Only by learning relevant mathematical terms and symbols and correctly analyzing logical relations according to mathematical principles can we truly understand books. At the same time, mathematics has its accuracy, and every mathematical concept, symbol and term has its precise meaning. So math reading needs careful thinking. In order to really learn mathematics well, implement the goal of mathematics quality education and make mathematics no longer difficult to learn, I think we must attach importance to mathematics reading, which is actually a very simple truth-people who read more books have better oral expression ability and composition level than those who read less.
Second, cultivate students' ability to understand mathematical language
To cultivate students' language expression ability, we must first cultivate students' ability to understand mathematical language. Such as understanding the concepts of sum, difference, product, quotient, expansion and contraction, we should not ignore the defects in students' language. For example, ask: how to sum? Complement+complement = sum, know and find one addend, use and subtract the other addend. Another example is the movement of the decimal point. Move the decimal point to the right, the number will be enlarged, move it to the left, and the number will be reduced. If you know that the decimal point will move to the right when the number is enlarged, then the decimal point will move to the left when the number is reduced.
Third, the teacher's model language is a role model for students.
Children have strong imitation ability, and teachers' mathematical language directly affects students' mathematical language. Therefore, teachers' language strives to use words accurately, concisely, clearly, coherently and logically. This requires teachers to constantly improve their language literacy, and through the exemplary role of teachers' language, it will have a good influence on the formation of students' initial logical thinking ability.
Fourth, let students develop mathematics language in various forms.
1. Communicate at the same table. It is very convenient to communicate at the same table, and it is also a good way to let students express their opinions and cultivate their language ability in classroom teaching. Especially in the new teaching, students have mastered certain methods, which need to be summarized in time. Let the students master their ideas and use them flexibly through the exchange of a few simple words at the same table.
2. Group discussion. Select team leader, recorder, etc. In the group discussion. When there are difficulties in learning, students can be invited to discuss in groups, and representatives can communicate after the discussion. By doing so, every student has the opportunity to speak and listen to others. Have the opportunity to express their views in front of several people and the whole class.
4. Talk while doing. After the teacher demonstrates, let the students say the method and draw at the same time, so that they can master the method and drawing method well. Only by organically combining hands-on operation, brain understanding and verbal expression can we promote the effective transformation of perception into internal intellectual activities and achieve the purpose of deepening knowledge understanding.
5. Class summary. There are two kinds of classroom summary: teacher summary and student self-summary. Summarization can improve students' comprehensive generalization ability and clearly recall the main points of this lesson. Although the expression ability of primary school students is limited, it can be correctly summarized as long as it is correctly guided.
Fifth, train students to speak persistently.
At the beginning, we should grasp every teaching link, combine the teaching content, carry out oral training in a planned, purposeful and conscious way, and guide students to talk about reasoning, thinking, solving problems, calculating and analyzing in mathematical language. In the lower grades, students can be asked to think before speaking and express themselves in complete sentences. Middle school students can be asked to express their thinking process in an orderly and coherent way. Senior students can be required to use mathematical language gradually to express accurately, concisely and realistically. Through training, not only the students' expressive ability of mathematical language is improved, but also the accuracy of their thinking is cultivated.
In teaching, teachers should seize the opportunity to provide students with language expression, pay attention to the cultivation and training of mathematical language, use mathematical knowledge and mathematical thinking methods to solve practical problems, and follow suit to cultivate students' language expression ability and application ability, so that students can form a good habit of using mathematical language scientifically.
