Examining the construction of collaborative parenting mechanism of primary and secondary school families,schools and society from the perspective of overlapping influence domain theory,it is found that there are a number of problems in the current school collaborative cooperation,including the failure to pay sufficient attention to students'' development in the process of the linkage of the collaborative education mechanism, the lack of effective integration among the main bodies of the collaborative education mechanism, the lack of effective communication and dialogue among the main bodies of the collaborative education mechanism and the ineffective linkage of the collaborative education mechanism, and so on.The main reason for this is that the main body of the collaborative cooperation is the family, school and society.Analyzing the reasons,it mainly lies in the lack of awareness of the participation of multiple parties in the synergistic subject,the bias of the educational concept of the synergistic parenting mechanism,the lack of effective communication channels and the lack of the guarantee mechanism in place.Accordingly,suggestions are made in terms of top-level design, home-school growth community, division of responsibilities and collaboration mechanisms,and institutional safeguards,with a view to changing the problems of the existing home-school-society collaborative parenting mechanism and constructing a home-school-society collaborative parenting mechanism for primary and secondary schools based on the theory of overlapping domains of influence.
