Perceived Satisfaction of Teachers about the Practices of Leaders of Religious Institutions to Promote Peace Education

Practices of the leaders of religious institutes are fundamental in promoting peace education as their practices leave an immense impact not only on the perceptions and practices of teachers but also of the students regarding peace education. The beliefs, interests, inclinations, moral values, and competency of institutional leaders are reflected in policies they make and are presented in the practices of teachers. Owing to the importance of their practices aimed to promote peace education, there is a need to identify the extent of these practices as they are perceived by direct stakeholders, that is, teachers, which makes the aim of the current study. This research is a quantitative survey-based research. The population of this research includes the teachers of religious education institutes of Lahore. Cluster sampling method was used for the selection of sample. Data was collected from the teachers teaching to final year students and a total of 292 teachers participated in the study. A self-developed instrument was used to collect data. The instrument was based on the factors of peace education and practices used to promote them from the literature. The instrument was pilot tested and the validity and reliability of the instrument was established that was 0.87. The data was analyzed using descriptive and inferential statistics. The results indicated that teachers were satisfied with the practices of the leaders of religious institutes aimed to promote peace education. This study may help the academicians, practitioners, and policymakers to promote peace education in all schools of Pakistan.


Introduction
Peace is not an alien word in all religions and cultures. If we search for the word "peace" in the Qur'ān, it appears more than 57 times. Thus peace has prime importance in the society. It is stated in Qur'ān "Peace!"a word of salutation from a Lord Most Merciful." 1 Peacemaking is a hall mark of an Islamic society as it is asked in Qur'ān as "It One can visualize the world if the peace is established as the description given in the Qur'ān "If two parties among the Believers fall into a quarrel, make ye peace between them: but if one of them transgresses beyond bounds against the other, then fight ye [all] against the one that transgresses until it complies with the command of Allah; but if it complies, then make peace between them with justice, and be fair: for Allah loves those who are fair [and just]." 9 There is a growing consciousness in Pakistan that children should be educated in the art of peaceful living. Pakistan is presently a great representation of a nation that needs harmony; its way of life is divided by class, financial matters, legislative issues, philosophies, religion, language, territory, color, and caste. The young generation, especially the school-going youngsters, are affected by this sort of turbulence. They experience this culture through their families, schools, and the cultural channels of communications, for example, the media, and other social organizations and products. 10 DEPARTMENT OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020 Williams (2004) states that violence influences schools at different levels by attacking people, networks, and systems, and "weakening their sense of agency." Murithi (2009) states that: The type of world that we as human beings create in the future will depend on our ability to reject violent and militaristic approaches to solving problems. Peace education should therefore be a central pillar to improving human relations in the family, in schools, at the workplace, within countries and across borders. 11 Begum, A. (2012) in her study that investigated the perceptions of teachers about peace education, shared thoughts by teacher A in the following lines, Our societal culture is full of turbulences based on economic, socio cultural, political and religious grounds. This culture definitely exerts a huge influence in the school through teachers and students. This also creates a problem for peace education and cultivation of a peaceful and friendly environment in the school.
She further states that, the educators seem to comprehend the possibility of peace education and have clarified it in a few different ways that you are practicing in the educational institutions, yet they couldn't give any proof of their useful work in an arranged and composed way. Thus, such association may be considered it as a chance requiring for a harmony in instruction mediation. The teachers seem to understand the idea of peace education and they describe multiple ways that are carried out in the school yet they were incapable to exhibit practical work/activities in a planned and organized manner. Therefore, such organization may be considered as an opportunity and need for a peace education intervention.
Keeping in view the above notions, practices of leaders of religious institutions are fundamental to the promotion of peace education as their practices leave an impact on the perception and practices of teachers regarding peace education. Besides, the personal religious beliefs, interests, inclinations, moral values, and competencies of school leaders play an important role in this context as these elements are reflected in the practices employed by them. Therefore, the practices of school leaders affect the perception of teachers and they work accordingly and it can be assumed that practices of school leaders are reflected in the work of teachers. Thus, school leaders as head of the institutions can influence teachers and students to promote peace education through their practices, and by doing so peace-loving citizens can be produced.
The leaders of religious institutions are key agents/actors in promoting peace practices in their schools. Being the leaders of their schools, they have a vital role and have influence on teachers and students in connection with achieving institutional and desirous goals. There are researchers, like Harris and Synott and Baxter and Ikobwa, who have emphasized the important role of (peace) educators in influencing the success of peace JOURNAL OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020 education initiatives. The practices of the leaders of educational institutions to promote peace education play a vital role in this regard as the effects of their practices are the perceived satisfaction of teachers. 12 The focus of peace education is to develop an appreciation for the global connection of all humanity and our interdependence on the finite natural resources of the earth. Peace education is defined as a process of "moral inclusion". Moral inclusion is an essential and strategic principle of peace education 13 and because it stands for the willingness to extend fairness to others, allocate resources to them, and make sacrifices for the well-being of others. 14 The prime concern of peace education is the reconciliation of society, the protection of human rights, and the development of peace skills. 15 The protection of human dignity, the transformation of a society into a peaceful and harmonious society is possible through the peaceful practices of educational institution's leaders as they have a greater influence on the perception of teachers as leaders. Hence, the practices of leaders to promote peace education influence the teachers to become an instrument of peace for the common good of society.
In the education system of Pakistan, peace education has been merged with religious education which is considered to provide grounds for social co-existence, peace, and harmony for a prosperous society and the unity of the country. The practices of institutional leaders to promote peace education is to know skills, values, attitudes, and information to achieve peace which will enable learners and young generation to live in peace and harmony but there are examples of learners in the religious schools where due to individual differences learners differ with one another and it is also reflected in the society at large. Also, the political, social, religious, and economic situation of the country shows the need of peace education in the schools in order to have prosperous society.

