In general, the motivation theories can be classified into either the content theories or in the process theories. The first deals with the motivation and concerns for identifying the needs of people and their related forces, as well as the goals they seek to meet those needs. The basic content theories include the hierarchy needs of Maslow [
1], Herzberg’s Two Factors theory [
3] as well as McClelland’s theory of motivation [
4,
5]. On the other hand, process theories give emphasis on the real process of motivation. These theories deal with the relationship between the dynamic variables which constitute motivation and on how behavior starts and is directed and maintained. Some good examples are models based on expectation, the theory of goals of the equality theory as well as the distribution theory [
6]. Self-Determination Theory, which is a general paradigm for studying human motivation and personality, lays out a meta-theory for framing motivational research, a systematic theory that distinguishes intrinsic and extrinsic origins of motivation, and a definition of the functions of intrinsic and extrinsic motivation in cognitive and social progress, as well as in individual differences [
7].
The concept of internal motivation is directly linked to the one of performance. The term “performance” is a synonym of behavior. It is something that people do for real, and it can be observed. Specific incentives are designs to have predetermined criteria and standards, as well as understandable policies for the determination and distribution of rewards. Although money is possibly the most used incentive, incentives include anything provided by an external factor, dependent on the fulfillment of specific behavior standards. Thus, promotions, grades, awards, health benefits, praise and recognition are all incentives.
Literature Review
Several studies have been designed in order to examine the concepts of teachers’ motivation and incentives. The study of [
12,
13] was designed to examine the factors affecting the teacher’s level of motivation at secondary education. The conclusion that emerged was that teachers were not satisfied with the socioeconomic situation, the choice of their job, the behavior of students and the stress of the exams, whereas many of them considered that their wage is not satisfactory for the level of their abilities. Thus, it was proposed that teachers should educate, receive the proper respect and get paid according to their qualifications and abilities.
The study of Hildebrandt and Eom [
14] examined the motivational factors of teachers who have achieved a national level of vocational training. Using bilateral, online research, multiple incentives concerning the professionalism of teachers were revealed, with teachers of different ages who are motivated by different incentives. The objectives were developed based on previous researches and separated in different categories: the economic profit, recognition and affirmation, personal satisfaction, career development, career promotion, enhanced leadership role and the opportunity to cooperate with other teachers as they become better.
The improved teaching incentives represented teachers’ desires for career and educational development. The previous studies indicate that teaching usually urges teachers to engage in career training activities. For example, Peker underlined that the improvement of practice and the enhancement teacher’s job are usually referred as incentives [
15]. “The Center for the Future of Teaching and Learning” found that strengthening the teaching of everyone is directly related to obtaining a certification and, therefore, to the concept of professionalism [
16]. Given that professionals constantly develop skills and knowledge [
17], the ability as a psychological need [
18] and the motivational factor are crucial. Financial incentives were used as an independent variable in this study, which enhances the popularity of the subject in current educational policy cycles. This research underlines the sustainability of economic profit as incentive for teachers.
In this context, Kelley and Kimball [
19] found that money was initially a strong attraction tool in the process of professionalization, but later, this attraction declined as other incentives were strengthened. Certain countries and regions provide some teachers who get certified and specialize more and more with economic incentives, although this kind of practice changes in today’s economic environment [
15]. Given the relatively low wages of teachers compared with other sectors, motivation is an interesting and crucial factor for this study.
The synergistic opportunities appeared as other motivational factors. Peker (2004) mentioned that it was the most commonly mentioned incentive for certification from their participants, and Park et al. found that the teachers’ interactions, as they work towards professionalization, made cooperation easier [
15,
20]. Past research on teaching environments and collaborative opportunities has shown that teachers often work individually [
21], while more recent research has shown that teachers responded more positively when given the opportunity to work with others [
19]. The independence of this factor indicates that cooperation is incentive for the certification and the professionalism that accompanies it. This factor is further supported by [
22], who emphasized that teachers’ cooperation was an integral part of their career development. Finally, the incentive of cooperation strengthens the psychological need for kinship among teachers.
Teachers’ relationships are an important factor in their development. In many cases, these are directly related to the relationship between teachers and parents. Teachers appeared to see their relationships with parents favorably when they indicated high levels of psychological empowerment or were more likely to see their organizational culture as a group, developmental and hierarchical culture [
23]. Finally, after adjusting for the ethnic profiles of teachers, psychological empowerment and organizational culture uniquely predicted teacher-parent relationships.
