First, pay attention to non-intellectual 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. For example, the rationality of the operation result can be judged by estimation. Additional operation
, and should be greater than each addend; In subtraction, both difference and subtraction should be less than the minuend. Another example is to teach students to test according to the relationship of the four operations and calculate 9524+7689 = 172 13, so as to check whether the calculation result is correct according to the relationship of the addition part. Therefore, cultivating good inspection habits can not only improve the accuracy of calculation, but also promote the intellectual development of students in combination with 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.
Second, strengthen the training of examining questions and accurately perceive formulas.
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, and we can choose the ones that students are most likely to confuse for centralized comparison exercises. Such as 3/5 × 3/5, 3/5+3/5, 3/5+2/5, 3/5 × 2/5, to cultivate students' observation and attention. The focus of examination training is the operation order, whether the algorithm can be used for simple calculation, and what method is more reasonable to choose in the elementary arithmetic problems of fractions and decimals. The training method is: first observe and discuss, then calculate, and finally exchange calculation methods and comment on which method is more reasonable and flexible. What are the characteristics of observing the following questions? (how to calculate it is relatively simple? ) 2 1.6 ÷ 4/25, 85÷9×6, 44/45 ÷ 35, ( 1.25× 0.39× 8.4) ÷ ( 1.3× 0.75× 0.
Third, let the children prepare a wrong book.
Children's exercise books and composition books are full of typos, which makes children feel inferior and teachers feel helpless. So, the child's teacher went to consult a child education expert, and under the guidance of the education expert, the teacher came up with a good idea. She counted and sorted out the typos in his exercise book with the children. After finishing, she and her children were surprised to find that only a few words were always written wrong. Finally, she asked the children to prepare a small notebook, write the sorted typos in this notebook, and analyze the reasons for these typos with the children and write them in the notebook. With the patient guidance of the teacher and the earnest persistence of the children, after one week, the typos in the children's exercise books have been significantly reduced. If your child has a careless question, you might as well ask him to prepare a wrong book. In fact, as long as the problems of "carelessness" are sorted out in detail, these problems can be consciously corrected ideologically. When children encounter similar problems in the future, the brain will automatically give early warning and response, so that,
The phenomenon of "carelessness" can be controlled to the maximum extent. Like walking on ice. Because the ice is slippery, you should walk carefully. Because you are careful, you will naturally make fewer mistakes.
Fourth, cultivate children's neat and orderly living habits.
Children's carelessness was not developed in a day. If a child lives in a disorderly environment since childhood, without a certain schedule and good living habits, then the child is careless in doing things. Therefore, teachers should guide children to develop orderly living habits. In life, let children develop the good habit of keeping their belongings, not only school supplies, but also clothes, shoes and so on. In learning, it is necessary to cultivate children's good habits such as completing homework on the same day, checking after finishing homework, previewing before class and reviewing after class. Life and study are carried out in an orderly way, and carelessness is of course a very rare phenomenon.
In a word, the reasons for students' carelessness are mainly related to their low level of physical and mental development, poor 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.
