The new curriculum advocates student-centered classroom teaching process and students' independent inquiry learning. Efficient classroom is not only to realize efficient classroom, but also a great change in the form of education and teaching. The efficiency of classroom teaching refers to the efficient and high-quality completion of teaching tasks in a unit time (usually a class) through the guidance of teachers and students' active learning and thinking process in normal classroom teaching, thus promoting the efficient development of students. The efficiency of classroom teaching is that students have extraordinary gains, extraordinary improvements and extraordinary progress in their studies through classroom teaching activities. As the organizer of education, teachers are the most direct part of classroom reform, or the key factor to realize efficient classroom. Therefore, I think teachers should create an efficient classroom from the following aspects:

1. Teachers should handle the following changes.

1. 1 the change of teachers' roles and concepts. Teachers' role should be changed from imparting and guarding knowledge to organizing, participating and enjoying students' learning activities. In this learning process, teachers should be student-oriented, and students can understand attentively, judge with their own views and express in their own language. Classroom is no longer a place to format programs, but a stage for students' independent development. To do this, teachers should first change their ideas in time and truly realize the change of consciousness from tradition to efficient classroom.

1.2 changes in the relationship between teachers and students. The most active thing in the teaching process is the teacher-student relationship, and a good teacher-student relationship is the key to the success or failure of education. Every teacher should really walk into the students, get close to them, get to know them deeply, and treat them with equality and understanding. Only in this way can we truly build a harmonious, democratic, equal and harmonious relationship between teachers and students, and only in this way can we realize a truly harmonious and efficient education. So, how to build a harmonious relationship between teachers and students? I think we should start from the following aspects:

1.2. 1 Sincerely loving students and winning their trust are the prerequisites for establishing a friendly teacher-student relationship. Only by making students feel that you love him, will students trust you, what you say will have charisma, and your wish will come true. At the same time, students will also open their hearts to you and often confide in you, so that your education and teaching work is targeted and fruitful. To this end, I think we should pay attention to: first, we should understand and respect students, and the secret of successful education lies in respecting students; Second, we should treat all students with an objective, fair and realistic scientific attitude. Treating all students objectively is also beneficial for students to treat themselves correctly, find their own position and form a healthy psychological state. Teachers should pay attention to their own educational methods and treat students equally.

1.2.2 Make use of spare time to get to know students as much as possible, and full contact is the basis for establishing a friendly teacher-student relationship. Take the recess as the best opportunity to get to know the students, so that you can point out his mistakes or give them your own suggestions. Because students have strong self-esteem, it is easy for students to point out mistakes or make good suggestions to different students in different ways.

2. An efficient class requires adequate preparation before class.

2. 1 Keep an eye on the teaching content. "Don't fight an unprepared battle", if the classroom is to be efficient, teachers should carefully prepare lessons, carefully design teaching links, and design pre-class homework that can stimulate students' interest and arouse their enthusiasm for learning to the greatest extent according to the teaching content and students' situation. The positioning of knowledge goals should be relaxed and moderate, the unity of three-dimensional goals should be fully considered, and the three levels of good, medium and poor should also be taken into account. In addition, when preparing lessons, teachers should first make clear the key points and difficulties of each lesson, which is not comprehensive, but needs to be targeted; Understand the difficulties in students' learning process and focus on breakthroughs. In addition, teachers should prepare enough time before the next class to deal with the problems left over from the last class.

2.2 pegged to the teaching object. Preparing lessons before class must be sufficient, especially "preparing students" should be in place. Although you have designed this course wonderfully, it must meet the cognitive level of the students in your class. If not, it must be revised, because this is the key to whether we can arouse the interest of most students in this course, and students' interest in learning is an important factor to improve our classroom efficiency. For example; When the first box of the ninth lesson of Economic Life in Senior One of People's Education Edition talks about "market allocation of resources", combining with the characteristics of our students (parents are mostly suburban vegetable farmers), we introduce a new class and insert pictures of agricultural and sideline products with bad market conditions, so that students can deeply understand the hidden problems behind the phenomenon of "agricultural and sideline products can't be sold after harvest" and the contradiction between people's unlimited demand and limited resources, and draw the conclusion that society must rationally allocate limited resources. Through the process of watching, thinking and analyzing, students draw conclusions from life, return to life with conclusions, and get real life experience. With the help of multimedia teaching media, they can connect classroom knowledge learning with life situation, change the rigid and monotonous preaching form in the past, overcome the difficulties of too much content and less teaching time in ideological and political lessons, improve the efficiency of education and teaching, enhance the attraction and temptation of political lessons, and make high school students full of interest.

