1? Carelessness is worse and more hateful than ignorance. When doing exercises, a question can't get the correct result. There are usually two reasons. The first one is completely because I don't know. In another case, some children often do more than 0 when they do the problem; 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 write a wrong word ... in short, it's not a mistake because you don't know (you and your children should think about how many kinds of carelessness there are). The most regrettable thing is that when parents guide their children to learn, they often criticize and accuse them more severely when they see that their children can't do a topic. "How did you do that? You can't even do such a simple topic? ! "But if you are deducted for carelessness, you will often say in a more gentle tone," Alas, why are you so careless? If so, won't you do the right thing? " "Pay attention next time!" As everyone knows, different attitudes towards these two different phenomena make children relax their vigilance against "carelessness", ignore the analysis of "carelessness" and weaken their understanding of the harm of "carelessness". Rousseau has a wise saying: "People make mistakes not because they don't understand, but because they think they know everything." 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." We are not afraid of "ignorance", because we can learn what we can't learn and understand what we don't understand. "Carelessness" is terrible, because children 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. So carelessness is worse than ignorance. Carelessness is caused by ignorance of carelessness. 2? Carelessness will form habits, and once it is formed, it will not change. Because of the neglect of "carelessness", carelessness appears again and again in learning, and slowly "carelessness" becomes an inertia, but I still can't understand it clearly. Many students have experienced such a situation. After a semester of hard work, they thought their exam results should be good, but the results were not satisfactory. Many of them are caused by "carelessness". Although they are just "careless", unsatisfactory grades often make them lose confidence in themselves, and they will think that no matter how hard they work, their academic performance can't be improved. Then at this time, children's self-confidence will be gradually hit, and they will gradually lose their confidence and interest in learning. Just think, how can "lack of fighting spirit" succeed? Therefore, once "carelessness" becomes inertia and habit, it can never be changed. The phrase "a leopard cannot change his spots" is too familiar to everyone. Why do some people always lose their keys and wallets when they grow up? As long as you pay careful attention, anyone who has a successful career is not rigorous and meticulous, even those who look casual are "careless" There is a famous saying in ancient Greece that "character is fate", so how is character cultivated? This is a habit! So how is the habit formed? Just over and over again. This is why educators emphasize one point-"We should form good habits from childhood"! So "carelessness" is easy to form a habit. If misfortune becomes a part of your personality, the possibility of success will be greatly reduced. 3? Carelessness is not wrong, it is wrong! ! ! When parents talk about or criticize their children, they often say: My child's biggest shortcoming is carelessness ... Everyone has shortcomings, everything has shortcomings, and the world is not perfect. Because of 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. To sum up, if you want to solve the careless problem, if you don't have enough correct and clear understanding in your mind, then the careless problem can't be solved well. It will appear at any time like a ghost, destroying what you have achieved and hindering what you may achieve. Although the consequences of "carelessness" are sometimes not great, in any case, we should be very vigilant and serious about "carelessness". Because "carelessness is a mistake", if it is a mistake, it should be corrected rather than explained! Therefore, our attitude towards "carelessness" should be-Ning Zuo should not be right! 4? The phenomenon of "carelessness" is by no means "writing wrong words", but "copying wrong lines" As we mentioned earlier, there are usually two reasons for making mistakes in a topic, one is ignorance and the other is carelessness. Many students have had this experience. They had a problem and couldn't figure it out after thinking for a long time. At this time, others gave a small hint. Well, they're almost done. Also, I can't remember it during the exam, but I remember it when I leave the examination room! What is this phenomenon? You can't be a child. You still feel wronged! Can you count? But it's not! Therefore, many students are very pleased to say to themselves that they are "careless" and have not been well thought out, so they have not made it. In fact, it is impossible to solve the problem correctly because of the lack of mastery and understanding of the concept! It is a "blind spot" in learning, and how many such key loopholes in learning are often covered up by the word "carelessness". After the above situation, the child's reaction is even more indifferent, and the past is over! This is a daily - happened thing. Think of "ignorance" as "carelessness" and think about how terrible it is! 5? How to solve "carelessness"? Having said so much about the dangers of carelessness, it's time to find a way! We should classify, summarize and analyze "carelessness" first, and then think about countermeasures. Let's look at the case in the question first, and how to analyze the phenomenon of "carelessness"! Topic: 10 people can plant 5 trees per hour. /kloc-How many trees can be planted in 0/0 hour? Wrong solution: suppose X trees are planted. The first type: X= 10×5× 10=500 carelessness; The second type: X= 10×5=50 (tree); The third type: X=5× 10=50 solution: x trees were planted. X=5× 10=50 (tree) A: 10 People can plant 50 trees in 10 hour. Analysis: wrong solution 1: multiply the numbers blindly, sometimes because you don't carefully examine the questions, and sometimes because you don't understand the meaning of solving the problems at all. Wrong solution 2: it is not "10×5" but "5× 10", which seems a bit picky, but it shows that you should have a good quality in the process of doing the problem. Doing the problem is not only to get the correct answer, but also to express your thoughts accurately and perfectly. Myth 3: I obviously forgot to write the unit, which is incomplete. (User: It is not a wrong solution, because there is a unit when setting. If you add the unit, then x=50 (tree), and the answer is: 10 People can plant 50 (trees) in 10 hours. It can be seen that the author is careless and everyone takes it as a warning. The first two mistakes are not really "careless", but are often evaluated as "careless" (parents and teachers should pay special attention to this). Appearing in this simple topic seems to have no influence on the overall situation, and it seems to be corrected in one sentence, but after the advanced stage of learning, the thinking