2.2. Teacher Leadership
Teacher leadership plays an important role in teachers’ continuous professional development and the long-term improvement of educational outcomes [
4,
5,
13]. Leading teachers are coordinators, coaches, specialists, head teachers, department heads, and mentors [
14]. In the traditional sense of leadership, teachers have two options for work responsibilities: one is to only teach and work until retirement or to leave teaching and take a leadership position [
2]. According to the traditional understanding of leadership, it was understood that leadership is related to the position of a leader. Teacher leadership can be defined as formal and informal. Formal leadership refers to those who hold formal positions and titles as members of a school’s management team; informal leadership refers to a person’s behavior and skill-based leadership ability, which is successfully encouraged by others.
In their research, Silva, Gimbert, and Nolan [
15] defined the evolution of formal teacher leadership into three stages: in the first stage, schools focused on supervising teachers and appointed department heads and master teachers. Their managerial role was seen as passive in the role of teachers. In the second stage, the teacher leaders were promoted to head of academic training and head of the program. Although some strengths emerged, these roles distinguished teacher leaders from their colleagues and reduced their influence on program improvement. In the third stage, the teacher prefers to lead the teacher’s professional development activities. This is because teachers actively participate in solving problems at the university level, such as improving the content of courses and programs without being told by anyone, and then give their opinions and votes on the university’s mission, vision, strategy, relevant rules, and regulations.
Based on the three stages of teacher leadership development, the official leadership of teachers is not very effective. Although this conclusion was drawn at the secondary school level, we believe it reflects a similar trend in the development of the educational system as observed in the evolution of teacher leadership across all levels of educational institutions. We particularly emphasize the significance of individual teacher characteristics in strengthening leadership among university teachers.
There was a time when teachers’ leadership was understood as related to their position, authority, and official duties. In other words, the teacher’s leadership was evaluated in terms of position and authority. However, according to Barbara B. Kevin, every teacher is a leader, and informal teacher leadership is born from the ranks of teachers who demonstrate high levels of leadership and provide lessons for formal leaders to improve their leadership practices. Informal teacher leadership is not a formally assigned role but a process created informally through specific actions [
16].
Because we want to emphasize that every teacher needs to be a leader in the course, class, school, and community, teachers must take the lead in many areas. For example, new trends such as digital technology and the introduction of blended learning teaching methods have recently emerged, so new roles and responsibilities may continue to increase their leadership. Therefore, teacher leadership highly depends on the teacher’s behavior and skills. In particular, the teacher’s personal beliefs, values, ethics, character, and positive attitude reach the students through the teacher’s leadership. Leadership is a dynamic process that involves influencing individuals and groups to direct their actions towards achieving common goals. In this context, a leader is an authority figure who can motivate, guide, and inspire others, getting them to work together to achieve results, as teachers do with the students [
17]. Northouse indicates that: “(a) Leadership is a process, (b) leadership involves influencing others, (c) leadership happens within the group, (d) leadership involves goal attainment”. Therefore, researchers define “leadership” as a process of influencing others to achieve their goals by leading with their beliefs, values, ethics, character, knowledge, and abilities, and every teacher should have it. In recent years, there was a significant shift in how educational leadership is conceived, especially within schools. Educational Leadership and Management (EDLM) researchers have raised an important thought: school leadership should not be seen only as a role involving the school leader or a top figure but as a distributed process involving the entire school staff, including teachers [
4,
18,
19].
Teacher leadership in education affects the university’s reputation, teacher performance, student success, and social development. Personal teacher leadership has a greater impact on program outcomes, learning quality, and student satisfaction. Teacher leadership is an important component of student success, and teachers must be included in the decisions that affect students [
20]. Teacher leadership aims to promote student learning achievement, including developing the school organization altogether [
3].
Wenner and Campbell [
3] argued that teacher leaders’ roles transcend the classroom walls in working towards change and school improvement. Leadership opportunities for teachers are critical to addressing and solving the problem of recognizing and valuing the talents of those teachers who contribute significantly to student learning, collaboration among colleagues, and the overall improvement of the school system. Creating leadership spaces for teachers not only promotes instructional innovation but also reinforces a sense of responsibility and belonging to the entire school community [
21,
22].
