This study examined the effect size of professional development programs on teachers' science teaching by meta-analysis method. For this purpose, literature review was made on existing national and international studies. In this context, master's thesis, doctoral dissertation, and articles conducted between 1990 and 2019 were appropriate for the…

This meta-analysis study aims to quantify the group differences in reading skills between children with cochlear implants and their hearing peers and between children with cochlear implants and children with hearing aids (aged between 3 and 18 years old). Of the 5,642 articles screened, 47 articles met predetermined inclusion criteria (published…

Engagement in early childhood has been linked with later achievement, but the relation between these variables and how they are measured in early childhood requires examination. We estimated the overall association between academic engagement and achievement in children prior to kindergarten entry. Our systematic literature search yielded 13,521…

Integration of learning has emerged as a central concept in research about learning and curriculum in higher education. While the term is frequently used, integration of learning is taken up in a variety of ways in higher education contexts, disciplinary and professional fields. This qualitative synthesis asks: what deeper insights and new…

This meta-analysis assesses the predictive validity of the Graduate Record Examination (GRE) across outcome variables, including grade point average, for graduate students. In addition to aggregate effects, this paper also assessed changes in observed effects over time as related to increasing diversity in the graduate student population and as a…

This study aims to determine the effectiveness of ethnomathematics-based learning on students' mathematical literacy through a meta-analysis study. Primary studies were collected from Google Scholar and ERIC databases based on the inclusion criteria. The results of the literature review obtained 16 studies, either from theses, proceedings, or…

Emotion regulation (ER) represents an important factor in youth's academic wellbeing even in contexts that are not characterized by outstanding levels of academic stress. Effective ER not only enhances learning and, consequentially, improves youths' academic achievement, but can also serve as a protective factor against academic burnout. The…

Autistic adults are at increased risk of both mental and physical health difficulties, and yet can face barriers to accessing healthcare. A meta-ethnographic approach was used to conduct a review of the existing literature regarding autistic adults' experiences of accessing healthcare. Four databases were systematically searched for qualitative…

Amid ongoing conflicts globally, the number of refugees has continued to grow, and half of them are children. Education not only stands as a fundamental human right for refugees but also as a vital pathway for their integration and resettlement in the future. Thus, refugee education prioritizes quality education for refugee learners within their…

In the present meta-analysis, we systematically examined the association between students' initial level of metacognition and their academic achievement at least three months later. Using multilevel meta-analysis as well as meta-analytic structural equation modelling, we analysed data from 71,171 students provided by 28 independent studies. The…

The ethnomathematics approach is considered effective on students' mathematics learning achievement. Integrating culture and mathematics can provide meaningful mathematics learning so that it makes it easier for students to understand mathematical concepts. However, previous research investigating the effectiveness of applying an ethnomathematics…

The purpose of the present study was to examine the effect of individual and school average achievement on students' self-concept in science. The data of the last four Trends in International Mathematics and Science Study (TIMSS) cycles were used, and a two-stage individual data meta-analysis was conducted to examine the relationship between…

A considerable body of literature exists pertaining to realistic mathematics education (RME) and its correlation with mathematical literacy, with numerous studies demonstrating incongruent results. The principal objective of this meta-analysis is to systematically investigate the overarching influence of RME on mathematical literacy within the…

Learning analytics has received increasing attention in the field of education. However, few studies have investigated the overall impact of learning analytics interventions on learning achievements. This study aims to close this research gap and examine the sizes of the overall effects of learning analytics interventions on learning achievements…

In this article, we introduce this second special issue on the assessment of perfectionism along with an overview of developments in the perfectionism field over the past 30 years following the shift to studying perfectionism as a multidimensional construct. We examine some key contributions over the past decade, including the proliferation of…
