How to eliminate carelessness in mathematics?

Carelessness is a common problem of most students, which shows that even simple topics can make mistakes in homework. When writing, you either lose strokes, write wrong symbols, or read wrong, resulting in many unnecessary mistakes. The reason is acute, overconfident and flustered, which leads to students' emotional instability, inattention and disorder of hands and brains. Fourth, it is related to the lack of solid knowledge. 1+ 1 equals several. It is not wrong for a student to answer casually, because she has formed an automatic response. Therefore, if you master the basic knowledge and can deal with it automatically, your carelessness will be greatly reduced. Fifth, it is related to study habits. Usually doing homework is very careless, carelessness has become a habit, and you can't help but make old mistakes when you take exams. Therefore, put an end to carelessness at ordinary times, so as not to lose points in the exam because of carelessness. How to help students overcome carelessness is analyzed from the following aspects.

Various manifestations of carelessness

The performance of carelessness is as follows: some students do more than 0 questions; Or write less units; Or the decimal point is in the wrong position; Or the top line 23, it will be 32 after changing the line; Or if a word is written wrong, students are prone to make mistakes. They regard "3" as "8" and "+"as "-". For example, a classmate appears "0×6=0, 0÷6 =0, 0+6=0, 0+6=0." When you pointed out his mistake, his explanation was: 0 is meaningless, so the result of addition, subtraction, multiplication and division of any number and 0 is zero. The reason for the mistake is that the child did not understand the meaning of the four operations of addition, subtraction, multiplication and division. For another example, when a child calculates the circumference of a semi-circle, he only calculates the length of the arc and does not add the length of the chord. In fact, it's not that he neglected, but that he didn't understand the concept of perimeter and didn't know that perimeter should be a closed curve. When it comes to the exam, you won't do well in the exam, and you will make mistakes in the simple questions you usually do, or even miss the whole paper. The reason is that he cares too much about the exam and wants to do well. ..... In short, it is not an error caused by failure;

Second, the correction method

1, pay attention to it ideologically.

It is easy for an idea to go from ignorance to knowledge, but a "careless" phenomenon can often happen repeatedly. From this comparison, we can see which one is more harmful. Lenin once said, "Ignorance is closer to truth than prejudice." We can also use this sentence without exaggeration: "Ignorance is easier to get the truth than carelessness." Not afraid of "ignorance", because what you can't learn can be learned, and what you don't understand can be understood. "Carelessness" is terrible, because students think that "carelessness" is not "ignorance", so they are careless again and again and make mistakes painfully, thus wasting a lot of time and losing many possible opportunities.

Everyone has shortcomings, everything has shortcomings, and the world is not perfect. Because there are shortcomings, the world will progress and people will progress. Sometimes, people's shortcomings are defects at some time, and sometimes they may be advantages, so we often say that there is no good or bad personality. For example, a person loves to lose his temper, which should be regarded as a shortcoming. Under normal circumstances, we can tolerate or even forgive this shortcoming, but it is wrong for him to hit people when he loses his temper. Such mistakes should be investigated and corrected.

You can easily find the difference between "shortcomings" and "mistakes", but because they are often very similar, we tend to confuse them and often regard "mistakes" as "shortcomings". There is a simple reason. It is precisely because we don't know enough about the harm of carelessness and its attributes in our minds that we ignore, tolerate and even condone it.

If we want to solve the problem of "carelessness", we can't solve it well if we don't have enough, correct and sober understanding in thought. It will appear at any time like a ghost, eroding what we have achieved and hindering what we may achieve.

If you want to get rid of carelessness, you should start with your usual work habits, because only by developing careful habits in your usual practice can you avoid carelessness in exams. Don't browse when reading the topic, read it silently and read it several times, so that you can find some simple mistakes in time.

3. The calculation error in the math exam can't be counted as carelessness, which is mainly related to your calculation ability and habit. Computing ability can only be improved through repeated practice. The habit of calculation depends on your usual accomplishment. When taking the exam, be sure to use draft paper and mark the question number. If you do your homework according to the format, it is easy to find mistakes when checking.

4. Examining questions can also be exercised. I am used to reading the questions twice, so I won't make mistakes in the exam. Finally, the teacher told you to deal with the exam easily and have the courage to face setbacks. One or two exams can't tell a person's true level. Careful examination of the questions will help you get good grades every time!