3. Efficient classroom needs a positive classroom state. Teachers should be good at using various teaching methods flexibly according to the specific teaching situation, discover and cultivate innovative talents, become developers of students' creative potential, carefully design methods and mobilize students' initiative in classroom learning. As the organizer, participant and collaborator of the classroom, teachers should pay attention to creating a democratic and equal classroom atmosphere, guiding students to study independently and explore cooperatively, and guiding students to actively participate, think independently, express freely and cooperate happily, so as to make students in the best state of psychological excitement and inhibition, make students full of the pleasure of seeking knowledge, stimulate students' good mood and stimulate students' theme consciousness and spirit to the maximum extent.

3. 1 Classroom should make every student move. First of all, classroom language should be full of vitality and appeal, cadence and humor. This requires the teacher's own emotional input, into the role, eyes, strong action. Secondly, the classroom should design some "baggage" similar to crosstalk performers, so that students can study in a relaxed environment. If only a certain teaching method is adopted, it will easily cause students' hearing and visual fatigue, thus distracting students' attention and reducing classroom efficiency.

The rhythm of 3.2 course in online school should change with the change of students' learning rhythm. Reasonable speaking and practicing, each class should have in-depth information feedback and adjustment to ensure the degree of achievement or generation of each class goal. In addition, the arrangement of homework should be scientific and hierarchical, and there should be a sense of the overall situation ("compulsory" or "elective" topics should be designed in homework), which is more flexible and meets the learning needs of students at different levels.

3.3 This class should be open to all students. To this end, we should also correct the understanding that cultivating students to make up for mistakes is not an after-school job, but an important part of classroom teaching. It is not difficult to find that students who make up lessons after class have no better grades than those who don't. Therefore, it is worthy of our attention to strengthen the training and make-up lessons in classroom teaching, especially the make-up lessons. Makeup, first of all, is to "cure laziness", including laziness in thought and laziness in practice. Laziness in thinking is often manifested in absentmindedness and inattention in the process of learning; Laziness in practice is manifested in slow practice, untimely completion of homework or plagiarism. In view of the above situation, effective measures should be taken to strengthen the "quick questioning" in class, increase the density of questioning, and let some slightly simple questions be used by students with poor level. What happened to Meng Yan's date with Mao Tan? Union? Are you happy to be pregnant at the weft cutting tip? Promise? X 霠靀靀靀? Curtains? Union? Eggplant, have you changed schools? Naomi Tao Di? Manganese? Σ? Dou, where's the sword? Where is Huan? What is the glory of curtains? * * * Wild Amaranth Alliance? Fear and harmony? Curtains? Paralysis? ⑾ purport baben? Letter? Collapse? [13] Easy? Hey? br & gt

4. Reconstruction of teachers' classroom structure and knowledge structure.

4. 1 Efficient classroom needs scientific learning guidance. Tao Xingzhi, a famous educator, pointed out, "I think a good teacher is not teaching, not teaching students, but teaching students to learn." Today, teachers should change teaching methods and guide students to have scientific learning methods. Traditional teaching pays attention to the interaction between teachers and students, and teachers' teaching is not easy to impress students, which leads to poor teaching effect. Interactive learning between students is similar in experience, knowledge and life scope, so students are more likely to receive education in the discussion of different opinions. Therefore, we should attach importance to interactive learning among students, and these learning methods cannot be separated from the guidance of teachers.

4.2 Classroom teaching should adhere to the "three orientations": learning orientation, practice orientation and competition orientation.

4.2. 1 learning: pay attention to students' autonomous learning, emphasize the process of students' autonomous learning, cultivate students' ability to complete learning tasks independently, and improve the overall effect of learning. In this process, the teacher is always the leader of teaching, paying attention to inspiration, making students fully move and actively participate in learning through appropriate forms, and realizing the fun brought by learning through their own practice, and finally making this kind of active learning a habit of their own.

4.2.2 Practice-oriented: students' practice is the main line in the classroom, with various forms of practice, student-student interaction and teacher-student interaction. Teachers only play the role of moderators, and the introduction of links, time control and controversial evaluation may be a way to mobilize students' subjective initiative. In this link, teachers should give students a reasonable evaluation according to the specific situation, practice strengthening classroom interaction, and achieve timely feedback on classroom teaching effect through this practice, so as to better grasp the students' mastery of the learning objectives of this class.

4.2.3 Competition-oriented: In a unit time, giving students the motivation and appropriate pressure to actively participate can introduce appropriate competition mechanisms among students (between groups) and mobilize students' learning emotions quickly and efficiently.
