The earliest document on education in the world is Xue Ji.

The Book of Learning is one of the rites. Xue Ji is the earliest monograph on education and teaching in China, the textbook of ancient education, and one of the earliest, most systematic and theoretical educational monographs in China and even in the world.

In the examination, the exposition of Xue Ji education is also an important test point. For example, in the Book of Learning, it is stated that "it is forbidden to say that it has not been sent; When it can be called; Don't care, call Sun;

Looking at each other well is called "friction", that is, preventing students' mistakes when they don't happen, which is called prevention; Timely education is called timeliness; Education that does not exceed the talent and age characteristics of the educated is called orderly; Learning from each other's strengths is called observation.

The earliest western educational work "The Principle of Eloquence";

The Principle of Eloquence is the work of quintilian, an ancient Roman thinker. The definition of "orator" in ancient Rome is "educated person", so quintilian thinks that the purpose of education is to cultivate educated orators. The Principle of Eloquence is a concrete exposition of the cultivation of orators, the first systematic educational theory work in the West and the first work on teaching methods in the world.

Quintilian emphasized the idea of teaching students in accordance with their aptitude, and thought that the unified requirements for students should be combined with teaching students in accordance with their aptitude. Therefore, he used the method of teaching students in accordance with their aptitude as a supplement to his idea of teaching in different classes, which gave great enlightenment to later education. We can see the shadow of quintilian in Comenius' thought.
