How to check and fill in the gaps in the junior high school math review class

Lingyun: I am very happy to receive the letter and learn that you have made great progress. According to the request of your letter, talk about how you can check and fill in the gaps in the basic knowledge in the general review of junior high school chemistry.

The basic knowledge of chemistry in junior high school includes basic concepts, knowledge of elemental compounds, chemical calculations, and chemical experiments. These basic knowledge are not only the content that must be mastered in learning chemistry now, but also the compulsory content of the high school entrance examination, and the foundation for learning chemistry in the future. When reviewing these basic knowledge, the emphasis is on consolidating and improving, so that the learned knowledge is organized and systematized, and a complete knowledge structure is formed in the brain.

This not only consolidates knowledge, but also facilitates the application and improvement of knowledge. In order to achieve the above goals, it is not possible to rely only on the teacher's summary and review in class, but also to recall and summarize the knowledge by yourself, that is, to conduct self-examination. Self-examination is to check what you have learned well and what you have learned poorly in the study of basic knowledge through your own review of the learning content without reading the textbook, so as to find out the weak links in the learning and re-study and re-consolidate in the review.

In the memory, all the basic knowledge that you can recall quickly is the knowledge that you usually learn well or relatively well, and you can do a general review of these knowledge. All the basic knowledge that cannot be recalled, or can only be recalled after a long period of thinking, is the knowledge that has been forgotten or learned relatively poorly, and these knowledge are the focus of one's own review.

1. There should be a direction for review: sort out your own learning and mastery, based on textbooks, combined with your own notes, test papers, weak links, existing problems, etc., allocate time reasonably, and target and specific to overcome and implement little by little.

2. You can learn to master the ability of speed reading and memorization, and improve the efficiency of learning and review. Speed reading and memorization is an efficient learning and review method, and its training principle is to activate the potential of "brain and eye" and cultivate the formation of eye-brain direct reflection reading and learning mode. For the practice of speed reading memory, see the "Elite Special Whole Brain Speed Reading Memory Training Software", with software practice, more than an hour a day, a month's time, you can double the reading speed, memory, attention, thinking, comprehension, etc. will also be improved accordingly, and finally improve the efficiency of learning and review, and achieve good results.

If your reading and learning efficiency is low, you can practice it well.

3. Learn to integrate knowledge points. Classify the information you need to learn and the knowledge you need to master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review, and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system.

This promotes understanding and strengthens memory.

4. When doing problems, you should learn to reflect, classify, and sort out the corresponding solution ideas. When you encounter the wrong questions (carelessly do it wrong, you can't do it), it is best to collect these wrong questions, and each subject has an independent set of mistakes (the set of mistakes should be classified), and when we review before the exam, they are the key review objects to ensure that there are no more mistakes and points on the same questions.

Mathematics research and teaching must grasp that new knowledge is generated from the first generation, and teaching in accordance with the order in which knowledge is generated is the essential requirement of mathematics.

The order in which the knowledge in this section is generated is:

Area Problem Integer Multiplication Factorization.

Explanation: 1. "Integer multiplication" is derived from the problem of area ("product of length and width") with a rectangle as the basic figure, so the integer multiplication must be carried out from the background of the area problem when teaching;

2. Factorization is the inverse operation of integer multiplication, to study factorization, we must seek from the relationship of integer multiplication, therefore, the arrangement of learning factorization after integer multiplication is in line with the requirements of the order of knowledge generation, so that the arrangement grasps the intrinsic connection of mathematical knowledge, and it is convenient to grasp the essence of mathematics when teaching.

Teaching essentials: 1. The mathematical model of "integer multiplication" must be established from the area problem, so that students can experience the awareness of mathematical knowledge generated and applied in practice;

2. The generation of the principle of factorization must be observed through the operation formula of integer multiplication.

I don't have a book, to sum up, junior high school mathematics is very simple, as long as you put your mind to it, you will definitely be able to learn well, pay more attention to the summary, follow the teacher, and do more problems.

In my opinion, in short, it is to do the problem, the experience comes.

Catch a formula or something, if you can't remember it, you can search for relevant questions to do, do it a few times to understand, ask for a few aspects to contact, you can ask the teacher, the teacher is the last retreat

Read the textbooks, set up exercises, copy the wrong questions, do the wrong questions, re-study the wrong questions, and focus on special exercises.

1. Copy the wrong questions and make the wrong questions.

Copy out the wrong questions, and do it again or more times after copying, so that the mastery of knowledge is useful. However, in order to complete the homework quickly, many children will choose to copy the answers directly, so that the coping homework is actually ineffective at all.

Therefore, parents can ask their children to copy out the questions they did wrong after the midterm exam, and then let the children do it several times.

2. Re-study the wrong questions and focus on special exercises.

After these weak modules are detected through the test, these weak modules can be supplemented in further study after completing the wrong questions.

If the math score is not satisfactory, at this time, after completing the study of the wrong questions, you can talk about the math definition that you have learned in the first half and take it out again to do it and memorize it.

