Browsing the blog at night, I found that some parents are also worried about their children's careless mistakes. Yes, good habits are the cornerstone of success. If you don't have a good habit to lay the foundation, you won't learn anything in the future. "Careful" is actually a habit, which is related to personality, but it is not innate. All habits are acquired. First, we should cultivate children's habit of "concentration", be serious and focused, be able to concentrate quickly, be able to control themselves to calm down, be half-hearted and not anticlimactic. The second is to cultivate children's habit of "checking" and get used to checking after doing things. For example, after the work is completed, check how it was completed. I'm finished packing. Check to see if there is anything missing. After finishing your homework, check whether there are any mistakes ... If you form the habit of "checking", you will benefit for life. We should develop the habit of "being orderly" and "being organized", behave in an orderly way, keep things in an orderly way, be not impetuous, and never forget things. Habits are not formed overnight, but the result of perseverance. Children cannot form their own habits, but the role of environment and education. First of all, adults should set an example and infect children with their care. If the whole environment is careful, children will naturally be careful. Parents should also pay special attention to the requirements of their children and stick to them. They can't be loose and tight, they can't forgive without principles, and they can't clean up the mess instead of children. Problem analysis There are many reasons why children are careless. In a child, carelessness often has several manifestations, and these manifestations are not static. For example, in a test, classmate A showed that he didn't pay attention to these problems. In the next exam, he still didn't carefully examine the questions, but there was nothing wrong with advancing and retreating, just forgetting to fill in two blanks. Children's carelessness will change with the change of physical and mental state and environment, and the degree of carelessness is still inconsistent. Anyway, carelessness is carelessness after all. No matter how and to what extent it appears, children can't escape carelessness. After investigation and consulting materials, combined with my own teaching experience and understanding, I think the main reasons for children's carelessness are: 1, thinking set's Educational Psychology points out that thinking set is a habitual psychological preparation state formed by previous activities, which will make people think or solve problems in a relatively fixed way. This mentality has its positive side, but it also has its negative side. The negative effect of primary school students' mindset in calculation is mainly manifested in the interference of old and new rules, resulting in "cumulative error" If addition is regarded as subtraction, subtraction becomes addition. 2. Perception of rough primary school students to calculate, first of all, they must perceive the formula composed of data and symbols. Because the characteristics of primary school students' perception of things are relatively general, rough and not specific. At this stage, students' perceptual development level is relatively low in selectivity, understanding and integrity. Therefore, they often only pay attention to isolated phenomena, but can't see the connection and characteristics of things, so they lack the integrity of the formula in their minds, and the calculation itself is monotonous, which is easy to cause psychological fatigue. At this time, when you encounter similar or similar numbers and symbols, you often start to calculate before you see them clearly. Operation sequence error, symbol error or data error. Of course, mistakes have a lot to do with the immature development of primary school students' attention level. At this time, the attention quality of primary school students is still not good enough, and the attention distribution is poor. For example, when they calculate correctly on their own draft paper, they often make mistakes when copying the answers into the questions. The stability of attention is poor, and primary school students lack the ability to concentrate for a long time, so students are often absent-minded when answering questions. Generally speaking, the older you get, the less likely you are to be careless. 3, memory errors and omissions A calculation problem often involves multi-step calculation, and the middle number needs short memory. However, due to impatience, hurry and fear of trouble, some of the stored information disappeared or was temporarily interrupted, resulting in "memory errors and omissions". 4. Emotional instability Pupils' emotions are not stable enough. Different emotional states will directly affect the process of mathematical calculation. Students want to calculate correctly and quickly. Because of their strong motivation and desire for success, they often have the opposite effect. Simple formulas are paralyzing and contemptuous; The calculation is complicated, but it also shows boredom and fear of difficulties, which leads to mistakes. When students are in poor health, they are more likely to be afraid of difficulties. After careful observation, it is found that junior one students are prone to fear of difficulties in mathematics learning, especially in the difficult spatial graphics and time understanding (in fact, they did not carefully examine the questions or listen to the teacher's reading aloud). When they are afraid of difficulties, they don't know how to solve them through repeated observation and identification, but they like to scribble and fill in. Their performance is like telling you, "I'm not incompetent, I just don't do it carefully." This is a false carelessness. Solution (1) Strengthen the examination training and accurately perceive the formula. To cultivate computing ability, we should first start with perceptual formulas and do a good job of basic training in examining questions. When designing calculation questions, we should deliberately create various types of questions so that students can fully perceive and be good at discovering the characteristics of calculation formulas. You can choose the ones that students are most likely to confuse, and carry out concentrated comparative exercises to cultivate students' observation and attention. Adhere to this kind of training, cultivate students' awareness and ability to perceive