Promoting Peace through Education
Peace education has gained the reputation as a field of education, but it is still very complex and needs clarity. 16  operationalization of the construct calls for the researchers to explore the field further. 17 A broad definition of peace education suggests that it is a philosophy, pedagogy and a process. A philosophy that promotes peace, emphasizes on love, creates harmony, passion, empathy and thus removes violence from the society. The pedagogy is that focuses on developing skills and attitudes to transform societies for promoting nonviolence actions and the process that brings peace into the culture. 18

Role and Practices of Institutional Leaders
In the daily course of life, a school principal encounters a multitude of responsibilities and complex professional tasks. Institutional leaders has to perform various duties such as they are to act as change agents, economic analysts, education leaders, managers for efficiency, mentors to develop values, and guides for morality. 19 Moreover, the leaders of the religious institutions of the contemporary era are facing heavy administrative roles, in order to meet various expectations from certain stakeholders such as parents, teaching staff and the community concerned. 20 Some of the seminal studies showed that culture enhancing students' learning was characterized for the effective schools. 21 In this connection the role of leaders of religious institutions along with teachers was identified as a main and crucial factor. 22 Therefore, the role of school head has been evolving and ever changing besides the role of being a leader. The role of institutional leaders can be categorized into rules developer, capacity builder and administrator in order to develop effective organizational culture. As an institutional head, he/she is sole responsible agent 17 Daniel Bar-Tal, "The Concept, Principles, and Practices around the World," in The Elusive Nature of Peace Education, Peace Education (2002) for building an effective culture. 23 An institutional head must act as a manager, an administrator, and a mentor facilitator in order to make improvement in the culture. 24 Roles and practices of school principal demand from them to create a viable culture suitable for education. 25 However, school level variables are considered to have lower degree of impact on school culture. 26 Therefore, effective practices by leaders of religious institutions may synergize with school level variables to show a higher effect. Effective practices by institutional leaders harmonize well with contextual factors to create a viable culture for both teachers and students. 27 Effective practices showed influential effect on overall school performance, climate and teachers' performance. 28 The institutional leaders set certain rules, performance expectations and administrative measures to induce a positive educational culture, hence, they are able to produce professional quality from teachers and students. 29 Effective practices foster better communication, coordination and create an effective school climate.

