With the progress of social science and technology, people's living standards are improving day by day, and their cultural quality is also gradually improving, thus making their children develop better: their bodies develop early, and 60% students enter puberty around the sixth grade of primary school; Social experience is broader and deeper than that of students in the past (or children now know several times or ten times more than their peers ten years ago). These "developments" not only have their functions, but also have their disadvantages. From the investigation of several primary schools, it is found that: first, some students know little or even "ignorance" about adolescent knowledge, which leads to students' inability to carry out necessary and timely health care, and even great psychological "fluctuation", resulting in various unfavorable factors such as great ideological pressure, depression and sharp decline in grades. Secondly, puppy love also exists among primary school students, especially the sixth grade students, and most students know nothing about the connotation or concept of puppy love, so this phenomenon can also be called "naivety", but if this phenomenon is not handled properly or in time, the consequences are often difficult to control.

Adolescence (commonly known as transitional age) refers to the transitional stage from childhood to maturity. Its biological basis is the gradual maturity of sex. This period is a critical moment that determines a person's physical, physiological, psychological, personality and intellectual development throughout his life. It needs not only physical maturity, but also knowledge, skills and strong psychological endurance to perform various social functions and assume social responsibilities. Students in adolescence often have various contradictory emotional experiences: joy and trouble, cheerfulness and silence, socialization and loneliness, boldness and timidity. They gradually know themselves, are interested in everything around them, are willing to evaluate and intervene in the ranks of adults, and consciously want to get rid of their dependence on their parents, resulting in the phenomenon of "psychological weaning". This sharp weaning phenomenon brings anxiety to teenagers, causing mood swings and confusion. Because of the sexual instinct, they gradually turned their attention to their own interior. If we don't grasp the essence of this change in time, teenagers will fall into anxiety, confusion, anxiety and indifference, and will adopt a "negative" attitude not only to the outside world but also to themselves. Psychologists call adolescence a stormy period. People's physiological and psychological changes vary widely, and the development trend is jumping, which is a "dangerous period" of life. Therefore, we should pay attention to the subtle emotional changes of students and attach importance to the adolescent mental health education of students.

First, students' mental health standards

The purpose of mental health education activities is to eliminate all kinds of factors that are not conducive to the physical and mental development of teenagers, and to cultivate their good adaptability to social life and good personality and psychological quality. The standard of mental health is:

1, can correctly understand the surrounding world and has good adaptability.

2. Rich, positive and stable emotions can respond well to others' emotions.

3. Strong self-control, able to withstand setbacks and overcome various difficulties at home and abroad.

4, have a stable interest and aesthetic knowledge, social needs.

5. Be confident, be good at getting along with others, be ready to help others, and treat life with a positive attitude.

Second, the reasons for students' psychological barriers and bad moral character.

1, the influence of poor family education and bad environment. As an only child, parents have unprincipled love and protection. In life, eroded by the decadent lifestyle, we have everything we want and lack strict management system. In learning, I have high hopes for it. Maybe I take a rude way to suppress education. The strong difference between study and life requirements can easily lead to psychological barriers for students. Parents are busy at work now, or living in different places, or parents are at odds or divorced, parents talk to their children too little, and their psychological changes are unclear.

2. The influence of social environment. We are now in the period of reform and opening up and economic development, with various ideologies. The erosion of the remnants of the exploiting classes in society. Bad elements not only commit crimes by themselves, but also often deceive, seduce and instigate a few teenagers to do bad things, so that their hearts are poisoned and they are infected with bad morals and habits.

3. The influence of mistakes in school education.

At present, "exam-oriented education" still exists in a few schools. Teachers' "heroes" are judged by students' achievements, and students' achievements determine teachers' assessment. Therefore, some teachers do not hesitate to take drastic measures to "squeeze out" students' brilliant achievements like toothpaste. As a result, those underachievers who are already self-abased feel headache, extremely bored, have no confidence in themselves and have a strong feeling of being tired of learning because of heavy schoolwork burden and frequent exams. The beautiful campus has become their most annoying place. Some class teachers are arbitrary, caring for good students and sneering at poor students, which seriously hurts their self-esteem and produces strong resistance. If they don't handle it well, they will take drastic and improper measures to retaliate against others and "defend" their self-esteem. Their apparent strength masks their inner vulnerability.

Third, adopt various forms of mental health education.

1. Schools should attach importance to students' physical and mental education. Schools should offer health education courses, and educate teenagers in psychological and sexual morality, friendship and love between men and women, legal concept and scientific outlook on life in stages. We will carry out theme activities such as youth education reading books and youth education visits and exhibitions, and invite comrades from the public security and reeducation-through-labor departments to tell students about the legal system, treat young people's "puppy love" correctly, and prevent juvenile delinquency.
