Only when the teaching language meets certain standards and requirements can it play its educational and teaching functions and complete its educational and teaching tasks. Learning and using teaching language well is the basic skill of every teacher, especially primary and secondary school teachers should try their best to explore the inherent laws of teaching language and follow its basic principles. Teachers in a class should accept the knowledge they impart to their students and successfully complete their teaching tasks. First, the language should be correct and accurate. Correct. First, the language used should be standardized and the expression should conform to the scientific system of pronunciation, semantics and grammar. Second, it refers to the error that the language content has no knowledge. Every subject is a science. Ensuring correct teaching information is the basis for students to clearly understand the teaching content, and it is also the requirement of scientific language. It should be correct, complete and rigorous. Anyone who knows a little classical Chinese can interpret "walking" in "rabbit walking to touch plants" as "running". The correct understanding of "walking" was not completed until I got to senior high school, because our junior high school had little contact with classical Chinese. When the teacher explained that "rabbits walk to touch plants", he interpreted the meaning of "walking" as walking in modern Chinese, just let us imagine and understand that the rabbit's walking is running. The teacher's performance made us continue to understand "dying of a broken neck" with a grain of salt. After I really understood the meaning of "going" in high school, I was suddenly enlightened. Accuracy is another meaning, that is, the expression of language should conform to the objective facts or reality you want to express, and students should not be misunderstood or ambiguous, resulting in confusion of thinking. For example, the last paragraph of the text is the focus of the whole text: "The crow took the pebbles one by one and put them in the bottle. The water in the bottle rose slowly and the crow drank the water. " In order to guide students to understand this passage, the teacher gave them an intuitive demonstration. Teacher: This is a bottle with half a bottle of water. Here are some pebbles. The students pay attention to how I put the stone in the bottle. What happened to the water in the bottle? Please relate what you see to what you say. Health: The water in the bottle is rising slowly. Teacher: Just now, this classmate related what he saw, which was organized, but not accurate. Look again and see how the teacher put the stone in the bottle. Health: The teacher picked up the stones one by one and put them in the bottle. The water in the bottle rises slowly. Teacher: Yes! In the observation and comparison, you find that why do teachers "pick up" stones instead of "taking" stones? Why do crows "pick up" stones instead of "picking up"? Put the stone in the bottle instead of falling into it? Health: The stone is so small that people can pick it up with their hands. A crow can't pick it up without hands. If its mouth is sharp, hold it in your mouth and put it in the bottle. Health: If you put a stone into a bottle gently, you won't break the bottle even if you fall. ..... Teacher: So, the words should be accurate and conform to the reality of life. Accurate teaching language, examining every teacher's rigorous academic spirit and serious and responsible attitude are also the minimum requirements. Second, the teaching language should be popular and interesting. Popularization means making students easy to understand, simplifying and living the subject terms. Interest is to arouse students' initiative and enthusiasm, so as to achieve the ideal listening effect and improve learning efficiency. The reason why Zhao Shuli's Marriage of Little Black Boys is universally welcomed is because of its popularity. No matter in content or language form, the outstanding feature is popularity, which is loved by the people and easy to understand and accept. Mathematics is a highly logical and abstract science. For some highly abstract mathematical languages, using popular examples and explaining them in popular and natural languages can help students understand abstract mathematical languages. For example, when talking about the certainty of elements in a set, you can ask "all the college students in this class" if they can form a set. Most students answered "Yes". The teacher further said, "Then please stand up for this group of Datong University." At this time, some people stand up and some people hesitate. At this time, the teacher can explain: Why hesitate? Because they can't establish whether they are big or not, they don't conform to the certainty of set elements. That is, this set or any object or element that is not an element of this set must be very clear, so the above example cannot form a set. This explains the certainty of elements in the set, which is easy for students to understand. A political teacher talked about the essence of the capitalist system. In Fourier's vivid words, doctors want as many patients as possible, lawyers want every family to go to court, and architects dream of making a big fire, which will burn down 1/4 of the city. These words vividly summarize the essence of capitalism, and students find it vivid and interesting. A physics teacher introduced his class "Centripetal Force" in this way: "In acrobatic performance, there is a very thrilling program called" Flying Over the Wall ". Performers drive motorcycles up and down the inner wall of the frustum-shaped barrel, flying around like flies, and the audience is afraid that the drivers will fall. Why don't flying cars that "fly over the wall" fall off? Because drivers are physicists, they know centripetal force ",humorous language, attracted the attention of students. Teaching is an art. First of all, it embodies the art of language. Popular humor teaching can create a relaxed and harmonious teaching atmosphere and atmosphere, so that students can maintain a high mood of attending classes. A qualified teacher can't just be satisfied with lecturing or speaking clearly. The question is, do you understand, do the students understand and absorb it? Third, the teaching language should adapt to the age characteristics and knowledge level of students. Different ages have different abilities to accept and understand words. Pupils and junior high school students are young, lack of knowledge accumulation, incomplete cognitive structure, low level of knowledge and poor abstract thinking ability, which greatly restricts their understanding and acceptance of words. For example, they can't understand abstract, generalized and euphemistic language well. But positive thinking in images, concrete and intuitive thinking, activity, curiosity, curiosity and imitation. The language is vivid, simple, vivid and easy for them to accept, which is different for high school students. Due to the increase of life experience and the accumulation of knowledge, their abstract thinking ability has been greatly improved. They can explore the essence of things through phenomena and improve their understanding of teaching language, which is not limited to intuitive images, easy to understand and friendly to the language. Students of the same age show different physiological and psychological characteristics. In the process of language expression, teachers should pay attention to whether the language can be accurately understood and accepted by students in the choice of form and content. Teachers and students are the two-way connection between subject and object in classroom teaching, and teachers and students are the subject and object of each other. Through questions, answers, explanations and discussions, teachers directly participate in classroom teaching as leaders and students as learners. To make classroom teaching a lively learning process in which teachers and students participate together, teachers should start from students' psychological reality, care for and respect students, make friends with them, treat them as equals, and adjust their emotions to an appropriate state in the teaching process. Fourth, it is enlightening and instructive. Teaching language should enlighten students' minds and thinking, with correct humanistic ethics, noble sentiments and moral concepts, correct thoughts and healthy thoughts and feelings. For example, when learning logarithmic table in math class, the teacher took a piece of paper and said to the students: Students, the thickness of this paper is about 0.083 mm Now I have folded it in half for three times, and the thickness is less than1mm. However, if you fold it in half for 30 times, please estimate its thickness. After my calculation, the thickness is amazing and will exceed the height of Mount Everest 10. (The students were surprised and even suspicious, so they calculated in form: 0.083×230=? But I can't figure it out at once. Calculating 230 takes a lot of time and is easy to make mistakes. If we learn to use the logarithmic table, we can calculate the result accurately soon. This teaching example vividly tells us what heuristic teaching is and how teachers use it. Teachers' teaching language is to teach and educate people, and the ultimate goal is to educate people. Cultivating qualified talents who are useful to society is the ultimate pursuit of education. Therefore, the educational nature of teaching language is very important. The educational characteristics of teachers' language first require that teachers' language itself should be healthy, civilized and progressive, and vulgarity, vulgarity and backwardness are prohibited. In the process of teaching, "moral education" always permeates language practice. When a primary school teacher was teaching students the word "hit", some students said, "It's hitting people." The teacher immediately said: "It should be said that it is not hitting people. Can young pioneers hit people? " Small things reveal the truth, and teachers' moral quality and moral requirements are fully demonstrated through teaching language, which is an excellent example in line with educational principles.
