How to use mathematics teaching language in primary school mathematics teaching
In mathematics teaching, we must give full play to students' initiative and enhance their awareness of participation, communication and cooperation. All this is inseparable from language. The accuracy of language reflects the rigor of thinking, the continuity of language reflects the logic of thinking, and the diversity of language reflects the richness of thinking. Mathematics learning activities are basically mathematical thinking activities, and mathematical language is a tool of mathematical thinking, so mastering mathematical language is one of the important foundations for carrying out mathematics learning activities smoothly and effectively. It is necessary to closely combine the cultivation of students' mathematical language with the study of mathematical knowledge as an important part of mathematical learning. Only in this way can students' thinking be better organized, logical and accurate. It is particularly important to cultivate students' mathematical language expression ability, so it is very necessary to cultivate students' mathematical language expression ability in primary school mathematics classroom teaching. At present, many math teachers have clever teaching designs and wonderful classes, but what they lack is the agility of students' fluent answers, and the classroom is difficult to be active, and the interaction between teachers and students is difficult to achieve the teachers' expected goals. Due to regional differences, students don't know much about the world, communicate with others and lack the ability to express themselves. How to cultivate children's mathematical language expression ability in practical teaching is a problem worth pondering, which plays a key role in comprehensively improving the quality of primary school mathematics teaching. How to cultivate rural primary school students' language expression ability in class? I tried from the following aspects in my teaching activities: 1. Stimulate students' interest in learning mathematics and make students "think" that interest is the best teacher. In order for students to "melt" themselves into mathematics classroom activities and express their views consciously and actively, we must first stimulate students' strong interest in learning and desire to express themselves. Practice has proved that the more interested students are in what they have learned, the stronger their sense of participation and the more active their thinking. In teaching, we should pay attention to using various forms to attract students' attention, stimulate their interest in learning and make them think and speak. First of all, let students experience the beauty of mathematical language and stimulate their interest in speaking. Mathematical language looks bland on the surface, but in fact it has its own distinct characteristics, that is, accuracy, strictness, conciseness, rich connotation and inherent aesthetic feeling. If we fully understand and master it, we can appreciate the subtleties and feel the artistic conception of beauty, thus arousing interest in learning and exploring. For example, when teaching division, the expression of remainder: the remainder must be less than the divisor, and students often say that "the remainder cannot be greater than the divisor". Teachers should guide students to compare and understand the differences between the two statements, deeply appreciate the rigorous beauty of mathematical language expression, and feel the importance of mathematical language expression to stimulate students' desire to speak. Secondly, let students feel the fun of language expression and experience the fun of expression. Only by constantly encouraging students, their language expression can be completely consistent with their fluent thoughts, their wisdom and creativity can be fully released, they can feel the pleasure of success, and they can also have the desire and interest to speak freely. Therefore, in the classroom, we should try our best to create an opportunity for students to show their talents, adhere to the principle of facing the whole and grasping the few, and consciously ask students at different levels according to the difficulty of the questions and encourage them to answer: let some students with learning difficulties answer the questions, even if they are confused, give priority to encouragement, and then ask other students to supplement them, so that underachievers can make up for their shortcomings with the strengths of others and deepen their memories without fear. Excellent students answer some thoughtful questions and arrange medium students to answer less difficult questions. In this way, the enthusiasm and initiative of each student are mobilized, and the thinking level and expression ability of all kinds of students are developed and improved at the same time on the original basis. 2. Enhance teachers' affinity, create a democratic and harmonious atmosphere, and let students "dare to speak" in combination with teaching feedback. I found that the main reasons for the poor mathematical language expression ability of primary school students are as follows: First, teachers are more dignified, which makes students stay away from them, teachers and students are not on an equal level, and students are afraid to communicate with teachers; Teachers' leading role in the classroom is too prominent, they pursue standard answers too much, and they can't tolerate students' mistakes, so that most students remain silent for fear of making mistakes; When teaching, you can't face the whole class, only let a few "top students" answer, ignoring most students. In the long run, most students can't get exercise, and their language expression ability is naturally poor; Second, it comes from the students themselves. Some students are introverted and shy, and dare not speak in public. Third, it comes from other factors. For example, if some students make mistakes and mistakes in answering the teacher's questions, they will be ridiculed by a considerable number of students, which will make them afraid to speak. Therefore, I think that in order to make students speak confidently, we must establish a democratic and equal relationship between teachers and students and create a harmonious learning atmosphere. Start students' thinking, stimulate students' desire to say whatever they want, and let students dare to think and say. Accordingly, teachers should put down