How to Cultivate Primary School Students' Speaking Ability in Mathematics Class
Piaget, a famous psychologist, pointed out that language is an accelerator of intellectual development. Language is the coat and tool of thinking, which can generalize and standardize thinking. People can abstract and summarize things with the help of language, and in turn standardize people's language with the help of thinking. In classroom teaching activities, students' oral expression is an important source for teachers to obtain teaching feedback information, and it is also the main basis for teachers to adjust teaching strategies. Cultivating students' oral expression ability from an early age will have a great influence on their life. In primary school mathematics teaching, in order to promote the development of students' thinking, cultivate students' expressive ability, give timely information feedback, correct mistakes in time, and help students understand and master knowledge, we should create conditions for students to talk more, strengthen students' speaking training, stimulate students' desire to speak more, dare to speak, want to speak and know how to speak, and attach importance to the cultivation of "oral expression ability". In classroom teaching, teachers should let students "talk" more. More "talking" is to give students the opportunity to express their thoughts, opinions and opinions in class and help students improve their oral expression ability. Then, how to strengthen students' oral training in class in a planned way and strengthen students' "cultivation of oral expression ability"? To improve students' mathematical expression ability in teaching, we can follow the following strategies: strengthening the explanation of mathematical language; Give full play to the exemplary role of teachers; Attach importance to the transformation between different forms of mathematical language; Provide opportunities for mathematical expression; Help students overcome psychological barriers. The specific method is as follows: (1). Students can train to express their ideas orally by looking at pictures and talking. In teaching, students should be taught to look at the picture in an all-round way, see clearly what is painted on it, and let students learn to say a few words according to different meanings. In this way, students can cultivate their mathematical oral expression ability in the process of looking at pictures and explaining their meanings. (2) It is difficult for teachers to demonstrate that students are young and monologue language is difficult. They often learn to express themselves by imitating other people's speeches. At this time, the exemplary role of teachers is particularly important. In teaching, teachers' language is an important factor to stimulate students' imagination and promote language development. Teachers should try their best to tell mathematical concepts and calculation methods in correct, clear and vivid language. Teachers demonstrate speaking, students imitate speaking, accept these signals through imitated media, internalize them, and gradually become their own language expression. For example, when teaching 9+2, the teacher should explain the calculation process by rounding up ten (see large numbers, divide decimals, and make up ten), and then let the students see the physics demonstration diagram and formula. According to the appearance, students can imitate under the premise of understanding and learn to say the calculation process. Formula diagram: 9+2= 1 1 Student expression: Think of 1 when you see 9. Divide 2 by 1 and 1, 9 and 1 composition 10, and add 1 to get 1 1. When teaching, you can also ask students with strong oral expression skills to demonstrate and lead everyone to tell. For example, after studying 9+ for several hours, when teaching 8+ for several hours, students can be encouraged to describe their thinking process in the calculation process, which can fully mobilize their enthusiasm and make them strive to become "primary school teachers". Please try to talk about it. After the relatively weak students can fully express themselves, please talk to each other at the same table and evaluate each other. Individual students can't speak at all, but the deskmate can help them speak, and finally let the whole class speak. The teacher's demonstration and the student's demonstration lead the way for everyone's speech, and the students set an example to improve the oral expression level of the whole class. (3) Oral Practice Conduct oral practice 5 minutes before each math class, and practice immediately after answering the questions. Students can exercise their oral expression ability in the process of answering the questions. This link can not only exercise their oral expression ability, but also cultivate their concentration, killing two birds with one stone. (4) Summary report summary is an important part of classroom teaching. Summarization can improve students' comprehensive generalization ability and clearly recall the main points of this lesson. At first, students' expressive ability is limited, but as long as they are guided correctly, they can sum up correctly. For example, at the end of the class, you can ask, "What have you gained in this class?" After sorting out the memories, the students raised their hands to speak one after another, and even the students who are usually quiet and some underachievers are very active. Although some students are concise, they have grasped the key points of this lesson, which not only deepened their understanding of knowledge, but also developed their learning ability. Moreover, regular and purposeful classroom summary can improve students' logical thinking ability such as analysis, generalization and classification, and achieve the goal of intelligent progress and comprehensive education. (5) Provide opportunities to pay close attention to the intensive training of students' oral English in math class. For example, in oral arithmetic teaching, students are not only required to say the numbers of oral arithmetic, but also trained to "say" their own ideas and oral arithmetic process; When teaching calculation problems, students are required not only to calculate, but also to tell the order of operation; When teaching simple calculation problems, students are required to tell the reasons for simple calculation, that is, to tell what algorithm or nature is used to simplify calculation; When judging problems in teaching, ask students to tell the reasons for the mistakes; When solving problems in teaching, students are not only required to answer, but also "talk" about the process of mathematics and answering. In a word, strengthening the training of "oral expression ability" in primary school mathematics classroom teaching can enliven the classroom atmosphere, cultivate students' good thinking and expression habits and improve their oral ability. More importantly, in the process of "speaking", students can learn mathematics knowledge and enhance their initial logical thinking ability. Strengthening the cultivation of "oral expression ability" in mathematics classroom plays an important role in improving students' quality.
