The purpose of this study is to reveal the extent to which different leadership models in education are studied, including the change in the trends of research on each model over time, the most prominent scholars working on each model, and the countries in which the articles are based. The analysis of the related literature was conducted by first employing a bibliometric analysis of the research and review papers indexed in the Web of Science database between 1980 and 2014. Then, a more in-depth analysis of selected papers was done using the content analysis method. The results showed that there has been increasing interest in leadership models in educational research over time. Distributed leadership, instructional leadership, teacher leadership, and transformational leadership are the most studied leadership models in educational research. It was also found that related research increasingly focuses on the effects of leaders on organizational behaviors/conditions and on student achievement. Accordingly, usage of quantitative methodology has significantly increased during the last decade. Possible reasons for these changes, implications, and recommendations for future research are also discussed.

Policy, practice, and reality: exploring a nation-wide technology implementation in Turkish schools

Mete Akcaoglu; Sedat Gumus; Mehmet Sukru Bellibas; D. Matthew Boyer

Technology has already become an indispensable part of our lives, and nations around the world see schools as the main agents to prepare their youth for a technology-filled future, and invest important amounts of funding to provide hardware to schools, students and teachers. The Turkish Ministry of National Education is in the midst of the FATİH project, a nation-wide attempt to provide each classroom with an interactive whiteboard and each student with a tablet computer. In this paper, the authors present interview data from teachers at first-year FATİH pilot schools who are using these technologies to understand how this national attempt is being translated into practice, and identify what is working and what areas need further attunement. Results show that teachers were especially content with being able to make their lessons visually more appealing for their students. They were, however, not satisfied with the in-service training provided, especially in understanding ways to effectively integrate the technologies into their teaching, and the limitations put upon Internet access from the tablets. The impacts of these tools on their teaching practices were very minimal.

The effects of principals’ perceived instructional and distributed leadership practices on their perceptions of school climate

Mehmet Sukru Bellibas; Yan Liu

Abstract The purpose of this study was to investigate the extent to which leadership styles predict school climate, in order to identify whether a relationship exists between principals’ perceived practices of instructional and distributed leadership and their perceptions of school climate (mutual respect and school delinquency), controlling for a net of principal and school characteristics. This research was conducted on a principal data-set from the 2013 Teaching and Learning International Survey (TALIS), which was administered by the Organization for Economic Co-operation and Development (OECD). Several linear regression models with and without the country controlled dummy variables were conducted, respectively. Results indicated that principals’ perceived distributed and instructional leadership practices are significant predictors of staff mutual respect in the school. Nevertheless, such leadership styles did not appear as important factors for school delinquency and violence. School size and socio-economic status turned out to be the two most important factors predicting school safety. These results add nuance to the findings of previous studies that principals’ emphasis on instructional practice and sharing leadership can play a significant role in promoting the trust, collegiality and respect among staff. However, more than such leadership styles may be needed for creating a safe and orderly school environment.

How school context and educator characteristics predict distributed leadership: A hierarchical structural equation model with 2013 TALIS data

Yan Liu; Mehmet Sukru Bellibas; Susan M. Printy

Distributed leadership is a dynamic process and reciprocal interaction of the leader, the subordinates and the situation. This research was inspired by the theoretical framework of Spillane in order to contextualize distributed leadership and compare the variations using the Teaching and Learning International Survey 2013 data. The two-level structural equation model utilized the school contextual variables and staff characteristics as exogenous and endogenous variables simultaneously in order to investigate the reciprocal effects of these variables on each other, and the ultimate influences on the extent to which leadership is distributed. The results suggest mutual respect among staff, funding resource of the school, together with principals gender and employment status, are critically important factors with regard to the extent of distributed leadership in a school.

Investigating professional learning communities in Turkish schools: the effects of contextual factors

Mehmet Sukru Bellibas; Okan Bulut; Serafettin Gedik

A great number of studies have focused on professional learning communities in schools, but only a limited number of studies have treated the construct of professional learning communities as a dependent variable. The purpose of this research is to investigate Turkish schools’ capacity for supporting professional learning communities and to examine factors that account for variation in the current level of development. The data for this study were collected from 492 school staff members, including teachers, principals and assistant principals, working at 27 schools across nine provinces of Turkey. Results indicate that school staff had a culture of sharing and collaboration, but suffered from a lack of material and human resources required for supporting effective learning communities. The experience of the staff, as well as the size and socioeconomic status of the school, appeared to be the most important factors in predicting the variation in the available professional learning communities. The results are discussed considering current educational policy and practice in Turkey.

