I think these underachievers have the following characteristics: First, their learning objectives are unclear and their learning attitudes are not correct. Second, high self-esteem. Once the criticism of the subject and the class teacher is not in place, their psychology, words and deeds will go to the opposite of the teacher. Third, a strong sense of inferiority. Underachievers are often criticized and educated by teachers because of their poor study and poor performance in all aspects; There are also sarcasm among classmates, which makes them feel inferior and then give up on themselves. Fourth, the rebellious mentality is strong. They deeply feel that others look down on them, and their words and deeds cannot be unified in their daily moral behavior. They are dissatisfied with the teacher's criticism of their words and deeds. In the next class, he will talk or make small moves, which will affect the teacher's class and the attendance of other students. In view of the above characteristics of underachievers, I think we should do a good job in the following aspects: First, love and patience are the basis for transforming underachievers. No matter what kind of students and their behavior, the head teacher or teacher should face them with love and patience, accept them, pay more attention to the special group of the class-underachievers, and let them feel that they are equal to other students in the eyes of the head teacher and teacher. Second, equal dialogue between teachers and students is the main way to transform underachievers. In view of the frequent violation of discipline by underachievers, it is very important to use the equal exchange and dialogue between teachers and students of "moving with emotion and understanding with reason". Through dialogue, let them realize that their behavior is not standardized and get an understanding from their thoughts. Adhere to positive induction, convince people by reasoning, not simple and rude, and oppress people by force. You can also use collective public opinion to give these underachievers clear rewards and punishments. Third, respecting and trusting underachievers is the main method to transform underachievers. Self-esteem is one of the important signs of people's self-awareness, which is manifested in self-esteem for individuals and requires others to respect their rights and personality.
