This problem is reflected in the fact that teachers are only trying to complete the task of teaching materials in classroom teaching, rather than helping students complete their learning tasks. Its performance is that teachers occupy most of the classroom time, leading to teacher-centered teaching. Teachers' speeches and activities account for more than half of the classroom, and it is not uncommon to write on the blackboard for the sake of writing on the blackboard and demonstrate for the sake of demonstration.

Reflected in the teacher's attitude is blunt and impatient, teaching for the sake of teaching. I have forgotten the educational effect of my behavior and attitude on students since class. I don't know that teachers' influence on students' behavior norms is much more important than the cultural knowledge they teach. In teaching, it is obvious that the students are helping the teacher to complete the teaching task, not the teacher is helping the students to complete the learning task.

2, the method is not appropriate

The reform of teaching methods is the main content of teaching reform for many years. Although great achievements have been made in this respect, teaching practice is still centered on teaching materials and teachers, rather than students. Reflected in the classroom teaching mode, it is in research teaching rather than research. Learning needs situation, and situation is an internalized process to a great extent. However, the present classroom teaching obviously highlights its externalization function. Originally, students' thinking and language are sometimes not completely synchronized. When they think about it, they may not be able to say yes, but whether they can say yes or not does not mean that they can say yes.

3. Renew the concept of education and make clear the educational objectives.

Educational concept is the ideology in teachers' teaching, which determines teachers' educational behavior. Now the speed of knowledge updating is accelerating, and people can't master all the knowledge. The main task of learning is to learn to adapt to society, to adapt to the times, to learn lifelong learning and to learn to survive. Every math teacher should understand his task and responsibility.

4. Improve teachers' quality and reform teaching methods.

The quality of teachers directly determines the success or failure of curriculum reform. Teachers' quality includes many aspects, among which teachers' ideological quality and professional quality are closely related to classroom teaching reform. Due to the particularity of the nature of teachers' work, teachers must have high ideological quality. Teachers' professional ethics determines teachers' work performance in a certain sense. Although the quantification of teacher assessment is advocated, it is sometimes difficult to quantify the achievements of teachers' work.
