The three elements of education include "educator", "learner" and "educational influence". The three elements of education are independent of each other and stipulate each other, which together constitute a complete practical system.

Educator: In short, a person engaged in educational activities. Learner: Traditionally, people refer to "educated" or "students". Educational influence: that is, all the information that educators act on learners in educational activities, including both the content of information and the form of information selection, transmission and feedback, which is the unity of form and content.