Evolvement of Institutional Leaders' Practices
Historically, the institutional leaders were not considered responsible solely for creating educational culture and improving students' achievements. The role and practices of institutional leaders have evolved with the passage of time with the changed expectations of the society 30 . With the emergence of leadership's administrative roles, the heads of educational institutions have managed the extra roles such as building effective educational culture. Moreover, the school reforms have also shaped the roles and practices of institutional leaders to meet the contemporary demands in education. Therefore, today, DEPARTMENT OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020 leaders of religious institutions are expected to act as rule setter, capacity builders and administrative reformers.
During early years of nineteenth century the concept of principal teachers emerged. During that era teachers were assigned an additional role of institutional leadership and they had not specific instructional responsibilities. 31 At that particular time the role of the head of the institution was just to meet the clerical requirements. Even the institutional leaders were not assigned the duty to hire the teachers, for that purpose town meeting were held and teachers' recruitment process took place. 32 With the passage of time the schools grew in size and communities emerged so some teachers were assigned organizational duties such as, cleanliness, maintenance of equipment and maintaining attendance. 33 Along with the mentioned roles and duties, the role of administrative roles of institutional leaders during that era was also to maintain the facilities in the classrooms. After some time, the role of institutional leaders emerged as liaison as they worked as a link between school and school district. 34 District office at that time was not concerned with instructional role of principal teachers, rather their mere concern was the improved day to day operation of schools. 35 By the end of the nineteenth century almost all the schools had a principal teacher to ensure the completion of all the daily occurring tasks.
Gradually, the teachers were given additional tasks such as discipline maintenance and requisitioning of supplies. 36 Ultimately, larger schools met the designation of institutional head or the school principal. 37 At the start of twentieth century, the change in educational institutions was realized and the role of institutional leaders emerged as professional leaders. The leaders of the educational institutions were assigned all the important role of administration. For example, the school leaders were given bureaucratic roles and they were now working as professional school leaders rather than principal teacher. However, worth to mention here that rural areas were still neglected to have a professional principal. The professional institutional leaders in urban area had a role of administrators. The duties of professional institutional leaders included hiring the teachers, terminating them and also 31 Linda J. Gill assigning the teachers with duties. 38 Moreover, institutional leaders were expected to act like supervisors to the teachers to ensure the quality of teaching. 39 With the passage of time and growing size of schools, the need of additional staff was also felt. So, the additional staff such as clerks, admission officers, attendance keepers and maintenance workers were also given the supervision of the institutional leaders. 40 The repair and maintenance duties were also assigned to the institutional leaders. 41 The leaders of institutions at that era were mainly concerned with typical administrative duties such as attendance, communication, class assignment, and provision of supplies and personnel management rather than the instructional practices.

Teachers' Perception of the Institutional Leaders
Teachers perceive the institutional leaders as the system designer and organizer, as an influencer, a creator of harmonious working environment, a stimulator for teachers' job satisfaction, as a head of the entire structure, a peace mobilizer and mediator, and a caretaker of the teachers' rights. In a nutshell, the leaders of educational institution are the persons who lead the schools' entire organizational structure with his/her in-depth foresight and with most effective and efficient decisions.

Conceptual Framework
The current study aimed at identification of the perceived satisfaction of teachers about the practices of institutional leaders to promote teacher education. The underlying assumption is that the practices of institutional leaders play an importance role in, developing perceived sense of satisfaction of teachers about the promotion of any phenomenon, so in current study it will be investigate how the practices influence the perceived satisfaction towards promotion of peace education. The practices of institutional leaders can be divided into three main categories of i. rule developer, ii. Capacity builder and iii. Administrator. These three categories were further sub-divided into twelve categories including; (i) developing codes of conduct for classes, (ii) developing a school discipline guide, (iii) practices for developing self-esteem, (iv) using special activities and exercises for developing peaceful competencies, (v) moral instruction for the day, (vi) school/classroom wallpaper, (vii) displaying peace mottos (viii) peace day/week, (ix) appointing class mediators, (x) appointing a peace committee, (xi) conducting morning assembly and (xii)  These practices are important in determining the peace education promotion in educational institutions among the institutional leaders. Therefore, the current study focuses on the relationship institutional leaders' peace education practices and its perception by teacher in private schools. The following figure 1 presents the conceptual framework of the study.

Methodology
This research study is quantitative in nature using survey research design and aiming to collect data from large number of population. The study was limited to religious education institutions owing to the permission by the institutional leaders to collect data from teachers.

