Why do you want to brush the questions?

I have been brushing junior high school questions these days, because I haven't touched junior high school questions for a long time, and many of them don't remember. I want to find them and solve them. By the way, I am familiar with the questions in the current senior high school entrance examination.

After brushing the questions for a few days, I did find some problems. For example, some concepts are forgotten, some questions don't know where to start, some can do it right, but they don't know how to write the steps, and some think they can do it, which means it will take a long time to do it. Of course, there are still some questions that are a little difficult to understand even after reading the answers.

There are different opinions about brushing questions, but teachers will ask to brush questions before the exam, big or small. The importance of brushing questions is self-evident.

Then I will talk about my feelings now based on my experience in brushing questions these days and my previous experience.

First of all, talk about the benefits of brushing questions:

● Broaden your horizons and look at new problems.

● Skilled skills make the knowledge and skills you have learned perfect.

● Find the same type of questions and conduct special training.

● Find out and solve problems.

Generally speaking, these four benefits, if there are other benefits, look forward to correcting them.

Why is it wrong?

My original intention of brushing the questions this time is to review my previous knowledge and look at the current questions. In the first few sets of papers, basically every set can encounter concepts or problems that can't be met. There will be fewer unfamiliar concepts and fewer unfamiliar questions. However, you can always see problems that you can't do. After all, it is an exam question for the senior high school entrance examination, which is understandable. But I must analyze the reasons, otherwise I will never solve the problem. Brushing questions is not a problem that cannot be brushed. Just solve this problem and it's over. We must find the root cause, which is why we can't remember it at that time. Think again about solving problems and see where your blind spots were at that time and how to avoid them.

After such analysis, I will find that there are mainly the following reasons (concept forgetting has been ruled out):

● The theorem is unfamiliar. For example, what theorems are there to prove that triangles are similar? What theorems prove that a parallelogram is a diamond?

● Some problem-solving skills are not skilled, such as the relationship between two roots when solving binary linear equations, the representation of vertex coordinates of quadratic functions, and so on.

I have seen similar problems, but they still interrupt my thinking. For example, finding two line segments equal is often proved by congruence. Some have to bypass some circles to prove congruence and can't see it directly; Some of them are not proved by seeking perfection at all, but by seeking similarity, so as to find proportional line segments, and by substituting other line segments, so as to find equality.

● Some questions are too difficult, just give up.

How to solve the above problems?

? In the first case, we must sort out these theorems again, and distinguish the theorem of proving triangle congruence from the theorem of proving triangle similarity. Then watch all the exercises after class carefully. Some inferences or conclusions that are neither inferences nor theorems can be the breakthrough points to solve problems in the future.

The knowledge points thus sorted out will be more reliable in memory. In the future, similar problems can be solved by exclusion. This turns a solved problem into a multiple-choice question.

? In the second case, it proves that this knowledge point is not skillfully used, and it is necessary to find the same type of questions and do more exercises. It's not just about sorting out knowledge points. Focus on a lot of deliberate practice. It is mainly through practice that some conceptual knowledge is turned into conditioned reflex. Seeing this kind of problem, you can think of those formulas without much thought. Just like in primary school, we will recite some interchanges between fractions and decimals and percentages. It's not that we can't figure it out, but that writing it down can save time and open the way to solve problems (the common factors of some simple operations will appear in different forms of fractions and decimals).

? For the third case, it is not that the knowledge points in the book are unfamiliar, but that such questions are unfamiliar, or the ideas for solving problems are not broad enough. Be sure to find the same type of problems, practice a few more, and then summarize the law of solving problems. For example, there are several methods to find the sum of equal line segments and several methods to find the shortest distance. After summing up, if you encounter the same type of questions in the future, you can turn the problem into a question of which method to choose.

? In the fourth case, do what you can according to your own ability. I won't consider solving the last situation until other problems are basically solved. Just look at the answer first and understand the question first.

How to brush?

Although brushing the questions has many advantages, don't brush the questions blindly, which will not only waste a lot of time, but also hurt confidence. It is for this reason that many senior three students have studied for a year and even failed in the college entrance examination.

So how should we brush the questions correctly?

