Teacher Environment Setup is the process of creating an environment within TeamTV for teachers to set up and manage their educational courses. To set up a teacher environment, the coordinator needs to provide the necessary information, such as the course name, teacher name, and region. The coordinator then informs TeamTV to create the environment. TeamTV creates the environment and adds both the teacher and coordinator as administrators, allowing them access to the environment. Both the teacher and coordinator will receive invitations to become administrators of the environment.
