Previously published in Russian in the journal Pedagogy and Education.

Currently, digitalization has covered all spheres of human activity, including education. As a result, digital learning technologies, which are used both remotely and in traditional face-to-face learning, have become an integral part of the educational process. The availability of digital tools has made it possible to conduct real distance learning, which has many advantages compared to traditional offline learning. The main advantage of distance learning is the possibility of obtaining a high-level education without leaving for another city and without leaving work, which allows a huge number of people to gain additional education, take advanced training courses, and acquire a new profession in the process of online training. The undoubted advantages of the distance learning format—time flexibility and the ability to take classes conveniently and from anywhere in the world—have led to the widespread introduction of various distance learning courses, including university courses, into the education system. But, despite the advantages, the distance learning format also has disadvantages, which may affect the result of training when receiving a bachelor's or master's degree at a university in a distance format. A deep comparative analysis of various teaching methods is required: traditional, which involves personal communication between students and a teacher in the classroom but using the latest digital technologies, and remote, which is conducted online. It should be clarified that, at present, digitalization can be considered an integral element of both traditional and distance learning. Therefore, when comparing the two forms of education, it is necessary to separate the impact of the use of digital technologies from the influence of various forms of educational process organization: the traditional form of education with personal contact with the teacher and fellow students or the remote form without personal contact. However, it should be remembered that digitalization and the use of electronic content in distance learning covers all aspects of the learning system ^{[1, p. 117]}, which does not happen in traditional learning. At the same time, both distance learning and traditional face-to-face learning are transforming educational relationships that are fully or partially transferred to the virtual space using new forms and opportunities in these relationships ^{[2, p.1160]}.

The COVID-19 pandemic was not only a powerful impetus for the use of distance technologies at all levels of education [3. p. 115] but also allowed some quantitative assessments to be made when comparing the training results in the traditional and distance formats. In general, the use of distance learning during the pandemic showed not only the effectiveness of using online technologies in education but also identified several problems that need to be solved when using distance learning. The issues of using distance learning technologies in teaching students of higher educational institutions include the following [3–7]:

– lack of full feedback during training,

– lack of social contacts and group interaction during training,

– reduced motivation of students during online learning,

– the absence of such a decisive element in the learning process as imitation,

– technical errors that occur when using various distance learning systems,

– technical problems related to the operation of equipment,

– problems of digital inequality related to the fact that different students with different educational levels demonstrate different effectiveness in extracting information from digital sources and its practical application,

– lack of students' formed skills in organizing their own educational activities within the framework of flexible management of their time,

– insufficient psychological readiness for independent learning.

The accumulated data on the effectiveness and features of online learning during the fairly widespread use of distance learning technologies require a detailed analysis of the distance and the usual full-time learning method. Therefore, this work aims to compare the features of the application of the traditional teaching and distance education method in the conditions of rapid digitalization of all spheres of human activity.

Materials and methods of research

The objectives of the conducted research were: a) the study of the influence of interpersonal communications on the process and outcomes of higher education, b) the study of the influence of various digital and traditional learning technologies on student motivation and learning outcomes, c) the choice of the most effective technologies to ensure the desired result from educational activities. At the same time, the problems that arise for teaching staff during the transition to distance learning, associated with an increase in the teacher's word load and the need to master new technologies and new teaching methods, were not considered.

By the tasks set, a comparative analysis of various learning methods using distance learning technologies was used as a research method based on the synthesis of a large amount of data that was published after the start of the COVID-19 pandemic [8–13]. The paper uses the results of studies that primarily use the materials of a mixed questionnaire (conducted in the form of a survey with the distribution of material in traditional form or as an electronic survey) ^{[4, 8, 14, 15]}. The results of the students' academic performance analysis, combined with a survey ^{[5, 9]}, were also used. It should be noted that, despite the large number of studies on comparing various forms of education in individual educational institutions, only some works summarize the results of the conducted research. This is because the specifics of the training organization and assessment of knowledge for students of various specialties can vary greatly, which makes it difficult to quantify the influence of various factors on the nature of the formation of students' preferences, their satisfaction, and the result of mastering the educational program.