Affirmation is an interesting source of incentives for teachers in this research, although it did not constitute a single factor. Internal and external affirmation, as independent factors, came up from the data content of this research. Supporting this difference, Fernet differentiates these control positions, explaining that the particular adjustment is the behavior that people choose to execute because it is in accordance to their own values and goals, whereas the external adjustment occurs when behaviors adjust in order to obtain a reward or to avoid a restriction [
24]. Internal affirmation is a basic incentive, because teachers do not necessarily receive external affirmation. In this context, teachers of California found “personal challenge” as one of the most important incentives for the certifications to occur, and Ozcan used “honorary rewards” in his model regarding teachers’ motivation as he described the “social honor, status and recognition” [
4,
25].
This multifaceted concept of incentive for professionalism strengthens the previous research, whereas it decomposes specific major categories of incentives for teachers. This multidimensional structure of incentives seeks to encourage further discussions between teachers, researchers and others with regards to why teachers choose to pursue professionalization, especially if it is not mandatory [
26]. Professionalization and growth are especially necessary when hiring, training and retaining teachers who are dedicated to equitable education in both developed and developing countries, which are historically, and currently, underserved and underserved much too often [
27].
During the last two decades, many studies have tried to locate sources of both satisfaction and dissatisfaction for teachers of all educational levels [
12]. According to the majority of these studies, the satisfaction of teachers relates to the levels of introspection i.e., with the incentives. The main factor that contributes to the teachers’ work satisfaction is the interaction with children. Additional factors were the development of warm, personal relationships with the students, the spiritual challenge of thinking, autonomy and independence. On the contrary, many teachers faced job dissatisfaction, focusing mainly on work overload, poor pay and perceptions of how teachers are treated by society. In general, however, studies have found differences in teacher satisfaction with work, depending on certain individual and school characteristics [
28]. Job dissatisfaction can lead to exhaustion, the increase in job stress, and, in this case, the burnout of a teacher may appear [
29]. Four key categories have been categorized into factors influencing or affecting job satisfaction/dissatisfaction and motivation: human factors, actual work factors, organizational factors and social context factors. These factors were investigated and it came out that teachers can be satisfied when specific activities, regarding their daily activities, can be completed on time [
30].
According to Zembylas and Papanastasiou, the satisfaction of teachers refers to the emotional relationship of teachers with their teaching role, and it is a function of the perceived relationship between what one wants from teaching and what he actually realizes is offered to a teacher [
31,
32]. Those who have the biggest desires or the highest ambitions are less pleased with their job if the environment does not satisfy their needs. In this context, Maeroff characterized teachers’ “feeling of empowerment” as an important way “to make teachers more professional and improve their performance”. The power that Maeroff mentioned, is “the power of someone to practice art with confidence and to contribute to the formation of the method with which the work should be done” [
33].
The results of the above research indicated that the teachers in Cyprus chose the job of teaching staff for inherent reasons, as the majority of them stated that they always wanted to become teachers. Nevertheless, a more careful look at these data revealed that it was the level of wage, the working hours and the duration of vacation period which made teachers choose this career. The preliminary investigation of the results of this research confirms what it has been found in other studies in developed countries, that the motivation of teachers (native or exogenous) relates to the work satisfaction. The interpretation we can give from the Cypriot example is that the higher the teachers’ exogenous motivation (wage, work conditions), the more satisfied they are with their job.
The total results of these two analyses show that it is more possible for teachers who had a more realistic opinion for their job, before they start their training, to be satisfied with their career. Moreover, people who always wanted to become teachers and never experienced any pressure from their family to follow this career, it is more possible to be satisfied with the role of the teacher.
The consensus among researchers is that extrinsic factors, such as remuneration, working conditions, teaching equipment and resources and job security, or intrinsic factors, such as self-growth, self-efficacy, motivation and autonomy, to name a few, may influence job satisfaction. Past research results provide insights into the effect of both intrinsic and extrinsic factors influencing the satisfaction of teachers [
34,
35]. Iwu supports that interpersonal relationships is the key factor that affects the commitment of teachers to work [
36].
