Abstract
Current literature does not provide exhaustive information about leadership as part of teaching and learning. The distance learning format creates a platform for developing leadership skills. However, this form of education is often confused with the denial of the importance of education and the ideas of “unschooling”, which leads to a negative attitude in society towards extramural forms of study. This study demonstrates the value of distance learning in the education system, and describes specific leadership skills that can be improved through distance learning. The study disproves unconfirmed judgments and clichés about detachment, loneliness, and the degradation of communicative competencies among distance learning students. The study as well outlines the impact of extramural forms of study on the development of inclusiveness and tolerance for self-expression in educational classes. Thus, it has been proven that distance learning has a positive influence on skills development.

Across the world, distance education is developing through the establishment of open universities that use the latest computer technologies (Chakraborty and Chakraborty, 2004; Crawford, 2012; Rego et al., 2007). In modern Europe, there is a great deal of educational institutions offering distance-learning programs. The interest in technology-based education programs involving satellite services and networking has increased significantly (Becker et al., 2002; Bennet et al., 2003; Benjamin and Flynn, 2006; Plas and Lewis, 2000).
Distance learning is a new promising technology designed to engage students in independent learning. Such a system uses electronic technologies for communication between students and teachers separated in space (location), time, or both (Razik and Swanson, 2010; Silverthorne, 2001).
In the early 1930s, Kurt Lewin studied the influence of group forces on the behavior of an individual, and drew his attention to leadership. It turned out that a group can have a significant controlling effect on a leader, overcoming his/her impact with time (Bush and Glover, 2004).
In education management, a leader serves as a mentor who influences students at the administrative level. Sometimes, there can be a team of multiple leaders, whose role is to find better ways of teaching (including distance teaching).
Leadership refers to managerial decision-making process (Bryk et al., 2010). Management is a process of making right decisions, even though they may not satisfy the majority of participants engaged in learning (Judge et al., 2002).
A good leader encourages his/her colleagues to solve a common task, contributes to their progress on unlocking the inner power, and makes them feel as comfortable with their work as if they are co-owning the company. The interest of employees in dedication, a sense of responsibility and pride in their organization are crucial to effective performance of this organization (Day, 2000).
Management and leadership operate at different levels. While the first finds the best possible ways of solving problems, the second determines what exactly needs to be done. Most leadership theories view leadership through the lens of individual’s experience, abilities and potential (Garrison, 2011).
Researchers usually define leadership according to the goals of their studies. Thus, there are as many definitions of leadership as there are researchers of this matter. Leadership is a process in which a person interacts with others in order to reach a specific goal (Giessner and Schubert, 2007).
This study explores the potential for creating an optimal environment for distance learning using the theory of leadership. In this regard, the survey has been conducted with the aim to identify specific skills of a leader. Thus, it is proven that distance learning has a positive influence on the development of skills.
Theoretical framework
Psychological studies distinguish various styles of leadership that come from different concepts. The most famous concepts of leadership are as follows.
Trait theory of (charismatic) leadership
A leader possesses unique personality traits. There are many different lists of these traits and none of them is unified and complete. The theory of charismatic leadership states that a leader is born with innate qualities of a leader like charisma, which in Greek means “a divine gift”. A charismatic leader enjoys absolute confidence in the group, encourages others to follow him/her (Morrison, 2010).
Situational theory of leadership
This theory accepts the trait theory and assumes a change in leadership styles from situation to situation. At this point, challenges in communication in different situations bring to the foreground the individuals who dominate others in at least one quality. With a discarded statement about the inheritance of traits, this theory expresses a belief that a particular situation stimulates and ensures full manifestation of specific leadership features. A situational leader leads in one situation and does not demonstrate leadership qualities in another. Yet, he/she is labeled a leader anyway (Salihu, 2019). If a person has proven him/herself as a situational leader in one situation, then he/she might be recognized as a leader in a similar situation. Being flexible allows a person to effectively demonstrate leadership qualities in the context of turbulence (i.e., educational, commercial, political).
Behavioral approach to leadership
A leader behaves in one of several ways. The effectiveness of a chosen style of behavior depends on a specific situation: when the situation changes, so does the style (Yukl et al., 2019). This approach analyses and classifies various leadership styles. However, this approach is less developed in comparison to situational theory.
