A Four-Dimensional Framework for Analyzing the Boundaries of Social Media Engagement in K12 Educational Scenarios

Social media, as an innovative communication medium in the digital era, is reshaping the ecological pattern of education governance with subversive power, especially in the field of K12 education, and its influence deeply penetrates into various aspects such as teaching management, home-school interaction, and student development. Using Lasswell's "4W" analysis method, we reveal the blurring of boundaries among teachers, students, parents, educational administrative organizations, platforms and other subjects in terms of "subject-content-space-time", such as the leakage of teachers' privacy, parents' overstepping of their authority to intervene, and students' misbehavior on the Internet. The proposed boundary regulation path of "hierarchical governance - technological empowerment - collaborative parenting" aims to balance the openness and normativity of education, and provides theoretical references and practical solutions for K12 digital governance.
