Moving from a"Digital Island"to an Expanding"Data Ecosystem":Digital Transformation of Teacher Education
Collaborative teacher education development is important for improving the quality of teacher education in weak institutions.Some studies have explored the ideal model of collaborative teacher education development based on ecological systems theory and actor-network theory,and found that heterogeneous subjects and negotiation of interests are essential.In contrast,the recently adopted"group model"points to the homogeneity of subjects and the unidirectional nature of benefit export,which are distant from the desirable state of collaborative development and may limit the scope of helping subjects and affect the willingness of helpers to continue to participate.In order to change the current situation,this paper proposes to expand the scope of subjects and promote efficient interaction among them with the"expanded data ecology",which can adapt to the higher requirements of"new normal construction"for teachers'literacy.In order to implement the new vision of"expanded data ecology",the data network can be expanded based on dynamic matching and conditional reciprocity;the cognition can be continuously expanded based on collaborative tracking data;the guarantee system is constantly updated based on the real-time data of collaborative quality improvement.
