Rogers said: "The general conditions of creative activities are psychological security and psychological freedom. Only psychological safety can lead to psychological freedom and creativity in learning. " Mathematics classroom must create a relaxed and free learning atmosphere and build a harmonious classroom, which can be more conducive to students' creative learning. The democratic and equal relationship between teachers and students is the basis of creating a harmonious and active teaching atmosphere. An educator once said: "The art of teaching lies not in the ability to impart, but in inspiring, awakening and encouraging." Therefore, in classroom teaching, we should create a natural, open and innovative classroom. In teaching, I used the following methods to create a harmonious classroom and achieved good teaching results. First, bring a smile into the classroom. Many practices show that in class, teachers' expectations of students are conveyed through smiles, and students are encouraged by this love, so they love teachers and believe in their ways. Si Xia, a famous special-grade teacher, once walked into the classroom and saw dozens of students rushing into the classroom like wild horses, flushed and in a hurry. Teacher Si Xia was not in a hurry, but smiled and said, "Classmates, some children may not be ready for class. Now the teacher goes out to see who will do it first. " When Mr. Si Xia came into the classroom again, all the students sat neatly and waited for the teacher with rapt attention. I think: If Mr. Si Xia reprimands the students with a straight face, the students will be quiet, but the distracted mind will not recover at once, and it is difficult to get the expected teaching effect. Second, bring practice into the classroom. The new curriculum standard points out that observation and practice are one of the important methods to explore mathematics. Hands-on practice has a comprehensive educational function, which not only provides students with concrete, vivid and vivid perceptual materials, but also builds a relaxed and happy harmonious classroom, and cultivates students' operational skills and understands and explores natural science methods. For example, in the teaching of cone volume, in order to help students further understand the derivation process of cone volume formula, I asked students to make a hollow cylinder and a cone with equal bottom and equal height with cardboard in advance, and take it to the sand pile in class. Under the guidance of the teacher, let the students fill it with yellow sand and pour it in and out repeatedly, and gradually realize the derivation process of the cone volume formula. Through this practical operation, math class becomes relaxed and happy. Third, bring encouragement into the classroom. A relaxed and happy class is inseparable from the active participation of students, and the active participation of students is inseparable from the encouragement of teachers. Therefore, teachers should actively encourage students to think more and ask more questions, encourage students to express different opinions, allow students to be "original" and "unconventional", and encourage students to find and think about problems from different angles. In teaching, in order to encourage students to think more and ask more questions, I specially set up the "Good Students Who Love Thinking" award, and the prize is a classroom exercise book. When telling students, they will be evaluated in time with new ideas and original opinions, and will be awarded prizes after class. This not only creates a harmonious classroom atmosphere, but also greatly cultivates students' innovative spirit and ability. Fourth, bring competition into the classroom According to the psychological characteristics of primary school students, actively introduce competition mechanism in classroom teaching to fully mobilize students' learning enthusiasm. For example, in class, you can create a contest to answer questions first and then write questions, so that students who do well in writing questions can be "little teachers". Teachers can use appropriate motivational language to "see who speaks clearly", "whose method is the easiest" and "which group cooperates quickly and well" to create opportunities for students to express themselves and show their personality to the maximum extent. Practice has proved that bringing competition into the classroom will make the classroom more harmonious. V. Bringing Democracy into the Classroom Students can learn in a democratic and harmonious classroom atmosphere and feel comfortable, so as to dare to think, speak, ask, do, innovate and create. As Mr. Tao Xingzhi said, "only democracy can liberate the creativity of most people and make the creativity of most people reach its peak." In the classroom, only by giving full play to students' main role, being democratic to students and putting an end to the "centralized teaching method" can the classroom atmosphere be activated and the sparks of students' wisdom be ignited. I think it is very important to establish a harmonious classroom and bring democracy into the classroom. Only when students learn in a democratic and harmonious classroom atmosphere and feel comfortable can they dare to think, speak, ask, do, innovate and create. As Mr. Tao Xingzhi said, "only democracy can liberate the creativity of most people and make the creativity of most people reach its peak." In art class, only by giving full play to students' main role, being democratic to students, and putting an end to "centralized teaching" and "cramming" teaching methods, can the classroom atmosphere be activated and the sparks of students' innovation be ignited. For example, there are many techniques to be taught in art class, and it is easy to get bored if the teacher just demonstrates the students' learning. I think sometimes students can practice and explore by themselves-true knowledge lies in exploration; Sometimes the teacher may wish to make some mistakes on purpose during the demonstration, and students naturally understand that they should have done so long ago in comparison-facts speak louder than words; Sometimes you can play some games, such as teaching three primary colors and three primary colors, so that students can play the game of "finding friends"-moisten things silently! If teachers and students are harmonious in our class, students will be in high spirits and energetic. Then, a harmonious classroom atmosphere will be created. Six, teachers should be good at arranging teaching methods, so as to combine static and dynamic. For example, in the classroom, according to bilateral teaching activities and certain scientific procedures, teachers explain students' listening, teachers ask students' answers, teachers observe, teachers inspire students' thinking, students' hands-on teacher guidance, students' questions and answers, students discuss teachers' summaries, students' self-study teacher guidance, and students' evaluation of problem-solving teachers. So that teaching activities can be carried out rhythmically in the alternation of static and dynamic. For example, when teaching common multiples and minimum common multiples, I let students make their own teaching AIDS. In class, I ask students to spread a shop first, observe it carefully, and then talk. I found that the teacher quickly dialed the number that is both a multiple of 2 and a multiple of 3. How much can you say? Teachers summed up in time that such a number is a multiple of 2 and 3, which we call the common multiple of 2 and 3. After hands-on operation and careful observation, students have a vivid understanding of the concept of common multiple, and then under the effective guidance of teachers, abstract the concept of common multiple. Seven, teachers should strive to make the classroom ups and downs, climax after climax. Teachers' guidance on interlanguage plays a vital role in making the classroom lively and interesting. For example, after learning about A Bing's bitter experience, the teacher played two springs reflecting the moon, and the sad music made the students feel the bitterness of A Bing. But the teacher did not let the students' feelings stay here. She continued: "A Japanese said,' You should kneel down and listen to Erquan reflecting the moon'." With the overwhelming erhu sound, students' experience has risen to the national concept of honor and disgrace. Harmonious classroom is the result of the joint efforts of teachers and students, the guarantee of teachers' smooth teaching, the hotbed of students' innovation and practical ability development, and the theme we are constantly exploring! In a word, a good, relaxed and harmonious classroom is the result of the joint efforts of students and teachers, the guarantee of teachers' teaching and the hotbed of students' innovation and practical ability development. In mathematics teaching, we should actively create a harmonious classroom, let students be good at thinking and learning, improve their quality in an all-round way, and cultivate their innovative spirit and practical ability. Harmonious classroom teaching can promote students' intellectual development, knowledge mastery and ability improvement. In harmonious classroom teaching, students' thinking is in a positive state, with high emotions and active thinking. Harmonious classroom is exactly what teachers pursue.
