This study synthesized 14 published and unpublished group design and single-case design studies on bullying interventions for individuals with disabilities. The specific objectives were to examine the general characteristics and design qualities of the studies, quantify the magnitude of the intervention effects, and identify potential moderating…

This meta-analysis study aimed to scrutinize the effect of the problem-based learning (PBL) approach on students' academic achievement in science lessons compared to the traditional instructional approach. As research data, the researcher accessed 55 experimental studies as a result of steps of a systematic review with the keywords…

The effect size of psychological counseling based on the Cognitive Behavioral Therapy (CBT) approach on depression and anxiety, was conducted using a meta-analysis method. According to the defined criteria, eight primary studies on anxiety and 21 on depression are included in the meta-analysis. The effect sizes based on a random-effects model are…

In the literature, there are a great number of primary studies that examine the relationship between professional burnout, job satisfaction, and life satisfaction of education workers and that do not have consistent results. The aim of this study is to establish a model that will explain the life satisfaction of education workers by determining…

Previous research has evidenced a strong positive relationship between leisure print reading habits and reading comprehension across the lifespan. The rapid evolution of new forms of leisure digital reading could modify such a relationship. This meta-analysis extends previous research by analyzing the relationship between leisure digital reading…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

Academic success has become an important educational goal that directs the nature of a learning process. Peer instruction is one of the learning methods used to achieve this end. The impacts of peer instruction on academic achievement can be determined more clearly by taking a holistic perspective at past experimental studies conducted in this…

The topic of praise and more specifically, behavior-specific praise, in special education is complex. It requires an investigation of multiple types of praise in a variety of settings and a variety of individuals with even more severe intellectual and developmental disabilities and other impairments (IDDI). Historically, in much research,…

STEM education is applied to raise individuals having 21st-century skills based on the integration of science, technology, engineering, and mathematics. This paper aims to present the overall effect of STEM education on students' academic achievement by analyzing 64 research findings obtained from 56 quantitative studies published between 2014 and…

Meta-analytic reviews collect available empirical studies on a specified domain and calculate the average effect of a factor. Educators as well as researchers exploring a new domain of inquiry may rely on the conclusions from meta-analytic reviews rather than reading multiple primary studies. This article calls for caution in this regard because…

Background: In testing contexts that are predominately concerned with power, rapid guessing (RG) has the potential to undermine the validity of inferences made from educational assessments, as such responses are unreflective of the knowledge, skills, and abilities assessed. Given this concern, practitioners/researchers have utilized a multitude of…

The disparity in the results of the study of the correlation between religiosity and multiple intelligences is an important use of meta-analysis, so that it can be used as credible literature by looking at multiple intelligences not only as analytical intelligence. This study involved 3242 samples that varied, age, culture, and academics, from 18…

A variety of measures have been developed to quantify intervention effects for single-case experimental design studies. Within the family of non-overlap indices, the Tau-U measure is one of the most popular indices. There are several Tau-U variants, each one calculated differently. The appropriateness of each Tau-U variant depends upon the data…

This research is an extensive meta-analysis investigating the link between mathematical literacy and mathematics achievement which are tested mainly in PISA exams. With this aim in mind, first, the studies related to the research objective between the years 2003-2021 were examined. In the second stage, eight studies which met the research criteria…

As past studies showed mixed results, this meta-analysis determined game-based learning's overall effect on students' critical thinking and tested for moderators, using 21 effect sizes from 20 empirical studies of 1,947 participants. The results showed that game-based learning had a significant positive overall effect on students' critical…
