Liu Jian, the first vocational secondary school in hua county, Henan Province, established mental health education, which is a preventive education that takes various methods and measures to mobilize all internal and external positive factors, maintain individual mental health, cultivate good psychological quality and promote the improvement of their overall quality. In the teaching process of secondary vocational schools, I found that many students are psychologically abnormal, and students' learning-weariness obstacles and interpersonal problems are quite prominent. Vocational school students with psychological problems account for more than 20% of the total, which are characterized by personality deviation, weariness of learning, online seclusion, puppy love and serious rebellious psychology. Their hearts are full of contradictions and puzzles, so it is very necessary and important to carry out mental health education for secondary vocational school students. There are many reasons for students' mental health problems in secondary vocational schools, but the main ones are social influence, family environment and teachers' educational methods. It reflects many contradictions in society, family and school education. Only by understanding the causes of students' problems can we consciously avoid them in education and teaching. According to the causes of mental health problems of secondary vocational school students, I think we should improve and strengthen the mental health education of secondary vocational school students from the following aspects: 1. Create an environment conducive to the mental health development of secondary vocational school students-create a beautiful and civilized school environment. School is students' second home, and students unconsciously accept the education and influence of the school. Therefore, an elegant, clean, civilized and comfortable school environment can give students a good psychological edification of "calming down". The unique cultural atmosphere formed by the design and construction of the humanistic environment of the school class makes students feel the powerful and unique charm of the big family, and produces the feeling and pride of "I am proud of the school class" from the heart. Second, strengthen teachers' learning and improve their psychological quality. To carry out mental health education for students, we must first improve the psychological quality of teachers. The increasingly busy modern life has brought many psychological changes to people. Faced with fierce employment competition and tangible and intangible pressure from all aspects of society, some teachers have psychological conflicts and a sense of oppression. The unhealthy psychological state of teachers will inevitably lead to inappropriate educational behavior and have a bad influence on students. Secondly, teachers should pay attention to their own mental health. Teachers' professional characteristics require teachers to have strong self-regulation ability. Teachers should use scientific knowledge to adjust their mentality, so that they are always in a positive, optimistic, peaceful, stable and healthy psychological state, and devote themselves to education and teaching with vigorous energy, rich emotions and healthy emotions. Finally, teachers should be given extensive psychological knowledge training. Schools should take mental health education as an important part of teachers' continuing education, so that every teacher can master the basic knowledge of mental health, thus correctly guiding students and avoiding mistakes in the process of education and teaching. It is very important to cultivate a team of teachers who are mentally healthy, know psychological professional knowledge, master psychological counseling skills and psychological training methods. At the same time, reform the school as a whole, correct educational ideas, reform education and teaching methods, harmonize the relationship between teachers and students, and create a happy learning and living environment for students. In fact, the teaching of each subject itself contains the content of psychological education. As long as the guidance of psychological education is added in preparing lessons, the teaching content can be deepened, such as aesthetic education for students in the teaching of program design, graphic design and animation design, and emotional education for students in Chinese teaching. Physical education class can arrange frustration education to increase students' ability to resist setbacks and exercise their willpower. The best way is to add the subsection goal of psychological education to the teaching purpose of each subject, so as to change the education mode from knowledge education to quality education and psychological education. 4. Offering relevant mental health courses in secondary vocational schools to educate students in secondary vocational schools. Mental health education courses should be knowledgeable, interesting, participatory and operational, so as to apply what they have learned, really improve students' ability to resist setbacks and self-adjust, and reduce psychological obstacles and other psychological problems. Make every student reach mental health standards such as normal intelligence, emotional health, sound will, coordinated behavior and interpersonal adaptation, and comprehensively improve students' psychological quality. 1. Guide students to vent their bad emotions reasonably. Because secondary vocational school students are immature and emotionally unstable, if they can't vent their frustrations in time, it may cause adverse consequences. According to this feature, we should create reasonable channels for them to vent and prevent improper venting. 2. Desalinate passive education and cultivate independent ability. Secondary vocational school students come from complex sources, most of them are students with bad behavior, and their autonomy in study and life is poor. Therefore, we should pay special attention to helping them form their autonomous ability, pay attention to guiding, encouraging and discovering their bright spots, and help them find their own solutions on the basis of analyzing problems. 3. Pay attention to education and cultivate students' good study, life and behavior habits. The self-rationality and self-control of secondary vocational school students are not mature enough, and many psychological obstacles are related to bad behavior habits. Therefore, when regulating them, we should pay special attention to the cultivation of behavior habits, standardize their behavior with strict discipline system, and help them correct their bad behavior step by step and form good habits. V. Strengthening guidance and help to parents At present, most parents of students lack knowledge of pedagogy and psychology. China Youth Daily reported: "95% parents have never read books on psychology, and 72% parents have never read books on education." They don't know how to educate their children more scientifically. Therefore, the school should 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. In addition, we should pay special attention to students from "problem families" and help them overcome their psychological problems caused by the bad influence of their families. Six, the establishment of psychological counseling room in the school, equipped with professional psychological counselors, timely counseling students' psychological problems, to prevent more serious problems. "Planting trees for ten years, educating people for a hundred years." Mental health education for students in secondary vocational schools is a long-term systematic project. Improving and strengthening students' mental health education requires the joint efforts of schools, families and society to create a good growth environment for students. At present, the education department and secondary vocational schools have begun to make a lot of efforts for students' mental health education, and have also received some results.