the shelf of "dignity as a teacher" inside and outside the classroom and treat students with an equal attitude. In my classroom, the teacher is no longer the embodiment and authority of knowledge, but the partner who participates in learning. Let students feel that the teacher is amiable and approachable, and at the same time feel that they are safe, harmonious and independent in getting along with their peers. In such an environment, students are eager to exchange learning experience with you, and language communication has become a sky for students to fly their hearts. It can not only cultivate students' good psychological quality, but also establish their self-confidence to express boldly in class. Teachers should try their best to adopt friendly tone and negotiation tone in classroom introduction, new knowledge exploration, feedback and evaluation, consolidation and extension, and classroom summary, so as to make the classroom atmosphere appear democratic and harmonious; In teaching, students' favorite language of animated characters is used to adjust the atmosphere, so that students' thoughts can be relaxed and their confidence from wanting to speak to daring to speak can be stimulated. 3. Teach students language expression strategies, so that students can "speak". 3. 1 In teaching, teachers should teach students mathematical language expression strategies according to different learning contents, such as numeration and algebra teaching, and mainly train students to clearly describe the sources of arithmetic, algorithms, concepts, rules and formulas; Statistics and concept teaching mainly trains students to describe the methods of collecting and sorting out data, and can express possible events in accurate mathematical language; Practice and comprehensive application mainly train students to tell their own analysis process of a problem and explain their reasoning and thinking reasonably; Space and graphics attach importance to students' oral deductive process through practical operation. In teaching, we should pay attention to teaching students the strategies of mathematical language expression and thinking in an orderly way according to the characteristics of teaching materials, organically combine the acquisition of knowledge with the development of mathematical language, promote thinking with language, and enable students to speak and speak. 3.2 Students are often guided to use concise and concise words to express the problem-solving ideas of application problems, which can be expressed according to certain logic and laws, and they can learn to speak in an orderly way over time. The process of students' methodical analysis of application problems will be expressed in coherent and complete words through repeated training. In the future, when teaching practical problems, students will still insist on oral analysis and gradually express their ideas of solving practical problems fluently, and their analytical ability and thinking ability will be improved in language expression. At the same time, it also trains students' mathematical thinking. 4. Guide students to carry out standardized language training, so that students can "be good" and say that mathematics language is a special language, which requires precise, concise and logical words. In fact, the process of training students to standardize mathematical language is also the process of training students' thinking. Therefore, in primary school mathematics teaching, we must strengthen the training of students' standardized mathematics language. Only through the training of standardized language expression can students think well and speak well. In the usual teaching process, teachers not only ask students to think with their brains and operate with their hands, but also ask students to express their thinking process in language. This kind of training is not only helpful to correct the defects of students' thinking process in time, but also helpful to find out whether the language is standardized and the words are refined in the whole expression process. This kind of training will directly affect students' learning of concepts, properties, laws and formulas in the later learning process. Only by attaching importance to the training of students' standardized mathematical language, after a long period of training, can students analyze and solve problems with mathematical ideas in their daily lives and effectively apply what they have learned. Therefore, it is very important to train students' mathematical language accurately and normatively. While standardizing students' mathematical language, teachers should pay more attention to the standardization of language, so that students can form standardized mathematical language in imitation. For primary school students, language expression ability is not perfect, but it is imitative, which requires teachers' language in class as a model and becomes the basis of standardizing students' language. Therefore, teachers' language should be accurate and exemplary, and teachers must be grammatically standardized, use appropriate words and be concise. The concept statement should be accurate, standardized and logical, and the discussion of problem-solving ideas should be well-founded and orderly. To reach this standard, primary school mathematics teachers should have the following qualities: First, they should have higher cultural knowledge. Including the depth of mastering mathematical knowledge. As the saying goes, "To give students a bowl of water, teachers should have a bucket of water." Without extensive knowledge, it is impossible to have a scientific teaching language and attract students' attention. Suhomlinski, an educator in the former Soviet Union, wrote when talking about teachers' educational literacy in the book "Suggestions for Teachers": "Only when teachers' knowledge vision is more unparalleled than the school syllabus can teachers become real experts, artists and poets in the educational process"; Second, the comprehensive quality of teachers themselves. It is not enough for a teacher to have only cultural knowledge. Teachers are a profession with strong comprehensive ability. Teachers' own qualities include: ① expressive ability; ② Teaching status; ③ Speak Mandarin well; The most important thing is to be dedicated and care about students. Only by treating students with love and warming them with love can our students be more confident and improve their language expression ability to the greatest extent.
