ABSTRACT. In the paper questions about using Distance Learning Platform based on the SCORM standard for definition structure of teaching materials and creation per-sonalized learning path for students are discussed. The authors made research of teaching way of the discipline “Information Technologies” for foreign students on the basis distance learning platform. A proposed strategy must take into considera-tion national, language, psychology and cognitive features of students, different their skill levels not only from information disciplines but also from other general science subjects. Number of reasons conditions the relevance and practicability of the study. First, learning of foreign students in the maritime academy requires creation of ac-cording conditions for them, which help better adapt to learning process. Second, scientifically planned and methodically determined distance learning can help to students to be not cut off educating when they have practice training in remote are-as. Efficient use of education distance form depends on a built learning manage-ment system (LMS) and information technologies by which it had been realized. Application of SCORM-package improves cognitive orientation, its accessibil-ity, variability, creative education aspects and contributes to form a public usable web-based learning environment. SCORM-packages have been developed taking into account a standard, so can be used for e-learning system based on different platforms. Without taking into account that involved training course of marine professional was oriented to foreign students, the research results can be applied for students’ teaching in other areas, because usage of SCORM standard allows to develop learning course independently of software platform and some topics are general for the forming of information culture of trainees.

ABSTRACT. The movement of the system "tractor - transport-technological machine of variable mass" is considered in the context of the movement of the center of mass of the system, given the equality of the internal forces of this system among them-selves. Using the obtained dependencies, it is possible to determine the effect of changes in the acceleration of the center of mass of the transport-technological unit with variable mass on the load of the tractor's transmission parts. The tractor control algorithm is synthesized in the rational area of transmission elements loading and a program for its implementation in the field is developed. The developed application is an information system, the purpose of which is to inform the operator of the presence of stress in the transmission`s elements of the tractor, which cause it overloading and, therefore, reduce the resource of its parts. If the strength condition for fatigue failure is not met, the operator of the transport-technological unit is offered to change the driving mode to reduce the load on the transmission elements

ABSTRACT. Decision making in the economy demands tools to find the most effective, cost-affordable and optimal solutions.

ABSTRACT. The purpose of the study is to develop the methodical recommendations for test-designers to cope with challenges of organizing on-line assessment process. In order to achieve this goal we have to reveal the strengths and weaknesses of e-assessment activities based on analysis of the universities practice. To find out students’ attitude to the issue of the study we have drawn up the questionnaire. The survey results confirm that e-assessment is rated as priority activity by learners thanks to individual approach to teaching/learning process, easily accessible and fast feedback, as well as interactive methods of implementation. Reviewing practical experience of Kryvyi Rih National University (KNU) and Donetsk Law Institute of the Ministry of Internal Affairs of Ukraine (DLI) and summarizing statistical data of the survey we have developed methodical support for designing e-assessment activities which involves: to determine intended recipients and the purpose of testing; select appropriate instruments and e-platform; specify forms of feedback; clarify the tasks; provide knowledge base for operating e-tests etc. Despite plenty of studies in this domain the test-designers and test-takers face to typical difficulties while operating e-assessment, and there is lack of research providing methodical practicalities in this field. To address learners’ and lecturers’ needs we have developed the methodical recommendations, which might be used in the drafting of e-assessment tests for students of different specialisms.

ABSTRACT. The article deals with the problem of studying students’ views of the instrumental competence of journalists (ICJ) as a predictor of their professional development. The urgency of the issues under consideration is justified by the need to use the EDM system in higher education institutions, which is caused by the contradictions between the contemporary demands of the journalism labour market and the professional training of graduates. In this regard, the proposed study is aimed at finding possible causes for existing contradictions. Based on the results of the study of educational documents and the review of the scientific literature, authors identified the 23 information computer technologies skills that are required for journalists to perform professional tasks. The students of the first year of study (N=207) of three universities were asked to evaluate the importance/necessity of these ICT skills. The used in the survey questionnaire, that consist of demographic and Likert-type questions, provided an opportunity to rank the importance of assessed skills and to identify through factor analysis four significant groups of ICJ-components. They are web publishing skills, cybersecurity skills, multimedia content preparation skills, and media promotion tools. Authors compared the results of the first-year students’ survey with the results of the analysis of educational programs in the speciality "Journalism" (of Ukrainian universities) and identified the directions of possible improvement of the organizational component of journalistic education. The conclusions justify the using of illuminated research methodology to develop a system of analysis of educational perception data and propose prospective directions for further research.

ABSTRACT. The article deals with the problem of using modeling in social statistics courses.

ABSTRACT. The current state of digital technology in domestic business is dramatically different from the world. The use of world-class methodologies to determine the digital intensity (maturity) index with appropriate indicators is not acceptable for domestic realities because of the low overall level of use of digital technologies in business, both industrial and commercial. In view of these issues, the task of developing our own, national methodology for determining the index of digital transformation of a business with relevant indicators is relevant and important. Such a methodology should take into account the current state of affairs in Ukraine, reflect an in-depth analysis of the level of digital transformation of business structures, while being flexible in order to respond promptly to new phenomena and the emergence of new digital technologies. Calculation of the Index based on the real results of digital maturity of domestic business structures will serve as a driver for further practical steps to enhance their digital development. The article describes the method of calculating the Digital Transformation Index (HIT); a list of multilevel recommendations for increasing the HIT index has been formed, their gradation is displayed; the results of clustering of business structures by the level of digital maturity are demonstrated; specific recommendations for raising the HIT for the enterprises of each of the clusters formed.

