"How was childhood institutionalized by school"is a major prerequisite issue,which has important value for childhood development.Based on the new institutionalism integrated analytical framework,in the process of childhood being institutionalized by the school,the common interests provided strong legal protection through the mandatory power of child labor laws and education laws;the practice norms restrained and shaped the behavior of parents and children through the discipline and internalization of social expectations and school discipline;and the shared concepts have formed a good social and cultural atmosphere through the habituation and objectification of institutional cognition such as the dichotomy between childhood and adulthood,and the belief that childhood should be spent in school,and so on.The childhood institutionalized by school has also produced some consequences,including diminishing marginal benefits,the standardization of childhood patterns and the unequal power relationship between childhood and adulthood.In this regard,it is necessary to always take the life and development of children and childhood as the fundamental purpose,develop children's subjectivity,reaffirm the value of diverse childhood,and explore traditional Chinese childhood concepts.
