According to the socio-ecological model, the social environment contributes to the acquisition and maintenance of negative attitudes towards ethnic minority groups. However, the strength of the association between negative attitudes at different levels (i.e. individual, peers) and ethnic bullying and discrimination has not yet been assessed. A…

Accurate monitoring of performance in problem-solving tasks is an important prerequisite for students' future academic success. A wide variety of interventions aiming to enhance students' monitoring accuracy have been developed, but their effectiveness is not apparent from the individual studies in which they have been examined. This meta-analysis…

The effect that online extensive reading (ER) of English texts has on learners' reading comprehension and motivation to read is not well understood. The purpose of this systematic review was to examine the efficacy of online ER by examining quantitative and mixed-methods studies that examined the effect of online ER on learners' reading…

Academic dishonesty is a pervasive problem undermining the effectiveness of educational institutions. From a motivational perspective, researchers have proposed achievement goals as antecedents of academic dishonesty. Empirical findings corroborate the notion that mastery goals (focus on learning and competence development) are negatively linked…

There is considerable concern that many adolescents do not attain the writing competence needed to be successful in school, their personal lives, or the workplace. Ensuring that students acquire this competence is a basic responsibility of schools. In order to meet this objective, teachers need access to effective practices for teaching writing.…

This study aimed to examine the efficacy of school-based e-cigarette preventive interventions via a systematic review and meta-analysis. We searched Medline, Embase, PsycINFO, Scopus, CINAHL, Cochrane, and clinical trial registries for studies published between January 2000 and June 2023 using keywords for e-cigarettes, adolescents, and school. Of…

Understanding rational numbers is critical for secondary mathematics achievement. However, students with mathematics difficulties (MD) struggle with rational number topics, including fractions, decimals, and percentages. The purpose of this systematic review was to describe the instructional foci of rational number interventions, determine the…

The present study examines the existing published research about the effectiveness of learner-generated highlighting and instructor-provided highlighting on learning from text. A meta-analysis was conducted of scientifically rigorous experiments comparing the learning outcomes (i.e., performance on memory and/or comprehension tests) of students…

Problematic smartphone use has become a global problem with broad implications for education. The present meta-analysis studies the relationship between problematic smartphone use and procrastination in students. A literature search was conducted in Web of Science, PsycInfo and Scopus databases, obtaining a total of 18 articles that met the…

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…

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 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…

Higher-order thinking skills (HOT) are expected to be skills needed now and in the future. Many learning strategies are applied to increase HOT. However, how effective is this in improving students' HOT abilities? This study will examine how effective learning is to improve HOT thinking skills. We use meta-analysis research techniques to analyze…

The two main purposes of the current meta-analysis were (1) to determine the relation between socioeconomic status (SES) of students and academic performance (AP) and (2) and evaluate the effect of several potential moderating factors in this relation. Data covered the publications between 2010 and 2019, and the dataset consisted of 48 independent…

This meta-analysis synthesized the findings of experimental and quasi-experimental studies to determine the efficacy of math interventions for enhancing the word problem-solving accuracy of students with mathematics difficulties in Grades 4 to 12. Further, we identified intervention and design characteristics that moderate the effectiveness of…
