The monograph presents a system of pedagogical design of information and environment for the training of future social educators in the digital transformation, which provides a personalized approach to learning, increases the level of information and digital competence, provides effective communication and collaboration within the environment in mixed and distance learning. The main trends in the development of education in the European space, the role of digital transformation and its impact on the training of competitive professionals are analyzed.

Theoretically substantiated and defined stages of designing an open information and educational environment for the training of social educators: analysis of the educational process in higher education, analysis of educational resources, requirements for the formation of information and digital and professional competencies of future social educators, construction of structural and functional model of open information and educational environment, selection of technological platforms and software tools, selection of electronic content, design of educational processes using an open information and educational environment. A system of pedagogical design of open information and educational environment for training future social educators has been developed, which provides a personalized approach to learning, increases the level of their information and digital competence, provides effective communication and collaboration within the environment in mixed and distance learning. To develop a system of pedagogical design, the ADDIE methodology was used, which determines a flexible, continuous process of improvements and iterations. Indicators for assessing the quality of an open information and educational environment for the training of future social educators in a mixed and distance learning environment have been identified. There are five levels in the developed structure and model of information and digital competence of the future social educator (obligatory level “A” - Analyst, sufficient levels: Integrator (B1), Expert (B2); high levels: Leader (C1), Innovator (C2) and six areas - professional development and self-improvement, professional communication and interaction, information literacy and work with data, secure use of digital resources, formation of digital competence of personalities, digital selfmanagement.
