First of all, only by understanding and respecting students can we communicate with them effectively. In this way, we can ask questions and communicate with students on the basis of understanding their original knowledge. Results The students were very active in learning, thinking positively and speaking enthusiastically, and the classroom atmosphere was active, which achieved good results. Second, create a good situation for effective communication with students. Creating a good situation is conducive to students' positive thinking and stimulating strong interest in learning. More importantly, they can communicate effectively with students on specific issues, cooperate in an all-round way, discuss issues from different angles, let students use their brains, speak actively, discuss and find problems in a targeted manner, and express their views and opinions on problems, so as to solve problems well and effectively. For example, let's learn the section "Trapezoidal midline" and let the students do it by themselves. First draw a △ABE, and then draw the midline MN of △ABE. Communicate with the students as follows. Please try it! 1. Let the intersection point n be a straight line DC intersecting with point C (but not parallel to AB) and a ray AK intersecting with point D. Third, according to the specific situation, timely and effective communication with students is communication, communication is good cooperation with students, mutual discussion between teachers and students, and * * * communication with different views and opinions on the problem, so as to find out the methods and strategies to solve the problem. It is worth noting that we can't communicate with students all the time. It is necessary to give students a broad and free development space and let them communicate in time. 1. Communicate effectively with students when they encounter difficulties in their studies. The classified queries of periodical articles are all in the periodical database. When some students feel at a loss when solving problems or answering questions, teachers can communicate with them directly. First of all, we should mobilize their enthusiasm for learning, encourage them to think positively, and encourage them to say, "You can do it, try again in another way, and so on." At the same time, on the basis of students' communication, discussion and cooperation, teachers give explanations and guidance, and give students methods and ideas to solve problems. 2. When students are hesitant, communicate effectively. Students' study is not smooth sailing, especially in mathematics. In the process of learning, sometimes you will encounter such a situation. Students do not have a firm grasp of the mathematical concepts, theorems and formulas they have learned, and their understanding is not thorough, and some even have a little knowledge. I feel powerless when I encounter math examples and exercises, and the answers to the questions are ambiguous, so I dare not say if I want to. In this case, teachers should communicate with them in time, encourage students to speak actively, boldly express their views and opinions, and say what they want to say, even if they are wrong views and conclusions. Students speak freely, and students at different levels express their opinions, which not only promotes democracy, but also mobilizes students' enthusiasm for learning mathematics. Why not? 3. Communicate effectively with students in the process of exploring problems. In the process of students' learning mathematics, especially when students discuss problems, teachers must always pay attention to every student, especially those who are slow to respond and have poor thinking ability. According to students' different levels and situations, different methods and measures are adopted to communicate effectively with them. 4. Communicate effectively when students are most keen on discussing problems. The learning process of mathematics is a difficult and complicated process, which requires every student to make great efforts, especially when the enthusiasm of students to discuss problems is the highest. Teachers should communicate with them in time, help them solve problems as soon as possible, and let them solve problems quickly. Fourthly, communicate effectively with students in inspiring and inspiring teaching language. Mathematical language should be scientific, accurate, standardized and concise. For example, when explaining the concept of "parallelogram", we say: "Two groups of parallelograms with parallel opposite sides are parallelograms." But we can't say, "A quadrilateral with parallel sides is a parallelogram." Without the word "two groups", this sentence is not accurate and standardized, and students understand confusion. I didn't know that "two groups of opposite sides" and "one group of opposite sides" were parallel respectively. This has increased the study burden of students, and we must abandon it. 3. Communicate with students in inspiring, inspiring and infectious language. In class, the author often uses words such as "Take your time, try again, you can do it, you are fine, think again". These languages encourage students to think positively and speak boldly, thus stimulating their enthusiasm for learning. Effective communication and exchange should be geared to all students and promote their all-round development. One of the new curriculum ideas is to emphasize the all-round improvement of students' quality, face all students and promote the development of every student. In junior high school mathematics classroom teaching, we should face all students, communicate with them in time, leave simple questions to students with poor foundation, let middle school students think more complicated questions, and leave certain difficulties to top students to explore and solve, so as to teach students in accordance with their aptitude. Let every student at different levels get balanced development, have the opportunity to get education and equal opportunities, and let them experience the joy of success. Practice has proved that it is necessary to strengthen effective communication with students in junior high school mathematics classroom teaching, which has positive practical significance for fully developing democracy and mobilizing students' initiative and enthusiasm in learning.
