Pedagogy is to analyze and study practical experience with rational thinking, find out the objective laws behind successful experiences and failed lessons, and sum them up into scientific theories. Educational practical experience is one of the foundations of learning, researching and developing pedagogy.
Compilation is mostly a collection of educational practical experience, which is only superficial, partial and individual concrete experience, and has not yet revealed the educational law. Of course, pedagogy is inseparable from the practical experience of education, and there are rules in experience. We should attach importance to educational experience, raise educational practical experience to a theoretical level, and sum up educational laws from educational experience, thus enriching and developing pedagogy.