In order to overcome carelessness, we should pay attention to what we have to do. For those unimportant things, we will not take them seriously, and we will be careless. For example, when doing homework, many students think that writing typos is a trivial matter, as long as they can write, so they often write typos because of carelessness; Some students make mistakes when doing arithmetic problems because they don't pay attention. They wrote 7 as 1 and the plus sign as the minus sign. However, after we get into the careless habit, it is easy for us to write wrong words or write 7 as 1 because of our habit, which leads to failure in the exam. Therefore, carelessness should be taken seriously in order to correct it.

6. Get into the habit of checking carefully after doing things. When we finish a task, we should carefully check what we have done to see if there are any mistakes caused by carelessness, so that those mistakes caused by carelessness will be corrected. For example, after finishing homework and exams, carefully check whether there are any typos and numbers, check whether you have all the books to use in class before going to school, and check the papers and pens to use in exams before going to school. These are all very good habits.

7. Gradually develop a meticulous character. Generally speaking, boys are careless and girls are careful. Therefore, the questions that girls can do will not make mistakes because of carelessness, while the questions that boys can do will not be scored because of carelessness. This is the reason why many girls do better in school than boys. Careless boys need to develop a meticulous character.

To cultivate a meticulous character, I will introduce you to an exercise method: needle-piercing exercise. The exercise is simple. Find a needle and put a thread about 5 cm long on the nose and eye of the needle. Find another piece of cardboard and punch 20 holes in it with a thicker needle, with 5 holes in each row and 4 holes in each row. The method of practice is to hold the thread by hand and put the needles into the holes of the cardboard in turn. Each exercise 10 minute, twice a day. After a while, you will find that your carelessness has improved.

Good grades come from good attitude.

Unlike ordinary people who do small questions first and then big questions, Guo chose the order of answering questions in this college entrance examination: big questions first, then small questions. She is used to this way of answering questions, and the more she does it, the easier it becomes. She said that this will not only make big problems calmly, but also have enough time to check small problems.

She believes that taking the math test is actually taking the mentality test. Once you get flustered, many mistakes will follow. "I was very flustered when I used to do the problem. I have been worried that I can't finish the questions, so I want to finish the small questions as soon as possible, but I often lose points. "

She introduced that when answering questions, you should choose your favorite answer order. "Whenever I get a test paper, I have to browse the distribution of difficulty and simple questions first, and allocate the answer time accordingly." "If you have an overall grasp of the test paper, you can naturally deal with it calmly and effectively reduce the error rate."

To solve problems, we should strive for victory steadily.

Another examinee, Luo Hao, said with a smile that his math scores have been very good, and the biggest trick is to be serious.

"No matter what topic you do, you must calculate it yourself and write it step by step." Luo Hao said that when practicing, he always pays great attention to the writing standard, and every key step is not lost. So you won't lose points because of incomplete exam steps.

Luo Hao suggested that it is not necessary to solve problems quickly, but we should strive for victory slowly and steadily. "Every time I do a problem, I first calculate the problem on the draft paper, and then calculate it again on the test paper. If you do each question twice, the correct rate will certainly increase. "

Don't be afraid of the "four strokes" to defeat the "enemy" and welcome the triumph before the exam.

In the second half of senior three, I often hear some students say that they are bored and can't study. What's more, students fight with each other because they are in a bad mood. How to relieve these irritable and depressed emotions and give yourself a good mood, students may wish to start from the following aspects, which can play a certain role.

Avoidance transfer method When you are in a bad mood, the first and easiest method is avoidance transfer method. Avoid or avoid contact with external stimuli and environment that lead to bad emotions. In a bad emotional environment, a strong excitement center often forms in the human brain, which avoids the relevant external stimuli and can make this excitement focus give way to other stimuli to cause new excitement centers. The excitement center moved and got rid of the psychological dilemma of being in a bad mood. "If you don't listen, you just don't mind." That's what I said. This also reflects the difference between psychological injury and physical injury. If I hit you, you will feel pain immediately, but you will be annoyed, laughed at, etc. Only when you miss them will you feel their existence. As long as you don't want people to be sad, they won't bother you. People who are in a bad mood always focus on the object that causes trouble, and their feelings stay in the experience of trouble, so they should have a good mood and pay more attention to the positive side of things. Some things are wide open from another angle, and a story illustrates this point. According to legend, an old lady had two sons: the first one sold umbrellas and the second one dried salt. The old lady worries about her two sons almost every day. What are you worried about? Every sunny day, the old lady would say: on such a sunny day, umbrellas are not easy to sell! So I'm worried about my eldest son. Every cloudy day, the old lady whispered, It's raining on this cloudy day. How can the salt be dried? So I'm worried about my second son. The old lady was worried and haggard. The two sons don't know what to do. Fortunately, a wise man made a suggestion: "sunny days are good for drying salt, so you should be happy for your second son;" It's easy to sell umbrellas on cloudy days. You should be happy for your eldest son. If you change your mind like this, you won't worry! "In this way, the old lady really turned grief into joy, and she was broad-minded and healthy. In addition, when you are in pain, concentrate on doing something meaningful and happy. Can reduce troubles and stress. For example, in a major table tennis match, excellent athletes often divert attention and reduce stress by tying shoes at the critical moment when deciding a goal, so as to relax their nervous mood and win.

