The dissertation presents a theoretical foundation and a new solution to the problem of using a cloud-based learning environment in the training process of future computer science teachers. The concept of a "cloud-based learning environment" is interpreted as a system of digital tools (hardware, communication, virtualized). These tools operate in accordance with the principles of cloud computing and provide universal access for students to data, and computing resources, in order to achieve the educational outcomes outlined in the curriculum. Based on the source base, it is substantiated that to design the researched environment means to analyze and determine the target, content, and didactic requirements for the training of education applicants in it. The concept of "Administration of a cloud-based learning environment" has been clarified. It is interpreted as a set of measures related to the design, deployment, management, and maintenance of its components (services, platforms, infrastructures), as well as supporting the activities of applicants in it. The conducted research is aimed at the development of cloud-based learning environments of higher education institutions under the conditions of education reforms. This necessitates the development of scientific, technical, and methodological support to effectively implement these environments.
The study of the experience of training future informatics teachers shows that in universities of Ukraine, the EU, and the USA, the study of the concepts and problems of using modern cloud technologies are relevant. Based on the analysis of psychological and pedagogical features of activities in cloud-based environments, it is substantiated that mass open online courses are an effective form of providing educational resources. The general research methodology of the problem of developing theoretical, technological, and didactic principles of design, administration of cloud-based environments, and their use for training future computer science teachers is presented. The prerequisite for the training of competent specialists in the fields of education and information technologies, has been formulated. The tasks of the pedagogical experiment and the basis of the experimental and research work are indicated. A description of each stage of the experiment is provided. In the dissertation, modeling of a cloud-based learning environment for future computer science teachers was performed. So the conceptual, didactic, service and administration environment models were substantiated. In accordance with these models, didactic (ubiquity, invariance, monitoring, control of educational activities, possibility of participants interaction in the educational process, resource manageability, compliance with various models, perspectiveness) and technological-procedural (availability, functionality, standard network protocols support, distribution legality, configuration flexibility, integration potential, controllability, and security) selection criteria are determined as components of the environment of cloud platforms and services. It was established that providing support for the educational process involves a technical and methodical combination into a combined cloud of platforms (public and private) implementing all service models.
