Abstract: This article discusses the features of forming a personality-developing educational environment in the context of global digitalization. The concept of the digital educational environment is revealed in the context of its personality-developing nature, the basic scheme of the functioning of the subject-generated environments in the digital educational environment is substantiated, the factors determining the personality-developing potential of the digital educational environment are highlighted, as well as the features of the teacher's activity on the formation of the developing the environment by digital means in the refraction of traditions and innovations. The traditional understanding of the educational environment is undergoing a significant transformation due to digitalization. The study showed that the formation of a developing digital educational environment should be carried out with a mandatory emphasis on the subject-generated characteristics of the environment, resolving the contradiction between the diversity and openness of potentially developing resources, on the one hand, and the uncertainty, non-obviousness of the results of interaction of subjects, on the other hand. For the teacher, the digital educational environment acts as a discrete education, whereas for the student, it is a single structured digital space (a single environment). A teacher's activity is the formation of a developing environment by digital means, giving it developing functions associated with pedagogical competence to fill the environment with appropriate situational and event content, contributing to the generation of environments in education by students themselves and filling them with authentic meaning. The teacher's specified competencies depend on the completeness of the theoretical understanding of the peculiarities of the emergence of subject-generated environments in the digital educational environment.
The scientific novelty of this research lies in the fact that, for the first time, a personality-developing digital educational environment is considered through the concept of subject-generated environments, which brings the student's personality to the center of relevant educational projects. The development of the student's personality in the DEE is a multifactorial and open subject-dependent process with variability of resources for self-change, the research attitude corresponding to the post-non-classical stage of the development of science.
