Middle school students are in a psychological transition period. Faced with the severe pressure of further education and employment, they encounter or produce various psychological problems in study, life, interpersonal communication and self-awareness. Some problems, if not solved in time, will have a negative impact on the healthy growth of students, which will seriously lead to behavioral disorders or personality defects of students. Exploring and studying the increasingly serious mental health problems of primary and secondary school students is one of the goals of implementing quality education in schools. Pay attention to the positive guidance of the group, pay attention to the improvement of students' negative psychological state and the correction of bad behavior, and promote the healthy development of middle school students' body and mind. This paper talks about personal views on developing mental health education in chemistry teaching.

1 Get out of the misunderstanding of mental health education

1. 1 medicalization of mental health education

Mental health is an important quality that every student must have for all-round development. If mental health and mental illness are confused, mainly facing the psychological consultation of a few students, the treatment of mental illness and the counseling of psychological obstacles, and taking the treatment orientation instead of prevention and development, it will form the individualization and medicalization tendency of mental health education, while ignoring the physical and mental development of all students. Psychological counseling is only for individual students. It is only one aspect of school health education and cannot be the whole content of health education.

1.2 moral education and mental health education

Due to the lack of mental health knowledge, students' superficial behavior is "above the class" to the height of bad conduct, while ignoring the real reason behind the behavior-students' psychological needs, so they are only understood as the tasks of class teachers, political workers and teaching staff. The psychological problems are wrongly attributed to ideological and moral problems, and ideological and political education is used instead of psychological education.

1.3 discipline of mental health education

In the teaching form and content of mental health education, it is considered that mental health education is simply to set up psychological classes, or to carry out psychological counseling or psychological tests. First of all, most of the school workers in this area are monks halfway, and their professionalism is not very strong. Secondly, there are many non-intellectual contents in school mental health education, which need to be realized through personal experience such as activities, practice and training. Moreover, psychology courses can only solve some common or general problems, and it is difficult to solve individual or special problems. Often due to improper measures, the results are made public and artificially classified. It causes students to be hurt unintentionally and is more prone to mental illness.

2 infiltration of mental health education methods

2. 1 The exemplary role of teachers

Russian educator ushinski once said: "In education, everything is based on the teacher's personality, because only from the teacher's personality can the quality of education be revealed." Teachers' perfect personality affects students all the time and becomes an example for students to learn to imitate. Ideal, ambitious, conscientious and hard-working. Be honest and consciously resist social bad behavior. , reflecting a good outlook on life and values. Broad knowledge, quick thinking, decent behavior, energetic, cheerful and humorous, cheerful expression, elegant behavior, strong ability to bear setbacks, good communication and coordination skills, harmonious coexistence with others, tolerance and friendliness. The teacher's personality charm quietly touches the students' hearts, which is enough to convince them to achieve the purpose of imitation therapy. It plays a good demonstration role in the development of students' personality.

2.2 classroom infiltration

Classroom is the main activity place for students to acquire knowledge formation ability, and students spend the most time and energy in classroom. It is the main position of quality education and the main channel to cultivate good learning psychological quality of primary and secondary school students.

2.2. 1 Select the appropriate teaching content.

The psychological education imposed on students is boring and powerless, which is difficult for students to accept. The content of mental health education that should be "infiltrated" in each class should be included in the textbook of that class, which is inherent and natural. For example, by introducing some chemical processes in China, such as papermaking, gunpowder making and porcelain burning, they were invented long ago and made great contributions to world civilization. The working people in China will make exquisite bronzes in the Shang Dynasty and make ancient chemical achievements such as smelting iron and steelmaking in the Spring and Autumn Period and the Warring States Period. Cultivate students' patriotic enthusiasm. When talking about soda ash, we introduced to the students that the pioneer and founder of China's soda industry, chemist Hou, devoted himself to the ammonia-alkali process in order to break the monopoly of foreign technology, and published his own research results without reservation. Through the teaching of "Chemistry and Social Development", students can deeply understand the close relationship between chemistry and modern society. From the successful explosion of atomic bomb to the launch of artificial satellite, from the development of modern ocean to the rational utilization of resources, from the development of modern industry to the protection of human environment, from people's basic necessities of life to medical care, chemical knowledge is inseparable, so students should have a sense of social responsibility in time. At the same time, teachers should consciously use various opportunities to show students the value of learning chemistry. Make students clearly feel that learning chemistry well can cultivate scientific emotion and attitude, improve scientific practice consciousness, optimize thinking quality, cultivate students' ability to apply scientific knowledge to solve problems, and cultivate students' exploration perseverance in spite of difficulties.

2.2.2 Create a good psychological environment

Psychological environment is an invisible aspect of the teaching environment, a concrete and perceptible psychological atmosphere and situation for teachers and students in the teaching process, and a psychological emotion that resonates with teachers and students in the teaching process, that is, the overall tendency. Creating a good educational situation is conducive to stimulating students' thirst for knowledge and sense of reason, and cultivating noble sentiments and good moral quality. Teachers are the leaders of the teaching process, and they blend into the students' main body with approachable attitude, amiable face and natural and graceful teaching posture, showing equality with students. Be good at observing and understanding students, appreciate more, blame less, praise and encourage more, establish the prestige of each student, tolerate students and be kind to their mistakes. In an exam, a student with a good foundation did badly and didn't write what he should write. There was a difficult exercise for him to explain when marking the paper, and the result was very good. I went on to say, "Everything else on the test paper is well done. If this question is right, wouldn't it be more perfect? " This kind of psychological communication gave him great encouragement, improved his learning enthusiasm and maintained excellent results.

Increase emotional input, add emotional color to knowledge and information, implement emotional teaching, and use emotion with love.
