在教育资源差异的背景下，从县城到市区重点中学，部分家庭因陪读的共同目标形成了“陪读圈”。在陪读的过程中，家长们进一步形成了亲密的非正式群体，在陪读结束后保持着亲密稳固的关系；而孩子们却并没有通过陪读而结成非正式群体，他们保持着自己的原有关系。因此，家长和孩子的交往状况呈现出显著差异。

本文基于非正式群体的视角，以互动论为基本范式，对一个县域陪读圈进行案例研究。研究发现，情感是形成和维持非正式群体的重要因素，家长们基于共同的行为法则，在大量的日常交往互动和特殊情境的仪式性互动中，产生了深厚的情感联结。孩子们在学生化儿童的日常生活实践中被单一的学生角色固着，缺乏互动的机会，因而缺乏形成情感联结的客观条件。孩子们在校内有各自的小圈子，满足了交往的情感需求，因而不具备建立关系的情感需求；在有限的互动机会中，孩子们因家长在场所以遵守着符合学生角色的规范，并未形成共同的情感体验，所以没有形成非正式群体。

In the context of the disparity in educational resources, some families from the county to the major urban secondary schools have formed 'accompanied study circles' with the common goal of accompanied study. In the process of accompanied studying, the parents form further close informal groups and maintain close and strong relationships after the accompanied study has finished, whereas the children do not form informal groups through accompanied studying and maintain their original relationships. As a result, there are significant differences in the interaction status of parents and children.

This paper presents a case study of a county accompanied study circle based on the perspective of informal groups and using interactionism as the basic paradigm. The study finds that emotion is an important factor in the formation and maintenance of informal groups, and that parents develop deep emotional bonds based on shared behavioural laws, in a large number of daily interactions and ritualistic interactions in special contexts. The children are entrenched in the everyday practices of studentised children in their student roles and lack opportunities for interaction and therefore lack the objective conditions for forming emotional bonds. The children had their own cliques within the school, which met the emotional need for interaction and therefore did not have the emotional need to build relationships; in the limited opportunities for interaction, the children played the role of conforming to the norms of the student role due to the presence of their parents, and did not form a shared emotional experience, and therefore did not form an informal group.
