Although previous meta-analyses have indicated a connection between inquiry-based teaching and improved student learning, the type of instruction characterized as inquiry based has varied greatly, and few have focused on the extent to which activities are led by the teacher or student. This meta-analysis introduces a framework for inquiry-based…

Purpose: The purpose of this paper is to present a meta-analysis of a subset of published empirical research papers that measure learning capability and link it to organizational performance. It also seeks to examine both financial and non-financial performance. Design/methodology/approach: In a search of published research on learning capability…

A cross-sectional case-control study was carried out to evaluate the concentrations of metallic elements in the hair of 44 children with diagnosis of autism and 61 age-balanced controls. Unadjusted comparisons showed higher concentrations of molybdenum, lithium and selenium in autistic children. Logistic regression analysis confirmed the role of…

With increasing globalization of business and diversity within the workplace, there has been growing interest in cultural differences in employee commitment. We used meta-analysis to compute mean levels of affective (AC; K=966, N=433,129), continuance (CC; K=428, N=199,831), and normative (NC; K=336, N=133,277) organizational commitment for as…

Research studies reflect mixed results on whether or not service-learning increases student learning outcomes. The current study seeks to reconcile these findings by extending a meta-analysis conducted by Novak, Markey, and Allen (2007) in which these authors examined service-learning and student learning outcomes. In the current study, 11…

The modality effect is a central issue in multimedia learning [see Mayer (Cambridge University Press, 2005a), for a review]. Sweller's Cognitive Load Theory (CLT), for example, presumes that an illustrated text is better understood when presented visually rather than orally. The predictive power of CLT lies in how it links in to Baddeley's (1986)…

The usage of technology within the educational department has become more vital by each year passing. One of the most popular technological approaches used is the e-learning environment. The usage of e-learning environment in education involves a wide range of types of students, and this includes the hearing impaired ones. Some adjustment or…

A recent study of scholarship on educational leadership and management in East Asia identified a rapidly growing corpus of published studies focusing on educational leadership and management in Hong Kong. This article undertakes a "topographical analysis" of this literature with the aim of describing the nature of topics and research…

Many children with pervasive developmental disorders (PDD) exhibit behaviors and symptoms of attention-deficit/hyperactivity disorder (ADHD). We sought to determine the relative efficacy of medications for treating ADHD symptoms in children with PDD by identifying all double-blind, randomized, placebo-controlled trials examining the efficacy of…

In this essay, Sharon Subreenduth explores how social justice policies have both global-local and historical dynamics and maintains that, as a result, dominant Western models of social justice limit engagement with alternative modes of understanding social justice in non-Western locations. She uses the South African experience as a case study for…

Objective: Service use trends showing increased off-label prescribing in very young children and reduced psychotherapy use raise concerns about quality of care for early disruptive behavior problems. Meta-analysis can empirically clarify best practices and guide clinical decision making by providing a quantitative synthesis of a body of…

Over the past 20 years, there has been much research on how people learn from case comparisons. This work has implemented comparison activities in a variety of different ways across a wide range of laboratory and classroom contexts. In an effort to assess the overall effectiveness of case comparisons across this diversity of implementation and…

Children with Specific Language Impairment (SLI) find it effortful to learn to talk and these difficulties can be persistent. Given the importance of language to human behaviour, it is not surprising to find that language difficulties are a risk factor for associated difficulties in other aspects of children's development. This article asks…

Peer tutoring is an instructional strategy that involves students helping each other learn content through repetition of key concepts. This meta-analysis examined effects of peer tutoring across 26 single-case research experiments for 938 students in Grades 1-12. The TauU effect size for 195 phase contrasts was 0.75 with a confidence interval of…

The use of manipulatives to teach mathematics is often prescribed as an efficacious teaching strategy. To examine the empirical evidence regarding the use of manipulatives during mathematics instruction, we conducted a systematic search of the literature. This search identified 55 studies that compared instruction with manipulatives to a control…
