This study aims to determine the effect sizes of burnout levels of educational stakeholders in terms of marital status. It consists of classroom and branch teachers, preschool teachers, principals and vice-principals, supervisors and academicians. 49 empirical studies meeting the inclusion criteria were included. Maslach Burnout Inventory (MBI) was the only inventory used in included studies. 49 effect sizes (Cohen's d) were calculated for each of the dimensions of MBI. For emotional exhaustion, depersonalization and (reduced) personal achievement, combined effect sizes were calculated as -0,035, -0,109 and 0,039 respectively for random effect model. These results indicate that the effect sizes for marital status were on trivial level and favouring single educators in emotional exhaustion and depersonalization dimensions whereas for married ones in personal achievement dimension. Due to medium heterogeneity, moderator analyses were also done.

This meta-analysis study aims to synthesize the results of individual studies on respectively small samples investigating the correlations between Mathematics anxiety and Mathematics achievement. Meta-analysis included a total of 11 studies which investigated the association between Mathematics anxiety and Mathematics achievement on Turkish students which were published between 2005 and 2014. These studies were conducted totally on 8327 students from different educational stages. The results of the analysis for all eleven studies involved suggested negative and statistically significant correlations between mathematics anxiety and mathematics achievement. The combined effect size was calculated for all studies according to both Fixed (r=-.39) and Random (r=-.44) Effect Models. Moderator analysis based on the school level revealed that the combined effect size for the studies conducted at middle school level was significant, negative and at moderate level. In addition, the effect size for the studies conducted at high school level was significant, negative and at moderate level. Moreover, the comparison between the combined effect sizes with regard to different school levels revealed a statistically significant difference in favor of middle school level.

Problem Statement: Since conflict is an organizational phenomenon, its comparison between other organizational variables to find possible associations has been an important research motive. Relevant researchers have found significant correlations between conflict handling strategies of principals of different genders and school culture, emotional intelligence and conflict management styles, teachers' self-efficacy beliefs and conflict solution styles. Considering the rapid development of communication and the need for organizations to change, an increase in individual differences between organization members has become inevitable today. This also causes increased conflicts between organization members who are constantly interacting with each other. Poor communication underlies the interpersonal conflicts. The degree of interpersonal communication significantly determines the organizational performance and information transmission. Each education organization, like other organizations, is composed of people with different personalities, perceptions, attitudes, value judgments, personal goals, and expectations. Individual differences cause some problems. Solution of the problems seems to be closely associated with communication competence organization members have.

The main aim of this study was to gather teachers' views to determine the effect size of gender differences on the instructional leadership behavior of school principals. The standardized mean difference (SMD) was calculated to measure the effect size in this study. An initial search yielded 126 studies on the research topic, which consists of master theses, doctoral theses, and conference proceedings. After a detailed inclusion process, 38 studies, having data according to coding protocol, were included in the meta-analysis. The total study sample was 15,280 teachers of which 7,236 were males and 8,044 were females. The calculated effect size (SMD) for the random effect model was d = 0.048 [0.001 -0.094], which indicated with statistical significance that male teachers were favored more.
