Features of the university’s pedagogical specialties students’ preparation for the blockchain technologies in professional communications use

Problem statement. The blockchain technologies properties indicate the significant potential of their application to increase the effectiveness of professional communication among teachers. However, most modern teachers do not use such technologies in all forms of professional interaction. It is necessary to conduct research aimed at solving the problem of finding approaches to the development of existing systems for training students of pedagogical specialties of universities, both in the direction of using blockchain technologies as an object for study, and in the direction of mastering additional professional communication techniques involving the use of blockchain technologies to ensure transparency, reliability, decentralization and trustworthiness of pedagogical interaction. Methodology. Continuous monitoring is carried out on how, in what cases and for what purpose teachers use blockchain systems, as well as studying the degree of practical effectiveness of the proposed approaches and tools, including the content of training and a system of practical tasks, to form students’ needs for the use of such technologies in professional communications. Results. An extension of the goals, content, methods and means of training future teachers has been developed and shown using examples, aimed at familiarizing them with the possibilities and advantages of using blockchain technologies in professional communications. The features of using blockchain technologies for such communications in different forms and levels of education have been identified and systematized. Conclusion. The proposed training of future teachers to work with blockchain technologies helps to increase the effectiveness of their subsequent professional communications, especially those carried out in a telecommunications format. This can be achieved by increasing transparency, stability and reliability of information exchange between all educational process participants.
