In this article, several ways to adjust gross school effects are discussed to set the stage for estimating treatment effects in schooling. Although it is quite hazardous to hypothesize realistic benchmarks for results from meta-analyses, because of the dependency of effect sizes on subject matter area, grade level, and study characteristics, a…

Previous reviews have highlighted parent-child connectedness and communication as important protective factors against adolescent substance use. However, these reviews focus on single substances such as alcohol. An integrative review of the literature was conducted to examine which elements of parent-child connectedness and substance-use specific…

Applying meta-analytic review methods to evidence published in the past 20 years, this paper conceptualizes the critical path tying school leadership to student achievement by highlighting the importance of collective teacher efficacy (CTE). This paper presents the following: 1) CTE positively impacting student learning; 2) school leadership…

The current project aims at providing evidence-based implications for successful use of mobile technologies for teaching and learning. A systematic review of quantitative and qualitative research studies investigating the impact of tablet use on students' achievement has been undertaken. A targeted search and rigorous review of published research…

Purpose: The growing public interest in vocational education and training (VET), most recently since the economic crisis of 2007/2008, has led to an exponential increase in articles with a vocational focus, underscoring the need for review studies for the purposes of systematic knowledge aggregation, clarification and interpretation. We assume…

The objectives of this two-part study were to: (a) investigate English learner (EL) accommodation practices on state accountability assessments of reading/English language arts and mathematics in grades 3-8, and (b) conduct a meta-analysis of EL accommodation effectiveness on improving test performance. Across all distinct testing programs, we…

This meta-analysis investigated the relations between creative self-efficacy (CSE) and creativity measures and hypothesized that self-assessed questionnaires would have a different relation to self-efficacy beliefs compared to other creativity tests. The meta-analysis synthesized 60 effect sizes from 41 papers (overall N = 17226). Taken as a…

In this study, it is aimed to determine the effect of visualization on mathematics achievement in the thesis studies conducted in Turkey. In this context, the findings obtained from individual studies are combined via meta-analysis. For this purpose, Council of Higher Education (CoHE) National Thesis Center database was thoroughly scanned by using…

Openness to experience has often been linked to academic achievement because it subsumes traits such as curiosity, open-mindedness, thoughtfulness, and intellectuality. However, recent meta-analyses have reported rather small true correlation estimates. In this article, we first provide a comprehensive rationale for a relationship between openness…

Considerable academic attention has been placed on analysing whether, and to what extent, socioeconomic background affects higher education participation. However, the use of socioeconomic status (SES) is problematic as it may be constructed from various data sources. Similar issues can be inherent in study design-related operationalisation…

The present study aims to demonstrate, by means of a meta-analysis, the effectiveness of Project-Based Learning in the context of academic performance and various study characteristics. For this purpose, the relevant literature was reviewed to identify studies using Project-Based Learning in the fields of physics, chemistry, biology, and science.…

Purpose: The purpose of this systematic review and meta-analysis was to establish a baseline of the vowel and consonant identification scores in prelingually and postlingually deaf users of multichannel cochlear implants (CIs) tested with consonant-vowel-consonant and vowel-consonant-vowel nonsense syllables. Method: Six electronic databases were…

Varying methods for evaluating the outcomes of single case research designs (SCD) are currently used in reviews and meta-analyses of interventions. Quantitative effect size measures are often presented alongside visual analysis conclusions. Six measures across two classes--overlap measures (percentage non-overlapping data, improvement rate…

This meta-analysis offers a snapshot of thirty-five years (1980-2015) of research on instructed second language acquisition (ISLA). Fifty-four empirical studies involving a total of 5,051 second language learners -- sampled from six applied linguistics journals, "Applied Linguistics, Language Learning, Language Teaching Research,"…

Practitioner research is a fourishing area with a signifcant body of theoretical and empirical research, but often researchers remain isolated, unaware of impactful work by colleagues in related felds. Exploratory Practice (EP) is one innovative form, uniting creative pedagogy and research methods. The potential contributions have hitherto been…
