First, establish a school mental health service system. The school carries out mental health services, and is equipped with a certain number of children's mental health professionals and professional psychological counseling teachers to carry out mental health services. Set up psychological consultation room, psychological reading room, psychological activity room and psychological consultation hotline in the school. Hold regular lectures on mental health and mental health care for teachers and students. Actively carry out mental health education activities and provide students with study guidance, life guidance and future career guidance. Establish and improve students' psychological files as the basis for the education and teaching of class teachers and teachers. Put mental health work into practice. Do a good job in family education for left-behind children. Family guardians should do a good job in educating children at home, fully understand the psychological status of "left-behind children", create a harmonious educational environment, strive to help children do a good job in their study and life, and contact their parents and teachers to ask them to help and assist in the management of children. What people do is entrusted by loyal people. Children's adults can safely let you take care of them, which shows that they trust you, so they should shoulder the real responsibility of guardianship and take care of their children's study and life seriously. Let them grow up happily and healthily without parents. Schools should strengthen the guidance of parents' education, and let parents know the law of teenagers' psychological development, the importance of mental health, the age characteristics of teenagers and the correct methods of educating students through parent-teacher conferences and parents' symposiums. Let parents know that teenagers are a special age stage, and students have repeated emotions and changeable behaviors. We must be psychologically prepared for this, and we must respect them and understand them. By vigorously creating a good educational environment, help them establish good interpersonal relationships. Two, strengthen and broaden the channels of communication and contact between families, schools and parents. As a school, we should not only study the present situation of left-behind children, understand their behavior psychologically, do their ideological work well, let them study with peace of mind and live happily, but also strengthen communication and contact channels with their families and parents. You can set up a telephone hotline with their families and parents, and make public the contact number of the school, so that parents can leave their contact information such as telephone and mobile phone when registering, and keep in touch with their parents. You can use the information technology courses offered by the school to let students master the basic knowledge of surfing the Internet, learn to send and receive emails and chat with QQ, and then use the school computer room to surf the Internet, so that children can contact their parents with QQ mailbox. Set up the online education exhibition platform of the school, announce the website of the school to students, and let students tell their parents about it. Set up the phone number and email address of the school principal to facilitate parents to know about the school when they work in the field. Communicate with the school. Tell parents the school email address, let them contact the school actively, give good suggestions to the school, and create a good environment for left-behind children. Let them know their children's learning situation from the principal, let them rest assured, and let the children always feel the hope and concern of their parents and schools for their growth. Let them study and live with peace of mind and understand their parents. Third, creating a good social environment has a great and subtle influence on people. A good social environment plays an important role in the growth of teenagers. The society should bear corresponding responsibilities, raise awareness and create a good social environment for young people. Let the whole people realize the future of students' motherland and create a good growth environment for children. Minors are not allowed to sell cigarettes, and gambling, Internet cafes, karaoke bars and other places of entertainment are strictly prohibited. Secondly, law enforcement departments should strengthen the supervision and supervision of entertainment places and strictly enforce the law to ensure that children are not affected by it; The third is to increase publicity and raise the awareness of the broad masses. We should consciously set up a good image in front of children. Adults are the objects that teenagers learn to imitate. Adults should keep a good image in front of their children, and don't miss and harm their lives. Through the above means, it is fully guaranteed that left-behind children can have a healthy and happy childhood like other children.
