The reference group is an example group. When an individual takes a certain group as a yardstick and makes his behavior reference, then this group is called a reference group. Reference group plays a prominent role in primary school children. It is regarded as a criterion in children's minds, and children use it to evaluate themselves and others, and gradually form their own attitude system and behavior habits, which becomes an important basis for character formation.

(2) Pay attention to the influence of informal groups among students.

Informal groups in the class also play a role in encouraging, weakening, restricting or inducing individual behavior to a great extent. It is also closely related to the attitude, behavior habits and even personality formation of primary school students, and educators should pay attention to it.

(3) create a good group atmosphere

This mainly refers to the class collective atmosphere, or ethos. First of all, the atmosphere of a class is closely related to the atmosphere of its school. Influenced by the atmosphere of the whole school and even greater environment. If the whole school generally has a strong learning atmosphere, then the students in a certain class will obviously contrast with the overall atmosphere and feel the pressure from the outside world, so we should adjust and improve the style of study. Creating a good collective atmosphere depends on the following points: ① At the beginning of collective establishment, clear collective objectives and management systems should be established; (2) the class teacher's exemplary influence and prestige, as well as flexible, objective and fair management methods; (3) organize class members to participate in activities consistent with the collective goals, such as theme class meetings and learning competitions, so as to improve class members' self-awareness of the collective goals and make them consciously pursue and maintain the collective goals.

(4) Educate students according to their personality characteristics.

(1) The main methods to understand personality characteristics.

Children's personality can be understood through observation, conversation and case records.

(2) According to students' personality characteristics, carry out corresponding education.

Everyone has his own characteristics in personality, that is, showing specific advantages and disadvantages. When they live in a group, they will show some common personality characteristics. Education should first pay attention to using the common character strengths of the group, and try to help them give full play to their own advantages and overcome their personality weaknesses.

Personality cultivation should take into account the commonness of children, but at the same time, personality cannot be ignored. Here mainly refers to the following two situations: first, the children at both ends of most students, that is, the good students with particularly excellent personality or the poor students with mostly poor quality, have personality compared with most children; Second, in comparison, each child has a combination of personality advantages and disadvantages different from others.
