Changing mathematics teaching language is the key to improve classroom efficiency. The language of primary school mathematics teachers should be expressive, scientific and logical; Yaoqi
Wisdom, attaching importance to inspiration and thinking; To stimulate interest, we should pay attention to interest and visualization.
First, it is accurate, clear and scientific.
Mathematics is a rigorous and accurate science, and the expression of mathematical language must be rigorous and scientific. In primary school, students are laying the foundation.
The revelation of ideas, the analysis of problems and the elaboration of contents should be expressed in correct and scientific language. Scientific language should be thoughtful and rigorous,
The meaning is accurate, the wording is rigorous and there is no ambiguity. Only in this way can we correctly reveal the essential characteristics of objective things and let students have a clear understanding.
Otherwise, it will only make students doubt and even make mistakes in judgment, thus disturbing students' thinking.
Second, concise, sophisticated and logical.
Teaching language should be concise, clear, neat, not sloppy, not repetitive, concise, comprehensive and meaningful. Students should not only
Easy to accept and remember. The teaching language should be more logical, coherent, closely linked and distinct, and should not be disturbed.
Post-contradiction. For example, an isosceles triangle is defined as a triangle with two equal sides. Don't change it to "two isosceles triangles" at will, one for the other.
Word, made a big mistake against logic: circular definition.
Third, the guidance is instructive.
The value of teaching lies in guidance and enlightenment. Mathematics teachers should be good at giving appropriate guidance and urging students with inspiring language.
Use your head and actively explore ways to solve problems. For example1/6+112+1/20+1/42 =? Use conventional methods to communicate.
Division is very complicated. Just when the students are reluctant, the teacher points out the maze: Look, what are the characteristics of denominator? Can you change it,
Calculate in a simple way? Under the guidance of the teacher, the students observed that the denominator is the product of two consecutive natural numbers and associated it with1/2-1/3 =1/6.
1/3-1/4 =1/2,1/4-1/5 =1/20,1/.
Teachers' use of heuristic language can not only open students' thinking, but also cultivate students' creative association ability.
Fourth, activate thinking and use thinking.
Teachers should be good at using philosophical and rational language to activate students' thinking and pave the way for students to think and solve problems. Classroom teaching
In learning, we should ask questions on the key points of knowledge, the difficulties of understanding, the turning point of thinking and the exploration of laws for students to think, answer and guide.
Students' thinking gradually expands and their understanding gradually deepens. For example, when teaching "Divider is the division of decimals", let students review the old knowledge first 10.25÷ 125.
Then transition to 10.25÷ 12.5, and ask: (1) What's the difference between these two questions? (Thinking turning point) (2) How to turn it into a divisor?
Is it a division calculation of integers? (Key points of knowledge points) (3) If you want to keep the quotient unchanged, what should you do with the dividend and according to what? (Legal Search Center)
(4) How to calculate the division with a complete summary and a fractional divisor? (difficulty in understanding)
V. Humor and vividness
Teachers should use interesting teaching language according to students' psychological characteristics in class to make teaching interesting. This requires teachers to use it in class.
Language should be vivid, so that students can reach the other side of knowledge with laughter unconsciously. Of course, we should emphasize the vividness of the teaching language.
Image and humor should pay attention to the purity of language and be lively.
Six, concise and easy to understand, with the image
The so-called conciseness means that teachers' language should conform to the characteristics of mathematics and try to express the richest content with the least sentences. If you're talking about.
When judging by examples, tell the students that without too many examples, only one counterexample can explain the correctness of the sentence.
The so-called easy to understand means that the teacher's language should be a language that students can understand and understand, and should be in line with the age characteristics of students. The teacher is organizing the lower grades.
The language used in mathematics teaching should pay more attention to childlike innocence, which is easy for students to understand and accept, otherwise it will not play a role in organizing teaching. Just for
Pupils, teachers' daily language should be vivid, easy to understand, simple and childlike, such as "children, please listen carefully and ask grandpa knowledge to tell you a truth" and other languages that meet the characteristics of children can organize the whole class teaching well.
Primary school classroom teaching language should also avoid adult and vernacular culture, put an end to language errors, and pay attention to standardization and demonstration. For example, "3728" cannot be pronounced.
"3728" should be pronounced "3728".