2.3. Teacher Leadership in Higher Education
Analyzing the scientific literature on teachers’ leadership impact in HEIS, it is possible to find different aspects and indications of the teacher leadership role and its emergences, as teacher leadership and the HEI educational process [
23,
24,
25,
26,
27,
28]; teacher leadership and personal skills and perceived roles [
23,
27,
28,
29,
30]; leadership styles, and performance [
25,
26,
31,
32,
33]; teacher leadership formation, and barriers [
26,
27,
34]. Speaking about teachers’ leadership and the impact on the HEI process, some researchers are analyzing the role of leadership in research [
23,
24], research about teacher leadership and faculty development [
25,
26,
27], and research about teacher leadership and curriculum development [
28]. In the HEIS environment, teacher leaders often serve as catalysts for change, advocating for pedagogical practices that reflect contemporary educational theories and respond to diverse student demographics. Such dynamics underscore recognizing and cultivating teacher leadership within universities as integral to successful curriculum development and institutional effectiveness. Teacher leaders offer invaluable insights into student learning and engagement complexities [
35,
36]. Faculty collaboration emerges as a pivotal component in successfully reforming university curricula, facilitating a dynamic exchange of ideas that enhances educational outcomes. By fostering sustained collaboration among faculty members, institutions can align strategic priorities, leading to cohesive and innovative curriculum designs that are responsive to the diverse needs of the student body. The collaborative efforts create a supportive infrastructure for curriculum development and ensure that reforms are sustainable, enhancing faculty ownership of the curricular process and enriching the academic experience for all stakeholders involved. Harrison and Killion (2007) [
23] identify several key roles that professor leaders may assume, which include: “resource provider, instructional specialist, curriculum specialist, classroom supporter, learning facilitator, mentor, school leader, data coach, catalyst for change and learner”. In their 2007 work, Harrison and Killion [
23] explored the diverse ways professors demonstrate leadership in educational settings. They emphasize that leadership among professors is not restricted to formal, designated roles but also includes informal leadership that develops through interactions with peers and the academic community. For Ball [
24], leadership in universities “can improve research outcomes, staff enthusiasm, and commitment”.
In his research on other aspects of teacher leadership skills, da Silva Freitas Junior et al. [
27] analyzed which skills are more important for a leader. They found that the skills are confidence, open-mindedness, being an example, influencing, and establishing trust. They also proposed a plan for leadership development.
Similarly, researchers have drawn attention to the leadership role of university faculty, including their dispositions [
29]. University faculty and leadership development have focused on research and outcomes rather than teaching. In some cases, it resulted in teaching deficiencies, as highlighted by Dijk et al. [
37] In recent years, employers have particularly underscored the value of soft skills in the workspace, including leadership skills. This certainly interests us since university faculty could themselves be better at leadership and take their students to development. This emphasis on the value of soft skills in the workplace is enlightening, as it underscores the importance of these skills in the professional development of university faculty and the subsequent impact on student learning and development.
Professional development programs in higher education may concentrate on developing the leadership skills of academic staff, such as leading teams, mentoring colleagues, and designing innovative teaching methods.
2.4. Teacher’s Professional Disposition
A university teacher can be said to be a dual professional. This is because a university teacher not only has a profession such as an engineer, veterinarian, or economist but also learns the professional approach and quality of teaching and carries out teaching work. In addition to professional knowledge and skills, individual teaching skills and abilities continue to change based on learner behavior, attitudes, and needs. Therefore, researchers are paying attention to the study of the personal and professional dispositions of teachers. The reason is that professional dispositions are the values, commitments, and professional ethics that influence behaviors towards students, families, colleagues, and communities that affect student learning, motivation, development, and an individual’s professional growth (NCATE) [
38]. Teacher dispositions, understood as professional virtues, mental and behavioral qualities and habits, are key elements that directly influence teaching effectiveness and the quality of learning. These dispositions are not innate, but develop through experience, professional commitment, continuing education and dialogue with those involved in the educational process (students, families, colleagues and the community) [
39]. Shari et al. [
40] noted that dispositions are “ongoing tendencies that guide intellectual behaviour”.
Furthermore, Misco and Shiveley [
41] suggested that dispositions have three different categorical aims: (a) dispositions as personal virtues, (b) dispositions as educational values, and (c) dispositions as societal transformation. The definition of disposition is mainly related to teachers’ characteristics. The definition provided by the National Council for Accreditation of Teacher Education (NCATE) in 2008 emphasizes the importance of dispositions as professional attitudes, values, and beliefs that teachers express through both verbal and nonverbal behaviors [
38]. These dispositions are important as they are related to the ability to relate positively and professionally to students, families, colleagues, and the community. A teacher’s personality is directly related to student academic success, particularly the teacher’s communication skills, honesty, and motivation [
42,
43,
44]. West et al. [
45] stated that motivation to teach, teacher efficacy, willingness to learn, conscientiousness, and interpersonal communication skills are the main characteristics of the teacher’s profession.
