Every year the problem of higher educational establishments’ modernization, introduction of the newest methods and strategies of educational process reorganization, estimation of achievements in the context of information technologies becomes more and more urgent. The situation with the COVID-2019 pandemic has demonstrated the need to involve additional information approaches to teaching within the system of blended learning in higher educational establishments. As a result, the question arises: what mechanisms can be used to make learning effective? The article reveals the concept of “microlearning” as the latest approach in education and identifies its key tools in formation of English-language competencies in university students. The study found that microlearning can be an effective complement to traditional learning, as it extends the learning process beyond the classroom on the basis of information technology, allows consolidating virtually and deepening the knowledge gained during practical classes, and provokes students to daily communication outside the establishment through social network. Moreover, we propose a strategy for implementation of microlearning on the example of the educational process at Kherson State Maritime Academy through interaction of practical classes in the line of communicative-competency approach, virtual and online learning on the principle of rotation.

ОЦЕНКА ЭФФЕКТИВНОСТИ УТИЛИЗАЦИИ ВТОРИЧНЫХ ЭНЕРГОРЕСУРСОВ В ЭЛЕКТРОХИМИЧЕСКИХ ЭНЕРГОУСТАНОВКАХ ТРАНСПОРТНЫХ СУДОВ АННОТАЦИЯ ESTIMATION OF WASTE ENERGY UTILIZATION EFFICIENCY IN ELECTROCHEMICAL POWER PLANTS OF TRANSPORT VESSELS ABSTRACT Analysis of waste energy utilization efficiency in electrochemical power plants based on proton exchange membrane fuel cells for transport vessels is done in this article. Quantitative estimation of waste heat energy flow in electrochemical power plants from 100 kW to 2000 kW operated on pure hydrogen is the main aim of research. Usage of hot water or saturated (or slightly superheated) steam at outlet from fuel cell as heating agent is considered. Total fuel mass and capacity for one-way trip are estimated for electrochemical power plants operated on pure hydrogen, methanol and liquefied natural gas. Potentially-enable quantity of power resources obtained through utilization of heat power and slightly superheated steam is come out. Analysis of these indexes makes possible justification of rational engineering choices at ships' conceptual design and elaborates recommendations of keeping options for different variants of waste energy utilization in electrochemi-
