This study focuses on clarifying the fundamental issues of managing teaching activities at secondary schools in Binh Tan District, Ho Chi Minh City, in the direction of digital transformation. The main objective of the project is to systematize the theoretical and practical basis of teaching at secondary schools in the direction of digital transformation, assess the current status of managing teaching activities at secondary schools in the direction of digital transformation, and propose effective management measures to improve the quality of teaching in the direction of digital transformation. The results of theoretical and practical research on 120 people who are managers and teachers in some secondary schools in Binh Tan district, Ho Chi Minh City, show that, despite efforts in management, there are still many limitations and challenges that need to be overcome. Proposed measures focus on improving the capacity of managers and teachers, improving facilities and teaching equipment, along with strengthening coordination among stakeholders.
