Teachers' good work will promote students' mental health.

Good teachers (moral will, moral behavior, moral emotion) will promote students' mental health.

Mental health means that all aspects and activities of psychology are in a good or normal state. The ideal state of mental health is to maintain a state of complete personality, normal intelligence, correct cognition, appropriate mood, reasonable will, positive attitude, appropriate behavior and good adaptation.

Teachers with sound psychology can always maintain a warm, optimistic, positive and uplifting attitude in their teaching activities. They keep learning, updating, making progress and creating. According to the characteristics of students' physiological, psychological and social development, they can creatively use language, analyze teaching materials, choose teaching methods, design teaching links and create classroom atmosphere.

This positive emotion of teachers' involvement in teaching can help students maintain a happy learning mood and promote the communication between teachers and students, thus achieving good teaching results.

Therefore, such teachers are deeply loved by students. In teaching, they are willing to learn, have strong curiosity and interest, actively interact with the environment, and strive to overcome all kinds of difficulties encountered in the learning process and innovate to achieve ideal learning results.

As the saying goes, "Learn from your teacher and believe in it." We find such a common phenomenon that students like a teacher and generally like the subjects taught by the teacher, and the learning effect is better. Primary and secondary school students' weariness and fear of learning are related to teachers in some cases.

Improper handling by teachers will do harm to students;

Some teachers ignore the individual differences of students, use excessive language, treat students with poor grades coldly, and do things unfairly, resulting in psychological damage to some students. This will inevitably affect students' interest in learning, and it will also inevitably affect students' knowledge-seeking effect.
