Online Course as a Tool to Ensure the Quality of Training Highly Qualified Personnel: Problems and Prospects of Use

Nowadays online education is developing rapidly and gradually replacing the traditional format of education. This is due to a number of fundamental advantages of online courses: a geographic accessibility, a convenient training format, and low cost. These advantages allow enterprises to train their specialists at the best universities educational programs without interruption of production process, in the convenient time and place, and also save money for such training. At the same time, statistics show that even on the leading online education platforms, the number of students who successfully complete their online courses is extremely small. This is due to a number of shortcomings and limitations of online learning. The paper presents the results of a study of the Russian student’s online learning experience and attitude. The research results allow us to identify the limitations of online learning and offer special measures to overcome them in order to improve the quality of training of highly qualified personnel.

I. INTRODUCTION
The digitalization of information and communication technologies is rapidly transforming various markets for goods and services. It affects the educational market in all its segments: from preschool to higher. A study conducted in 2017 by a group of analytical and research companies (East-West Digital News, Public Opinion Fund, Netology Group, Internet Initiatives Development Fund, VB Profiles, comScore, etc.) showed that the Russian market of online education and educational technologies has serious prospects for development. So, the researchers expected a significant increase in the share of the online educational services market on the five-year planning horizon (from 1.1% in 2016 to 2.6% in 2021) and more than double market growth in absolute figures (from 20.7 billion rubles in 2016 to 53.3 billion rubles in 2021) [1].
According to researchers, the field of higher education is one of the leading in terms of digitalization. Nowadays it is in third place in terms of online programs penetration (1.8%) after additional school (2.7%) and additional professional education (6.7%). A significant increase in the online segment is also expected in the field of higher education on the fiveyear horizon (to 4.4% by 2021) which means the huge sales increase in this segment. Representation of university courses on an online platform has serious advantages. Firstly, it contributes to a significant geographical expansion of the target audience of the university, providing the opportunity to get access to the educational product for students from the most remote ends Russia and the world. Secondly, the online platform provides the 24x7 availability of the educational product for the target audience. These advantages lead to an increase in the university's audience, and also in students' loyalty, as well as the popularity and university's brand reputation development in the educational services market.

II. STATEMENT
The highlighted benefits are also relevant for students. Online courses provide an opportunity for students from remote regions to study the best educational programs of the best professors from the best universities, independently determining the mode of study. In addition, the universities' online courses provide students an opportunity to receive not only the necessary knowledge and skills, but also a certificate of attendance at a leading university, which is highly rated by potential employers [4,5]. However, at the same time, as practice shows, online courses have a number of significant drawbacks. Online education is not interactive; it does not take into account the level of education and the individual characteristics of the student's perception. The format of online education imposes serious restrictions on the duration and the amount of information provided, i.e. the information content of the educational course is reduced. In addition, the online learning format requires the student to be highly motivated, self-discipline, ambition and good time management skills. However some students do not have the listed qualities. Therefore they cannot complete the online course and pass the final exam successfully. In this regard, the student's results and learning outcomes of online courses are generally lower than for traditional ones.

III. RESEARCH RESULTS AND DISCUSSION
The subject of our research is the study of the attitude of Russian students to online courses. Having studied their experience of online learning, we were able to identify both its positive and negative sides. We interviewed 256 people, of which 27% were men and 73% were women (Fig. 1). At the same time, 79% of the respondents belonged to the age cohort from 18 to 35 years old (Fig. 2). 66% of the respondents had online learning experience, 34% did not have such an experience (Fig. 3). In the group of respondents who had experience of online learning, 81% reacted to innovation positively, 16% neutrally and 3% negatively (Fig. 4).  In the group of respondents who did not have online learning experience, 70% of respondents expressed a positive attitude to innovation, 17%neutral, and 13%negative (Fig. 5). The criteria for choosing an online course (based on a survey of respondents who had experience of online learning) are presented in Fig. 6. The main ones were the quality of the content (its usefulness and interest), the cost of training, as well as feedback from students who had already attended this course.
The requirements of the university or employer, the certificate recognition, the fame of professors and the innovative format of learning played a much smaller role in the consumer choice of online courses.
It is important to note that the majority of respondents metioned certain difficulties in the process of online learning (Fig. 7). For instance about half of the respondents with online learning experience (49%) noted the difficulty in concentrating on the subject of study due to the lack of teacher control; approximately the same number (47%) of respondents noted technical problems that arose during learning. Also important negative factors were the lack of personal contact with the teacher, the lack of the ability to ask questions (42%), and the lack of an individual approach (36%). In addition, respondents noted low online learning outcomes (28%) and internet dependence (26%). Only four people replied that they had no difficulties in completing the online courses. Despite the difficulties described above, the majority of respondents (64%) were satisfied with online learning (Fig. 8). Among respondents who did not have online learning experience, almost all respondents (97%) knew about such educational format (Fig. 9). This is not surprising, since the online education market is now not only rapidly developing, but its development is actively discussed in the media and social networks, occupying a significant part of the information space.
Thus, despite the knowledge of the existence of online learning, many respondents refuse to use it. Why is this happening? In order to answer this question, we asked respondents to explain the reasons for not using online courses. The results of the responses are presented in Fig. 10. It turned out that 23% of respondents do not see the need to use online training; 21% were unable to find suitable courses; 18% generally do not trust online learning, 12% prefer the traditional offline format. Finally, 6% of respondents simply have difficulties in using the modern educational technologies. The results of our study showed that in general the modern online learning format satisfies Russian students. However, it has certain disadvantages that must be taken into account when developing this educational format. The main ones include the difficulty of self-organization of work, technical problems and lack of contact with the teacher. The presence of these problems leads to the three key problems. Firstly, many potential users refuse online courses at all. Secondly, a significant part of stidents who started an online course quits studying on the different stages of learning process. Thirdly, the satisfaction of students who successfully completed an online course is reduced.
To overcome these negative consequences, it is possible to offer a set of recommendations. Among the main recommendations for developing online courses and increasing their attractiveness for the target audience, our respondents expressed ideas about introducing the practice of individual work with the teacher (for example, the ability to ask questions and get detailed teachers' explanations on them; receive teachers' feedback on the results of the course assignments; teachers' explanations of students mistakes made in solving problems and cases with giving right solutions, etc.). The second important point is the clarity of the instructions for working with the online course. This will help students evaluate the amount of work in advance and understand the course requirements. And finally, the third is the motivational part. The online course must include a particular explanation on what specific knowledge and skills can be received by student trougth passing each part of the course, and how student can to apply it in the future.
Thus, in addition to high geographical and time accessibility, high-quality and interesting content, well-known teachers and a convenient study format, the online course should include the individual interaction with students, offer effective tools for their motivation, and develop clear instructions for users.
