Pedagogy is a practical subject, and its fundamental purpose is to change and optimize educational practice. Educational theory is the overall reflection of educational practice. It comes from educational practice and can return to practice, guiding people's educational practice and promoting the development of educational practice.

Rational statement

Educational theory is a rational statement of various educational practices that human beings are engaged in.

Effective guidance

Educational theory should not only rationally tell people what education is, but also return to practice to guide people how to do it.

Promote educational reform

The role of educational theory in promoting educational reform is mainly reflected in three aspects: evaluating reality with "rational scale", predicting, designing and planning future education, relying on the power of public opinion created by theory, and calling on society, especially the education sector, to participate in educational reform.