3. Read textbooks

Including learning the various knowledge points on the textbook, carefully figuring out the process of solving each example problem, summarizing the method of using knowledge points to solve problems, and at the same time, you can refer to the detailed analysis of these knowledge points and example problems in the teaching book, which can effectively improve the efficiency of preview, and better understand and master the knowledge points.

4. Supporting exercises

After previewing the content of a chapter, it is best to do some synchronous exercises, so that you can deepen your understanding of the knowledge points and learn how to use the knowledge points to solve the problems. It is best to choose the type of question with basic difficulty for synchronous practice, the amount is not too much, but the question must be passed, and it must not be ambiguous, only in this way can the purpose of digesting and absorbing the knowledge points be achieved.

The basis of checking and filling in the gaps is to know that you are missing and missing in **. You can use textbooks as the basis, combined with your own notes, papers, etc., to sort out your knowledge and your own mastery. Find out what you haven't memorized, what you haven't understood, what you have ignored before, what questions you did wrong, what are the reasons for doing wrong, and so on.

Whether it is concepts, principles, formulas, or specific knowledge points, they should be marked and sorted out.

If you know your own problems, you can overcome them in a targeted manner. If you don't remember, you should take time to memorize and memorize, and if you don't understand, you should quickly find teachers and classmates to understand. Many students are afraid to ask questions to their teachers for fear of being laughed at by them.

Teachers are dedicated to teaching and solving doubts, which is their duty, so there is no need to worry. If you don't understand something, you should ask the teacher for advice in time and solve it in time, so that you can lay a good foundation and learn steadily in the future.

For some important knowledge sorted out, memorize or learn it in a planned way. There are many ways to memorize and memorize, such as trying to recall the method, trying to recall it after learning, and then looking back to confirm and consolidate the places that you can't recall. As for some methods and training to improve memory, most of them use the ability of association and thinking, such as in the "Elite Speed Reading and Memory Training Software".

"Coding and positioning memory" is encoded to facilitate memory through "homophony, image transformation, and meaning transformation", and then combined with "human body, home", etc., to locate memory; "Mind map memory" is a structured memory that gives full play to the power of thinking and sorts out knowledge. "If you have a poor memory and have time," you can also learn.

It is rare to learn or review knowledge once and then memorize it completely, so learn to repeat itThe specific method is "interval review", that is, there is a time interval to review. According to the forgetting curve, it is after learning and remembering temporarily: after 20 minutes, after 1 hour, after 8 hours, after 1 day, after 2 days, after a week, and after a month, it will be reviewed again.

The exact interval can be set according to how long you want to memorize, which is the time of the exam. If you are going to take the exam in a week, you should revise it again every one to two days after you finish it today. If you are going to take an exam in a month, then after reviewing today, you should review it every other week; If you don't take the exam until three months later, then you can review it again in half a month after you finish reviewing today. If you don't think the number of times is enough, then increase it a few more times at time intervals.

1.Check the gaps and fill in the gaps, check the basics, and make up the knowledge points.

If you want to find out the loopholes in your knowledge, students can clearly see the loopholes in their knowledge points and questions through the wrong questions in the exam, and how should we make up for the loopholes after finding the loopholes?

2.The correct way is to return to the textbook, students should return to the textbook, start from the textbook, take the textbook as the main topic, check the gaps, and fill in the gaps.

Don't ignore the loopholes, weaknesses and omissions in knowledge, there may not be major problems for the time being, but over time, it will cause blind spots and blind spots in knowledge. When faced with a comprehensive problem, it will be found that the loss of one point will lead to the incompleteness of the entire knowledge system, which will seriously affect the improvement of the overall performance. If you don't check and fill in the gaps in time, when learning new knowledge, you will inevitably encounter bottlenecks and don't know the crux of the problem.

Can provide you with methods on revision and study:

1. Promote memory, so that the results of learning are firmly stored in the brain so that they can be accessed at any time. Some students always complain that their memory is too bad, and they can't remember what they have learned when they should use it, and they lose confidence in learning. Some students think that they should forget what they have learned anyway, and it is useless to memorize it early, and hope for a surprise attack before the exam.

However, because there are too many things to memorize before the exam, I can't remember them, so I feel very annoyed.

2. Check and fill in the gaps. There are many factors that affect learning, and it can be difficult to ensure that all factors are in the best condition in a long learning process. Therefore, it is inevitable that there will be loopholes and deficiencies in the complete learning content.

Through review, check it out by yourself and make up for it in time. All students who are in a hurry to review. The loopholes and deficiencies in learning are filled in time, so their knowledge is always relatively complete.

3. The most important point is that you can improve your memory and comprehension to make you learn more with half the effort, which is the most critical point to improve your academic performance. I have used "Nikola Tesla Training" before, after learning, I have mastered a variety of efficient brain skills, easy self-study of various subjects, and finally admitted to the university, I hope my sharing can help you, good luck!
