The so-called "effective teaching" is the modern teaching concept of improving teachers' work efficiency and strengthening process evaluation and target management. It refers to a new educational idea that teachers follow the teaching rules and principles, invest as little time, energy and material resources as possible, and achieve as many teaching effects as possible, so as to achieve the predetermined teaching goals and meet the educational value needs of society and individuals. It emphasizes three elements. First, it is effective, that is, students have learned the prescribed teaching content and learned it. In other words, when evaluating a class, we should focus on the students, not the teachers. We can't just look at how extensive and profound the teacher's explanation is, how detailed the teacher's understanding of the teaching materials is, and how novel and unique the teaching methods are, but how much the students have gained. This is a fundamental change in the concept and evaluation criteria of teaching evaluation since the implementation of the new curriculum reform. In the past, some teachers always focused on "talking" in class, boasting and usurping the role of the host, and some open classes or demonstration classes always had fraudulent renovations, all because of the biased teaching evaluation concept and standards. We say that any teaching that ignores students' actual gains, whether in the context of curriculum reform or in normal teaching, no matter how "novel" or "innovative" in style, is a failure. Achievement is the most accurate quantitative yardstick to measure the effect. In recent years, the Education Bureau has resisted the pressure of public opinion from all sides, repeatedly emphasizing "openness and clarity" and "clarity every day", and has never relaxed. That's the reason. Because of high grades, it is the last word. To run a satisfactory education for the people, we must first improve the quality of education. Only when students get high marks can the people be satisfied, our work can win the concern of the party and the government and the support of all walks of life, and we can also create a good development space for our work. Therefore, I hope that all the principals present here can confidently and confidently put forward the rigid requirement of "improving students' academic performance and not letting any child fall behind in academic performance as far as possible", calm down and thoroughly study the relationship between effective teaching and improving students' academic performance.

The second is efficiency, that is, most or all students have learned, and they have all learned. "For the development of all students" is the core concept advocated by the new curriculum. For a long time, due to the problems of education system and entrance examination orientation, some schools only pay attention to top students and high scores in teaching, which leads to the neglect of teaching efficiency. To be precise, it is the neglect of those poor students. These people have become "forgotten corners", and they will certainly meet, but they will not. Anyway, they can't get the point and get into the famous brand. We emphasize that the purpose of effective teaching is to prevent students from falling behind. The purpose is to effectively transform students with learning difficulties, critical students and lame students, so as to achieve "gifted students are better, ordinary students are stronger, and backward students catch up". On the operational level, we should not simply use the average score or ranking method to measure the future performance of a class or a student, but should pay attention to weighing the degree of its promotion and evaluating its ability of sustainable development. Only in this way can our teachers truly face the whole and give consideration to the upper, middle and lower levels, so as to achieve efficiency at all levels.

Finally, it is beneficial to use as little time as possible, as little investment as possible and as little burden as possible, so that students can achieve the above effects and efficiency. This point, it should be said, has been repeatedly called for a thorough solution from the central government to the local government, but it has not been solved so far. There are many reasons for the heavy burden on students. From the teaching level, it is mainly because some teachers don't study textbooks, analyze the learning situation, choose teaching methods, and do not study exercises and test questions in depth and in place, which leads to ineffective or inefficient teaching. In this case, in order to improve students' academic performance, they have to fight for time and questions. These high consumption and low efficiency practices must be seriously solved in the in-depth implementation of effective teaching.