the characteristics of formulas, and lay a good foundation for choosing reasonable algorithms. (2) Persist in oral arithmetic training and cultivate memory ability. Skilled oral calculation is the basis of correct written calculation, and both oral calculation and written calculation are inseparable from instantaneous or short-term memory. Oral arithmetic is the best form to train students' short-term memory ability, so oral arithmetic training must be regular. For example, the teacher dictated the topic, let the students listen and let the students count. Students should not only remember the topic, but also remember the intermediate process. Or students can look at the problems on the card and make visual calculations. If oral arithmetic training is monotonous, students will get bored. Especially junior children, in order to avoid boredom, they can adopt various lively forms, such as "driving a train", "relay race" and "checking passwords". This perseverance not only cultivates students' short-term memory, but also cultivates students' good attention quality. (3) Pay attention to non-intelligence factors and develop good study habits. Students' good study habits are the starting point of mastering learning methods, improving students' ability and strengthening quality training, and the premise of improving computing ability. In teaching, we should educate students to establish a sense of responsibility and self-confidence, cultivate carefulness and patience, strive to solve problems one by one, be brave in facing difficulties, be diligent in thinking and finish independently. Students are required to carefully examine the questions, see clearly every data and operation symbol in the questions, check up and down, left and right in every calculation step, and accurately copy the data and symbols; Cursive writing should also be neat and clear for easy checking. If you can't do verbal calculations, you must write down the calculation process clearly. After the calculation, we should consciously check whether the calculation process is reasonable, whether the calculation method is simple and whether the calculation result is correct, and cultivate students' habit of checking. It can not only improve the accuracy of calculation, but also promote the intellectual development of students through training. It is impossible to improve students' computing ability overnight, but it is a long-term and meticulous training process. However, as long as children's cognitive rules are followed and hard training is carried out, the careless calculation of primary school students can be overcome. Conclusion To sum up, the reasons for students' carelessness are mainly related to their low level of physical and mental development, bad study habits and the influence of the surrounding environment. With the growth of age, the carelessness caused by the low level of students' physical and mental development and the influence of the surrounding environment will become less and less, and the reasons caused by bad study habits will become more and more obvious. In other words, some carelessness is only a temporary phenomenon of children at this stage, and carelessness caused by bad study habits may really affect students' long-term study life. Therefore, we should pay more attention to students' good study habits and attitudes, which not only teachers should pay attention to, but also parents should pay more attention to their children's growth in these areas. Parents should have a correct and comprehensive understanding of their children's carelessness. Generally speaking, the main reasons for carelessness are as follows: 1. Children's visual recognition and memory ability is not strong, and mistakes will inevitably occur in reading or writing. 2. If you don't pay enough attention, your heart is here and your mind is there, then you will inevitably make mistakes. Sometimes some seemingly careless mistakes are actually caused by poor foundation, poor knowledge and unskilled answering skills. 4. Too many tasks, impatient children, will also cause carelessness. 5. I didn't develop the good habit of correcting mistakes in time. Teachers and parents usually help me check my mistakes and correct them. My child has not developed the good habit of checking and correcting mistakes in time. Many children have developed a careless habit in their usual study, mainly because they have to be checked by teachers and parents when they do their homework, and they have no good habits and sense of responsibility. Therefore, children are careless in exams, and parents should also reflect. We should use the right methods to help children minimize mistakes caused by carelessness. 1. Parents criticize their children casually on the grounds of carelessness, which is easy to cause psychological pressure on their children. During the examination, they will focus on psychological requirements such as "I don't want to be careless", which will easily lead to distraction and more unnecessary mistakes. For children's carelessness, parents should try not to take positive punishment, and can adopt positive reinforcement. For example, don't criticize a child when he is careless, but when he finishes something seriously, parents should praise him in time and strengthen his carefulness, so that the child will gradually accept this psychological suggestion and develop more and more carefully. 3. Help children develop the good habit of checking homework in their usual study. Many parents are willing to check their children's homework, thinking that they are responsible for their children, but they don't know that their children will develop the habit of not checking carefully. To get rid of their carelessness, we must first start with our parents. 4. In daily life, parents should infect their children with their care, such as keeping the house in order, suggesting that children learn to tidy up their own things, tidy up their own rooms, and cultivate their sense of responsibility for their own affairs. 1. In order to overcome carelessness, we should pay attention to what we must 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. 2. 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. 3. 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 would like to introduce you to an exercise method: threading needles and holding beans with chopsticks. With the improvement of proficiency, we will gradually increase the number and difficulty of practice. I hope that parents can help their children develop careful quality through the above contents.
