I don't think the teacher's practice conforms to the new concept of teachers under quality education, nor is it a teacher's duty.

The formation of bad class atmosphere

In the long run, on the one hand, students will lose the consciousness of autonomous learning, on the other hand, it will affect the learning mood of other students and easily lead to the formation of bad class atmosphere.

Effective persuasion

You can talk to the students after class and convince them effectively that this behavior is wrong.

Sample demonstration

Or praise a classmate who does exercises carefully in class as an example and encourage him to return to classroom exercises.

Punishment mode

Or punish him in class, sing a song or answer exercises on the platform.

Observe students' performance more.

In future education and teaching activities, we should observe students' performance more, give priority to encouragement, and stimulate their enthusiasm for autonomous learning.
