The article summarizes the essence of the category "model", presents the main types of models used in pedagogical research: structural, functional, structural-functional models. The basic requirements for the construction of these types of models are also given. The experience in building a model and designing a cloud-based learning environment of educational institutions (both higher and secondary) is analyzed. A structural model of a cloud-based learning environment for bachelors in software engineering is presented. Each component of the cloud-based learning environment model for bachelors in software engineering is described: target, management, organizational, content and methodical, communication, technological and effective. The model of interaction of participants of the educational process in the cloud-based learning environment is developed. Forms, methods, and tools (both traditional and cloud-based) of content and methodological components of the cloud-based learning environment's structural model that can be implemented in this cloud-based LMS are described. Forms of an educational activity (classes, practical training, independent work, control measures, as well as research work of students) are considered. The types of lectures that can be conducted in a cloud-based learning support system are described: lecture-conversation, lecture-discussion, video lecture, lecture-consultation, and lecture-presentation. The types of practical training offered in the cloud-based learning support system are described: laboratory work, workshop, seminar, and webinar. Different types of independent work and assessment are considered. The research work of students as a form of educational activity provided by the curriculum of bachelors in software engineering is singled out. The main teaching methods that can be implemented using a cloud-based LMS to support the training of bachelors in software engineering are considered. It is generalized that the cloud-based learning environment should solve all the main tasks facing higher education institutions.
