Due to the lack of parental care and poor communication channels, it is difficult for left-behind children to express their true thoughts to the outside world, and it is easy to form autistic psychology; In addition, in the process of communication with peers, left-behind children can't get timely guidance of their own ideas because of the explicit and implicit reality gap, and are prone to serious inferiority and frustration. The lack of family care, children grow up in a lack of warm environment, so that children do not know how to enjoy love and care for others; Without psychological support, children can't get the encouragement and affirmation they deserve, which leads to their lack of self-confidence in life and study.

Good interpersonal relationships can help lonely and indifferent students learn to care about others and help each other in the process of interacting with classmates. As the saying goes, "reciprocity", interpersonal communication is reciprocal. Only when you associate with others will others be willing to associate with you. Educate them to start with the simplest initiative to say hello to their classmates, and take the initiative to chat with them every day to form a habit so that they can gradually get rid of loneliness. At the same time, consciously hold more cultural and sports activities, such as Teacher's Day and "Six".

First, arrange cultural performances on Mid-Autumn Festival and other festivals, and hold sports meetings in spring and winter to mobilize them to participate. In the process of participation, we will unite and cooperate with other students and work together to win glory for the collective.

Helping left-behind children to build self-confidence in life and study is the key to overcome their inferiority complex and make them believe in their abilities in the face of various difficulties and setbacks. We should be good at discovering the bright spots of these children and give them timely praise. The famous educator Suhomlinski said: "There are no talented people in the world. The problem is that educators should discover the talents, interests, hobbies and specialties of each student and provide sufficient conditions and correct guidance for their performance and development. " In fact, every gifted child will be proud of it and build self-esteem and self-confidence. Psychologist William.

James said: "The deepest principle of human nature is to beg for the concern of others." Generally speaking, left-behind children have strong self-care ability. The class teacher can intelligently set up positions such as "Assistant of Labor Committee" and "Representative of Labor Technology Class" in the class cadre distribution, and encourage left-behind children to actively participate in the competition for these positions. Teachers should carefully observe the left-behind children, try to find their advantages, make rational use of their advantages, and let them participate in the collective management of the class, so as to establish their confidence in life and study.

In view of the situation that left-behind children are weak-willed and not good at overcoming difficulties, various types of themed class meetings, speeches and other educational activities can be carried out to make students realize that the gap between classmates is objective and setbacks often occur, and they should face up to the setbacks and difficulties they face; At the same time, organize students to understand the stories of celebrities and great men, and let them talk about their own views and experiences, so as to improve their understanding of life. In addition, teachers should make more efforts to cultivate children's consciousness, decisiveness, self-control and persistence, so as to exercise their will.