Objectives of Study
Following are the objectives of study: 1. To identify the perceived satisfaction of teachers about practices of institutional leaders to promote peace education 2. To identify role of demographic variables on perceived satisfaction of teachers about role of institutional leaders in promoting peace education

Research Question
The research questions based on each objective of the study are as follows: The targeted population of the study was 1219 religious educational institutions in a metropolitan city. Though the unit of analysis was all the teachers working in these schools but the population of teachers working in these institutions remained unknown due to unavailability of actual data.
The convenient sampling technique was used to collect data from the teachers. About 450 questionnaires were distributed from which 327 were returned with the response rate of 72.66 %. Out of 327 respondents, 35 were not included in this study on the basis of missing data. Remaining 292 responses were used for the analysis of the data.

Instrument of the Study
In order to collect data a survey instrument entitled "perceived satisfaction of teachers with the institutional practices for promoting peace education". It was a self-developed instrument with two main parts: first part was intended to collect biographic data while the second part was focused to perceived satisfaction of teachers about role of institutional leaders' practices to promote peace education. The information inquired in the first part of the instrument was about age, gender, prior training, experience and qualification. While second part was composed of three factors that were subdivided into twelve sub-factors focusing on perceived practices of institutional leaders. Following table presents, subfactors and their subsequent number of items. Appointing a peace committee The morning assembly School link programs 2.3.1.1. Pilot Validity and reliability of the instrument were established before administration to sample. The validity was ensured by using Lawshe's model of content validity ratio by taking expert opinion from seven experts from the field of education and political sciences. After responses were collected the content validity index (CVI) was DEPARTMENT OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020 calculated manually by applying standard formula for each sub-factor and as a whole for instrument 43 .The overall value of CVI for the instrument was .87.
The instrument was pilot tested on sample of one hundred teachers (other than sample) in order to establish reliability of the instrument, later the Cronbach alpha values was calculated for sub-factors and factors, following table presents both values. The frequency scale was used for the instrument ranging from 1 (never) to 5 (always). Total number of items before validity were 87 which were reduced to 39 after validity and reliability tests. Ethical considerations were kept in view before data collection and respondents were given a brief on purpose of study, data collection process and confidentially of the data. Only the participants who volunteered after briefing took part into the study without any incentive or pressure.

Results
In the following section, the results will be discussed according to the objectives and research questions of the study. The collected data were entered and cleaned using SPSS software. The following table presents the percentage of respondents. In order to achieve the aim of the study data from 292 teachers was collected from the various schools of a Metropolitan city of the country. Table 2 states that, the majority of the teachers fell into the age group of 20-25 years catering 34.2% of the total sample, whereas, other major age categories are as follows: 26-30-year age group (24.3%), 31-35 years age group (15%). However, the lowest age group was found above 50 years only (1.4%) of the whole sample. There were more female teachers in the sample data (82.5%) than male teachers (17.5%). Regarding the school type, two types of schools were catered for the study higher socio-economic schools (52.4%) and lower socio-economic schools (47.6%). As far as the training acquired is concerned, the data revealed teachers who acquired training (49.3%) and who did not acquire the training (50.7%) are almost the same. The job experience was also the part of this study and data revealed that most of the teachers were having an experience of 1-5 years (47.7%) after that 6-10 years of experience and 16-20 years of experienced teachers (5.5%) were the lowest in the data. Most of the teachers' qualification was Graduation. (53.4%), whereas, respondents with a master's degree were 38.7%, and very few of the teachers were having M.Phil. degree 7.9%.

