Suhomlinski believes: "Without self-education, there is no real education." "I firmly believe that education can be true only by encouraging students to educate themselves." "People are used to calling adolescence and early youth' difficult ages'.

During this period, students are developing rapidly in physical, intellectual and moral aspects, so there will be many difficulties before educators. Only by organically combining education with self-education can we successfully overcome these difficulties. "Adolescence and early youth are the ages when personality is formed in intelligence, morality and social thought.

At this age, the normal intellectual development of students depends on whether the process of self-formation is profound in all fields of activity and collective relations, in intellectual life and labor, and in the formation of moral beliefs. A teenager, only when he learned not only to seriously study the world around him, but also to seriously study himself;

Only when he tries to understand not only the things and phenomena around him, but also his inner world; Only when his spiritual strength is used to make himself better and more perfect can he become a real person.

It can be seen from this series of discussions that Suhomlinski regards students' self-education as an indispensable and extremely important part of school education.

The philosophical principle of Marxism tells us that external cause is the condition of change, internal cause is the basis of change, and external cause can only work through internal cause.

The material layer and system layer of school education only provide material basis and behavior norms for students' character cultivation. Without the concrete "internalization" process of students' own moral cognition, moral emotion, moral will and moral behavior, what will happen if the skin does not exist? All education will be in vain, and the formation of students' good moral cultivation is out of the question.