may be wrong because of this deviation. This is also why many students are thinking hard when doing the problem, although others can understand it with a touch, because they don't grasp enough details. But over time, I have less and less confidence in my ability to solve problems and feel more and more helpless. The key reason is that such students often think they understand, but in fact they don't really understand and master the basic concepts. I have had many such experiences in tutoring students. When students got a seemingly complicated topic, they said to me without thinking: teacher, I can't do it. I said, review the questions again. But the students will still say: teacher, I can't watch it. In fact, the problem is not difficult, but students lack confidence in solving the problem. When our parents and tutors encounter this kind of situation, they often act very proud and comfortable and explain it to the students in detail. As everyone knows, this is harmful to students. Be sure to put in neutral when parking, and don't forget it carelessly. The third is typical "carelessness", but people often don't care. There are many kinds of carelessness like this, but they all have one characteristic, that is, the form is relatively simple and often repeated. This is the true meaning of "carelessness", which is not a mistake of "carelessness". We discuss it in another chapter. The analysis method of "carelessness" is clear. What should we do next? First of all, make a summary of all the "carelessness" phenomena that have happened to you. Of course, it must be very specific and detailed. In view of the "carelessness" phenomenon that students often write typos, we made a statistic. No student is considered as the "king of typos". At most, there will be more than 20 typos, and more typos are often caused by unfamiliarity. There is a fifth-grade child, and there are typos everywhere in his exercise book and composition book. Parents are discouraged by this, and the children themselves feel confident. Together with my child, I sorted out all the typos in his book and counted them out. Children themselves and their parents find that only a few words are always misspelled. This is a surprise, I never thought of it! After sorting out the typos and explaining some of them in detail, such as the typical careless classification of "Xiang" as "already doing", the reasons that often lead to the wrong use of "De", "Di" and "De" are more because the usage of "De", "Di" and "De" is not grasped in essence. After carefully and patiently listing and analyzing the typos, one week later, the number of typos in the student's composition was reduced to only three, which surprised him and his parents, because it was so rare and difficult for their children to have three typos! As long as we sort out the "carelessness" in detail, we can strengthen these phenomena ideologically and consciously. In the future, when students encounter this phenomenon in a similar environment, the brain will automatically give an early warning and response to curb the "carelessness" phenomenon to the maximum extent. For example, everyone knows to be careful when walking on ice, because it is slippery. Similarly, if you encounter a similar situation that you may not be careful, just like walking on the ice, you will become cautious. The possibility of making mistakes will naturally be much less. In fact, solving "carelessness" is like walking on ice. Be careful, because you have fallen on the ice, so you will remember it, unless you have fallen on the ice, you have no impression! As long as you face "carelessness" with your heart, it will soon disappear from your sight. Although this does not completely guarantee that you will not make low-level mistakes, it can well reduce the error rate caused by "carelessness" and naturally improve the quality of problem solving and learning efficiency. Of course, the main way to solve "carelessness" is to check. According to the research of scientists, it usually takes 20 days to form a habit. After reading this sentence, I think you must have confidence and determination to eradicate bad habits and establish good habits! For you and your children, there is only plain and improved understanding, and there is no habit that cannot be overcome. At present, the most effective classic solution to "carelessness" is "3A win-win training". Interested friends can log on to www.e 100.com.cn to get rid of carelessness. Be calm when you do the problem, not impetuous. 2. Try to do the questions in different ways when checking. 3. Every time I make a careless question, punish myself, or write down the reason of the problem, I usually read it several times, or warn myself and say to myself: it's not that I can't. If everything I know is wrong, what can I do? A person who is not serious and responsible can't achieve great things. I am still young. I must overcome it and let me study and live better. I will succeed. Carelessness is not my patent. It can't control me. I have to get over it. 4. In daily life, start with small things and take everything seriously. Every day, try to do everything well. Stick to it, so as to overcome the problems of impatience and panic. 5. Develop the habit of careful inspection. When you finish your homework or answer the paper, remind yourself repeatedly in your mind that you must carefully check every question, read it carefully, concentrate on it, do your homework correctly and answer the paper well. By reminding yourself repeatedly, you can gradually develop the habit of being patient and meticulous and overcome carelessness.

In fact, I am also a careless pupil. In the math exam, I often leave my 100 because of carelessness. Sometimes, there are several reasons for carelessness: 1. The draft paper is not carefully written. In view of this, our math teacher did a very good job. She asked each of our classmates to prepare a draft book for regular inspection and evaluation. Those who behave well will get a little reward. 2. Wrong number. This problem is more serious, so it is better to do your homework seriously, seriously and seriously again. Sometimes necessary punishment is taken: copy concepts and numbers (it is best not to copy more, just warn).

The specific scheme is as follows:

In order to cultivate children's financial quotient, the teacher designed * coins (you can choose the number of *), so that students can design the shape and appearance of * coins. Every day, a certain number of * coins will be awarded according to students' performance. When a certain number of * coins are accumulated, teachers will reward them, and there will be different prizes every month. Our teacher really takes great pains, although he is not a rich boy. ) We will try to form all kinds of good habits for a worthless prize. After a long time, these good habits will take root in us, and there will be few carelessness or other problems from then on.

If students just don't listen to advice, they have to use "hard methods" to let parents check more and circle the wrong questions. In the future, they will always examine why they made mistakes and learn to reflect on themselves. This is also one of the main points of teaching.
