First, educate students from the formation of habits.
Correct calculation is the foundation of primary school mathematics and the premise of correct calculation and reasonable calculation. When students make mistakes in calculation, their reason is "carelessness". For example, the title is misread and copied incorrectly, the handwriting is scribbled, 0 and 6 are unclear, 1 and 7 are interchanged, 4 and 9 are mixed, and the columns are vertically misplaced. What is the reason for "carelessness"? First, the child's physical and mental development is immature, and second, he has not developed good study habits. It is the duty of teachers to guide and promote children's physical and psychological development and cultivate good study habits. Developing good study habits from childhood will affect a child's life. Therefore, cultivating students' good study habits is the requirement of quality education and the premise of improving calculation accuracy.
In teaching, we should cultivate students' careful and meticulous homework, neat handwriting, standardized format and develop good habits of introspection. Teachers should first demonstrate and set an example. Writing on the blackboard and correcting homework should be standardized and tidy, which will exert a subtle influence on students. Secondly, students' homework should be strictly trained according to the requirements of the specification. In a word, it is an eternal task for teachers to cultivate students' good study habits.
Second, the importance and training of verbal arithmetic
1. Basic oral calculation must be correct and skilled.
The addition and subtraction within 10, the addition and subtraction within 20, and the multiplication and division of one digit are the basis of the four operations, and 100% must be correct and proficient in verbal calculation. Teaching AIDS and learning tools should be used in teaching, so that students can understand arithmetic and master the law of calculation. For example, when teaching one digit plus one digit, in addition to the teacher's demonstration, students should also be allowed to operate with learning tools and know how to "ten into one". In multiplication, let students know that multiplication is a simple operation of addition, and division is the inverse operation of multiplication. And can use multiplication formula freely.
2. Stick to oral arithmetic training every day.
Every time the preview bell rings in math class, students will naturally and quickly train according to the oral calculation matched with the textbook. The math class representative will pick up the dictation card and let the whole class read the card to practice, "drive the train", and sometimes listen and calculate. This intense and orderly training aroused the students' interest. They made a copy of the card made by the teacher and read it to their parents after school. With this accumulation and persistence, students' calculation speed and correct rate are obviously improved, and parents also agree with this kind of training.
Thirdly, in order to improve the accuracy of students' calculation, some countermeasures have been taken.
1. Strengthen ideological education and improve calculation accuracy.
Students forgive their "carelessness" after discovering their own calculation mistakes. In order to have a correct learning attitude, I ask students to do two things after I finish my homework. (1) statistical calculation error. (2) Find out the mistakes and analyze the reasons. Through the statistics and timely analysis of errors, students find that almost all errors are not errors in calculation methods, but are caused by some bad habits such as not carefully examining questions, doodling and not checking. I circulated some books with high calculation accuracy and serious words to my classmates, asking them to introduce their learning experience, which made some students change their minds to some extent and also produced a desire to improve the calculation accuracy.
2. Make students master the operation process of calculation.
With the desire to improve the calculation accuracy, we can only make a good start, and more importantly, we should teach students the methods to improve the accuracy. Elementary arithmetic with the highest error rate should enable students to master the following operating procedures. Start the operation → concentrate on copying the questions carefully → carefully examine the questions and determine the algorithm → correctly apply laws and regulations → check step by step and correct them in time → finally get the results. In the process of training, the pace should not be too fast, and the amount of practice should be small and precise, so that students can have time to operate according to the operation, realize the superiority and enhance their learning confidence.
Three methods of correcting homework
Homework should be few and precise, handwriting should be neat and calculations should be correct. My measures are: correcting is to see if all the students' homework is correct and make an evaluation. If mistakes are found, they should be sent to students for self-examination and corrected after finding them. In this way, students will develop a good habit of correcting mistakes and cultivate their serious and responsible learning spirit.
In short, the formation of students' good computing ability is based on strict requirements and strict training. The second is to teach students some correct and effective calculation methods. The third is active education and encouragement. After taking countermeasures, students have established confidence in correct calculation psychologically, and strive to achieve correct calculation in behavior. The formation of this learning psychology promotes the improvement of students' correct calculation ability. Originated from network sharing. . .
