The article describes the changes in the modern socio-economic environment, which affect the digitalization of society, including the socio-educational sphere. On the basis of the authors’ proposals for the development of the concept of “information-educational systems”, mathematical models for their description and mechanisms for analysing their essential characteristics determined by modern processes of development and digitalization of society are indicated. Through the example of using elements of the theory of dynamic deductive databases and the theory of neural networks, the article describes mathematical models that adequately reflect strategies for the development of people and stable small groups, as well as large dynamic human communities, on the basis of which recommendations are proposed for developing such strategies. The results can be used in the pedagogical design of various models of educational activities and information and educational systems for various purposes, including education management and direct training. It also seems that the mechanisms and features of information and educational systems described in the article will allow us to establish an evidence-based educational policy at various levels in the context of digitalization

With the digitalization of society based on the transition to digital economy and education, the article highlights the necessity of replacing traditional school with the digital one. The article considers digital school to be a pedagogical phenomenon rather than a technological one and suggests solutions to provide every learner with the required (documented in the approved educational program) educational level at every stage of school and to develop their own unique potential by taking advantage of digital learning. The authors conclude that transition to digital school is a digital transformation of schooling at every stage.

The paper analyses media consumption in Russia and media business strategies. The authors describe the media environment and identify the central trends typical of the transition to digital communication in society. The research approach implies evaluating the volume and distinguishing features of information consumption using the main media resources (the Internet, television, radio and print media). The information and empirical base of the research include the data of the Mediascope analytical agency, the statistical data provided by the Russian Federal State Statistic Service (Rosstat) and the results of research studies performed by consulting companies for the period of 2003-2017/2018. The paper presents the dynamics and specificity of transformation in the media environment and discusses a range of trends in media consumption: such as communication technology development; changes in the structure of media consumption; an increase in online advertising; a gradual transformation of media, etc. The results obtained show that the share of organizations and households in Russia that use the Internet in their work is constantly growing, but this growth is uneven and heterogeneous. Our findings prove that there are age (generation) differences in using traditional and new media, and the frequency of using information resources is changing.