Teachers’ perceptions of the quantity and quality of professional development activities in Turkey

Mehmet Sukru Bellibas; Emine Gumus

Abstract Professional development for teachers has been a substantial issue in contemporary educational research and policy. Yet, opportunities for professional development activities have been very limited in Turkey. In this study, we examined Turkish teachers’ involvement in professional development activities by comparing their participation with the level of participation in top-performing countries in the Trends in International Mathematics and Science Study 2011, including Singapore, South Korea, Hong Kong, Taiwan, and Japan. Then, we also conducted face-to-face interviews with 13 Turkish mathematics and science teachers in order to explore their views about the current professional development opportunities for teachers in Turkey. The results of this study indicate that, when compared with teachers from Turkey, a larger proportion of teachers in the top-ranking countries participated in professional development activities in most of the sub-categories of professional development in both mathematics and science. In line with this finding, results of the qualitative analysis suggest that most of the teachers in Turkey are not happy with the quantity of professional development activities available to them. In addition, teachers believe that the quality of professional development provided to teachers is low in terms of its connection to the practice of teaching. This situation might hinder teachers’ performance and negatively impact student achievement in Turkey.

The effects of professional development activities on principals’ perceived instructional leadership practices: multi-country data analysis using TALIS 2013

Emine Gumus; Mehmet Sukru Bellibas

Abstract The purpose of this study was to investigate the extent to which professional development predicts principals’ instructional leadership in order to identify whether a relationship exists between the duration of principals’ participation in distinct professional development activities and their perceived practice of instructional leadership while controlling for several principal and school characteristics. The data employed in this study came from the 2013 teaching and learning international survey, which was conducted by the organisation for economic co-operation and development. Four multivariate regression models with the country-controlled dummy variable were implemented in the analysis of the data. The results indicated that the more principals take part in contemporary professional development activities such as professional networking, mentoring and research activities, the more often they engage in instructional leadership practices. However, no relationship between more traditional types of professional development activities, such as courses, conferences, and observational visits, and principals’ instructional leadership, was found. The results have substantial implications for policy-makers and practitioners worldwide, suggesting that any professional development designed to get principles involved in more instructional leadership practices should be based on the contemporary type of professional development activities.

The Evolution of Leadership Research in Higher Education for Two Decades (1995-2014): A Bibliometric and Content Analysis

Murat Esen; Mehmet Sukru Bellibas; Sedat Gumus

ABSTRACT The present study aims to examine the leadership research in higher education in order to shed light on its development during the last two decades by revealing the evolving trends in research on leadership in higher education, the most prominent scholars working on related research, the most popular topics in related research, and the countries in which the related studies are based. Bibliometric method was employed in the analysis of the original research and review papers published in five prominent higher education journals between 1995 and 2014: Higher Education, Research in Higher Education, Studies in Higher Education, The Journal of Higher Education and The Review of Higher Education. The results of this bibliometric analysis show that the majority of the related articles come from three countries: the U.S.A., the UK and Australia. It is also found that the leadership research in higher education is still very scarce and has not shown any meaningful increase during the last two decades. In addition, content analysis is used to provide more in-depth information about the topical focus, purpose and methodology of the selected articles. The results of content analyses are discussed in detail, and suggestions for the future research are provided.

Multilevel analysis of the relationship between principals’ perceived practices of instructional leadership and teachers’ self-efficacy perceptions

Mehmet Sukru Bellibas; Yan Liu

Purpose The purpose of this paper is to investigate the extent to which principals’ instructional leadership predicts teacher self-efficacy, in order to identify whether a relationship exists between principals’ perceived instructional leadership practices and teachers perceived self-efficacy in classroom management, instruction, and student engagement, while controlling for several principal, teacher, and school characteristics. Design/methodology/approach The data employed in this study were both teacher- and school-level data sets obtained from the Teaching and Learning International Survey, which was administered by the Organization for Economic Co-operation and Development in 2013. A two-level mixed model was employed in the analysis of the data by adding adjusted weights at both levels for the complex survey data. Findings The results indicated a significant and positive relationship between principals’ perceived instructional leadership practice and teachers’ self-efficacy in all three aspects. Also, gender, experience, tenure status, and formal in-service training of teachers were found to be the key factors that have significant effects on teachers’ self-efficacy perceptions. Practical implications Findings suggested that international effort for mandating instructional leadership in schools is a worthwhile strategy, which can help teachers develop a greater sense of ability in classroom management, instruction, and student engagement. Originality/value This study is the first of its kind to examine the relationship between instructional leadership and teachers’ perceived self-efficacy in multiple areas related to teaching.