Relational leadership theory
A leader focuses on togetherness and builds ties between group members. This theory embraces personal traits structure of a leader, the lasting period of group’s existence, etc. It defines leadership as a result of joint activities, when each member of the group adds to the solution (Wong et al., 2019). Thus, common tasks and goals, as well as common setting and other factors, are predictors of leadership. Most of domestic studies on leadership gather around this theory. A person tends to organize his/her knowledge about the world via schemas (stereotypes) (Kaplan and Kaiser, 2003). When processing social information, three types of schemes are used: personal, situational, and role-based. The latter may be related to occupations, positions in a group. The scheme allows recognition of a stimulus and behavior prediction. This is how leadership stereotypes are born. In order to overcome inconsistencies that arise between stereotype-based expectations and actual behavior of another person, the individual makes causal attribution, or ignores those inconsistencies, or aligns roles, or labels a person as deviant (Nicholson and Kurucz, 2019).
Methods
Ethical approval
All participants in the study conformed to the principles outlined in the Declaration of Helsinki and have been performed with the permission, released by the responsible Ethic’s Committee of Kazan Federal University. All the patients were informed about the purposes of the study and have signed their consent to participate in the study, and to collection and processing of personal data. This article does not contain any studies with animals performed by any of the authors.
The study is designed on the basis of a research goal. The goal is to find out whether leadership can be developed during distance education. Thus, hypotheses of Jacob (2015), Wowk et al. (2017), and Kromydas (2017) about leadership in education have been confirmed. For this, models and characteristics associated with leadership and leaders have been identified, then they have been correlated with the distance learning environment to determine the presence or absence of contradictions. Thus, thanks to “proof by contradiction”, the possibility of leadership development during distance learning has been proven.
This study uses such methods as survey, testing, quantitative and qualitative analysis, statistical data processing. The survey comprises a Leadership Stereotypes Questionnaire. The respondents are 800 students of both sexes, aged 18–20, from two universities in Kazan. Twenty Statements Test (TST) is used, which is adapted according to Locatelli and West (1996) and Leadership Stereotypes Questionnaire in Rean’s modification (Eacott, 2015; Farkas and Wetlaufer, 1996; Rosete and Ciarrochi, 2005), allowing to determine the basic models of gaining leadership.
Data for processing is t-distributed. Correlation and cluster analyses are additionally involved for quantitatively reasoned reliability of data processing.
A Leadership Stereotypes Questionnaire includes two blocks of questions, which have been processed by cluster analysis of STATISTICA program:
-
Block 1. Questions about leadership stereotypes, leader’s role in a group, (fe)male, and (in)formal leadership.
-
Block 2. Questions about one’s dependence upon the opinion of others, about factors influencing interpersonal perception of leadership.
The combination of the methods of subjective (through the experience of respondents) and objective (machine calculation of clusters) assessment allowed the study to gain greater argumentation regarding the manifestations of leadership during training. Induction methods are also used to identify the specifics of the direct implementation of the distance learning format. The synthesis method is used to determine how distance learning approaches impact the educational institution in society. System-based institutional analysis is used in assessing the place of distance learning in the education system and identifying the influence connections within this system.
Respondents familiarized with the research procedure and those responses which format did not correspond to the given research procedure were excluded from further analysis. Overall, 18 responses were excluded. The survey was standardized and questionnaires were completed in a favorable psycho-emotional setting, which contributed to good verification practice. Apart from this, the survey included control questions that were compared with the relevant questions. Information about respondents was preliminary analyzed for higher sample homogeneity.
Results
The process of informatization of society directly affects the education system. There are such valuable aspects as freedom of a person, protection of his/her rights to self-expression, and choice of professional activity. These aspects stimulate the emergence of tendencies to receive educational services distantly by people of different age. Distance learning eliminates the necessity for students to be physically present in the same classroom with the teacher. Information technology makes educational process more accessible to the listener, regardless of his/her geographical location. The asynchrony principle of classes creates convenience and, as a result, satisfaction with the educational process from both the student and the teacher (Bradbury, 2019). Since the creation of the lesson, a period of learning, the completion of tasks and assessment are separated in time. Thus, the student is more focused and motivated, since he/she conducts the lesson in a convenient place and time slot. Freedom of choice and the simultaneous commitment to learn a lesson, provoke the student to lead a more disciplined lifestyle, keep a schedule of classes, use time management tools in everyday life.
