The great role of "interest" in educational practice has been affirmed by many educators at all times and in all countries. An educator described how teachers stimulate and cultivate students' interest: "The art of teaching lies not in imparting skills, but in inspiring, awakening and inspiring." Children are in hyperactivity stage, and their attention is often unable to concentrate. Without stable interests, their development is impossible. Therefore, to stimulate students' desire to speak, we must cultivate their interest. Efforts should be made to create an atmosphere of "speaking" for students.
Professor Ye Lan once suggested that the classroom should be full of vitality, and teachers should not suppress students with a serious attitude, so that students can always be bound under the eyes of teachers and lead students to achieve teaching goals, which greatly suppressed students' thoughts and emotions. In teaching, teachers should be willing to crouch down and get along with students on an equal footing, create a relaxed, democratic and harmonious classroom atmosphere, let students feel "psychological security" and "psychological freedom", participate in learning with a cheerful, positive and excited attitude, and fully express their opinions through activities such as observation, operation, speculation, communication and reflection.
Second, teach methods, state opinions and guide students to "speak" skills.
Speech is also an art, which requires the speaker to show his thinking activities to the audience accurately and clearly through mathematical language, without ambiguity or ambiguity. Therefore, in the process of cultivating students' speaking ability, it is particularly important to teach students the methods of speaking.
The so-called statement of ideas is the process of thinking. In class, every student should have the opportunity to express his ideas, such as whispering alone, practicing speaking at the same table, talking to each other in groups of four, and talking to the whole class. Learn the way of thinking by speaking. Through this kind of training, students will get used to stating ideas and solving problems by themselves. In the teaching of practical problems, students are required to make clear the meaning of the problem in mathematical language, express the quantitative relationship and the thinking of solving problems, and dictate the formula basis, solving steps and methods according to the operational meaning. For example, when I was teaching calculation application problems, the topic I used was "The supermarket sells 5 boxes of thermos pots a week, each box is 12, and each thermos pot sells 45 yuan. How much did it cost? " For example, train students to think like this according to the conditions: According to the 45 yuan calculation of each box 12 thermos, can we find out how much each box costs? Sell another 5 cases to * * *, how much is it? Starting with the question, we can think like this: First, how many thermos pots are there in five boxes? How much did the other * * * sell? The result is obtained from these two conditions. Students are often guided to dictate the ideas and steps of solving problems in simple and clear sentences like this, and they can learn to speak in an orderly way over time.
Third, refine the language, step by step, and improve the organization of "speaking"
Whether the mathematical language is complete, accurate, concise and organized depends to a great extent on the focus of our training in different classes. Therefore, in the process of classroom teaching, we should not only pay attention to the cultivation of students' oral English, but also focus on different classes.
After guiding students to observe, analyze, reason and judge in teaching, students are required to answer questions concisely and accurately in mathematical terms. Inspire students to sum up definitions, laws or formulas in their own words, so that perceptual knowledge can be upgraded to rational knowledge. For example, when I teach triangle area calculation, I first teach students how to spell, and then let them operate. After the operation, ask the students to answer the following questions in turn: 1, how do two triangles combine into a parallelogram? 2. What is the relationship between the area of parallelogram and triangle? 3. What is the relationship between the base and height of parallelogram and the base and height of triangle? 4. How to calculate the area of parallelogram? What about the area of this triangle? Through continuous and complete language, the calculation formula of triangle area is deduced, which makes students understand the process of knowledge formation thoroughly and remember it firmly. In the process of organizing language, students' thinking is organized and accurate.
Fourth, learn to reflect and cultivate the ability to "speak"
The most important thing for students to learn is to learn to learn, and the most effective knowledge is self-control knowledge, that is, reflective wisdom. Reflection refers to the process of people thinking about their own behaviors and thoughts, and it is a re-understanding of cognitive activities. The new curriculum standard puts forward the goal of cultivating students' "initial evaluation and reflection consciousness" from the perspective of comprehensive education.
Strengthen classroom reflective teaching activities. Once students make mistakes in practice, they should not only correct them, but also seriously reflect on the causes of the mistakes and tell them in class. Over time, students have developed a good habit of being responsible for their own wrong questions, accumulating wrong questions independently, analyzing the reasons of wrong questions independently, and improving their academic ability through reflection.
The cultivation of mathematical language expression ability is not achieved overnight. Only through long-term and planned training can they dare to think and speak, be willing to think and speak, and be able to speak and speak in class, so as to cultivate their thinking ability and language expression ability and make classroom teaching solid and effective.
