How to Mathematical Mental Representation Ability? What are mental representations?

My teacher taught me to memorize concepts, no matter how complex the problem is, in front of thousands of concepts, it will fall apart, you know, the problem is the concept of creation, at least listen to her words, I have not been in the top 3 ps of the grade in mathematics, 183 students in the grade, Shanghai.

You must be interested in learning mathematics, and don't set yourself how many problems you do, so you will lose interest and you won't be able to learn well.

Personally, I think we should pay attention to textbook knowledge (after all, the college entrance examination is still basic knowledge), and a certain amount of exercises should be done accordingly.

Remember that math is a matter of calculation, not of reading.

It's a good choice to read the textbook.

I'm afraid it's hard to improve substantially.

Ask your math teacher.

Hello, the term mental representation I think it would be better if you could provide the context, and I would explain it to you in conjunction with the context.

This can be compared with you, students who study well and students who study hard for me, when I go to school by myself, the top student in our class, never looks at when he studies, slips around, studies well, and can take the first test, some things have some problems, some homework is not a problem at all in the eyes of others, and there will be students who study seriously, they study very well, but through their own efforts, they get up early and are greedy for dark snow, so they get good results in the exam.

I myself think that this is the difference between the heart of a genius and an ordinary person.

I believe that there is a genius, but the genius spends more time studying behind the scenes. If there is a genius, then I also firmly believe that hard work can surpass genius, which may be due to genetics or acquired education. Genetics and environment interact to create genius.

"Hurt Zhongyong" is the result of the acquired environment, and the genius has become an ordinary person, and besides, if he is a mentally handicapped person, no matter how good your education is, he can't make him a genius. Geniuses have better memory, thinking skills, and the like than the average person. As for emotional intelligence, it is not necessary that the emotional intelligence of geniuses is higher than that of ordinary people, emotional intelligence includes many aspects, interpersonal communication, self-care ability, etc., some people have a high IQ but poor self-care ability.

Representation is not simply a subjective reaction to objective things, maybe the encyclopedia has its own context, or the editor's own understanding is fundamentally wrong.

The so-called mental representation is only the form of knowledge in the mind, and this definition cleverly avoids the confusion between subjective and objective. For example, if you represent the concept of God, you will have in your mind the image of God (what you imagine), the concept, and so on.

But it is understandable that he compiles the encyclopedia in this way, because all knowledge can be regarded as objective relative to the self. Take the concept of God as an example, although God is a subjective concept, but it is objective to you, you listen to others, read books, and are influenced by social culture, you will have your own image of God about God, this image does not come from anywhere, it is your own subjective derivation, isn't that exactly "a subjective reflection of objective things", that is to say, you can understand the distinction between subjective and objective with a slight change. The so-called objectivity does not mean objective existence.

It's also worth mentioning that you don't agree with the concept of schema. Schema is not a representation, and it should be accurate to use portrait or image representation in your sentence.

A schema is actually a kind of cognitive structure of the world or the outside world, and a series of ways to arrange a series of knowledge that can be imagined. Something that is implicit, usually imperceptible, but a schema affects every aspect of your life. No.

Bruner (a psychologist), he summed up three forms of mental representation: symbolic representation (the concept of God), portrait representation (imaginary image of God), and action representation (doing radio exercises or something).

I looked up the "representation", and the first thing he said was the definition I was talking about... Which one did you check?

Because all of our "psychology" is a subjective reaction to the existing world, that is, to "objective things."

When you talk about God, it is subjectively conceived in the sense, but in real life she is an objective concept, and the objectivity here refers to the objective existence of the word God.

Subjectivity and objectivity come from different perspectives.

There is no absolute subjectivity or objectivity for different things.

is a reflection of objective things This sentence is preceded by a subject.

The subject is subjective to oneself, and to other things, other things are objective, so it is the reaction of objective things.

Early childhood mathematics learning is mainly divided into six modules:

1. Collection: Teach children to learn to classify, help children perceive the meaning of collections, and gradually form the concept of sets about specific things, which is the premise of counting, the basis for forming the concept of numbers, and preparing children for their mathematical ability.

2. Counting: Children always start with verbal counting and then count in combination with physical objects. From meaningless numbers to grasping the actual meaning of numbers, recognizing numbers, understanding numbers, using numbers, and finally forming the concept of numbers.

3. Quantity: Through the learning of sets and numbers, children perceive from imprecise sets to exact quantities, which is the transition from concrete to visualized quantities, laying the foundation for the concept of addition and subtraction.

4. Shape: In the early stage of children's mathematical enlightenment, in addition to addition and subtraction, there is also the learning of geometric figures. Geometry occupies a very important proportion in mathematics and also has a very important impact on the development of children's spatial three-dimensional thinking.

5. Time: Children's understanding of the clock can help them form the concept of time, help them develop good and regular living habits, and help cultivate children's punctuality concept, which is of great significance to children's growth. Communicate.

6. Emptiness: Spatial thinking refers to the ability to identify the shape, position, and spatial relationship of objects, and to form new visual relationships through imagination and visualization. Spatial thinking can effectively help children learn geometry and other types of problems, and play a role in the development of children's brains.

Children with spatial thinking can jump out of the limits of points, lines, and planes, and have multiple angles"Three-dimensional thinking", which will have a profound impact on its future social development.

Use language that children can understand, interesting topics and games, from concrete to abstract, and really cultivate children's mathematical thinking! Let every child love math!

If I'm not mistaken, classmates, do your own homework, so that you don't listen to the lecture.

Verb, representation is our perception of external things, the same thing, our mental representation is different, it is related to the experience of each of us.
