This research aims to investigate the effects of leadership behaviour of school principals on teachers' organisational commitment in Turkey. The method of meta-analysis is used to calculate the effects size of leadership on teachers' organisational commitment. Besides this, leadership style, publication type and publication year are used as…

The acquisition of a language is a complex process. Applied Linguistics research tends to view this process as classroom-based. It is only more recently that learners, in particular young learners, are being placed in the centre of investigation in research exploring language learning from their subjective perspectives. To understand these…

A recent national report heartily supported arts integration as an effective, innovative, and cost-efficient way to address teachers' and students' needs; however, the report called for a better understanding of when, for whom, and what content areas are best served by arts integration methods. The effectiveness of drama-based pedagogy (DBP), a…

The purpose of this meta-synthesis is to formulate a hypothesis concerning the importance of diacritical marks in Arabic word recognition for typically developed Arabic readers. I propose that the importance of diacritical marks in Arabic word recognition varies as a function of grade level, stimuli frequency, and text affiliation. Stimuli…

Digital games (e.g., video games or computer games) have been reported as an effective educational method that can improve students' motivation and performance in mathematics education. This meta-analysis study (a) investigates the current trend of digital game-based learning (DGBL) by reviewing the research studies on the use of DGBL for…

Serious games have become increasingly available to educators. Empirical studies and meta-analyses have examined their impact on learning achievement. However, natural sciences could have a special relation to serious games by their systematic use of quantitative and predictive models that can generate microworlds and simulations. Since no known…

This study is a meta-analysis of the effects of out-of-school time (after school, summer camps, enrichment programs, etc.) on the student interest in STEM. This study was guided by the following research questions: (1) How effective is OST as a means to foster student interest in STEM? (2) How does the effectiveness of OST differ by program and…

This meta-analytic study compared the effect of peer-led learning versus non peer-led learning on students' cognitive achievement in post-secondary education. Twenty-eight studies published in English from six countries between 1993 and 2017 were identified and used in the analysis. Result of the analysis on the random-effect model showed a…

Although their research agendas may vary widely, school library researchers from around the world share the common goal of conducting studies designed to advance the field of school librarianship. International school library scholars are united in their efforts to prove that quality school library programs can have a significant impact on student…

While there are many ways to author text today, writing with paper and pen (or pencil) is still quite common at home and work, and predominates writing at school. Because handwriting can bias readers' judgments about the ideas in a text and impact other writing processes, like planning and text generation, it is important to ensure students…

Given that consultation has consistently yielded benefits for clients and consultees, it is likely an effective method of promoting family-school engagement. Thus, this meta-analysis examined the effects of consultation-based family-school engagement on child and parent outcomes, and complementary intervention methods used in conjunction with…

The current study examined the effect of academic interventions and modifications on behavioral outcomes in a meta-analysis of 32 single-case design studies. Academic interventions included modifying task difficulty, providing instruction in reading, mathematics, or writing, and contingent reinforcement for academic performance. There was an…

Researchers have increasingly investigated sources of variance in reading comprehension test scores, particularly with students with reading difficulties (RD). The purpose of this meta-analysis was to determine if the achievement gap between students with RD and typically developing (TD) students varies as a function of different reading…

This research study aims to investigate the effects of school leadership on student achievement in USA and Turkey. The method of meta-analysis is used to calculate the effect size of school leadership on student achievement. Thirty-nine research studies were included in this study. However, several publications included in the research have…

The 3D virtual worlds (3DVWs) were widely used for language learning in the past two decades. Although numerous research studies acknowledged the affordance, a full-scale investigation that discussed how they can be applied to language learning with substantial evidence of effect sizes were not presented. Thus, this analysis aimed to synthesize…
