This book offers practical guidance for understanding and implementing APA Style Journal Article Reporting Standards (JARS) and Meta-Analysis Reporting Standards (MARS) for quantitative research. These standards provide the essential information researchers need to report, including detailed accounts of the methods they followed, data results and…

Many thesis, dissertations, and articles have been written on whether the concept of multiple intelligence has achieved the expected success in educational environments that has been established in accordance with the multiple intelligence principle and whether such developments have had a positive influence on the attitudes of students towards…

The vast majority of meta-analyses uses summary/aggregate data retrieved from published studies in contrast to meta-analysis of individual participant data (IPD). When the outcome is continuous and IPD are available, linear mixed modelling methods can be employed in a one-stage approach. This allows for flexible modelling of within-study…

Background: Model-based meta-analysis (MBMA) is increasingly used to inform drug-development decisions by synthesising results from multiple studies to estimate treatment, dose-response, and time-course characteristics. Network meta-analysis (NMA) is used in Health Technology Appraisals for simultaneously comparing effects of multiple treatments,…

Studies combined in a meta-analysis often have differences in their design and conduct that can lead to heterogeneous results. A random-effects model accounts for these differences in the underlying study effects, which includes a heterogeneity variance parameter. The DerSimonian-Laird method is often used to estimate the heterogeneity variance,…

Social sciences librarians have an interest in supporting systematic reviews, but the available guidance is focused on health sciences settings. This study contributes guidance specifically for social sciences librarians using the Campbell Collaboration's standards to evaluate the search methods reported in systematic reviews on K-12 mathematics…

Background: Adults with intellectual disabilities are reported to be highly inactive, with research required to understand contributory factors. This systematic review aimed to investigate gender differences in physical activity (PA) and sedentary behaviour (SB) in adults with intellectual disabilities. Methods: This systematic review was reported…

The purpose of this study is, by using meta-analysis method, to examine whether there is a significant difference in the effect size of the Technological Pedagogical Content Knowledge (TPACK) according to gender. For this purpose, it was examined whether both Technological Pedagogical Content Knowledge and the knowledge types related to TPACK…

Dissertations present significant challenges to all doctoral students but these challenges are often greater for online students. Research shows that as many as 50% of all doctoral students do not complete their degrees, and this number is likely even higher for online students. One reason for this may be that online doctoral students do not have…

Conceptual frameworks are conjectural/hypothetical research tools that are particularly important and widely used in the disciplined inquiry, including educational (technology) research. However, there is a lack of guidance on how to construct them. Hence, the objective of the current research was to provide a methodological perspective through a…

Multisite research (MSR) offers the key advantages of greater statistical power and external validity via larger and more diverse participant pools. In second language acquisition (SLA) research, recent developments in meta-analysis have created a robust foundation for MSR. Although logistical and financial obstacles can complicate expansion…

A third level of educational research is emerging, in addition to original research and secondary-level reviews. Whereas most third-level research syntheses focus on rather restricted topical areas, this study introduces a comparative and integrative overview of prominent second-order research on teaching, including many different types of reviews…

In this COVID-19 pandemic, learners across the world are encouraged to stay at home receiving online education, which has nearly caused various learning outcomes. It is thus necessary to analyze online learning outcomes, as well as their gender differences to provide constructive references for learners, teachers, and technology developers. This…

Administration and governance of schools in Turkey have a complex structure and process. Within the centralized structure, the procedures in educational activities are managed by school principals. In the Turkish literature, there are studies showing leadership styles of school leaders based on the leadership theories borrowed from different…

E-learning has been widely used in higher education as it provides better access to learning resources online, utilising technology to enhance learning. Despite growing evidence claiming that e-learning is as effective as traditional means of learning, the evidence is still very limited. This protocol aims to measure the impact of e-learning as…
