motivates people to so-called reformate the professional activities, as in basic university education system the new knowledge may very often be irrelevant or inadequate. In both cases, an important tool to meet the professional and educational needs, as well as informational requests and interest is self-education.
The present practice shows that self-education helps people not only to learn the details or specific issues of the subject, but also to find their vocation, to a certain extent to meet their communication and informational needs. The self-education feature is its help in enriching the informational human capital, which its competitiveness on the labor market depends on.
Self-education helps to enrich the informational human capital, which its competitiveness on the labor market depends on. This activity contributes to a rapid selfdevelopment that, as a result, increases the level of self-control and discipline. In the self-education process a person has the informational freedom, which allows studying the materials interesting to the subject of studying and, as a result of "free" thinking, new thoughts, ideas, plans appear and if they are developed, innovations, startups, which can be put into reality, are obtained.
No structure is willing to employ a specialist with a standard type of thinking, which was founded by the traditional form of education, so every member of society has to be adapted individually to the professional activity by maximum using the available human capital in it.
Self-education allows a person to recognize and highlight specific aspects of life, a tendency of analyzing facts, understanding of patterns, focusing on the future professional orientation needs to communicate, express their particular views about something, self-organization, commitment, anticipation of new challenges and the ways of their elimination. 2
Analysis of the Most Popular Online Self-Educational
Service Today, there are a lot of mostly free, online platforms for studying and further specializing in various fields. Among them, the most popular are online courses on topical subjects such as programming and the basics of creating a startup business, economics and economic theory, network marketing and online media. The legal issues both in the professional activities and in the daily life of a citizen, as well as the development of "basic" languages are also important for self-education. The most popular online platforms available to Ukrainian users are: Prometheus; Coursera; and FutureLearn.
Prometheus [1] is the Ukrainian public massive open online courses project. The purpose of the project is to provide a free access to the university level courses for everyone in Ukraine.
The users of this online platform have the opportunity to take courses in programming, entrepreneurship, creating and developing business, psychology and techniques of effective communication, law, management, foreign languages and others. Prometheus offers and carries out the cooperation with leading universities (the courses are given by the teachers KPI, Kyiv-Mohyla Academy, Kyiv National University), and Among the variety of online platforms for self-education and self-development for the user, there is the question of electing the most optimal and the most effective resource according to certain criteria. For a visual example, let us analyze above mentioned Prometheus, Coursera and Future Learn according to several criteria. 2.1 Online platforms allow studying a particular area or discipline as a whole; however, YouTube channels and their special videos provide more specific information concerning a particular issue or problem. Category “Education on YouTube” is getting more popular every day, which means the entertainment portal visitors like watching science-fiction and educational videos more and more.
An important positive feature of this training is a hands-on experience of leading speakers, scholars, teachers, professionals and progressive people or a presentation of the theoretical knowledge that the informational customer needs to practice more than 60%. From the psychological point of view, if in the video a person sees the personality, who is popular, who achieved great success in his work or the caller likes his appearance, then the information is better remembered and easily perceived. In addition, in such training videos we can see visual instructions how to use a particular device, gadget, to hear a detailed description, pros and cons from the first word. However, expanding horizons through the Internet, a person himself has to dig in a huge flow of resources that can detract from the core. Another important feature of educational videos is not the quantity but the quality of the material. Therefore, there are video resources that specialize in one particular direction and the best quality information is provided exactly there.
The most popular areas are: programming, foreign languages, business, marketing, consulting, medicine, chemistry, physics, biology, history, art, that is, everything related to the professional growth and expansion of the knowledge base that allows solving the required tasks and problems practically and effectively.
YouTube video provides the information from both domestic and foreign sources, which can include subtitles in other languages to facilitate the perception of the gained knowledge. That is, in five minutes you can learn that you will have to read for half an hour. So a minute and a half news clip a half-minute commercials, snippets, titles, collages, short news and interesting computer graphics contribute to a better memorization and as a result, study of a particular subject [9].
According to the publication Forbes [4], the videos of one of the leading education platforms KhanAcademy got more than 500 million views as a whole. Khan Academy [5] uses the stories, supported by key points written by hand, VSause is the charisma of a presenter, Veritasium is tricks and news reportage shooting, Crash Course is animation. Dynamic YouTube videos with constantly changing plans, short episodes with using “mental hooks” (jokes, famous savers) are a reference to the concentrated knowledge in a colorful package. They stimulate the informational requester to form some fundamental knowledge [9]. Derek Mueller, the creator of Veritasium [6], and the bright representative of online teachers believes that the best way of learning is the learning face to face. If out of half a million people, at least one of the tenth part will interest the words of the teacher, then in a few years a thousand professionals enthusiastic can be received [9].
The Ukrainian educational content on YouTube has a rapid development. There are also tracings of the foreign projects in Russian. For the experiment, on the YouTube search the keyword “online education” in different languages was entered. The leaders of these videos were English-speaking countries, Spain and Russia (Figure 2). Germany, Ukraine, Arabian countries, Italy, France, China, Poland and the Czech Republic have also high rates.
Overall, the rates range from 7,770 videos to 12.2 million videos and are growing continuously (Figure 3).
Assessing the first videos from the proposed list after the search, the number of views shown in the diagram was separated (Fig. 4). The absolute leader remains the English-language video with a maximum number of 376,338 views. The Arabian and Spanish videos have high rates with the relevant numbers of 69,512 and 13,887 views.
Thus, one can argue that the nature of educational videos on YouTube are just beginning and quickly becoming actual and popular, while the English-speaking countries are safe to use these resources to self-education. Online platforms have their advantages, as they can be perceived as more serious, and a “student” as a result can obtain a diploma or certificate. That all depends on the interest and the interests of people, as a self-education has no limits. And the simpler the given information is, the better it is perceived and remembered. And then, in the process of analyzing, the studied material, the new thoughts and ideas can serve as the basis for innovative thinking. That’s why a self-education is an integral part of the human activity, which includes elements of motivation, interest and self-organization and as a result all those give impetus to the person progress and realization in the whole.

Modern businesses require group efforts, cooperation, and an effective communication from employees. At the same time, interactive teaching methods allow each student to express his personal knowledge, and some personal traits.
