This study explores technology-based learning management strategies in senior high schools in North Sulawesi Province to address the challenges of 21st-century educational disruption. The primary focus of this research is to identify the planning, implementation, and evaluation steps of learning in the post-digital era, as well as the supporting and inhibiting factors during the implementation process. Using a descriptive qualitative approach, data were collected through observations, interviews, and documentation from seven public and three private senior high schools. The findings indicate that schools successfully integrating technology possess adequate infrastructure, strong leadership from principals, and continuous training for teachers. Key supporting factors include collaboration with the Department of Education and external stakeholders, while challenges involve limited infrastructure and teachers' digital competencies. This study underscores that integrating technology through the frameworks of the Technology Acceptance Model (TAM) and Task-Technology Fit (TTF) can enhance learning quality and prepare students for the post-digital era.