ABSTRACT. The paper aimed to study the readiness of the existing e-learning environment for the organisation of English-language learning among Ukrainian and international students on the example of a technical university in Ukraine. The need for Eng-lish-language training was explored by interviewing students with keen interest, level of English proficiency, motivation, preferred forms of learning, and a will-ingness to incur additional costs for such learning. About two-thirds of those surveyed showed interest in English-language education. About one-third of the students surveyed have the necessary level of preparation and are also prepared for additional financial expenses. About one-third of the students may also join English-language studies if they fulfil certain prerequisites. Expected employment progress is the main motivation for joining the English-language program. The readiness of the existing learning environment was tested by analysing the organ-isation of access to English-language teaching materials, assessing the demand for different electronic resources, as well as the ability to take into account the learning styles of potential Ukrainian and international students in the educational process.

ABSTRACT. The article deals with the issues of improving the technological training of trans-lators by introducing innovative elements within special courses or modules. A unification of the study of the same key operations of managing terminological resources in automated translation systems, which are used to support both sim-ultaneous interpretation and translation, is proposed. The analysis of software products from the category of CAI (Computer-Assisted Interpreting) and CAT (Computer-assisted translation) for the revealing common characteristics in the aspect of working with terminological resources is made. An attempt has been made to optimize the technological training of translators for performing opera-tions of search, selection, structuring, import, export of terminology, which is or-ganized in the form of specialized terminological bases. The expediency of study-ing by future translators at least one of the software products related to САІ, one to cloud-based САТ, and one to desktop САТ is justified. The principles on which the process of optimizing the content and organizing the technological training of translators should be based are determined.

ABSTRACT. The market price for electricity at the energy exchange is mainly determined by supply and demand. For many market participants, electricity price forecasting is an important competitive factor. Previous research primarily predicted based on demand. In times of renewable energies this mantra is no longer sustainable. This study primarily looks at the supply-side prediction of the electricity price with the help of deep learning artificial neural networks and thus makes a contribution to the literature. Autoregressive models and regressions serve as benchmarks.

ABSTRACT. Current practical experience in measuring the effectiveness of organizational development activities is largely based on the evaluation of surveys. In this paper we introduce an approach based on artificial neural network with elements of fuzzy approach and genetic algorithm for manag-ing organizational development. Genetic algorithm was used for the de-scription of parent-child relationships, instead the fuzzy logic for the han-dling of complex non-linear describable relationships. We supplement the previously known organizational development measures with technology-based ones in order to increase the degree of automation of the measures of organizational development in practice. In order to map the data system of organizational development, we have arranged thematic subsystems with causal relationships and respective parameters. In this paper we describe the procedure and exemplary extracts from the designed system. This paper is intended as an orientation for other scientists who are researching the same topic and are interested in the current status.

ABSTRACT. Modern information and communication technologies allow to successfully use the methods of effectiveness measurement of various processes in particular in the field of education. From our perspective, success in the implementation of individual educational trajectories by university students requires the assessment model based on the use of modern information technology. In this article, we propose our own methodology for such measuring. It takes into account the entrant's competitive score and student's rating score. The user of the created system can choose the necessary information by criteria such as higher education degree, the form of study, department, and using the graph visualize the implementation of each student's educational trajectory. The presented methodology allows for evaluating objectively the quality of students` individual study plans and can be used in the development of universities rating and ranking criteria.

ABSTRACT. Swift changes in society, related to sciences technicians’ development, technologies, by the increase of general volume of information, pull out new requirements to maintenance, structure, and quality of education. It requires teachers to diversify a tool in the direction of the increase in possibilities of the use of mobile technologies and computer systems. Lately in the world, more attention spared to the use of mobile learning, which in obedience to «Recommendations of UNESCO on the questions of a policy in the area of mobile learning» foresees the use of mobile technology, both separate and together with other by informational computer technologies. [1]. Mobile learning allows using the open informational systems, global educational networks, unique digital resources which belong to different educational establishments and co-operate with each other. The use of existent educational resources and creation of own, on the basis of academic resources from informative space, allows to promote the interest of students to the study of physics, to take into account the individual features, and also features of region and framework of society of the country. During the last years in Ukraine competency-based approach to the organization of studies certainly one of basic. The new Education Act addresses the key competencies that every modern person needs for a successful life, including mathematical competence; competence in natural sciences, engineering, and technology; innovation; information and communication competence [2]. This further emphasizes the importance of providing students with quality physical education and the problems associated with it. Using mobile technology in professional teaching work, the teacher has the opportunity to implement the basic principles of the competence approach in teaching physics. An analysis of the data provided in the official reports of the Ukrainian Center for Educational Quality Assessment showed that the number of students making an external independent assessment in physics and choosing a future profession related to physics has decreased significantly. This is due to the loss of students' interest in physics and the complexity of the content of the subject, as well as the increase in the amount of information that students need to absorb. In this article, we explore the possibilities of mobile technology as a means of teaching physics students and give our own experience of using mobile technology in the process of teaching physics (for example, the optics section in primary school).

ABSTRACT. This thesis describes the insights from the analysis of the comparative evaluation of open learning methods in organizational education and will be of most interest to researchers and practitioners from non-university backgrounds. The approaches considered focus on the selection of solutions based on the methods, which can be individually adapted in the future and selected, for example, by using artificial intelligence technologies to achieve organizational goals without human intervention. In this paper we describe the evaluation methods of the learning forms based on the principles of andragogy and consider the software specifics of investigated methods. The obtained conclusions show that the open source course, online learning communities, training with virtual reality and artificial intelligence can be successfully implemented separately and in combination according to the purposes of organizational development. However, learning with artificial intelligence has also a great potential due to the extensive knowledge base and diverse ways of knowledge mediation.
