every night. He often said, "I went to junior high school, and I will look at such problems after high school." At that time, I took this as a comfort, but after I entered junior high school (after the second grade), I found it was like this. Now think about it, because of the improvement of thinking ability. However, the knowledge of primary schools can't enter colleges and universities, if the college entrance examination.

Obviously a student!

Let senior liberal arts graduates come back to do middle school mathematics (not necessarily as difficult as the college entrance examination), 99% can't do it!

Science (non-mathematics major) graduates may have no problem doing algebra, but they will be too big to do geometry, and the formula of trigonometric function will probably be forgotten!

Mr. Ye Er, don't you think it's useless to study math?

In other words, is the mathematics knowledge we learned in middle school useless?

It seems that this problem is going to be discussed!

What is the purpose of learning that knowledge!

Is to learn his thoughts and his ability to solve problems!

I think the actual effect of local knowledge points is not great!

For example, triangle knowledge, how much will a person use in his life!

I think mathematics is the least practical science. After four years in college, what you have learned is completely useless in middle school. What are you studying for these four years? ! ! !

A person's world outlook and methodology are gradually formed in the process of learning.

I only know that I have learned a lot in college for four years, and now I am asked to do college questions. If I hadn't censored them, I might have survived.

But one thing is certain: when I was studying, I always asked my teacher for any questions. I always feel that the teacher can grasp the key points quickly and feel that the teacher is really sorry. But after graduating from college, when I look at high school topics again, I always think, why couldn't I do such a simple topic in the first place? What do you think is the reason?

I don't need to tell you why!

Typical pragmatism,

Ye Er, the teacher upstairs, said that "triangle knowledge is seldom used". This view should be viewed comprehensively. For ordinary people, knowledge of trigonometric functions is really useless. What they know is addition, subtraction, multiplication and division, and they can be used in real life. The knowledge of trigonometric function is widely used in physics, surveying, applied mathematics and other scientific and technological fields.

Suddenly, I had an idea that the knowledge of primary school taught by the teacher upstairs was very simple, and I suddenly found that the knowledge of primary school has applications in real life. So you didn't let the students know about primary school, and now he knows. I fell into a strange circle ~ ~ ~ ~ ~ ~ ~ ~

After reading these posts, I remembered some jokes about "Mathematicians are aliens" that Edil posted on the towel of the old forum!

Trigonometric function knowledge has a wide range of applications in the field of science and technology, such as physics, surveying, applied mathematics and so on.

It is very useful, but how many people use it!

Why do many people learn things that few people use?

I think we should pay attention to the difference between "knowledge point" and "knowledge"

When learning mathematics, the thinking of solving problems and the thinking method of dealing with problems are very important, but local knowledge points! Is it useful?

Some knowledge points really seem "useless".

Trigonometric function can also be considered as other foundations, because after that, there is no concept of trigonometric function, and many problems cannot be explained. (It also involves other disciplines! )

The most "useless" should be geometry, not as much as trigonometric functions!

However, the proof of geometry has exercised our rigorous way of thinking, which may not be prominent and easy to be ignored by everyone.

What is the purpose of learning mathematics? I once asked students when I was teaching, and some students directly answered "for the college entrance examination". I have to ask myself now. ......

I agree!