For students with poor foundation (below 75, full mark 100), the best way is to brush the questions according to the chapter. Of course, you can skip the chapters you are familiar with. What is familiarity? That is to say, if you do the unit test, you can get more than 85 points (this depends on the different requirements of different students and the situation).

Constantly consolidate knowledge points by brushing questions and skillfully use knowledge points at the same time. It is best to brush the questions with the teacher's company, so that the teacher can help you in time if you can't answer the questions, so as not to dampen your confidence. You can choose to give up if you still can't understand the answer after reading it, or if it is difficult to understand.

Students with a good foundation (75 -90 points) can brush the questions according to their own feelings. If they don't think it's very good, they can brush the title of that chapter.

How to "feel"? If you are not sure which chapter is worse, you can make a comprehensive volume. When you see a certain type of question, you will feel a little scared, or you will worry about what type of question you will encounter in the exam. Then these questions are the ones you don't feel good about. Pick out these chapters separately, and then do the same kind of questions well until you are no longer afraid.

When the difficulties I felt were finished, I began to brush the comprehensive paper. If you find problems in the comprehensive paper, if it is still the basic knowledge in the textbook, then go back to the textbook and brush the chapter knowledge points. If it is a comprehensive application of cross-chapter knowledge, then find the same type of questions instead of brushing the whole paper, such as just brushing the answers or filling in the blanks. Summarize the rules until you understand that there are several solutions to this kind of problem and which solution to use under what circumstances. When you encounter the same type of questions in the future, you should study them together. At this time, if you encounter problems, you must ask the teacher and ask the teacher to help you summarize. It's easy to get to the bottom of your own research.

Students with good grades in the end will brush the comprehensive questions directly. On the one hand, broaden your horizons and see more problems; On the other hand, find out your relatively weak knowledge points and further strengthen the consolidation. Another aspect is to hone your patience and reduce unnecessary careless mistakes. Every careless mistake at this time may be a subconscious misunderstanding, so don't let it go easily. You must seriously think about why you made a mistake at that time and how to avoid jumping into the pit next time.

How to use the wrong book?

When it comes to brushing questions, you can't leave the wrong question book, but I love and hate it. "Hate" is because copying questions is too troublesome. "Love" is because it really works. Every time you encounter a problem, you can basically find a shadow in the wrong book.

Let's talk about the usage of the wrong book first:

1, about the knowledge of objective memory, copy it if you are wrong.

If you are not proficient in chapter knowledge, don't copy it in a hurry. Go back and practice the corresponding chapters first. We'll talk about this when it's over. If you think this question is still worth recording, then record it again.

3. Write down the skill-based problems and comprehensive application problems that you can't do.

If you remember the wrong question, you can't copy it without copying it. Cut directly. Because my handwriting is not good-looking, I would rather cut it. Otherwise, I think the possibility of seeing it will be greatly reduced.

5, don't be stingy with the wrong book, use a medium book and turn pages left and right. Remember only 1-2 questions on a page, and don't remember too many questions, except minor ones. But it is not recommended to remember too much. Don't write the answer directly. The answer is written on the back cover. You can't see it directly, but it's easy to find.

The biggest precautions for brushing questions! ! !

The biggest problem in brushing questions is to know your mistakes and not change them! It's not like it won't be modified. It's that you revised it, didn't analyze the cause of the error, didn't contact the same type of questions you did before, and continued to make mistakes next time you saw it.

I remember every time I finished my math exam in high school, I made mistakes. I will feel suddenly enlightened after the teacher finishes speaking. Why is such a simple question wrong again? Or why you can't remember it during the exam. Whenever this time, I scratch my head and look regretful. But next time I meet, I will continue to make mistakes. Now that I think about it, it's because I didn't calm down and analyze the reasons. Then compare the same type of questions to see what are the similarities and differences and where are the breakthrough points. After such an analysis, I believe that at least I am not wrong or ignorant.

Of course, analysis takes time, and you can't expect the teacher to finish it right away. Many times, you need to spend more time analyzing. A topic can be as short as tens of minutes and as long as half a day or even a day.

That's all I feel about brushing the questions. I hope it helps you.
