The dissertation considers that there is an inner relationship between various elements of e- ducology and a given culture, which produces"the culturalcharacter of educology". Educational problems have factual bases, but their nature should be considered as subjectivity, valuableness, and historicity, which distinguish educational problems from educational facts and related prob- lems of other disciplines. Besides having a logical feature of scientific concepts, the nature of edu- cational concepts should be considered as historicity, normativity, valuableness and expressivity. Educological activity is a kind of subjective activity. The subjects of educology are not only the subjects of knowledge, but also the subjects of value and practice. Educological works are products of their whole soul life, which embody their life and social ideals.