It is important to understand that the principles of extramural studies (home education for children or distance learning for adults) are not about the lack of control over the process of learning (which is typical for “unschooling”) (Vasconcelos, 2017). Studies imply permanent tracking of student success through the electronic system, access to which is possible from any electronic device. The student does not skip classes while at home, but uses his/her time more rationally in order to study the basic program and concentrate on the scientific areas of his/her interest. In such conditions, the extramural student receives more in-depth knowledge than his/her intramural peers, since intramural education always averages the level of educational information offered to students. Intramural education as well cannot be adapted to the quality of training of each individual student.
Moreover, a visit to an educational institution takes a lot of time (6–10 h a day, 5–6 days a week, from 6–7 to 17–18 years), practically depriving children of their childhood. This is especially true for younger students, for whom the main method of knowing the world is figurative, and not logically rational (Bruns et al., 2011). Daily physical presence in an educational institution limits the child’s independence, gives him/her an extremely limited right to choose his/her free time from school (for example, the obligation to do homework). A child is also limited while choosing a social environment, and a way of interacting with the outside world (Kosse et al., 2020). Therefore, children can feel the lack of independency in his/her judgments and actions.
Thus, a new institution appears in society, which can be called a “virtual school”, where a school means a system of receiving both general education and higher education. All processes and relationships in such a system are completely remote and virtualized. The physical distance between teachers and students creates the effect of reducing internal stress and thus communication skills on both sides can be improved. In such communication, there are less stereotype, social clichés and tangible subordination. As subordination often interferes with the learning process and deprives the pedagogical process of trust (Giessner and Schubert, 2007).
The fact that a student is not physically present amongst his/her team members does not imply his/her loneliness and lack of experience of group interaction. A methodologically well-organized process of distance learning injects a student into various teams on a permanent basis. For example, up to 20 students can attend an online lesson, the teacher sees each of them, and the students see each other, socialization is not lost but maintained by student chats. During such lesson, students work directly with each other on some tasks. This practice allows student to test different communication strategies and to be at the same level of understanding with peers (Simpson, 2018). The student develops leadership skills through communication with new partners.
A survey among students confirms that the leader has identification indicators. To the majority of students, the way other students see them is important. Factors influencing the way one or another member of the group sees someone as a leader are reported to be behavior (80%), open mind and intelligence (50%), appearance (i.e. physical attractiveness, style, etc.) (15%).
For respondents, a leader possess a range of diverse traits (Fig. 1) that compose an image of an “ideal” leader. In many respects, such as image could grow from a “native” culture and educational environment which these respondents share.
After cluster analysis of questionnaires, the following groups for “indicating” leaders are identified:
-
1.
Absolute leaders—who achieve and maintain the status of both a formal and informal leader;
-
2.
Instrumental leaders—who are selected as leaders only for their task-oriented attitude;
-
3.
Expressive leaders—who are selected as leaders for their ability to promote emotional strength.
The achieved results are consistent with the findings of Ossiannilsson (2018), Diamond (2008), and Russell (2013). Thus, there are relatively well-established leadership acquisition models that are relevant for distance learning as well.
Twenty Statements Test (TST) has been adapted to the research task according to the recommendations of Locatelli and West (1996) and contained an interpretation of the question “What am I, if I am a leader?”, which made it possible to more accurately determine the characteristics of a leader in the perception of respondents.
The TST descriptors have been set out in statements about personal attributes of a leader and associated role models:
-
1.
Leadership role characteristics or socio-demographic characteristics of a leader;
-
2.
Personal leader qualities (smart, kind, etc.);
-
3.
Аppearance (physical appearance and fashion style);
-
4.
Вehavioral and communication characteristics.
TST findings show that testing has revealed a high uniformity of responses among respondents (with a standard sampling error of 2.2%) and the majority of respondents (80.5%) primarily pay respect to personal traits. The latter are followed by communication behavior, appearance, and leadership role characteristics. Regardless of gender, personal traits are distinguished as responsibility, kindness, intelligence, honesty, strong character, distinction, and willpower. It is important to note that these characteristics correspond to those forming an image of a leader in a survey. That is, the subjective (based solely on personal experience) assessment of respondents coincides with the machine calculation of possible leadership models. This could serve evidence both on a well-organized research procedure and homogeneous sample and on the fact that the questionnaire design failed to go beyond the cultural template, thereby generating a cultural bias.