Research results and their discussion

In accordance with the purpose of this study, it is necessary to analyze both subjective assessments of students participating in the educational process and objective indicators that consider student academic performance. First, let's look at how students evaluate various elements of the educational process conducted in traditional or electronic form. As a result of a large-scale study of the academic activities of a large number of students in the Ural region conducted in 2020, it was shown that, at present, the form of realizing information available to students plays a significant role ^[8]. The content presented to students on electronic media was evaluated by students as less important than the content presented in traditional form (see Fig.1, the source of the questionnaire ^{[8, p. 161]}). Thus, the information received by students in electronic or traditional form from departments, specialized offices, and libraries was evaluated by students in importance in approximately the same way (Fig. 1). However, the information received in direct contact with the teacher and fellow students in traditional form during lectures, practical, laboratory classes, turns out to be more than two times more important than information via electronic media.

Other studies confirm the conclusions obtained above. Thus, a study covering students of 30 universities in the Russian Federation from the Central, Volga, Ural, Far Eastern, Southern, and Siberian districts showed that students easily master distance learning technologies, perceiving it as traditional learning transferred to digital format ^[3]. As a result of regression analysis, the possibility of social interaction and integration had the greatest influence on forming positive experiences among students during their studies. Students involved in interaction with teachers and other students experience greater satisfaction and positive experiences, leading to greater involvement in learning and creating greater responsibility.

Similar conclusions can be drawn from an experimental study that examined students' assessment of lectures delivered by unfamiliar teachers in a traditional format in the classroom and the same lectures shown to students in a video ^{[16, p.135]}. As can be seen from Figure 2, the teachers' video lectures received lower student ratings in all parameters. The most significant difference in grades was obtained by the criterion of "interest," which is explained by the influence of the teacher's personality during the classroom lecture. However, a significant difference was demonstrated by the amount of information learned (the last column in Fig. 2). After the classroom lecture, students learned 1.4 times more information than after the video recording of the same lecture. This has been demonstrated in many studies confirming the following: all things being equal, the most informative and valuable are those lectures during which the lecturer establishes live contact with the audience, and the audience should be able to see the speaker's facial expressions, gestures, and emotional reaction ^{[14, p. 101]}.

Let's consider objective criteria for the effectiveness of various teaching methods, including the average score during certification and the number of students who successfully passed the subject. A study conducted at Orenburg State University compared the average score obtained by students during a session with traditional training (during the 2019/2020 academic year) and during distance learning (2020/2021 academic year) ^{[17, p.130]}. The average score obtained by students in exams did not change much during the transition from traditional to distance learning for both technical and humanities specialties. However, the proportion of students who successfully passed the session decreased in some groups (see Figure 3 for technical and Figure 4 for humanities). If for technical specialties, the share of successful students who passed the course both increased and significantly decreased (see Fig. 3, group 18STR/AD), then for humanities specialties, this share decreased in most groups (Fig.4). However, according to the students themselves, technical specialties cause great difficulties compared to humanities with distance learning ^{[4, p. 111]}.

The studies reviewed were conducted for distance learning during the 2020/2021 pandemic; therefore, comparing traditional and distance learning results may only partially reflect the real picture, as for objective reasons, online and traditional exams were conducted in different conditions. However, when conducting certification in a standardized format, the differences between various types of training are significant, as shown in ^[9]. Students studying simultaneously with the same teacher in 2019 at the University of Eastern California assessed their professional skills before and after learning during the semester by answering questionnaire questions numbered in Figure 5 as Q1.1, Q1.2, Q1.3, Q1.4, and Q2. As shown in Fig. 5, students who chose traditional education evaluated their professional competencies significantly higher than students who chose distance learning. After completing their training during the semester, these grades, as expected, increased. However, the gap between the two forms of education remained: after studying in the traditional classroom, students gained more professional skills and abilities.

