An analysis of the reasons why xiaoshengchu often loses points in mathematics exams.
1. Weak basic knowledge

This is a common problem for students who have never scored high in the exam. If you get 95 on the question of 100, this has nothing to do with you, but if you only get 59, you should take a good look at this.

I believe that teachers who only like to talk about key and difficult points and let students read textbooks to understand basic knowledge points are not just legendary teachers. Of course, it's not that the teacher is bad. After all, there are so many people in a class that as long as most of them can adapt to his teaching methods, it is not a failure.

But it does not rule out that some students may not even know the basic definition.

Not clear about the definition of equation (and the formula of equal sign), so he thinks that 1=2 is not an equation, but 3. 14 is an equation.

I don't know the definition of the equation (an unknown equation), so he thinks that X+ 1=X- 1 is not an equation because it has no solution.

Children with this kind of problem raise their hands silently. It is not too late to start from scratch.

2. Poor basic computing ability

This is probably a problem left over from history. If a child is not good at computing from an early age, it is unlikely that he will suddenly become a human computer after middle school.

Other children are used to using calculators. In the long run, it is strange that their computing power is not weak.

(- 10)5? (-2/5), how many people got -50 on this question? Alas, impulse is the devil, who let you combine the back so impulsively? Talking too much is all tears.

3. Poor practical application ability

When it comes to equations and inequalities, math problems tend to be applied problems, which are mostly combined with life. At this time, some students don't know how to apply mathematics to life, which is simply fatal. For example:

Six teachers and 234 students are going out for activities, and they are going to rent 45 carts or 30 carts. If they rent 1 cart and 2 carts, the rental fee is 1000 yuan. If you rent two big cars 1 a small car * * *, the rental fee is 1 100 yuan.

How much is the rent per car? If each car must have at least one teacher, and the car rental fee does not exceed 2300 yuan, what is the most economical car rental scheme?

There must be a child's reaction to this question: wow, I have seen this question, that is, what is on it, what do I see? Oh, dear, I forgot.

4. Poor logical reasoning ability

This is probably the point where many people lose points. Many students always take this factor into account when doing problems, and forget the other one. Especially the calculation of numerical range.

5. Lack of serious exams and standardized problem-solving habits.

This is probably a personal habit. Many people are impatient and start to do problems before they finish reading them. For example, the first few questions in multiple-choice questions are always relatively simple. You will know the answer at a glance, and then some children will read half a sentence. Alas, this question has been done before, and the answer is A, and then 5 points will be gone.

It's not such a fast way to make you do the problem quickly. How do you know that the problem is still the same as what you have done?

careless

Often after the exam results come out, people say, hey, why is it so much less than my estimated score? As a result, if you take a closer look, many of them are careless, right?

7. A skilled artist is timid

There are always some students in the exam When they make choices and fill in the blanks, they will repeatedly check the slightly more difficult questions and always worry about their computing ability. In this way, they will delay the time to do the problems later. Why? Because you are not confident and timid.

8. Low speed

Every exam, students say that I can do this problem clearly, but I don't have enough time. But the exam time is the same. Why do others have enough time and you don't have enough time?

The reason is that the problems that should be completed quickly are done too slowly. Why do you do it slowly? Usually practice is not enough, and the proficiency of related issues is not enough. Why are you not proficient in these relatively simple questions? This is a common problem of some students who are good at math. They spend all their time solving difficult problems, but their grasp of basic problems is a bit neglected.

9. the last two steps of the final finale are simply impossible to start.

Generally speaking, the latter two questions are sub-topics. Maybe you can work harder at ordinary times, be careful in the exam and don't fall behind. The last question is not that you can work hard if you want to. The test is a comprehensive application of mathematical thinking and mathematics, so you can't go wrong with that score.

10. Get twice the result with half the effort before the exam

Many students are too busy to stop when it comes to exam time. They are busy reciting and doing problems. However, the results of the exam didn't surprise you.

Why? Doing questions before the exam has no substantive effect except giving yourself some self-comfort. What we have to do is to review the previous wrong questions and see what kind of questions we can't yet, but the point is not.

However, most of the points lost are due to one or more of these reasons. Find your own reasons, suit the remedy to the case, practice more, read more and summarize more, and mathematics is no longer an obstacle.
