(A) from the concept, to further improve the professional quality.

To build an "efficient classroom", we should pay attention to the guidance and leading role of teachers. Teachers should have advanced and practical ideas, establish the concept of equality and democracy, stop singing solo, be the judge of knowledge and the master of the classroom. Instead, we should put down our airs, pay attention to students, strive to be their study friends, give them more appreciation, encouragement, tolerance and understanding in class, and become excellent classroom teaching organizers, instructors and collaborators. Pay attention to simple and efficient teaching design, reasonably attractive situation creation, flexible and practical teaching methods, and avoid lively but ineffective flow.

(B) the cultivation of students' autonomy

"Efficient classroom" is a student-centered classroom. Teachers should give full play to their guiding role, boldly let go and return the initiative of learning to students.

Create a reasonable situation and be good at inspiring and questioning. And make this situation have distinct characteristics of the times, emotions, life and participation. We should throw stones at the waves, improve the situation, stimulate students' cognitive desire, trigger students' cognitive conflicts, awaken students' questioning thinking, teach students to question, make students willing to find problems, ask questions, be brave in exploration, and cultivate students' ability to analyze and solve problems.

Grasp the social hot spots, focus issues and other breakthrough points, let students ask questions, design and solve problems themselves, and cultivate and improve the ability of knowledge generation. To give full play to the role of group cooperation, we must first divide groups reasonably. The division of group members should consider the gender collocation, the complementarity of personality characteristics, the collocation of various specialties, the hierarchy of academic performance and the balance of organizational ability, and design the best group. Second, do a good job in group training: determine the responsibilities of group members, so that they can clearly define their tasks and perform their duties. At the same time, it emphasizes strengthening cooperation and establishing corresponding reward and punishment system for supervision and encouragement.

(3) Use love to influence all children.

The true meaning of education is a word "love". In the teaching process, under normal circumstances, teachers have low expectations of poor students. In fact, think about it, it is the so-called "poor students" who affect our teaching results. Many teachers think that poor students are poor in everything! Even lost hope for them. Calm down and think about it. Why are poor students poor? Why is it against discipline? There is a saying that "being idle is also idle", so it is necessary for us to stick to three points: don't abandon, don't abandon, don't abandon. Then we should look at them in the right way. We need to pay more attention to them, and enforce "hierarchical teaching" in class, hierarchical design for classroom practice and hierarchical design for homework after class. For example, the top students do five questions, the poor students do three questions, and the top students are tall, so the poor students can do exercises to consolidate the double basics. After a long time, it will become a habit, so that top students can eat enough and poor students can improve. At the same time, we should also stimulate their interest in learning and cultivate their self-confidence and sense of success. In a word, "preventing mistakes" is better than "making up mistakes". In order to improve the efficiency of classroom teaching, we should "nip in the bud".