A teacher’s motivational personality affects working enthusiastically, increasing professional involvement, leading, developing, and creating value [
46,
47]. Rubdy et al. [
48] and Dörnyei Ushioda’s [
49] research is helpful for understanding how motivation is not a linear and static process but a complex dynamic involving multiple factors: the initial reasons for undertaking an activity (initiating and sustaining motivation) and the internal and external resources needed to maintain it over time. In addition, the motivational character of the teacher makes the student actively motivated to learn [
50]. It is observed that the characteristics of modern student’s behavior are that they are reprimanded and pushed with too many tasks, which is likely to hurt the learning outcomes. Rather, it is more necessary to encourage and motivate them to learn effectively by treating them kindly, listening carefully to their intentions and supporting them. Therefore, we believe this is one of the important leadership qualities that a teacher should have.
Teacher self-efficacy is one of the most important factors in teacher leadership. Bandura [
51] first wrote about this personality within the socio-cognitive theory developed by social scientists. This character is the quality of a person’s actions to achieve desired goals confidently. Teacher self-efficacy increases their ability to lead in any activity. A self-confident person can lead others and help them achieve their goals.
On the contrary, a person lacking self-confidence is less likely to be listened to and followed by others. Especially in schools, teacher self-efficacy may be conceptualized as individual teachers’ beliefs in their abilities to plan, organize, and carry out activities required to attain given educational goals [
52]. Therefore, this quality is one of the most important qualities that a teacher should have because a teacher can be confident in front of their colleagues and students and lead them to work and learn successfully.
Willingness to learn is an important aspect of teacher leadership. A willingness to learn is an impulse, desire, or readiness to acquire new and developing knowledge [
53]. In other words, people willing to learn constantly seek new things, do not stagnate in development, and follow modern trends. Factors that influence employees’ willingness to learn and share knowledge are the perception of organizational culture, trust, infrastructure, and leadership [
54].
Conscientiousness is one of the professional characteristics that influence effective teacher leadership. It is defined as an individual’s ability to show self-discipline and strive for competence and achievement [
55]. Conscientiousness is an important quality of an individual to perform their duties well and be disciplined. According to the Five-Factor personality theory, conscientiousness is a quality that is more suitable for people with leadership skills, long-term planning, communication support, and technical skills [
56]. Conscientiousness is the most reliable measure of leadership effectiveness. Singh [
57] also argues that extraversion and conscientiousness are important personality attributes for leadership effectiveness. According to the above researchers, conscientiousness is one of the important qualities that everyone should have. In our research, this personal quality is one of the most important professional dispositions for a teacher because the teacher is the most important person who influences their students to learn in a disciplined, responsible and conscientious manner. From this teacher characteristic, students are more likely to learn again and become good leaders in the future.
Interpersonal communication skills are the most important qualities that teachers should have in educational institutions. The main focus of today’s educational organization is interpersonal relationships. University is a learning environment, and sharing knowledge and experience, teamwork, intellectual modeling, and systematic thinking are most important in daily school life because they manifest in interpersonal relationships [
58]. Therefore, communication competence is one of the key factors for effective work and well-being of employees. Hence, modern researchers [
59,
60,
61,
62,
63] underline the importance of human interpersonal communication competence.
Therefore, a form of teacher leadership in the university environment is manifested in their interpersonal relationships. Wood [
59] and Purhonen [
60] argue that interpersonal communication depends on the context or a particular situation, people’s ability to communicate and their motivation, listening skills, cultural literacy, language, as well as skills marked by Wood [
59], namely “developing a range of communication skills; adapting communication appropriately; engaging in dual perspective; monitoring communication; and committing to effective and ethical interpersonal communication”. From the above research, we have seen that the main characteristics of the teacher’s professional personality influence the teacher’s enthusiasm for leadership.
According to the literature review, the teacher’s disposition and leadership positively affect student learning satisfaction. In our study, we examined a theoretical model proposing that teacher leadership mediates the relationship between student learning satisfaction and teachers’ professional dispositions in the context of higher education.
Our research is proposed following the research model (
Figure 1).
Considering the literature review, we hypothesize that teachers’ positive leadership will affect students’ learning.
H1. Teacher leadership positively influences student learning satisfaction.
H2. Teacher communication positively affects teacher leadership.
H3. Teacher conscientiousness positively affects teacher leadership.
H4. Teacher motivation to learn positively affects teacher leadership.
H5. Teacher efficacy positively affects teacher leadership.
H6. Teacher willingness to learn positively affects teacher leadership.