As the study shows, a disability or a serious illness or an unremarkable appearance cannot prevent a student from gaining leadership skills. Thus, the distance learning format creates the conditions for inclusion, as well as directly increases the opportunities for gaining leadership, since such a training format according to Nworie (2012) reduces the pressure of society on the formation of personality. Students of distance learning programs gain leadership skills, use them in life and thereby enhance their life position and motivation to learn (since learning is always an individual’s desire to improve him/herself). Students of distance learning programs become more resistant to learning difficulties. The said, in accordance with Grooms (2000), can be regarded as one of the signs of leadership that is formed during study. Thus, distance learners are less likely to drop out compared to intramural students, which generally indicates a greater focus of distance learning process on the quality of knowledge and the involvement of students in the process.
Discussion
Distance learning systems stimulate the leadership and effective work not only of students, but also of teachers, methodologists, and management bodies of educational institutions.
This is manifested in the following:
-
reducing the cost of training for both students and teachers (as there is no need to rent premises, the money is not spent on trips to the place of study, etc.);
-
reduction of time needed to get ready and travel;
-
the participant can independently plan the time, place and duration of classes;
-
conducting education for a large number of people at the same time;
-
improving the quality of education through the use of modern tools, voluminous electronic libraries, etc.
-
creation of a unified educational environment (which is especially important for corporate training) (Waters and Marzano, 2006).
In addition, in contrast to the standardized, averaged approaches of the school, the distance learning format creates a competitive advantage. As distance learning actively uses fully interactive and hybrid or mixed courses that offer flexible learning formats for students of all ages through individual learning. The latter adapts to their needs and expectations. Such an approach is a reliable foundation for the development of the leader, in the understanding of society—whether a woman or a man (Becker et al., 2002).
In various fields of activity, men and women demonstrate leadership qualities differently, depending on the way they have acquired these qualities (whether they are nurtured, gained throughout life, or learned) (Bush, 2007, 2010; Bush and Glover, 2004; Rego et al., 2007). Some scientists label female leadership as democratic and flexible in style. They believe that empathy, sociability, adaptability, and lower aggression are traits that are more found in women (Waters and Marzano, 2006). Female leaders have a number of common characteristics—competence, pomposity, high-performance capability and creativity (Boling et al., 2012; Heck and Hallinger, 2005; Mitgang, 2012). They have high self-esteem, a clear idea of goals, self-awareness, a “cool head”, vigor, independence and no credit for restrictions. They are often expressive leaders, oriented towards interpersonal relations. Female leaders dominate in small groups, are more open-minded, expansive, and interact better with staff. Theories explaining reasons for gender disproportion in leadership can be divided into three categories: theories about gender, about leadership, and those considering both factors. Most studies devoted to gender in leadership encompass six issues surrounding the relationship between leadership and gender:
-
1.
The number of men and women in leadership roles;
-
2.
Leadership style and behavior;
-
3.
Leadership effectiveness;
-
4.
Leadership and gender composition of a group;
-
5.
Strive for leadership;
-
6.
Gender identity of leaders (Eacott, 2015; Elfenbein and Ambady, 2002; Mendels and Mitgang, 2013).
Wherein, the main thing is that the effectiveness of an educational organization depends on leader’s ability to manage formal and informal communications, and to create a unified communicative system, the access to reliable and complete information. Competences for solving this aspect are highly efficiently formed through distance education, which explains its high relevance in the system of educational institutions in society.
Conclusion
Within a group, student becomes a leader if he/she possesses strong personal traits and fits with a leader prototype, which has formed in the minds of group members. However, the foundation of leadership behavior is formed before the introduction of a person into the team. An education in a distance format can be an effective tool in this regard.
According to the study, the majority of students, regardless of gender, believe that being a leader is something both sexes can do.
Factors influencing the way one or another member of the group sees someone as a leader are the organizational structure (formal or informal) of a group and the dimension (emotional or instrumental) of intragroup relations.
The findings show that boundaries of leadership stereotyping become blurred. These results may be used to design online courses for distance learning in universities with regard to differences in training requests and predisposition to leadership.
Leadership has become an important feature of the modern personality, which seeks social success and can achieve it. The educational world today is tightly connected with information technology, which allows many students to access information and create new skills, regardless of location. Distance education becomes an effective way of gaining leadership without the influence of social stereotypes, clichés and other barriers.
