One of the main goals of an individual participant data meta-analysis (IPD-MA) of intervention studies is to investigate whether treatment effect differences are present, and how they are associated with patient characteristics. Examining treatment heterogeneity due to a continuous covariable (e.g., BMI or age) may be challenging, since there is…

Evidence suggests that cyberbullying among school-age children is related to problem behaviors and other adverse school performance constructs. As a result, numerous school-based programs have been developed and implemented to decrease cyberbullying perpetration and victimization. Given the extensive literature and variation in program…

Meta-analytical methods face particular challenges in research fields such as social and political research, where studies often rest primarily on qualitative and case study research. In such contexts, where research findings are less standardized and amenable to structured synthesis, the case survey method has been proposed as a means of data…

Randomised controlled trials of cancer treatments typically report progression free survival (PFS) and overall survival (OS) outcomes. Existing methods to synthesise evidence on PFS and OS either rely on the proportional hazards assumption or make parametric assumptions which may not capture the diverse survival curve shapes across studies and…

Meta-analysis is a widely used methodology to combine evidence from different sources examining a common research phenomenon, to obtain a quantitative summary of the studied phenomenon. In the medical field, multiple studies investigate the effectiveness of new treatments and meta-analysis is largely performed to generate the summary (average)…

The purpose of this research is to make a meta-evaluation of the program evaluation studies on teacher training programs in Turkey. Meta-evaluation is the process of revealing the deficiencies and errors of the research as the last stage of the program evaluation process. In this context, the steps of the meta-evaluation processes were followed…

Metacognitive instruction supports L2 listening learners to enhance their listening comprehension skill. To date, some review studies have investigated this topic; however, none of them has reported quantitative and qualitative findings in the form of a systematic literature review. This research addresses this gap by collecting, analyzing, and…

Background: With the growing emphasis on computer science (CS) education in K-12 schools, numerous professional development (PD) programs for in-service CS teachers (CS-PD) have been implemented over the past decades. However, there is a lack of systematic review and meta-analysis to evaluate the effectiveness of these CS-PD programs. To address…

The purpose of the present study was to analyze the impact of technology on student foreign language learning, as it has been widely used to enhance language instruction over the past few decades. This multivariate meta--meta-analysis study aimed to examine the effects of technology on various aspects of language learning, including listening,…

An expanding literature has explored the impact of second language (L2) self-concept on language achievement and motivation. This review adopts a psychological lens to examine L2 self-concept, beginning with an outline of prominent theoretical frameworks: situated expectancy-value theory; Shavelson et al.'s (1976) hierarchical, multidimensional…

Happiness is being in an emotional state that can reflect a high level of mental and emotional well-being. We examined and explored the factors influencing happiness such as culture, socio-economic status (SES) and religious coping. It also identified the foremost and major factors influencing happiness. In this study the cultural indicators are…

A meta-analytic study was conducted of the "Unified Theory of Acceptance and Use of Technology" to understand higher education instructors use of technology in teaching and learning. Through broad searches of the years 2003-2023, 117 records were identified for initial review. After reviewing the studies and removing those studies that…

This meta-analysis included 27 empirical studies to explore the effectiveness of robot-assisted language learning (RALL) as well as the moderating effects of a number of variables. The comparison of 64 effect sizes from 2,637 participants indicated significant variability between the independent samples. The overall results showed that the…

Interventions are crucial in the learning analysis process. Learning analytics-based interventions are being widely applied in the field of education. However, it is currently unclear whether learning analytics-based interventions effectively enhance students' learning effects. To conduct a comprehensive review assessing the extent to which…

The unequal presence of women in scientific and technological fields compared to men may have its origins partly in the compulsory educational stages and performance of teachers involved therein. This study aims to systematically review the existing literature on science and technology teacher training to address the gender gap in STEM studies,…