Objective one: Up to what extent teachers perceive their institutional leaders' peace education practices are satisfactory?
The first objective and its respective research question of the study was to determine the perception of the teachers about principal's practices in connection with the promotion of peace education. The section of the questionnaire, regarding principal's practices about peace education was based on three main factors, which had further twelve factors, in the reflection of peace education practices, i.e.; rule developer, capacity builder and administrator. Descriptive statistics on scores of teachers' perception for peace education is given in following table  The table 3 shows the descriptive analysis of teachers' perception in terms of mean, mean per item (MPI), and standard deviation of the factors, constituting questionnaire, regarding institutional leaders ' practices to promote peace education. According to the table, the teachers responded to be inclined towards the presence of practices in institutional leaders to promote peace education in the schools of Lahore (MPI = 3.70, SD = 30.25). It shows that the teachers of schools in Lahore, perceive their institutional leaders are following practices to promote peace education.
As identified in the theoretical framework of the study, three factors of peace education practices were identified, i.e. rules developer, capacity builder and administrator. Analysis report indicates the perception about rules developer practice was the strongest perception in the teachers (MPI = 4.23, SD = 4.23). After that administrator role of institutional leader was perceived in an attempt to promote peace education (MPI = 3.60, SD = 11.84), whereas, the lowest perceived practice was capacity builder (MPI = 3.33, SD = 14.18).

Objective two: How demographic factors influence the perceived satisfaction of teachers about the practices of institutional leaders in promoting peace education
Multiple demographics including bio-graphics (age, gender) and professional factors (including experience, qualification and training) were included for the identification of effect on perceptions. Each of them is separately tested with total score of the instrument. Following tables shows the tests and consequent results.
In order to explore the gender difference between male and female teacher that how they develop a perception about their leader's practices in promoting peace education, an JOURNAL OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020 independent-samples t-test was conducted to compare the difference in perceived satisfaction among males and females. According to the table 4.3, there was not a significant difference in the scores for male teachers (M = 150.78, SD = 28.82) and female teachers (M = 144.33, SD = 26.22); t (292) = 1.26, p = .126, in perception about institutional leaders' practices to promote peace education. These results suggest that the gender has no difference in perception about institutional leaders' peace education promotion in teachers of educational institutions.
In order to explore the institutional difference in high socio-economic and low socioeconomic schoolteacher that how they develop a perception about their leader's practices in promoting peace education, an independent-samples t-test was conducted to compare the difference perceived satisfaction in high socio-economic and low socio-economic educational institutions.
According to table 4, there was not a significant difference in the scores for the teachers working in high socio-economic schools (M = 144.18, SD = 25.48) and teachers working in high socio-economic educational institutions (M = 146.87, SD = 29.29); t (292) = -.838, p = .403, in perception about school leaders' practices to promote peace education. These results suggested that teachers working in high and low socio-economic school types have no difference in perception about institutional leaders ' peace education promotional practices in educational institutions.
In order to explore the teachers' training difference that how they develop a perception about their head's practices in promoting peace education, an independent-samples t-test was conducted to compare the difference perceived satisfaction in teachers with training acquired and teachers with no training acquired.  One-way ANOVA test was conducted to compare the effect of teachers' age on their perception of institutional leaders' practice of peace education in age bracket of group 1 (21-25 years), group 2 (26-30 years), group 3 (31-35 years), group 4 (36-40), group 5 (41-45), group 6 (46-50) and group 7 (above 50). Table 4.6 shows the results of one-way ANOVA test between different age groups of teachers to compare their perception institutional leaders' practices for peace education.
According to table 4.6, there was a significant effect of age of the teachers on their perceived satisfaction at the p < .05 level for the seven groups of age [F (6, 285) = 2.41, p = 0.027]. It shows that the teachers with different age groups have different levels of perception about institutional leaders' peace education practices.
Tukey post hoc test indicated that there is significant relationship between the age group 41-45 years and 46-50 years of teachers and their perception about institutional leaders ' peace education practices (p < .05). It means that the teachers of age group 41-45 years and 46-50 years have stronger perception about their institutional leaders' peace education practices. On the other hand, there was found no significant difference between all the age groups (p > .05). (Table in Appendix)

Experience influence the teachers' perception about school leaders' practices for peace education
One-way ANOVA test was conducted to compare the effect of teachers' experience on their perception of institutional leaders' practice of peace education in experience bracket of group 1 (1-5 years), group 2 (6-10 years), group 3 (11-15 years), group 4 (16-20), and group 5 (Above 20 years). The table 4 shows the results of one-way ANOVA test between different age groups of teachers to compare their perception institutional leaders' practices for peace education.

