在班级中,学生不仅受到正式群体的限制,而且还受到非正式群体的控制和影响。因此,教育工作者要重视学生非正式群体,注意引导、发挥其积极效应,防止消极的影响。 In class, students are not only limited by the formal group but also controlled and influenced by the informal group. Therefore, educators should pay attention to informal groups of students, pay attention to guidance, exert their positive effects and prevent negative impacts.
