The purpose of the research is to determine the needs of teachers and concretize the structural, content, technological and ergonomic characteristics of the new regional platform for the implementation of additional subject training of schoolchildren in the Krasnoyarsk region, functioning in a digital society. Despite the fact that today online education resources are gaining more and more popularity, providing unlimited access to sources of knowledge for all segments of the population, their use in the real educational process, including additional subject training of schoolchildren, is not gaining such popularity as among the adult contingent of students. This fact is due to the characteristics of the younger generation, as well as such characteristics of existing platforms as rigid fixation of content and procedural components, mass character without the possibility of adjusting to the needs of a particular student, school, program or the author’s position of a real teacher. In this regard, there is a need to develop such a platform that will meet the needs of school teachers, and innovative teachers, interested in the development and productive use of digital educational resources in the multilevel training of schoolchildren in the context of distance education will participate in its development and filling. It seems that such an environment will increase the innovative potential of the Krasnoyarsk region in the field of general education, positively affect the image and competitiveness among other regions of the Russian Federation.Materials and methods.