Does qualification influence the teachers' perception about institutional leaders' practices for peace education?
One-way ANOVA test was conducted to compare the effect of teachers' qualification on their perception of institutional leaders' practice of peace education in experience bracket of group 1 (Graduation), group 2 (Masters), group 3 (M.Phil.). Table 4 shows the results of one-way ANOVA test between different qualification groups of teachers to compare their perception intuitional leaders ' practices for peace education.
According to table 4, there was a significant effect of qualification of teachers on their perceived satisfaction at the p < .05 level for the seven groups of age [F (2, 289) = 11.11, p = 0.000]. It shows that the teachers with different qualifications have different levels of perception about institutional leaders' peace education practices.
In order to explore the effect of qualification-related effect of teachers' perception, post hoc test was conducted. Table 4 illustrates multiple comparisons among qualification groups and teachers' perception about intuitional leaders' peace education practices. The Tukey post hoc test indicated that there is significant relationship between all the qualification groups and their perception about institutional leaders' peace education practices (p < .05). It means that the teachers of all qualification groups have stronger perception about their institutional leaders' peace education practices.

Discussion
It is the need of time to consider the importance of peace education in the countries that have been in the condition of unrest. It was unique area of inquiry to explore the practices of a school principal as perceived by teachers which can ensure peace education. Only few empirical researches were found in the literature based on peace education practices by an educational institution 44 ; 45 ; 46 . In view of this gap in knowledge with regards to the prerequisite skills to perform tasks to promote peace educational practices in schools, this study finds important practices which are necessary for institutional leaders to promote peace education. Moreover, this study also finds an important area that what the expectations of teachers from their institutional leaders are. This gap in literature may also hurdle the process of institutional leaders' training programs to enable them to prepare with needed skills of the 21 st century in order to promote peace education. It is important to measure peace education practices in fragile and conflict affected countries. 47  literature indicated the importance of peace education that can transform teachers of an institutions. 48 Therefore, the need to investigate the role of institutional head, such as principal, in promoting peace education is very important.
The findings of the current research indicated that practices in promoting peace education by a institutional leaders in Pakistan are consistent with that of the framework identified by the literature. Moreover, the perceived satisfaction of teachers from institutional leaders were also identified. There was found not any significant difference between teachers' perception about institutional leaders on the basis of gender, school type, experience and training acquired. According to the perceived satisfaction of teachers, with regards to the age and qualification was identified. Owing to the presence of peace education practices in institutional leaders, the teachers identified these practices in their leaders.
Moreover, the institutional leaders found to be more likely to instill a positive change in the teachers with respect to the practices for peace education. As far as bringing about the change through peace education in schools is concerned, there is contradiction between different authors. For example, schools are not the proper sites to bring about change as schools promote status quo 49 . While Christopher and Taylor argued that classrooms at school are an important place where the change occurs and peace education at the same place can transform teachers and students at the same time 50 . Moreover, Brantmeier also argued that peace education in schools transforms teachers at the first place and these teachers then become the important source of change process. 51 This research also proposes that school leaders are the nucleus of peace education and through them the radical change is observed in teachers. Institutional leaders play an important role in shaping a positive perception in teachers and students about peace education, who in return become an important element for the society. 52 JOURNAL OF ISLAMIC THOUGHT AND CIVILIZATION Volume 10 Issue 2, Fall 2020

Conclusion
This study explores the peace education practices of an institutional leaders and perception of these practices in teachers. This area of inquiry was neglected in the existing literature. However, this study starts with the importance of education in conflict affected and fragile states. Literature reveals that literacy rate is quite horrible in fragile states due to the less spending on education. Moreover, international authorities are also unable to address this issue. In fragile states, like Pakistan, where there is a situation of internal war and educational sector has not taken the attention of governmental spending. Owing to this important reason, the behavior of such fragile states has changed very rapidly. As internal war has affected the individuals in shaping their attitude and behavior, so a severity has been observed in the people of such countries. Education is the only weapon which can take care of the behaviors of the people in countries like Pakistan. In this connection peace education is an important tool to eradicate severity in the behaviors of the people. In this connection, schools are found to be an important place from where the peace education can be initiated. Literature on peace education is lacking on the practices of a school principal to promote peace education, so this study has explored some important practices to promote peace education in schools. Moreover, how these practices are perceived by schoolteachers and students. This research found that peace education practices are positively perceived by the schoolteachers.