Here are the results of another comparison of the results of the final attestation of students obtained by the same students during the exam in mathematical analysis conducted in the traditional form in the winter session of the 2019/2020 academic year and during the final control work in remote form during the pandemic in the summer session of the 2019/2020 academic year ^[5]. The average score received by students for the exam in the traditional form, reduced to a five-point scale, is 2.0, while the average score of the same students for the summer session during the remote form is 4.2. Presumably, students received higher scores for remote work as a result of the fact that they could, despite the control, use the Internet. Therefore, for an adequate assessment and comparison of various forms of training, it is necessary to provide a standardized procedure for conducting final certification in the traditional and distance forms.

It should be noted that conducting exams remotely requires significant processing of exam assignments to exclude the possibility of simply using Internet calculators and an online bank of answers to questions on various topics. On the one hand, the commonality of assessment criteria should be maintained when conducting exams in any form while preserving the basic didactic principles of drawing up examination tasks, including a variety of functions to cover material on all topics, balance in terms of complexity, uniformity of tasks in individual sections ^[15].

On the other hand, when conducting a remote exam to prevent students from using Internet resources, careful work is required on the selection of both the questions and buildings them, as well as in formulating them, which should not make it possible to find a quick answer using quick copying but should make the studied material comprehensible. To do this, in the online exam, in addition to questions in the selection of answers, you can use the input of intermediate results of solving the problem in various templates and the input of step-by-step problem-solving. However, such preparation of tasks requires a lot of the teacher's time, and due to the high role of social interaction of students who collect information about all the tasks that exist, it is necessary to revise them every semester and show a creative approach ^{[15, p. 26]}. At the same time, the teacher must constantly improve both pedagogically and their level of computer technology proficiency.

In this regard, it should be noted that a modern teacher must possess high-level digital skills like searching and evaluating information on the Internet, independently creating educational materials and multimedia content, using existing educational resources, and creating virtual platforms for their student groups both based on the distance learning system used and on social networks, creating and distributing their digital portfolio, choosing modern methods, including mixed and mobile learning ^[18]. Mixed learning is a set of techniques and strategies that include three mandatory components: classroom, distance learning with a teacher, and mandatory independent work that a teacher must organize ^[19]. Blended learning has great potential for further development and can become one of the most common forms of learning ^{[20, p. 97]}. Mixed learning technologies are currently undergoing a stage of formation and simultaneous rapid development, which makes it difficult to timely assess their various aspects from the point of view of a scientific approach. However, from the typology of the twelve models of blended learning presented in ^{[19, p.56]}, it is possible to identify models with high potential for further development. This is a mixed individual curriculum where the student chooses the number of subjects they need along with the form of study for each subject; a mixed academic subject, when various sections of the subject, as well as various stages of mastering (learning new material, consolidation, control, practical application), are studied by contact or remotely; online support with the organization of collective webinars and answers to questions; a mixed study that can be applied to undergraduates. Similar models or elements of blended learning are already being used in the training of students, which shows their undoubted attractiveness and prospects for improvement.

Conclusions

This paper compares the results of traditional and distance learning based on the analysis of quantitative and qualitative assessments of learning outcomes obtained during the training of students of higher educational institutions from various specialties. The following can be noted as a result of analyzing the learning outcomes obtained using various forms of learning. Currently, the highest results are achieved when using traditional and mixed training. The traditional approach, carried out in the presence of direct contact between the teacher and students, provides a strong motivation to study due to direct interaction with the teaching staff and a comfortable perception of information both during lectures and during practical classes. The results of mastering theoretical information and practical skills when using traditional teaching are higher than when using distance learning, and students' subjective assessments of the convenience and comfort of learning are also higher for traditional teaching methods. At the same time, the traditional approach uses all modern digital technologies to provide better accessibility and visibility of the information received. Blended learning, which is undergoing rapid development at present, can be considered an evolution of traditional learning in the era of digitalization when some stages of learning can be more effectively organized in digital form and a distance format. Such stages and elements of training include the current control of knowledge, the development of practical skills in solving standard tasks, and the initial study of new material. At the same time, students' direct contact with the teacher and study group members is wholly preserved. Distance learning at this stage makes it possible to make education accessible to large groups of the population, which is one of the main advantages of this format. However, the results of mastering the educational material with remote learning show its lower effectiveness than the traditional and mixed approach.