Psychological masturbation is also called "spiritual victory method". What if some students always want to fail the exam before the exam? Because negative mentality affects the normal performance of the exam, we might as well comfort ourselves that if we fail in the exam, others will fail in it, so as to maintain psychological balance. Even if you fail in the exam, there will be another time, "A blessing in disguise is a blessing in disguise" and "Sang Yu in the east corner". After finding the right question, the next time will be better. Faced with setbacks and failures, we can't just hold our breath and become dejected and despondent. Anger is to punish yourself with other people's mistakes. We should eliminate psychological depression and boredom, achieve a positive psychological balance, rise from confusion and be a strong man in life. Allen, world 1 10 meter hurdler? Johnson set an example for us. He accidentally fell down at the 2008 Athens Olympic Games and lost the gold medal he had prepared for more than ten years. But he smiled and said, "This is just a small setback in my life. I am still the best athlete in the world 1 10 meter hurdles. "

Humor-inspired laughter is a regulator of people's psychological emotions, and the pleasant effect of laughter can regulate people's psychological activities. Dispel all kinds of sadness and depression, eliminate loneliness and depression, correct withdrawn and introverted personality, and make people become open-minded and generous. Laughter is also a kind of spiritual disinfectant, which can help people get rid of troubles and depression. When career and life are frustrated and communication is deadlocked, humorous behavior and humorous language can often turn difficulties and embarrassment into ease and nature, thus relaxing mental tension, easing atmosphere, releasing emotions, relieving anxiety and getting rid of difficulties. For example, the great philosopher Socrates had a bad-tempered wife. One day, Socrates was talking to a guest when his wife suddenly came in and made a scene, throwing water from the washbasin on Socrates. How embarrassing is the situation? This is unbearable for a man with a little blood. Socrates smiled and said, "I knew there would be heavy rain after thunder." His wife couldn't help laughing when she heard a sentence. Let our life be more humorous, and we will have more good moods.

Self-catharsis When we get into deeper troubles and hardships, we should vent our pain in time. Psychology believes that anger, like imposing restraint, is like a time bomb, always in danger of destroying yourself or others; If grief is suppressed and not vented with tears, it will not only endanger physical and mental health, but even die. On appropriate occasions, let your anger explode by crying and shouting. It is said that there is a sandbox filled with fine sand in the office of an American president, which is used to vent his anger when necessary. You can also tell your close relatives and friends about your grievances and pains, and even tell yourself. The best way is to write in a diary and let the pain in your heart flow out along the pen. You can also vent your depression by running and other forms of exercise, and forget your troubles and worries.

Finally, keep a normal mind. In the fierce college entrance examination, people instinctively raise their expectations of academic performance, treat themselves with unrealistic expectations, and sigh, "Why do I shine?" This makes some students spend precious time in depression and resentment every day, and can't enjoy the happiness brought by study. As the saying goes, people are more popular than others, which is the reason. Psychologists point out that the higher the expectation, the greater the psychological and emotional conflict, and the higher or lower the expectation will affect the normal level. Therefore, we should keep proper expectations, put ourselves in a proper position and let happiness accompany us every day.

Although psychological noise comes from the sound source, its distracting function works through human psychological factors. The more you pay attention to noise, the more you feel that it is disturbing yourself, the more uneasy and distracting you are.

Candidates should overcome the obstacles of psychological noise to the exam and ignore them. In this way, my impatience will be reduced and I can concentrate on the exam calmly.

With the approach of the college entrance examination, the task of study is getting heavier and heavier. Senior three students' anxiety level rises sharply and their mood is unstable. Any movement around them will affect their learning mood. This phenomenon is very common. Especially in the critical stage of preparing for the exam, how to effectively overcome all kinds of external interference and concentrate on efficient study has become a very serious problem. How to solve such a problem?

1. Control yourself with your will, or you can control yourself by limiting the time to complete the task. If you arrange your study tasks fully within the specified time, always remind yourself not to be distracted.

