Introduction of information and communication technologies in the educational process has resulted in the emergence of innovative teaching techniques, new software and technologies. One of the effective means of distance learning is mass open online courses (MOOC). The purpose of the article is to analyze the possibilities provided by the Ukrainian online platform of the Open University of Maidan (OUM), and to compare it with other Ukrainian platforms (Prometheus, EdEra) according to certain criteria. The article reveals the main advantages and disadvantages of using MOOC both for self-development and in the educational process at higher education institutions. It has been found that MOOC provide lifelong learning and implement the principles of mass involvement and openness. They also offer free online courses and generate a certificate after their successful completion. We have identified some problematic issues which cover the imperfect system of practical tasks, the need to increase users’ motivation, the language aspect, etc. The OUM online platform is primarily intended to provide civic education for community representatives and other users. We analyzed the thematic areas of the online platform and characterized them. The courses on this platform are mainly focused on the adult audience. They increase personal, communicative and civic efficiency, develop social entrepreneurship and understanding of the global content. Also, they ensure effective interaction with the authorities. During the content analysis we found that the OUM platform has specific features. In particular, it is the ability to form and graphically represent the individual educational trajectory; the platform contains exclusively Ukrainian-language content and provides an opportunity to be informed about the course progress via email. We dwelt on the possibilities of using MOOC by students, teachers and all those who are interested in self-study.
