Indirect teaching: refers to a form of teaching guidance for children by teachers. Teachers don't tell children the educational requirements directly, but through appropriate intermediaries in the environment, for example, using toys, role models, phenomena or events that children care about. To achieve educational goals in a roundabout way. In this way, in children's activities, teachers have changed from lecturers to observers, collaborators, game partners, creators of activity environment and providers of materials, and the educational influence indirectly affects children through intermediaries rather than teachers.