2. Master some psychological suggestion methods and communication skills. For example, when doing homework in a noisy environment, you can repeatedly say to yourself, "Let them make noise so that I can concentrate on my studies ..." You can also wear a walkman and listen to some lyric music to cover up the surrounding noise.

3. Develop good study habits. Senior three students can feel the harm of interference to their studies, and at the same time, they should consciously exercise their concentration in the disturbed environment.

4. Strive to achieve "five arrivals". The five senses are heart, ears, hands, eyes and mouth. When studying, senior three students will think in their hearts, their brains will keep thinking, their ears will listen, their mouths will speak, their eyes will see and their hands will move. When all parts of the body coordinate their movements, the brain is not easy to get tired.

Senior three students are eager to enter the ideal university, eager to improve their grades, often eager for success, blindly seeking more and faster, which makes their psychological load increase continuously. But when there is a contradiction between reality and desire, they will have anxious and impetuous psychological emotions. Once you have this kind of mood, you will often suffer from insomnia and anorexia, unable to study deeply, unable to calm down, and need long-term adjustment.

This kind of psychology is particularly prominent among students with average grades. Senior three students with this kind of psychology can take the following concrete measures to alleviate their anxiety:

1. Target incentive. Senior three students can set goals according to their own conditions, and regard them as the binding force of behavior and the lasting motivation of learning. Because a clear learning goal can not only control your bad behavior, but also constantly motivate yourself to make progress.

2. Cultivate your self-confidence. Self-confidence is the guarantee of success. Actively developing potential and believing that you can succeed are powerful internal factors for reviewing and preparing for exams, and are the fundamental guarantee for generating motivation. Only in this way can we face the college entrance examination, meet the challenges and be fearless.

3. Stabilize your emotions. Adjust your mentality, actively guide your psychology, and decompress scientifically. On the one hand, the best way is to communicate with your parents, your relatives and friends, let them know your thoughts and puzzles, let them care about and support you, and become the strong backing of your college entrance examination; On the other hand, I often talk with the class teacher and the classroom teacher. Through talking with the class teacher, I help myself to establish a correct outlook on achievements and life, and pave the way for my smooth entrance examination.

4. Establish a normal state of mind. A normal state of mind is an important guarantee to play one's level normally. Excellent students are always calm, don't catch fire, don't smoke and concentrate on their studies. The key is that they have a normal heart. I treat the college entrance examination with a normal heart, "peace of mind when something big happens" and "normal heart", so I should prepare for the exam with a normal heart.

5. Be the master of learning and improve learning efficiency. The best way is to make a reasonable and feasible study plan, make a scientific plan, reduce blindness, avoid following your feelings, and make your study orderly and busy, which is conducive to overcoming bad mentality.

6. Learn to cooperate with classmates. According to your own personality, hobbies, academic performance, etc. You can find the right classmates purposefully, help each other and improve your study together.

At the same time, senior three students should participate in activities organized by schools or classes, such as sports meetings, calligraphy competitions, holiday parties, debates and so on. In order to relieve their stress, stabilize their emotions and broaden their horizons. The study life is relaxed and full of energy, and I review with a good mental state to meet the exam.

Students in senior three often fall into emotional difficulties and find it difficult to dial by themselves because of their heavy study tasks, continuous exams and fierce competition. Here are some ways to relax.

1. If you are overwhelmed by your study and life, then you should resolutely refuse any extra overtime;

2. Have two intimate friends, whose personalities can be different from yours;

Don't feel too guilty after making mistakes, because everyone can make mistakes.

4. Face up to reality, because avoiding problems will only increase the psychological burden;

5. Don't blame yourself for "touching the soul" from time to time. This is actually a very stupid self-torture;

6. If you are wronged, you might as well tell your bosom friend;

7. Remind yourself that it is time to relax;

8. Less hard words such as "must", "have to", "must" and "absolute";

9. Some trivial things in life, let it be natural, don't take it too seriously;

10. Don't neglect your close relatives and friends, and apologize in time when you are sorry for others;

1 1. Don't bear too much "emotional debt", that is, learn to treat people rationally;

12. Let's regard setbacks or failures as an inevitable part of our life experience;

13. Before implementing a plan, it is best to anticipate the possible bad results in advance, so as not to be caught off guard because of "thinking too well";

14. When you are already busy, don't worry about extra things;

15. Look through the photo album often to relive the good times;

16. Always appreciate comedy, you should learn to tell jokes;

17. There are always some flowers in the bedroom, even if you pick some wild flowers.

18. Enjoy your favorite music;

19. Go for a walk in the park or garden;

20. Recall the happiest experience.
